iOS App: HOOK

HOOK App
Hook on iTunes ($0.99, sometimes free)

What it is: A simple, minimalist, puzzle game of sequentially unraveling "hooks". There are 50 levels, with a slight increase in complexity as you move up. The interface is aesthetically pleasing and elegant. There's no time limits, menus, or statistics. If you make a mistake it simply restarts. Higher levels allow 3 mistakes before the level restarts.

For each puzzle you need to find the sequence in which each hook needs to be removed (otherwise they block each other) and then trace the hook back to its starting point where the removal is initiated. Once you initiate removal of a hook, the animation of it drawing in helps visualize the process. As each hook is removed, its entire path disappears. I find this process of solving each level especially rewarding. The next step may still be complex, but it's slightly simplified by previous success.

Screen Shot 1
In Screen Shot 1 you can see a simple level - level 4 (the first level where there is interaction among the hooks; in previous levels you can remove the hooks in any order). You can see the black circle that you press to initiate removal, and the hooks to be removed. You can see where a hook would block another one if it's removed in the wrong sequence (the one that curves upward, if it's removed before the hook whose point is wedged in the curve, would be caught in place).

How we can use it in Tx: The game-play is so simple, there's not much to plan. Just let your client solve the puzzle. I suggest always starting with the first levels because they help train for what to look for, and get a user adjusted to how the controls in the puzzle work (press the dot, watch the hook pulled in towards it).

The levels get more complex gradually, and the complexity is built in very clever ways. First more and more hooks are added so unraveling becomes more complicated. Screen
Screen Shot 2
Shot 2
shows an example of a slightly more complex puzzle level (level 12), where there are 6 hooks, and some are layered. The two hooks with starting points at the farthest to the left part of the puzzle can be removed first. So you can see the problem solving becomes not just more complex, but acquires more steps: you have to figure out which hooks are removable without being blocked by other hooks, and then you have to trace back their origins.

In more advanced levels the origin point also becomes less straightforward: more than one hook might be triggered by the same origin point, and other complexities are introduced as well, such as wireless activation of hooks and hinges that can be rotated to adjust which hook is activated. Screen Shot 3 of level 34 has an example of all of these added complexities: Note that there is only one activation point (the black circle) which is "wireless", and you have to adjust which hook gets activated by rotating the hinges. So the hook removal must still be sequential, and in this level the sequence is relatively simple with only 4 hooks to control, but the problem solving complexity is shifted to which hook is activated.

Screen Shot 3
There are no directions to follow - you learn the game-play as you work the levels. So we get to work on a skill that we rarely get a chance to address directly: the skill of learning. All the while using an elegant interface that clearly favors mature users over childish animation and distractions.

The music is relaxing, but I personally would still prefer to mute it and focus on levels of cuing I need to provide to my client. I would encourage the client to verbalize as much of the problem solving as possible, to better discern the breakdowns so I could provide targeted support for the needed skills, and help build up strategies. Since there are many levels and they go up in complexity gradually, allowing one to build success through practice before new obstacles are introduced, I imagine that - choosing wisely and knowing when to stop - frustration on the part of your client will be kept to a minimum.

Goals we can target in Tx with this app: Attention and memory goals, planning, reasoning, sequencing, problem solving. While I argue that most apps I review have some utility for addressing memory, this one in particular directly addresses learning. Short term/working memory is taxed in the problem solving process: One can trace a hook from its switch to its end and figure out a sequence for solving the puzzle, which as to be mentally manipulated and thereafter retained long enough to follow through. And as one gets better at solving the maximally simple puzzles, the complexity slowly builds, utilizing the strategies developed for earlier levels. Solving these puzzles also heavily depends, obviously, on visuospatial reasoning. As such, any field neglect will hamper one's progress, so cuing can be provided to draw attention to the neglected side.

Some specific examples:

1.  Allow your client to verbalize a solution to a puzzle. E.g., "I would pull in this hook first because nothing is in its way, and then it would also get out of the way of this second hook, and then I can pull that one in". Discuss it a little to build up context and assist with memory encoding & consolidation. Then after a short delay return to the puzzle for your client to implement (or have to re-generate) their solution (retrieval of memory or strategy; capitalizing on procedural memory).

2. Since the switch to pull in the hook and the hook itself are almost always in different visual fields (left/right, up/down) almost any puzzle would require scanning the full field, even the very first levels with just one or two hooks with no interactions between them. When the cause is on one side, and the effect on the other, tracking is key. For lateral neglect, therefore, even the simplest first puzzles should work.

iOS App: RGB Express - Mini Truck Puzzle

RGB Express App
RGB Express on iTunes ($2.99, sometimes free)

What it is: A simple puzzle game where you plan a route for the game pieces: Trucks that deliver same colored packages to same colored houses. You start at the truck, you map a path through the via point(s) to pick up packages, to the destination house. Trucks can't use the same road twice (neither theirs nor each other's). After you map a path for each truck you hit "play" to watch them drive.

The screen Shots show an example of one puzzle at a simple/mod complexity level. Screen Shot 1 is the starting position, and in Screen Shot 2 you see how the puzzle is solved: you draw the path of each truck to pick up the appropriately colored package and deliver it to the appropriately colored house without using the same road twice by either truck. Once you draw the solution, you press "play" and the truck driving and picking up/delivering packages is animated. Previous levels had one truck and many possible solutions, and subsequent levels may have more trucks/colors, and more than one package per truck resulting in more complicated routing and fewer possible solutions. There is no time limit to solving the puzzles, and you can redraw the paths until you're ready to hit "play" and test them.

Screen Shot 1
How we can use it in Tx: There are 3 key features of this puzzle game that benefit its use for treatment activities. First, it doesn't involve a time limit for solving each puzzle. The time limit, to me, is what eliminates many puzzle apps from being used in Tx. We want to challenge our clients in the skills we are working on, not frustrate them. More importantly, we want them to take the time to USE those skills and improve them.

The second useful feature of this app for Tx is its gradual increase in complexity. Unlike many puzzles that get too complex for most cog patients within just a handful of levels, this one increases the problem solving task slowly, and the increased complexity is focused on the reasoning aspects - that is, the exact skills we want challenged are the ones slowly increasing in complexity. Again, not the time limit or the distractions, but the specific spatial reasoning tasks: more complex routing for planning, more via points, additional colors to match, and eventually sequencing how many packages can be carried at once.

The third useful feature of this app for Tx is the ability to self correct: One can draw the possible routing solution, and if one determines there's a problem with it, one can redraw it before pressing the "play" button to animate the solution. So your client doesn't only get a chance to take their time planning a solution, they can produce a visual plan and determine its value before proceeding. This isolates some of the steps in problem solving and allows you as therapist to work on the component skills that require help and not merely the overall macro skill. The benefit of this aspect to Tx cannot be overstated. It is very rare to find a fun, motivating, task that allows us a glimpse into the micro component skills of reasoning.

Screen Shot 2
Although I don't list it as one of key beneficial features, there's one more thing I like about this app: It's simple and while it has use of color (necessary to the puzzle) and some animation, the color and animation are not distracting to the user. It doesn't feel inappropriately childish

So to use this in Tx you just let your client play the game, preferably on a large screen of an iPad or iPad mini. I usually have the sound on muted, and offer cuing as needed. Keep track of how much cuing was required to solve a puzzle, and what was most difficult (matching colors, drawing a path to destination and via points, addition of more via points or addition of more trucks, determining correctness of solution before hitting "play", etc.).

Goals we can target in Tx with this app: Planning a route for each truck via the point where the "package" is picked up to the destination (the house) requires problem solving, spatial reasoning, planning and scanning. Other skills engaged in solving these puzzles involve direction following, use of full visual field (as such, it can be useful to tasks targeting visual field neglect of various etiologies), sequencing (e.g., the order of packages before reaching the destination while avoiding the path of other trucks), focus/attention, categorization (colors, stopping points, destinations), and--as I always suggest--memory (e.g., to carry out the plan one comes up with to solve the puzzle). Also, as mentioned above, this task breaks up some of the components of problem-solving and allows you a glimpse into what specific component (planning, carry through, etc.) may need the most work.

Some specific examples:

1. For a lower functioning client you may want to work on recognizing a solution rather than generating one. Start at the lower levels with simpler road paths (like the one in the screen shots) and one truck picking up one package (one path to draw, one via point, one destination). Draw a route and ask if it's the shortest route to the destination. Draw one that passes the destination before the via point, and ask if that will work as a solution. Press "play" to determine if it works or not.

2. If you determine which increased challenge leads to the most errors (e.g., more complicated map or more via points or more trucks/colors) you can skip along to the levels that increase challenges in other areas but not the specific one causing problems so your client can continue to be challenged but not overwhelmed.

I also recommend doing these on your own so you can access all the levels in Tx because, as with most puzzles like this, advanced levels are unlocked as you complete previous ones. So make sure you have access to various levels that doesn't depend on your current client's progress.

Android and iOS app: Constant Therapy

Constant Therapy App
Apps: iPad Constant Therapy app on iTunes (free)
Android Constant Therapy app on Google Play (free)
Website: constanttherapy.com

What it is: A Speech Therapy tool for Cognitive-Communicative rehab. The app includes a large variety of language and cognitive tasks that can be customized to complexity level of your clients. It is free for clinicians, researchers and students; clients have to buy a subscription.

Here is how it works: As a clinician you would have this app on your device (again, for you an account is free). When you have a client with cog-com goals, you would create an account for them on your device (this is all still free). You would choose appropriate tasks customized to your client's diagnosis and severity, functional needs and skills.

The variety of their tasks is extremely satisfying. For language they have tasks for auditory compr, naming, writing, reading and sentence planning; for cognition they have attention, visual processing, mental flexibility, memory, problem solving and executive skill tasks. This list does not do justice to the variety and creativity of these tasks. I'm not sure the exact number but I counted 34 language tasks and 31 cognition tasks. To get a better idea very quickly, I urge you to hop over to this page and just glance at these tasks (when you mouse-over any task, it shows you a screen shot): http://constanttherapy.com/constant-therapy-tasks.

In Tx: The program allows you to select which tasks to use with your client, and at the level of each task you can adjust the complexity. You then get a baseline for each task for the individual client, and the program continues to keep track of progress (as well as usage). There's too many activities that address a large variety of goals to go into detail here. What I can say is that the activities I've seen and tried are created almost exactly how I would have conceptualized them, and I found it was very intuitive how to explain the clinical justification for spending time on these to patients and their families. Also, CT's website discusses Evidence Based Practice (EBP) implementation.

Outside Tx: You can select the tasks you want as "homework" for your client. This is where their own subscription becomes beneficial: The clients that can continue to complete these tasks outside of the therapy session can purchase a subscription (http://constanttherapy.com/pricing). They should do it using the account you create for them in session, so that the homework you assign can show up in their account, and their progress with tasks in sessions and on their own can be tracked (from within the account of the clinician that originally created their login). This extends your therapy outside the session: you, the SLP, are making clinically-informed choices re which tasks are most appropriate and beneficial, and are able to modify your decision based on progress feedback. Very few tools allow this kind of flexibility for clinicians to address patient needs beyond the therapy session.

My experience: I've used it only with adults for both cognitive and language intervention. I found it extremely age-appropriate, interesting and motivating. My clients seemed to enjoy the tasks, and I can't say enough about the ability to track progress in such an individualized (per client, per goal, per task) manner. A few outpatients have purchased a subscription and they (and their spouses) report good motivation to work on tasks at home.

Bottom line: I can absolutely recommend this program/service to both clinicians and clients. For the clinician, you will find this to be one of your most used apps on your tablet. For the client, based on the prices in 2014-2015 the feedback I've received is that it is well worth it.

iOS app: Missing Link

Missing Link App
Missing Link on iTunes (free)

What it is: A puzzle where 3 words are presented with missing letters, and solving the puzzle requires filling in the blanks to find these words. The main clue you get is that in all 3 words the same string of letters is missing.

There are 3 difficulty levels: easy, medium and hard. At easy level there's usually 2 letters missing (see Screen Shot 1), 3 at medium level, and at hard level there's shorter words with 3 blanks, so a larger part of the word is obscured.

Screen Shot 1: Easy Level
The layout is clean enough, even with the ads that pop up at the top in the free version. It resembles
an old-style typewriter (with sounds to match) and is obviously directed at adult populations.

How we can use it in Tx: As far as language goals go, even at simple level this is not the easiest game because the target words aren't the most common. As such, I would use this app for the higher functioning language client, stick to the simplest level and provide a lot of cues.

As far as reasoning goals go, the directions are simple (find 2 letters that would complete all 3 words) and yet not automatically familiar (there's not a lot of games/puzzles like this) so you have a chance to work on direction-following, and on recall of directions from one puzzle to the next. In this context, you can work with mod impaired clients as long as they don't have comorbid symbolic dysfunction.

Cuing could involve recognizing letter/sound combinations in English (e.g., if you have a verb like "keel" in screen shot 1, followed by blank-blank-g, familiarity with English should make one think of the "-ing" ending); or cuing could involve clues towards guessing the words themselves (e.g., "what's another word for 'airplane'?"). You can enter letters (even wrong ones) and ask the client whether they recognize each entry as a word. Word-recognition is an important aspect of symbolic dysfunction, although normally I'd choose simpler and shorter words for such a task unless the client was pretty high functioning.

Goals we can target in Tx with this app: Language goals involving reading, word-finding, symbolic dysfunction and intelligibility (see example 3 below); memory/recall goals related to direction following and sequencing, as well as reasoning goals.

Some specific examples:

1. Higher functioning client with language goals, you can solve the puzzle providing cues as needed (start with sound/letter familiarity cues as discussed above, then add word definition hints if needed). Once solved request client form a sentence with each word, followed by one sentence using all 3 (it can be silly, as long as it's grammatically correct).

2. For client with language goal, after solving the 3 words, have them make a list of 3-5 additional words that contain the string of letters missing from the current puzzle.

3. For a client with intelligibility goals, the simple level puzzles in this app provide great practice word lists since they are mostly 2 or more syllables long. So, solve the puzzle for fun, then use the words for intelligibility strategies practice, and to make sentences (silly sentences are really great for intelligibility practice because they lack context and thus have greater dependency on each word being heard and understood).

Android, Windows and iOS app: 4 Pics 1 Word

4 Pics 1 Word App
4 Pics 1 Word for Windows RT, for Android devices on Google Play, and for iOS devices from iTunes (all are free at this time). Also available for Nook from Barnes and Noble, and for Kindle from Amazon (these cost $0.99, and possibly are from a different developer).

What it is: A simple puzzle that presents 4 pictures that have one word in common, and you have to guess what that word is. See screen shot below where the target word is "sweet".

The gameplay is simple. Just start it and it presents 4 pictures on the screen (beautiful and high resolution), 12 letters, and blanks for each letter of the target word. Figure out what word the 4 pictures have in common and fill in the answer. You can turn off the sound if you want (although it's not annoying, just sound effects for when you select letters) and you can turn off the notifications re "buying" hints and such. As you progress through the puzzle, you win "coins" with each correct answer, and then you can purchase hints with these coins. Players can also buy these "coins" via in-app purchase.

How we can use it in Tx: Solve the puzzles with your client, providing cues as needed. You can talk about each picture of the 4 presented per puzzle, ask questions and elicit replies. In many cases the target word has more than one meaning (e.g., "sign" where it could be a noun or a verb) which provides context for some great language intervention. Solving the puzzles is great, but the path to solving each puzzles provides context for some useful interaction.

The main problem with this app is that you can't go back to puzzles you've solved (unless you remove the app and reinstall it, presumably). The puzzles do get progressively more difficult but very gradually and not by much. It's not optimal but for now you can use it until it's too difficult for your population, then reinstall and start from the beginning. And hopefully down the road, there will be a setting to go back to solved puzzles/restart the progress. On the other hand, it's free so expectations for greater customization are rather low.

Goals we can target in Tx with this app: Language goals that involve word-finding and naming are addressed rather straightforwardly, but there's also good use of repetition and Q/A that can be useful in addressing apraxia and dysarthria goals. Describing and discussing the 4 pictures presents a great opportunity to practice verbal expression. Reasoning is addressed with solving the puzzles, and focus/attention can be addressed as well (presenting 4 different pictures to solve for one word would require some cuing for focus for quite a few of my current clients). A client with lateral neglect may benefit from having to give equal attention to all 4 pictures to solve the puzzle. And you can always address memory goals with recall of pictures.

Some specific examples: Just a couple of examples of the less straightforward uses of the puzzle.

1. Memory goals: after discussing each of the 4 pictures and, hopefully, solving the puzzle, turn off the device and recall the 4 images. Start by cuing with the common word, then provide additional cues as needed.

2. Homographs/homonyms: address the various meanings of the target words as they come up in the puzzle. Since it will be as part of the puzzle-solving activity, and since the differing meanings of the words are in most cases what make the puzzle (e.g., in the screen shot above the actual taste of something vs. a synonym for "cute"), you'll have a great opportunity for this type of activity in  context (rather than a rote list of words as part of a structured task).

iPad app: Kokako 123 Audio and Visual Training

Kokako 123 App
Kokako 123 Audio and Visual Training app on iTunes (free)

What it is: Described as a game to "help auditory/visual training". This app's description on iTunes specifies that it is not intended to replace therapy, but to go hand in hand with it by providing repetitive practice to enhance skills. It definitely is targeted at children, but manageably so.

The game only does one thing: it gives a series of cards with numbers one at a time (see screen image 1) and asks the user to repeat them by using the keypad to enter each number below its card. One of the best things about it is that the user can choose what order to put the numbers in (same order they were presented from left to right, or backwards from right to left, or random).

Screen Image 1
Settings for this game include choices for how many cards will be presented (from 1 to 8; the example in the screen shots has 4 cards), and for how to present the cards (visually by flipping them over, auditory presentation where you can choose one of two male voices, or both visual and auditory). There is also a setting for how much time to space in ms between cards as they are presented.

Screen Image 2
Once user puts in the sequence and presses "go" feedback re accuracy is presented. As you can see in screen image 2, feedback includes which cards were correct, how long the turn took, and a count of how many turns were correct (screen shot 2 says "0" because not all 4 numbers were correct).

The themes are rather childish (you can choose car, flower or star; I have it set to the least annoying star) and there's a happy or sad star that comes up at the end of each turn. Not overwhelming, but nevertheless, it's there.

How we can use it in Tx: Set the activity to fit your client's needs in terms of how many numbers to remember (start with 3, and increase complexity to 4, 5 or even 6 if you think it's appropriate for your client's level).

Depending on the goals decide if you want the target number list presented orally or visually, and how fast. Maybe you'd like to have the client repeat each number as it is presented? That's a good memory strategy, and if you decide to go that path you may want to put in a longer delay between cards. Then have the client either tell you the sequence to enter or, if they have the dexterity, have them enter the numbers using the keypad.

What's nice is that you can also use this as a memory/mental manipulation activity and ask for the sequence backwards (since you can enter the answer in any order you want). You could also ask for the number sequence to be repeated in ascending or descending order. If you have the capability, you can enter the numbers in their correct spots; otherwise you can just enter the numbers in ascending or descending order and not worry about the game telling you the answer is incorrect--since it will flip the cards over at the end you'll be able to check accuracy that all numbers were recalled.

Goals we can target in Tx with this app: You can customize the settings and activity to target memory, immediate recall, spaced recall, working memory, attention,  and visual & auditory processing to a lesser extent.

Some specific examples:

The memory and attention activities are limited to numbers which is rather rote, so you don't want to spend too much time doing only this activity, but it can be useful for a short task or two.

1. As I mention above, if you want to work on memory and mental manipulation you can ask for the sequence of numbers to be given backwards or in ascending or descending order. If you ask for the numbers in reverse order, you can just enter them in reverse order and let the app tell you how accurate you were. If you do ascending or descending, you can just ignore the app's feedback on accuracy (since the game expects the numbers to be entered in their correct spots, not just be the correct ones) and judge for yourself when the cards are turned over whether all the numbers presented are accounted for. Should be just as effective and simple enough (except for the frowny star that will show up).

2. For spaced retrieval: you would think that you'd be able to use the running timer on the screen during the turn to space out input from output, but in fact this timer doesn't run during the turn--it merely returns the total time it took once the turn is over (and "go" is pressed). So you'll need your own watch/timer to space out this task. But otherwise, it's doable (although frankly, I'm not a fan of doing context-free numbers in this sort of activity).

3. If you are not working on mental manipulation that involves returning the numbers in a specific sequence, you can--like advised in #1 above--just ignore the accuracy of the order of the replies, and focus only on whether the client remembered all the items on the list. Again, you would not use the game's accuracy feedback for this and just keep track of it separately.

4. Brain-training: for the regular (not rehab-patient) population, this game can provide great training for memory and focus. Since you can set the game to provide you with a sequence of up to 8 numbers, with very little delay between them, visual or read, you can really set the task up to challenge anyone's function. You can also make yourself give the numbers back in ascending or descending sequence while getting them in their correct slots. And you can motivate yourself to return the answer faster each time as well.

iPad app: ScrapPad - Scrapbook for iPad (for sequencing)

ScrapPad App
ScrapPad - Scrapbook for iPad on iTunes (free!)

What it is: A sophisticated easy to use, and fun, scrapbooking application. It provides a variety of backgrounds, borders, embellishments and stickers (organized by themes like holidays, seasons, etc.). You can import images from your album (or take new ones from within the app with your camera), resize, move and rotate them however you want (except cropping--I didn't see that capability in the app; but there's native cropping in iOS already).

The app responds very smoothly to repositioning, rotating and resizing elements. You can work on the canvass with the tools at your ready or in full screen mode taking advantage of more space.

When you've made your creation you can email it, save (I'm assuming each page separately) to your album, share on FB, or send it to the app publishers to print (for a fee of course). They do not include the option to save your creation as PDF or some other format that can be read in iBooks, which is too bad for the scrapbooker, but not a big deal for our uses.

Screen Image 1
How we can use it in Tx: One obvious use for this app is to create family albums, logs, memory books and the like (much like what I wrote about in my review of My Story from 3/3/2012). I won't elaborate on that idea as it's fairly intuitive. My more interesting idea for this app though, is to use it for sequencing.

There's a few apps out there that are dedicated to sequencing tasks, where a user is presented with 3-6 step common tasks, with an image for each step, and asked to put the steps in sequence. I haven't seen any free apps for this, but here's a review from "Speaking of Apps" of a $4.99 app dedicated to sequencing called Making Sequences. It sounds great and the price tag is not too bad for a Tx-dedicated app. But it only comes with 15 sequences.

So here's what I did. I created my own sequence photos. For this review I very quickly made 2 sets of 3-step tasks (one making the bed, another folding laundry). I could have just as easily downloaded clipart. I put both of my tasks together to simulate what the screen would look like with a 6-step task (but if I was using each of these I'd have only the 3 steps of each task on the screen at a time).

I added all 6 photos to my scrapPad canvass, resized them for best fit and rotated them for proper aspect. I switched to full screen mode and basically created a space where the photos can smoothly be moved around as needed (see Screen Image 1). And there you have it: a sequence task. The reason it works so well is that (1) you can use the full screen so there's no dedicated sequencing app out there that can beat the real estate available for the task; and (2) the dragging/placing of the elements (the single photos) is so very smooth. They don't "snap to", but neither do photo cards you would use for this task if you didn't have an electronic version. There's also no music, no grading, no animation. It's just an improvement on the low-tech version in the sense that it's a lot easier to quickly make new sequences, and if you want, you can make them with images from the client's immediate environment.

Screen Image 2
One can make a page for each task, and create a "scrapbook" with as many sequencing tasks as they bother making with no limits. You can size the images to your liking (I wanted to make them as large as possible while still having enough room to move them around). You can also add titles to each page (if you want to add context; I like to ask my pts what the task is before they start sequencing, but some need the context to perform the task).

Just to show the full potential of this app (so well beyond what I'd use it for) here's a scrapbooked (albeit hideously... I'm not much for scrapbooking) version of my 6 pictures on the canvass with the tools open, and the "export" window open so you can see the options it comes with (Screen Image 2).

Goals we can target in Tx with this app: Memory/STM and orientation goals (which I didn't discuss much but they are fairly obvious), focus and direction following, spatial reasoning if you want to do some actual scrap-booking tasks, and the one I suggest it for: sequencing and sorting.

Some specific examples:

1) For sequencing--the main use of this app I recommend--snap some photos of common daily activities, even specific activities of your client if you feel it's appropriate, import them into the app and size them so all steps of the sequenced task can fit, then move to full screen and let the client order the steps. Just as I describe above. There's really no end to the possibilities.

2) For sorting, download or snap photos of elements you can sort (items or animals that vary in size or number, people that vary in age, foods that vary in size or calories, whatever you can think of... just keep it clear) and create a task just like the sequencing one. Save these and over time you'll have a ton of fun sequencing and sorting activities in one place.

3) A fun STM task that allows for use of memory strategies is to create a page for a specific event or season (e.g., for Easter or a birthday). Create it with the pt, discussing the various elements you're putting in there and color decisions, etc.; make all decisions explicit and together. Then find some filler task you can do for 5-10min (whatever you think is appropriate) and return to this task: ask for recall of the creation you made together, and carefully use cues as needed to get as much recall as possible (cues can range from visual to discussing some of the decisions you made together, etc.).

iOS/Android App: Counting Dots

Counting Dots App
Counting Dots on iTunes ($0.99)
There's also a version for Androids on Google Play (same price)

What it is: It is described as a colorful counting game for kids. The colors are vibrant but crisp and clean (if nobody told me it was for children, I'd just think of the layout as modern). Popping sounds and vibrations can be shut off as well. The task is one of counting, where you can count by 1's, 5's or 10's, and you can start with any number you choose (so if you start with "5" and count by 5's you'll get 5, 10, 15, 20, etc, just like in the screen image below; and if you start with "2" and count by 5's you'll get 2, 7, 12, 17, etc.).

A player is presented with dots in various colors and sizes with numbers on them, and the task is to select them in ascending order. The game playing happens in levels of increasing number of dots. First you're given one dot. When you clear that (by selecting the one dot) you are given 2 dots. When you clear those, you are presented with 3, and so on.

The background colors and dot colors are different each turn. The dots overlap, but the correct answer is always visible (though sometimes hidden by the previous answer). The sizes vary randomly (so 80 may be tiny and 85 large; but all fully legible and selectable). If you touch the wrong dot it shakes for a split second, nothing else happens. So there's no error reporting, there's no scoring and as far as I can tell, there's no end.

How we can use it in Tx: I'd shut off sounds and vibrations in the settings, and set the difficult appropriately for each client. Here's my opinion of settings ranging from easiest to most complex given the parameters of this app:

1. Starting with 1 or any number, and counting by 1's (1, 2, 3, 4, etc.)
2. Counting by 10's, starting with 10 (10, 20, 30, 40, etc.)
3. Counting by 5's starting with 5 (5, 10, 15, 20, 25, etc.)
4. Counting by 10's starting with something other than 10, for example 3 (3, 13, 23, 33, etc.)
5. Counting by 5's starting with any number between 1 and 4, for example 2 (2, 7, 12, 17, etc.)

Using an iPad with its larger screen is probably best. Ask the patient to perform the task (select the dots in ascending order, with a greater number of dots presented each after the previous one is cleared). You can keep track of accuracy by counting errors (error stats, as I mention above, are not kept; but the incorrectly pressed dot does shake for a split second providing a quick but not distracting or discouraging visual of an error if a therapist is watching for it). Maybe stop the game either after a certain time limit (play it for 5 minutes, for example, and note how many levels have been achieved in that time) or after the pt seems to get stuck a lot (hits the wrong dot several turns in a row). Definitely try to stop before frustration sets in, but do try to get to a level that is challenging for your client.

Goals we can target with this app: Sequencing obviously, providing a range of difficulty levels for this task. Certainly math (on the simpler level, although you'd be surprised how challenging it can be to sort the dots in ascending order as you get into the higher numbers). Memory (STM, working-memory) are addressed: it is actually pretty challenging to remember where you are in the sequence once you've been playing for a while, especially with distraction of colors and sizes of the dots. Visual field neglect and scanning are incorporated as the dots are spread across the screen, and again, the colors and sizes can provide competing stim. And if there's competing stim, focus and attention play a role as well as direction following. I wouldn't spend too long on this task, but it's a nice 5 minute exercise that can address a number of goals.

Some specific examples (or in this case, rather, just notes):

1. If you are working on memory goals, then note the fluency with which the sequence is carried out. That is, to play this game smoothly the player must remember what number they are on. If, however, they forget, they can still carry the task out by scanning the screen and finding the smallest number to select. So it would be up to us to see which strategy is being used.

2. If you are working on visual neglect or scanning, note accuracy involving the weaker side compared to the stronger.

3. Patients with focus goals will probably be most distracted by size differences between the dots. You may also want to add another layer to the task, where if a smaller number has a larger circle your client must somehow acknowledge it (verbally, for example) which will provide a divided attention aspect to the exercise.

4. For a reasoning/problem-solving (and math) goal you could set up the starting number and intervals, and let the client start playing with the goal of figuring out what the sequence is counted by (1, 5, or 10). Difficulty levels for this type of exercise are similar to those listed above, although it is fairly limited in that respect.

iPad App: A Memory Game

A Memory Game App
A Memory Game on iTunes (free)

What it is: Basic memory/concentration game where you start with 20 "face down" cards, and picking 2 at a time try to match pairs. When pairs are found, they are removed from the board. It is one of the few memory/concentration game apps I've found that is not targeted at children with cute pictures of animals and such. The images are crisp and clear and definitely favor adults. There's no distractions such as unnecessary animation. Very basic, very clean, and I can't believe it's free!

Screen image 1: playing with flags
You can play the game using flags or symbols. The first is flags of countries where the card shows both the flag and the name of the country (see screen image 1). Symbols are black and white simple images such as pencil, flower, airplane, etc. (see screen image 2); they are all very clear and easy to tell apart, but there is no text or color.

As you play the game keeps track of your tries and how many pairs have been cleared. At the end of a game you're presented with a message that tells you how many moves it took you to clear the board.

How we can use it in Tx: Obviously the way to use it is let your client play this game. I would consider the flags option as the more basic, easier, level. Flag images come with context: the name of the country is provided which gives a player something to hold on to in memory. There's also colors that help visually distinguish each card. The symbols option is definitely more complex as there is no text, and there are no colors. A player would have to name the image and hold on to just that word and location to continue matching.

Screen image 2: playing with symbols
The flag option provides you with plenty of opportunity not only for various cuing levels, but also to practice various memory strategies. As a card is opened the flag and country that is presented can be discussed. What do you know about that country? What continent is it in? Are you familiar with that region? Have you ever been there or wanted to go there? Did you recognize the flag? Do you like the colors of the particular flag? And references can be made to the location of the card itself (e.g., this country is a southern country, and hey, it's at the top of our board... it should have been at the bottom). OK, I'm reaching here, but my point is that this simple set of images presents us with lots of opportunities to model and practice memory strategies.

Goals we can target with this app: Memory (STM and to an extent working memory) obviously; certainly some scanning/visual field neglect. Focus/attention and following directions, as well as categorizing to an extent as part of flag/country discussion.

Some specific examples: I don't know that specific examples are needed in this case: just play the game using flags option, and decide on the level of cuing you want to provide. If you are targeting specific memory strategies (like repeating or visualizing) you can write goals for implementing those strategies while playing this game. And you can use the stats provided at the end if you want to help you measure accuracy and progress.

Brain-training: For the regular (not rehab-patient) population, this game can provide great training for memory. If you want it more challenging, certainly use the symbols option over the flag one. On the other hand, with just 20 cards, this will never get TOO challenging, just fun.

iPad/iPhone App: NumberOne Brain

NumberOne Brain app
NumberOne Brain app on iTunes (free)

What it is: A matching game where you are asked to locate a target number on a board tiled with several numbers (5-10 of them, see screen image #1). Very simple, but it gets more and more complex as you play: you have to learn to ignore competing stim to find the number you need.

Screen Image #1
As you can see from the screen image at a maximally simple point in the game (the start), the tiles are spaced so there's only one per column. Visual complexity is increased by adding more tiles to choose from, and/or lining them up to have more than one per column. Also, proximity of visually similar number tiles (to the target number) can add complexity, as can the extent of similarity between the tiles (so instead of maximally different from the target number as in the screen image, you may get 101, 110, 1, 211 and 11). The colors of the tiles may also work to draw your attention away from the correct answer, and at a more difficult level an incorrect tile may compete for your attention by shaking a bit. Possibly there's something in the sound as well, but I never play games like this with sound on. Either way, this is a great way to exercise your focus and quite fun as well.

Screen Image #2
How we can use it in Tx: There are several difficulty options available for this game, and as usual I recommend the simplest: "easy". All game play gets more complicated the better you do during the round though. Also, as usual I recommend playing this without the sound unless you have a pt with very high fxn that could use the extra competing stim.

One thing to keep in mind about this game is that, although a fairly simple concept and pretty fun to play, it is timed and graded, although as of March 2013 the grading can be turned off per new update. A round lasts a certain length, and you lose seconds when making mistakes, and I think gain some if have a good run. Here's an example of the summary that shows up at the end of a round if grading is not turned off (screen image #2). Some of the data is worth having, and may even be useful to us for keeping track of progress. However, the school-like grading of "brain level" is not for use in therapy (the original version of this app I reviewed did not allow grading to be switched off, and that's where the screen image is from). The new version does allow you to avoid this grading, which is a huge bonus for our uses! A great thank you to the developers for this, and their update re the matter on this post!

Goals we can target with this app: Attention, focus, following directions, scanning and visual field neglect goals, and of course memory goals (I suggest a way to focus on memory below). A pt with severe symbolic dysfunction may benefit from number matching as well, but they may need too much time for each match to get any real use out of this game. Worth a try.

Some specific examples: There's not really a lot of things you can vary in playing this game. You can vary the level of cues provided to help pt find matching tiles, and you can focus on specific results and/or progress. So for example:

1. If you're working on scanning and field neglect then accuracy becomes an important goal, and you should consider the number of mistakes per round. However, you should also pay attention to how many of those mistakes were due to competing stim from the dominant side.

2. If you're working on focus/attention, pay closer attention to what kind of competing stim interfered most (was it color, was it motion, was it placement, etc.).

3. Here's an idea for how to work on memory goals: Every time a new target number appears, after the pt has looked at it, pause the game (the screen will turn black, covering up the playing board). Check for immediate recall of the target number. If appropriate, distract the pt with something and then check for delayed recall. Then go back to the board, let the pt find the match, and do the same for the next target number (or skip one or two numbers, then pause for the following one to check recall). If you want to up the difficulty, upon pause ask to recall the current target number and the previous one.

4. Brain-training: for the regular (not rehab-patient) population, this game can provide great training for attention and focus, reflexes, scanning, and to some extent memory. For this population the graded summary may be a great motivator to do better each time you play.

iPhone/iPad app: Speed Match

Speed Match App
Speed Match on iTunes ($0.99, sometimes free)

What it is: a game where you are presented with two columns of 5 icons, and you have to remove them by matching icons from each column. Sometimes there's a few icons that are the same in both columns, sometimes only one (as in the screen shot here). Once you've matched and removed all the icons you win the round.

While playing, you can swipe a tile off the board from either column as needed, and these tiles are replaced by different ones. There is no "punishment" for doing this except for wasting time if you do it too often. There are no untimed rounds, sadly. There are several levels: you get the same total time to complete the rounds (4 minutes) and with each level you have a larger number of tiles to clear. The easiest is 25 tiles, then 50, 100, 125 and 150.

Screen Shot
As I mentioned already, all levels are timed. Additional challenges include that you can only mismatch 3 times (see 1 of the 3 spaces under the time left in the screen shot is lit up); once you mismatch 3 times the round ends. Waiting too long between matches will also cost a "mismatch" light. There are also several selections of tile styles, but I think the ones in the screen shot (the default ones) are probably easiest.

One other thing: this game is optimized for the iPhone/iPod screen sizes, but works really well in x2 mode on the iPad. I recommend only using the larger iPad screen in Tx.

How we can use it in Tx: I have written the developers and asked if they'd consider adding an untimed mode that could be used for practice or younger players in general, and our target population in particular. But until such a mode is added, I envision using the easiest level (matching 25 tiles) and setting realistic goals of how many tiles to remove before the clock runs out rather than expecting a pt to clear the board completely. You can vary the level of support provided to reach the goal. You can also make it maximally simple by finding a match yourself, and then touching the pair-able tile on one side, and asking the pt to find that tile on the other side. But remember, to play this you can't select tiles, you have to be actively/continuously touching both at the same time (however, you can be touching one side and take time before touching the other side; the tile will be removed once both sides are touched).

Goals we can target with this app: attention and focus, following directions, problem solving, scanning and visual field neglect, and of course memory.

Some specific examples:

1. For memory goals, the therapist can find a pair-able tile, bring it to the pt's attention and ask for the pair, then cover the tile up (thereby "selecting" the tile by touching it, so when the paired tile is touched it is removed) for the pt to find the matching tile from memory. Set a goal for how many tiles you want matched before the round ends (either due to time running out or 3 errors).

2. For visual field neglect just playing this game and having to simultaneously touch tiles from both sides is a great activity. A variation could be having the ST find the pairs and, like in #1 above, pointing out a tile on the pt's stronger visual side (but not covering it up like in #1, just pointing at it) and having the pt find the corresponding tile on the neglected side.

3. To target problem solving make a goal that involves removing unmatchable tiles while looking for matches. For example, tell the pt to remove 2 tiles they consider in their way every time they are stuck looking for a match. On the go reasoning is required to make these decisions (play the game for a bit and you'll see yourself).

4. To target direction following the ST, again, can be the one locating the matches, and communicating which tiles to touch to the pt. This information can be communicated by describing the tile (shape, color) or their location in the column (at the very top, halfway down, etc.) or both. This will take quite a bit of time so don't expect to clear too many tiles before time runs out. Maybe if an untimed mode is added.... :-)

4. Brain-training: for the regular (not rehab-patient) population, this game can provide great stimulation for attention/focus, memory, reflexes, scanning, decision-making and prioritizing. It's kind of addicting, but for short bursts of game playing (not one of those games you'll find yourself wasting your whole day on).

iPad/iPhone App: NxtApp

NxtApp App
NxtApp on iTunes ($0.99, free sometimes)

What it is: A mental math puzzle where you have to find the next number in a sequence using basic math. For example, you may get the following screen: 5, 8, 11, 14, ___ and you have to solve for the missing number. Using simple math (in this case addition) and logic you deduce that the missing number is 17 (each number is the sum of the previous number + 3). The missing number in the sequence is not always the final one, it can be any of the numbers.

In each round you get 10 sequences to solve, although instead of just counting how many you solved correctly (which would have been much better) the round stops with the first error. But it lets you restart the round immediately so it's not a huge problem... it just means that if you want an accuracy % you'll need to keep track manually. There is a timer that runs while the sequence is being solved, but thankfully there does not appear to be a limit to how long one takes.
 
There are several categories of level difficulty: The first listed is "beginner" but it's actually a link to a different app from the same seller, intended for kids. The next level is called category 1, and it includes additions (+) and subtractions (-), category 2 multiplications (x) and divisions (÷), category 3 can have x, + or -, category 4 has powers, +, and -, category 5 has powers and x, category 6 is more powers and 7 is mystery. So as you can tell, the task gets more complex with each category.

How we can use it in Tx: When it's a game like this, simply have your pt play the game and adjust your cuing as needed. For most pts the most appropriate category would probably be 1 (limited to + and - math operations). For most pts when the operation that makes the sequence is adding or subtracting more than single digits (for example a sequence such as 2, 13, 24, 35 where each number is the previous + 11) they may need a pen and paper to calculate. And pts with reasoning goals may need additional cuing to determine what to calculate (to subtract the preceding number from the one that follows it).

Goals we can target with this app: Problem-solving, reasoning and specifically math goals, obviously sequencing goals, direction following and focus (focusing on a math problem in competing noise is quite the task), and of course memory--especially working memory--if the pt can do at least some of the task in their head (thereby having to retain the numbers and operations in memory).

Some specific examples:

1. For memory goals, play this game with the therapist looking at the screen and the pt having to solve the sequence either mentally or (more likely since some of the operations are a little harder) by writing the sequences down but from memory. That is, open a new sequence problem and read it to the pt all at once ("5, 8, 11, blank, 17"). The pt then has to remember all 5 numbers and repeat them before writing them down. If the pt couldn't repeat the sequence correctly immediately after it's read out, the therapist can read it again, and the pt can repeat it again. Repeat as needed until the correct sequence is repeated back, and then have the pt write it down. You can vary this task and make it easier by only reading out 3 or 4 numbers at a time. This way you are working on retaining lists of numbers (and subsequently writing them down) as part of a larger task making the list-repeating feel a little less rote.

2. For reasoning, sequencing and math goals simply play the game and choose the level of cuing your pt needs. The math required to solve each puzzle is fairly basic, but the logic and reasoning skills to figure out how to solve it may be rather difficult for many of our pts. Whichever of these goals is yours, pay attention to the cuing needed for that specific skill (i.e., your pt may need max cues to figure out which numbers to subtract or add to figure out the answer, and what to do with the answer when it's figured out, but may be able to independently carry out the actual math operation once it's determined).

3. Brain-training: for the regular (not rehab-patient) population, this is a great math and logic puzzle to train your mental math abilities. Try to beat the clock and do it quickly or aim for accuracy over speed.

iPad/iPhone app: Writers App

Writers App
"Writers App" app in iTunes (usually $0.99, sometimes free)

What it is: An application to help authors plan a story/novel. A place to enter notes about characters, places, the plot, individual chapters, etc., and to keep it in an organized database. It is very intuitive to use, and does not require each field to have content.

You start out by adding a story (you can work on several at once, each with its own entry). For each story you then add relevant details: a title, information about the story (synopsis, premise, plot), chapters, characters, places, and there's room for further notes. You can add as many characters (or chapters, or places) as you want. For each character there are fields for name, general info (role, occupation), attributes such as strengths and weaknesses, habits, biography, hobbies, personality, and physical characteristics (hair, age, eyes, etc.), and of course further notes. Each entry for "Places" also expands to the name of place, about it, environment, description, characteristics and further notes.

So as you can see, it's structured but has a lot of fields and room for freestyle notes. There's no customization for the fields (I'm sure future updates will include this; it is always something users request once they start using an app like this). There's also no way to include pictures, and I'm not sure there ever will be, but if needed that can be added via export: Currently there's only one way to export, which is to email yourself the list: whatever level you export from, will include the info on that level and below it. So if you export from one character's view, you will only get the info for that character; if you export from the main story level, you will get everything you have entered for the entire story (all the characters, places, etc.). The emailed text can be copied and pasted into a simple document, and if needed pictures can be added. Format nicely and print.

How we can use it in Tx: This is a great tool to keep track of characters and plot twists for an author in the planning stages of their great novel... And for us, it's a great tool to help pts slowly put together their own life story. While there are a few fields in this application that won't play a role (and may confuse a pt if they are doing this independently) I think this is a great tool to use *with* the SLP to work on reminiscing, map out one's family members, one's life story, and even better--all of these. Since the information is so well fragmented into characters, places, story... we can concentrate on one section at a time (for several sessions, as needed). And the best part is that the resulting information from these sessions can be printed for the patient to keep.

This may not be the perfect app for doing this, but it's a nice start. And it lets you keep a list of what the pt has already contributed, go over it in future sessions, and proceed from there. And of course this can also be achieved with just a pad and paper, or any number of note-taking apps (some that also allow pictures and sound attachments). But I like the organization of this one that makes this open-ended task into a structured exercise, easier to follow through with and to pick up where you left off in future sessions.

Goals we can target with this app: Memory goals mostly, and since it uses a pt's personal information about their life and family, one hopes there's increased motivation to participate in the task. Sequencing and categorization, attention and question/answer goals are addressed almost inherently as part of the task, and there could be added focus on these goals as needed. For example, a pt could be asked to recall something from grade school, something from high school, something from college (if they attended) or military service (or whatever else they did after HS) and work on sequencing these stories into chapters (which came first in life, which later). Orientation is also addressed as part of discussing previous events, younger age, different locations (that was then, this is now).

Some specific examples:

1. Reminiscing: for a pt that isn't able to remember a lot about their own life, you can create a chapter for certain decades (20's, 30's, 40's, 50's, 60's...) and think of famous characters from each era (Marilyn Monroe, Shirley Temple, Churchill, Charlie Chaplin, etc.). and famous events... If you don't remember much from your grade school history classes you can do some minimal research online and find enough famous events and people for each decade within minutes, surely. Or you can do the research together with your pt, and let them participate and recall some of these milestones. I had a pt who had a really hard time remembering anything about his own life, with LTM and STM goals. I brought in a reminiscing task with pictures of famous events or people from various decades, and we went through them. My pt said he won't remember any of it when we started, but as we went through my list he did in fact recall quite a few of the events and people, and had a few bits of information to contribute about them, some even from personal experiences. It was a very successful session that left both of us smiling.

2. External memory cues: work on a pt's family tree using this app by adding each family member as their own character. Go over each character on multiple occasions trying to get pt to recall additional attributes; maybe add descriptions based on photos in the pt's room... You can get additional info from visiting family members if possible. Just have fun with it. And this is certainly something you will want to export, format, and print for the pt when you are done.

3. Write a pt's life story, especially if it's a pt who has lived in several places. Write a chapter for each time in their life (as I mention above, one for grade school, one for high school, etc.) and again, let them fill in bits and pieces over several sessions (give the specifics recalled previously and ask for more detailed info, e.g. "so last time we talked about your time in the army and you mentioned you were stationed in Italy. How long were you there?").

iPad/iPhone app: Match Panic

Match Panic app
Match Panic app in iTunes (was free for a while, now $1.99)

What it is: It is a matching game, where various tiles queue up in the middle of the screen, and you tap the right or the left to match them. Each level starts with just two tile images (see screen image #1), and every two levels or so one more is added at some point in the level (see screen image #2). It is timed, so if you don't finish a level in 30 seconds, you get a score but you don't move up to the next level (that is the only consequence). If a tile is matched to the wrong side, it turns into a sad face for a second (and costs a second of your allotted time).

Screen image #1
There's powerups too, which may add or reduce complexity of the task as they may affect the queue, e.g., by turning all visible tiles to the same shape, or "blowing up" the next few tiles in the queue, reducing the number of total tiles to be matched for that level. Powerups are a reward for a high scoring round, so a slow player isn't going to encounter this complication often. Don't let the "panic" in the app's name fool you: it's only panicky if you are gung ho about moving up levels and matching quickly. If you're playing the game in a more casual manner, there's nothing in particular that rushes you (other than the fact that the timer may run out before the level is finished, but if your goal is to play one level, no big).

Screen image #2
How we can use it in Tx: Pretty much assume you will only use the first 1-4 levels of this game, although there's nothing specific you have to do to select this. Just keep the goals simple. Turn off the sound so there's no "countdown" sound at the end of a level, and trust me, the music is super annoying anyway. It is designed to make the game feel more urgent (gives it that "panicky" flare) so it's best avoided.

This type of visual matching to right/left is a fairly good exercise for lateral neglect issues. This task is very similar to some divided attention activities that involve canceling a specific word or letter from a pageful of words/letters. Following directions is built-in, and memory plays a role as matching is easiest if one remembers the tiles on each side instead of having to compare each tile. As the number of tile shapes increases, so does the complexity of each of these tasks, including memory.

Goals we can target in Tx with this app: Following directions, sequencing, sorting, focus/attention, divided attention, scanning, visual neglect, and of course memory. This is also a great app for brain-training for the general population.

Some specific examples: Although this is a simple one-dimensional activity, I think it can be used in a variety of ways for different fxn levels and goals. Here are some examples.

1. For a slow, focused approach, possibly for a lower-fxn pt, prioritize accuracy of matching rather than total tiles matched, and ask the pt to take their time but send the fewest possible tiles to the wrong side. Let the progress be as slow as it needs to be, and set as goal for the task a limited number of tiles (10 or 20, for example). Have the pt count out each tile that is matched, and keep track of how many were initially matched incorrectly (then you can calculate % accuracy easily).

2. For a more advanced pt you can prioritize overall completion: Don't count how many were matched incorrectly (although that will play a role as each incorrect match reduces the level's time) and ask the pt to go through as much of the queue as possible in the allotted time. Calculate accuracy by points scored (since it's difficult to calculate percent of queue completed--you only see a piece of the queue at a time with no hint as to how much of it is still to come; if they ever add a % completed counter to this game it would be even better for Tx).

3. For visual neglect goals prioritize the neglected side, and ask the pt to say out loud the tile on that side each time it is encountered. So for example, focusing on the left side of the level in Screen image #1, each time a cactus is encountered have the pt say "cactus" before touching the left side. That way, not only is matching required on the weaker side, but it's also emphasized verbally.

4. Brain-training: This app is also great for normally (or close to normally) functioning individuals who want to get some cognitive training. This kind of thing is now popular with sites such as Lumosity, with more popping up. Everyone wants a piece of this neuroplasticity performance training. And if you feel the need for brain training, an app like this matching one will certainly do the trick as an attention-enhancing activity much like those offered on the paid "brain training" sites.
