How to Practice Each CogScreen Subtest: What Research Shows

TL;DR. Our own study of 342 pilots showed that practice improves scores, and that how much depends on the subtest. This article goes one level down: one technique for each of nine subtests, each tied to published cognitive research on that kind of task. None of these studies was run on the CogScreen-AE itself, so I will tell you what the research found, what I am inferring from it, and where the evidence stops. Four other subtests already have technique in our subtests guide.

Why Technique, and Why I Am Careful About It

When pilots ask me how to practice, the honest first answer is: more deliberately than you think. In our practice study the median gain for pilots who started below 85% ranged from about 20 points on Manikin to under 4 points on Math. Repetition alone does not explain a spread like that. The task matters, and so does what you do inside it.

I need to be straight with you about the evidence. To my knowledge there are no published trials of technique on the CogScreen-AE itself. What exists is decades of research on the task families its subtests belong to: symbol substitution, delayed matching, dual-task performance, melody memory, trail making, task switching, matrix reasoning and mental folding. That research is solid, and the step from it to your practice session is an inference. I will mark that step every time.

Nothing here is a way to game a test. A technique is a better way of doing the task the test is measuring. If you learn to keep a rule in mind, or to fold a shape in your head one crease at a time, you have improved the skill, which is the point of preparing.

The Short Version

Subtest	What mostly drives the score	One technique to practice	Research it rests on
Symbol Digit Coding	Speed, plus memory for the pairs	Learn a few pairs early so you look up less	Joy, Kaplan and Fein (2004)
Matching to Sample	Holding a visual pattern briefly	Name the pattern in a short phrase before it disappears	Souza and Skóra (2017)
Divided Attention and Dual Task	Sharing attention between two tasks	Practice with shifting emphasis, not always an even split	Kramer, Larish and Strayer (1995)
Auditory Sequence Comparison	Holding a tone sequence	Encode the shape of the sequence: up, up, down	Dowling (1978)
Pathfinder	Visual search, and on alternating boards, switching	Keep the sequence running in your head: 1, A, 2, B	Sánchez-Cubillo et al. (2009)
Shifting Attention	Noticing a rule change and letting go of the old rule	Say the current rule to yourself	Emerson and Miyake (2003)
Figure Analysis	Working out the rule of a matrix	Decide what the missing figure must be before looking at the options	Gonthier and Thomassin (2015)
Spatial Folding	Mental folding and unfolding	Unfold one crease at a time, in reverse order	Harris, Hirsh-Pasek and Newcombe (2013); Uttal et al. (2013)

Symbol Digit Coding: Learn the Key as You Go

What the research found. Symbol substitution looks like a pure speed task. Joy, Kaplan and Fein analyzed the standardization sample of the most widely used version and found that speed explains most of the score, and that memory for the symbol and digit pairs makes its own, separate contribution. People who learn the pairs as they work have to look up at the key less often.

What I infer. Every glance at the key costs time. If you deliberately commit two or three pairs to memory in the first few items, you buy back that time for the rest of the run. As our subtests guide describes, the official battery also comes back later and asks which pairs you remember, so learning them pays twice.

How to practice it. Three Symbol Digit Coding sessions a week, about ten minutes each. In each one, pick three pairs in the first fifteen seconds and learn them. Next session, add a fourth. Watch two numbers: your accuracy, and whether it holds as you speed up.

Matching to Sample: Give the Pattern a Name

What the research found. Souza and Skóra had people hold colors in mind for a moment and then reproduce them. When people named what they saw, their memory was better than when they were kept from using words. The label did not replace the visual memory. It added a second, categorical record beside it.

What I infer. That study used colors, not grid patterns, so this is an extension. The principle carries: a short verbal description gives you something to check your visual impression against. "L shape, top left, three dark" is enough.

How to practice it. Before the sample disappears, say your phrase silently. Keep it to the features that separate one pattern from another: shape, position, count. If your phrase takes longer than the sample is on screen, it is too long.

Divided Attention and Dual Task: Practice Shifting Emphasis

What the research found. Kramer, Larish and Strayer trained people on two tasks at once in two ways. One group was told to share attention evenly every time. The other practiced with shifting priorities: mostly task A for a while, then mostly task B, then both. The shifting group improved more, and they were better at coordinating the two tasks afterward.

What I infer. Splitting your attention exactly in half is not a skill. Controlling where it goes is. These are the two subtests closest to a busy cockpit, where you never share attention evenly: you fly first and talk second, and you keep both alive.

How to practice it. Across a week, run one session where you favor the tracking or monitoring task and simply keep the second task alive, one where you reverse that, and one where you try for both. On the day, do not abandon either task. A brief lapse on one costs less than dropping it.

Auditory Sequence Comparison: Hear the Shape

What the research found. Dowling's classic work on memory for melodies showed that people store a tune in two ways: the exact pitches, and the contour, which is the pattern of ups and downs. Contour is quick to grasp and sturdy over a short delay.

What I infer. When you compare two tone sequences, the contour is the first thing to check, because it is the cheapest to hold. It is also not enough by itself. Two sequences can rise and fall the same way and still differ in how far they move, and those are the items pilots miss.

How to practice it. For each first sequence, trace its shape: up, up, down, up. When the second plays, check the shape first. If the shapes match, ask whether any step sounded bigger or smaller. Use headphones and a quiet room every time, so you are practicing the task and not fighting the acoustics.

Pathfinder: Keep the Sequence Running

What the research found. Pathfinder belongs to the trail making family. Sánchez-Cubillo and colleagues took that family apart and found that the numbers-only version mainly reflects visual search speed, while the alternating version (1, A, 2, B) mainly reflects working memory and task switching.

What I infer. Those are two different jobs, and they deserve two different habits. On a numbers-only board your time goes into finding the next target, so keep your eyes moving ahead of your hand. On an alternating board your time goes into remembering what comes next, so keep the sequence running in inner speech: "three, C, four, D".

How to practice it. Response time, not accuracy, is what separates pilots on this subtest, because most pilots make few errors. Practice for a steady pace. A wrong connection costs far more time than a moment of care.

Shifting Attention: Say the Rule

What the research found. Emerson and Miyake asked people to switch between tasks while repeating a meaningless syllable aloud, which blocks inner speech. Switching got dramatically slower. Their conclusion was that people use inner speech as a self-cue, to call up the task they are about to do.

What I infer. On Shifting Attention the rule changes without warning, and the errors that hurt are the ones where you keep applying the old rule after the feedback has told you it is dead. A rule you are saying to yourself is a rule you can consciously replace.

How to practice it. Name the current rule silently as you sort: "color, color, color". The moment you are told you are wrong, stop, and name a different rule before your next response. Do not try the old rule one more time. After a session, look at what happened right after each rule change, not at your overall accuracy.

Figure Analysis: Decide Before You Look

What the research found. On matrix reasoning tasks people use one of two strategies. Some work out what the missing figure must be and then look for it among the options. Others look at the options and try to rule them out one by one. Gonthier and Thomassin showed that the first approach produces better performance, and that when everyone was steered toward it, the advantage of people with larger working memory shrank.

What I infer. This is the most direct piece of evidence in this article, because the task studied is the same kind of task. The options are distractors by design, and reading them first fills your head with wrong answers.

How to practice it. Cover the options with your hand if you need to. Read across the rows, then down the columns, and say what changes: "rotates a quarter turn, shading alternates". Decide what the missing figure looks like. Only then look for it. If it is not there, your rule is wrong, which is useful to know.

Spatial Folding: Unfold One Crease at a Time

What the research found. Harris, Hirsh-Pasek and Newcombe reviewed mental folding beside mental rotation and concluded that folding is its own skill: it transforms a shape in steps, one crease after another. Separately, Uttal and colleagues pooled 217 studies of spatial training and found that spatial skills improve with practice, that the improvement lasts, and that it transfers to spatial tasks that were not practiced.

What I infer. Two things. First, this is a subtest where practice should pay, and our own data agree: it showed one of the larger gains in our study. Second, because folding happens in steps, the reliable way to find where the holes end up is to undo the steps in reverse. Every unfold mirrors the holes across that crease. That part is geometry, not psychology.

How to practice it. Do not try to see the finished sheet in one leap. Undo the last fold first, mirror the hole across that crease, and count the holes you now have. Then the fold before it. Say the count at each step: one, two, four.

What To Do Next

1. Pick two subtests, not nine. Choose the two where your scores stand lowest, and practice one technique on each for a week.
2. Keep sessions short. Ten to fifteen minutes on one subtest, with the technique as the only goal of the session.
3. Judge by the right number. Accuracy for most subtests, response time for Pathfinder and Manikin. If accuracy dips while the level you reach rises, the items got harder, and that is progress.
4. Give it a week before you judge it. A new technique usually slows you down for a session or two.
5. Look after the basics. Sleep and nutrition move these scores more than any trick.

If you are a PilotPrep subscriber, your coach keeps a practice plan built from your own results and will tell you which two subtests to start with. It reads this article too.

What This Article Cannot Tell You

It cannot tell you how you will do on the evaluation, and neither can any preparation tool. It cannot tell you that these techniques have been tested on the CogScreen-AE, because they have not. And it is not medical advice. If you have a question about your own certification, that is a conversation for your AME.
