Cognitive Training Explained: Programs, Evidence and Plans
Cognitive training is structured, repeated practice on mental tasks, such as remembering sequences, switching between rules, or spotting patterns, with the goal of making your thinking sharper. The honest summary as of 2026: practice reliably makes you better at the exact tasks you practice, while evidence that those gains spill over into everyday life or general intelligence is thin. That does not make training pointless. It means the way you choose a program, and the goal you set for it, decides whether your time is well spent.
If you are comparing programs, thinking about a routine for yourself or a parent, or simply wondering whether the ads you keep seeing hold up, this guide walks through the main types of training, what review studies found, and how to build a simple plan you can stick with. It is general information for curious readers, not medical advice, and it cannot tell you anything about your own health.
What is cognitive training, exactly?
Cognitive training means deliberately practicing mental skills in a structured way, usually with a defined task, a difficulty level that adjusts as you improve, and repeated sessions over weeks or months. The idea borrows from physical training: if you lift weights, muscles grow, so if you drill attention or memory, those abilities should grow too. Whether the mental version works the same way is the central question, and it is why researchers keep a careful distinction between getting better at a task and getting better at thinking in general.
Three terms help you read any claim:
| Term | Plain meaning | Example |
|---|---|---|
| Trained-task gain | You improve at the exact exercise you practiced | Your score on a memory-grid game rises |
| Near transfer | You improve on a similar but different task | A different memory game also gets easier |
| Far transfer | You improve at something quite different | Better grades, faster work, or a higher score on a reasoning test |
Nearly every program can show trained-task gains, because practice does that. The valuable claims, and the hard ones to prove, sit in the last row. When a product says it will make you "sharper at work" or "protect your memory," it is claiming far transfer, so ask what evidence backs that specific claim.
The main types of cognitive training programs
Programs vary a lot in format, but most fall into a handful of families. Knowing the family tells you what the practice can and cannot do.
Computerized brain-training apps
These are the commercial products on your phone: short daily games built around memory, attention, speed, and flexibility. They are convenient and often well designed, and they adapt difficulty automatically. They are also the category you are most likely to see advertised. If you want a closer look at specific products and their trade-offs, see our guide to the best cognitive training apps.
Working-memory and speed-of-processing drills
Research programs often use focused tasks, such as holding items in mind while updating them, or reacting quickly to what appears on screen. They are the backbone of many app games. They produce clear improvement on the drill itself, which is exactly what makes them look impressive in a demo.
Strategy-based training
Instead of repeating a game, you learn techniques: organizing information into chunks, using mnemonics, or testing yourself on material you want to remember. Because you learn a method that applies to real material, this style can feel more useful in daily life than a game score.
Everyday and learning-based activity
Learning a language, an instrument, or a craft; solving crosswords or logic puzzles; reading demanding material. None of this is a branded program, yet it fits the definition of mentally demanding practice, and it comes with other benefits such as enjoyment and social contact.
What does the evidence actually say?
The most cited review is a 2016 paper by Daniel Simons and colleagues in Psychological Science in the Public Interest. The team examined 132 journal articles cited by brain-training proponents, along with studies cited on leading company websites. Their conclusions, as summarized by the Association for Psychological Science and the University of Illinois:
- Brain training appears to improve performance on the exact tasks people practice.
- Evidence of gains on closely related tasks is weak, and very limited for distantly related ones.
- There is minimal evidence that it improves everyday cognitive performance.
- Many of the studies had methodological problems, including small samples, weak control groups, and measuring many outcomes while reporting only a few significant ones.
Some studies had no control group at all, and others compared training with activities, such as crosswords or educational DVDs, that differed from it in other ways. The authors recommend better practices: preregistered studies, proper randomization, adequate sample sizes, corrections for multiple comparisons, and disclosure of conflicts of interest.
The review does not say that the brain cannot change or that mental activity is useless. It says the evidence for the specific, commercially marketed claims is not strong enough.

A warning about marketing claims
The gap between marketing and evidence has had legal consequences. In January 2016 the US Federal Trade Commission charged the creators of the Lumosity program with deceptive advertising. The agency alleged that the company claimed its games would improve performance at work and school, and would delay age-related decline or protect against conditions such as dementia, without adequate science behind those claims. The company agreed to pay $2 million to settle the charges, and a $50 million judgment was suspended because of its financial condition.
You do not need to distrust every program because of one case. But it is a useful reminder to read marketing the way you would read any health or performance claim:
- Look for the specific promise. "Fun puzzles" is a modest, honest claim. "Prevents decline" is not.
- Ask what was measured. Improvement on the product's own games is not the same as improvement in life.
- Check the comparison. Good studies compare against an active alternative, not against doing nothing.
- Watch the pricing. Read the billing terms and cancellation steps before you hand over a card.
How to build a cognitive training plan
Because the evidence favors specific, practical goals, the best plan starts with a question: what exactly do you want to get better at? A plan for remembering names looks different from a plan for staying mentally active in retirement or preparing for a timed reasoning test.
Step 1: Pick one target skill
Choose a skill you can describe in a sentence: remembering what you read, keeping focus for longer, solving pattern puzzles faster, or learning vocabulary in a new language. A narrow target lets you notice progress, and it matches what the research says training is good at.
Step 2: Match the method to the goal
| Goal | A sensible method |
|---|---|
| Remember material better | Self-testing, spaced review, and explaining ideas in your own words |
| Handle timed puzzles | Practice the puzzle format itself, then review mistakes |
| Stay mentally active | Mix new skills, reading, and social activities you enjoy |
| Try a gamified app | Treat it as entertainment and set a time cap |
The commentary published alongside the Simons review, by Jennifer McCabe, Thomas Redick and Randall Engle, points to lower-cost memory strategies with stronger research support, including self-testing, spaced study, and elaboration. These cost nothing and work on real material.
Step 3: Schedule it like any habit
Short, regular sessions are easier to sustain than occasional marathons. Set a fixed time for the session, keep it to a length you can manage, and track one simple number such as minutes practiced or items recalled. After a few weeks, check whether the target skill has improved in real life, not just in the practice exercise.
Step 4: Support the basics
Sleep, physical activity, and the rest of your routine shape how well you think on any given day. For a broader look at the habits and activities that matter, our guide to brain exercises for adults covers a practical routine.
Step 5: Review and adjust
If a program is not helping after a reasonable trial, switch methods or stop. Training is a tool, not an obligation.
Cognitive training and IQ scores
A common question is whether training raises IQ. Practicing a specific kind of puzzle will often raise your score on that kind of puzzle, which is a practice effect rather than proof of higher underlying ability. This is why a second sitting of the same test can look better without any change in how you think. If you want a one-time read on how you perform on reasoning questions, a single sitting of a properly structured test is more informative than repeated attempts. Keep in mind that an online test is a general snapshot, not a clinical assessment, and it cannot diagnose anything. If you have concerns about memory or thinking in yourself or someone close to you, a qualified health professional is the right person to ask.
Frequently asked questions
Q: What is cognitive training?
A: Cognitive training is structured, repeated practice of mental tasks to improve thinking skills. It ranges from phone games and research drills to strategy-based learning. People usually get better at the practiced tasks, while evidence for wider benefits is limited.
Q: Does cognitive training work?
A: It works for the task you practice, but broad benefits are unproven. A 2016 review of 132 journal articles cited by proponents found very little evidence of gains on distantly related tasks or everyday performance, and many studies had methodological weaknesses.
Q: Which cognitive training program is best?
A: The best program is the one that matches a specific goal and that you will actually keep doing. For remembering information, self-testing and spaced review have stronger research support than game scores. For enjoyment, an app can be a fine choice if you treat it as entertainment and check the billing terms.
Q: How long should I train each day?
A: There is no proven magic amount. Short, regular sessions you can sustain are a practical starting point. Track whether the skill you care about improves in real life, then adjust or stop if it does not.
Q: Can cognitive training prevent dementia?
A: No program has been shown to guarantee that, and ads claiming it have drawn regulatory action. In 2016 the FTC charged Lumosity's makers with deceptive advertising, including claims about delaying decline. For worries about memory, talk to a doctor rather than relying on a game.
