Online practice and general transfer
11,430 adults trained for six weeks: task performance improved without convincing general transfer. The study did not test BrainApps.

How can we distinguish improvement on an exercise from a change in cognitive skills? Explore the evidence and the classic tasks used in BrainApps.

01 / Research
Research needs to define the outcome in advance. Repeating an exercise, completing a similar task and applying a skill in daily life are different outcomes.
You complete a familiar exercise with the same rules and response format.
You perform a different task that uses similar processes.
You apply a skill in a different setting, such as learning or work.

Participants, training protocols and outcome measures shape each conclusion. These three studies ask different questions; their results cannot be combined into a single effectiveness percentage.

6meta-analyses
Six meta-analyses of varied interventions in healthy adults aged 18–55 found a small average working-memory benefit.

20years of follow-up
ACTIVE (65+) linked speed training with booster sessions to fewer dementia diagnoses. These findings do not establish effects of BrainApps.

This page brings together external research and explanations of our tasks. Our open Schulte and Stroop trainers show each attempt’s results and keep a history in your browser. These personal measurements help track practice; they are not a controlled study of the platform’s effectiveness.
Our methodology ↗03 / BRAINAPPS
BrainApps turns classic task principles into interactive exercises. Each has a specific rule and its own conditions for comparing performance.
Schulte tables and visual-search tasks ask you to find a target among other items. Grid size, mode and rules change the conditions.
Stroop puts word meaning and ink color in conflict. The flanker task places distracting items around the target.
N-back requires updating information; memory matrices and span tasks involve retaining locations and sequences.
The travelling-salesperson task requires route planning. Other reasoning tasks ask you to discover a rule or a missing element.
04 / Research
The open Schulte and Stroop trainers show the results of individual attempts. Compare the same settings, and consider speed alongside accuracy.
| Measure | What it means | How to compare |
|---|---|---|
| Completion or response time | Your search or response pace in a selected mode. | Keep the grid, rule and device the same; consider errors. |
| Accuracy and errors | How consistently you follow the rule. | Compare attempts with the same duration and difficulty. |
| Task difficulty | Grid size, task variant or memory load. | Compare results at one level before changing it. |
| History and consistency | When you practiced and how each attempt went. | Look at several attempts rather than one best score. |
05 / BRAINAPPS
A simple routine helps distinguish learning the rules from a sustained change in your performance.
Try Schulte tables ↗Use a familiarization attempt to understand the task and controls.
Choose one mode and difficulty. Use the same device and duration.
Track accuracy, time and difficulty. One good round does not establish a lasting improvement.
Transfer needs a different assessment. Use exam questions for exam readiness and the new task’s own measures for a new task.
Practice helps you learn a particular task. A conclusion about another skill depends on what was measured and how the result was compared.
A control group helps account for repeated testing and expectations. An independent task checks whether change extends beyond the familiar exercise.
No. Time, accuracy and points describe performance on a specific task. IQ uses separate standardized assessments with age-based norms.
The open Schulte and Stroop trainers save history in the current browser. Other BrainApps games and sections may follow separate storage rules.
