    Stroop Test

    The Stroop effect (1935) demonstrates interference when the name of a color word differs from the ink color. It is a familiar format for inhibition and cognitive-flexibility tasks. Parameters adjust to the level and the task.

    Task focus

    Each task format is associated with these cognitive categories:

    inhibition

    Ability to suppress automatic or dominant responses, impulses, and irrelevant information.

    cognitive flexibility

    Ability to switch between tasks, rules, and strategies depending on context.

    processing speed

    Pace of perceiving, analyzing, and responding to incoming information.

    How to use it

    1. 1Open the exercise and adjust the difficulty to the student's current level — usually it is better to start slightly easier than feels right.
    2. 2Read the rules. They are short, usually 10–20 seconds.
    3. 3Use the generated task as structured educational material, with accuracy and clarity prioritized over speed.
    4. 4Compare the answer with the reference and leave a human-written comment if the task is assigned through the student cabinet.

    Who it's for

    • Educators and tutors — as material for lessons, review, and home practice.
    • Speech, special-education, and development specialists — for children and adults; parameters adjust to the student's level.
    • Parents — to receive clear assignments and leave comments about completion.
