Switch Challenge
Rapid-fire Stroop cognitive flexibility test: sort items according to dynamically shifting rules.
Launch Switch Challenge simulatorAdaptive staircase calibration
Difficulty scales dynamically from Level 1 to 25 based on response precision and speed. Correct answers advance difficulty (+1 level); mistakes drop difficulty (-1 level) to measure your cognitive ceiling.
Benchmark accuracy
Complete at least 6 questions in a full timed session with ≥75% accuracy to unlock higher difficulty baselines and persist high-water marks.
Assessment rules and guidelines
- 1A multi-attribute stimulus appears (shape, color, number).
- 2The rule banner at the top dictates how to sort (Color, Shape, Parity, Magnitude).
- 3Sort using Left/Right arrow keys or on-screen buttons.
- 4The staircase increases switch frequency on correct streaks and relaxes on mistakes.
Strategy and pacing
- Keep fingers rested on Left and Right arrow keys.
- Check the rule banner before looking at the stimulus.
