Measure task switching and cognitive flexibility. Follow the current rule: COLOR or SHAPE.
Tip: aim for clean accuracy first. Switch cost is computed from correct trials only.
Switch cost is the extra time (or errors) you typically show when you must change rules. In this test the rule alternates between COLOR and SHAPE, and your switch cost is estimated as median RT on switch trials minus median RT on repeat trials (correct trials only).

Most commonly: rushing, inconsistent key mapping, or distraction. Switch trials require reloading the rule, so accuracy-first usually improves both score and cost over time.
No. This is a simple cognitive task for self-tracking and practice. It does not diagnose any condition.
Yes. Keyboard/touch latency and browser timing can shift reaction times. For fair comparisons, track on the same device and browser.
