Build custom Stroop tests for your psychology research or classroom in minutes. Measure selective attention and cognitive control with millisecond-precise timing.
The Stroop Test, developed by John Ridley Stroop in 1935, is one of the most widely used cognitive assessments in psychology. It measures selective attention and cognitive control by presenting participants with color words printed in different ink colors.
The Stroop Effect occurs when the ink color conflicts with the word meaning (e.g., the word "RED" printed in blue ink). This conflict causes slower reaction times and more errors, revealing how our brain processes conflicting information.

The Stroop Test is a classic psychology experiment that measures selective attention and cognitive control. Participants must name the ink color of color words while ignoring the word meaning, revealing the Stroop Effect - the delay caused by conflicting information.
