Create a Stroop Test Online

Build custom Stroop tests for your psychology research or classroom in minutes. Measure selective attention and cognitive control with millisecond-precise timing.

What is the Stroop Test?

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.

Frequently Asked Questions

What is the Stroop Test?

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.

Do I need coding skills to create a Stroop test?

No coding required. AssessKit provides a visual drag-and-drop builder to create custom Stroop tests. You can customize colors, words, timing, and trial sequences without writing any code.

How accurate is the reaction time measurement?

AssessKit captures reaction times with millisecond precision using optimized JavaScript timing. Our platform is built on jsPsych, the gold standard for online behavioral experiments.

Can I use this for research publications?

Yes. AssessKit generates research-grade data suitable for academic publications. Many researchers use our platform for peer-reviewed studies in cognitive psychology and neuroscience.

Is the Stroop test builder free?

Yes, you can create and test Stroop experiments for free. Paid plans are available for larger data collection and advanced features.
