Stroop Effect Challenge

Stroop Effect Challenge is an app to test your attention skills, cognitive flexibility and processing speed.


You'll be presented with a sequence of 30 words. Identify the color used to display each word as quickly as possible. For example, if the word "Bumfuzzled" is displayed using the color red, then press the button labeled "Red". However, there's a catch. The words are the names of colors!


This app is based on an observation by John Ridley Stroop that incongruent stimuli makes doing certain tasks more difficult. To learn more, search the Internet for "Stroop Effect".
