Stroop Test

E dey measure how well you fit answer the task wey dey front of you while you ignore strong habit: to read. For 1935, John Ridley Stroop find say e dey take people much longer to call the ink colours of colour words wey no match (for example, the word "red" printed with blue ink) than to call plain colour patches 1. Dem dey call dat slowdown Stroop effect, and na one of the findings wey dem study pass for psychology 2.

Researchers dey use Stroop task to study selective attention and how people control automatic responses 2.

• Dem go show one word at a time (red, green, blue, yellow), printed with one of the same colours. Use the buttons or keyboard answer the ink colour.
• 4 practice words with feedback go come first, then 40 words wey dem go count. For 50% of dem, the word match the ink; for the rest, e no match.
• If you no answer within 3 seconds, dem go count the word as miss. If you leave the page, the run go end because the test get time limit.

• Time wey words wey no match add: your average time for words wey no match minus your average for words wey match, correct answers only. Na dis be your Stroop effect. Smaller number mean the word disturb you less.
• Answered correct: the share of all the words dem count wey you answer correct. If you go faster, you fit lose some accuracy, so look the two numbers together.

Dis version dey show one word at a time, and you answer with buttons, like most computer versions. Stroop own version use printed cards wey people read aloud, so you no fit compare the numbers with im own.

If you get wahala to tell some of these colours apart, like red and green, dis test no fit measure you fairly. Your device colour settings, night mode, or dark-mode filter fit change how the colours look too. Practice with the task fit change your numbers as well, so compare dem with your own earlier runs.

If you want another test wey check how you stop an automatic response, try the go/no-go test.
