About Stroop Test J
The Stroop test is used primarily to assess an individual's impaired response inhibition due to frontal lobe dysfunction, problems with simultaneous interference, and ability to divide attention.
Test instruction:
Respondents are required to touch the words according to the instructions.
At first, measure normal monochrome scores then measure Strooped (color interfered) scores.
Results:
Results are reported as the number of seconds required to complete the task and number of mistakes; therefore, higher scores reveal greater impairment.
A rough standard:
Score is depends on age or gender however most in 50% longer time and less than 10mistakes.
