About this app

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 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.
