Ja rule mesmerize sample green in blue11/14/2022 Is responsible for executive function in decision making. The impulsivity in ADHD patients is due to the insufficient inhibitionĮxerted by the brain circuitry in the prefrontal cortex of the brain that.Longer time than normal subjects to resolve the conflicts and make more errorsĭue to the insufficient inhibition in the brain circuitry to suppress the Often associated with ADHD (Attention Deficit Hyperactivity Disorder). Thus, Stroop Effect is widely used to indicate mental process of attentionalįatigue and/or the decreased ability to inhibit ongoing competing conflicts.The error in recognizing the correct color when a conflict is present isĪssociated with the "impulsivity" that the brain is unable to suppress.The brain it increases with attentional fatigue and/or inattentiveness. The reaction time is an indicator of the "attentional process" in.This inhibition requires " selective attention" (attentionalįocus) to inhibit the competing conflicting process.In order to allow the color-recognition to win in the final response. The brain has to inhibit the faster/stronger word-recognition process.In order to name the color correctly, the two processes compete for.Most people will recognize the meaning of the word before recognizing.Is slightly faster/stronger than color-recognition. It turns out that we are so fluent in our language that word-recognition.This conflict requires extra processing time for the brain to resolve.The " conflict" between two brain processes are word-recognition and color-recognition.But when the meaning of the word is incongruent with the color,Ĭolor, it creates a conflict between the color and the word's meaning.When the meaning of a word and its color are congruent, such asĬolor, it is easy to recognize the actual color of the word.In 1935, commonly known as "Stroop Effect": John Ridley Stroop first reported this effect in his Ph.D. Here's the correct answer for the incongruent test: Repeat the above a few times to get an average of your response time. Task, so if you retake the test, it will show slightly different reaction The reaction time will increase with fatigue and/or inattention to the If you let the wrong answer to slip through impulsively, without waiting for the right answer to come through, it's because the brain does not have enough inhibition to suppress the wrong choice. The above demonstration does not even take into account the incorrect responses The reason why it takes longer is because the brain has to suppress the wrong answer that interferes with the right answer, before the right answer comes through. This creates a conflict that the brain has to resolve. The second test is hard because the color and meaning of the word are incongruent. The first test is easy because the color and meaning of the word are congruent. Do you notice it takes much longer time to complete the second
