Stroop's Theory Of Interference In Cognitive Processing

focuses on mental processes including how people think, perceive, remember and learn. Cognitive processing refers to the operations of the brain while process information. A psychologist that had contributed to this psychological field is John Ridley Stroop. In 1935, he has investigated and developed the theory of the Stroop Effect, which is a study that investigates interference in reaction time. Human reaction is the measurement of time between presentation of a sensory stimulus and the behavioural response to that stimulus. Interference is a variable that interferes with the ability of the individual to appropriately respond to the stimulus presented. This idea of interference has been studied extensively by Stroop when he compared and contrasted reaction time of individuals responding verbally to different stimuli including naming a list of words in black on a paper, naming colored square, naming a list of words in color and naming the incongruent ink color of the words.

Moreover, although asked at the beginning, none of the participants report any issue regarding naming color, however in the experiment, a lot of the participants confused themselves between orange and brown, and purple and pink and therefore the time they spent correcting these errors elongate the reaction time significantly. Resulting in lack of reliability in the final results. In future experiments, this can be eliminated using a simple color blindness testing before beginning and I will choose a different shade of these colors that is easier to distinguish. Thus, the result will only be the measurement of the reaction time instead of participants trying to get the right
