For example, if someone asked you to say the color of the word "black" that was also printed in black ink, it would be much easier to say the correct color than if it were printed in green ink. A study conducted in 1976 showed that the Stroop test was around 88.9 per cent precise in distinguishing between the participants who suffered from brain damage and those without any brain damage. WebThis demonstration is known as the Stroop Effect, named after its discoverer, J. Ridley Stroop. There are two theories that may explain the Stroop effect: Speed of Processing Theory: the interference occurs because words are read faster than colors are named. Some pathways (reading) are stronger than the other pathways (naming colours), and hence what important is the strength of the pathway in comparison to the speed of the pathway. Investigations of the time course of the Stroop effect have contributed to understanding of the mechanisms of cognitive control.

Vancouver, BC We carry a range of biosensors from the top hardware producers. What is the hypothesis of the Stroop effect? One plausible explanation for the Stroop effect is that humans tend to read words faster than naming colors of the printed words. In other words, if our task is to name the colors and in the meantime ignoring the printed words, then interference is very likely to result.
