Experimental Psychology: The Stroop Effect

Decent Essays
The Stroop Effect is a popular phenomenon used throughout experimental psychology. It detects interference and inhibition by having participants’ naming at the color ink presented on paper or index cards and not being conflicted by other stimulations such as the written word. It is measured by the delay in response time. J. Ridley Stroop (1935) designed the original Stroop test using multiple experiments. He discovered in his second experiment that it took participants longer to name the color ink if the written word was not written in the color. For example, it took participants longer to respond “red” if the ink color was in red, but the word printed was “blue” (Stroop, 1935). Additionally, participants could quickly name the color ink if the word matched its color. Many researchers have conducted replications and redesigns studies looking at other aspects to better explain the phenomenon.
A recent study, researchers looked at different aspects of Stroop’s (1935) results to receive a better understanding of interference. Bindl, Bühner and Hilbert (2014) tested for the original Stroop effect using a position-word interference test to examine spatial recognition and color words. One of the two spatial position-word task was done manually in order to control

First, they tested their participants on a reading-span test to distinguish groups based on their memory capacity. Once the participants were grouped into high-span or low-span categories, experimenters conducted the original Stroop test (1935). They discovered there was no significant difference between the high and low working memory capacity individuals. However, high-span individuals did display less interference in the more complex trials than low span-individuals (Long D. et al,
