H30 Stroop Effect
This PRO Lesson explains how to run a classic Stroop test using SuperLab to deliver the stimuli.
If the word “red” is printed in blue ink how will the interference of the ink-color “blue” upon reading the printed word “red” compare with the interference of the printed word “red” upon calling the name of the ink-color “blue?” The increase in time for reacting to words caused by the presence of conflicting color stimuli is taken as the measure of the interference of color stimuli upon reading words. The increase in the time for reacting to colors caused by the presence of conflicting word stimuli is taken as the measure of the interference of word stimuli upon naming colors. (p. 646-647)—Stroop, J.R. (1935). Studies of interference in serial verbal reactions. Journal of Experimental Psychology, 18, 643-662.
- To measure and compare strength of interference between two associative tasks: naming and reading.
- To measure and compare reaction time for the effect of word and visual interference.
- To measure, compare, and correlate the interference of color stimuli upon reading words.
- To measure, compare, and correlate the interference of word stimuli upon naming colors.
