Analysis of the stroop effect in rapid serial visual presentation.

Abstract

This study investigated evidence of the Stroop effect in Rapid Serial Visual Presentation (RSVP). Participants were 31 students enrolled in Introductory and Developmental Psychology classes at Emporia State University in the fall of 2000. Participants named the color (ink) that the second capitalized word was displayed in when viewing a series of RSVP streams on a computer. Each stream consisted of 20 items, 18 of those items were lower-case filler items, the other two words (Target 1 and Target 2) were the color names: Blue, Red, Green, and Yellow. Each word in the stream was displayed in one of four colors: Blue, Red, Green, or Yellow. If items appeared between the two target words, those items appeared in White. Significant main effects were found for the variables: Ink, T2, and Lag. A significant interaction effect was found for Ink and Lag. These results indicated that the ink that the target words were presented in (congruent vs. incongruent) made a difference in the proportion of correct responses. Whether T2 was congruent also made a difference in proportion of correct responses. The distance between Tl and T2 also made a difference in proportion of correct responses.
