Effect of auditory presentation of words on color naming: the intermodal Stroop effect.
To verify two hypotheses (the automatic parallel-processing model vs the feature integration theory) using the Stroop effect, an intermodal presentation method was introduced. The intermodal presentation (auditory presentation of the distractor word and visual presentation of color patch) separates completely the color and word information. Subjects were required to name the color patch on the CRT and to ignore the auditory color-word in the present experiment. A 5 (stimulus onset asynchronies) x 4 (levels of congruency) analysis of variance with repeated measures was performed on the response times. Two main effects and an interactive effect were significant. The findings indicate that without the presentation of color and word component in the same spatial location the Stroop effect occurs. These results suggest that the feature-integration theory cannot explain the mechanisms underlying the Stroop effect.
