Abstract: Researchers have generally found greater color-word Stroop interference in the left hemisphere than in the right hemisphere (e.g., Weekes and Zaidel, 1996). Nonverbal Stroop tasks (e.g., Koch and Roid, 2012), however, eliminate words. Two experiments were conducted to test whether or not this difference produces differences in hemispheric processing. In Experiment 1, a typical color-word Stroop task was presented. Results showed slower response times and more interference for the RVF. In Experiment 2, the procedure was repeated except color-color stimuli were presented. Results revealed no differences across hemispheres. Therefore, nonverbal Stroop tasks appear to be processed differently than the original color-word task.
