Abstract:
Three experiments investigated interhemispheric interactions in number comparison using the interhemispheric Stroop-like paradigm (E. Ratinckx, M. Brysbaert, & B. Reynvoet, 2001). In all experiments, a target was presented in I visual field simultaneously with a distractor in the other visual field. In Experiment 1, both target and distractor were of the same modality (Arabic digits), whereas in Experiment 2, target and distractor were of different modalities (Arabic digits and word numerals). In Experiment 3, the interhemispheric Stroop-like task of Experiment 1 was combined with intrahemispheric conditions to evaluate the strength of the interhemispheric interactions. Overall, the results point to strong interhemispheric integration during semantic access and response preparation with very weak lateralization of the semantic number system.
