[The asymmetry of interhemispheric interaction in reverse-stroop task].
The purpose of the present study was to examine the effect of interference on interhemispheric interaction in the reverse-stroop task. In two experiments, color-word in black ink and color-patch in red or blue ink were briefly presented to a bilateral visual-field (BVF). The participants were asked to identify the color word, ignoring the color patch. In Experiment 1, color-words written in kanji character were used as target ([Chinese character: see test] or [Chinese character: see test]). In Experiment 2, color-words written in kana character were used as target ([Chinese characters: see test] or [Chinese characters: see test]). The result in Experiment I showed that the size of the interference effect was invariant irrespective of the visual-field of the target. On the contrary, in Experiment 2, the interference effect was larger in the condition where the kana color-word was presented to left visual-field (LVF) than to right visual-field (RVF). These results suggested that the interference effect would be modulated by the dominant hemisphere for processing the target.
