Abstract

In this study, the question of hemispheric abilities in processing explicit semantic and phonological information was addressed by measuring responselatencies and performances in two judgement tasks. In the semantic task, word pairs were sequentially presented to the left or right visual field andsubjects were asked to judge whether these words were categorically related or not. In the phonological task, the same subjects were asked to decide whether pairs of orthographically dissimilar words rhymed or not. Statistical analysis showed that reaction times (RT) were significantly shorter in both tasks when words were presented to the right visual field. Furthermore,in the semantic task, faster responses were observed in both visual fieldswhen the words were related than when they were unrelated. This response facilitation tended to be stronger when words were presented to the left Visual field. This result is in accordance with other results obtained by lexical decision studies showing that priming in the right hemisphere is due tocontrolled processing. By contrast, RT differences between rhyming and non-rhyming word pairs in the phonological task did not reach significance. This supports previous findings showing that phonological facilitation cannotoccur when orthographic and phonological indices are in conflict.
