Three experiments were conducted to examine the effects of stimulus exposure duration, retinal eccentricity, visual noise and task differences (physical classification and semantic classification) on the processing of Kana (Japanese phonetic symbol) words presented to the left and right visual fields. The primary findings of the three experiments were as follows. The right visual field advantage was found in the shorter exposure duration but no visual field difference was shown in the longer exposure duration condition (experiment 1). Stimulus presentation to large and small retinal eccentricity conditions revealed similar visual field difference (experiment 2). No significant visual field difference was shown in both clear and blurred stimulus presentation conditions (experiment 3). Semantic classification task revealed a right visual field advantage in all experiments whereas no visual field difference was shown in physical classification task in experiments 2 and 3. These results were discussed in terms of spatial frequency hypothesis and levels of processing hypothesis.
