Differential recognition of tachistoscopically presented English and Hebrew words in right and left visual fields.

Abstract

In this study, the role of lateral cerebral dominance in the consistent finding of lower tachistoscopic thresholds in the right than in the left visual field for alphabetic material was tested for readers of Hebrew and English. Twenty Israeli Ss were presented with Hebrew and English three-letter words, printed vertically, through a monocular tachistoscope, displaced to left or right of fixation by 2°21′. Ten American Ss were also tested for three-letter English words, under similar conditions. Significantly lower thresholds in the right field were found for both groups and for both languages, despite the fact that Hebrew, unlike English, is read from right to left. These findings tend to support the hypothesis that alphabetic stimuli arriving in the major cerebral hemisphere are more readily recognized than similar stimuli arriving in the hemisphere contralateral to the language areas.
