Abstract: | Subjects reported letter strings forming words, pronounceable high approximations to words, and unpronounceable low approximations to words presented tachistoscopically to the left or right visual field (LVF, RVF). (a) For number of strings totally correct, the same RVF superiority was obtained with high approximations as with words, the field difference with low approximations being negligible. (b) In contrast, for letter scores from partially correct strings, RVF superiority did not vary with string type. Finding (a) is interpreted to indicate that the left hemisphere is differentially specialized for processing words as units and that requiring oral report makes pronounceable strings processable as word-like units. Finding (b) suggests that the left hemisphere is not specialized for processing subword fragments. |
