title: Experimentally induced semantic paralexias in normals: a property of the right hemisphere.
abstract: The recently proposed association between semantic paralexias and right hemispheric reading processes was investigated in normals with a tachistoscopic half-field reading experiment. With extremely brief lateralized exposure of nouns, permitting only 25% of correct reading, semantic paralexias were induced. These semantic substitutions occurred three times more often to LVF (right hemisphere) than to RVF (left hemisphere) presentations, whereas other errors were observed with similar frequency to both visual fields. We concluded that semantic paralexias, as they are observed in patients, occur in normals induced by reduced reading time and are the product of right hemispheric reading processes.
