[Effects of the verbal loading on laterality difference in visual field (author's transl)].
In connection with the Kinsbourne's attention-model, the relation between the level of hemisphere sharing of loading task and the visual-laterality difference was examined under verbal loading conditions. The subjects were 13 (8 male and 5 female) right-handed college students. The loading tasks in Exp. I were the "same-different" judgment of Japanese hiragana alphabets and of triliteral hiragana words, and "true-false" judgment of short statements. In Exp. II, a procedure to eliminate configurational matching of the letters was followed. The results of the two experiments suggest that the visual-laterality effect occurs only when the level of hemisphere sharing of the loading task exceeds a certain lower bound.
