Relationships between the manner of hand clasping and the individual differences in hemispheric specialization measured by the degree of either perceptual asymmetry (using composite symmetric faces) or individual hemisphericity (using the hemisphericity task by Ogura & Hatta) were examined. Subjects were 46 right-handed college students (23 males and 23 females). In the face perception task, the L-type subjects who clasp the hands with the left thumb uppermost showed greater degrees of asymmetry than the R-type ones. In the hemisphericity task that examines preferences for either the verbal (letters or numerals) or the non-verbal (pictures) materials, the L-type subjects preferred the non-verbal materials more often than the R-type ones. These results were discussed in relation with the asymmetric hemispheric arousal model proposed by Levy, Heller, Banich, & Burton (1983).
