Hemispheric Asymmetry of the Physiognomic Facial Processing: Its Relation to the Manner of Arm Folding
M. Miura
The present study aimed at investigating individual differences of task-dependent hemispheric superiority in perceptual matching (physical and facial) of face stimuli. Luria's criteria of latent left-handedness was the indices of individual hemisphericity. Forty-five male and female students served as subjects. In both tasks, full face was presented first, which was followed by the second face either to the LVF or to the RVF. The second face was full-face in physical matching and three-quarter face in facial matching. Concerning task-dependent variable, visual field superiority was not observed in physical matching, whereas LVF superiority was shown in facial matching. Concerning individual hemisphericity, a significant "manner of arm folding" x visual field interaction was obtained in facial matching, indicating LVF superiority in "left-arm-uppermost (latent left-handed)" subjects, whereas there was no visual field superiority in "right-arm-uppermost (latent right-handed)" subjects. The result was interpreted as indicating hemispheric advantage of latent left-handers in facial matching.
