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.
