Hand-Eye
Dominance, Cognitive Style, and Reversing: Geometric Illusion Susceptibility
J.L.M. Binnie-Dawson & D.C.M. Wong |
The
recent theoretical and experimental findings are reviewed regarding
a postulated relationship between mixed hand-eye dominance, cognitive
style, and those geometric illusions requiring greater spatial discrimination.
The present data show that mixed dominance right-hand f left-eye
Hong Kong Chinese University undergraduates, were significantly more
field-dependent and susceptible to the Horizontal-Vertical (non-contiguous),
and the Perspective-Drawing Illusions, than fixed dominance right-hand/right-eye
subjects. Thus following Dawson (1973), it is suggested that these
right-eye/left-eye dominance differences stem from two interacting
effects: (a) Higher spatial ability (cognitive style) is required
for illusion-free responses to certain geometric illusions, and;
(b) the effects of eye and acuity dominance interacting with culturally
determined glance curves and position of the illusion in the visual
field. However, there were some problems due to small samples, while
future research in this area will utilize a eye-movement, x-y plotter
design, to improve experimental control.
