Lateralization, physiognomic perception, and flexibility of cognitive control

32 left-handed and 34 right-handed college educated women were administered a hemispheric lateralization task and measures of physiognomic perception and cognitive flexibility. Results supported the hypothesis that differing hemispheric lateralization patterns would be reflected in differing degrees of physiognomic perception and flexibility of cognitive control. The demonstrated relationships suggest possible structural parallels between hemispheric lateralization patterns and cognitive style. Results further suggest that ambilateralization, rather than reducing hemispheric efficiency, may be a more advantageous psychological organization for certain cognitive tasks.
