Abstract: | Sex-related differences in global/local hemispheric selective processing were examined by hierarchically presented letters
in conditions of their perception and comparison. Fifty-six right-handed men and 68 women (aged 17–22 years) participated
in the experiment. During the interference between global and local aspects of stimuli, the mean reaction time for correct
global responses was shorter than for local responses, and the right hemisphere dominated during global selective processing
independently of sex. Sex-related differences in perception of visual hierarchical stimuli were more pronounced than during
their comparison: men preferred the right-hemispheric global strategy of information processing, and women, the left-hemispheric
local one. The dominance of the global strategy in men and local strategy in women during visual hierarchical stimuli perception,
together with the absence of sex-related differences in correct responses indicates the possibility of obtaining the same
efficiency of cognitive activity in different ways. |
