Verbal and spatial encoding of visual stimuli: the effects of sex, hemisphere and yes-no judgements.
Six male and six female subjects were given 112 trials on each of two tasks requiring a yes-no comparison of pairs of letters presented to the right and left hemispheres. One task was predominantly visual (detection of curved letter segments) and the other was predominantly verbal (detection of rhyming "ee" sounds). It was found that for "yes" decisions, females were faster in the right hemisphere than in the left, while the reverse was the case for males. Also for females "no" decisions were faster than "yes" decisions in the left hemisphere but "yes" decisions were faster than "no" decisions in the right hemiphere.
