Abstract
There is persuasive but not decisive evidence that females reminisce more than males do because they accumulate more reactive inhibition during prerest trials. The present study provided a further test of this hypothesis within the context of a bilateral-transfer design. 80 subjects, 40 of each sex, practiced continuously with the right hand for five 1-min. trials on a mirror-tracking task. Subgroups of the sample then shifted to continuous left-hand practice after transition intervals of 0, 2.5, 5.0, or 7.5 min. As predicted from theory, the slope of the prerest practice curve was lower for females than for males, and females' inferiority on the first transfer trial declined as the length of the transition interval increased. Sex differences in left-hand performance trends were also consistent with theory.
