Handedness and sex differences in the processing manner of verbal and spatial information.
Left- and right-handed males and females were given the task of viewing sets of six or eight letters in a 5 X 5 matrix and recalling either (a) the letters, (b) the positions of the letters, or (c) both the letters and the positions. Recall of positions by left-handers was inferior to their recall of letters, and it was inferior to recall of both letters and positions by right-handers. There was no differential recall of letters and positions according to sex. Handedness appears to be a better predictor of cognitive abilities than does sex. The results are discussed in terms of hemispheric specialization referring to handedness and sex.
