Note on a failure to find hemispheric asymmetries for a small sample of strongly left- and right-handed males and females using verbal and visuo-spatial recall.
A column of letters was presented to the left, right, or center of the visual field of 10 male and 10 female subjects. 5 of each sex were either strongly left- or right-handed. The subjects' task was to position correctly the letters on a recall sheet. No significant hemispheric asymmetries emerged, a result that reflects other negative findings. The 10 females were significantly better at verbal identification; this was copngruent with the literature. The 10 males and 10 females were equal in visuo-spatial (positioning) judgments; this did not support the literature. The 5 right-handed males were significantly inferior to the 5 left-handed males and the 10 females at positioning judgments, a result that remained unexplained. The findings were discussed in terms of other contradictory findings.
