Intellectual deficiencies in left-handers: a review of the research.
The purpose of this paper was to examine current research and to determine whether the idea that the majority of left-handers were intellectually inferior to right-handers is empirically supported. This view was inferred in two studies and partially endorsed in another. Inquiry indicated that the cognitive performance of left-handers was not significantly lower than that of right-handers. Based on empirical evidence, then, the idea that left-handers possess cognitive deficits was not demonstrated.
