Mathematical ability and the right-shift theory of handedness.

Neuropsychologia - 1 Jan 1991

Whittington J E, Richards P N

Abstract excerpt

A genetic theory of handedness, the right-shift theory, associates differential patterns of cerebral functioning with contrasting handedness groups and suggests that individuals with an rs + + genotype will be disadvantaged in mathematical performance. This hypothesis is investigated with contrasting handedness groups drawn from a national sample of over 11,000 children from the National Child Development Study....
