Sex Differences in Speed of Mental Rotation and the X-Linked Genetic Hypothesis.

Thomas, Hoben; Kail, Robert

Intelligence, v15 n1 p17-32 Jan-Mar 1991

Mental-rotation task response times from 12 studies involving 505 adults--251 males and 254 females--were used to evaluate 5 hypotheses concerning sex differences derived from an X-linked genetic model. The model assumes that task facilitation in speed of mental rotation is mediated by a recessive gene. Four hypotheses derived from the model were confirmed. (Author/SLD)
