Sex differences in episodic memory: the influence of intelligence

J Clin Exp Neuropsychol. 2002 Feb;24(1):107-14. doi: 10.1076/jcen.


The influence of estimated intelligence (group assessment of WAIS-R( S)) on sex differences in face recognition, as well as verbal and non-verbal episodic memory tasks was examined in 99 women and 88 men between 20 and 40 years of age. Results showed that men performed at a higher level than women on the WAIS-R(S) subtest Information, whereas the opposite was true for Digit symbol. Women performed at a higher level than men on the verbal episodic memory tasks and on face recognition, but there were no sex differences on the non-verbal episodic memory task. Estimated intelligence for both men and women was positively associated with most episodic memory measures, the exception being face recognition in women. In face recognition, there was no association to estimated intelligence, suggesting that face recognition performance in women is unrelated to several basic cognitive processes.
