Abstract

Sex differences are reported in the standardisation samples of the WPPSI-IV and the WAIS-IV in Taiwan. There were no sex differences in the Full Scale IQ, the Index IQs or most of the subtests in the WPPSI-IV but males obtained a significantly higher Full Scale IQ of 4.05 points, Index IQs and most of the subtests in the WAIS-IV. These results confirm the developmental theory of sex differences in intelligence that among adults’ males have a higher average IQ than females of between 4-5 points.

Keywords: Taiwan; wechsler tests; sex differences; intelligence; developmental theory
