In this study 141 British parents estimated their own, and one of their children's IQ on their overall intelligence as well as on Gardner's (1983) [Gardner, H. (1983). "Frames of the mind: The theory of multiple intelligences." New York: Basic Books.] seven multiple ''intelligences''. Replicating previous studies, fathers gave higher self-estimates on overall, mathematical and spatial intelligence than did mothers. Factor analysis of the seven self-estimates yielded two factors: cognitive and non-cognitive intelligence and there was a significant difference on the former with fathers giving higher self-estimates than mothers. Parental estimates of children's overall intelligence were shown to significantly correlate with children's actual IQ score (r = 0.44), derived from standardized tests of verbal, numerical and perceptual ability. The male advantage for overall intelligence estimates, which was hypothesised, was shown for parental self-estimations but not for estimations of children's intelligence, which showed a female advantage perhaps because girls in this sample actually had higher IQs.
