Abstract

A substantial part of the inter-individual variation in everyday cognitive failures in memory, perception and motor control can be attributed to genetic factors. Cognitive failures were assessed with the Cognitive Failures Questionnaire (Broadbent, Cooper, FitzGerald and Parkes,1982) in a large sample of Dutch adolescent twin pairs and their biological parents. The heritability for CFQ scores was around 50 per cent. There was no association between CFQ scores and age or educational level. Both in the parental generation (aged 46 years in average) and in the offspring generation (aged 17.7 years on average) women had somewhat higher mean CFQ scores than men. There were no sex differences inheritabilities. The part of the variance that could not be attributedto genetic factors was best explained by environmental influences unique to the individual. There was no evidence for the influence of shared environment on CFQ scores. CFQ scores of husband and wife were correlated (r = 0.22) and this association was modeled as phenotypic assortment. The correlations between parents and offspring were somewhat lower than the correlations between dizygotic twins. Under a model with equal heritabilities in parents and offspring, there was some evidencethat the genetic factors that influence cognitive failures in the twogenerations are partly different.
