AnnotationTwo studies were designed to determine which of several hypothesised components were primarily responsible for the age-related effects on matrix reasoning (Study 1) and analytical reasoning (Study 2). In neither case were the analyses successful, because the variables selected to assess the hypothesised components failed to exhibit discriminant validity, and also had few unique age-related influences. These results, along with the results of other analyses, suggest that large proportions of the age-related effects on different cognitive variables are shared, and are not independent of one another.
