three linear models were used: the raw scores of the three sections were set as dependent variables, and age as the independent (or predictor) variable.Three subscores were the residuals of the relative linear models, standardized and transposed to a scale with M=100 and SD=15. This allowed all participants to be systematically compared with their corresponding age class.
