G.P.’s and R.F.’s performance scores on tests for general intelligence, executive functions, visuo-perceptual abilities and memory functions. For the each tests, reported scores are adjusted for age, education and gender according to published normative data. References from which normative data and normality’s cut-off scores have been reported.
