Notes: Data are presented as mean (SD). AP, accuracy of performance (arcsine transformation of the square root of the proportion of correct responses); ER tot, total number of errors; DR, delayed recall (number of correct responses); CR tot, total number of correct responses.; Acc, accuracy (arcsine transformation of the square root of the proportion of correct responses). Significant p-values are shown in italics.
