title: Developmental patterns of verbal and visuospatial spans.
abstract: This study presents developmental data for verbal and spatial memory tasks: Corsi's block-tapping test and Luria's verbal learning test. Norms have been collected from 275 primary and early secondary school children aged from 5 years, 4 months to 13 years, 6 months. Our results confirm a slow and constant improvement in performances over time, and the advantage of about 1.5 items of the verbal span over the spatial span supports the existence of developmental differences between separate memory systems. No significant sex difference was found even if a slight trend in verbal span favouring female subjects is present.
