Attentional Performance, Age and Scholastic Achievement in Healthy Children

BACKGROUND: Attentional processes in children play a critical role in daily school demands and accomplishments. Studies on the association of attentional processes with school achievement and age in healthy school children are scarce. The aim of the present study was to identify correlations between dimensions of attentional performance, scholastic achievement and age. METHODOLOGY/PRINCIPAL FINDINGS: An extensive testing battery was used to assess a wide range of attentional dimensions. A principal component analysis revealed three factors that are related to attentional performance (distractibility, lapses of attention, cognitive speed). Age was negatively associated with distractibility, lapses of attention and cognitive speed, indicating that distractibility and lapses of attention decreased with age in healthy children and resulted in lower cognitive speed. CONCLUSIONS/SIGNIFICANCE: Attentional processes in healthy children should be measured in relation to distractibility, lapses of attention and cognitive speed.
