Age, individuality, and context as factors in sustained visual attention during the preschool years.

Abstract

In 3 studies, the authors explored age changes and individual differences in preschool children's sustained attention in several different contexts--watching a videotape, playing with toys, and performing reaction time tasks. Various indexes of attention increased from 30 months to 54 months, whereas inattention decreased. Changes tended to occur earlier for play and television viewing than for the reaction time task. Together, the results also provide evidence for individual differences in measures of attention and inattention through high internal consistency and stability over time within situations. Correlations across situations, however, were low to modest. These results suggest that children have stable tendencies to focus and sustain attention in particular contexts but that their attention varies with the demands of the task and their ability or interest in meeting those demands.
