Seven-year-olds completed a Posner cued attention task, under both neutral and affectively charged conditions.

This paper summarizes and integrates the findings from three separate studies, all of which had as their major objective the investigation of differences in small group behavior between children who have relatively high others-concepts and children who have relatively low others-concepts, as measured by the Paired Hands Test. Group sessions of…

Selective attention was assessed in second, fourth, and sixth grade reflective and impulsive children with an incidental learning task using pictures (animal-household object pairs) or shapes (colored forms) as stimuli. By the sixth grade, reflective children displayed less incidental learning and greater central learning than impulsive children…
