Chapter 12 The Development of Attentional Control Mechanisms

摘要: Research on the development of selective attention in children has focused increased selectivity that manifest as they grow older. Three studies were conducted to elucidate contribution two primary sources age differences attentional selectivity: (a) Stimulus factors involve perceptual skills, particularly skills required for stimulus differentiation. (b) Attentional efficiency involves with which specific control mechanisms are applied. This may improve have opportunity use these skills. The first minimized role using materials and tasks reduced demands differentiation processing factors—emphasis was placed visual shifts deployment. In a third study, interaction studied. Results demonstrated considerable source developmental variance is attributable continuing efficient mechanisms.
