This study was designed to determine if: a) attentuation of irrelevant information on a selective attention task would result in increased selective attention, and b) a developmental increase in selective attention would be replicated with the use of a different procedure of data analysis than has been used previously.

The development of capacity for attention was assessed by giving children 5, 8, 9, and 12 years of age a component-selection task with instructions to attend to one component or another, or with no specific instructions regarding the stimuli. (CM)

Recent theoretical analyses have implied that there may be age differences in children's tendency to exercise component selection, i.e., to attend selectively to a single component of stimulus objects in a learning situation. In the present study, 6 experiments were conducted, each designed to investigate developmental changes in component…

Three strategies of attention were investigated in two dichotic monitoring experiments. Subjects were divided into three groups, 7, 11 and 20 years of age. (CM)

This appendix includes seven papers which focus on various aspects of the learning processes of children ages 5-7: (1) S. Thompson, "Transitions to concrete operations: A survey of Piaget's writings" (in outline form); (2) S. H.
