Developmental Trends in the Processing of Task-Relevant and Task-Irrelevant Information.
Druker, Joseph F.
The role of perceptual discrimination in the development of the ability to selectively process information was investigated. Using an incidental learning paradigm, the discriminability between relevant and irrelevant stimuli was experimentally varied in two ways: (1) contiguity versus non-contiguity in spatial arrangements and (2) alternating versus non-alternating arrangements. The subjects were 80 children in each of the fourth, sixth, and eighth grades. It was concluded that the development change responsible for selective information processing did not involve improved visual discrimination. A post-test questionnaire revealed that older subjects were characterized by more efficient encoding and rehearsal strategies which were postulated as the basis for the older subjects' relatively better ability to selectively process information. This paper comprises a report in "Development of Language Functions, A Research Program-Project (Study C: Development of Selective Attention Abilities)." (Author/DO)
