The selective attention of learning-disabled children: three studies.

Abstract

Three studies were performed to assess the selective attention of learning-disabled (LD) children. In the first study, 10 LD and 16 non-LD children were given the Speeded Classification task. LD children sorted cards more slowly than non-LD children, and children in both groups had trouble ignoring irrelevant information. Non-LD children became more accurate across trials, while LD children did not. In the second study, one group of 13 LD children was taught to accompany their Speeded Classification sorting verbally in an attempt to improve their performance; the other group of LD children (n = 12) received no such instruction. The experimental group, however, showed poorer performance across trials compared with the control group. In the third study, the children from Experiments 1 and 2 were given the Central-Incidental Learning Task. Older children learned more central memory items than younger children and, LD children learned more incidentally than non-LD children.
