Investigated the effect of correction and noncorrection procedures on the occurrence of the overlearning reversal effect (ORE) in 80 children 4-6 years of age. Results showing the existence of ORE at the preschool level are explained in terms of a response-switching strategy. (GO)

Nursery school and second grade subjects were trained on an optional shift task and results were compared with predictions derived from selective attention theory. Findings indicate that the one-look assumption does not hold and that a multiple-look theory, in which the breadth of attention varies with task demands, seems tenable. (GO)

Two experiments show that response to explicit dimensions is not crucial to the change from easier nonreversal to easier reversal shifts during overlearning in grammar school children ages 7, 8, and 9. (WY)

Reversal and nonreversal shifts in 19 2- to 14-year-old autistic children were studied. Results indicated that the older autistic children did better on reversal shifts than did younger children, who performed better on nonreversal shifts. Findings were consistent with those for normal children. (Author)

Uses the balance scale task to assess the development of compensation across versions of the task. Shows that fully reversible thinking may not be typical even in college students; many subjects used the compensation operation inconsistently. Preschoolers tended to use the given information in a way that was opposite to that required for correct…

It is urged that investigators lay aside demonstrations of the existence of mediation in young children as focus of research, substituting a search for the conditions of its occurrence. (Authors)

Presents a theoretical account of human shift learning with the use of neural network tools. Details how simulations using the cascade-correlation algorithm which show that networks can capture the regularities of the discrimination shift literature better than existing psychological theories. Suggests that human developmental differences in shift…

Investigates the development of evaluative and taxonomic encoding in 7-, to 8-, and 11-year-old children's memories, and related experimental findings to recent work on the development of encoding in memory. (Author/ED)

Three experiments are reported that were designed to test the effectiveness of two training procedures, one perceptual, the other verbal, on upgrading the conceptual behavior of preschool children. (Authors/MB)

Two groups of mentally retarded children (MA: 4 to 8 years) were pretrained using two different methods. It was predicted that shift performance of the two groups trained to use different strategies would resemble those of two different developmental levels. (MP)

Facility in shifting between familiar schemata in a listening comprehension task was examined in children from the third and sixth grades. Analyses of free recall and interview responses showed deficiencies in children's cognitive monitoring of the prose-schema interaction. (Author/CI)

Experiment was designed to teach the oddity principle to preschool age children whose age peers in earlier studies have had difficulty learning the oddity principle. (Authors)
