This study used a rating scale, a betting game, and a feedback phase to examine the certainty with which 60 second graders and 36 fifth graders made judgments on tasks involving various forms of conservation and transitivity. (Author/JMB)

The effects of delay of information feedback interval (0 or 7 seconds), postinformation feedback interval (1, 8, or 15 seconds), difficulty (one or three variable irrelevant dimensions), and presence or absence of a tractor in the postinformation feedback interval were investigated with 240 junior high school children in a modified…

The effects of modeling and corrective feedback on the conservation of equalities and inequalities were studied. Both training methods were successful in teaching children to conserve. Trained children were also capable of generalizing their learning to new conservation tasks. (CS)

This study used delayed nonmatching to sample (DNMS) to test the recognition memory function dependent on the medial temporal lobe. Results from three conditions of DNMS tests with 9- and 12-month-olds suggest that the critical late-maturing competence accounting for DNMS success is the ability to understand that the stimulus is a symbol or marker…

Discusses the respective roles of rate of learning and level of cognitive development in determining intellectual performance in 156 normal and retarded children matched for mental age. (Author/LLK)

First-, third-, fifth-, and sixth-grade children were administered 20 relational reasoning problems in which they had to deduce the possible sizes of one item relative to two others on the basis of a visual comparison and a written clue. Dramatic differences were observed between fifth- and sixth-grade children. Corrective feedback improved…
