Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…

Two concept-learning experiments using adult human Ss were carried out, the first tested prediction using a reversal shift, the second tested speed of shift learning. (Author/RK)

Attempts to clarify the concepts of model, simulation, and game on a theoretical basis, with emphasis on application in the field of computer assisted instruction. (DD)

Differences in the rate of successive acquisition of four concepts as a result of two presentation conditions and their interaction with the learner's preferred strategy was investigated. (Authors)

The process by which a child learns music is discussed. (CK)

Paper based on an MS degree submitted by Raymond R. Baird to the University of Washington.

Described is a technique for determining whether a student can conserve matter. This technique utilizes a square-triangle problem. Included are typical answers and Piagetian-type explanations for such answers. (DS)

Subjects read a text concerning a new computer programing language, with an advance organizer given either before or after reading. On a recall test, there were different patterns of performance. Results suggested that the locus of the effect was at encoding rather than retrieval. (Author/GDC)

The intention of this investigation was to diagnose the retention of some basic skills in some topics in algebra and geometry and to reveal difficult steps in the learning processes in these topics. (MP)

Levels of concept acquisition interms of attribute perception were examined for 20 different chemical concepts featuring in GCE O-level school chemistry courses. (Editor)
