Kindergarten and first grade children were trained to choose the middle-sized stimulus in either a single stimulus set or in each of two nonoverlapping stimulus sets. Findings were reported in terms of the assumption that cognitive processes are important in the intermediate-sized transposition paradigm. (Author/DB)

To the authors' knowledge, this is the first demonstration that from observation alone, unaided by other means of conveying information, a concept can be retained and generalized to novel stimuli after a substantial elapse of time. (Authors/MB)

This study investigated the spontaneous use of verbal mediators in discrimination learning, the transfer of mediators to a free recall task, and the effects of a pretraining task on performance. The discrimination tasks required nursery school children (80) to: (1) sort three instances each of two different concepts in a conceptually consistent…

The effects of observing a model and of providing a response rule on the learning, transfer, and retention of a dial-reading, numerical concept were studied in 144 third-graders. Different experimenters conducted the immediate learning procedures versus the measurements of retention. No extrinsic reinforcers were promised or dispensed. The…

This study assesses the effects of visual and verbal rehearsal on the problem solving efficiency of preschool children. The study examines the use of stimulus pretraining designed to induce verbal rehearsal and compares the effectiveness of induced verbal rehearsal with the effectiveness of induced visual rehearsal. Fifty-four middle class…
