The perceived spatiotemporal continuity of objects depends on the way they appear and disappear as they move in the spatial layout. This study investigated whether infants' predictive tracking of a briefly occluded object is sensitive to the manner by which the object disappears and reappears. Five-, 7-, and 9-month-old infants were shown a ball…

If learning is viewed in terms of the tendency to approach a stimulus that has been rewarded and to avoid a stimulus that has not been rewarded, then it must be concluded that the subjects in this study did not learn. (Author)

This study examined the equivalence of objects and pictures of objects in transfer discrimination of 72 children (ages 24-45 months). (BRT)

Results indicate that children's preferences were relatively stable over time. (Authors/MB)

Study found that stimulus presence during a delay of reinforcement interval enhanced performance, and to a large extent prevented the usual delay-produced decrement. (Authors)

This study examined 2- to 3-year-olds' ability to make a pretend-real distinction in the absence of content cues. Children watched two actors side by side. One was really eating, and the other was pretending to eat, but in neither case was information about content available. Following the displays, children were asked to retrieve the real food…

In an attempt to examine the generalizability of the Kendler S-R mediational model of reversal-shift behavior, 60 third-grade children were classified as either verbal mediators or nonmediators on the basis of their performance on an optional-shift discrimination problem. The children's performances were then evaluated on three tasks. (Author/CS)

Explaining new ideas to oneself can promote transfer, but how and when such self-explanation is effective is unclear. This study evaluated whether self-explanation leads to lasting improvements in transfer success and whether it is more effective in combination with direct instruction or invention. Third- through fifth-grade children (ages 8-11;…

Major finding is that recall in the shift condition dramatically exceeded recall in the no shift condition. (Authors/MB)

Intra- and crossmodal performance of normal and retarded third-grade readers were compared in a reaction-time task. Results suggest that the demands of stimulus complexity within the visual modality rather than the demands of crossmodal shifting were related to reading ability. (Author/ED)

Research was designed to explore the basis of children's associations in matching and directed association tasks. (Author)

Study compares the effects of different conditions which imply reversibility on children's judgments of conservation of quantity. (Authors)

A single administration of the reversal learning paradigm is not a sufficient basis for determining either a given subject's choice of option or his behavior on its constituent learning measures. This conclusion raises many questions about past research relating to mediation theory, since this paradigm has been the basic one employed. (Authors)
