The study examined the effectiveness of enhancing perceptual differentiation in the training of four developmentally delayed preschool children who were so low-functioning that they did not demonstrate oddity responding (ability to choose one distinct stimulus from a group of identical stimuli). Instead of the Arabic numerals used in the original…

Investigates third- and fourth-grade children's verbal evaluations of syllables paired with different reward schedules (full, partial, or none) for "pleasantness" and "curiosity." (Author/ED)

Utilizing careful, empirical definitions of lesson kinetic structure, the authors tested two hypotheses: student content achievement is directly related to lesson content structure; and, awareness of commonality and theme development is directly related to lesson content structure. Student achievement seems to be related to communication…

Experiments showed that in verbal discrimination learning imaging the referent of the correct item was more facilitative than vocalizing the correct item, as long as the imagery structure was executed in the company of relevant motor activity. No difference between the two strategies was found in pictorial discrimination learning. (Author/BJG)

Ten randomly picked children of prekindergarten age participated in a study that focused on whether feature analysis can be used as an aid in the recognition of the alphabet. The five children in the control group were introduced to the letters as a whole, while the five children in the experimental group were introduced to the whole letters but…

A schema is best understood as a statistically defined concept. Schematic concept formation consists of abstracting the common elements or properties of a defined class in a schema. Thereafter, both discrimination and retention are facilitated, since only deviations from the schema need be processed for any particular class exemplar. In the…

This study is an exploratory attempt to test the idea that individual differences in the rate of acquisition of an original discrimination learning are related to individual differences in the capacity to estimate the passage of time. Included is a review of the literature on the psychology of time which indicates that underestimation of time is…
