Posttraining rapid eye movement (REM) sleep has been reported to be important for efficient memory consolidation. The present results demonstrate increases in the intensity of REM sleep during the night of sleep following cognitive procedural/implicit task acquisition. These REM increases manifest as increases in total number of rapid eye…

The [delta] subunit of the GABA[subscript [Alpha]] receptor (GABA[subscript [Alpha]]R) is highly expressed in the dentate gyrus of the hippocampus. Genetic deletion of this subunit reduces synaptic and extrasynaptic inhibition and decreases sensitivity to neurosteroids. This paper examines the effect of these changes on hippocampus-dependent trace…

Despite a long history and considerable study, leadership remains a notoriously perplexing and enigmatic phenomenon. Although the "new leadership" perspective has revived convictions and general interest in leadership studies, conceptual and methodological problems nevertheless remain a feature of the research and theory-building terrain, and some…

This paper outlines Explanation Construction Theory, a psychological theory of how people come to comprehend scientific explanations. Explanation Construction Theory has three components: (1) a theory of how scientific knowledge is represented in memory; (2) a taxonomy of different representations that can be formed in response to an encounter…

"Deep" approaches to learning, as defined by Biggs (1987) and others, would generally mean that a student is interested in the academic task, searches for meaning in the task, personalizes the task, integrates aspects of the task into a whole, sees relationships between this whole and previous knowledge, and tries to theorize about the…

The author states that learning theory is useful for economic educators because it enables them to develop instructional theory for economic education. The paper is arranged into five parts. Part 1 focuses on the historical learning theory perspective of economics education. Part 2 defines instructional theory, states its relationship to learning…

Endpoint and distance effects have been observed in the protocols of subjects learning linear orderings. These were produced by subjects learning the frequency of word occurrence as the greater member of a relationship. Error patterns were similar on all trials. (CHK)

Stresses the importance of recitation as a study skill that retards the rapid rate at which individuals forget, citing the experiments of A. I. Gates who revealed that merely reading textual materials is not effective in learning. (RB)

Aspects of chess relevant to certain educational issues are explored. Based on findings from a sample of about 50 children from 6 to 18 years of age, discussion focuses on (1) how children play chess and how the process of acquiring expertise differs among children and adults, (2) chess training techniques and why they are effective with children,…

Cognitive theorists distinguish between two forms of memory. Explicit memory, requiring the conscious reinstatement of episodic memories, is manifested on traditional tests where the student is asked to retrieve information previously learned. Implicit memory is evoked when task completion is facilitated by prior experience with a similar task.…

Two experiments compared the effectiveness of two separate mnemonic devices for learning the states and their capitals--one a complex key word system using substitute words for each syllable, the other a simple key word device interacting key words from the state and capital names in an illustration. In the first experiment, 88 fourth and fifth…

Information-processing students solving problems in the 1960s and 1970s accepted the tradition of early experimental psychology in concentrating primarily on the study of "knowledge-lean" tasks in which competence can usually be acquired over short periods of learning and experience. In recent years, experts have examined knowledge-rich…

This report describes four experiments on various aspects of memory for connected discourse. The first experiment dealt with preexperimental dispositions to respond to sentences and showed that people do come to experiments with biases; therefore, control of materials is necessary in this research area. The second experiment studied the…
