Plyometric exercises or drills combine speed and strength to produce an explosive-reactive movement or increased power. Some world-class athletes have used plyometric-training in sports such as high-jumping, hurdles, football, baseball, and hockey. The method is still considered experimental. Sample exercises are described. (JL)

The author replies to Jensen and Vernon's article and maintains that there is little reason for accepting Jensen's claims, particularly with respect to the major theoretical question. (Author/LMO)

The present article is concerned with the ways in which Ss are able to make use of organizational cues in order to facilitate retrieval of information from memory. (Author)

The separate effects of stimulus and response relative frequency were studied in two choice reaction time tasks containing many: 1 stimulus-response (S-R) mappings and 2 levels of S-R compatability. (Editor)

The present experiment was designed to investigate recognition memory processes in a task in which the items to be recognized were stored in long-term memory (LTM), in short-term memory (STM), or in both memory stores. (Author/RK)

Authors note that Fehrer and Biederman's two statistical tests were not of equal power and that their conclusion could be a statistical artifact of both the lesser power of the verbal report comparison and the insensitivity of their particular verbal report indicator. (Editor)

Paper reports some definite differences in response latencies that clearly seem to reflect the existence of racial awareness in the white, second-grade children who served as Ss. (Author)

The major hypothesis of the study was not supported by the data. Brief exposure to perceptual deprivation did not facilitate reaction times in either the younger or older group. (Author)

Two techniques of anxiety reduction are studied singly and in combination: rapid repetition of words and paired-associate learning. Paired-associate learning with Counteracting Response Associates yielded the best long-term reduction in response anxiety, which suggests the potential application of this technique in therapy.

Study to determine whether learning is a phenomenon of input processing, output processing, or both. (Author/DS)

Investigated were the relationships among confidence judgments, latencies, and memory-trace strength." (Authors/MB)

Data indicate that the developmental level of an individual is a significant factor in trace conditioning performance. (Authors)

Cognitive style was modified in a sample of 50 impulsive and 50 reflective fourth-grade boys. Subjects viewed a film-mediated model displaying a response style opposite to their own cognitive style. The specific cues in the model's behavior which facilitated shifts in cognitive style varied with the intellectual levels of the subject. (Author/WY)

Results support the contention that infant attention should be divided into separate attention-getting and attention-holding processes. (Author)
