To what extent does prior knowledge of a superordinate category facilitate recognition of an instance of that category? The results of this study reveal that the facilitating effect of a category prime on perceptual processing is inversely related to the quality of the stimulus information available. (Author/RK)

Spanish-English bilinguals were tested for the speed with which they could recognize a word in one language as a member of a previously presented set of words in either language. Reaction time increased with the size of the presented set of words. Investigates the "translation effect" and its influence on information processing. (Editor/RK)

The body reaction times of 43 mentally retarded boys (ages 7-13 years) were measured and compared to those of a similar but larger group of normal boys. (Author/DLS)

The results of two experiments indicate that the two phonological properties of a word, its initial phoneme and length, strongly influence the latency to detect a target phoneme which begins the following word. Studies showing increased detection latencies following ambiguity are analyzed. (SW)

Response latency (RL), accuracy, and confidence data were obtained from six subjects, each tested for 20 experimental sessions in a long-term recognition memory paradigm. Based on signal detection theory assumptions, functions were derived that described the relationship between RL and the separation of test item and criterion along a theoretical…

Investigated with 10 educable retarded and 10 non-retarded junior high school and high school students were overt indices of attending behavior during a simple reaction-time task. (Author/DB)

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)
