Half the subjects were trained to use a serial rehearsal strategy during target set storage and half were given no strategy training. The results indicate that the rate of memory search is IQ-related, and that serial rehearsal training facilitates memory search when rehearsal is covert. (Author/BW)

Assesses the influence of rehearsal on recognition reaction times for items from target lists of a length exceeding the span of immediate memory. Also determines what effect, if any, the length of the target list has on recognition latencies that involve only retrieval from inactive memory. (Author/RK)

A model is proposed in which information processing is accompanied by dynamic processes, including the reorganization of items into active patterns and their subsequent displacement. Research using category names and instances showed that reaction times decreased with each successive repetition under one condition, but longer latencies were…

A study of 25 male college students (both athletes and nonathletes) who where either regular smokeless tobacco users or nonusers as they performed perceptual-motor tasks revealed significant differences in favor of athletes over nonathletes in terms of reaction time. Tobacco-using subjects showed significant increases in heart rate. (Author/CB)

Timed performance measures from a coincidence timing task taking about 10 minutes are shown to have significant correlations with psychometric general intelligence in a group of 56 children. The mean absolute error across three conditions correlated -.294 with Raven's Standard Progressive Matrices scores but was sex-biased, with girls being less…

Twenty fifth- and sixth-grade normal and disabled readers learned the meaning and pronunciation of unfamiliar words varying in length and in letter-sound regularity and complexity. Naming accuracy and latency were more strongly related to both regularity and complexity for disabled readers. (Author/BS)

It was hypothesized that infants' examining behavior, in contrast to other activity, reflects focused attention and active intake of information. The first study with 7- and 12-month-olds supported the hypothesis. The second and third studies investigated the effects of age and familiarity on both latency to and duration of examining.

Effects of information feedback on reaction time (RT) and movement time (MT) on 10 moderately and severely retarded adults performing a discrete aiming task were investigated. Results suggested that specific training and feedback on RT decreased both RT and MT components, whereas specific training on MT reduced only MT. (Author/CL)

Evaluates preschoolers' ability to distinguish left-right mirror-images of objects on a memory task and ability to name rows of objects on a page in a consistent lateral direction. Abilities were assessed first without specific instructions on the relevance of left-right information and then with instructions. (Author/AS)

Compares the semantic processing skills of younger adults (mean age 25) and older adults (mean age 68). After reading a sentence, subjects performed a task in which responses did not depend on retention. Results provided no evidence for age-related changes, including those associated with access to implied information. (Author/RH)

Discusses normative developmental changes in cardiovascular and electrodermal activity and describes the dynamic balance between branches of the autonomic nervous system. Issues for further developmental study are identified, and problems and limitations in the psychophysiological study of children are explored. (Author/RH)

In a free recall task with categorized lists, 40 fifth graders' and 40 adults' retrieval was examined temporally by means of interword response times. List organization and retrieval cue factors were manipulated in order to assess the developmental relevance of an hypothesized three component retrieval model. (JH)

The Ss were required to retain a short list of items for an entire experiment while processing successive different short lists of items in the Sternberg paradigm. (Editor)
