Children from 4 to 7 years of age were tested in a structured perceptual task in which haptic manipulation was available, but not required. The extent of haptic involvement with the stimulus material and its effect on performance in a perceptual recognition task was then determined. (Author/CB)

The similarity match took longer than the identity match, and the difference in latency increased as the number of lines in the pattern increased. (Author)

Results demonstrate that 12 - 15 - week-old male infants smile to nonsocial stimuli, and offers support for the recognition hypothesis of infant smiling. (Authors/MB)

Outline faces were presented for rating along six dichotomous attributes with features varying systematically. Differences were found to be largely attentional, with certain features invariably being differentially employed and associated with certain attributes across all samples. (WY)

No significant relationship was demonstrated by 41 preschool children who were asked to identify some represented body parts which were displayed in a scattered array on a page and the ability to draw or assemble a person. (PN)

A model of context effects in perception is applied to perception of letters. Perception results from excitatory and inhibitory interactions of detectors for visual features, letters, and words. The model produces facilitation for letters in pronounceable pseudowords as well as words and accounts for rule-governed performance without any rules.…

Reviews recent progress in modeling human cognition, in particular the use of computers in generating models. Topics covered include the information processing approach to cognition, problem solving, semantic memory, pattern induction, and learning and cognitive development. A 164-item reference list is attached. (JL)

The assumptions underlying the classfication rule-learning description of concept acquisition are critically examined. An alternative characterization of what it means to have a primacy hypothesis and Gibson's position that knowledge of the world is a product of direct perception are discusssed. (Author/RD)

Describes a study of 16 kindergarten children--eight good prereaders and eight poor prereaders--designed to determine if there were relations between reading skill and the processing of distinctive features of patterns. Concludes that both pattern classification and feature processing appear to be involved in early reading skills. (TJ)

Having students find and cut out of graph paper the 12 pentominoes can provide an enjoyable exercise in perception, discovery, and double checking. The pentominoes can then be used to illustrate informally several geometric concepts. (SD)

Four commissurotomy patients were tested for ability to match tachistoscopically presented stimuli with pictures in free vision, according to either structural appearance or functional/conceptual category. (Editor)

Presents several examples of investigations which demonstrate the following: (1) algebra is connected to other mathematical topics; (2) algebra is an effective tool for representing patterns and relationships; and (3) algebra is an effective tool for analyzing patterns. (DDR)
