Two experiments involving a total of 177 infants 8 to 11 months of age found that subjects used a global processing strategy like adults' in discriminating transformations of a six-tone melody. Subjects needed melodic contour and frequency range to judge new sequences, but, in easy tasks, they also used absolute frequency. (CB)

As part of a larger experiment to study computer-based methods of teaching Othello, 24 subjects who had never played the game were pretested with visual-spatial tests. After 16 games of Othello, subjects were tested on knowledge of the game. Correlations of pretest and posttest scores were computed. (LMO)

Examines the rhythms of prose, cites several methods of determining language patterns, and concludes that the English language is basically a balanced language. (RB)

Comparisons of the regression profile and correlations of physical measures with latency for a 5-year-old subject (who performed 1250 trials in a form recognition task) with those for a group of 25 adults indicated that use of form information was highly consistent across age levels. (Author/WY)

The Euclidean algorithm for finding the greatest common divisor is presented. (MNS)

The accuracy of deaf adults' letter report was greater for real and nonsense words than for pseudowords, and error analysis shows deaf adults tend to produce orthographically regular responses. These findings indicate clearly the use of orthographic structure in word recognition. (MSE)

Three experiments employed rectangles in stimulus identification tasks. It was concluded that the initial perceptual processing of rectangles is accomplished by separate dimensional analyzers operating in parallel. Observers adopt different decision strategies for negatively correlated sets and for single dimension sets when the number of…

Computer programs to protect a home computer from tampering by a preschool child, while at the same time providing practice for the child in character and shape recognition, are given. (TG)

Presents results of two experiments which measured contrast sensitivity function in infants. Information concerning development of visual acuity, low frequency attenuation, and sensitivity to contrast were collected. Results provide an approximate picture of and means for detection of infants' pattern information. (Author/DB)

Two experiments investigated the process by which children encode briefly presented spatial positions. First, third, and fifth graders were asked to judge whether a test dot occupied the same position on a card as any one of a number of dots which had been presented tachistoscopically. (JMB)

This is the fourth in a series of articles introducing the recently initiated Activities Integrating Math and Science (AIMS) program for the development of a pattern-based mathematics/science curriculum. Discusses proportional relationships, proportional reasoning at the manipulative level, proportional reasoning expressed as written language,…

Thirty-six kindergartners were asked to respond to questions and construct figures designed to test their knowledge of hierarchical relations. Subjects had considerable knowledge of subset and superset classification, and could draw transitive inferences with little difficulty; however, they appeared to have little appreciation of the asymmetry…
