Correlations between elementary sensory tasks and IQ scores support Galtonian theories of intelligence, which emphasize speed of signal encoding and transmission in the nervous system.

Examines the readability and educational levels of 25 periodicals, classified as newspaper format, neutral, minority, male, and female magazines. Indicates that periodicals have similar readability levels but significantly different reader education levels.

This article considers a set of assumptions about the antecedents and consequences of effort expenditure when a subject is engaged in achievement-oriented behavior. It examines both static models (level of effort is constant over trials) and dynamic models (preceding task outcome may influence current level of effort). (Author/BW)

The article describes studies of effectiveness of a secondary task as a measure of the blind mobility information processing workload. Secondary task performance is shown to be a useful index of effects of preview and route difficulty, as well as perceptual and cognitive demands of different mobility aids. (Author/CL)

A method of analyzing textual learning materials is described. Using data from student questionnaires, the method reveals the underlying structure of concepts in the materials and can pinpoint the location and cause of student difficulties.

This extensive annotated bibliography lists sources related to Supplemental Instruction (SI) and Video-Based Supplemental Instruction (VSI). The SI model of academic assistance helps students in historically difficult classes master content while they develop and integrate learning and study strategies. SI was created at the University of…

Errors made by 5- and 8-year-old children asked to draw a model were investigated in two studies. Results from both indicated that 5-year-old children are more likely to produce visually accurate drawings than had previously been supposed; for both ages difficulty in producing accurate drawings occurred when drawing rules and conventions…

Children ages 6 to 13 and college students were asked to remember length relationships for three pairs of sticks. For six- and seven-year-olds, relationships between interlinked pairs were much more difficult to retain than were relationships between unrelated pairs. (Author/MP)

Both between- and within-group differences in children ages nine to eleven identified as having reflective or impulsive cognitive tempos. Cognitive tempo was first assessed using Kagan's Matching Familiar Figures test, and children were later tested on the Raven's Standard Progressive Matrices. (Author/RH)
