Neuronal modifications that accompany normal aging occur in brain neuropils and might share commonalties across phyla including the most successful group, the Insecta. This study addresses the kinds of neuronal modifications associated with loss of memory that occur in the hemimetabolous insect "Periplaneta americana." Among insects that display…

The papers included here are based on a 1971 symposium held at the annual meeting of the Western Psychological Association in San Francisco. The first three papers report the results of research carried out over the last few years at the Wisconsin Research and Development Center for Cognitive Learning. Levin's paper focuses on the effectiveness of…

Addresses two questions that may be unique to perceptual learning: What are the circumstances that produce learning? and What is the content of learning? Suggests a critical principle for each question. Provides a discussion of perceptual learning theory, how learning occurs, and what gets learned. Includes a 121-item bibliography. (DR)

Four studies examined 10- to 18-month-old infants' ability to detect and encode correlations among features in a motion event. Findings indicated that the youngest infants process static features in an event independently but do not process correlations among dynamic features; the oldest detect correlations between all three features when the…

Two experiments examined the origins of joint visual attention in 6- to 11-month-olds with a training procedure. Results indicated that joint visual attention does not reliably appear prior to 10 months; from about 8 months, a gaze-following response can be learned; and simple learning is not sufficient as the mechanism through which joint…

A description is given of an experiment investigating the applicability of a cybernetic theory in teaching children psychomotor skills. Results showed a learning effect in copying for younger subjects, in tracing for older subjects, and in tracking for all subjects. (GK)

Children at three age levels (four-, six-, and eight-year-olds) were asked a series of class inclusion questions presented verbally, visually, and kinesthetically. Analysis of correctness of reasons showed main effects of age and of condition. (Author/GK)

Preplays (critical material presented before a televised program) were inserted before three sections of a televised story to determine if they would improve children's attention and comprehension by providing overall plot structure for selecting and integrating important story events. The preplays varied on two orthogonal dimensions: presence or…

A Study of students' preferred learning styles at Sinclair Community College utilized the Learning Styles Inventory (LSI), which provides 100 discriminations within the following categories: Conditions, reflecting concern for learning situation dynamics; Content, indicating major areas of interest; Mode, showing the general modality through which…
