The learning of backward associations by pigeons during training of forward associations was studied in three experiments using a symbolic matching task. The data are contrasted with the strong evidence of learning of backward associations by humans. (Editor/RK)

The tasks with item and position probes seem similar. Given an item probe, a subject must recall its position in the spatial array; given a position probe, the item in that position in the array. Analysis of correct responses and latencies showed that item and position probes yielded different results. (Editor/RK)

To test the tendency of subjects to perceptually organize discrete temporal patterns with regard to runs of identical stimulus events, spatiotemporal patterns of white noise were presented for reproduction. It is suggested that changes in runs of auditory patterns are perceptually analogous to changes in contours of visual patterns. (Editor/RK)

Experimenters in the past have reported that when insulin is used as the unconditioned stimulus (US), rats will learn an aversion to a sodium chloride but not a sucrose solution, whereas with formalin as the US, they will learn an aversion to a sucrose but not a saline solution. The present experiments failed to confirm these findings. (Editor)

These experiments investigate the degree to which neophobia, the reluctance to consume novel food, can be modified by toxicosis, the conditions under which the contingency between ingestion and illness enhances neophobia, and the manner in which previously learned aversions mediate subsequent enhanced neophobia. (Author/RK)

These experiments investigate situations in which a negative correlation involves a 24 hour delay between the occurrence of a conditioned stimulus and an unconditioned stimulus; they also investigate the mechanism by which any inhibition so produced might occur. (Author/RK)

This research has three purposes: 1) to determine whether subjects instructed to study silently in a free-recall experiment engage in associative encoding, 2) to test the validity of associative ability as an individual difference variable, 3) to test for an interaction between presentation rate and associative reaction time. (Editor/RK)

From experiments showing that subjects differentially attend to parts of the visual field, psychologists have inferred a limitation on human visual information processing capacity. The model presented describes an optimal way to allocate a limited quantity of "cognitive resources", "attention" or "mental effort". An experiment tests this model.…

Presents an overview and an example of use of the Information-Visualization System, an approach to visual selection enabling educators to match desired learning outcomes with the best visuals to carry the message. Decision tables and resource book containing visual options, information types, and suggested methods of enhancing visuals are…

Provides a reproducible flow chart to aid students in problem-solving skill development. Steps include: determining what is asked; choosing a relationship; and checking validity of the relationship. Teacher notes are given to improve instruction. (DH)

Presents a historical perspective of videodisc technology and technical examination of Optical Disc Corporation's (ODC) LaserVision system, an audio/video communication system which stores composite signals on videodisc. Also discussed are premastering, mastering, and replication steps in videodisc production; videodisc player design and…

A workable solution to the problem of how to test out an interactive video program before paying for videotape production and editing involves creating a videotape template of the computer program's flowchart to reproduce the actual interactive experience and thus check for program accuracy. (MBR)

Discusses three task analysis techniques utilized at the Palo Verde Nuclear Generating Station to review training programs: analysis of (1) job positions, (2) procedures, and (3) instructional presentations. All of these include task breakdown, relationship determination, and task restructuring. (MBR)

A method of teaching introductory statistics using student-selected project topics is described. Several activities are noted, with a model for student research projects. (MNS)

Describes the use of a microcomputer system to generate a personal database of books read by adding titles, displaying title/author information, and editing title/author information and discusses the system design, i.e., file structure (author index, book index, book, author), the main driver, function subroutines, and screen subroutines.
