Given reflection symmetry, the moment generating function symmetry is necessary and sufficient for the random walk model to be equivalent to a sequential probability ratio test. For a related article, see TM 501 715. (Author/RC)

Viewing a threatening stimulus can bias visual attention toward that location. Such effects have typically been investigated only in the visual modality, despite the fact that many threatening stimuli are most dangerous when close to or in contact with the body. Recent multisensory research indicates that a neutral visual stimulus, such as a light…

THEORIES BEHIND PROGRAMED INSTRUCTION, STEPS REQUIRED FOR PROGRAMING, AND THE MAJOR PROGRAMING TECHNIQUES OF EDITING, TESTING, AND ANALYSIS ARE DISCUSSED. TOPICS INCLUDE--HOW TO ANALYZE MATERIAL TO BE PROGRAMED, HOW TO DIAGRAM MATERIAL, AND HOW TO USE VARIOUS CONSTRUCTION TECHNIQUES--DISCRIMINATION, CONSTRUCTED RESPONSE, BRANCHING, BABOON…

A theory of discrimination which assumes that subjects compare psychological values evoked by a stimulus to a subjective referent is proposed. For a related article, see TM 501 716. (Author/RC)

A study was initiated with 60 blind children (kindergarten through grade 2) in order to validate the order of a sequence of tactual discrimination tasks leading to the use of braille and the Optacon. Ss were tested with tasks designed for the readiness level (discrimination of large solid geometric shapes, flat puzzle pieces, embossed dot…

Describes the theoretical backgrounds and empirical findings of three experimental studies in which computer-based response-sensitive strategies were investigated using concept learning tasks. The strategy applied focused on discrimination learning, generalization learning, and classification skill development in concept learning. A general…

TWO STRATEGIES FOR TEACHING MULTIPLE-DISCRIMINATION TASKS WERE REPORTED. THE "MULTIPLE CONCEPT" PRESENTS SIMPLE DESCRIPTIONS OF SEVERAL RELATED CONCEPTS AT THE BEGINNING OF INSTRUCTION. INCREASINGLY COMPLEX MATERIAL PERTAINING TO THESE CONCEPTS IS THEN GRADUALLY INTRODUCED. THE "SINGLE CONCEPT" PRESENTS ONE CONCEPT AT A TIME,…

This collection of 17 papers relating behavioral science theory to the process of experimental education grew out of a 1963 National Education Association symposium on research in programed instruction. Perspectives and the technology of programing are described in this updated and supplemental successor to the source book, "Teaching Machines…
