Participants' usage of informational variables in learning visual relative-mass discrimination in collisions was tracked by means of PROBIT correlations. Four groups received feedback that was true or accorded with either of three nonspecificational cue variables. A majority in each group adopted the feedback, but several participants defied the…

Examines research related to the retina's coding of visual input with emphasis on the organization of two kinds of ganglion cell receptive fields. Reviews current techniques for examining the shapes and arrangement in the retina of entire populations of nerve cells. (ML)

Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

Appraises current explanations of how visual processing occurs. Highlights the basics of simultaneous and serial levels of processing. Discusses the results of a series of experiments on visual-search tasks and also on the role of prior knowledge in processing. (ML)

An effective way to teach the concept of image is to give students a model of human vision which incorporates a simple mechanism of depth perception. In this study two almost identical versions of a curriculum in geometrical optics were created. One used a mechanistic, interpretive eye model, and in the other the eye was modeled as a passive,…

THE DISCRIMINATION OF PICTURES AND PICTURE ELEMENTS AMONG 5TH-, 8TH-, AND 11TH-GRADERS WAS STUDIED (1) TO DETERMINE THE DIFFERENCES IN INTERPRETATION OF SPECIFIC STATIC VISUAL STIMULI WHEN PRESENTED THROUGH TWO TYPES OF ILLUSTRATIONS (PHOTOGRAPHS AND OUTLINE DRAWINGS OF THE SAME SCENES) AND (2) TO GAIN INSIGHT INTO VARIATION IN THE INTERPRETATION…

The accelerating rate of data generation and resulting publications are taxing the ability of scientific investigators to stay current with the emerging literature. This problem, acute in science, is not uncommon in other areas. New approaches to managing this explosion of information are needed. While it is only possible to read one paper or…
