Behavioral studies of early visual development are interpreted within a framework provided by data from the neurosciences. Conclusions concerning the visual responses elicited during the first month of life and the more sophisticated reactions appearing during the second and third months of infancy are presented. (Author/SDH)

A test of relative effectiveness of visual and verbal modes of giving instructions. (CH)

First-grade children of average or above intelligence who did not evidence visual perceptual dysfunction were administered a series of visual perceptual tasks. Results indicated considerable method of measurement influence upon task performance. Implications of the results for both researchers and practitioners are discussed. (Author)

Four experiments investigated the phenomenon of letter migration, the tendency of readers to assign letters from one word to another appearing in close proximity. The experiments, which involved college undergraduate students, revealed several properties of letter migration, including the following: (1) migrations are more frequent when the words…

As the viewer watches the opening credits for the program "Entertainment Tonight," the screen comes to life with rotating shapes and spinning geometric patterns. One has the sense of travelling on an imaginary voyage through space. Many of the computer generated displays common now on television use such visual devices as linear perspective,…

The booklet provides an overview on vision therapy to aid writers, editors, and broadcasters help parents, teachers, older adults, and all consumers learn more about vision therapy. Following a description of vision therapy or vision training, information is provided on how and why vision therapy works. Additional sections address providers of…

Author argued that in our efforts to understand the environment we should not neglect the technology which makes building possible. He noted that construction methods can give us information about culture and history. He proposed an intriguing way of teaching structural principles via symbols. (Editor/RK)

We investigated the properties of the distribution of human solution times for Traveling Salesperson Problems (TSPs) with increasing numbers of nodes. New experimental data are presented that measure solution times for carefully chosen representative problems with 10, 20, . . . 120 nodes. We compared the solution times predicted by the convex hull…

We tested human performance on the Euclidean Traveling Salesman Problem using problems with 6-50 cities. Results confirmed our earlier findings that: (a) the time of solving a problem is proportional to the number of cities, and (b) the solution error grows very slowly with the number of cities. We formulated a new version of a pyramid model. The…

In the present study, and attempt was made to clarify whether right visual field superiority, in terms of shorter latencies to verbal material, transcends the directional scanning tendencies associated with the stimuli. (Author)

Suggests that the teacher who wants to lead children toward visual literacy and eventually to reading and writing skill must help children explore what they themselves perceive and how and why they perceive it. (TO)

A computer-displayed 3-D tic-tac-toe game was used to investigate adult perceptual biases in dealing with diagonal line orientations. Also investigated was the interaction between prior spatial ability and the effects of explicit visual modeling and structured practice on performance. Results indicated a strong selective difficulty in dealing with…

The thirteen chapters in this collection provide a detailed examination of visual perception and visual constancy. After a first chapter providing an historical overview of the field, the 11 central chapters present reports on current research from leading investigators. A final chapter brings into focus a variety of methodological, empirical, and…
