Although there has been previous research concerned with image size, brightness, and contrast in projection standards, the work has lacked careful conceptualization. In this study, size was measured in terms of the visual angle subtended by the material, brightness was stated in foot-lamberts, and contrast was defined as the ratio of the…

Concerned with the need to offer high school students organized practice in observing visual stimuli and writing about what they see, the author offers an annotated list of short films with little dialogue and narration that can conveniently be used in the classroom for teaching observation through the moving image.

This paper deals with research on the development of infants' ability to perceive invariant features of things and the relation of objects to both the spatial layout of the infants' environment and to themselves. Basic assumptions regarding the perception of invariance are discussed and a theoretical view of the role of motion in the development…

Little research has been conducted into the structure of television images. This structure merits examination in terms of its perceptual psychology, composition (light, color, form, placement, sound, and editing), and the aesthetics of motio Field forces theory asserts that there are differences between a real scenario and its representation on…

The essays in this book concern themselves with the carefully sequenced interplay between sensory, imaginative awareness and disciplined, scientific knowledge. They deal specifically with sharpening visual perception. The opening essays analyze the fundamental characteristics of visual faculties. The next group of essays deal with vision as an…

Proceedings of a seminar on the present status of vision engineering and the possible effects on criteria for school planning. A discussion by Dr. H. Richard Blackwell on vision engineering is included. Topics of discussion include--(1) broad aspects of the effect of light upon sight, (2) lighting variables and task visibility, (3) lighting…

The results of all basic measurements and calculations of reflected glare for different lighting materials and conditions are presented in a series of tables and charts. All basic concepts of a quantitative method for evaluating the visual significance of reflected glare are identified in relationship to different types of visual performance. The…

THE ROLE OF VISUAL SENSORY DEFICIENCIES IN THE CAUSATION READING DISABILITY IS DISCUSSED. PREVIOUS AND CURRENT RESEARCH STUDIES DEALING WITH SPECIFIC VISUAL PROBLEMS WHICH HAVE BEEN FOUND TO BE NEGATIVELY RELATED TO SUCCESSFUL READING ACHIEVEMENT ARE LISTED--(1) FARSIGHTEDNESS, (2) ASTIGMATISM, (3) BINOCULAR INCOORDINATIONS, AND (4) FUSIONAL…

The main objective of the present investigations was to determine whether or not young human infants see the physical spectrum in a categorical fashion as human adults and animals who possess color vision regularly do. (Author)

The span of apprehension (a measure of the amount of information processed simultaneously from a brief visual display) was studied in two experiments involving 40 normal and learning disabled boys (ages 6-11 years). (Author/DLS)

Reports a series of experiments that give evidence for retention of information about color in very short-term visual memory, commonly termed "iconic memory". (Author)

In a study involving the reading of bar graphs it was found that students in the control group (who did not receive generalization cues) did significantly better than those in the experimental group. (Ed.)

Sense of direction was studied as a verbal expression of people's estimation of their own spatial orientation ability, rather than as a special mental faculty. Relates sense of direction to cognitive ability and to self concept. (Editor/RK)

Investigations of the relation between judged length and measured length have concentrated on determining the form of the psychophysical function. The process by which the observer arrives at his judgment has not been described. An exploratory experiment was carried out in an attempt to identify the process. (Author)
