Subjects looked at two optically superimposed video screens. They were required to selectively look at two episodes and monitor significant action taking place. Results showed difficulty in monitoring two episodes at once and that selective viewing does not involve special mechanisms to reject unwanted information. (Author/DEP)

Preliminary theoretical explanations for visual analysis of stimuli are offered in terms of bilateral nervous systems, handedness and reading, and perceptual strategies. (RB)

A diagnostic study tested the hypothesis that still advertising pictures and television commercials are governed by a basic visual communication principle: that viewers' comprehension and retention of still and moving images depends greatly on the harmonious coexistence of their figure/ground relationships. Ten still images (half in black and…

Human neonates selectively fixated patterns with curved rather than straight contours when the outermost contours differed in this form variable and when quantitative variables were controlled. Data indicated the presence from birth of a discrimination ability basic to later form perception. (Author/ED)

This annotated bibliography containing research on visual perception executed at photopic levels in artificial laboratory situations has been compiled to make information available that can be applied to scotopic perception of natural objects in natural situations. There are 407 reports or studies, published from 1945 through 1964, cited in this…

This paper discusses some methodological, theoretical and physiological issues to be considered in the use of film tests in research relating to visual cognition and memory. One trouble spot in methodology is the use of a square data matrix with an insufficient number of observations in proportion to variables. A second methodological problem…

The relation between type of label and perception of faces was assessed. Sixty-four second and sixth grade Ss were randomly assigned to four experimental conditions in which various kinds of labeling training were associated with four purple and green smiling and frowning faces. Ss then judged the similarity of pairs of the faces. Results revealed…

Two-letter stimulus displays, differing in the magnitude of the horizontal spatial separation between the letters, were presented tachistoscopically to 10 retarded and 1 nonretarded adults. (Author/CL)

The influence of stimulus number and familiarity on judged duration were investigated. Results showed that the number of stimulus elements presented within a given interval affected its perceived duration, although the familiarity of those elements (as defined herein) did not. (Editor/RK)

The article examines evidence of visual impairment caused by excessive amounts of ultraviolet (UV) light. Among considerations when using a source of UV light for vision stimulation are the position of the child and teacher, use of window glass filters or protective glasses, and careful recordkeeping of all UV stimulation. (Author/JW)[

A new theory linking information extraction patterns to the visual perception of direction and extent is presented. Seven demonstration experiments employ predictions from efferent considerations to create a new set of illusions of direction and extent and to demonstrate new predictable variations in the magnitude of some classical illusion…

Reports on three experiments involving 300 six-year old children that investigated the conditions under which young children would produce "separates" as opposed to partial occlusion drawings. (HOD)

Examines, in two experiments, 5-month-old infants' sensitivity to auditory-visual specification of distance and direction of movement. One experiment presented two films with soundtracks in either a match or mismatch condition; the second showed the two films side-by-side with a single soundtrack appropriate to one. Infants demonstrated visual…

Examines an avant-garde illustrated book and suggests that "deviant" books urge a kind of reading that gives visibility to the text and seeks out relationships created between two volumes--the book and its words. (DF)
