Infants represent the acts of others and their own acts in commensurate terms. They can recognize cross-modal equivalences between acts they see others perform and their own felt bodily movements. This recognition of self-other equivalences in action gives rise to interpreting others as having similar psychological states such as perceptions and…

Humans see whole objects from input fragmented in space and time, yet spatiotemporal object perception is poorly understood. The authors propose the theory of spatiotemporal relatability (STR), which describes the visual information and processes that allow visible fragments revealed at different times and places, due to motion and occlusion, to…

The idea of visual complexity, the history of its measurement, and its implications for behavior are reviewed, starting with structuralism and Gestalt psychology at the beginning of the 20th century and ending with visual complexity theory, perceptual learning theory, and neural circuit theory at the beginning of the 21st. Evidence is drawn from…

What happens after visual attention is allocated to an object? Although many theories of attention assume that all of its features are selected and processed, there has been little direct evidence that an irrelevant feature dimension of an attended nontarget is processed. In 5 experiments presented here, the authors used a singleton paradigm to…

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.
