Discussed are data concerning a simple visuomotor tracking task, especially the expectations and cognitive representations involved in performing such a task. The task consisted in tracking the horizontal displacement of a target spot on the screen by appropriate forearm rotations. Each subject participated in two sessions: first, at a .8 Hz…

It has been proposed that the ability of a visual noise mask to stop processing of a target stimulus under backward-masking conditions be gauged by its ability to obscure the target when both stimuli are viewed simultaneously. Authors assessed the usefulness of this proposal. (Editor/RK)

Article addressed itself to the questions of which stimuli make up a total conditioned stimulus configuration and what the role is of the period of illumination of the target. (Author/RK)

Differential fixation to novel stimuli was obtained from 4-month-old infants to test the discrepancy hypothesis, which predicts a curvilinear relationship between degree of discrepancy and attention. (ST)

Young children usually prefer to classify objects on the basis of shape rather than color. The present study explored this phenomenon with a stimulus matching test and a component selection test. (ST)

In a study of spatial perspectives, third- and fifth-grade students were asked to coordinate perspectives on single-object and multiple-object arrays. (ST)

The present study was designed to identify sources of information in the human face and to determine how this information is processed by young children in solving problems. (ST)

The development of the ability to associate numerals with sets of appropriate size was studied in children, ages 4 to 5-1/2. (ST)

The present experiment was designed to investigate the influence of label training on the reporduction-recall of visual stimuli and follows in the tradition of the Gestalt memory-for-form literature. (Author)

Presents an investigation of the hypothesis that specific reading disability is attributable to inadequate visual memory. A total of 126 subjects, ages 7-14, who were asked to demonstrate retention of randomly arranged Hebrew letters on three separate occasions, provided no evidence that deficient visual memory is a likely source of reading…

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.

A looming paradigm was used to determine what depth information infants process in addition to that provided by the expansion of a single, closed contour of an object. A total of 18 male and 15 female infants aged 22-48 days watched a film in which the circular elements and inter-element spaces of the projected image alternately expanded and…
