The effects of classical factors, such as symbol geometry, symbol brightness, and brightness contrast, upon the legibility of numerals and capital letters are discussed. Included is a consideration of the literature of the last few decades relevant to the specification of acceptable operator performance criteria which must be met by a given…

In this study, developmental changes in duration of the icon (visual sensory store) were investigated with three converging tachistoscopic tasks. (1) Stimulus interuption detection (SID), a variation of the two-flash threshold method, was performed by 29 first- and 32 fifth-graders, and 32 undergraduates. Icon duration was estimated by stimulus…

Accurate interpretation of visual images involves the learning of methods for representing three-dimensional reality on a two-dimensional surface. There are many instances where a given culture exercises its iconic expression. Discussion and comparison of cultural differences is presented and illustrated. (Author/JEG)

This experiment was designed to determine whether children's inability to discriminate mirror-image oblique lines is a function of encoding in memory the left-right orientation or the degree of slope of an oblique line. (Author/SB)

Presents an overview of some of the major concerns for teachers of Image Study in higher education and offers examples of image sets useful for concept teaching. (MH)

Offers a brief student analysis of the visual elements which compose the front pages of two daily British newspapers in a single day. (MH)

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 6-year-olds from a variety of socioeconomic backgrounds. (Author/MS)

From experiments showing that subjects differentially attend to parts of the visual field, psychologists have inferred a limitation on human visual information processing capacity. The model presented describes an optimal way to allocate a limited quantity of "cognitive resources", "attention" or "mental effort". An experiment tests this model.…

Infants were tested in three studies of the acquisition and long-term retention of category-specific information. Results document retention of category-specific information after intervals of two weeks. (PCB)

Synthesizes existing knowledge regarding the communication effects of animation and empirically assesses some of these effects. Results of this confirm that animation can be a viable method of advertising. (SRT)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Measures the phenomenal and the functional durations of visual stimuli differing in informational value. (Author/RK)

Infants ranging from 6 to 12 months were randomly assigned to one of three conditions: (1) allowed to look at a specified object, (2) allowed to look at and manipulate it, or (3) allowed to look at the object and to manipulate the transparent box in which it was encased. (JMB)
