Describes the three part system of human vision. Explores the anatomical arrangement of the vision system from the eyes to the brain. Traces the path of various visual signals to their interpretations by the brain. Discusses human visual perception and its implications in art and design. (CW)

Compares estimates of monocular visual resolution of children 6- to 36-months of age with three psychophysical procedures: the Probabilistic Estimation by Sequential Testing (PEST), a modification of the PEST procedure, and the method-of-constant stimuli. (HOD)

This article examines how adults' conditioned responses to objects restrict the range and nature of their perceptions. Maintains that art can transform the experience of context so that the personal and particular reactions can be reclaimed. (JDH)

The record of eye fixations and movements is an objective measure of an individual's involvement with an art object. This review of eye movement research reveals distinct patterns of viewing behavior which are determined by the age of the viewer, the type of visual materials, the nature of the problem confronting the viewer, and the structure of…

This study investigated the ability of first-, third-, and fifth-grade students to perceive similarities and differences in contour and interior pattern of shapes in color drawings. Results showed that with increase of age, attention to contour information was significantly affected by the surrounding contextual information found in the drawings.…

Children's and adolescents' responses to some nonmimetic figures of motion showed that the figures become more effective in indicating direction of motion as age increases; however, at a given age, some are much less effective than others. As indicators of speed, some figures are intrinsically more effective than others. (Author/RM)

Describes preschool children's ability to simultaneously perceive multiple aspects of an object in two experiments during which three- to five-year-olds were asked to describe part/whole pictures. (HOD)

Infants of 12 months were tactually familiarized with either a hard or an elastic substance. Subjects subsequently were shown films of objects moving in patterns characteristic of either hard or elastic objects, and their eye movements were detected. Results suggested that quite young infants detect intermodel invariants specifying some substances…

Discusses the audio and video-recorded longitudinal data from six infants with varying degrees of vision. The findings indicate that there are basic differences in early language, which appear to reflect differences in cognitive development. (SL)

Discusses various issues related to colorblind students performing titrations with visual indicators. Includes tables showing precisions in the titration of a weak acid by colorblind students using phenolphthalein and thymolphthalein and in the titration of a weak base by colorblind persons using methyl red and bromcresol green. (JN)

The effects of stimulus dimension and mode of exploration on preschool children's responses to pattern meanings and unusual uses tasks of original thinking were studied. The 3D tasks generated more responses overall. Visual and haptic exploration combined with 3D was the only condition studied to meet all criteria for construct validity.…

Concludes that viewers of television news tend to focus on the audio and are not disturbed by discontinuity in the video. (FL)

Analysis of the data showed no significant correlation between scores from the two modalities, indicating that knowledge of a person's ability to understand speech in one system provides little information about the same person's ability to understand speech in the other. (Author/CL)

Sixteen students (6-26 years old) with developmental dyslexia or hyperactivity and 16 controls were administered the Peabody Picture Vocabulary Test (PPVT) and the Revised test (PPVT-R). Increased numbers of perceptually loaded plates accounted for a decrease in IQ scores for dyslexic hyperactive Ss on the revised test. (CL)

The author discusses the role of educational "crutches" that help elementary learning disabled children in tasks involving spatial orientation, visual perception, and auditory short-term memory. Teachers are cautioned to observe how children act in different situations and to allow them whatever "crutches" are effective. (CL)
