Describes a perceptual illusion, the Janus mask, for use in introductory psychology demonstrations. Suggests using a motor or videotaped image to rotate the mask, giving the impression that the mask is following a moving observer or oscillating. Recommends the illusion to show that perception is usefully conceptualized as hypothesis testing. (DK)

Presents illustrations of numerous optical illusions which can be used in the classroom to amuse and to stimulate discussion. (MLH)

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)

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 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)

Discusses reading specialists' responsibilities concerning children's vision problems. (MKM)

Identifies some functional vision problems and describes some assessment procedures for determining whether a child needs professional help. (MKM)

The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

This article describes a visual assessment procedure (VAP) which evaluates capacity, attention, and processing (CAP) of infants and preschool children with visual impairments. The two-level battery considers, first, visual capacity and basic visual attention and, second, visual perceptual and cognitive abilities. A theoretical analysis of the…

Discusses research related to identifying early predictors of school success or intelligence. Reports on a study that suggested correlations exist between how babies process information (visual attentiveness) in the first six months of life and the child's performance on intelligence tests in school. (ML)

Most schools teach the triadic color system, utilizing red, blue, and yellow as primary colors. Other systems, such as additive and subtractive color systems, Munsell's Color Notation System, and the Hering Opponent Color Theory, can broaden children's concepts and free them to better choose color in their own work. (IS)

A diagnostic prescriptive approach using the overhead projector in visual perception and perceptual motor activities is described for 11 deaf multiply handicapped behavior disordered students (9 to 12 years old). (CL)

Stereoscopic photo activities for students are described for the purpose of motivating students in earth science. Included also is the necessary equipment for obtaining the three-dimensional effect. (SA)

The study with 34 gifted fifth-grade students found that a concrete sequential approach to developing visual literacy was more effective than an abstract visualization approach. Subjects either received guided visualization or direct instruction on such art concepts as shape, form, line, color, perspective, variety, and unity. (DB)
