Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

The performance of 20 hyperactive and 26 comparison elementary-school boys on a spelling recognition task found that color facilitates attention to detail. Hyperactive children who practiced the task with all black letters first and color added later out-performed comparison children. (Author/JDD)

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)

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)

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)

Describes experiments which focus on the perception of three dimensions. Discusses the cues about distance and depth and the role they have in perceptions of three dimensions. Evaluates the effect of color on the illusion on depth. (ML)

The article reviews three studies (EC 600 064-066) evaluating the effectiveness of using Irlen tinted lenses or overlays with reading-disabled persons. It is concluded that carefully designed and controlled studies do not currently lend support to the Irlen hypothesis. (DB)

Discusses children's ideas about colored objects and colored shadows, with special attention to the organization of these ideas into mental models. The clarification of these models provides instructional tools that serve to assess and confront students' naive conceptions. Subjects were visitors to a science museum who engaged in interactive…

Reading-disabled children (n=92) were classified as either scotopic or nonscotopic using the Irlen Differential Perceptual Schedule. Use of either colored or clear overlays over reading material resulted in improved reading rate, accuracy, and comprehension when scotopic children read with the preferred colored overlay filter. Nonscotopic children…

Students explore three-dimensional properties by creating red and green wall decorations related to Christmas. Students examine why images seem to vibrate when red and green pieces are small and close together. Instructions to conduct the activity and construct 3-D glasses are given. (MDH)

Uses a projector, a prism, and two screens to demonstrate the composition of white light and detect color. (MDH)

Described is an color-making activity where students use food coloring, eyedroppers, and water to make various colored solutions. Included are the needed materials and procedures. Students are asked to write up the formulas for making their favorite color. (KR)

Provides background theory and an experiment relating to chemometrics. Describes the phenomenon where solutions are dichromatic or dichromic. Discusses the difficulty students have in describing such solutions that appear to be several different colors at the same time. (TW)

Describes a corrective method of color adaptation designed to allow most, if not all, individuals to participate in the learning process as well as social and work-related environments. Provides a concise summation of facts and theories concerning color deficiency. Includes anatomical drawings, graphs, and statistical data. (MJP)

This manual contains a work sample intended to assess a handicapped student's ability to see likenesses or differences in colors or shades, identifying or matching certain colors, and selecting colors that go together. Section 1 describes the assessment and lists related occupations and DOT codes. Instructions to the evaluator are provided in the…
