Presents a general overview of various light-related findings with implications for the computer assisted learning environment. Suggests that software developed for instructional purposes incorporate color to maximize visual sensitivity and retention of information while minimizing visual fatigue. (Author/JN)

Discusses positive and negative influences of color on learning/comprehension and attention, influence of color on coding, cues, and context, and effects of color in instructional media. Indicates that although research has not shown color to benefit learning, positive affective results justify continued and even increasing use of color in…

Suggestions are provided for using color television projector systems to demonstrate color mixing. With such a projector, manipulation of the three primary colors can be done by simply covering and uncovering the three separate beams. In addition, projector systems serve as good examples in studying geometrical optics. (Author/JN)

Developmental color perception of 278 four- and eight-year-old Black and White children in three societies was examined in relation to the theories that proximity to the equator and that fundus pigmentation (as measured by skin color) reduce shortwave (blue-green) in comparison to long-wave perception.

Forty-five children, ages seven to eight, were required to catch playground balls of various sizes and colors. The smallest ball (6 inches) was caught significantly better than larger ones. Although the main effect for color was nonsignificant, children caught preferred-color balls significantly better than others. Males caught better than…

Listed are selected resource materials on color vision and the measurement and specification of the stimulus for vision, photometry, and colorimetry. The author's purpose is to equip teachers and students with an understanding of normal and abnormal color vision. References are categorized relative to content level. (Author/DS)

Research on the relationship between color connotations and racial attitudes is reviewed. A similar study conducted among 275 college students in 1975 is also described. Social and political factors which may have influenced changes in color connotations as perceived by Blacks are discussed. (GC)
