A study was conducted to investigate the comprehensibility of microcomputer-generated color graphics that are displayed on monochromatic monitors. Subjects were 64 second, third, and fourth graders who were randomly assigned to one of two conditions. Children in the first treatment were asked to identify, on a monochrome monitor, a figure that was initially presented in its original form and then as a redesigned, more distinguishable figure with greater figure/ground contrast created by substituting colors that utilized pixel patterns to provide contrast in the monochromatic display. The order of picture presentation was reversed for the children in the second treatment. Analysis of variance showed a significant main effect for the treatment variable: subjects in Treatment II recognized the figure more frequently than subjects in Treatment I. Results indicate that: (1) microcomputer-generated graphics intended for color presentation but displayed on monochromatic monitors may not have sufficient figure/ground contrast; (2) insufficient figure/ground contrast may adversely affect picture comprehension; and (3) younger children, at least through fourth grade, seem to lack the necessary perceptual maturity to overcome the effects of poorly discernible figures on a monochromatic green screen. A list of references and three data tables complete the document. (JB)
