The purpose of this study was to examine the effects on the perceptual processes when the contours of a map are layer tinted with various colors. Data from military officers serving as Ss indicated layer tinting significantly reduced the times to determine altitudes of specific locations on a map. However, layer tinting had a detrimental effect and significantly increased times to determine grid coordinates on the same map.
