✦ Synopsis
In Experiment 2, the spatial frequency channels activated by each display were evaluated by measuring the effect of display adaptation on the contrastsensitivity function. The results suggested that high-RAR screens and hard-copy print activated higherfrequency channels than did Iow-RAR screens. In Experiment 3, significantly better visual search performance was obtained for high-RAR screens and for hard-copy print than for low-RAR screens. It was concluded that screen RAR is an important variable to consider in the design of CRTs.
