摘要

Two experiments were conducted to examine the effects of video display contrast, image polarity, and absolute luminance on visual search preformance and perference judgements. In a trial, subjects were presented with a target word which they searched for in a subsequent display containing an array of 10 words. Search times, search accuracy, and preference ratings were measured for each factorial combination of the three luminance factors.;Results of the two experiments indicated the following. First, search times leveled off with a display contrast of 4:1 or more. Second, low luminance displays generally led to slower search times than high luminance displays (where high luminance = 10 x low luminance). Third, the low luminance performance decrement was greatest in the low contrast (2:1, 4:1) conditions. Fourth, there were no performance differences found as a function of image polarity. Finally, preference judgements generally agreed with performance measures. The interpretation and implications of these findings were discussed.
