Zajonc's (1968) "mere exposure" effect was replicated by measuring change in favorability toward black and white college seniors. Following a preexperimental selection of the five most neutral slides for each race by sex category, 40 experimental and 40 control group subjects rated ten black and ten white slides on a pre- and a posttest. The experimental treatment consisted of ten exposure sequences of the 20 slides, whereas the control group performed an inverted alphabet printing task. A repeated measures analysis of variance, conducted on the subjects, favorability ratings for both the pre- and the posttests, supported the hypothesis that a significant attitudinal enhancement will be obtained by white subjects exposed to a slide sequence of blacks and whites. In addition, an analysis of variance on the pretest ratings revealed several significant interactions. An absence of differential demand characteristics for both treatments was indicated by a postexperimental inquiry.
