Reminiscence, or an increase in retention scores from a short-to-long-term retention test, has been shown in some previous work to be a significant function of arousal. Previous studies of the effects of color versus black-and-white audiovisual presentations have generally used film or television and have found no facilitating effect of color on learning or achievement. No such studies, however, have specifically studied reminiscence, although there is reason to believe that color would be more arousing than black-and-white and thus should facilitate reminiscence. The present experiment examined reminiscence over one week as a function of color versus black-and-white slide-tape presentations. It was found that the proportion of subjects reminiscing in the color condition was significantly greater (p.05, one-tailed test) than the proportion reminiscing in the black-and-white condition. No contribution of a measure of individual differences in arousal or stimulation seeking was obtained. The relative lack of strength of the color effect was noted, and some design considerations for further research on learning and memory effects of color were outlined. (Author/MC)
