Abstract

The purpose of these present experiments is to find out whether the exposure duration and brightness have any effect on visual memory performance. Both exposure duration (0.5 sec, 1.0 sec, 1.5 sec, 2.0 sec, and 2.5 sec) and brightness (30lumen, 60lumen, 90lumen, 120lumen, and 150lumen) are varied in five ways. Both of the two experiments were conducted with the help of thirty random participants who were selected following a simple random sampling technique. One-factor repeated measures design was used to analyze the data. Collected data were analyzed by one-way repeated measures ANOVA to investigate the effects of exposure duration and brightness on visual memory performance. Post-hoc pairwise comparisons (LSDs Method) were carried out for visual memory performance concerning exposure duration and brightness. The ANOVA results represented that there was an effect of exposure duration and brightness on visual memory performance. Moreover, the post-hoc tests indicated that visual memory performance improved with the increase in both exposure duration and brightness.
