Abstract: | Abstract.— The effects of sleep deprivation (SD) on the reversal rate of the Necker cube and Rubin's Vase-Faces were studied both with instructions to maximize and to minimize the rate. Three viewing conditions were used: Free eye movements, eyes on a fixation point and reversals of an after-image of the figure. SD was found to increase the rate under minimizing instructions and to decrease the rate under maximizing instructions. The results were interpreted in terms of an accelerated satiation process and an impairment of the attentional control. |
