AbstractThis study examined the effects of short-term food deprivation on twocognitive abilities—concentration and perseverance. Undergraduatestudents (N-51) were tested on both a concentration task and aperseverance task after one of three levels of food deprivation: none, 12hours, or 24 hours. We predicted that food deprivation would impair bothconcentration scores and perseverance time. Food deprivation had nosignificant effect on concentration scores, which is consistent with recentresearch on the effects of food deprivation (Green et al., 1995; Greenet al., 1997). However, participants in the 12-hour deprivation groupspent significantly less time on the perseverance task than those in boththe control and 24-hour deprivation groups, suggesting that short-termdeprivation may affect some aspects of cognition and not others.
