cognitive abilities—concentration and perseverance. Undergraduate
students (N-51) were tested on both a concentration task and a
perseverance task after one of three levels of food deprivation: none, 12
hours, or 24 hours. We predicted that food deprivation would impair both
concentration scores and perseverance time. Food deprivation had no
significant effect on concentration scores, which is consistent with recent
research on the effects of food deprivation (Green et al., 1995; Green
et al., 1997). However, participants in the 12-hour deprivation group
spent significantly less time on the perseverance task than those in both
the control and 24-hour deprivation groups, suggesting that short-term
deprivation may affect some aspects of cognition and not others. |
