How Sleep Deprivation Affects Psychological Variables Related to College Students Cognitive Performance Jenny R. Downs Fall07, PSY 1513 41 General Psychology (MSVCC) (2575) Sleep deprivation is very common for college students. A pattern is usually developed with sleep deprivation peaking during the week and even more during exam periods. Performance levels are significantly lower during these periods even though the students beleived that their performance was better. Many studies have been conducted to try to evaluate the effects of sleep deprivation on cognitive performance and on psychological variables related to cognitive performance in college students. The study in this reading included sixty-five volunteers.

The participants mood was evaluated using the Profile of Mood States or POMS. On the Profile of Mood States scale, current mood states were listed using sixty-five words. The students could rate their current mood on a scale from zero to seven. The higher the number represented the greater the frequency. The findings concluded that only confusion and fatigue were highly affected by sleep deprivation. These aspects caused a significant drop in performance of task completion. Sleep deprivation was not shown to have an effect on task motivation. Research shows that participants acknowledge lower performance levels and increase the effort being put into a task to try to compensate for the lower performance levels. Rewards were offered in one study for better performance. An increase of effort was reported but the increased effort reportedly had no effect on actual performance. Therefore, even though additional effort may be put into a project it is concluded to have no effect on decreased performance levels. Off-task cognitions are thoughts that distract concentration instead of being directed at the current task. Off-task cognitions are usually either negative or un-related thoughts that cause a person to not be able to fully focus on the task at hand.

Theoretical Basis of Study: Psychological mechanisms prevent people from reliving aversive experiences to their truest extremes, creating fewer aversive expectations.
