This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of this study is to examine the effects of sleep deprivation on decision-making and impulse control. This study will investigate the effects of sleep deprivation on several tasks that are considered to be measures of impulsive behavior, including measures of delay discounting, risk-taking, behavioral inhibition, and attention. Impulsive behavior is highly relevant to substance abuse, because events that increase impulsive behavior may increase risk of relapse among abstinent drug users. We hypothesize that subjects deprived of sleep for overnight will perform more impulsively the following morning and evening when tested on delay discounting, risk-taking, behavioral inhibition, and attention tasks.
