The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe
The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe
Masters Theses, 2010-2019
The relation between chronic sleep restriction and performance on the Psychomotor Vigilance Task (PVT) have been well documented in the human literature, with chronic sleep restriction as little as 7 hours per night resulting in significant impairment in sustained attention performance measured via the PVT. Recently, an analogous version of the human PVT has been developed for use with rodent models (rPVT). Recent studies have measured the effects of sleep restriction on rPVT performance, citing similar results found in the human literature. However, few studies to date have directly examined the role of adenosine accumulation during sleep deprivation in producing …
The Effects Of Caffeine And Rapid Eye Movement (Rem) Sleep Deprivation On Free Operant Responding Under A Vi 30-S Schedule Of Reinforcement, Curtis Allen Bradley
The Effects Of Caffeine And Rapid Eye Movement (Rem) Sleep Deprivation On Free Operant Responding Under A Vi 30-S Schedule Of Reinforcement, Curtis Allen Bradley
Masters Theses, 2010-2019
Past research has shown that the effects of 96 hr of Rapid Eye Movement Sleep Deprivation (REMSD) on positively reinforced behavior is dependent upon the schedule of reinforcement maintaining the behavior. One one hand, lean schedules of reinforcement after REMSD maintained low rates of behavior. On the other hand, rich schedules of reinforcement after REMSD maintained behavior at baseline levels. Other research has shown that the use of stimulants reversed the effects of REMSD on operant tasks. The current study investigated the effects of caffeine on rats’ lever pressing after 96-hr REMSD. During baseline, doses of vehicle were administered 15 …
Assessing The Utility Of A Brief Abstinence Test For Initiating Caffeine Abstinence, Bradley T. Joachim
Assessing The Utility Of A Brief Abstinence Test For Initiating Caffeine Abstinence, Bradley T. Joachim
Masters Theses, 2010-2019
Caffeine is the most commonly consumed drug in the world. Although its effects are relatively mild when consumed in moderate amounts, there exist cases where caffeine use is problematic. Currently no behavioral intervention for problematic caffeine consumption exists in which caffeine use is verified beyond self-reports. No measures of caffeine dependence and withdrawal exist either. The current study examined the viability of contingency management, an empirically supported behavioral intervention for reducing drug use, for initiating abstinence from caffeine consumption among college students of varying levels of use, as well as validity evidence for novel measures of caffeine dependence and withdrawal. …
The Effects Of Caffeine On Delay Discounting In Humans, Andrew Dylan Markham
The Effects Of Caffeine On Delay Discounting In Humans, Andrew Dylan Markham
Masters Theses, 2010-2019
A behavioral form of impulsivity, delay discounting, has been used to examine the effects of drug consumption on individuals' abilities to delay gratification. However, delay discounting has not been used to examine one of the most commonly used drugs in the world, caffeine. Nor has delay discounting been used to examine the effects of drug influence on impulsivity. This study examined the influence of 200 mg caffeine on delay discounting in a collegiate sample. 15 participants underwent two experimental sessions: a caffeine condition and a placebo condition. Although participants were more impulsive under caffeine than under placebo, this trend was …
