Rumination is a construct that cuts across a variety of disorders, including anxiety and depression. It has been associated with deficits in cognitive control thought to confer risk for psychopathology. One aspect of cognitive control that is especially relevant to the content of ruminative thoughts is error processing. We examined the relation of rumination and 2 electrophysiological indices of error processing, error related negativity (ERN), an early index of error detection, and error positivity (Pe), a later index of error awareness. Consistent with prior work, ERN was negatively correlated with anxiety (i.e., more anxious individuals were characterized by larger ERNs). …

Effects Of Anandamide Administration On Components Of Reward Processing, Howard C. Cromwell
Howard Casey Cromwell
Previous research has implicated the positive modulation of anandamide, an endocannabinoid neurotransmitter,on feeding behavior. Anandamide is particularly noteworthy as it acts as an endogenous ligand of the CB1receptor, the same receptor that is activated by tetrahydrocannabinol, the primary psychoactive component in Cannabis sativa. Cannabis legalization in North America has presented with a need to study endocannabinoid agonists and their effects on behavior. Much has yet to be determined in terms of the role of the endocannabinoid system in decision-making scenarios. The research presented here tested the hypothesis that anandamide wouldaugment motivation and reward processing via appetitive and …
