Effects Of Multisensory Stop Signals On Sensitivity To Alcohol-Induced Disinhibition In Drinkers With Adhd, Alexandra R. D'Agostino
Effects Of Multisensory Stop Signals On Sensitivity To Alcohol-Induced Disinhibition In Drinkers With Adhd, Alexandra R. D'Agostino
Theses and Dissertations--Psychology
Multisensory environments facilitate behavioral functioning in humans. The redundant signal effect (RSE) refers to the observation that individuals respond more quickly to stimuli when information is presented as multisensory, redundant stimuli rather than as a single stimulus presented to either modality alone. Our studies show that the disinhibiting effects of alcohol are attenuated when stop signals are multisensory versus unisensory. The present study expanded on this research to test the degree to which multisensory stop signals could also attenuate the disinhibiting effects of alcohol in those with attention-deficit hyperactivity disorder (ADHD), a clinical population characterized by poor impulse control. The …
Attentional Bias And Alcohol Abuse, Jessica Jane Weafer
Attentional Bias And Alcohol Abuse, Jessica Jane Weafer
Theses and Dissertations--Psychology
Selective attention towards alcohol-related cues (i.e., “attentional bias”) is thought to reflect increased incentive motivational value of alcohol and alcohol cues acquired through a history of heavy alcohol use, and as such attentional bias is considered to be a clinically relevant factor contributing to alcohol use disorders. This dissertation consists of two studies that investigated specific mechanisms through which attentional bias might serve to promote alcohol abuse. Study 1 compared magnitude of attentional bias in heavy (n = 20) and light (n = 20) drinkers following placebo and two doses of alcohol (0.45 g/kg and 0.65 g/kg). Heavy drinkers displayed …
Polyamine Modulation In Alcoholism: Examination Using A Novel Screening Procedure Designed To Predict Anti-Relapse And Neuroprotective Efficacy, J. Ben Lewis
University of Kentucky Doctoral Dissertations
Alcohol dependence is a major public health concern. Despite the FDA’s approval of multiple anti-relapse drugs, relapse rates remain unacceptably high. Furthermore, cognitive deficits among chronic drinkers are evident and are suggested to contribute to relapse risk. Current evidence suggests that several critical features of alcoholism and alcohol-associated neurodegeneration are mechanistically linked to glutamatergic actions; specifically, they appear positively affected by glutamatergic inhibition, particularly inhibition via polyamine modulation of a subpopulation of n-methyl-d-aspartate receptors. The current project was designed to evaluate the performance of two putative polyamine modulators (JR-220 and CP-101,606) in a variety of screens designed …
