Influence Of Stress And Cytokinic Profiles On Cognitive Performance In Older Adults, Kerri S. Rawson

USF Tampa Graduate Theses and Dissertations

ABSTRACT

With aging, changes in the immune system, makes cognitive performance, and the prevalence of stressors can lead to poorer overall functioning. Within the immune system, a balance should exist between cytokines regulating Th1 and Th2 immune responses; however, age-related declines in the endocrine and immune systems can disrupt this equilibrium. Several studies report higher levels of Th1 associated cytokines in inflammatory conditions of the brain, whereas fewer studies remark on Th2 associated cytokines and cognitive functioning. Declining cognitive abilities are a common concern that accompanies advancing age and some research has suggested the prevalence and impact of stressors lead …

Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …
