Health Anxiety And Cognition: Chronic Awareness Of Health Concerns Or Situational Activation Of Latent Dysfunctional Assumptions About Illness?, Desmon Craig Mitchell
Health Anxiety And Cognition: Chronic Awareness Of Health Concerns Or Situational Activation Of Latent Dysfunctional Assumptions About Illness?, Desmon Craig Mitchell
Dissertations
Rationale: This study investigated if health anxious individuals have chronically aroused illness-related concerns or if these concerns remain latent, only to be activated when first primed by illness-related stimuli. To test these alternatives this study examined whether participants, with varying levels of health anxiety, differed as to their (a) performance on an emotional Stroop task that included health-related words, (b) memory tasks (free recall and recognition tasks), and (c) the participants' dream content, after either being exposed, or not exposed, to an illness-related trigger. Hypotheses: If illness concerns are chronically activated in health anxious individuals, then participants will perform worse …

Converging lines of research have implicated a causal relationship between oligomers of amyloid-β and the cognitive impairments associated with Alzheimer's disease (AD); however, very few studies have provided direct experimental evidence of this relationship and none of those studies have used an established model of working memory. The present study used an established model of working memory, the radial-arm maze, to examine the effects of amyloid-β oligomers on the memory of two groups of rats. The experimental group received ICV injections of the culture media (CM) of Chinese Hamster Ovary (CHO) cells transfected with a human mutation of APP containing …
