Theses and Dissertations
Obesity has reached epidemic proportions in the United States and has become an increasing public health concern for developed nations. Haploinsufficiency of melanocortin receptor 4 has been identified as the single most common monogenetic cause of obesity in humans. Using the MC4R +/- haploinsufficient rat, we sought to determine potential alterations in body weight and morphology, locomotor activity, sucrose concentration preference, and progressive-ratio operant testing in a dietary-induced obesity environment. Rats were placed on four separate diets corresponding to 1.7% saturated fat with 12.2% total kcal/fat, 6% saturated fat with a 40% total kcal/fat, 12% saturated fat with a 40% …

Generalization Of Fear Effects In Reinstatement To A Discrete Stimulus, Lauren Best
USC Aiken Psychology Theses
The purpose of this study was to investigate generalization of reinstated fear effects to a discrete stimulus. McAllister and McAllister (2006) reported that reinstated fear could generalize over time to similar contexts. The present study aimed to determine if reinstated fear could generalize to similar or different stimuli than conditioning after a long delay between reinstatement and testing. Rat subjects were randomly assigned to six groups (n = 10) which received conditioning and extinction to a 3000 Hz tone. Reinstatement conditioning was then conducted with either the same, similar, or different CS as used in conditioning. Testing for reinstated fear …
