Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills
Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills
Department of Psychology: Dissertations, Theses, and Student Research
The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …

A Quantitative Analysis Of The Value-Enhancing Effects Of Nicotine, Bupropion, And Varenicline In Male And Female Rats, Scott Barrett
Department of Psychology: Dissertations, Theses, and Student Research
Smoking and tobacco dependence are serious health concerns in the United States and globally. Reward via the pharmacological effects of nicotine are believed to be the principal motivating factor that drive tobacco dependence. Research reveals differences in sensitivity between males and females to the motivational effects of nicotine in tobacco use. Enhancement of reinforcement value of non-nicotine rewards contributes to overall nicotine reward. Similar value-enhancing effects have been observed by the two most commonly prescribed smoking cessation aids, bupropion and varenicline. The present dissertation investigated the value-enhancing effects of nicotine, bupropion and varenicline in both male and female rats using …
