The Effects Of Reinforcer-Paired Stimuli On Operant Behavior: Review, Demonstration, And Conceptual Analysis, Timothy Lowell Edwards

Masters Theses

The presentation of stimuli that have been paired with reinforcers may function as a motivating operation in that the efficacy of the reinforcers appears to increase and the class of responses that have been historically followed by those reinforcers increases in strength. This phenomenon has important implications for a number of behavioral concerns including drug addiction and eating disorders. A review of the existing literature examining this phenomenon presented herein suggests that the phenomenon is reliable and robust but that it is reinforcer-specific. In the animal study that is subsequently described, rats show a higher proportion of responding on average …

The Dragons In Your Dreams, Jacquelyn Walther

Theses and Dissertations

What if every craving that you ever felt stayed with you forever? Suppose facades couldn’t exist, and what should only be the deepest, densest core of a desire was formed into a mass, a body. Its will matching yours in its physical presence. I make creatures that are embodiments of emotions. In this study I mainly focus on desires and inhibitions surrounding romance. I explore anatomical structures and how material make-up can directly reflect emotional character. In this exploration, the materiality of clay allows for a thorough manipulation of the composition of the creatures. In this I am also able …

Modulation Of Peripheral Taste Function By Glial-Like Taste Cells, Michael S. Sinclair

Open Access Dissertations

Taste is detected by cells of taste buds in the oral cavity. Mammalian taste buds contain three types of cells: receptor, presynaptic, and glial-like. Of these three, glial-like cells are the least studied. Their only known function is that they clear neurotransmitters from the extracellular space. The present work describes two previously undocumented properties of glial-like cells. First, Oxytocin receptor (OXTR) mRNA was detected by RT-PCR in taste tissue of mice. In the taste buds of Oxtr-YFP knockin mice, YFP was seen in glial-like taste cells and other cells immediately outside the taste bud, but no other cells in oral …

Use Of A Clay Modeling Task To Reduce Chocolate Craving., Jackie Andrade, Sally Pears, Jon May, David J. Kavanagh

School of Psychology

Elaborated Intrusion theory (EI theory; Kavanagh, Andrade, & May, 2005) posits two main cognitive components in craving: associative processes that lead to intrusive thoughts about the craved substance or activity, and elaborative processes supporting mental imagery of the substance or activity. We used a novel visuospatial task to test the hypothesis that visual imagery plays a key role in craving. Experiment 1 showed that spending 10 min constructing shapes from modeling clay (plasticine) reduced participants' craving for chocolate compared with spending 10 min 'letting your mind wander'. Increasing the load on verbal working memory using a mental arithmetic task (counting …

Does The Use Of An Oral Lipase Inhibitor (Orlistat) Increase Appetite?, Sandra Boyd

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: To determine whether or not Orlistat ingested prior to a meal causes an increased appetite response.

STUDY DESIGN: A Review of three randomized controlled trials studies from 2003-2008 that were in the English language.

DATA RESOURCES: Randomized controlled trials comparing the effect of Orlistat on satiety were found using PubMed, OVID, and Cochrane databases.

OUTOMES MEASURED: Outcomes measured in the studies were: sensation of appetite, hunger, fullness, nausea, bloating, heartburn, belching, epigastric burning, and prospective food consumption. Each study measured individual patient responses using a VAS (visual analogue scale). Demarchi et al (2004) used a gastric barostat to measure …
