The Balloon Analogue Risk Task And Behavioral Correlates In Pigeons, Aaron P. Smith Jan 2015

The Balloon Analogue Risk Task And Behavioral Correlates In Pigeons, Aaron P. Smith

Theses and Dissertations--Psychology

Individuals experience risk ubiquitously, but measuring risk taking is difficult. The balloon analogue risk task (BART) was developed in order to assess risk taking through having subjects press a key that accrues reward but also risk losing all reward with each press. In humans, greater responding in this task is associated with other maladaptive risk taking behaviors. The present research modeled this relationship in pigeons due to their previously shown propensity towards risk taking behavior. Experiment 1 used an unsignaled balloon task in which losing could only occur after 5 pecks. Results showed below optimal performance with greater pecks associated …


Effects Of Headings On Processing Of Audio Texts, Hung-Tao Chen Jan 2015

Effects Of Headings On Processing Of Audio Texts, Hung-Tao Chen

Theses and Dissertations--Psychology

Text-to-speech devices often do a poor job of translating signals such as headings from visual into audio mode. Previous research studies have attempted to address this problem but these studies have mainly used heading detection tasks. The current study seeks to investigate 1) whether listeners find the presence of audio headings useful in natural learning tasks, and 2) the type of heading rendering that is most useful in natural learning tasks. The three learning tasks in this study include note-taking, cued recall, and knowledge transfer. Results from this study reveal that listeners find audio headings useful in the note-taking task. …


The Effects Of Alcohol-Related Visual Stimuli On Inhibitory Control And Attentional Bias: Testing The Roles Of Classical Conditioning And Semantic Priming, Ramey G. Monem Jan 2015

The Effects Of Alcohol-Related Visual Stimuli On Inhibitory Control And Attentional Bias: Testing The Roles Of Classical Conditioning And Semantic Priming, Ramey G. Monem

Theses and Dissertations--Psychology

Alcohol research has shown that alcohol-related stimuli can disrupt behavioral control and attract more attention in alcohol drinkers. Stimuli typically used in tasks assessing these mechanisms are likely representative of an individual's history. Responses to visual stimuli that no longer closely resemble an individual's history may help shed light on whether these behaviors are due to classical conditioning or processes such as semantic priming. Hypotheses were tested using typical visual stimuli and modified, abstract versions in these tasks. 41 participants were exposed to these stimuli types while using a visual dot probe task. The difference in degree of attentional bias …


Acute Effects Of Alcohol On Simulated Driving Performance And Self-Perceptions Of Impairment In Dui Offenders, Nicholas A. Van Dyke Jan 2014

Acute Effects Of Alcohol On Simulated Driving Performance And Self-Perceptions Of Impairment In Dui Offenders, Nicholas A. Van Dyke

Theses and Dissertations--Psychology

Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, and traffic tickets (Evans, 2004). To date, no research has examined specific self-regulatory mechanisms of the DUI driver under a dose of alcohol that might underlie risky driving behavior. The present study examined the degree to which DUI drivers display an increased sensitivity to the acute impairing effects of alcohol on driving performance and overestimate their driving fitness following alcohol consumption. Adult drivers with a history of DUI and a demographically-matched group of control drivers without a DUI were tested following …


Emotion, Community Development, And The Physical Environment: An Experimental Investigation Of Measurements, George E. Boone Jan 2013

Emotion, Community Development, And The Physical Environment: An Experimental Investigation Of Measurements, George E. Boone

Theses and Dissertations--Community & Leadership Development

A wide range of research fields have studied how emotions and behavior are affected by the physical environment. This gestalt theorist approach of experimental research as well seeks to measure emotion (using the valence-arousal scale) and micro-scale community development interactions when weighted physical environment factors are adjusted. Community development (CD) interactions at the micro-scale have received but slight attention from scholars in the CD research field and this study aims partially to investigate developing objective measures from social observations. CD interactions from recordings along with self-reported emotion through surveys in four quasi-experimental groups (where the environments were constructed based on …


Does Botox Buffer The Negative Effects Of Social Rejection?: A Test Of The Facial Feedback Hypothesis, Vicki Sharif Jan 2013

Does Botox Buffer The Negative Effects Of Social Rejection?: A Test Of The Facial Feedback Hypothesis, Vicki Sharif

Theses and Dissertations--Psychology

Can a common facial cosmetic procedure buffer against the negative impact of adverse social interactions? This pilot tested the hypothesis that an injection of botulinum toxin (Botox) to the corrugator supercilii muscles used in anger, compared to a placebo injection to the same location, will reduce the impact of social rejection on mood, self-esteem, control, meaningful existence, and aggression. Freezing facial musculature was hypothesized to alter the first physical signal of negative emotional reactions, thereby reducing the impact of social rejection on distress and aggression. This was the first study using Botox to examine the effects of reduced facial feedback …


Characterizing Consumption, Dependence, And The Role Of Glucocorticoids In An Animal Model Of Voluntary Ethanol Consumption, Lynda Sharrett-Field Jan 2013

Characterizing Consumption, Dependence, And The Role Of Glucocorticoids In An Animal Model Of Voluntary Ethanol Consumption, Lynda Sharrett-Field

Theses and Dissertations--Psychology

Alcohol abuse disorders (AUD) represent a serious worldwide health problem with far reaching social, financial, and interpersonal implications. One of the most devastating facets of these disorders is the propensity to relapse following periods of abstinence. Ethanol withdrawal (EWD) is believed to promote relapse by increasing anxiety and craving, and may contribute to the development of cognitive decline associated with long-term dependence. Clinical data suggest that stress also plays a main role in both the development of AUD as well as relapse to drinking. As a physiological stressor, EtOH elevates levels of stress hormones (cortisol in humans, corticosterone (CORT) in …
