Better Together? Effects Of Dyadic Collaboration On Intertemporal Preference, Emily Edgington

Masters Theses, 2020-current

Abstract

Intertemporal choices have been researched extensively in the context of individual choices. However, empirical evidence is absent regarding intertemporal preferences when two individuals collaborate on a choice task. This study aimed to compare the rates of discounting under the condition of dyadic collaboration and individual decisions. Furthermore, this study examined the collaboration sessions in an online video conferencing platform. Results showed a strong, positive correlation between average individual discounting rates and corresponding dyad rates of discounting. The findings of this study should be considered when making intertemporal decisions.

Key Words: delay discounting, group decision-making, online collaboration

The Effects Of Childhood Trauma On Romantic Support And Adult Problem Behavior, Keiva R. Brannigan

Senior Honors Projects, 2020-current

Adverse childhood experiences (ACEs) are a common topic in research investigating outcomes of abused or traumatized children. Previous literature on ACEs have established that high levels of ACEs are associated with both higher levels of problem behaviors in adulthood and lower quality of support in romantic relationships in adolescence/early adulthood. However, the potential for high levels of romantic support and other healthy relationship qualities to act as a buffer against the negative effects of ACEs on later problem behaviors has yet to be addressed in the literature. Thus, the present study utilizes data from an ongoing longitudinal study on social …

Assessing The Utility Of A Brief Abstinence Test To Reduce Smartphone And Social Media Use, Taylor B. Stanley

Masters Theses, 2020-current

The purpose of the current study is to investigate the efficacy of implementing a Brief Abstinence Test (BAT) for reducing smartphone and social media (SM) use among college students. A BAT is a temporally condensed version of contingency management (CM), a reinforcement-based behavioral intervention. Participants (N = 32, males = 6) self-reported using an iPhone updated to iOS 12 and using SM on their iPhones for at least two hours per day. Once enrolled, participants completed an online battery of health-related questionnaires and learned how to capture electronically their smartphone-use data. Participants experienced a BAT for one week, during …

Rapid Demand Curves: Reward Valuation Using Behavioral Economics, Charles Nastos

Masters Theses, 2010-2019

Within the past few decades, the psychological field of operant behaviorism has converged with the field of economics to aid in the description and interpretation of behavior. In doing so, more stringent, empirical methods of measuring and analyzing behavior have been produced. Laboratory experiments with both human and non-human animals have been used to study concepts that are integral to both fields, such as supply and demand, scarcity, and choice behavior. One goal of behavioral-economic research is to establish a demand function; that is, how does a change in the price of a commodity influence changes in its consumption? Consequently, …

Discounting In The Pigeon: Food-Specified Conditioned Reinforcers, Matthew Wolf

Masters Theses, 2010-2019

Discounting has been observed across a wide range of species, procedures, and reinforcers. One of the main differences in the literature is that studies with humans use money (conditioned reinforcer) as the reinforcer being discounted. This is in contrast to studies with non-human animals where the discounted outcomes are usually directly consumable like food and water (primary reinforcers). At present, there is no non-human animal equivalent to money that has been identified in the discounting literature. To further bridge the remaining gaps in the methodology, a common currency is needed to study conditioned reinforcers in the discounting paradigm. An adjusting-amount …

Attentional Processing: Replication And Extension Of Selection Bias As A Predictor Of Intertemporal Choice Behavior, Dylan Rutter

Masters Theses, 2010-2019

Basic underlying mechanisms of discounting delayed rewards remain unclear (Green & Myerson, 2013). There has been evidence that attentional mechanisms (e.g., fixation and fixation duration) could be further investigate processes related to the discounting of delayed rewards (Franco-Watkins, Matteson, & Jackson, 2016). Franco-Watkins et al. (2016) was the first to propose a measure of attentional mechanisms in a discounting paradigm, known as selection bias. The authors found selection bias was positively correlated with choice behavior. The present study replicated selection bias using a titration procedure and Area Under the Curve scores. This study also analyzed selection bias across choice presentations …

The Effects Of Alcohol Priming And Alcohol-Related Cues On Subsequent Alcohol Preferences, Kathleen R. Owens

Masters Theses, 2010-2019

The purpose of the current study was to investigate the effects of alcohol priming and alcohol-related cues on subsequent alcohol preferences. Researchers assigned randomly 35 university students to 1 of 3 conditions: alcohol delivered in a red disposable plastic cup (AC; alcohol cue; n = 12), alcohol delivered in a cafeteria cup (AN; neutral cue; n = 11), or alcohol placebo (P; n = 12) delivered in a red disposable plastic cup. Participants consumed their assigned beverages, and then completed the Multiple Choice Procedure (MCP), a procedure that allows participants to make discrete choices between a standard alcoholic beverage and …

The Roles Of Race And Empathy On Contagious Yawning, Daroon M. Jalil

Senior Honors Projects, 2010-2019

Social Psychologists often consider race to be a marker of in-group or out-group status. When looking at race, implicit bias can take forms that are more subtle than outwards racism. Two research questions were asked in this study to better understand the psychology behind racial issues. The first question was if the number of contagious yawns (CY) a person experiences depends on the race of the stimuli being viewed. Contagiously yawning more to in-group members is a phenomena seen in chimpanzees, but has not been studied in humans in a racial context. Black and white males and females were recruited …

Sleep Deprivation And Voluntary Alcohol Consumption In Adult Rats, Charles M. Cowan Ii

Masters Theses, 2010-2019

Alcohol is a psychoactive drug with a large userbase among adults across the globe. However, alcohol use also reduces the quality of sleep in the user. Historically, research has focused on the effects of alcohol on sleep architecture, but recent research has started to examine the effects of sleep deprivation on alcohol consumption. This research examines the effects of sleep deprivation on voluntary alcohol consumption in adult rats. Twelve Sprague Dawley rats were given ad libitum access to food, alcohol (7% solution), and water for the duration of this study. Subjects were then placed into non-moving forced exercise wheels to …

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler

Senior Honors Projects, 2010-2019

Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

Cultivating Empathy In Middle School Students Through Narrative Fiction, Kane M. Hamilton

Educational Specialist, 2009-2019

The purpose of this study was to investigate whether reading narrative fiction can potentiate empathy in middle school students. Participants were randomly assigned to two groups: narrative fiction group and expository nonfiction group. Participants in the narrative fiction group were asked to read a passage from a novel selected from the 5^th grade Common Core reading curriculum. Participants in the expository nonfiction group were asked to read a passage from a science book from the 5^th grade Common Core science curriculum. Pretest and posttest data were collected using the Interpersonal Reactivity Index (IRI). Results of this study indicate …

Interteaching: Types Of Prep Guide Questions And Their Effect On Student Quiz Performance, Verena S. Bethke

Masters Theses, 2010-2019

Although previous research indicates that interteaching is an effective alternative to more traditional teaching approaches, not many component analyses of the method exist. For example, although researchers have shown that the prep guide component contributes to the effectiveness of interteaching, no research has directly examined how the content of the prep guides affects learning. The current lab-based study investigated whether having prep guides consisting of lower-level or higher-level questions impacted students’ subsequent quiz performance. We found no significant differences in quiz performance between the two conditions, but several extraneous factors may have impacted the results.

Delay And Probabilistic Discounting Of Alcoholic Beverages, Frank L. Galante

Senior Honors Projects, 2010-2019

Discounting tasks were used to determine the degree to which college undergraduates discounted delayed and probabilistic alcoholic beverages. Tasks were framed in terms of gains (i.e.,obtaining a hypothetical amount of alcohol) and losses (i.e., losing a hypothetical amount of alcohol). In all gain and loss conditions, discounting was evident and was generally well described by a hyperboloid function. Gains were discounted more steeply then losses. There were no correlations between the median delay gain discounting rates and the median delay loss discounting rates. Likewise, there were no correlations between the median probabilistic gain discounting rates and the median probabilistic loss …

Judging Laura, Rebecca E. Richardson

Senior Honors Projects, 2010-2019

Laura Audax is a sixteen-year-old girl who has an interesting set of characteristics. She is a dynamic mixture of compassion, stubbornness, brilliance, recklessness, imagination, and arrogance. The way the world understands these personality traits has transformed and evolved over time. If a girl like Laura lived in four different time periods, society would react differently to her in each era, but the overall question is how different these reactions really are. Does the definition of what makes certain personality traits “good” or “bad” change over time?

The following four stories take place in 1850, 1920, 2015, and 2100 respectively, and …

Delay Discounting: Are Magnitude Effects Moderated By Domain Effects?, David A. Williams Jr.

Masters Theses, 2010-2019

Delay discounting is a phenomenon wherein a commodity loses its value as the delay to its receipt increases. It may be conceptualized as a measure of patience, or impatience. There are several aspects of a commodity that contribute to its loss in value, in addition to the delay to its receipt. Specifically, there are differential rates in delay discounting across commodity types (domain effects) and commodity amounts (magnitude effects). Interestingly, magnitude effects occur almost exclusively in relation to a particular commodity type: monetary rewards. The present study sought to isolate magnitude effects from a particular quality of monetary rewards: fungibility. …
