The Effects Of Escalated Fentanyl Intake On Decision-Making Dynamics, Trinity Shaver Jan 2023

The Effects Of Escalated Fentanyl Intake On Decision-Making Dynamics, Trinity Shaver

Theses and Dissertations--Psychology

Opioid Use Disorder is characterized partially as a decision-making disorder. Decision-making theories, such as habit theory and relative value theory, have aimed to better understand the shift in preference for drug over other alternatives. In order to compare these two contrasting theories, an allomorphic concurrent choice task will run in tandem with an escalation procedure. Male and female Sprague-Dawley rats were tested for choice differences in an allomorphic choice procedure. Reward dimensions, such as relative reward rate, were manipulated within sessions, and magnitude (remifentanil dose), was manipulated between sessions. To study the effects of escalated fentanyl intake on relative valuation, …


Effects Of Oxycodone And Methylphenidate On Self-Control With Aversive Outcomes, Jeremy Saul Langford Jan 2023

Effects Of Oxycodone And Methylphenidate On Self-Control With Aversive Outcomes, Jeremy Saul Langford

Graduate Theses, Dissertations, and Problem Reports

In the context of choice, one is said to show self-control under numerous conditions in which consideration is given to the delayed outcomes of each option. This can be difficult: both reinforcing and aversive outcomes become less effective as they are increasingly delayed. Several socially significant issues arise from a failure of delayed, aversive outcomes to impact choice, especially when immediate, reinforcing outcomes are available. Identifying the conditions under which choice is sensitive to delayed outcomes is critical to shifting choices toward alternatives in which contact with delayed, aversive outcomes is minimized. Two experiments were conducted with the aim of …


A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot Jan 2022

A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot

Graduate Theses, Dissertations, and Problem Reports

Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …


The Paradoxical Consequences Of Choice: Often Good For The Individual, Perhaps Less So For Society?, Shilpa Madan, Kevin Nanakdewa, Krishna Savani, Hazel Rose Markus Feb 2020

The Paradoxical Consequences Of Choice: Often Good For The Individual, Perhaps Less So For Society?, Shilpa Madan, Kevin Nanakdewa, Krishna Savani, Hazel Rose Markus

Research Collection Lee Kong Chian School Of Business

The proliferation of products and services, together with the rise of social media, affords people the opportunity to make more choices than ever before. However, the requirement to think in terms of choice, or to use a choice mind-set, may have powerful but unexamined consequences for judgment and decision making, both for the chooser and for others. A choice mind-set leads people to engage in cognitive processes of discrimination and separation, to emphasize personal freedom and independent agency, and to focus on themselves rather than others. Reviewing research from social psychology, legal studies, health and nutrition, and consumer behavior, we …


Alternatives: The Video Game. An Assessment Of Bias And Preferences In Uncertain Situations, Vincent Edwards Jan 2020

Alternatives: The Video Game. An Assessment Of Bias And Preferences In Uncertain Situations, Vincent Edwards

Electronic Theses and Dissertations

Going against working assumptions of what is "natural", animals have been observed to "gamble" when choosing between a high-risk choice with a high reward, and a consistent alternative with a low reward that feeds them more over time. The Energy Budget Rule (EBR) claims that animals have a foraging goal they must reach to survive, and each attempt to forage has a cost; under certain conditions, a high risk "gamble" is the best option for survival. The present study attempts to observe human choice behavior in a task that tests EBR and assesses shifts in behavior over time as an …


Neurobehavioral Measurements Of Natural And Opioid Reward Value, Aaron Paul Smith Jan 2019

Neurobehavioral Measurements Of Natural And Opioid Reward Value, Aaron Paul Smith

Theses and Dissertations--Psychology

In the last decade, (non)prescription opioid abuse, opioid use disorder (OUD) diagnoses, and opioid-related overdoses have risen and represent a significant public health concern. One method of understanding OUD is as a disorder of choice that requires choosing opioid rewards at the expense of other nondrug rewards. The characterization of OUD as a disorder of choice is important as it implicates decision- making processes as therapeutic targets, such as the valuation of opioid rewards. However, reward-value measurement and interpretation are traditionally different in substance abuse research compared to related fields such as economics, animal behavior, and neuroeconomics and may be …


Probability Discounting Of Lewis And Fischer 344 Rats: Strain Comparisons At Baseline And Following Acute Administration Of D-Amphetamine, Jenny E. Ozga Jan 2019

Probability Discounting Of Lewis And Fischer 344 Rats: Strain Comparisons At Baseline And Following Acute Administration Of D-Amphetamine, Jenny E. Ozga

Graduate Theses, Dissertations, and Problem Reports

Risky choice can be defined as choice for a larger, uncertain reinforcer over a smaller, certain reinforcer when choosing the smaller alternative maximizes reinforcement. Risky choice is studied using various procedures in the animal laboratory; one such procedure is called probability discounting. There are many variables that contribute to risky decision-making, including biological and pharmacological determinants. The present study assessed both of these variables by evaluating dose-response effects of d-amphetamine on risky choice of Lewis (LEW) and Fischer 344 (F344) rats. The probability-discounting procedure included discrete-trials choices between one food pellet delivered 100% of the time and three food …


Targeting Food Selectivity In Young Children In A Preschool Classroom Using A Multi-Component Treatment Package, Christina Challed Hesley Jan 2019

Targeting Food Selectivity In Young Children In A Preschool Classroom Using A Multi-Component Treatment Package, Christina Challed Hesley

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

The purpose of the study was to evaluate the effectiveness of using a video model, graduated exposure (i.e., touch, smell, try, eat), and positive reinforcement to first increase food exploration, and then increase consumption of non-preferred foods in young children that exhibit food selectivity in a school setting. A multiple probe design across behaviors replicated across participants was used to evaluate the effectiveness of a treatment package. The treatment package consisted of a video model of each target behavior (touch, smell, try, eat) and positive reinforcement which included preferred foods and materials. The results indicated that the treatment package was …


Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel Jan 2018

Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel

Graduate Theses, Dissertations, and Problem Reports

Much of the research in the area of self-control has examined choice between small immediate reinforcers and large delayed reinforcers, but many problems result from situations in which a single choice produces consequences of conflicting valence: Those in which the immediate outcome is reinforcing and the delayed outcome is aversive. Recent research has evaluated how preference for a large reinforcer which is followed by a delayed shock changes as a function of the delay to shock and how the intensity and duration of delayed shock affects the value of a large reinforcer. The present set of experiments investigated how the …


Pigeons Choose To Gamble In A Categorical Discrimination Task, Nathaniel C. Rice, Elizabeth G. E. Kyonka Dec 2017

Pigeons Choose To Gamble In A Categorical Discrimination Task, Nathaniel C. Rice, Elizabeth G. E. Kyonka

Analysis of Gambling Behavior

In slot-machine play, near wins are stimuli that visually approximate winning stimuli but deliver no reinforcers. In two experiments, a categorical discrimination task was embedded in a concurrent chain to investigate how near wins affect preference for probabilistic versus certain food. Pecking in variable-interval initial links produced access to a fixed-ratio (FR) 1-FR 1-FR 1 chain. When all links were red, the chain was a “win” that produced access to food. A “clear loss” chain involved three green stimuli, and in a “near win,” key colors during successive FR 1 links were red, red, and green. In Experiment 1, the …


Motivational Situations Of Choice, Charles N. Elliott, Paul A. Story Sep 2016

Motivational Situations Of Choice, Charles N. Elliott, Paul A. Story

The Kennesaw Journal of Undergraduate Research

The present research explores situations that demonstrate enhancing effects on motivation based on the amount of choice seen by individuals. Individuals who are intrinsically motivated see more choice in certain academic settings, including those that foster self-regulation and autonomy. Extrinsically motivated individuals are predicted to see more promise in reward and external regulation strategies. We identified six separate situations: a free will situation, a learning of materials situation, an instructor feedback situation, an extra credit situation, and two time-based situations. Four of these situations target a certain type of motivation, either intrinsic or extrinsic. The other two situations were used …


Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodríguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens Jan 2016

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodríguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens

Faculty Publications

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …


Public And Private Goal Commitment : Self-Control And Choice, Rebekah L. Layton Jan 2014

Public And Private Goal Commitment : Self-Control And Choice, Rebekah L. Layton

Legacy Theses & Dissertations (2009 - 2024)

Public precommitment to a goal may drive goal achievement. This work explores the effects of public precommitment on goal achievement using the limited-resource model of self-control. Goal commitment which alters future choices available by inflicting a self-imposed cost for giving up is called precommitment. Public commitment to a goal can be viewed as precommitment by imposing a social cost for failure (e.g., anticipated embarrassment). This may facilitate goal pursuit through two processes: First, by shifting the cost earlier in the process via the structural route in which goal-setting processes may deplete self-control resources initially (Studies 1 and 2), while improving …


The Methodology Of The Behavioral Analysis Of Law, Avishalom Tor Nov 2013

The Methodology Of The Behavioral Analysis Of Law, Avishalom Tor

Avishalom Tor

This article examines the behavioral analysis of law, meaning the application of empirical behavioral evidence to legal analysis, which has become increasingly popular in legal scholarship in recent years. Following the introduction in Part I, this Article highlights four central propositions on the subject. The first, developed in Part II, asserts that the efficacy of the law often depends on its accounting for relevant patterns of human behavior, most notably those studied by behavioral decision scientists. This Part therefore reviews important behavioral findings, illustrating their application and relevance to a broad range of legal questions. Part III then argues that …


Sharing: Social Behavior In Situations Of Risk, Stephanie Theresia Stilling Aug 2013

Sharing: Social Behavior In Situations Of Risk, Stephanie Theresia Stilling

Dissertations

The present study will experimentally investigate human cooperation (sharing) in a laboratory foraging task that simulates environmental variability and resource scarcity (shortfall risk). Specifically, it investigates whether a risk-reduction model of sharing developed by evolutionary biologists (derived from a risk-sensitive optimization model known as the energy-budget rule) could predict human cooperative behavior. Participants respond to earn points exchangeable for money when point gains were unpredictable. Failures to acquire sufficient points result in a loss of accumulated earnings (a shortfall). Participants are given the choice between working alone or working with others. The difficulty of meeting the earnings requirement is manipulated …


A Rat Model Of Gambling Behavior And Its Extinction: Effects Of "Win" Probability On Choice In A Concurrent-Chains Procedure, David N. Kearns, Maria A. Gomez-Serrano Jan 2011

A Rat Model Of Gambling Behavior And Its Extinction: Effects Of "Win" Probability On Choice In A Concurrent-Chains Procedure, David N. Kearns, Maria A. Gomez-Serrano

Analysis of Gambling Behavior

Two experiments examined the effects of varying the probability of “wins” within a rat model of gambling. On a concurrent-chains procedure, rats could choose between a “work” lever on which a fixed 20 responses produced a food pellet or a “gamble” lever, where on some trials (“wins”) only one response was required for reinforcement while on other trials 40 responses were required. Despite the fact that the work lever was always associated with the higher overall reinforcement rate, rats frequently chose to respond on the gamble lever. The frequency with which rats chose the gamble lever varied as a function …

Ethnography In Counseling Psychology Research: Possibilities For Application., Muninder Kaur Ahluwalia, Lisa A. Suzuki, Jacqueline S. Mattis, Cherubim A. Quizon Apr 2005

Ethnography In Counseling Psychology Research: Possibilities For Application., Muninder Kaur Ahluwalia, Lisa A. Suzuki, Jacqueline S. Mattis, Cherubim A. Quizon

Department of Counseling Scholarship and Creative Works

The emphasis placed on prolonged engagement, fieldwork, and participant observation has prevented the wide-scale use of ethnography in counseling psychology. This article provides a discussion of ethnography in terms of definition, process, and potential ethical dilemmas. The authors propose that ethnographically informed methods can enhance counseling psychology research conducted with multicultural communities and provide better avenues toward a contextual understanding of diversity as it relates to professional inquiry.
