Effects Of Early-Adolescent, Mid-Adolescent, Or Adult Stress On Morphine Conditioned Place Preference, Chloe Shields

Senior Theses

In light of previous work demonstrating that stress can increase subjective drug reward in adult rats, the present study investigated the influence of stress on morphine conditioned place preference (CPP) in early-adolescent, mid-adolescent, and adult male Sprague-Dawley rats. Subjects in each age group were assigned to either a no stress condition or a stress condition in which they were exposed to an unpredictable eight-day schedule of elevated platform and synthetic fox odor stressors. Place conditioning then evaluated subjective morphine reward in all animals. Using a biased procedure, subjects were assigned to receive morphine on the initially non-preferred side of the …

Differential Effects Of Methylenedioxypyrovalerone (Mdpv) And Mephedrone In Rats Trained To Discriminate Mdma Or A D-Amphetamine+Mdma Mixture, Eric Louis Harvey

Masters Theses

Recent reports on the abuse of novel synthetic cathinone derivatives call attention to serious public health risks of these substances. In response to this concern, a growing body of preclinical research has characterized the psychopharmacology of these substances, particularly mephedrone (MEPH) or methylenedioxypyrovalerone (MDPV), noting their similarities to MDMA and cocaine. The present study employed drug discrimination methodology to assess the discriminative stimulus effects of MEPH and MDPV in male Sprague-Dawley rats trained to discriminate 1.5 mg/kg 3,4 methylenedioxymethamphetamine (MDMA) or a mixture of 1.5 mg/kg MDMA and 0.5 mg/kg d-amphetamine (MDMA+AMPH). After establishing dose response functions with each training …

Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann

Masters Theses

In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

An Investigation Of Short-Term Memory Functioning In A Neurodevelopmental Rat Model Of Schizophrenia, Ashley M. Moyett

Seton Hall University Dissertations and Theses (ETDs)

Schizophrenia is a debilitating disorder characterized by positive, negative, and cognitive symptoms. Cognitive deficits affect one’s learning and memory due to a dysfunction in the brain, inhibiting a normal functioning life. The self-medicating hypothesis states that ninety percent of people with schizophrenia smoke, because nicotine use improves these cognitive deficits. The cytokine hypothesis states that inflammation due to prenatal infection is associated with schizophrenia. These increased proinflamatory cytokines can damage the brains of the fetuses, which can cause schizophrenic-like symptoms in rats. The present study used Lipopolysaccharides to activate the cytokine-mediated inflammatory response injected into pregnant dams. A T-maze was …

Does Thin Always Sell? The Moderating Role Of Thin Ideal Internalization On Advertising Effectiveness, James A. Roberts, Chloe' A. Roberts

Atlantic Marketing Journal

Much of the current focus on the use of ultra-thin models in fashion magazines can be attributed to Madison Avenue which still operates under a “Thin Sells” ethos. Research to date, however, has provided equivocal evidence of the efficacy of thin models in advertising (Yu 2014). The present study’s two related objectives include: (1) determining whether model size has an impact on advertising effectiveness, and (2) if internalization of the thin ideal moderates this relationship. Study results suggest model size in fashion advertisements has no main effect on advertising effectiveness. Additionally, thin ideal internalization moderates the model size – advertising …

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …

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 …

The Effects Of Tylenol On Non-Social Emotional Memory, Renato Puga

Undergraduate Honors Thesis Collection

The present study proposes utilizing a slide-show presentation analogous to the one employed in Puga, Spelman, and Bohannon (2014). However, a new series of precritical, critical, and post-critical slides will be utilized, counterbalancing perceptuallycentral/peripheral items across all ofthem as well as counterbalancing the pre-critical and post-critical slides. The ultimate goal of this manipulation is twofold: To provide a strong methodological scenario in which (1) the "preceding information effect" found in Puga, Atkinson, and Bohannon (2012) as well as (2) the acetaminophen-post critical effect found in Puga, Spelman and Bohannon (2014) can both be re-tested and solidified.

Paradoxical Interaction Between Ocular Activity, Perception, And Decision Confidence At The Threshold Of Vision, Aaron Schurger

Psychology Faculty Articles and Research

In humans and some other species perceptual decision-making is complemented by the ability to make confidence judgements about the certainty of sensory evidence. While both forms of decision process have been studied empirically, the precise relationship between them remains poorly understood. We performed an experiment that combined a perceptual decision-making task (identifying the category of a faint visual stimulus) with a confidence-judgement task (wagering on the accuracy of each perceptual decision). The visual stimulation paradigm required steady fixation, so we used eye-tracking to control for stray eye movements. Our data analyses revealed an unexpected and counterintuitive interaction between the steadiness …

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. …

Mass Shootings And Mental Illness Perception, Sierra M. Korb

Renée Crown University Honors Thesis Projects - All

This study focused on the relationship between mass shootings and mental illness stigma. Specifically, this study looks at how learning about mass shootings affects the extent to which people with mental illness are stigmatized. Participants were asked to read a short story and then answer survey questions about their opinions of the mentally ill. The main finding of this study was that participant’s preferred greater social distance from people with mental illness after learning about mass shootings, even when it was not explicitly mentioned that the shooter was a person with mental illness.

Illusory Correlations In Mental Illness Stigma, Katrina Aberizk

Renée Crown University Honors Thesis Projects - All

The purpose of this research is to examine people’s readiness to form an association between those diagnosed with a mental health condition and negative behavior in the absence of objective evidence for that association. The research expands on a traditional illusory correlation paradigm to include social group information and two types of negative behavioral statements. The traditional paradigm exposes research participants to a series of statements describing the behaviors of members of two different social groups, including desirable and undesirable behaviors, and participants are then required to recall behavioral information and rank members of both groups on a series of …

The Effects Of Descriptive And Injunctive Peer Norms On Young Adult Alcohol Use, Samantha Paige Detore

Renée Crown University Honors Thesis Projects - All

Descriptive peer norms refer to one’s perception of their peer’s alcohol use, while injunctive peer norms refer to one’s perception of their peer’s approval of alcohol use. Current literature has found that both norms are positively associated with alcohol use among young adults, but it remains unknown whether one norm has a greater influence on alcohol use than the other. The purpose of the current study was to explore this gap in the literature and examine the relative influence of both descriptive and injunctive norms on alcohol consumption. One hundred Caucasian, moderate-heavy drinking young adults completed a baseline questionnaire assessing …

Expanding Openness: The Effect Of Actor Emotional Expression On Audience Openness To Experience, Amalia Golomb-Leavitt

Renée Crown University Honors Thesis Projects - All

Commonly regarded as one of the Big Five domains of personality, openness to experience has the social potential to deepen group connection, increase team growth and performance, and strengthen diverse relationships. In the current study I hypothesize that emotional expression on the part of an actor has the potential to increase the levels of openness to experience of the audience. To test this hypothesis, I administered the Big Five Inventory (BFI-44) to assess baseline levels of openness to experience, randomly assigned participants to view either three videos high in levels of emotional expressivity or three videos low in emotional expressivity, …

The Psychology Of Cyberbullying As Seen Through The University Of Rhode Island, Meaghan Rose Costello

Senior Honors Projects

Cyberbullying is among the most common forms of bullying in today’s American society. There has been an increase in communication through social media, texting, and other forms of technology, as well as a decrease in ‘real-life’ and interpersonal communication. Technological advances have facilitated indirect and passive aggressive forms of harassment on the internet. Many people know someone who has experienced cyberbullying, or have experienced it themselves. Bullying in general receives tremendous attention—with nonprofit groups on a mission to spread awareness and schools actively outlining detailed policies against it, children grow up understanding its repercussions. However, this form of bullying has …

The Effect Of Forewarning On Suggestibility: Does It Depend On Working Memory Capacity?, William Barrett Corley

Masters Theses & Specialist Projects

Suggestibility occurs when inaccurate information is incorporated into currently existing memories. The present study examined the effect of forewarning on suggestibility, including the influence of working memory capacity (WMC). The main hypotheses are that forewarnings will reduce suggestibility compared to the control group and that high-WMC will yield lower suggestibility compared to medium- and low-WMC. The final hypothesis is that WMC and forewarning will interact such that low-WMC individuals will benefit more than high-WMC individuals from the forewarning. A sample of 123 college students was recruited. Participants watched a clip of the TV-show 24. WMC was then assessed followed by …

Further Evaluating The Effect Of Behavioral Observability And Overall Impressions On Rater Agreement: A Replication Study, Patrick Sizemore

Masters Theses & Specialist Projects

This replication study sought to analyze the effects of behavioral observability and overall impressions on rater agreement, as recently examined by Roch, Paquin, & Littlejohn (2009) and Scott (2012). Results from the study performed by Roch et al. indicated that raters are more likely to agree when items are either more difficult to rate or less observable. In the replication study conducted by Scott, the results did not support the relationship which Roch et al. found between observability and rater agreement, but did support the relationship previously found between item difficulty and rater agreement. The four objectives of this replication …

The Effects Of Anticipated Feedback Proximity On Performance: Exploring The Moderating Role Of Self-Efficacy And Task Type, Xingya Xu

Masters Theses & Specialist Projects

The present study investigated the effect of anticipated feedback proximity (immediately after completing the task or one week later) on performance and the moderating role of self-efficacy and task types (analytical or creative). I hypothesized that expecting rapid feedback should yield better performance than expecting delayed feedback, for people with high self-efficacy or those who receive analytical tasks. For those who receive creative tasks or have low self-efficacy, expecting rapid feedback may produce negative impact on performance. The results indicated a trend of main effect of anticipated feedback proximity. Specifically, participants performed better when they expected immediate feedback relative to …

Spike Field Coherence (Sfc) For Ripples In Rat Hippocampus, Pranav Singla

Honors Scholar Theses

The aim of this project was to determine coherence between two types of neural recordings which can be obtained from the rat hippocampus: spikes and local field potentials. Extracellular recording makes it possible to determine spiking activity from individual neurons in the vicinity of the recording electrode. Local field potential recording gives a combined activity of many neurons (thousands) at once to determine an overall picture of the coordination of the cells in real time. Here we examine the relationship between these two signals, focusing on place cells which spike at their maximal rate only at certain positions in physical …

Predicting Solitary Confinement, Bryce Young Roby

Doctor of Psychology (PsyD)

Abstract The rates of incarceration in the United States have steadily increased at an average rate of 3.4% per year since 1995, requiring the majority of federal and state institutions to function at or above capacity (Haun, 2007). This influx of adults entering correctional systems has placed increased pressure on prison officials to efficiently and effectively monitor inmate behavior as maintaining the safety and security of the correctional institution is most often the highest priority of correctional administrators (Cullen, Latessa, Burton, & Lombardo, 1993). One security measure commonly implemented to manage inmate violence and disturbances is solitary confinement. This study …

The Effectiveness Of An Evidenced-Based Decision Making Program In Criminal Justice Systems, Tashina Lorraine Keith

Doctor of Psychology (PsyD)

Abstract The National Institute of Corrections selected the Yamhill County Department of Corrections to implement a new evidenced-based decision making program within their criminal justice system. As part of the new program, every individual who was arrested and placed on probation went through a case analysis assessment and had their treatment programs approved by a judge prior to sentencing. In this study 20 randomly selected individuals who received their treatment programming prior to sentencing were matched to 20 randomly selected individuals who received treatment programs post-sentencing. The hypothesis of this study was that those probationers in the pre-sentencing group who …

An Examination Of Psychoeducation And Its Potential Modifying Influence On Alcohol Use Patterns Among Adults Reporting Co-Occurring Posttraumatic Stress Symptoms And Hazardous Alcohol Consumption, Sarah Jo Bujarski

Graduate Theses and Dissertations

Research has suggested that consumption of alcohol in the presence of elevated posttraumatic stress symptom (PTSS) may serve an avoidant function to cope with negative emotions. These coping-related motives for use are theorized to both maintain PTSS and relate to poorer prognoses in treatment for alcohol use disorders (AUDs). Treatments utilizing coping skills training, which typically also involves educating clients about the negative consequences of drinking alcohol to cope, suggest the utility of targeting coping behaviors to reduce alcohol use. These studies, however, have not attempted to isolate the effects of psychoeducation on alcohol-related factors. The current study investigated the …

Humor Types: Replication Using Latent Profile Analysis And Associations With Maladaptive Personality Traits, Joseph Robert Finn

Master's Theses

Martin’s (2003) Humor Styles Questionnaire measures four distinct styles of humor usage. However, examining these humor styles individually fails to account for the combination with which they are used as well as how these combinations may affect the relationship between humor and personality. The present study examined relationships of the humor styles, both individually and in combination, with a broad array of maladaptive personality traits. The incremental validity of accounting for the combinations with which the humor styles are used was examined through the use of hierarchical multiple regressions. Results demonstrated that the humor styles, both individually and in combination, …

Racial Discrimination At The Crosswalk, Tara Goddard, Kimberly Barsamian Kahn, Arlie Adkins

TREC Project Briefs

A look at pedestrian fatality rates in the United States reveals that minorities are disproportionately represented. The Centers for Disease Control and Prevention reported in 2013 that in the first decade of this century, the fatality rates for black and Hispanic men were twice as high as they were for white men. Multi-disciplinary research has shown that racially biased behaviors are evident in many parts of society. Minorities experience differential outcomes in education, employment, health care, and criminal sentencing. Could racially biased treatment exist in transportation as well?

Implicit racial biases are subtle beliefs that individuals may hold beneath the …

Effects Of 17Β-Estradiol On Learning And Memory And Strategy Use During A Hole Board Spatial Navigation Task In Aged Male Rats, Megan Berthiaume

Seton Hall University Dissertations and Theses (ETDs)

Treatment with 17β- estradiol has been shown to ameliorate age related deficits in spatial learning and memory as well as to promote the use of an allocentric strategy during spatial navigation. While the majority of research using 17β- estradiol has been done using females rodents, there have been studies showing an improvement in spatial learning and memory and promoted use of allocentric strategies in spatial navigation in males as well. In males testosterone (T) is metabolized into estradiol by aromatase. As circulating levels of T decline with aging there is less available T to be metabolized into estradiol. The current …

With the advancements of new and emerging technology in the modern cockpit, it is important to understand the effect of these enhancements on performance. Our research seeks to examine both the effect of display type and reliability level on an operator’s performance. The goals of this research are to evaluate and compare the new MATB-II to the original MATB, as well as to further investigate the effect of reliability level in a automated aviation environment.

In the current study, we empirically test the impact of a specified reliability level on performance for a controlled and modernistic automated aviation task. Previous …

The Role Of Attention In Retrieval Practice, Joshua W. Whiffen

Open Access Theses

Dividing attention during encoding is detrimental to learning. In contrast, dividing attention during retrieval appears to have very little effect on recall. However, very few studies have investigated whether dividing attention during initial recall has an impact on subsequent retrieval attempts. ^ Research on retrieval practice has clearly shown that retrieval is an active process that leads to important changes in memory that ultimately enhance long term retention. However, it has yet to be established exactly how retrieval practice derives its benefits. One possibility is that retrieval involves the reinstatement of temporal context, which leads to the updating or encoding …

Ethical Behavior And Ajzen’S Theory Of Planned Behavior Applied To The Decision To Obtain Professional Credentials, Sarajo Paluch

Theses and Dissertations

Currently, the requirement to obtain and maintain professional credentials within the engineering discipline varies among the five military departments within the U.S. Department of Defense (DoD). However, there may be an ethical requirement to do so. The purpose of this research was to investigate ethical theory and behavior theory, and their influence on the decision to obtain and maintain professional credentials. Individual Moral Philosophy (IMP) is one approach describing ethical thought. The Ethics Position Questionnaire (EPQ) measures the two dimensions of IMP: idealism and relativism. The Theory of Planned Behavior (ToPB) is used in research to predict behavior intentions and …
