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,

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,

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 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?,

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 …

Western Kentucky University
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 …

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 …
