Voiding The Unwanted Self: An Examination Of Racialized Violence In The United States, Benjamin Stark

Dissertations, Theses, and Capstone Projects

This dissertation is concerned with the role of the psychic defenses projection and projective identification in the processes which lead to racialized violence in the United States. The dissertation posits that projection has been less considered as a primary driver of racialized violence than other psychic processes and should be better integrated into psychological research and literature on racialized violence. The thesis begins with a detailed examination of two instances of racialized violence, the first a macro example of nation vs. nation: the United States’ invasion of Iraq in 2003, before which the United States fantasized Iraq was developing weapons …

The Psychedelic Dasein: Modelling The Effects Of Psilocybin With Heidegger’S Phenomenology, Eamon Robert Stuart Macdougall

Major Papers

This paper argues that the mystical experience induced by psilocybin (understood through the tradition of Heideggerian phenomenology) modulates the attuned understanding of oneself, the world, and how the individual relates to the world. This kind of particular experience is not accessible to the individual through ordinary consciousness, therefore psilocybin may give us access to a new kind of understanding. This understanding may offer a solution to the empirical deficiencies surrounding the short-term and long-term effects of psilocybin, such as how a meagre two to three high doses have yielded unprecedented results in the treatment of tobacco addiction, and in the …

Withdrawal From Voluntary Oral Methamphetamine Reveals Female Specific Susceptibilities To Behavioral Deficits And Neurochemical Perpetuators Of Neurotoxicity And Drug Seeking Behavior, Nicoletta K. Memos

Dissertations, Theses, and Capstone Projects

MA is a potent, highly addictive psychomotor stimulant known to produce neurotoxic effects on the brain leading to neurological impairments^1-6 characterized by neurodegeneration of dopaminergic fibers, cell bodies and pathways, as well as brain regions such as the hippocampus, frontal cortex, and midbrain^1,5.

In MA addiction, women are more vulnerable to the behavioral and cognitive effects of MA compared to men. Adult human literature reveals gender differences in usage patterns and women demonstrate increased vulnerability to the neurotoxic effects and health effects of MA use. Women begin drug use at an earlier age, escalate drug use quicker, …

Diagnostic Featural Detection Or Filler Siphoning: A Red Box Study, Brynn Schuetter

Psychological Science Undergraduate Honors Theses

The current study is a replication and extension of previous research by Colloff and Wixted (2020). In their study, they created a novel identification procedure called the simultaneous showup. They found support for the diagnostic feature detection theory over the filler siphoning theory. The current study was interested in seeing if covert filler siphoning was still occurring in their novel procedure by asking participants how photos of fillers influenced their identification decision. Participants of the study viewed two crime videos and completed an identification task. If they were assigned to the simultaneous showup task, they were asked if and how …

Investigation Of Behavioral Responses Including Visual Side Biases To Social Stimuli In Bottlenose Dolphins (Tursiops Truncatus), Jennifer R. Savoie

Dissertations, Theses, and Capstone Projects

Cetacean field studies have reported consistent population-level side biases for foraging behaviors and this right side feeding bias is arguably the strongest in any species next to handedness in humans. Notably, experimental studies with cetaceans, particularly dolphins, have struggled to find laterality in other behaviors, and some have reported patterns that are inconsistent with those typically found in vertebrates. Side biases related to social processing have been reported in a few observational studies of wild delphinids but have not been successfully evaluated in a controlled experimental context. This dissertation investigated viewing side biases of bottlenose dolphins in two contexts: when …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

Environmental Cues And The Sociospatial Imaginary: An Examination Of Spatial Perception And Meaning-Making In A Gentrifying Neighborhood, Todd Levon Brown

Dissertations, Theses, and Capstone Projects

What could be more ordinary or pedestrian than two people walking down an urban street and talking about what we see and what we make of it? Yet this simple, quotidian act of walking a street—seeing, perceiving and experiencing physical spaces, places and objects—and making meaning of what is encountered, is the basis of my dissertation. It is also my basis for claiming that I have learned a great deal—and much unexpectedly—about how differently different people see and interpret the urban streetscape. What are the various environmental cues that stand out to different individuals? What are the psychosocial imaginaries that …

A Foray Into The Interval Timing Capabilities Of Tufted Capuchin Monkeys (Cebus [Sapajus] Apella), Gryff Griffin

Honors Theses

Time is a critical part of life and timing on the range from milliseconds to minutes has proven to be critical for several behaviors such as foraging and movement. While the exact neurological structures of interval timing are currently undefined, several studies have been completed comparing the interval timing capabilities of humans and nonhuman primates. However, these studies have unanimously utilized members of Macaca, which limits the abilities for researchers to make apt comparisons between humans and all nonhuman primates. This study sought to investigate whether tufted capuchins (Cebus [Sapajus] apella) have the capability to measure time …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

Electronic Theses and Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran

Theses and Dissertations--Psychology

During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …

Exploring Innovation And Behavioral Flexibility In African Lions (Panthera Leo) And Snow Leopards (Panthera Uncia), Victoria L. O'Connor

Theses and Dissertations

Intelligence may have evolved to help animals problem-solve in their physical and/or social environments, which enables them to cope with changes in their environments. Humans can reduce wildlife conflict by understanding how species that face harsh environments assess a situation and alter their behavior. Tests for cognitive behavior aim to formulate clear behavioral criteria for inferring an animal’s mental processes. We designed a custom multi-access puzzle box (MAB) to present a simple and effective behavioral test for exploring innovation in two species, African lions (Panthera leo) and snow leopards (Panthera uncia). Despite being vastly underrepresented in …

Object Permanence In Asian Elephants (Elephas Maximus), Dalia Miller

Theses and Dissertations

This study investigated object permanence in Asian elephants (Elephas maximus) using visible and invisible test paradigms with single and multiple object displacements. Elephants were predicted to succeed, demonstrating a capacity for object permanence and for using vision in a cognitive task. Study outcomes supported these predictions.

The Conundrum Of Causal Reasoning In Elephants, Beri Brown

Master's Theses

Causal reasoning is marked by the ability to mentally reconstruct the missing part of a sequence in order to reproduce an outcome. While research on causal reasoning has been done with children, the results of the studies have been inconsistent. A standardized paradigm for comparative causal reasoning studies does not exist. Nissani (2006) investigated causal reasoning in a tool-use task with elephants and concluded that elephants were not capable of causal reasoning. The current study, a modified replication, yielded results that were not congruent with Nissani’s (2006) manuscript. Additionally, it was very unlikely that the Nissani (2006) study truly looked …

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews

Theses and Dissertations--Psychology

The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

Culture Of Gentleness: A Behavioral Approach, Stevie Parcell

Honors Theses

The purpose of this paper is to explain the fundamentals of an ideological framework for caregivers providing services to people with disabilities called a Culture of Gentleness. The material is traditionally taught within the two-day Working with People training, and the efforts to spread this theory is headed by the Center for Positive Living Supports located in Clinton Township, Michigan. The material is then analyzed through a behavior analytic perspective. Each segment of the initial training will be discussed through both a Culture of Gentleness and behavioral perspective, rooted in Applied Behavior Analysis. Although established in the practice of Positive …

Examining The Effects Of Enclosure Size At Training And At Test In Spatial Reorientation, Zebulon K. Bell

Electronic Theses and Dissertations

Previous research has begun to shed light on the differentiated influence of enclosure size on cue use during reorientation (Sturz, Forloines, & Bodily, 2012). Namely, the question remains of why both feature (i.e., objects or landmarks in the enclosure) and geometric (i.e., shape of the enclosure) cues are differentially affected by enclosure size, and the extent to which local (i.e., wall lengths and corner angles) and global (i.e., principal axis of space) geometric cues are affected by enclosure size. Further, it remains unclear whether training size, testing size, or the relationship between training and testing size influences the use of …

Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens

Electronic Theses and Dissertations

If an organism is trained to approach a location within an enclosure the organism will approach the correct location and it’s geometrically identical location within the environment upon removal of any features. This phenomenon has been turned spatial reorientation, and further studies on how, and to what, organisms reorient have conducted in the last several decades. In the reorientation literature, two theories have surfaced to fill the void left by the rejection of the initial reorientation theory, the Geometric Module theory. I attempt look to discern if the synonym judgement dual task will hinder reorientation in a similar or different …

Title: Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul

Walden Dissertations and Doctoral Studies

The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …

Processing Angry And Happy Faces: The Effect Of Perceptual Load And Familiarity, Peter D. Petronio

Morehead State Theses and Dissertations

A thesis presented to the faculty of the College of Science & Technology at Morehead State University in partial fulfillment of the Requirements for the Degree of Master of Science by Peter D. Petronio in July of 2012.

Perceived Desirability Of Given Names: Identifying A Relationship Between Given Names And Associated Personality Traits, Ellen D. Parks

Undergraduate Theses and Capstone Projects

This study was designed to determine whether participants would have better recall for names with phonetic properties that matched a paired personality trait. In other words, phonetically attractive names paired with positive traits and phonetically unattractive names paired with negative traits should have higher rates of recall than names whose phonetic properties did not match a paired personality trait, such as phonetically attractive names paired with negative traits or phonetically unattractive names paired with positive traits. Given names were deemed to be phonetically attractive or unattractive based on the number of sonorants (soft consonant sounds such as l, m, n, …
