Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph
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 …
Semantic Network Activation Contributes To The Relationship Between Mood And Inhibition, James S. Maniscalco
Semantic Network Activation Contributes To The Relationship Between Mood And Inhibition, James S. Maniscalco
Dissertations, Theses, and Capstone Projects
Prior research has identified several relationships between mood and executive functions. Very broadly, these findings generally suggest that positive moods are associated with enhanced cognitive performance, particularly in working memory and learning. However, recent studies note that there are some instances in which negative moods may benefit select executive skills, such as those involved in divided attention and inhibition. In sum, these findings indicate that positive moods favor top-down, heuristic, or relational processing, whereas negative trait moods favor bottom-up, detail-oriented processing. However, a clear mechanism by which these effects occur has yet to be identified.
The most compelling theories that …
Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana
Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana
Dissertations, Theses, and Capstone Projects
Objective: Prior research has shown a bidirectional relationship between breathing, emotions, behavior, and cognitive functions thought to be mediated by the autonomic nervous system (ANS). Studies have shown that deep or diaphragmatic breathing interventions are associated with improved affect and decreased stress levels, but little attention has been paid to the effects of breathing training on cognition. The few studies that have looked at this have shown improved attention, memory, and executive functioning as a result of breathing interventions. While suggestive of positive benefits, these studies used control groups that are either inactive or inappropriate for determining their respective mechanisms …
The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas
The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas
Dissertations, Theses, and Capstone Projects
Strategic overcharging, a practice that some prosecutors readily employ to threaten defendants with excessively severe sentences, undermines the Sixth Amendment right to trial by coercing defendants to plead guilty rather than face penalties disproportionate to their alleged misconduct. Legal scholars and psychologists have long suggested that strategic overcharging may elicit powerful anchoring effects that bias defendants’, but not attorneys’ evaluations, of the plea offer. The current research sought to examine (a) the extent to which mock defendants and legal professionals were susceptible to the anchoring bias, (b) elucidate the mechanism underlying susceptibility to the anchoring effect in plea contexts, and …
Disinhibition And Persistent Maladaptive Behavior, Angela T. West
Disinhibition And Persistent Maladaptive Behavior, Angela T. West
Student Theses
Objective: There is an urgent need to reduce overpopulation in U.S. prisons, which are inundated with individuals needing substance use treatment. Research on both substance use and antisocial behaviors highlight maladaptive beliefs and behaviors, while also implicating disinhibition as an important factor. Disinhibition is a dynamic trait that can be targeted with therapeutic interventions. The current study explored the relationships between neurocognitive disinhibition, substance use, and recidivism among incarcerated men. The study hypothesized that disinhibition would be associated with history of substance use, history of antisocial behavior, and institutional misconduct, as well as predicting recidivism over and above history of …
The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria
The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria
Dissertations, Theses, and Capstone Projects
Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …
Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska
Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska
Dissertations, Theses, and Capstone Projects
Working memory (WM) is the temporary storage of information to accomplish a future goal. The WM delay period is the time after encoding but before retrieval when information is being maintained, typically in the absence of relevant stimuli. Understanding how the brain supports maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM research is how information is stored during this delay period. One …
Rethinking Thinking About Thinking: Against A Pedagogical Imperative To Cultivate Metacognitive Skills, Lauren R. Alpert
Rethinking Thinking About Thinking: Against A Pedagogical Imperative To Cultivate Metacognitive Skills, Lauren R. Alpert
Dissertations, Theses, and Capstone Projects
In summaries of “best practices” for pedagogy, one typically encounters enthusiastic advocacy for metacognition. Some researchers assert that the body of evidence supplied by decades of education studies indicates a clear pedagogical imperative: that if one wants their students to learn well, one must implement teaching practices that cultivate students’ metacognitive skills.
In this dissertation, I counter that education research does not impose such a mandate upon instructors. We lack sufficient and reliable evidence from studies that use the appropriate research design to validate the efficacy of metacognitive skill-building interventions (not just evaluate their relationship to learning outcomes). I argue …
From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood
From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood
Dissertations, Theses, and Capstone Projects
Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …
Thinking And Talking About Kinds, Ye Ji Seoung
Thinking And Talking About Kinds, Ye Ji Seoung
Theses and Dissertations
Three experiments investigated whether definite singular generics (e.g., the dog barks) require that the kind does not contain multiple subkinds. No effect of generic form was found in experiment 1 and 3. However, experiment 2 found people thought there were fewer subkinds when definite singulars referred to the kind.
Representation Of Sex-Linked Properties: Implications For Conceptual Representation And Generics, Olga A. Leus
Representation Of Sex-Linked Properties: Implications For Conceptual Representation And Generics, Olga A. Leus
Theses and Dissertations
Four experiments provide evidence that we represent principled connections between kinds and sex-linked properties such that one type of instance of the kind has a principled connection for the presence of the property and the other type has a principled connection for the absence of that property.

A Conceptual Replication To Investigate The Hostile Priming Effect, Charlotte Basch
A Conceptual Replication To Investigate The Hostile Priming Effect, Charlotte Basch
Theses and Dissertations
The current study attempts a conceptual replication of Srull and Wyer’s 1979 study on hostile priming as part of a large-scale replication. The current study did not find that participants who were exposed to the hostile phrases rated the individual as more hostile as the original study did.

Occupational Depression, Cognitive Performance, And Task Appreciation: A Study Based On Raven’S Advanced Progressive Matrices, Renzo Bianchi, Irvin Sam Schonfeld
Publications and Research
The Occupational Depression Inventory (ODI) was recently developed to assess depressive symptoms that individuals specifically attribute to their work. Research on the criterion validity of the instrument is still in its infancy. In this study, we examined whether the ODI predicted performance on, and appreciation of, a cognitively challenging test. In light of the link established between clinical depression and neuropsychological impairment, and considering that individuals with depressive symptoms are more likely to feel helpless under challenging circumstances, we hypothesized that occupational depression would be associated with poorer cognitive performance and a darkened appreciation of the task undertaken. We relied …
