Psychiatric Diagnostic Decision-Making: Investigating The Theory Of The Dual-Process Model, Christopher S. Kleva

Theses and Dissertations

Diagnostic decision-making is an important component of clinical practice; however, there is substantial diagnostic unreliability within mental health diagnoses. The lack of reliability emphasizes the importance of investigating diagnostic decision-making; however, the research to date is limited, primarily relying on a vague definition of decision-making based on the dual-process model. The present study is an exploratory attempt to apply the dual-process model to explain how mental health clinicians (n = 30, 73.3% cisgender female, 96.7% psychologists) arrive at making diagnostic decisions through the use of an interactive interview mechanism. For each participant, we are able to create a figure …

Individual Differences In Structure Learning, Philip Newlin

Theses and Dissertations

Humans have a tendency to impute structure spontaneously even in simple learning tasks, however the way they approach structure learning can vary drastically. The present study sought to determine why individuals learn structure differently. One hypothesized explanation for differences in structure learning is individual differences in cognitive control. Cognitive control allows individuals to maintain representations of a task and may interact with reinforcement learning systems. It was expected that individual differences in propensity to apply cognitive control, which shares component processes with hierarchical reinforcement learning, may explain how individuals learn structure differently in a simple structure learning task. Results showed …

Contextual Creativity: The Role Of Ambiguity In Creative Cognition, Sarah K. C. Dygert

Theses and Dissertations

This body of work is composed of three individual papers that each seek to explain individual differences in creative cognition. Paper 1 used structural equation modeling to examine the ways in which creative problem solving and creative idea generation relate or differ. Results from Paper 1 demonstrate that divergent thinking and creative problem solving are best represented as a bifactor model, bearing distinct domain-specific factors, as well as a shared domain-general factor. Though working memory and fluency of memory retrieval explained significant portions of the domain-specific constructs, they only explained ~2% of variance in the domain-general factor. Paper 2 explores …

The Role Of Knowledge Representations In Rule Transfer On A Novel Problem-Solving Task, Megan J. Raden

Theses and Dissertations

Although the independent roles of working memory capacity (WMC) and knowledge in problem solving have been thoroughly researched, there is significantly less work that has explored how WMC and knowledge interact during problem solving. The present study investigated how the quality of knowledge representations contribute to rule transfer in a problem-solving context and how WMC might contribute to the subsequent failure or success in transferring the relevant information. Participants were trained on individual figural analogies rules and then asked to rate how similar they thought the rules were to determine how stimulispecific or abstract their rule representations were. Their rule …

The Effect Of Strategy Instruction And Spatial Ability On Spatial Problem Solving, Nia Scarboro

Theses and Dissertations

High spatial skills tend to be a strong indicator for predicting STEM success. There are varying abilities when it comes to spatial skills, despite that spatial skills are adaptable and can develop with proper training. The aim of this experiment was to investigate the role of strategy instruction on spatial thinking performance. More specifically whether or not a response elimination strategy (count the number of folds and multiply by two) or a visualization strategy (imagining unfolding the paper) would be more beneficial in terms of improving Paper folding task score. Students participating in this experiment were undergraduate students from St. …

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 …

Discrete Processing In Visual Perception, Marshall L. Green

Theses and Dissertations

Two very different classes of theoretical models have been proposed to explain visual perception. One class of models assume that there is a point at which we become consciously aware of a stimulus, known as a threshold. This threshold is the foundation of discrete process models all of which describe an all-or-none transition between the mental state of perceiving a stimulus and the state of not perceiving a stimulus. In contrast, the other class of models assume that mental states change continuously. These continuous models are founded in signal detection theory and the more contemporary models in Bayesian inference frameworks. …

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

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.

Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs

Theses and Dissertations

The current literature suggests that subjective time duration could be the common currency used for task choice. However, few studies have been conducted that use non-physical tasks for their task choice options. Thus, the purpose of the current study was to examine if subjective time duration is the common currency for task choice regardless of task type. Participants first provided their subjective time estimates for each of the perceptual-motor and cognitive tasks that have been a priori determined to be at the medium difficulty level. Two cognitive tasks (item generation and math problem task) and one perceptual-motor task with a …

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.

Effect Of Task-Irrelevant Emotional Faces On Attention To A Letter Search Task At High And Low Perceptual Loads, Nina Plotnikov

Theses and Dissertations

The attentional processing of emotional faces has interested researchers over the past thirty years. However, differing methodology has led to inconsistent findings. It has been suggested that using emotional faces as task-irrelevant distractors and varying perceptual load of the primary task can create an experimental framework that will allow attentional capture by emotional face processing to be better identified and differentiated from other processes. Furthermore, the effects of time on-task on attentional processing of emotional faces are currently not well understood, in part because traditional statistical analyses, such as the ANOVA, are insufficient for finding longitudinal trends in the data. …

Third Culture Kids - Playing To Heal, Amna Sana

Theses and Dissertations

With increased globalization and a large expat population, Qatar is home to increasing numbers of Third Culture Kids (TCKs). TCKs are children who live in a country where their parents are non-native, children who grow up between cultures. Young TCKs, especially children between the ages of three and seven, do not possess the skills to adequately vocalize their feelings, but fortunately, play therapy allows them to articulate problems and feelings on their own terms. This thesis addresses the emotional hurdles facing TCKs, using concepts derived from play therapy and offering a series of interactive objects designed to reflect emotional expression …

Are Giant Pandas (Ailuropoda Melanoleuca) Averse To Inequity?, Miranda R. Trapani

Theses and Dissertations

Inequity aversion, a negative response to situations of unequal reward distribution, is a cognitive trait usually seen in social species. This capacity is thought to regulate cooperative relationships in intelligent, cognitively flexible animals. Giant pandas are a unique case in that wild populations are characterized as nonsocial, however captive populations are socially housed until sexual maturity. This allows for the study of a nonsocial species in a social context and thus the assessment of socio-cognitive flexibility across evolutionarily distant taxa. Here, we assessed whether the giant panda (Ailuropoda melanoleuca) displays inequity aversion by testing ten juveniles living at …

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith

Theses and Dissertations

This study examined contrafreeloading—choosing a physical task to access food over free food—in two Grey parrots (Psittacus erithacus). Both birds contrafreeloaded for food of equal or higher value, but differed in which contrafreeloading task they preferred. Differences between the parrots are considered as individual preferences for self-reinforcing tasks.

Testing Reliability Of Biophilic Design Matrix Within Urban Residential Playrooms, Ellen Marte

Theses and Dissertations

Biophilic interior design in urban playrooms has been greatly understudied. We measured inter-rater reliability of the Biophilic Interior Design Matrix (BID-M) and matrix items by quantitatively coding images of 45 New York City residential playrooms. Findings suggest that the BID-M needs to be modified to better assess urban playrooms.

Talking And Thinking About Animal And Artifact Kinds Via Different Types Of Generics, Lyan-Joy M. Lugay

Theses and Dissertations

Generic statements are expressions that talk about kinds or categories and there are several forms. Through the use of surveys, this study examined the way native English speakers talk and think about novel animal kinds and artifacts using two forms: the definite singular form and the bare plural form.

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 Role Of Mirror Neurons In Relational Dysfunction In Posttraumatic Stress Disorder, Andrew Walker

Theses and Dissertations

American military involvement in Iraq and Afghanistan has created a new generation of veterans suffering from posttraumatic stress disorder (PTSD). It has repeatedly been noted that these returning veterans have a particularly difficult time reconnecting with family and friends. Because of these findings, the impact of multiple deployments and prolonged combat exposure is shifting from the individual veteran to its effects on their ability to reestablish intimate relationships after the completion of their service.

Over the last 20 years, numerous studies have directly observed the firing of the same neurons of non-human primates while seeing a member of their species …

Visual Illusion Susceptibility In Dogs Using The Ebbinghaus-Titchener Illusion In A Spontaneous Choice Task, Nicolette Becker

Theses and Dissertations

In recent years, dogs have been a popular test subject when studying visual illusion susceptibility. Multiple studies have investigated whether animals perceive illusions as humans do, but few studies have evaluated dogs’ perception of illusory stimuli. In this thesis, we studied if dogs are visually susceptible to the Ebbinghaus-Titchener illusion when presented in a spontaneous choice task. Subjects were presented two visual images on a board, which had bologna pieces embedded in the stimuli. In control trials, two different sized bologna pieces were placed in the center of the images. In these control conditions, dogs were expected to choose the …

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 …

Behavioral Hypervigilance In A Normative Population, Karly Weinreb

Theses and Dissertations

Hypervigilance is conceptualized as a symptom of trauma-related disorders, however it can also occur in a normative population. To distinguish normative hypervigilance from trauma-related hypervigilance, 372 participants (123 trauma-exposed and 249 non-trauma-exposed) completed a questionnaire assessing hypervigilance in contexts. Trauma-exposed participants reported greater levels of hypervigilance in 3 contexts.

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.

Visual And Verbal Serial List Learning In Patients With Statistically-Determined Mild Cognitive Impairment, Victor J. Wasserman

Theses and Dissertations

Objective: To compare verbal versus visual serial list learning test performance in mild cognitive impairment (MCI) and assess relationships between serial list learning and hippocampal volume. Methods: Patients were diagnosed with non-MCI, amnestic MCI (aMCI), and combined mixed/dysexecutive MCI (mixed/dysMCI). Outcome measures included immediate/delay free recall, and delay recognition performance from the 12-word Philadelphia Verbal Learning Test (PrVLT) and the Brief Visuospatial Memory Test-Revised (BVMT-R). Lateral hippocampal volumes were obtained. Results: Non-MCI patients scored better than other groups on P(r)VLT immediate/delay free recall. aMCI patients scored lower than other groups on P(r)VLT delay recognition. Non-MCI patients were …

Differences In Spatial Visualization Ability And Vividness Of Spatial Imagery Between People With And Without Aphantasia, Anita Crowder

Theses and Dissertations

Mathematics education researchers have examined the relationship between visualization and mathematics for decades (e.g., Arcavi, 2003; Bishop, 1991; Duval, 1999; Fennema & Tartre, 1985; Presmeg, 1986). Studies have linked spatial visualization ability, such as measured in mental rotation tasks, directly to mathematics self-efficacy (Pajares & Kranzler, 1995; Weckbacher & Okamoto, 2014), which in turn influences mathematics achievement (Casey, Nuttall, & Pezaris, 1997). With the important role that spatial visualization plays in learning mathematics, the recent identification of congenital aphantasia (Zeman, Dewar, & Della Sala, 2015), which is the lack of mental imagery ability, has raised new questions for mathematics education …

Effects Of Mood On Processing In Event-Based Prospective Memory, Rachel A. Workman

Theses and Dissertations

Different moods seem to elicit different processing styles (Hunt & McDaniel, 1993, Storbeck & Clore, 2005) and mood has been shown to affect retrospective memory in many ways. The current research investigated how induced mood affects event-based prospective memory (PM). The current study examined mood effects on focal and non-focal PM retrieval. Participants were induced into either a depressive or elated state using Velten statements directly prior to retrieval of the PM task. A main effect of task type was found, such that those in the focal condition completed the task quicker and more accurately than those in the non-focal …

Multilingualism And Ego Depletion In Interference Task Performance – Are Multilingual Brains More Intelligent Than Monolingual Brains?, Dorota B. Botwina

Theses and Dissertations

Research linking multilingualism with better executive control has produced inconsistent findings. Since definitive empirical evidence is not available, this study seeks to explore whether these advantages really exist. The Flanker Task followed an ego depletion task that was introduced to participants who were monolingual, bilingual and trilingual.

Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell

Theses and Dissertations

Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G₂ = 78.10, p < 0.001).
