Experience-Dependent Changes In Nucleus Accumbens Activity Predict Cued Approach Learning: Contribution Of Nmda Receptors, Mercedes Vega Villar
Experience-Dependent Changes In Nucleus Accumbens Activity Predict Cued Approach Learning: Contribution Of Nmda Receptors, Mercedes Vega Villar
Dissertations, Theses, and Capstone Projects
Animals learn associations between environmental cues and the natural rewards they predict (e.g., food, water, sex). As a result, reward-predictive cues come to trigger vigorous reward-seeking responses. Many neurons in the nucleus accumbens (NAc) become excited upon presentation of an already-learned reward-predictive cue. These NAc responses encode the motivational value of the cue and are necessary for the expression of the subsequent approach behavior. However, the precise temporal relationship between the emergence of cue-evoked excitations in the NAc and the acquisition of cued approach behavior remains unknown. In Experiment 1, NAc activity was recorded as rats learned to approach a …
Beyond Exposure: Markers Of English Proficiency In School-Aged French–English Bilinguals, Erin Quirk
Beyond Exposure: Markers Of English Proficiency In School-Aged French–English Bilinguals, Erin Quirk
Dissertations, Theses, and Capstone Projects
Bilingual children show more variation in their language development than monolingual children, a fact that has been linked to their experience with their languages. Bilingual language experience also varies more than monolingual children's, both in terms of how much they hear the language spoken around them (exposure) and how much they speak the language themselves (production). This dissertation investigates the following aspects of the relationship between bilinguals’ language experience and development which are not well-understood: how children’s language production relates to their proficiency in that language, how children’s language exposure relates to receptive versus expressive and lexical versus grammatical skill, …
Mapping The Spatial And Temporal Dynamics Of Visual Percepts Elicited By A Non-Invasive Brain Stimulation Technique, Kelly Webster
Mapping The Spatial And Temporal Dynamics Of Visual Percepts Elicited By A Non-Invasive Brain Stimulation Technique, Kelly Webster
Dissertations, Theses, and Capstone Projects
While many of us rely on vision to interact with and experience the world, for people with damage or disease to the eye or visual cortex, experience through this modality is extremely limited. Brain and retinal stimulation devices show exciting promise for restoring vision, but little is understood about where and when vision percepts can be induced through stimulation. Using a non-invasive brain stimulation technique called transcranial magnetic stimulation (TMS), we characterized the spatial and temporal dynamics of perception induced through brain stimulation. In the first set of experiments, we explore the importance of higher visual and non-visual areas vs. …
Therapist Mentalization And Patient Outcomes In The First Year Of Psychotherapy, Michael Palumbo
Therapist Mentalization And Patient Outcomes In The First Year Of Psychotherapy, Michael Palumbo
Dissertations, Theses, and Capstone Projects
This study examined associations between therapist mentalization and patient outcomes in the first year of psychotherapy. Mentalization is the implicit and explicit consideration of mental states—one’s own as well as others’—and how such states mediate a person’s experiences in the world. It is conceptualized as existing on a scale of increasing complexity. This study sought to extend developmental research that has illustrated the positive influence of a parent’s mentalization on a child’s emotional well-being. Specifically, it was proposed that psychotherapy cases with high levels of therapist mentalization would have better patient outcomes than those with low levels of therapist mentalization. …
Exploring The Relationship Between Perceived Interpersonal Influence And Citizenship Behavior: The Mediating Roles Of Social Identity And Team Member Exchange, Laura Sywulak
Dissertations, Theses, and Capstone Projects
Social or interpersonal influence has been widely studied in both social and organizational psychology, however no research to date has examined how perceptions of one’s ability to influence their coworkers impacts work-related attitudes and behavior. Experimental work in lab settings provides evidence that successfully influencing others consistently leads to increased helping behavior (Bruno, 2013; Bruno et al., 2008; Sywulak, Sommer & Bourgeois, 2013), but the relationship between influence and helping has not been studied in an organizational setting. Further, while several mediating mechanisms have been tested, how perceived influence leads to helping is still unknown. I present a study that …
Asians Applying For Postsecondary Success: Students, Schools, And Socioeconomic Status, Avery M.D. Davis
Asians Applying For Postsecondary Success: Students, Schools, And Socioeconomic Status, Avery M.D. Davis
Dissertations, Theses, and Capstone Projects
Higher education recruitment rates are rapidly declining as schools are stymied by dynamic demographic shifts and a competitive ecosystem. Despite the constant realities of this challenge for tertiary institutions, the complexities of the interplay for demographics, student motivation, parental influences, and school environments during the postsecondary education application process is often overlooked. This thesis analyses how these four domains impact Asian American students within the Education Longitudinal Study (ELS) in terms of the number of postsecondary schools to which they apply? This study examines a sample (N = 662) of the ELS by employing multivariate regression analysis on the number …
Applying A Metacognitive Framework In The Neuropsychological Assessment Of Subjective Cognitive Decline And Mild Cognitive Impairment, Susan Y. Chi
Dissertations, Theses, and Capstone Projects
The characterization of the earliest stages of Alzheimer's disease (AD) is a topic of major research interest because it is critical for early diagnosis and emerging interventions. Metamemory, or knowledge about memory, including awareness of one’s own memory functions, has been investigated in AD especially in relation to how impairment in memory and executive functions contribute to unawareness of cognitive deficits, termed anosognosia. Previous research, however, has not systematically investigated metamemory functioning in older adults with prodromal dementia conditions. Therefore, we investigated metamemory accuracy in cognitively healthy older adults (HC) and those with subjective cognitive decline but intact neuropsychological test …
An Affective Events Theory Analysis Of Conflict Perception Emergence, Michael J. Covell
An Affective Events Theory Analysis Of Conflict Perception Emergence, Michael J. Covell
Dissertations, Theses, and Capstone Projects
Popular conceptualizations of conflict conflate conflict perception with other discrete constructs such as disagreement and emotions. This makes research using those conceptualizations difficult to interpret. I invoke affective events theory to describe how constructs conflated with conflict perception, as well as negative prescriptive expectancy violations (EVs), may collectively serve as antecedents to conflict perception. By reconceptualizing conflict perception as an evaluative judgment and distinguishing between episodic (short-term) and global (long-term) conflict perceptions, my model describes how episodic conflict perceptions cumulatively influence global conflict perceptions over time. Two types of events (disagreements and negative prescriptive EVs) were proposed to predict episodic …
A Grounded Theory Investigation Of The Subjective Responses From Partners In Couples Where Infidelity Has Occurred, Malika Bhowmik
A Grounded Theory Investigation Of The Subjective Responses From Partners In Couples Where Infidelity Has Occurred, Malika Bhowmik
Dissertations, Theses, and Capstone Projects
This qualitative study investigates the subjective responses elicited by partners in long-term committed couples where infidelity has taken place. Each of these couples attended a couple therapy session in the aftermath of their experience of an affair, and the transcriptions of these therapy sessions served as the data set for this investigation. In their seeking of help, most couples articulated a broad, comparable trajectory of the issues; their post-affair understanding of their pre-affair relationship including the state of their pre-affair sex, the origins of the unfaithful partner’s ability to stray from the primary relationship, the impact of the affair on …
Does Clicker Training Lead To Faster Acquisition Of Behavior For Dog Owners?, Brian J. Burton
Does Clicker Training Lead To Faster Acquisition Of Behavior For Dog Owners?, Brian J. Burton
Theses and Dissertations
Clicker training is a method of dog training that has increased in popularity over the past 20 years (Feng et al., 2017). However, while there has been an increased use of clicker training, studies examining the claims that clicker training leads to faster acquisition of new behavior (Skinner, 1951; Pryor, 1999) has only been investigated in a handful of studies with domesticated animals. In addition, all known published studies comparing a clicker-plus-food group to a food-only group have found no significant difference in acquisition of a novel behavior (Dorey & Cox, 2018; Feng et al. 2017), which suggests that a …
Does Resilience Moderate The Impact Of Children’S Experiences Of Racial And Ethnic Discrimination On Internalizing Problems?, Dahlia Abbas
Does Resilience Moderate The Impact Of Children’S Experiences Of Racial And Ethnic Discrimination On Internalizing Problems?, Dahlia Abbas
Dissertations and Theses
This study’s objectives were to investigate how children’s experiences of discrimination impact the severity of their internalizing symptoms, and whether the relation between discrimination and internalizing symptom severity is moderated by resilience. It was predicted that children who had experienced more discrimination would have more severe internalizing symptoms, especially when they have low levels of resilience. Children [N=20; Mean (SD) age= 11.83 (2.50)] receiving low-cost music lessons in northern Manhattan were recruited into a larger study examining how learning music affects cognitive and emotional development. Children were interviewed in-person about experiences of discrimination because of their race/ethnicity using the Perceptions …
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …
Does Overweight/Obesity Moderate The Association Between Adhd And Internalizing Difficulties In Young Adults?, Breanna Badripersaud
Does Overweight/Obesity Moderate The Association Between Adhd And Internalizing Difficulties In Young Adults?, Breanna Badripersaud
Dissertations and Theses
This study’s objective was to investigate if ADHD symptoms and BMI are associated with internalizing impairments of depression, anxiety, stress and lower self-esteem in college students. It was predicted that higher ADHD symptoms would be associated with elevated depression, anxiety, stress, and low self-esteem, especially if BMI fell in the overweight/obese range. Undergraduate students [N= 580; Mean (SD) age= 20.7 (3.10)] from an urban campus completed an online survey comprising self-report measures of demographics, height/weight, attention and hyperactivity/impulsivity (Barkley Deficits Executive Functioning Scale ADHD- Executive Function Index), depression, anxiety, stress (all using the Depression Anxiety and Stress Scale) and self- …
Motivation And Perceived Barriers For Underrepresented Students Interested In Art Therapy, Michael A. Jesson
Motivation And Perceived Barriers For Underrepresented Students Interested In Art Therapy, Michael A. Jesson
Dissertations and Theses
Substantial racial and gender disparities exist in art therapy (AT), with 90% of U.S. art therapists identifying as White and female. This has been identified as a major concern of both practitioners and educators, though little research has been performed. To understand the role of student motivation and barriers to the field, this study recruited 116 undergraduate students academically exposed to AT. Student interest in the field, psychological needs defined by Self-Determination Theory and perceived educational and career barriers were measured. Autonomy, relatedness and competence regarding studies in AT as well as financial barriers were significantly related to interest in …
The Epidemiology Of Somatic Depression And Eating Disorders: The Relationship Between Depressive Subtypes And Symptoms Of Disordered Eating, Anita M. Sicignano
The Epidemiology Of Somatic Depression And Eating Disorders: The Relationship Between Depressive Subtypes And Symptoms Of Disordered Eating, Anita M. Sicignano
Dissertations and Theses
Depression is known to affect females in much greater numbers than males, with about three times as many women having the disorder as men (American Psychiatric Association, 2013). A similar gender disparity can be seen in eating disorders, where up to nine in ten sufferers are female (American Psychiatric Association, 2013). Studies have shown that most of the gender difference in depression occurs as a result of women experiencing a form of depression involving a number of body-centric symptoms, including headaches, weight changes, fatigue, and insomnia, which has been termed “somatic depression” (Silverstein et al., 2013). Some of the symptoms, …
Free-To-Play? An Examination Of Intrinsic Motivation And Gaming Behaviors In U.S. Female Mobile Gamers, Margot Goldblum
Free-To-Play? An Examination Of Intrinsic Motivation And Gaming Behaviors In U.S. Female Mobile Gamers, Margot Goldblum
Dissertations and Theses
The prevalence of U.S. female gamers has skyrocketed in recent years, largely due to the popularity of mobile games; however, this population is underrepresented in academic research. The present study aimed to close this gap in the literature by focusing on the motivations and behaviors of adult female mobile gamers in the U.S. It also aimed to capture changes in gaming motivation and behavior resulting from the onset of the COVID-19 pandemic. An online sample of 354 American women 18 to 77 years of age (M = 36.79, SD = 12.38) were surveyed about their motivations for mobile gaming, …
