Perception Of Promotability Among Employees In Nonprofit Health And Social Impact Services, Victoria Leann Rodino

Walden Dissertations and Doctoral Studies

Many human resource departments are developing and improving their talent management systems to identify and develop employee talent within the organization. However, nonprofit organizations face unique challenges including under-developed human resource structures and limited resources or funds. As a result, many nonprofit organizations are unable to effectively communicate their promotability processes, resulting in negative employee behaviors including lack of motivation, decreased engagement, and enhanced turnover intention. The purpose of this study was to explore and understand the employee perception of promotability within the nonprofit sector. Social exchange and social cognitive theories were used to explore the perception of promotability among …

A Qualitative Study Exploring The Impact Of Anxiety On The Sibling Relationship, Maria Hays

PCOM Psychology Dissertations

Sibling relationships are one of the most critical elements of interpersonal functioning for children. The sibling relationship has been found to be an important foundation for the development of relationships in general, as siblings spend more time together than with anyone else. Mental health of a sibling has been found to impact the quality of the relationship; however, although anxiety is one of the most prevalent mental health disorders in children, there is a dearth of literature on its impact on the sibling relationship. The purpose of this study was to determine the perceptions siblings have about their experiences of …

Autism Spectrum Disorder (ASD), is a neurodevelopmental disorder with a deficit in social interaction characteristics, relationships, and stereotyped behaviors. This study examined Iranian parents’ perceptions of physical activity for their children with ASD during the COVID-19 pandemic.

Methods: In this study, an explanatory qualitative methodology was used and data were collected via semi-structured phone interviews. The samples included 40 Iranian parents (aged …

Police Perceptions And Parenting Styles Among Black Parents Of Miami-Dade County, Amber E. Roach

Masters Theses

A person’s perception of something or someone does not develop without external factors affecting the individual. Experiences and lessons people have learned from a young age have molded their perception of the world. One of those lessons is what is considered correct and what is not. In the Black American community, this is accompanied by the “talk”. This “talk” is shaped by past experiences with the police towards minority groups, specifically, Black Americans. This paper discusses how parenting styles, race, and authority intersect. The purpose of this paper is to examine the beginnings of one’s life, the lessons they are …

Musical Instrument Familiarity Affects Statistical Learning Of Tone Sequences., Stephen C Van Hedger, Ingrid Johnsrude, Laura J Batterink

Brain and Mind Institute Researchers' Publications

Most listeners have an implicit understanding of the rules that govern how music unfolds over time. This knowledge is acquired in part through statistical learning, a robust learning mechanism that allows individuals to extract regularities from the environment. However, it is presently unclear how this prior musical knowledge might facilitate or interfere with the learning of novel tone sequences that do not conform to familiar musical rules. In the present experiment, participants listened to novel, statistically structured tone sequences composed of pitch intervals not typically found in Western music. Between participants, the tone sequences either had the timbre of artificial, …

Odors In Cognitive Research: A Commentary On 'Scented Colours' And An Evaluation Study On Odor Quality, With The Example Of Human Wayfinding, Kai Hamburger, Denise Herold

Baltic International Yearbook of Cognition, Logic and Communication

In his target article on “Scented Colours”, Charles Spence highlights the importance of crossmodal connections by focusing on the interaction between odors and colors. In this commentary and our presentation of own empirical work in this research context, we want to reach out further by emphasizing this importance not only on a perceptual and representational level, but also highlight it as an example for spatial cognition research. We provide an evaluation study on emotional effects of odors that could be used in future interdisciplinary research. While the meaning of odors in spatial wayfinding is, thus far, not well investigated, we …

Memoir Dataset: Quantifying Image Memorability In Adolescents, Gal Almog, Yalda Mohsenzadeh

Undergraduate Student Research Internships Conference

Every day, humans observe and interact with hundreds of images and scenes; whether it be on a cellphone, on television, or in print. Yet a vast majority of these images are forgotten, some immediately and some after variable lengths of time. Memorability is indeed a property intrinsic to all images that can be extracted, as well as predicted. While memory itself is a process that occurs in the brain of an individual, the concept of memorability is an intrinsic, continuous property of a stimulus that can be both measured and manipulated. We selected images from the MemCat data set that …

Driving Habits, Cognition, And Health-Related Quality Of Life In Middle-Aged And Older Adults With Hiv, Josiah J. Robinson, Tess Walker, Cierra Hopkins, Brittany Bradley, Peggy Mckie, Jennifer S. Frank, Caitlin N. Pope, Pariya L. Fazeli, David E. Vance

Graduate Center for Gerontology Faculty Publications

Cognitive impairment is known to increase with aging in people living with HIV (PLWH). Impairment in cognitive domains required for safe driving may put PLWH at risk for poor driving outcomes, decreased mobility, and health-related quality of life (HRQoL). This study described the driving behaviors of middle-aged and older PLWH and examined correlations between driving behaviors and cognitive functioning (Aim 1), and driving behaviors and HRQoL domains (Aim 2). A sample of 260 PLWH ages 40 and older completed a comprehensive assessment including a battery of cognitive tests, an HRQoL measure, and a measure of self-reported driving habits. Associations between …

How Well Do You Know Your Reach?, Tyler Surber

Dissertations

How does the relationship between an actor’s body proportions (eye-, shoulder-, and arm length) and environmental properties (object distance) affect the perception of whether an object is within reach? Experiment 1 demonstrated that participants are more accurate at judging their own eye height than shoulder height. Experiment 2 revealed that participants can accurately perceive the angular direction to a target object’s location. Interestingly, their pointing errors were significantly smaller when measured from the shoulder as a reference point than from the eye. In Experiment 3 we verified this finding using a functionally meaningful affordance task of reaching to a target …

Moral Circles And Mind Perception Shift Perceptions Of Effective Altruism, Kyle Fiore Law

Legacy Theses & Dissertations (2009 - 2024)

Across a re-analysis of an existing dataset (Study 1; N = 96) and a higher-powered new study (Study 2; N = 300), we reveal that moral valuation of environmentalism over humanitarianism predicts less favorable moral judgments of effective altruism (i.e., welfare-maximizing socially distant altruism directed at humans) that is performed at the exclusion of helping animals in need. Furthermore, this relationship is explained by tendencies in mind perception to dehumanize outgroup members and stigmatized humans, rather than tendencies to anthropomorphize animals (Study 2). These findings reveal that granular versus aggregate individual differences in moral circles and mind perception may be …

More Evidence That Magnitude Interference In Temporal Reproduction Results From Memory, Not Clock, Interference, Steven A. Masi

Seton Hall University Dissertations and Theses (ETDs)

Past research has found that errors made when acting on magnitude information is influenced by irrelevant magnitude information that is simultaneously present in the environment. This study investigated the processing stage during which the interference occurs. Each participant completed 80 test trials in stimulus (encoding stimulus) appeared on the computer screen for one of four lengths of time and then disappeared. After which, participants held down the computer spacebar for either the full or half the time that the encoding stimulus was on the screen. In both conditions, a second stimulus (reproduction stimulus) was displayed as the participants held down …

Examining Perceptions Of Anorexia Nervosa, Polly Mcgonigle

Undergraduate Honors Theses

Anorexia nervosa (AN) is an eating disorder characterized by a restriction of energy intake, an intense fear of gaining weight, and often distorted body image. AN has the second highest mortality rate of all psychiatric disorders, due to high suicide rates and medical complications associated with malnutrition. An estimated 10% of those who have AN die because of the disorder (Insel, 2012). Interacting factors—genetic, biological, environmental, and psychosocial—contribute to the etiology and maintenance of AN. However, outside of research settings, AN is misunderstood as having primarily environmental roots (Salafia, et. al). Blame is placed on societal expectations and the disorder …

The Influence Of Mental Fatigue On Sessional Ratings Of Perceived Exertion In Elite Open And Closed Skill Sports Athletes, Joseph O. C. Coyne, Aaron J. Coutts, Robert U. Newton, G. Gregory Haff

Research outputs 2014 to 2021

ABSTRACT: Coyne, JOC, Coutts, AJ, Newton, RU, and Haff, GG. The influence of mental fatigue on sessional ratings of perceived exertion in elite open and closed skill sports athletes. J Strength Cond Res 35(4): 963-969, 2021-The main purpose of this investigation was to examine influence of mental fatigue on sessional ratings of perceived exertion (sRPE) over a training week in elite athletes in open skill (OS, i.e., more unpredictable and externally paced sports) and closed skill (CS, i.e., more predictable and internally paced) sports. Visual analogue scales for mental fatigue, sRPE (CR-10 scale), and training duration were collected from an …

Searching: Waves, Spencer Molnar

Theses and Dissertations

This supportive statement examines a philosophical conception of the self and how it can be identified through experience, consciousness, and perception by focusing on a human inclination to rationalize, or concretize, that which is everchanging. The methods of exploring this concept were achieved by examining the formal structure of composition and materials through the process of visual art. By pushing against historical traditions of creating spatial illusions in visual art, we can conclude that the legibility of an artwork is equally dependent on the experiential world as it is the social construction of image making. The question that is left …

Intelligibility Benefit For Familiar Voices Does Not Depend On Better Discrimination Of Fundamental Frequency Or Vocal Tract Length, Emma Holmes, Ingrid Johnsrude

Brain and Mind Institute Researchers' Publications

Speech is more intelligible when it is spoken by familiar than unfamiliar people. Two cues to voice identity are glottal pulse rate (GPR) and vocal tract length (VTL): perhaps these features are more accurately represented for familiar voices in a listener’s brain. If so, listeners should be able to discriminate smaller manipulations to perceptual correlates of these vocal parameters for familiar than unfamiliar voices. We recruited pairs of friends who had known each other for 0.5–22.5 years. We measured thresholds for discriminating pitch (correlate of GPR) and formant spacing (correlate of VTL; ‘VTL-timbre’) for voices that were familiar (friends) and …

The Effect Of Test Difficulty On Perceived Memory Performance, Phoebe S. Bean

Graduate Student Theses, Dissertations, & Professional Papers

Neuropsychological testing is a critical element of the assessment and treatment of a host of neurological disorders, such as Alzheimer’s Disease, stroke, and traumatic brain injury. Certain non-neurological variables may also affect an individual’s test performance. Such secondary factors may include current psychiatric issues, chronic pain, sleep, and the effort put forth during testing. Little is known, however, about the effect the testing process itself has on people’s actual and perceived cognitive abilities. For example, the process of undergoing memory testing may, through a variety of mechanisms, influence memory performance and impact the person such that their view of their …

Stress Perceptions And Verbal Commands For Law Enforcement In High-Stress Situations, John Kenneth Gibson

Walden Dissertations and Doctoral Studies

Acute stress can have a negative effect on the physiology and cognitive performance of peace officers when they are engaged in high-stress situations. This could lead to injury or loss of life if a mistaken perception occurs or incorrect decision is made by the officer or suspect. The purpose of this qualitative phenomenological study was to explore the perceptions of stress for peace officers who issue verbal commands to an aggressive role-playing suspect in a use-of-force scenario. The theoretical framework was Lazarus and Folkman's transactional theory of stress and coping. Data were collected from observations, field notes, and semi-structured interviews …

Effects Of Spatial Language Cues On Attention And The Perception Of Ambiguous Images, Aaron Foster

Cal Poly Humboldt theses and projects

It’s a bird! It’s a plane! It’s superman!? Sometimes there are things in our world that are ambiguous. An ambiguous object, for the purposes of this thesis is any object that has more than one interpretation to it. The brain is designed to “fill in the blanks” and make sense of the world. Thus it will use anything available, like language, to help in resolving the ambiguity. Language can change how we perceive information in the world (Dils & Boroditsky, 2010) and where we direct our attention (Ostarek & Vigliocco, 2017; Estes et. al. 2008; Estes, Verges, Adelman, 2015). Language …

Investigating How The Modularity Of Visuospatial Attention Shapes Conscious Perception Using Type I And Type Ii Signal Detection Theory, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Attention abilities rest on the coordinated interplay of multiple components. One consequence to this multifaceted account is that selection processes likely intersect with perception at various junctures. Drawing from this overarching view, the current research examines how different forms of visuospatial attention influence various aspects of conscious perception, including signal detection, signal discrimination, visual awareness, and metacognition. In this effort, we combined a double spatial cueing approach, where stimulus- and goal-driven orienting were concurrently engaged via separate cues, with Type I and Type II signal detection theoretic frameworks through five experiments. Consistent with the modular view of visuospatial attention, our …

The Experience Of Conflicting Identities Amongst African American Law Enforcement Officers, Jeremy R. Jones

Walden Dissertations and Doctoral Studies

Law enforcement’s unjust treatment of African Americans is a worldwide concern but impacts the African American community in different ways, particularly African American law enforcement officers who are placed in conflicting positions. They aspire to see change and more conforming police treatment, compared to other racial populations, but work for the same organization that exhibits the biased treatment they desire to have abolished. The purpose of this qualitative research study was to explore African American law enforcement officers’ experiences of conflicting identities. The theoretical foundation was based on Turner’s theory of self-categorization (SCT). The key research questions addressed African American …

Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at …

Is Executive Function The Universal Acid?, Stephen J. Morse

All Faculty Scholarship

This essay responds to Hirstein, Sifferd and Fagan’s book, Responsible Brains (MIT Press, 2018), which claims that executive function is the guiding mechanism that supports both responsible agency and the necessity for some excuses. In contrast, I suggest that executive function is not the universal acid and the neuroscience at present contributes almost nothing to the necessary psychological level of explanation and analysis. To the extent neuroscience can be useful, it is virtually entirely dependent on well-validated psychology to correlate with the neuroscientific variables under investigation. The essay considers what executive function is and what the neuroscience adds to our …

S3e6: How Do Face Masks Affect First Impressions?, Ron Lisnet, Mollie Ruben

The Maine Question

There’s an adage that people don’t get a second chance to make a first impression. Mollie Ruben, assistant professor of psychology, examines how face masks affect people’s first impressions of others during the COVID-19 outbreak. Do people appear more or less smart to others, depending on whether they’re wearing or not wearing a mask? More or less friendly? Learn about this research project conducted by Ruben, who directs the Emotion, Pain, and Interpersonal Communication (EPIC) Lab at the University of Maine.

Young Men’S Perceptions Of Teenage Pregnancy, Oluwatoyin Adewole, Oluwaseun M. Otubanjo

The Qualitative Report

The purpose of the qualitative study was to understand the perceptions and experiences of young men who lived in a county of Texas regarding teenage pregnancy. Face-to-face audio-taped interviews were conducted with 20 young men between ages 18 and 21. Five major themes and one subtheme were uncovered from the interview: unplanned pregnancy/attitude to unprotected sex, being a father at an early age, wanting sex education in the school curriculum, advice for other young men, and desiring parent’s role in sex education. The sub-theme was early childhood education to start at home. The findings of this study demonstrate that young …

Development And Validation Of A Multidimensional Scale For Measuring Public Confidence In The Criminal Justice System, Jimin Pyo

Dissertations, Theses, and Capstone Projects

Two studies were conducted with an aim of developing multidimensional measures of public confidence that are conceptually integrated, psychometrically sound, and useful in predicting individuals’ law related behaviors. Study 1 involves two-phased construction of scale in which a preliminary inventory was generated (Phase 1) and then finalized after evaluating psychometric properties based on 304 US adults recruited through Amazon’s Mechanical Turk (MTurk) (Phase 2). As a result, six multidimensional scales were constructed respectively for measuring efficiency-, finality-, fairness-, strictness-, accuracy-, and transparency-oriented confidence. Despite more complexity of factor structures than originally expected, results of psychometric evaluation six scales of confidence …

Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen O'Donnell

Electronic Theses, Projects, and Dissertations

As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …

Let's Get Physical: The Dual-Task Costs Of Multiple Motor Responses, Taylor Nicole Hutson

Masters Theses and Doctoral Dissertations

Dual-task costs occur when attention is divided among two or more concurrent tasks. Most dual-task studies involve paradigms where participants complete two, concurrent cognitive tasks; in these studies, performance on one or both tasks are slower and/or less accurate. The goal of this study was to examine whether dual-task costs would exist when participants completed a cognitive task while walking and whether those costs would be greater when the cognitive task required a motor-based response or when the task was more difficult. Twenty-two college students completed four blocks of a visual search task while walking. The difficult and the manual …

The Effects Of Self-Regulation Depletion And Race On The Willingness To Interact With Individuals With Mental Illness, Kenocha K. Epperson

Electronic Theses and Dissertations

Although the discrimination that Black individuals encounter is unique, it is similar in some ways to the discrimination experienced by individuals with mental illness (Corrigan & Wassel, 2008; Follmer & Jones, 2018; Jackson & Stewart, 2003). Research has found that these kinds of stigma can be overridden (Baumeister et al., 1998), but doing so requires self-regulation, which can be depleted (Gailliot et al., 2007). Because stigma exists against both Black individuals and those with mental illness, and because self-regulation is necessary to override those stigmas, the purpose of this project was to examine the relationships to which Black participants would …

Perception Of County Extension Agents’ Organizational Fit After Participating In The Mentoring Component Of The Cooperative Extension Service Onboarding Program, Angela Blacklaw-Freel

Graduate Theses and Dissertations

The purpose of this study is to determine the perception employees of the Arkansas Cooperative Extension Service (CES) after participating in a mentoring program. The CES implemented an onboarding program in 2010 which included a yearlong mentoring component for county extension agents because they were resigning at an alarming rate. The study aimed to illuminate if the mentoring program increased the county extension agents’ perception of fit after completing the program by determining if they felt they possessed characteristics that were compatible with the organization.

This study was founded on the mentees’ viewpoints of their perceptions of person-organization (PO) fit, …

Perceptual Characterization: On Perceptual Learning And Perspectival Sedimentation, Anthony Holdier

Graduate Theses and Dissertations

In her analysis of perspectival effects on perception, Susanna Siegel has argued that perceptual experience is directly rationally assessable and can thereby justify perceptual beliefs, save for in cases of epistemic downgrade or perceptual hijacking; I contend that the recalcitrance of known illusions poses an insurmountable problem for Siegel’s thesis. In its place, I argue that a model of perceptual learning informed by the dual-aspect framework of base-level cognitive architecture proposed by Elisabeth Camp successfully answers the questions motivating Siegel’s project in a manner that avoids such issues.
