Hand Use Predicts The Structure Of Representations In Sensorimotor Cortex., Naveed Ejaz, Masashi Hamada, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

Fine finger movements are controlled by the population activity of neurons in the hand area of primary motor cortex. Experiments using microstimulation and single-neuron electrophysiology suggest that this area represents coordinated multi-joint, rather than single-finger movements. However, the principle by which these representations are organized remains unclear. We analyzed activity patterns during individuated finger movements using functional magnetic resonance imaging (fMRI). Although the spatial layout of finger-specific activity patterns was variable across participants, the relative similarity between any pair of activity patterns was well preserved. This invariant organization was better explained by the correlation structure of everyday hand movements than …

Changes In Visual And Sensory-Motor Resting-State Functional Connectivity Support Motor Learning By Observing., Heather R Mcgregor, Paul L Gribble

Brain and Mind Institute Researchers' Publications

Motor learning occurs not only through direct first-hand experience but also through observation (Mattar AA, Gribble PL. Neuron 46: 153-160, 2005). When observing the actions of others, we activate many of the same brain regions involved in performing those actions ourselves (Malfait N, Valyear KF, Culham JC, Anton JL, Brown LE, Gribble PL. J Cogn Neurosci 22: 1493-1503, 2010). Links between neural systems for vision and action have been reported in neurophysiological (Strafella AP, Paus T. Neuroreport 11: 2289-2292, 2000; Watkins KE, Strafella AP, Paus T. Neuropsychologia 41: 989-994, 2003), brain imaging (Buccino G, Binkofski F, Fink GR, Fadiga L, …

Individual Adaptability As A Predictor Of Job Performance, Stephanie L. Murphy

Doctoral Dissertations

In the new global economy, organizations frequently have to adjust to meet challenging demands of customers, competitors, or regulatory agencies. These adjustments at the organizational level often cascade down to employees, and they may face changes in their job responsibilities and how work is performed. I-ADAPT theory suggests that individual adaptability (IA) is an individual difference variable that includes both personality and cognitive aspects and has both trait- and state-like properties. As a result, IA may be an acceptable alternative for traditional, stable selection tests for operating within unstable environments. The present paper examined the relationship of individual adaptability, cognitive …

The Relationship Between Sleep And Nutrition In Message Framing Among College Students, Abbey G. White

Doctoral Dissertations

The college years are often depicted as a time of immense change, specifically in relation to college students' level of nutrition and sleep quality. However, these health concerns not only impact college students' health but also their academic performance, mood, and as a result their future. The primary purpose of this study was to determine whether technologically enhanced health messages are more effective than the traditional text format for creating healthy behavioral changes amongst college students. Secondly, the study provides the opportunity to examine previous research involving message framing, specifically, regulatory focus theory and self-efficacy, in order to provide further …

Application Of Item Response Theory To Measures Of Verbal Learning, Indrani K. Thiruselvam

Dissertations (1934 -)

This study utilized item response theory (IRT) methods to investigate if item parameters of select trials in the California Verbal Learning Test-Second Edition (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) and the Logical Memory subtests of the Wechsler Memory Scales – Fourth Edition (WMS-IV; Wechsler, 2009) vary as a function of the serial position effect. In addition, this study compared the effectiveness of CVLT-II and LM in quantifying verbal memory functioning, and determined if a weighted scoring approach improves the quantification of verbal memory. Archival data from 755 individuals (516 college students, 239 patients at a neuropsychology clinic) were utilized …

The Effects Of Specific Mental Illness Stigma Beliefs On Treatment Seeking Attitudes, Henry Arthur Boeh

Dissertations (1934 -)

Despite significant gains in the research base and effectiveness of psychotherapy, only thirty to forty percent of individuals experiencing mental illness symptoms seek treatment. A large barrier preventing many individuals from seeking psychotherapy is the stigma that surrounds mental illness. This study reviews the current state of mental illness stigma literature and presents a new Treatment Seeking Barriers Model (TSBM) that attempts to better explain the connection between stigma and treatment seeking. The goal of the current study was to isolate and manipulate responsibility or immutability beliefs related to depression in order to evaluate their relationship with treatment seeking stigma. …

Objectively Measuring The Effects Of Sleep On Reading Comprehension And Sustained Selective Attention, Jennifer L. Thibodeaux

Doctoral Dissertations

The overall performance of a university is measured by retention rates of students. Because individuals who achieve lower grade point averages are at a higher risk of failing or dropping out of college, the academic performance of undergraduates should be the target of concern to maintain good retention rates. Academic performance, which is associated with attention and reading comprehension abilities, is affected by the sleep behavior of students. In regards to college students and sleep, research has indicated that college students demonstrate habitually poor sleep habits. Poor sleep habits have been linked to impaired attention and concentration abilities, but the …

Cultural Context's Influence On The Relationships Between Leadership Personality And Subordinate Perceptions, Victoria J. Smoak

Doctoral Dissertations

Fascination with leadership and the pursuit of its understanding have been common across disciplines throughout history (Bass & Stogdill, 1990). Studying leadership in an organization provides value in understanding its relation to outcomes such as employee attitudes (Podsakoff, MacKenzie, & Bommer, 1996), individual performance (Tierney, Farmer, & Graen, 1999) and organizational performance (Day & Lord, 1988; Sully de Luque, Washburn, Waldman, & House, 2008). Leadership is suggested to be the underlying human factor key to organizational effectiveness (Hogan & Kaiser, 2005). In spite of the vast body of literature, much remains to be understood, especially understanding context (McCall & Hollenbeck, …

Crystallized Intelligence And Openness To Experience: Drawing On Intellectual-Investment Theories To Predict Job Performance Longitudinally, Christopher B. Patton

Doctoral Dissertations

Various approaches to conceptualizing and measuring intelligence have been utilized throughout history. Despite the plethora of intelligence theories, the field of industrial and organizational (I-O) psychology has been largely dominated by the psychometric tradition of intelligence and Spearman's general factor theory of intelligence (g). Moreover, other approaches to intelligence (e.g., the developmental perspective) have generally been ignored by I-O psychology. This is puzzling given the widespread acceptance among I-O psychologists of intelligence's substantial and increasing importance in the modern workplace.

Supported by a vast amount of research, g has often been recognized as the single best predictor of …

Can Genetics Predict Response To Complex Behavioral Interventions? Evidence From A Genetic Analysis Of The Fast Track Randomized Control Trial, Dustin Albert, Daniel W. Belsky, D. Max Crowley, Shawn J. Latendresse, Fazil Aliev, Brien Riley, Cuie Sun, Danielle M. Dick, Kenneth A. Dodge

Psychology Faculty Research and Scholarship

Early interventions are a preferred method for addressing behavioral problems in high-risk children, but often have only modest effects. Identifying sources of variation in intervention effects can suggest means to improve efficiency. One potential source of such variation is the genome. We conducted a genetic analysis of the Fast Track randomized control trial, a 10-year-long intervention to prevent high-risk kindergarteners from developing adult externalizing problems including substance abuse and antisocial behavior. We tested whether variants of the glucocorticoid receptor gene NR3C1 were associated with differences in response to the Fast Track intervention. We found that in European-American children, a variant …

A Parent-Child Therapy Program For Latino Families, Michael P. Fung

Dissertations (1934 -)

This study used a randomized control design with treatment and wait-list conditions to evaluate the efficacy of a culturally-adapted version of the Early Pathways program (Fox & Gresl, 2014), an in-home, parent-child therapy program with 137 at-risk Latino children under the age of six referred for severe behavior and emotional problems, such as aggression, oppositional behavior, self-injury and property destruction. Early Pathways directly engaged the parent-child dyad, emphasizing parent-directed training and child-engagement activities, such as psycho-education, child-led play, and cognitive-behavioral strategies. Cultural modifications included establishing community partnerships to identify Latino family needs, translation of materials, offering bilingual services, acculturation assessment, …

Explicit And Inferred Motives For Nonsuicidal Self-Injurious Acts And Urges In Borderline And Avoidant Personality Disorders, Avigal Snir, Eshkol Rafaeli, Reuma Gadassi, Kathy R. Berenson, Geraldine Downey

Psychology Faculty Publications

Nonsuicidal self-injury (NSSI) is a perplexing phenomenon that may have differing motives. The present study used experience sampling methods (ESM) which inquired explicitly about the motives for NSSI, but also enabled a temporal examination of the antecedents/consequences of NSSI; these allow us to infer other motives which were not explicitly endorsed. Adults (n = 152, aged 18–65) with borderline personality disorder (BPD), avoidant personality disorder (APD), or no psychopathology participated in a 3-week computerized diary study. We examined 5 classes of explicit motives for engaging in NSSI, finding support primarily for internally directed rather than interpersonally directed ones. We then …

Sex Differences In Placental Epigenetic Regulation Of Leptin Hormone Are Associated With Elevated Maternal Gestational Weight Gain, Nicole E. Douthit, Nicki Aubuchon-Endsley Ph.D. (Mentor)

Idaho Conference on Undergraduate Research

In utero epigenetic factors affect health and development, though sex differences in epigenetic effects of prenatal maternal health may exist for placental hormones. Specifically, maternal prenatal obesity affects expression of placental leptin hormone genes, which play a unique role in metabolism and appetite. However, the effects of such expression on infant neurobehavioral development differ by offspring sex.

Therefore, we examined sex differences in the effects of maternal gestational weight on placental leptin gene methylation. Data (n=155) were taken from the Behavior and Mood in Mothers and Behavior in Infants Study. Maternal pre-pregnancy weight was self-reported, while delivery weight …

Maternal Prenatal Depression And Anxiety Affect Neonatal Neurobehavior, Shelby Siddall, Jason Gibbs, Aimee Martin, Nicki Aubuchon-Endsley (Mentor)

Idaho Conference on Undergraduate Research

Prenatal depression and anxiety have been linked to impaired infant neurobehavior including altered attention, responsivity, and quality of movement. No known studies have assessed individual and joint effects of prenatal depressive and anxiety on neonatal neurobehavioral outcomes. The current study compared these outcomes among (1) mothers diagnosed with comorbid Depressive and Anxiety Disorders, (2) mothers diagnosed with only Depressive Disorders, (3) mothers diagnosed with only Anxiety Disorders, and (4) mothers with no prenatal diagnosis.

Maternal prenatal diagnoses were assessed by the SCID-I. Offspring neurobehavior was assessed from 1-2 to 30 days using the NNNS. There was a between-subject's effect ( …

It used in-depth narrative interviews to elicit my responses to lived experiences from growing up in Mexico to my current teaching position. Thematic …

Age Differences In The Impact Of Emotional Cues On Subsequent Target Detection, Brandon Wade Coffey

Masters Theses & Specialist Projects

Emotional cues within the environment capture our attention and influence how we perceive our surroundings. Past research has shown that emotional cues presented before the detection of a perceptual gap can actually impair the perception of elementary visual features (e.g., the lack of detail creating a spatial gap) while simultaneously improving the perception of fast temporal features of vision (e.g., the rapid onset, offset, and re-emergence of a stimulus). This effect has been attributed to amygdalar enhancements of visual inputs conveying emotional features along magnocellular channels. The current study compared participants’ ability to detect spatial and temporal gaps in simple …

Dynamic Tactile Information Is Sufficient For Precise Curvature Discrimination, Jacob R. Cheeseman

Masters Theses & Specialist Projects

Our tactile perceptual experiences occur when we interact, actively and passively, with environmental objects and surfaces. Previous research has demonstrated that active manual exploration enhances the tactile perception of object shape. Nevertheless, the factors that contribute to this enhancement are not well understood. The present study evaluated the ability of 14 older adults to discriminate curved surfaces by actively feeling objects with a single index finger and by passively feeling objects that moved relative to a restrained finger. The curvature discrimination thresholds obtained for passive-dynamic touch were significantly lower than those that occurred during active-dynamic touch. This result demonstrates that …

Making The Connection Between Disordered Personalities And Interpersonal Dysfunction: A Relational Study, Meggie P. Rowland

Doctoral Dissertations

The Diagnostic and Statistical Manual of Mental Disorders (DSM) is a constantly evolving record of the conceptualization of mental problems. With each new edition, researchers seek to come ever closer to defining complex dysfunctional human behaviors as they occur in nature. Significant evidence suggests that the current conceptualization of personality disorders (PDs) as defined in the DSM-5 is not adequately capturing these disorders, leading to inaccurate diagnosis and ineffective treatment outcomes. This evidence has led to the formation of a new diagnostic model of PDs which is outlined in Section III of the DSM-5 under conditions requiring further study. Several …

Toward A Relational Humanism, Kenneth J. Gergen

Psychology Faculty Works

Humanist conceptions of the person evolve across history. Whereas humanism has served a pivotal role in the caregiving professions, its individualist emphasis now stands as an impediment to its future. Proposed is a relational reconceptualization of the person, placing relational as opposed to individual well-being at the forefront of humanists' concerns.

Effects Of Feedback Assisted Treatment On Post-Treatment Outcome For Eating Disordered Inpatients: A Follow-Up Study, Megan Michelle Bowen

Student Works

Research on the effects of progress feedback and clinician problem-solving tools on patient outcome has been limited to a few clinical problems and settings (Shimowaka, Lambert & Smart, 2010). Only one randomized clinical trial has examined feedback-assisted treatment in an inpatient eating-disordered population. Results from this study suggested that those who received feedback-assisted (Fb) treatment were more likely to meet Jacobson and Truax's (1991) criteria for recovery than participants in the treatment-as-usual (TAU) condition; however, while these interventions appear to have worked well in the inpatient setting, the long-term effects of this treatment have not been investigated. This is especially …

Factors Associated With Family Counseling Practices: The Effects Of Training, Experience, And Multicultural Counseling Competence, Amanda A. Brookshear

Counseling & Human Services Theses & Dissertations

The ACA code of ethics encourages the inclusion of family in the therapeutic process when doing so can be considered positive (ACA, 2014). Additionally, family dynamics are an important component of counseling for clients from diverse cultural backgrounds. A critical review of the literature reveals that there are differences between conceptual and physical inclusions of families in counseling. Counselors can use a family systems theoretical lens and or incorporate family-based interventions. The purpose of this study was to investigate how counselors include families in counseling and what factors are associated with family counseling practice. Variables assessed include training and coursework, …

Examining Possible Perceptual Proxies Of Flow State, Devin Michael Gill

Theses and Dissertations

Nakamura and Csikszentmihalyi (2002) define flow as an individual's deep engagement in an intrinsically rewarding activity. McGonigal (2011) suggests that video games are flow elicitors. If video games are flow elicitors, then spatial, agentic, and temporal perception required for game play may relate to flow in predictable manners. Over two experiments, a simple video game with contextual (i.e., implied friction) and conceptual (i.e., ambiguous stimulus labeled either bullet-train or house) manipulations was used to elicit flow. Effects of the manipulations were assessed trial-by-trial on two dimensions of flow (i.e., agency and temporal perception) and spatial planning, as well as an …

Dualism And Doctrine, Dov Fox, Alex Stein

Indiana Law Journal

What kinds of harm among those that tortfeasors inflict are worthy of compensation? Which forms of self-incriminating evidence are privileged against government compulsion? What sorts of facts constitute a criminal defendant’s intent? Existing doctrine pins the answer to all of these questions on whether the injury, facts, or evidence at stake are “mental” or “physical.” The assumption that operations of the mind are meaningfully distinct from those of the body animates fundamental rules in our law.

A tort victim cannot recover for mental harm on its own because the law presumes that he is able to unfeel any suffering arising …

The Effects Of Alcohol On The Interpretation Of Social And Emotional Cues: A Field Study Of College Student Drinking, Emotion Recognition, And Perceptions Of A Hypothetical Sexual Assault, Alexander James Melkonian

Graduate Theses and Dissertations

Alcohol use and abuse among emerging adults is highly correlated with increased risk for sexual victimization. Alcohol myopia theory has been used to explain impairments in Social information processing resulting in decreased attention to environmental Social cues including risk factors for sexual assault as well as facial emotional recognition. Those with deficits in Social information processing may be at particular risk for the misperception of salient risk factors for sexual assault by victims, perpetrators, and bystanders when intoxicated. In this naturalistic field study, participants who had been consuming alcohol were recruited to engage in tasks of facial emotion recognition and …

Under New System, Bridges Build You, Steven Toaddy, Joseph A. Allen

Psychology Faculty Publications

Let’s take a page from the lessons that public-speaking classes convey, viz. “tell them what you’re going to tell them, tell them, and then tell them what you’ve told them.” Thus:

• In response to calls from SIOP’s past leadership, the Bridge Builders group—one designed to spread awareness and understanding of I-O psychology to many different audiences—was developed and counts among its members many of us from SIOP. President Steve Kozlowski’s vision for the organization in the coming years dovetails well with the objectives of Bridge Builders.
• Bridge Builders have been doing some really cool things recently; these were …

Influence Of Caregiver Activation On Health Of Informal Caregivers Of Persons With Alzheimer’S, Trinity Rose Parker

Doctor of Psychology (PsyD)

Abstract Caregiver activation is related to a caregiver’s knowledge, skill and confidence to provide multiple levels of care of another individual. To date there is little research assessing caregiver activation within the population of informal caregivers of Alzheimer’s patients. Forty-four informal caregivers of persons with Alzheimer’s were recruited through caregiver resource centers and online communities in the state of Oregon, completed a self-report survey. The purpose of this study was to identify the predictive qualities and influence of caregiver activation on informal caregiver physiological and psychological health as well as positive health behaviors. General health, emotional wellbeing, self-efficacy, and caregiver …

I Judge, Therefore I React: An Experimental Investigation Of Acceptance, Jennifer Ann Shaver

Graduate Theses and Dissertations

The present study was designed to provide empirical tests of some of the mechanisms thought to operate in mindfulness-based treatments. Specifically, I tested the hypothesis that appraising distress judgmentally (as a needless and useless indication of personal weakness) would be associated with experiencing meta-distress (e.g., feeling ashamed about being distressed), which would, in turn, be associated with increased experiential avoidance (i.e., suppression or distraction from the distress) and shorter distress tolerance. In addition, I examined the hypothesis that compassionately appraising distress (as normal, understandable, and potentially a source of growth) would be associated with spending more time curiously exploring that …

Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber

Undergraduate Honors Theses

Relatively few studies have investigated the relationship between executive functioning (EF) and language development, and even fewer have researched hot and cool EF as a predictor language development. This study is an investigation into the relationship between EF and language development in preschool aged children. More specifically, the ability for hot or cool EF to predict language, this will be the focus of the study. It was found that hot EF was a better predictor of language development in preschool aged children.

Improving Dynamic Decision Making Through Training And Self-Reflection, C Dominik Guess, Sarah J. Donovan, Dag Naslund

Psychology Faculty Research and Scholarship

The modern business environment requires managers to make effective decisions in a dynamic and uncertain world. How can such dynamic decision making (DDM) improve? The current study investigated the effects of brief training aimed at improving DDM skills in a virtual DDM task. The training addressed the DDM process, stressed the importance of self-reflection in DDM, and provided 3 self-reflective questions to guide participants during the task. Additionally, we explored whether participants low or high in self-reflection would perform better in the task and whether participants low or high in self-reflection would benefit more from the training. The study also …

Behavioral And Pharmacological Investigation Of Anxiety And Maternal Responsiveness Of Postpartum Female Rats In A Pup Elevated Plus Maze, Yu Yang, Jingxue Qin, Weihai Chen, Hong Chen, Ming Li

Department of Psychology: Faculty Publications

The present study investigated the validity of a novel pup-based repeated elevated plus maze task to detect reduced anxiety and increased maternal responsiveness in postpartum female rats and explored the roles of dopamine D2, serotonin transporter and GABA/benzodiazepine receptors in the mediation of these processes. Sprague–Dawley postpartum or nulliparous female rats were tested 4 times every other day on postpartum days 4, 6 and 8 in an elevated plus maze with 4 pups or 4 pup-size erasers placed on each end of the two open arms. When tested with erasers, untreated postpartum mother rats entered the open arms proportionally more …
