Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis
Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis
Master's Theses
Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …
Measurement Invariance Of Assessment Center Ratings: Consistency Of Dimensional Constructs Across Exercises, Jin Lee
Master's Theses
The criterion-related validity of assessment centers (ACs) has been consistently supported. However, there has been an ongoing debate about AC construct validity in regard to low dimension variance and overriding exercise variance. Many studies that showed weak dimension effects in ACs have been based on the multitrait-multimethod (MTMM) framework which posits cross-situational variance as error and all capability dimensions can be equally represented from different exercises. The goal of this study is to introduce a measurement invariance (MI) framework for evaluating the construct validity of AC dimensions. Specifically, MI analysis was used to test whether the construct meaning of AC …
Effects Of Neonatal Hypoxic Ischemic Brain Injury On Spatial Working Memory, Amanda L. Smith
Effects Of Neonatal Hypoxic Ischemic Brain Injury On Spatial Working Memory, Amanda L. Smith
Master's Theses
Children born prematurely or at very low birth weight (VLBW) have an increased risk for hypoxic ischemic brain injury (HI). HI refers to a lack of adequate blood and oxygen flow in the brain. HI can also occur in the term infant due to birth complications such as prolonged labor, placental dysfunction, or cord prolapse. In both populations (though exact patterns of neuropathology vary) brain damage is likely to occur in the form of decreased hippocampal and cortical volume, and enlargement of the ventricles (Kesler et al., 2004, Nagy et al., 2009). Resulting neuropathology can in turn lead to cognitive …
A Practical Scale For Multi-Faceted Organizational Health Climate Assessment, Zandra M. Zweber
A Practical Scale For Multi-Faceted Organizational Health Climate Assessment, Zandra M. Zweber
Master's Theses
The current study sought to develop a practical scale to measure workplace health climate in a way that has not previously been conceptualized – as a three-faceted approach from the employee perspective serving as an indicator of a healthy organization. The goal was to create a short, useable yet comprehensive scale that could translate into practical use by organizations and occupational health professionals planning workplace interventions. To accomplish this, the proposed multi-faceted organizational health climate scale (MOHCA) assesses three-facets which match up with three organizational levels: 1) organization 2) supervisor and 3) workgroup. Ten items were developed and tested on …
Effects Of Practice With Imposed Communication Delay On The Coordination And Effectiveness Of Distributed Teams, Megan L. Dove-Steinkamp
Effects Of Practice With Imposed Communication Delay On The Coordination And Effectiveness Of Distributed Teams, Megan L. Dove-Steinkamp
Master's Theses
The current study tested whether introduction of audio transmission delays during skill acquisition would benefit the performance effectiveness of distributed teams in a novel transfer context. Two-person university student teams (N=40) performed a simulated firefighting task in 4 practice trials and a novel transfer condition. Intra-team communications were systematically perturbed with closed-loop transmission delays ranging from 2 to 6 seconds. On average, teams were able to improve performance over time despite transmission delay, with significant differences in performance observed between certain groups both over the course and at the end of the experiment: Short (2s blocked) practice delay was associated …
Negative Event Appraisals, Cognitive Processing, And Adjustment, Kristen E. Riley
Negative Event Appraisals, Cognitive Processing, And Adjustment, Kristen E. Riley
Master's Theses
Appraisals of stressful events are linked to their adjustment to those stressful events. Appraisals can include perceptions of an event as threatening, uncontrollable, controllable, central, or challenging (Peacock & Wong, 1990). Many studies have examined effects of these appraisals on adjustment and cognitive processing (Aldwin, 2007; Lazarus, 1993; Tan, Jensen, Thornby, & Anderson, 2005), and a few have suggested that cognitive processing mediates relationships between appraisals and adjustment (Peacock & Wong, 1996). We tested cognitive processing in mediation models between appraisals and adjustment, and compared to active coping, in the context of ongoing stressors. Active coping appears to be particularly …
Reducing Knowledge Overconfidence By Reducing The Threat Of Knowledge Cue Utilization, Christopher Neil Burrows
Reducing Knowledge Overconfidence By Reducing The Threat Of Knowledge Cue Utilization, Christopher Neil Burrows
Master's Theses
Overconfident judgments are common. We are often more confident about things than we should be, and this may lead us to make maladaptive decisions. Debiasing confidence by cuing people in to how confident they should be could help people make better choices. However, people may be unwilling to accept debiasing information if doing so implies their own ignorance. This study examined whether self-affirmation can buffer people against threats to self-image, helping people to accept debiasing cues. I hypothesized that combining a cue with self-affirmation would lead to enhanced debiasing over cues or self-affirmation alone. In order to investigate this hypothesis, …

Repetitive And Stereotyped Behaviors From Age 2 To Age 4: A Look At The Development Of High- And Low-Level Repetitive Behaviors In Children With Autism Spectrum Disorders, Kelley Knoch
Master's Theses
Restricted and repetitive behaviors (RRBs) are core features in autism spectrum disorders (ASD). Previous literature has subdivided RRBs into low and high levels. Low-level behavior is characterized by a repetition of movement, such as stereotyped movements, whereas high-level behavior includes insistence on sameness and rigid adherence to a routine. There is conflicting evidence frequency and severity of RRBs in early development in children with ASD. In the current study, we examined developmental differences in the frequency and severity of RRBs in children with ASD (n = 109) compared to children with developmental delays (DD) (n= 34). Participants were evaluated at …

Mothers Do Not Drive The Development Of Adult Homesign Systems: Evidence From Comprehension, Emily Carrigan
Mothers Do Not Drive The Development Of Adult Homesign Systems: Evidence From Comprehension, Emily Carrigan
Master's Theses
Studying the communication systems that arise in spontaneously occurring cases of degraded linguistic input can help clarify human predispositions for language. Some deaf individuals born into hearing families, who do not receive conventional linguistic input, develop gestures, called “homesign,” to communicate. We examined homesign systems used by four deaf Nicaraguan adults (ages 15-27), and evaluated whether homesigners’ hearing mothers are potential sources for these systems. Study One measured mothers’ comprehension of descriptions of events (e.g., “A man taps a woman”) produced in homesign and spoken Spanish. Mothers comprehended spoken Spanish descriptions (produced by one of their hearing children) better than …
The Multi-Scale Dynamics Of Executive Function, Jason Anastas
The Multi-Scale Dynamics Of Executive Function, Jason Anastas
Master's Theses
Cognitive control is a central issue in developmental psychology. Traditional theories of psychology solve this problem by positing a top-down central executive, which coordinates cognitive resources in pursuit of goals. We propose an alternative explanation: cognitive control arises from physical interactions across many different timescales within the system. College and preschool aged participants were asked to complete a simple executive function task, card sorting. We found that multi-scale physical interactions differed depending on experimental constraints, and that executive function in these cases was driven primarily by flexibility in multi-scale interactions, rather than the dominance of one scale. This suggests that, …

Racial/Ethnic Differences In Possible Selves Of Diverse Adolescents: Implications For Higher Education And Mental Health, Viana Y. Turcios-Cotto
Racial/Ethnic Differences In Possible Selves Of Diverse Adolescents: Implications For Higher Education And Mental Health, Viana Y. Turcios-Cotto
Master's Theses
There are striking disparities in the academic achievement of American youth, with Latino and Black adolescents attaining higher education at vastly lower rates than White adolescents. Though numerous reasons exist for these educational disparities this study examines possible selves as they may relate to educational achievement among Latinos. Specifically, this study investigates: a) racial/ethnic differences in the content and themes of expected possible selves held by young adolescents; b) within group differences among Latino students and their expected possible selves; c) racial/ethnic differences in the relation between higher education possible selves and current mental health adjustment. Written responses reflecting types …
The Impact Of Breast Cancer Screening On Sleep, Affect, And Immune Functioning, Caitlin Burbridge
The Impact Of Breast Cancer Screening On Sleep, Affect, And Immune Functioning, Caitlin Burbridge
Master's Theses
Despite great strides that have been made over the past several decades in terms of diagnosis and treatment, breast cancer remains the most commonly diagnosed cancer in American women and the second leading cause of cancer-related mortality for women in the United States. Although the benefits of early detection of breast cancer have been clearly established, the advantages of screening must also be weighed against a potential corresponding negative psychological impact of screening procedures. The purpose of the present study was to further investigate the impact of breast cancer screening on previously unstudied or understudied aspects of psychological and physiological …

Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo
Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo
Master's Theses
Individuals with Autism Spectrum Disorders (ASD) have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning appears potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to the transitional probabilities between speech sounds. This study aimed to investigate the relationship between implicit learning and current language abilities in school-aged children with autism (n = 17) and typical development (n = 24) using a well-studied artificial language learning task. Results suggest that the ASD and TD groups were equally able to implicitly learn transitional probabilities from a lengthy …
Testing For A Descriptive And Injunctive Norm Interaction In Promoting Health Behavior, Robert E. Low
Testing For A Descriptive And Injunctive Norm Interaction In Promoting Health Behavior, Robert E. Low
Master's Theses
Social norms-based interventions have demonstrated efficacy as tools for behavior change interventions. Nonetheless, there is some theoretical and empirical evidence that the efficacy of injunctive norms-based appeals can be undermined by their tendency to 1) arouse psychological reactance among participants, and 2) inadvertently imply that few others are completing the target behavior. The author hypothesizes that supplementing an injunctive appeal with evidence of a supporting descriptive norm will counteract these problematic tendencies. The present research describes a test of of this hypothesis in the context of an intervention to fight H1N1 on campus. Boxes of sanitizing keyboard wipes were placed …
Language Typology And Sentence Frame Effects On Motion Verb Interpretation In Grade Schoolers, Emma C. Kelty
Language Typology And Sentence Frame Effects On Motion Verb Interpretation In Grade Schoolers, Emma C. Kelty
Master's Theses
Most English descriptions of motion events express manner in the main verb and path in a prepositional phrase, as in “She skips out of the house”. However, the same event can be described differently if a different syntactic frame is used: “She exits the house”. While young children have been found to interpret novel motion verbs according to the syntactic frame information, adults have been found to rely somewhat more on the overall language pattern, or typology (Hohenstein et al., 2004; Naigles & Terrazas, 1998). Grade schoolers have not been examined in this paradigm, and their linguistic abilities suggest that …

Antecedents And Continuity Of Compliance In Preschoolers, Lauren Gindin
Antecedents And Continuity Of Compliance In Preschoolers, Lauren Gindin
Master's Theses
Self-regulation, and compliance behavior specifically, has been implicated in the development of successful socialization. Difficulty self-regulating has led to negative outcomes in areas such as academic success and mental health, and a number of possible contributors, such as temperament, maternal sensitivity and attachment, have been identified. In this study, we examined these possible predictors of preschool compliance behavior through causal modeling utilizing a large and diverse longitudinal dataset from the NICHD Study of Early Child Care and Youth Development. We aimed to predict compliance and delay of gratification performance in children across 2, 3 and 4.5 years of age by …
Understanding The Behavioral Determinants Of Retention In Hiv Care: A Qualitative Evaluation Of The Situated Information, Motivation, Behavioral Skills Model Of Care Initiation And Maintenance, Laramie Smith
Master's Theses
The goal of this study is to identify the content and context of critical informational, motivational, and behavioral skills related facilitators and barriers influencing retention in HIV care in an inner-city clinic population receiving clinic- and outreach-based HIV care services. Elicitation of retention-relevant factors was guided by the Situated Information-Motivation-Behavioral Skills model of Care Initiation and Maintenance, using qualitative in-depth semi-structured interviews. Deductive and inductive content coding were used to identify important theory-based dynamics of retention in HIV care and to identify factors discussed as important to retention in HIV-care that were not well specified by the model. Participants’ experiences …
Distance Judgments For Joint Action: The Perceptual Consequences Of Anticipated Coordination, Benjamin R. Meagher
Distance Judgments For Joint Action: The Perceptual Consequences Of Anticipated Coordination, Benjamin R. Meagher
Master's Theses
Recent perception research has revealed that judgments of distance are influenced by the energetic cost required to perform particular actions, such as walking, across these distances (Proffitt, 2006b). However, this prior research has focused almost exclusively on the perceptual consequences of solo action, despite the fact that individuals regularly become embedded within social units for the purpose of joint action (Richardson, Marsh, & Schmidt, 2005). In two experiments, the current work sought to test the hypothesis that forming a social unit creates a new perception-action system with distinct perceptual attunement of the environment scaled to the unit’s action-potential. Participants, accompanied …
The Morally Contaminating (And Motivating) Influence Of Hate Groups In The U.S., Andrew L. Stewart
The Morally Contaminating (And Motivating) Influence Of Hate Groups In The U.S., Andrew L. Stewart
Master's Theses
A growth in the number of hate groups that operate in the United States over the past decade counters many researchers’ claims that overt prejudice and discrimination no longer have influence. In this thesis, we explore how people react with moral outrage and moral cleansing toward hate groups’ moral transgressions of racial egalitarianism—a strong sacred value among those who desire group-based equality. Across two experiments, we find that people perceive hate groups as immoral social agents, and people express moral outrage against them. We also find that people who were morally contaminated by hate groups (i.e., by being led to …
A Relational Perspective On Sex Stereotyping, Jessica Kang
A Relational Perspective On Sex Stereotyping, Jessica Kang
Master's Theses
The current study adopts a relational perspective of sex stereotyping by taking into account the perceiver’s group membership, the target group, and the content of the stereotype. We asked women and men to report their personal beliefs about men and women on three characteristics: competence, warmth and morality. The results showed that participants were engaging in three different patterns of sex stereotyping: traditional sex stereotyping (both sexes rated similarly by both male and female participants on traditional stereotypes), traditional in-group favoring sex stereotyping (participants favor his/her own group on a stereotype traditionally associated with his/her group), and counter-traditional sex stereotyping …
Effect Of Distress, Referral Source, And Pressure To Attend Therapy On Motivation To Change, Lyn E. Moore
Effect Of Distress, Referral Source, And Pressure To Attend Therapy On Motivation To Change, Lyn E. Moore
Master's Theses
Psychotherapy is an effective form of treatment, yet difficulties with engagement and dropout continue to plague the field. Poor outcomes are more likely to be achieved by poorly motivated clients and those who are mandated to attend therapy (Prochaska, DiClemente, & Norcross, 1992). This study examined links between motivation to change, initial levels of distress, referral source, and pressure to attend therapy in a sample of 587 individuals who attended therapy at a university-based counseling center in the Northeast. Results indicated a relationship between distress and motivation to change as well as a link between the perceived pressure felt by …

Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson
Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson
Master's Theses
Three experiments were conducted to investigate how changes in bodily states might be related to perceptions of infant vocalizations. In Study 1, participants were asked to hold a pencil between their lips, mimicking a smile, while listening to infant crying. Although there were no embodied effects for perceptual ratings, results indicated that this manipulation decreased participants’ self-reported, negative affect. In Study 2, participants were played both infant crying and birdsong while exposed to similar embodied manipulations, including activation of muscles related to approach and withdrawal behavior. There were no embodied effects for ratings of crying or for affect. Comparing Study …
Effects Of Delayed Auditory Feedback On Young Infants’ Crying, Sarah M. Sanborn
Effects Of Delayed Auditory Feedback On Young Infants’ Crying, Sarah M. Sanborn
Master's Theses
Neural control of newborn crying has typically been considered to originate primarily in the lower brain centers, although support for this assumption is limited. To address this, the present study manipulated newborn infants’ perceptual experience during a cry bout through use of delayed auditory feedback (DAF). Atypical cry productions during DAF would suggest that newborn crying is under higher levels of cortical control than previously assumed. Infants’ spontaneous crying was recorded for 2 minutes at 4 weeks of age (n=16) and again at 8 weeks of age (n=17) using an ABA design, alternating synchronous feedback with DAF. Standard repeated-measures 2 …
