Habitat Use By Bottlenose Dolphins, Tursiops Truncatus, In Roanoke Sound, North Carolina, Shauna Marisa Mcbride

Dissertations

Information on the habitat use of a species is important to develop conservation efforts and management strategies for that species. Roanoke Sound, North Carolina is primarily a seasonal habitat for bottlenose dolphins, Tursiops truncatus, from late spring to early fall, but little information is known about how dolphins use this area. Transect survey data and opportunistic survey data collected by the Outer Banks Center for Dolphin Research from 2009 to 2015 were used to analyze dolphin habitat use. The objectives of this project were to: 1) identify areas that were important to dolphins, 2) determine which behaviors were observed …

Using Digital Performance Feedback To Increase Teacher Treatment Integrity, Heather Marie Whipple

Master's Theses

In intervention research, assessing treatment integrity is important to establish functional control of the independent variable and make accurate decisions regarding treatment effectiveness. This study examined the effects of digital performance feedback (DPF) as a follow-up strategy for teachers to increase integrity. A multiple baseline design was utilized to determine the effectiveness of this strategy. Results from this study expanded previous literature on ways to promote treatment integrity and help move toward a science of intervention implementation. The primary dependent variable measured was treatment integrity. Student behavior was also assessed to determine if there is a relationship between treatment integrity …

The Effects Of Tootling Combined With Public Posting In High School Classrooms, Sarah Joan Wright

Master's Theses

A traditional tootling procedure was implemented along with a public posting component to determine the effects on academically engaged, disruptive, and passive off task behaviors in four general education high school classrooms. The study employed an A/B/B+C multiple baseline design across classrooms. The primary focus of the study was to assess potential increases in academically engaged behavior across intervention conditions. Students in the traditional tootling phase (B) were instructed to report on their peers’ positive, prosocial behaviors. At the end of the class period, the teacher silently read through the tootles and added the total toward the group goal. When …

Evaluating The Independent Group Contingency: “Mystery Student” On Improving Behaviors In Head Start Classrooms, Jamie Pasqua

Master's Theses

An increasing number of preschool children exhibit challenging behavior in the classroom. Head Start children are particularly at risk for emotional and behavioral disorders due to numerous risk factors. Unfortunately, some preschool teachers are ill equipped to manage the challenging behaviors that preschool children exhibit. The current study investigated the effects of the group contingency, “Mystery Student,” on improving preschool classroom behaviors. The Mystery Student intervention is a novel, independent group contingency, with an added randomized component. An ABAB reversal design was employed to determine how effective the Mystery Student intervention was at decreasing the disruptive behaviors and increasing the …

Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon

Master's Theses

Vision and haptics play a central role in perceiving environmental layout to guide action. Hajnal, Wagman, Doyon, and Clark (2016) demonstrated that visual perception of stand-on-ability is accurate compared to action capabilities, whereas haptic perception of stand-on-ability reliably underestimates action capabilities. This finding contradicts Gibson’s (1979) theory of equivalence in perceptual systems, which suggests that perception should be equivalent regardless of modality. Previous comparisons of visual and haptic perception tested the modalities in isolation. The current experiment directly compares visual to haptic perception of stand-on-ability by using one perceptual system to estimate the other. Observers viewed a surface set to …

Generalization Of Teachers' Use Of Effective Instruction Delivery Following In Situ Training, Joy Kathleen Wimberly

Master's Theses

The efficacy of in situ training for increasing Head Start teachers’ use of effective instruction delivery in Head Start classrooms while evaluating concomitant increases in Head Start students’ compliance was examined in the current study. Of further interest was the extent to which Head Start teachers maintained and generalized accuracy of effective instruction delivery in untrained settings. Four Head Start teachers and four Head Start students served as participants in this study. A multiple baseline across participants was used to test the effects of in situ training on teachers’ accuracy of effective instruction delivery and students’ initiation compliance. Data were …

Altered Developmental Trajectories For Impulsivity And Sensation Seeking Among Adolescent Substance Users, Nora E. Charles, Stacy R. Ryan, Bethany C. Bray, Charles W. Mathias, Ashley Acheson, Donald M. Doherty

Faculty Publications

A number of studies have associated impulsivity and sensation seeking with level of substance use and risk for developing a substance use disorder. These relationships may be particularly apparent during adolescence, when developmental changes in impulsivity and sensation seeking occur at the same time as increased opportunities for substance use. To examine this, the current study measured impulsivity and sensation seeking from pre-adolescence to mid-adolescence in a sample of youth, the majority of whom were identified as being at risk for developing a substance use disorder based on their family history of substance use disorders. Youth were separated into those …

The Tootling Intervention With Classdojo: Effects On Classwide Disruptive Behavior And Academically Engaged Behavior In An Upper Elementary School Setting, Melissa Mchugh Dillon

Dissertations

The current study was designed to replicate and extend the literature on the effectiveness of a classroom intervention known as Tootling (Skinner, Skinner, & Cashwell, 1998) to include an interactive technological component, ClassDojo, to decrease disruptive classroom behavior as well as increase academically engaged behavior. Tootling is a peer-monitoring intervention that encourages students to report instances of appropriate behaviors they have seen their peers perform. Thus far, studies utilizing direct observation data to measure disruptive behavior during Tootling (Cihak, Kirk, & Boon, 2009; Lambert, 2014, Lambert el al., 2015, Lum et al., 2015; McHugh et al., 2014) have shown reductions …

“Eye For An Eye” Or “Turn The Other Cheek?” Exploring The Moderating Roles Of Revenge And Forgiveness When Examining Death Penalty Support And Religious Fundamentalism, William Howard Whited

Dissertations

Public attitudes towards the death penalty appear to influence the usage of legislative policies about this highly debated sanction in the United States. However, existing ways of measuring public opinion about the death penalty are limited in the information they provide. As such, one purpose of the study was to further develop the Revised Attitudes towards the Death Penalty Scale (RATDP), an instrument that measures level of support for the death penalty and is inclusive of the rationales that both proponents and opponents use to justify their stance. Support for a five-factor structure of the RATDP was found in an …

Predictors Of Alcohol Consumption, Use Of Protective Behavioral Strategies, And Alcohol-Related Sexual Consequences: A Gendered Social Learning Perspective, Kayla Darlene Moorer

Dissertations

Given the long standing gender differences in regard to alcohol-related behaviors and consequences, understanding how conformity to gender norms may predict alcohol-related outcomes is an important next step in developing effective prevention efforts aimed at reducing alcohol-related sexual consequences for college women. The current study examined the relationships among conformity to feminine and masculine gender norms and alcohol-related outcomes (harmful drinking patterns, protective behavior strategy use, and sex-related consequences) among college women. Another primary aim of the study was to determine the extent to which sex-specific alcohol expectancies mediated the associations between gender norms and alcohol-related outcomes. Participants were 421 …

Profiles Of Academic Commitment, Anna Jill Womack

Dissertations

Tinto (1993) found that only 15-25% of students who dropped out of college did so due to academic failure, while the reasons for leaving among the remaining group of students who dropped out were unknown. This suggests that the majority of students who drop out of college are likely doing so for reasons other than academic struggles. Researchers have suggested that individuals who are committed to their major are more likely to obtain a bachelor’s degree (Bowling, Beehr, & Lepisto, 2006; Den Hartog & Belschak, 2007; Duffy, Dik, & Steger, 2011; Goulet & Singh, 2002; Landrum & Mulcock, 2007), indicating …

The Associations Among Expressed Emotion, Relationship Satisfaction, Ptsd Symptoms, Alcohol Use, And Depression: A Longitudinal Investigation With A Military Sample, Laci Lee Zawilinski

Dissertations

PTSD in military personnel is highly prevalent and accompanied by elevated rates of additional issues such as depression, problematic alcohol use, and interpersonal relationship problems. Family members and spouses of military personnel have also been shown to be negatively impacted by PTSD symptoms. Previous research has indicated that family members and spouses’ expressed emotion regarding the PTSD patients’ symptoms negatively impacts treatment outcome in civilian populations. However, studies have yet to investigate the effect of expressed emotion on the course of PTSD symptoms and associated problems in military personnel. Therefore, the purpose of the present investigation was to examine the …

The Role Of Parental Locus Of Control In The Relations Among Early Childhood Temperament, Parenting Practices, And Child Externalizing Behavior, Amanda Kathryn Stary

Dissertations

Child externalizing behaviors are a common reason for children’s referral for mental health services, and parenting practices are a primary target of efficacious interventions. In turn, child temperament and parent beliefs, such as parental self-efficacy and locus of control, relate to use of specific parenting practices. The present study aimed to evaluate whether parental locus of control and related components moderate the indirect effect of preschool-aged children’s temperament on their externalizing behaviors through parenting practices. Specifically, child temperament was expected to predict parenting practices only at certain levels of locus of control. Female caregivers of 146 children ages 3-5 years …

The Impact Of Varieties Of Shame On Disordered Eating: Exploring The Influence Of Emotion Regulation And Self-Compassion, Tiffany Ann Hopkins

Dissertations

The current study examined the impact of specific forms of shame on severity of specific disordered eating behaviors, after controlling for depression and guilt, among women who engaged in restricting, binge-eating, purging/compensatory behaviors, or binge eating and purging in combination. Additionally, the study examined whether self-compassion and emotion regulation mediated the relation between various forms of shame and disordered eating severity. Finally, the study piloted an internet-based method of self-compassion induction. Participants (N = 518) were a convenience sample of women recruited from websites associated with eating disorders, who reported engagement in at least one disordered eating behavior in the …

Cultural Moderation Of The Relationship Between Anticipated Life Role Salience And Career Decision-Making Difficulties, Emily Anne Schmidtman

Dissertations

The perceived importance of, and commitment to, work and family roles has significant implications for the career decision-making difficulty (CDMD) of undergraduate college students. Additionally, cultural variables have been shown to influence undergraduate students’ anticipated life role salience (LRS) as well as the amount of difficulty experienced in making a career decision. Given this information, the current study assessed the relationship between LRS and CDMD specifically in terms of differences that may occur within this relationship for different cultural groups. Using a sample of college students (total N = 246), an online survey was used to gather information about their …

Predictive Effects Of Parenting Styles, Self-Regulation, And Resistance To Peer Influence On Drinking Behaviors In College Freshmen: A Social Learning Perspective, Saarah Danielle Kison

Dissertations

The first year of college may be a salient time period for the development of drinking practices in college populations. While parenting styles have been associated with global self-regulation, resistance to peer influence and college student drinking behaviors, a comprehensive evaluation of these relationships has yet to be established. Researchers have demonstrated that self-regulation acts as both a predictor and moderator of resistance to peer influence, which has been shown to be a more proximal predictor of drinking behaviors. While relationships between global self-regulation, parenting and drinking have been empirically established, less attention has been given to specific methods of …

Emotion-Related Factors As Mediators In The Relation Between Family Stress And Adolescent Externalizing Problems, Kristy Marie Disabatino

Dissertations

Adaptive regulation of emotions, maternal depression, parenting stress, and environmental stress have all been related to adolescent psychosocial outcomes. Considering these established relations, the current study examined serial mediation models in which it was hypothesized that (1) maternal distress or community stress (examined in separate models) would positively relate to adolescent externalizing behaviors directly and (a) indirectly through maladaptive maternal emotion socialization (ES) practices (i.e., magnify, neglect, and punish), (b) indirectly through adolescent emotion regulation (ER) difficulties, and (c) indirectly through both maternal ES practices and adolescent ER difficulties; (2) maternal distress or community stress would positively relate to adolescent …

The Effect Of Auditory Stimulation On Sleep Disruption In West Indian Manatee (Trichechus Manatus Latirostris), Natalija Lace

Dissertations

Florida manatees inhabit waterways where motorized boats are common. Although manatee mortalities resulting from boat strikes are well documented, the effect of boat noise on some manatee behaviors, including rest, has not been investigated. This study focuses on rest behavior and used a playback experiment with four manatees at the Lowry Park Zoo in Florida. We tested their responses to playback stimuli of either boat noise, silence, or manatee calls. A playback trial was initiated when the focal animal showed behavioral characteristics of rest.

Results showed that rest was interrupted in response to the playback of boat noise for each …

Multi-Sensory Emotion Recognition With Speech And Facial Expression, Qingmei Yao

Dissertations

Emotion plays an important role in human beings’ daily lives. Understanding emotions and recognizing how to react to others’ feelings are fundamental to engaging in successful social interactions. Currently, emotion recognition is not only significant in human beings’ daily lives, but also a hot topic in academic research, as new techniques such as emotion recognition from speech context inspires us as to how emotions are related to the content we are uttering.

The demand and importance of emotion recognition have highly increased in many applications in recent years, such as video games, human computer interaction, cognitive computing, and affective computing. …

Implementing A Positive Variation Of The Good Behavior Game With The Use Of A Computer-Based Program, Shauna Lynne

Dissertations

The Good Behavior Game (GBG) is an interdependent group contingency designed to address behavioral concerns. The vast majority of published findings on the GBG have supported its effectiveness in decreasing disruptive behavior in classroom settings. The purpose of this study was to investigate the effectiveness and the social validity of a positive variation of the GBG in which teachers were asked to use ClassDojo to manage each team’s progress. ClassDojo is a computer-based program that enables teachers to track student behavior and monitor progress by way of a virtual system. Dependent variables included class-wide disruptive and academically engaged behavior (AEB), …

Assessing U.S. Veterans' Work Role Functioning: Influences Of Posttraumatic Stress, Sense Of Coherence, And Vocational Identity, Lauren Kelly Osborne

Dissertations

Since beginning military operations in Iraq and Afghanistan following the September 11, 2001 terrorist attacks that now characterize the Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) combat eras, unique stressors and conditions have faced service members. Advancements in military medicine have resulted in greater survival rates of combat veterans, but have also increased rates of chronic psychological distress (Schnurr, Lunney, Bovin, & Marx, 2009). Research regarding these concerns has increased as these service members are now returning home and re-entering civilian life and many studies show the detrimental effects on psychosocial functioning following combat including employment difficulties. As …

The Effects Of Peer-Mediated Check-In, Check-Out With A Self Monitoring Component On Disruptive Behavior And Appropriate Engagement In The Classroom, Chandler Erin Mclemore

Dissertations

Check-In/Check-Out (CICO) is a commonly used Tier II behavioral intervention within public school settings. The present study evaluated the use of an alternative method of service delivery for CICO that included peers as interventionists. Self-monitoring was an additional intervention component, utilized in order to reduce teacher response effort associated with intervention implementation. Three target student/peer interventionist dyads served as participants (one elementary school dyad, one middle school dyad, and one high school dyad). Direct observation data were collected, and the effects of peer-mediated CICO were evaluated with an ABAB design. Social validity measures were also completed by each teacher as …

The Influence Of Informant And Measurement On The Relations Among Adolescent Narcissism, Prosocial Behavior, And Emotional And Social Intelligence, Rebecca Lynn Kauten

Dissertations

Adolescent narcissism has been extensively linked with aggression, but its relation with more positive behavioral correlates has been largely overlooked in the literature. Some research has investigated the divergent adaptive and maladaptive personality and behavioral correlates of non-pathological and pathological (i.e., grandiose, vulnerable) narcissism (Barry & Kauten, 2014; Barry & Wallace, 2010). This study sought to replicate previous findings that pathological narcissism is linked to self-reported prosocial behavior (Kauten & Barry, 2014) and further investigated the relation of self-reported narcissism with self-, parent-, and peer-reported prosocial behavior in a sample of 212 adolescents (M age = 16.8 years, SD …

Refinement Of The Attitudes Toward Anger Management Scale, David Jerome Boudreaux

Dissertations

Identifying and addressing potential problems with anger before they result in adverse consequences could be beneficial in improving quality of life and minimizing the disruptive effects of anger on one’s social environment. Excessive anger or anger which is expressed in maladaptive ways present particular challenges for college students due to their developmental stage, stressors, and environmental demands. Unfortunately, too few college students utilize available mental health resources. Individuals with problem anger are influenced by unique factors that affect help seeking decisions. A better understanding of these factors could facilitate outreach and improve service utilization. This study continued the development of …

An Assessment Of Number Representation In The Small-Eared Bushbaby (Otolemur Garnettii), Tiffany Aycia Woodard Baker

Master's Theses

In an effort to explain the underlying mechanisms of number representation, both the object-file and the approximate number system have been proposed. Despite the recognition in animals, both nonhuman and human, it remains unclear how numbers are represented cognitively or what system is employed. Furthermore, primate numerosity research has been almost exclusively conducted within haplorhine species (monkeys and apes). Within the strepsirhines (lemurs, lorises, and galagos), it has only been investigated in 15 diurnal and cathermal Malagasy primate species. No study to date has looked at this ability in either African strepsirhines or nocturnal primates. To examine the extent of …

Establishing A Link Between Personality And Social Rank In A Group Of Bottlenose Dolphins (Tursiops Truncatus), Erin Elizabeth Frick

Master's Theses

Bottlenose dolphins (Tursiops truncatus) have been documented to possess personality traits that remain consistent over time (Highfill & Kuczaj, 2007) and across contexts (Kuczaj, Highfill, & Byerly, 2012). Such individual differences are thought to play an important role in various social contexts such as hierarchical dominance (Highfill & Kuczaj, 2010). The present study investigated the relationship between personality and social rank within a captive group of bottlenose dolphins housed at the Roatan Institute for Marine Science (RIMS). Social rank was established using questionnaires distributed to the RIMS experienced staff. Personality traits were derived from behavioral coding using context-specific …

Socio-Emotional Development In Children With Autism Spectrum Disorder, Christiana K. Whitley

Honors Theses

The purpose of the present study was to determine which lesson from a social skills program would result in the greatest improvement in duration of social interaction for children with a diagnosis of Autism Spectrum Disorder (ASD) between the ages of five and fifteen. The Superheroes Social Skills Program (Jensen et al., 2011) includes lesson plans that focus directly on helping children with ASD develop communication skills in group settings. The data indicate that one specific lesson, Participation and Joining In, was responsible for the largest mean increase in duration of social interactions of participants. Social skills lessons were introduced …

Pictorial Race Activiation In Priming Measures, Elena V. Stepanova, Michael J. Strube, Laura E. Clote, Daniel Limes

Faculty Publications

This review explores characteristics of facial primes employed in priming studies of racial prejudice and stereotyping. It addresses the role of perceptual, cue-based processing of visual stimuli characteristics in altering racial typicality, and the effects of different moderators. The authors document the nature of variability in primes and moderators used in priming studies (N = 96) up to 2009. Methodological and conceptual implications are discussed, along with gaps in the field. Better control over facial primes employed, more accuracy in reporting and open access to procedural information are suggested in an effort to improve the state of racial priming …

Getting At The Source Of Distinctive Encoding Effects In The Drm Paradigm: Evidence From Signal-Detection Measures And Source Judgments, Glen E. Bodner, Mark Huff, Raymond W. Lamontagne, Tanjeem Azad

Faculty Publications

Studying Deese–Roediger–McDermott (DRM) lists using a distinctive encoding task can reduce the DRM false memory illusion. Reductions for both distinctively encoded lists and non-distinctively encoded lists in a within-group design have been ascribed to use of a distinctiveness heuristic by which participants monitor their memories at test for distinctive-task details. Alternatively, participants might simply set a more conservative response criterion, which would be exceeded by distinctive list items more often than all other test items, including the critical non-studied items. To evaluate these alternatives, we compared a within-group who studied 5 lists by reading, 5 by anagram generation, and 5 …

The Development Of White Asian Categorization: Contributions From Skin Color And Other Physiognomic Cues, Yarrow Dunham, Ron Dotsch, Amelia R. Clark, Elena V. Stepanova

Faculty Publications

We examined the development of racial categorizations of faces spanning the European–East Asian (“White–Asian”) categorical continuum in children between the ages of four and nine as well as adults. We employed a stimulus set that independently varied skin color and other aspects of facial physiognomy, allowing the contribution of each to be assessed independently and in interaction with each other. Results demonstrated substantial development across this age range in children’s ability to draw on both sorts of cue, with over twice as much variance explained by stimulus variation in adults than children. Nonetheless, children were clearly sensitive to both skin …
