Recognition Training For Faces Across Age Gaps, William Blake Erickson Aug 2016

Recognition Training For Faces Across Age Gaps, William Blake Erickson

Graduate Theses and Dissertations

Face recognition is a problem that has theoretical and applied value. However, the fact of facial aging is rarely addressed in research and unmentioned in the major theories of face recognition. Facial aging also has ramifications for missing persons and fugitive cases, confounding attempts by law enforcement to recover these people whose last known images are years or decades out of date. This dissertation reports three studies aimed at measuring baseline age-gap recognition ability and testing various training regimens designed to increase accuracy rates for this unique kind of recognition task.


Impulsivity, Rejection Sensitivity, And Reactions To Stressors In Borderline Personality Disorder, Kathy R. Berenson, Wesley Ellen Gregory, Erin Glaser, Aliza Romirowsky, Eshkol Rafaeli, Xiao Yang, Geraldine Downey Aug 2016

Impulsivity, Rejection Sensitivity, And Reactions To Stressors In Borderline Personality Disorder, Kathy R. Berenson, Wesley Ellen Gregory, Erin Glaser, Aliza Romirowsky, Eshkol Rafaeli, Xiao Yang, Geraldine Downey

Psychology Faculty Publications

This research investigated baseline impulsivity, rejection sensitivity, and reactions to stressors in individuals with borderline personality disorder compared to healthy individuals and those with avoidant personality disorder . The borderline group showed greater impulsivity than the avoidant and healthy groups both in a delay-discounting task with real monetary rewards and in self-reported reactions to stressors; moreover, these findings could not be explained by co-occurring substance use disorders. Distress reactions to stressors were equally elevated in both personality disorder groups (relative to the healthy group). The borderline and avoidant groups also reported more maladaptive reactions to a stressor of an interpersonal …


An Assessment Of Number Representation In The Small-Eared Bushbaby (Otolemur Garnettii), Tiffany Aycia Woodard Baker Aug 2016

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 …


Socio-Emotional Development In Children With Autism Spectrum Disorder, Christiana K. Whitley Aug 2016

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 …


Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills Aug 2016

Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills

Department of Psychology: Dissertations, Theses, and Student Research

The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …


The Effect Of Auditory Stimulation On Sleep Disruption In West Indian Manatee (Trichechus Manatus Latirostris), Natalija Lace Aug 2016

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 …


Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist Aug 2016

Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist

Dissertations

Recent escalation in the popularity of recreational synthetic cathinone (“bath salts”) use has prompted numerous scientific investigations of the neurochemical and behavioral effects of 3,4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC), two of the more common chemical constituents of these illicit “bath salts”. Previous neurochemical and electrophysiological studies have revealed that MDPV functions as a blocker, and 4-MMC as a substrate, at monoamine transporters, and both produce transient increases in extracellular monoamines. In addition, previous research has demonstrated that MDPV and 4-MMC support self-administration in nonhuman experimental subjects, and their rewarding effects are observed when paired with contextual cues in nonhuman models …


Establishing A Link Between Personality And Social Rank In A Group Of Bottlenose Dolphins (Tursiops Truncatus), Erin Elizabeth Frick Aug 2016

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 …


The Tootling Intervention With Classdojo: Effects On Classwide Disruptive Behavior And Academically Engaged Behavior In An Upper Elementary School Setting, Melissa Mchugh Dillon Aug 2016

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 …


The Influence Of Discrete Emotional States On Preferential Choice, Andrea M. Cataldo Jul 2016

The Influence Of Discrete Emotional States On Preferential Choice, Andrea M. Cataldo

Masters Theses

Past research has shown that emotion affects preferential choice outcomes. The goal of the present study was to further research on emotion and preferential choice by using mathematical modeling to investigate the effects of specific dimensions of emotion on the underlying mechanisms of preferential choice. Specifically, we aimed to determine whether the concurrent effects of positive-negative valence and situational certainty on attention and information accumulation threshold, respectively, would influence the magnitude of the similarity effect, a robust phenomenon in preferential choice. Participants first underwent either an Anger (negative and certain), Fear (negative and uncertain), or no (Control) emotion manipulation. All …


Human-Robot Interaction: Proximity And Speed—Slowly Back Away From The Robot!, Keith R. Macarthur, Kimberly Stowers, Peter A. Hancock Jul 2016

Human-Robot Interaction: Proximity And Speed—Slowly Back Away From The Robot!, Keith R. Macarthur, Kimberly Stowers, Peter A. Hancock

Keith Reid MacArthur

This experiment was designed to evaluate the effects of proximity and speed of approach on trust in human-robot interaction (HRI). The experimental design used a 2 (Speed) × 2 (Proximity) mixed factorial design and trust levels were measured by self-report on the Human Robot Trust Scale and the Trust in Automation Scale. Data analyses indicate proximity [F(2, 146) = 6.842, p < 0.01, partial ŋ 2 = 0.086] and speed of approach [F(2, 146) = 2.885, p = 0.059, partial ŋ 2 = 0.038] are significant factors contributing to changes in trust levels.

Understanding Posttraumatic Stress And Academic Achievement: Exploring Attentional Control, Self-Efficacy, And Coping Among College Students, Ashley M. Cantrell Jul 2016

Understanding Posttraumatic Stress And Academic Achievement: Exploring Attentional Control, Self-Efficacy, And Coping Among College Students, Ashley M. Cantrell

Masters Theses & Specialist Projects

The present study examined differences in attentional control, attentional control self-efficacy, and coping as self-regulatory mechanisms among students with varying grade point averages (GPA) who experience posttraumatic stress symptoms (PTSS). Subjects included 58 college students from one large comprehensive university in the Mid-South who met the criteria for diagnosis of PTSS based on the Impact of Event Scale-Revised (IES-R). Three groups were created based on college GPA and graduation requirements at the university (at-risk for graduation, on-track for graduation, and ontrack for graduating with honors). Participants completed a survey that included demographics and measures of PTSS, attentional control, attentional control …


Self-Regulation In Preschoolers: Validity Of Hot And Cool Tasks As Predictive Measures Of Academic And Socio-Emotional Aspects Of School Readiness, Berenice Anaya Jul 2016

Self-Regulation In Preschoolers: Validity Of Hot And Cool Tasks As Predictive Measures Of Academic And Socio-Emotional Aspects Of School Readiness, Berenice Anaya

Masters Theses & Specialist Projects

Extensive research on the development of self-regulation has demonstrated that better executive functioning and effortful control during the preschool years are associated with greater kindergarten and early school achievement. Recent findings suggest that self-regulation tasks differ in their assessment of “hot” and “cool” regulation, how these processes map onto effortful control and executive functioning, and may predict school readiness. However, only a few studies have examined the validity of hot and cool regulation tasks (Allan & Lonigan, 2014; Di Norcia, Pecora, Bombi, Baumgartner, & Laghi, 2015; Willoughby, Kupersmidt, Voegler-Lee, & Bryant, 2011), and how they predict socio-emotional competence (Di Norcia …


Effects Of Age, Task Type, And Information Load On Discrimination Learning, Morgan E. Brown Jul 2016

Effects Of Age, Task Type, And Information Load On Discrimination Learning, Morgan E. Brown

Masters Theses & Specialist Projects

The feature positive effect (FPE) is a phenomenon in discrimination learning by which learning occurs more quickly when the presence (Feature positive; FP), rather than absence (Feature negative; FN) of a stimulus indicates a response should be made. Although the FPE has been extensively corroborated, a reversal, or feature negative effect (FNE), has been found when a target stimulus comes from a smaller set of stimuli (Fiedler, Eckert, & Poysiak, 1988). Age differences in FP and FN learning indicate that older adults perform more poorly than young adults on both FP and FN tasks, and are likely related to decline …


The Development Of Attention To Dynamic Facial Emotions, Alison Heck, Alyson Hock, Hannah White, Rachel Jubran, Ramesh Bhatt Jul 2016

The Development Of Attention To Dynamic Facial Emotions, Alison Heck, Alyson Hock, Hannah White, Rachel Jubran, Ramesh Bhatt

Psychology Faculty Works

Appropriate processing of emotions is paramount for successful social functioning. Adults’ enhanced attention to negative emotions such as fear is thought to be a critical aspect of this adaptive functioning. Prior studies indicate that increased attention to fear relative to positive or neutral emotions begins at around 7 months of age, and it has been suggested that this negativity bias is related to self-locomotion. However, these studies mostly used static faces, potentially limiting information available to the infants. In the current study, 3.5-month-olds (n = 24) and 5-month-olds (n = 24) were exposed to dynamic faces expressing fear, happy, or …


Buffering The Associations Between Negative Mood States And The Incentive Salience Of Alcohol: A Brief Mindfulness Induction, Adrian J. Bravo Jul 2016

Buffering The Associations Between Negative Mood States And The Incentive Salience Of Alcohol: A Brief Mindfulness Induction, Adrian J. Bravo

Psychology Theses & Dissertations

The present study examined drinking to cope (DTC) motives and state mindfulness (via a brief mindfulness induction) as two distinct factors that may enhance (DTC) and reduce (state mindfulness) the association between negative mood states (i.e., sadness and anxiety) and the incentive salience of alcohol (i.e., subjective alcohol craving and attentional bias for alcohol-related cues) among college student drinkers. Participants were 207 undergraduate students from a large, southeastern university in the United States that consumed at least one drink per typical week in the previous month. The majority of participants identified as being either White, non-Hispanic (n = 81; 39.1%), …


Relationship Investment And Unwanted Pursuit: An Experimental Study, Phoebe Tabb Hitson Jul 2016

Relationship Investment And Unwanted Pursuit: An Experimental Study, Phoebe Tabb Hitson

Psychology Theses & Dissertations

A significant positive correlation exists between relationship investment and the perpetration of unwanted pursuit among previous romantic partners. However, no experimental research has been conducted to enhance researchers’ knowledge of this phenomenon. This study contributed to the literature on unwanted pursuit by making investment an experimentally manipulated variable. Specifically, I employed fictional relationship scenarios with varying levels of investment to assess experimentally the impact of investment on an individual’s willingness to engage in unwanted pursuit after a breakup. It was hypothesized that higher investment would increase participants’ tendency to engage in unwanted pursuit. In addition, participants’ past perpetration of unwanted …


Measuring Team Collaboration And Effects Of Target Guidance In A Visual Search Task, Christopher Morley Jul 2016

Measuring Team Collaboration And Effects Of Target Guidance In A Visual Search Task, Christopher Morley

Psychology Theses & Dissertations

Many professional tasks, including military operations and medical operations, involve a team of operators searching for a target on a common visual display. Previous works on collaborative visual search employed analysis of mean response time (RT) and error rates, which may not offer direct measurement of the capacity of a team nor changes in performance across task time. Workload capacity, indexed by the capacity coefficient, C(t), measures performance efficiency for cognitive systems with multiple and concurrent information-processing channels (Townsend & Nozawa, 1995). The current study applied a workload capacity analysis to quantify performance efficiency of pairs of participants in a …


Acculturation And Enculturation, Perception Of Depressive Symptoms, And Help-Seeking Behaviors Among Korean Americans, Kristoffer Park Jul 2016

Acculturation And Enculturation, Perception Of Depressive Symptoms, And Help-Seeking Behaviors Among Korean Americans, Kristoffer Park

Psychology Theses & Dissertations

The literature suggests that acculturation, enculturation, and the perception of mental health symptoms are some of the factors that explain help-seeking behaviors in Asian Americans. While there has been previous research addressing these concerns for Asian Americans as a unified ethnic group, few studies have examined these factors to explain help-seeking behaviors specifically in Korean Americans. 107 Korean Americans were recruited from Korean American churches in a large metropolitan city in the southeast region. Participants completed an online questionnaire, which included instruments assessing acculturation (AVS-R) and enculturation (EAVS-AA-R) levels as well as their perception of how problematic depressive symptoms were …


Effects Of Visibility And Alarm Modality On Workload, Trust In Automation, Situation Awareness, And Driver Performance, Smruti J. Shah Jul 2016

Effects Of Visibility And Alarm Modality On Workload, Trust In Automation, Situation Awareness, And Driver Performance, Smruti J. Shah

Psychology Theses & Dissertations

Driving demands sustained driver attention. This attentional demand increases with decreasing field visibility. In the past researchers have explored and investigated how collision avoidance warning systems (CAWS) help improve driving performance. The goal of the present study is to determine whether auditory or tactile CAWS have a greater effect on driver performance, perceived workload, system trust, and situation awareness (SA). Sixty-three undergraduate students from Old Dominion University participated in this study. Participants were asked to complete two simulated driving sessions along with Motion Sickness Susceptibility Questionnaire, Background Information Questionnaire, Trust Questionnaire, NASA Task Load Index Questionnaire, Situation Awareness Rating Technique …

The Multidimensional Mortality Awareness Measure & Model (Mmamm): Development And Validation Of A New Self-Report Questionnaire & Psychological Framework, Mark R. Mcdermott, Kathryn Lafreniere Jun 2016

The Multidimensional Mortality Awareness Measure & Model (Mmamm): Development And Validation Of A New Self-Report Questionnaire & Psychological Framework, Mark R. Mcdermott, Kathryn Lafreniere

Kathryn Lafreniere

For each of eight literature-identified conceptual dimensions of mortality awareness, questionnaire items were generated, producing 89 in all. 359 participants responded to these items and to questionnaires measuring health attitudes, risk-taking, rebelliousness and demographic variables. Multivariate correlational analyses investigated the underlying structure of the item pool and the construct validity as well as the reliability of the emergent empirically derived subscales. Five components, rather than eight, were identified. Given the item content of each, the associated mortality awareness subscales were labelled as: legacy, fearfulness, acceptance, disempowerment, and disengagement. Each attained an acceptable level of internal reliability. Relationships with other variables …


Associations Between Social Status Insecurity And Relational Aggression In Chinese Adolescents: Moderations Of Social Cognitive Prosesses, Yunyi Long Jun 2016

Associations Between Social Status Insecurity And Relational Aggression In Chinese Adolescents: Moderations Of Social Cognitive Prosesses, Yunyi Long

College of Science and Health Theses and Dissertations

Adolescents pay close attention to their social status and actively pursue it through certain social behaviors. Previous studies have revealed that when adolescents feel their social standing is unsafe, namely having social status insecurity, they often use relational aggression to cope with it. However, what roles different social cognition processes play on the association between social status insecurity and relational aggression are unclear in the literature. Additionally, given that the relationship between relational victimization and relational aggression has also been observed in the literature, social status insecurity may also exert an important mediating impact on such an association. Nevertheless, few …


The Behavioral Analysis Of Gambling, Benjamin Witts, Anne Macaskill, Mack Costello Jun 2016

The Behavioral Analysis Of Gambling, Benjamin Witts, Anne Macaskill, Mack Costello

International Conference on Gambling & Risk Taking

A behavioral analysis of gambling is unique among the psychologies. A behavioral analysis seeks answers to questions pertaining to the prediction and influence of gambling in terms of the individual gambler, and thus emphasis is placed on well-controlled small-n studies in which findings are generalized to other individuals. Further, the behavioral analysis of gambling is concerned with environmental and historical relations in accounting for current gambling behavior, and less of a reliance is placed on internal and hypothetical causal factors. This symposium explores two data-driven analyses of gambling behavior from a behavioral account of gambling while a third conceptual and …


Psychological Abuse, Mental Health, And Acceptance Of Dating Violence Among Adolescents, Jeff R. Temple, Hye Jeong Choi, Joanna Elmquist, Michael L. Hecht, Michelle Miller-Day, Gregory L. Stuart, Meagan Brem, Caitlin Wolford-Clevenger May 2016

Psychological Abuse, Mental Health, And Acceptance Of Dating Violence Among Adolescents, Jeff R. Temple, Hye Jeong Choi, Joanna Elmquist, Michael L. Hecht, Michelle Miller-Day, Gregory L. Stuart, Meagan Brem, Caitlin Wolford-Clevenger

Communication Faculty Articles and Research

Purpose

Existing literature indicates that acceptance of dating violence is a significant and robust risk factor for psychological dating abuse perpetration. Past work also indicates a significant relationship between psychological dating abuse perpetration and poor mental health. However, no known research has examined the relationship between acceptance of dating violence, perpetration of dating abuse, and mental health. In addition to exploring this complex relationship, the present study examines whether psychological abuse perpetration mediates the relationship between acceptance of dating violence and mental health (i.e., internalizing symptoms of depression, anxiety, and hostility).

Methods

Three waves of longitudinal data were obtained from …


The Effects Of Conspecifics On Dog (Canis Lupus Familiaris) Behavior During Behavioral Rehabilitation Treatments, Breanna Schultz May 2016

The Effects Of Conspecifics On Dog (Canis Lupus Familiaris) Behavior During Behavioral Rehabilitation Treatments, Breanna Schultz

Theses and Dissertations

With high dog euthanasia rates increasing adoption is a significant animal welfare issue that finding methods to treat fearful animals from cruelty cases could help. This study examined the effects of conspecific presence on dogs in behavioral rehabilitation and found significant differences in boldness-fearfulness and solicitation and proximity behaviors.


A Cultural Comparison Of Two Facial Inference Studies, Janine Swiney May 2016

A Cultural Comparison Of Two Facial Inference Studies, Janine Swiney

Symposium Of University Research and Creative Expression (SOURCE)

Two different samples from Pakistan and the United States were asked to infer the emotions and personality traits shown in three facial expressions (angry, sad, happy) of young white females and males in six photographs. The two studies used Amazon.com’s Mechanical Turk (MTurk) to investigate the facial inference process. Each picture was presented for 10 seconds followed by four questions about the individual in the picture. The first question asked participants to identify the emotion shown, from a list of six emotions (anger, disgust, fear, happiness, sadness, surprise). The next three questions consist of condensed sets of the Big Five …


The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry May 2016

The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry

Seton Hall University Dissertations and Theses (ETDs)

The inability to remember events experienced very early in life is referred to as Infantile Amnesia (IA) and has been observed in both humans and animals. Over the years interest in the phenomenon waned, but has recently increased with the discovery of new neurobiological methods to study brain function (e.g., Callaghan, Li & Richardson, 2014). The neurobiological mechanism behind IA has yet to be determined, but several innovative theories have been developed with these new research methods. The neurogenesis hypothesis theorizes that increased neurogenesis during early development disrupts previously established memories. The hippocampus, an area that mediates both the memory …


Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd May 2016

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …
