Open Access Theses

Wearable fitness technology is advancing in its capabilities. Every new sensor collects new health data, and it becomes important to study how effectively this data can be utilized to help people lead healthier lives. The American Psychological Association found that Americans live with stress levels higher than what is considered healthy. Poorly managed stress can lead to burnout, which leads to unproductive workers. Burnout is known to cost businesses considerable money. The goal of this research study was to determine if burnout could be reduced through the use of a consumer wearable device along with smartphone apps that alerted wearers …

Dopamine D1 Receptor Activity In The Basolateral Amygdala Is Important For Mediating Fear, Reward And Safety Discrimination Learning, Ka Ho Ng

Open Access Theses

Post traumatic stress disorder (PTSD) patients frequently show impairment in safety learning (Jovanovic, Kazama, Bachevalier, & Davis, 2012). Since the amygdala is known to be critical for emotional processing(Wassum & Izquierdo, 2015) and dopamine signaling in the amygdala is important for mediating both fear and reward learning, current experiments examined the role of dopamine signaling in the BLA in mediating both safety learning and reward seeking. We manipulated dopamine D1 receptor activity with a D1 receptor agonist (SKF 38393) or D1 receptor antagonist (SCH23390) either systemically or infused directly into the BLA 20 minutes prior to training rats in a …

Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers

Open Access Theses

Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting that these …

Experimental Evaluation Of An Ipad-Based Augmentative And Alternative Communication Program For Early Elementary Children With Severe, Non-Verbal Autism, Ariana Azzato

Open Access Theses

The purpose of this study was to evaluate the efficacy of a treatment package including a modified protocol of the Picture Exchange Communication System (PECS) implemented via an autism-specific iPad application. A multiple probe design (Horner & Baer, 1978) was replicated across four individuals with severe, non-verbal autism to investigate effects on requesting skills, natural speech production, and social-communicative behaviors. Results suggest beneficial effects, if implemented with high fidelity. The largest effects were on the participants’ requesting skills. All four participants were able to consistently request for desired items by activating the tablet device, and this skill was maintained after …

Seeking Certainty: Are People Who Are Experiencing Relational Doubt More Sensitive To Relationship Cues?, Christine Ann Daly

Open Access Theses

Experiencing uncertainty in one’s relationship is likely an aversive experience and a motivating factor in restoring confidence about where things stand. Thus, uncertain partners may place more weight on positive and negative interactions with their partner as they seek greater confidence in their evaluation of their relationship. The present research examined how partners responded to two different types of relationship information: a past relationship experience (Study 1, N= 154) and false feedback about its quality (Study 2, N = 154). Results suggest that while partners appear to place significance on positive information, regardless of their uncertainty, whether or not …

Relationship Quality, Engagement, Hope, Self-Worth, And Health-Risk Behaviors In A Physical Activity-Based Positive Youth Development Program, Shaina Cole Riciputi

Open Access Theses

Physical activity-based positive youth development (PYD) programs have the potential to promote positive psychosocial and personal growth (Fraser-Thomas, Côté, & Deacon, 2005) and reduce health risk behaviors in youth (Tebes et al., 2007). Engagement, a motivationally-oriented construct representing the subjective quality of youths’ connection to a program (Skinner, Kindermann, Connell, & Wellborn, 2009), may help promote the positive outcomes associated with PYD participation. Based on competence motivation theory (Harter, 2012), program staff may affect engagement by providing instructional feedback related to program activities, and by fostering the interpersonal climate within the program. This study examined whether youths’ perceptions of their …

Impact Of Peer Relationship And Exposure To Violence On Posttraumatic Stress For Children At Risk For Maltreatment, Aura Ankita Mishra

Open Access Theses

Post-traumatic Stress (PTS) symptomology includes ruminating thoughts and feelings around trauma, inability to feel and express emotions, and avoidance of things related to the traumatic event (American Psychiatric Association, 2000). Children and youth exposed to child maltreatment (abuse and neglect) are at higher risk of experiencing PTS. Extra-familial support, including peer support can reduce post-traumatic stress among youth (Pina et al., 2008). In the present study, Witnessing, Victimization, and Both Witnessing and Victimization due to Exposure to In-Home Violence and Peer Relationship Quality are evaluated as to their relative impact on PTS for children at risk for child maltreatment. Peer …

Zephyr: A Social Psychology-Based Mobile Application For Long-Distance Romantic Partners, Dhiraj Bodicherla

Open Access Theses

Long-distance romantic relationships have become quite common nowadays. With CMC tools advancing day-by-day, their usage among LDRs is proliferating rapidly. Attachment-related anxiety and avoidance can block the ability to enjoy happy relationships. During such situations, remembering happy past moments can be comforting. In this study a mobile chat application that enables LDR couples to reminisce about happy moments was developed. This study primarily focuses on evaluating the usability of this mobile application using survey-based methods. System Usability Scale was considered to discuss the outcome of the study. The overall results provide useful recommendations for further improvements in the design of …

Regulating Belongingness Needs: Regulatory Focus And Responses To Social Exclusion, Katherine E. Adams

Open Access Theses

The current project examined the effect of social exclusion on regulatory focus motivations (promotion and prevention focus). Building on previous work, I posited that whether exclusion activates a more promotion or prevention focus depends on the person’s initial standing with the group (i.e., initial member vs. non-member). Additionally, I hypothesized that regulatory focus motivations should influence excluded individuals’ subsequent social reconnection efforts. In two studies, participants were socially excluded after either being included or not as an initial member of the excluding group; in a first study, participants also had the opportunity to reconnect with a new social partner. …

Quit Playing With Your Watch: Perceptions Of Smartwatch Use, Christopher M. Gaeta

Open Access Theses

This study identified perceptions and social norms that may affect smartwatch adoption. Interviews were conducted to identify perceptions of smartwatch use and norms that might affect those perceptions.

Smartwatch use was found to activate norms associated with wristwatch use – specifically, smartwatch users’ peers took offense to the users looking at their wristwatches. This study also found that norms prevent the use of smartwatches’ voice controls in public and various perceptions of smartwatch use and ownership.

Why Are Some Aggressive Adolescents Popular: Subgroups Of Chinese Aggressive Youth, Li Niu

Open Access Theses

This study examined the heterogeneity of Chinese aggressive adolescents to assess why some aggressive youths are popular and others are not. The sample included 1548 adolescents from eighth and eleventh grade in China and data were obtained from self-reports, teacher reports, and peer assessments. Results from a subgroup analysis in which aggressive youths were classified into high, average, and low popularity subgroups and a k-means cluster analysis indicated that there were two heterogeneous subgroups of aggressive youths who exhibited distinct behavioral profiles. Popular aggressive youths differed from less popular aggressive youths in their higher levels of aggression, prosocial behavior, …

Untangling The Relationship Between Narcissistic Traits And Behavioral Aggression Using A Ffm Framework, Colin Edward Vize

Open Access Theses

Recent work on the construct of narcissism has identified two distinct subtypes: grandiose and vulnerable narcissism. The two variants share an antagonistic core, but differ from one another in traits related to neuroticism and extraversion. We sought to explore how the differences between the subtypes may manifest in relation to behavioral aggression in the laboratory following provocation as well as in relation to a variety of self-report measures of aggression. In the case of behavioral aggression following provocation, our results showed a three-way interaction between gender, threat condition, and vulnerable narcissism such that males who reported higher levels of vulnerable …

Disability Visibility And Stigma Threat: Effects On The Performance, Stress, And Self-Control Of Disabled Workers, William Brice

Open Access Theses

Having a stigmatized disability is a depleting experience. For those with a disability, there are many factors that contribute to potential performance decrements in any given situation. Visibility of the disability, and the stigma connected to the disability are two such factors—which I argue based on research on motivation, regulation, and stress, contributes to the regulatory depletion experienced by disabled individuals. I conducted an experimental study where participants took part in a workplace simulation. Participants were given an artificially simulated disability and both the visibility of the disability and the stigmatizing nature of the disability were manipulated. I found a …

Enhancing Travel Experience With The Combination Of Information Visualization, Situation Awareness, And Distributed Cognition, Weiran Lei

Open Access Theses

With the new forms of travel introduced by new technologies of transportation and communication, a satisfied travel experience could be affected by various factors before and during a trip. Especially for road trips, traveling by car provides freedom on time control while leading to more possibilities of rescheduling initial plans made under time constraints. When overwhelmed with the need for changed travel context to avoid unexpected events that will require a serious change of initial plans, travelers need to find and access helpful contextual information quickly. This is a context-related decision making process that requires amplifying human situation awareness and …

Envy has been regarded as a complex emotion which can produce both positive and negative outcomes for consumers. This study explored the subjective experience of customer envy at service encounters in order to better understand how customers respond to unflattering comparisons with an envied customer. A questionnaire was designed to measure the cognitive appraisals, emotional responses, and consequences of customer envy. Study participants were also asked to share their envy incidents in the survey. A sample of 300 participants was collected and used for analysis. The findings illustrate that distinctively different patterns of cognitive appraisals such as preferential treatment, are …

The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud

Open Access Theses

Attention-deficit/hyperactivity disorder (ADHD) is the most diagnosed behavioral disorder in children. It affects around 5% of children worldwide and 11% of children in the United States, with rates increasing. Pharmaceutical treatments, such as amphetamines and methylphenidates, are not effective for everyone and are known to have unwanted side effects. While the etiology of the disorder is not yet fully understood, there are clear genetic and environmental components. Nutritional insufficiencies have recently become a popular environmental risk factor under investigation. Essential fatty acids (EFA), omega-3 polyunsaturated fatty acids (PUFA) in particular, are needed for proper brain development and function. Our lab …

Open Access Theses

ABSTRACT Harris, Rachel C. M. S., Purdue University, December 2014. Postural Control in Infants at Low and High Risk for Autism Spectrum Disorder. Major Professor: Laura J. Claxton. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder more commonly known for deficits in social and communication skills. More recently, aspects of motor development have been shown to be delayed in children with ASD, including deficits in their postural control abilities. Children with ASD have difficulty integrating information from their sensory systems to help control their balance. Infants at risk for ASD and infants who are later diagnosed with ASD have delays …

Capacity-Related Driver Behavior On Modern Roundabouts Built On High-Speed Roads, Shaikh Ahmad

Open Access Theses

The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of drivers as represented by critical headway (critical gap) and follow-up headway (follow-up time). The effects of heavy vehicles (single-unit truck, bus, and semi-trailer) and area type (rural or urban) on roundabout capacity were investigated by comparing the critical headways for roundabouts located on high-speed and low-speed roads. The effects of nighttime conditions (in the presence of street lighting) were also considered. Data were collected using the Purdue …

Optimization Of Switch Virtual Keyboard By Using Computational Modelling, Xiao Zhang

Open Access Theses

In this thesis, I first reviewed some keyboard technologies used by people with motor difficulties, and described design elements that influence efficiency. I cast the design of a switch keyboard as an optimization problem, and arrangement of keys on such a keyboard as a Mixed Integer Programming problem. One significant variable in the MIP problem, the error rate, is related to several other variables. I treated modeling of the error rate as a parameter estimation problem, and used a data mining method. I designed HCI experiments to gather data for parameter estimation, using Bayesian logistic regression model. The empirical data …

Is Maternal Touch Used Referentially?, Rana Abu-Zhaya

Open Access Theses

Early social interactions are highly multimodal and include a wealth of cues (e.g., speech, facial expressions, motion, gestures and touch). Infant-directed speech (IDS) by itself may aid in language development. Touch by itself has been also shown to play an important role in dyadic interactions affecting both the infant and the caregiver. However, little is known about the impact of the combination of these two modes of communication on infant language development. In this thesis, I hypothesize that caregiver touch is provided in synchrony with speech, providing the language-learning infant with cues that may not only help her to find …

The Effect Of Ostracism By Strangers On Romantic Relationship Evaluations, Maayan Dvir

Open Access Theses

One behavioral consequence of ostracism is to seek and strengthen connections with others. The current research tests whether a brief episode of ostracism by strangers strengthens targeted individuals' perceptions of their romantic relationship and increases their desire to be closer to their partner. In Study 1a and Study 1b, participants were either included or ostracized by strangers in a Cyberball game, and then completed relationship evaluation measures. Interactions of ostracism and gender emerged, suggesting that as hypothesized, ostracized women tended to evaluate their relationships more positively than included women. However, men who were ostracized tended to evaluate their relationships less …

Preschoolers’ Physical, Social, And Engineering Play Behaviors: Differences In Gender And Play Environment, Zachary S. Gold

Open Access Theses

This study explored gender differences in the occurrence of 66 preschoolers' (ages 3-to-5; 29 girls, 37 boys) physical, social, and "engineering thinking play" behaviors across three play environments: the traditional playground, the dramatic play area, and an environment in which children played with large, manipulable, loose parts. Previous research has indicated that young children are not engaging in enough physical play to maintain healthy lifestyles. Play may also have benefits for social competency and cognitive development. Observations of children's engagement with a new and engaging play material, Imagination Playground TM blocks, which are designed to foster imaginative and creative constructive …

Relations Between Teachers’ Motivation And Students’ Motivation: A Self-Determination Theory Perspective, Inok Ahn

Open Access Theses

There is little research that examines impact teachers' motivation on students' motivation due to sparse attention to teachers' motivation. The primary purpose of this study was to investigate the relations between teachers' motivation and students' motivation using self-determination theory. Participants were 697 5th and 6th students and 35 of their teachers in Seoul, South Korea. Students completed the questionnaires for motivation, basic psychological needs, and perceptions of teacher's instructional styles. Teachers also answered questionnaires about their own motivation. Multiple regression analyses were used to analyze the data. Teaching experience was controlled for throughout the analysis process due to its significant …

Attachment Representations And Mother-Child Dialogue, Baiba Barene

Open Access Theses

With the emerging linguistic competencies of the child, dialogue becomes a regular part of mother-child everyday interactions, and may serve as one of the mechanisms of transmission of attachment in early and middle childhood. The goal of this study was to investigate the hypothesis about the co-constructive nature of children's knowledge of secure base script. Formation of the secure base script is a result of child-caregiver interactions that have been consolidated into a unit of knowledge available for use in attachment related situations. Individual attachment narratives and mother-child co-constructed narratives were collected from 86 mother-child dyads when children were 3.7 …

Ostracism And Interest In Extreme Groups, Andrew H. Hales

Open Access Theses

Drawing from the temporal need-threat theory of ostracism (Williams, 2009), and uncertainty-identity theory (Hogg, 2007), I tested the hypothesis that ostracism increases interest in extreme groups. In a cross-sectional survey, Study 1 showed that chronic ostracism positively predicts interest in the Westboro Baptist Church, Mormonism, Scientology, and Alcoholics Anonymous. Study 2 established causal direction; relative to included participants, ostracized participants expressed greater willingness to attend a meeting of an extreme group following a recruitment attempt. Expressing a desire to attend meetings facilitated recovery of basic need satisfaction. Ostracism also induced self-uncertainty, but this did not mediate the effect. In an …

Gap Between Hospitality Employers' Demands And Hospitality Students' Perceptions Regarding Entry-Level Managers' Requirements In The United States, Yijun Huang

Open Access Theses

This study aims to identify the gap between recruiters and students regarding what knowledge, skills and abilities are most needed for graduates to secure entry-level managers in the hospitality industry. Previous literature used different approaches to attain a similar idea that students and recruiters do have different opinions, especially for those intrinsic or person-related characteristics. The researcher borrowed statements from different researchers and added two statements to make up the missing part of previous research and then combined, split and revised these statements to see whether students' thinking matched the industry's thinking. The results showed that recruiters generally ranked these …

Anticipatory And Reactive Responses To Chocolate Restriction In Frequent Chocolate Consumers, Chelsey L. Keeler

Open Access Theses

Many individuals have difficulty adhering to a weight loss diet. One possible explanation could be that dietary restriction paradoxically contributes to overconsumption. The objective of this study was to examine ingestive behavior under a forced chocolate restriction, with a focus on the anticipatory restriction period and the post-restriction period in frequent chocolate consumers. Fifty-six male (N=18) and female (N=38) high chocolate consumers with high or low cognitive disinhibition aged 27.70 ± 11.09 years with a mean BMI of 25.68± 5.92 kg/m2 participated. Chocolate snacks were provided for the first, second, and sixth week of the study to establish baseline, pre-restriction …

The Effect Of Color On Emotions In Animated Films, Andrew Kennedy

Open Access Theses

Lighting color in animated films is usually chosen very carefully in order to portray a specific mood or emotion. Artists follow conventional techniques with color choices with the intention to create a greater emotional response in the viewer. This study examined the relationship between color variations in videos and emotional arousal as indicated by physiological response. Subjects wore a galvanic skin response (GSR) sensor and watched two different videos: one portraying love and one portraying sadness. The videos were watched multiple times, each with variations in the lighting color. No significant effects on emotion for either hue or saturation were …

Coping With Emotions During Reintegration: An Evaluation Of Service Members' Psychological Health, Christina Marie Marini

Open Access Theses

Upon returning home from deployment, service members are likely coping with strong emotions related to deployment stressors. In addition, service members and their intimate partners may be tasked with emotionally reconnecting with one another after an extended period of separation. Reintegration is therefore a critical, transitory time to evaluate associations between emotional coping strategies utilized by service members and their partners as predictors of service members' well-being. Previous research has indicated that service members' expression of emotions is positively related to their well-being post-deployment, whereas their avoidance is negatively related. These relationships were reevaluated in the current study. The current …
