Processing Of Spatial Information In Social And Non-Social Stimuli By Opioid-Exposed And Non-Exposed Newborns, Alyson J. Hock

Theses and Dissertations--Psychology

The ability to process information from faces is important for effective social functioning. Adults are experts at this function. It has been suggested that the encoding of configural spatial relations among facial features (e.g., the distance between the eyes) contributes to this expertise. I investigated the developmental origin of face processing expertise by studying typically developing newborns’ sensitivity to the distance between the eyes and between the nose and the mouth in face stimuli. Further, I investigated whether prenatal opioid exposure is associated with neonates’ processing of spatial information in social and non-social stimuli. Infants with prenatal opioid-exposure are at …

Sexy, Thin, And White: The Intersection Of Sexualization, Body Type, And Race On Stereotypes About Women And Women's Body Dissatisfaction, Ellen A. Stone

Theses and Dissertations--Psychology

The vast majority of media images present one idealized type of woman: she is thin, sexualized, and White. While research has shown that there are stereotypes associated with sexualized women, research has not addressed whether these stereotypes vary based on other characteristics such as body type and race. The current study aimed to examine the stereotypes associated with women who varied in body size, sexualization, and race. Additionally, the current study examined whether exposure to differing portrayals of women was related to endorsement of gender stereotypes and body dissatisfaction. College-aged students (n = 226, 161 women) rated four traits …

Too Pretty For Homework: The Academic Correlates Of Sexualized Gender Stereotypes Among Adolescent Girls, Andrew A. Nelson

Theses and Dissertations--Psychology

Girls grow up in a culture of ubiquitous female sexualization, and this culture propagates stereotypes that could interfere with their academic outcomes. The current study examined the academic correlates of these sexualized gender stereotypes (SGS) among early adolescent girls. Girls (N = 99) aged 11 to 14 (M_age = 12.4 years, SD = .57 years) completed a survey assessing their academic performance, attitudes, and beliefs. The survey also assessed the degree to which girls believed that boys and girls should act in accordance with these sexualized gender stereotypes. Results indicated that higher endorsement of sexualized gender stereotypes …

Risk Factors For Abuse Of Prescription Stimulants In College Students: A Dissertation, Eric A. Haak

Theses and Dissertations--Psychology

The abuse of prescription stimulants among college students is a growing public health concern. While these substances are often viewed as safe, “smart drugs”, they are associated with a number of maladaptive outcomes, ranging from poorer academic performance to cardiovascular incidents and even death. To date, the majority of research on the abuse of these substances have focused on demographic factors which are not amenable to intervention, such as race, Greek organization status, and class rank. The current study examined family factors, academic stress, and impulsivity as potential risk factors which are amenable to intervention. In a sample of 335 …

Body Part Structure Knowledge In Infancy, Rachel Jubran

Theses and Dissertations--Psychology

Human faces, bodies, and hands convey critical social information (e.g., emotions, goals, and desires). Infants, like adults, are sensitive to such social information. Unlike infants’ knowledge of the structure of the human face and body, not much is known about infants’ knowledge of hands and feet. The current study tested infants for their preference between intact hand images and ones in which the same hands were distorted (i.e., location of at least one finger was altered to distort the typical structure of the hand). Infants at 3.5 months of age had a preference for the reorganized hand image, demonstrating that …

Categorical Perception Of Species In Infancy, Hannah B. White

Theses and Dissertations--Psychology

Although there is a wealth of knowledge on categorization in infancy, there are still many unanswered questions about the nature of category representation in infancy. For example, it is yet unclear whether categories in infancy have well-defined boundaries or what knowledge about species categories young infants have before entering the lab. Using a morphing technique, we linearly altered the proportion of cat versus dog in images and observed how infants reacted to contrasts between pairs of images that either did or did not cross over the categorical boundary. This was done while equating between-category and within-category similarity. Results indicate that …

Attention Deficit Hyperactivity Disorder & Narrative Comprehension Deficits In College Students, Laura E. Vincent

Theses and Dissertations--Psychology

The current study examined if the narrative comprehension deficits that children with ADHD exhibit during childhood and adolescence continue in college students as a function of ADHD symptoms, and if a relationship existed between ADHD symptoms and self-efficacy. Children and adolescence with ADHD have difficulties in several areas of narrative comprehension, including maintaining goal structure, distinguishing important events from unimportant events, and making causal connections. If these deficits persist there also may be a relationship between ADHD symptoms and self-efficacy.

Higher levels of ADHD symptomatology were associated with difficulties recalling story events in the college population. Some findings differed from …

Adolescents' Gender Typicality, Psychological Well-Being, And Experiences With Teasing, Bullying, And Rejection, Jennifer A. Jewell

Theses and Dissertations--Psychology

The current study examined whether adolescents’ gender-based victimization experiences (i.e., teasing, bullying, and rejection) mediated the association between gender typicality and psychological well-being. The current study also investigated whether daily experiences with the three types of gender-based victimization negatively impacted adolescents’ immediate emotional reactions. Participants were 570 seventh and eighth grade students (49.5% boys, 50.5% girls). During four visits over the course of two weeks, participants completed surveys about their own gender typicality, their psychological well-being (i.e., depression, anxiety, self-esteem, and body image), their experiences with gender-based teasing, bullying, and rejection, and their emotional responses to experiencing this victimization. Results …

The Reciprocal Predictive Relationship Between Personality And Risky Behaviors: An 8-Wave Longitudinal Study In Early Adolescents, Elizabeth N. Riley

Theses and Dissertations--Psychology

While the overall stability of personality across the lifespan has been well-documented, there is also evidence of meaningful personality change. This is particularly true when individuals are going through periods of developmental transition. Over time, one sees incremental changes not just in behavior but in basic personality as well. 1,906 early adolescents were assessed for urgency scores, levels of maladaptive behavior engagement (drinking, smoking, and binge eating), and pubertal status every six months for four years. Zero-Inflated Poisson structural equation modeling (SEM) was used to test the model of reciprocal influence between behavior and personality. Across most six-month intervals over …

Parenting Behaviors Of Sleepy Parents: Associations With Emotion Regulation And Stress, Lauren R. Gilbert

Theses and Dissertations--Psychology

Over the last decade, the topic of sleep has garnered a great deal of interest from psychologists, due to the physiological, emotional, and behavioral outcomes associated with its deprivation. However, questions remain to be answered regarding sleep's influence in the day-to-day life of families. The current study examines the importance of sleep deprivation for parents’ parenting behaviors during problem solving discussions with their children; emotion regulation and stress reactivity are examined as mediators of these associations. Participants were 196 families with a child between the ages of 6-11. Parents filled out diaries for 7 days prior to their in-lab visit, …

Korean American Adolescents And Their Mothers: Intergenerational Differences And Their Consequences, Hui Chu

Theses and Dissertations--Psychology

The current study examined the links and mechanisms associated with intergenerational cultural conflict, psychological distress, and the intergenerational differences in acculturation and model minority stereotype (MMS) endorsement for South Korean immigrants. Specifically, Korean American adolescents’ (ages 12-19, M = 15.3, SD = 1.71) and their mothers’ (N = 209 dyads) acculturation difference and MMS endorsement difference were measured and analyzed as predictors of intergenerational cultural conflict and psychological distress for adolescents. Furthermore, the study analyzed intergenerational cultural conflict as a mediator in the acculturation gap-distress and the MMS endorsement-distress paths. Results indicated that when mothers and their adolescents differed …

Temperament And Personality Traits As Predictors Of Preschool Odd Symptoms, Longitudinal Course, And Impairment, Brittany L. Zastrow

Theses and Dissertations--Psychology

Oppositional Defiant Disorder (ODD) is commonly conceptualized as a disorder of negative affect and low effortful control. Currently, it is unclear whether temperament and personality traits associated with negative affect and effortful control can be useful assessment tools for identifying ODD early during development. This study examined the relationship between temperament and personality traits and ODD in a clinical sample of preschoolers. Results suggest that, at this age, temperament and personality traits of negative affect and neuroticism and effortful control and conscientiousness/agreeableness are not associated with one another. High negative affect, low conscientiousness, and low agreeableness were all specifically …

Eating Disorder Onset In Young Girls: A Longitudinal Trajectory Analysis, Carolyn M. Pearson

Theses and Dissertations--Psychology

To investigate whether there are different patterns of development for binge eating and purging behavior among pre-adolescent and early adolescent girls, I conducted trajectory analyses of those behaviors in 938 girls across eight waves of data from the spring of 5^th grade (the last year of elementary school) through the spring of 9^th grade (the first year of high school). Analyses revealed four separate developmental trajectories for binge eating behavior (labeled none, increasing, decreasing, and high steady) and three separate developmental trajectories for purging behavior (labeled none, dabble, and increasing). Fifth grade scores on risk factors that were …

Facial And Body Emotion Recognition In Infancy, Leah Oberst

Theses and Dissertations--Psychology

Adults are experts at assessing emotions, an ability essential for appropriate social interaction. The present study, investigated this ability’s development, examining infants’ matching of facial and body emotional information.

In Experiment 1, 18 6.5-month-olds were familiarized to angry or happy bodies or faces. Those familiarized to bodies were tested with familiar and novel emotional faces. Those habituated to faces were tested with bodies. The 6.5-month-old infants exhibited a preference for the familiar emotion, matching between faces and bodies.

In Experiment 2, 18 6.5-month-olds were tested with faces and bodies displaying anger and sadness. Infants familiarized to faces showed a familiarity …

Examining The Interaction Of Neonatal Alcohol And Hypoxia In Vitro, Megan L. Carter

Theses and Dissertations--Psychology

Exposure to ethanol (ETOH) during fetal development results in a range of cognitive/behavioral deficits. There are differences in sensitivity to the effects of ETOH that could be explained by other factors, such as hypoxia. Similar mechanisms of damage underlie both ETOH, more specifically ETOH withdrawal, and hypoxia. Based on this overlap, it was hypothesized that sub threshold levels of these insults may interact to produce increased damage in sensitive brain regions. This study used a rodent organotypic hippocampal slice culture model to investigate the interaction of hypoxia and ETOH withdrawal and to determine possible developmental differences in the sensitivity to …

Bayesian Analysis Of Parental Drinking Motives And Children's Adjustment, Aaron A. Duke

Theses and Dissertations--Psychology

Harm reduction strategies can mitigate against some of the deleterious effects of alcohol on families. These strategies are most feasible and cost-effective when they can be targeted at those who are most at risk. Previous studies examining the relation between parents’ alcohol use and their children’s psychological adjustment have failed to consider important contextual questions such as drinking motives. The current investigation set out to identify the extent to which parents’ drinking motives predict internalizing and externalizing psychopathology in their children. The investigation consisted of cross sectional analysis of parents’ drinking motives and their children’s adjustment using data from 154 …

The Whole Picture: Body Posture Recognition In Infancy, Alyson J. Hock

Theses and Dissertations--Psychology

Holistic image processing is tied to expertise and is characteristic of face and body processing by adults. Infants process faces holistically, but it is unknown whether infants process body information holistically. In the present study, we examined whether infants discriminate changes in body posture holistically. Body posture is an important nonverbal cue that signals emotion, intention, and goals of others even from a distance. In the current study, infants were tested for discrimination between body postures that differ in limb orientations in three conditions: in the context of the whole body, with just the limbs that change orientation, or with …

The Sexualized Girl: The Development Of An Expanded (Sexualized) Gender Stereotype Among Children, Ellen A. Stone

Theses and Dissertations--Psychology

The current study examined children’s stereotypes about sexualized girls. Elementary school children (n = 208) from the mid-South between the ages of 6 and 11 completed a survey assessing their stereotypes about sexualized girls and non-sexualized girls. Participants were asked to justify, in their own words, their responses to several stereotypic evaluations. Children’s cognitive development was analyzed through classification skill as a moderator of belief in stereotypes about girls. Results revealed that children perceived the sexualized girl to be more popular and better liked by boys than the non-sexualized girl. However, the sexualized girl was also rated as less athletic, …

Marital Conflict And Pubertal Timing: Stress And Security As Mediators Of Associations, Eric A. Haak

Theses and Dissertations--Psychology

The timing of pubertal development has important mental and physical health consequences. Individuals who enter puberty off-time are at greater risk for psychological disorders, social difficulties, and physical morbidity. One variable associated with early pubertal development is marital conflict. Life History Theory proposes that marital conflict signals an unreliable environment and promotes advanced pubertal timing to enhance reproductive fitness. Such calibrations allow individuals to unconsciously invest more resources in reproduction, following a quantity over quality approach. Despite research supporting the role of marital conflict in early-onset puberty, research has struggled to find a mechanism for this relationship. The current study …
