The Role Of Multiple Object Views In Early Word Learning: A Dynamic Process, Abigail Julian Dimercurio

Doctoral Dissertations

Word learning is a complex process that involves multiple interacting components. One of these components is the motor system. During the first few years of development, the onset of motor skills predicts the development of language skills such that earlier onsets of crawling and walking relate to greater vocabulary sizes. It is thought that this relationship occurs due to a developmental cascade where gaining locomotive skills allows for greater environmental exploration, thus, more opportunities to learn new words. One area of interest in this cascade is object manipulation. Moving objects in a way that creates multiple views is related to …

The Effect Of Maternal Borderline Personality Disorder And Child Temperament On Mother-Child Synchrony, Christina Gabriela Mena

Doctoral Dissertations

Maternal borderline personality disorder (BPD) and difficult child temperament have individually been associated with reduced quality of mother-child interactions. The current study examined synchrony (a dyadic construct measuring quality of interaction) during a coded observational task in a sample of mothers with BPD and their young children ages 4-7 (n = 36) compared to normative comparisons (n = 34). These mothers’ self-reported borderline features were also used to examine dyad synchrony across the sample as a whole. We also examined the association between child temperament and synchrony as well as the potential moderating effect child temperament has on the relationship …

Infant Locomotor Skill Development In The Context Of Mother-Infant Interactions, Sabrina Lynn Thurman

Doctoral Dissertations

The acquisition of locomotor skills and transitions within them leads to changes in infants’ exploratory abilities and interactive behaviors, which affects several aspects of parent-infant exchanges. Here, we tracked how the onset of crawling and walking affected both infants’ and mothers’ spatial exploration, interactive behaviors, and use of postures in 10-minute free play sessions held in a laboratory setting. Thirteen infants and their mothers were followed longitudinally with biweekly sessions occurring from before crawling onset until infants had two months walking experience. We focused on two 6-session transition periods centered around the onsets of hands-and-knees crawling and walking. Behavioral data …

Bidirectional Associations Between Parenting Behavior And Child Callous-Unemotional Traits: Do Delinquent Peer Affiliations And/Or Parental Psychopathology Moderate These Links?, Amber Rochelle Wimsatt

Doctoral Dissertations

The current study examined bidirectional associations between callous-unemotional (CU) traits and parenting dimensions and evaluated whether these associations changed as children aged. Furthermore, this study extended the literature by examining whether these relations were moderated by delinquent peer affiliation and/or parental depression. Proposed relations were examined using a longitudinal sample of 120 aggressive boys (59.6%) and girls (40.4%) who were in the 4^th grade (M = 10.56 years, SD = .56) at baseline and were followed over four years. A series of generalized estimating equation [GEE] models revealed reciprocal relations between CU traits and corporal punishment. Consistent with …

The Effects Of Social Support On At-Risk Youth, Christi Lanet Culpepper

Doctoral Dissertations

Social support is conceptualized as a protective factor that buffers against distress and dysfunction. Social support can be beneficial to all individuals and is usually available through a support system consisting of family and friends. Unfortunately, there are populations that lack effective support systems and consequently do not receive social support. One such population is at-risk youth. In this project, I examined the effects of social support, within the context of participation in youth programs, on the academic, emotional, and behavioral functioning of at-risk youth. Twenty-three adolescents participating in three youth programs were assessed at three time points: the beginning …

Developmental Trajectories Of Adhd Symptoms To Adolescent Substance Use: What Influence Do Peer, Family And Neighborhood Factors Have?, Michael Lawrence Vitulano

Doctoral Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) has been consistently linked to risk for early substance use. However, the potential mediating mechanisms and moderators of this association remain unclear. The current study examined peer rejection, school bonding and internalizing problems as potential mediators of the association between childhood ADHD symptoms and adolescent substance use in a longitudinal study following children from fourth to ninth grade. Results suggest that ADHD symptoms follow a path to early initiation of tobacco use through the combined effects of peer rejection and internalizing problems as well as through internalizing problems alone. ADHD symptoms did not follow developmental pathways to …

Associations Between The Subtypes Of Aggression, Parenting Styles And Psychiatric Symptomatology In Children On A Psychiatric Inpatient Unit, Jamie Lee Rathert

Doctoral Dissertations

Childhood aggression often precedes more costly problem behavior that may result in psychiatric hospitalization. However, aggression is not a unidimensional construct, as there are subdimensions of aggression. A common way that aggression is divided is by the motivation behind the behavior, namely proactive and reactive aggression. Proactive aggression is calculated in nature, whereas reactive aggression occurs in response to a perceived threat. Some evidence suggests differential outcomes for these aggression subtypes; thus, further understanding of the link between the subtypes of aggression and psychiatric problems may help to refine current prevention efforts and reduce the number of hospitalizations.

Consistent with …

The Intersection Between Home And School: Developing A Scale To Measure Parental Perceptions Of Childhood School Stress, Teresa Marie Henke

Doctoral Dissertations

Abstract

Parents in the home and educators in the schools are key adults in the most important contexts in the daily lives of school-age children. In the demanding, achievement, and accountability oriented culture of today, it is expected that children experience normal everyday stressors as they move between these two environments. The impact of stress related to daily hassles has been reported to have both cognitive and physical effects on the present and future well-being of children. This study represented an attempt to advance the understanding of childhood stress in the intersection between school and home by investigating the perceptions …

Mindfulness And Self-Compassion: Exploring Pathways To Adolescent Emotional Well-Being, Karen Leslie Bluth

Doctoral Dissertations

Adolescents today are confronted with the compounded stressors of life in our high-pressured society and the cognitive, physiological, and emotional changes that are characteristic of this stage of development. As a result, they often struggle with self-doubt, leading to depression, anxiety, and maladaptive trajectories. Mindfulness, or paying attention in the moment in an intentional and purposeful way, has been reported to have positive effects on emotional well-being in adults, and shows promise for similar results in recent research with children and adolescents.

Moreover, the mechanisms through which being mindful achieves positive outcomes has only recently been explored, and has not …

Positive Functioning Among Chinese Adolescents: Conceptualizing A Framework And Testing Effects Of Parenting, Mingzhu Xia

Doctoral Dissertations

Chinese adolescents’ development has received increasing attention over recent decades. However, following a traditional deficit model, most of the attention has been on problematic functioning of adolescents (e.g. depression). This emphasis is not consistent with evidence that the large majority of Chinese adolescents do not manifest such problem behaviors. Little is known about positive functioning among Chinese adolescents and how it is related to key socialization practices such as parenting. The purpose of the present study was to begin to fill these gaps.

Using theory, past empirical practice, and characteristics of Chinese culture, the study posited a second-order structure for …
