Description
Several decades of research have concluded that child social functioning is a critical predictor of wellbeing across various developmental domains. Most scientists agree that both genetic and environmental influences play defining roles in social behavior; the processes by which they concurrently affect child development, however, has been the subject of less research. This work examines distinct mechanisms that shape child prosociality by examining genetic and environmental influences on development, via two empirical studies. The first study analyzed the evocative-reactive and the evocative-socially-mediated hypotheses as gene-environment correlation (rGE) mechanisms connecting the arginine vasopressin receptor 1a (AVPR1a) and dopamine receptor D2 (DRD2) genes, child prosocial behavior, and parent differential treatment (PDT). Findings present modest evidence for the evocative-reactive rGE hypothesis; specifically, AVPR1a marginally influenced child prosociality, which subsequently predicted mother preference in adolescence. The second study examined several gene-environment interactions (GxEs) in exploring how social environmental variables- positive and negative parenting- predicted child prosociality, as moderated by socially-implicated child genes, DRD2 and dopamine receptor D4 (DRD4). Findings indicated that while positive parenting was predictive of child prosociality regardless of genetic variants, the effects of negative parenting on child prosociality were dependent on child genetic variants. Together, findings from these studies suggest modest genetic and environmental influences on child behavior in middle childhood and adolescence, consistent with previous research and theory. Directions for future research are offered, and intervention and policy implications are discussed.

Description
Early childhood environment is critical to subsequent physical health in children and is influenced by children's primary caregivers \u2014 typically mothers. Maternal stress, one aspect of a child's environment, may shape the functioning of the child's physiological stress response system, which has been linked to later health outcomes, including pain. The current study evaluated whether: 1) early maternal stress, defined as maternal depressive symptoms and low socio-economic status, predicts later child pain; 2) early maternal stress relates to later child daily cortisol output; and 3) child's cortisol output across the day mediates the relation between early maternal stress and child pain. Maternal stress was assessed via questionnaires at twin age 12-months. At twin age seven years, twins' salivary cortisol was collected three times per day for three days. At twin age nine years, twins rated how often they experienced stomach, headache, and back pain weekly or more frequently. Results of multilevel linear and logistic regression analyses showed that early maternal stress did not predict later children's daily cortisol output or extent of child pain. Therefore, findings were inconsistent with the proposed mediation model. However, there was a marginally significant negative relation between child daily cortisol output and later extent of child pain. Current findings suggest that functioning of the stress response system, reflected in cortisol output, may have implications for the development of child pain. Future work evaluating intensely stressful early environments may provide clues about the links between a child's early environment and the development of his/her stress response system.

Description
Understanding sources of knowledge (e.g., seeing leads to knowing) is an important ability in young children’s theory of mind development. The research presented here measured if children were better at reporting their own versus another person’s knowledge states, which would indicate the presence of introspection. Children had to report when the person (self or other) had knowledge or ignorance after looking into one box and not looking into another box. In Study 1 (N = 66), 3- and 4-year-olds found the other-version of the task harder than the self-version whereas 5-year-olds performed near ceiling on both versions. This effect replicated in Study 2 (N = 43), which included familiarization trials to make sure children understood the question format. This finding is in support of the presence of introspection in preschool-aged children. In the same studies, children also showed evidence for theorizing about their own and others knowledge states in a guessing task (Study 1) and in true and false belief tasks (Study 2). These findings together indicate both introspection and theorizing are present during young children's theory of mind development.

Description
This dissertation examined how anxiety levels and social competence change across the course of early elementary school, as well as how individual differences at the transition to kindergarten may influence these trajectories. Previous research has supported unidirectional relations among anxiety and social competence, but few studies explore how inter- and intra-individual changes in social competence and anxiety may be related across time. From a developmental perspective, studying these trajectories following the transition to kindergarten is important, as cognitive and emotion regulation capacities increase markedly across kindergarten, and the relative success with which children navigate this transition can have a bearing on future social and emotional functioning across elementary school. In addition, given gender differences in anxiety manifestation and social competence development broadly, gender differences were also examined in an exploratory manner. Data from parent and teacher reports of a community sample of 291 children across kindergarten, 1st, and 2nd grades were analyzed. Results from bivariate growth models revealed steeper increases in anxiety, relative to peers in the sample, were associated with steeper decreases in social competence across time. This finding held after controlling for externalizing behavior problems at each time point, which suggests that relations among anxiety and social competence may be independent of other behavior problems commonly associated with poor social adjustment. Temperament variables were associated with changes in social competence, such that purportedly "risky" temperament traits of higher negative emotionality and lower attention control were associated with concurrently lower social competence in kindergarten, but with relatively steeper increases in social competence across time. Temperament variables in kindergarten were unrelated with changes in anxiety across time. Gender differences in relations among anxiety in kindergarten and growth in social competence also were revealed. Findings for teacher and parent reports of child behavior varied. Results are discussed with respect to contexts that may drive differences between parent and teacher reports of child behavior, as well as key developmental considerations that may help to explain why kindergarten temperament variables examined herein appear to predict changes in social competence but not changes in anxiety levels.

Description
Many children who testify to alleged sexual abuse struggle to answer questions about touching, likely because attorneys and children may operate under different definitions of “touch.” However, little is known about how children define touch, and the most productive question type for eliciting reports of touching has yet to be determined. In the present investigation, Study 1 examined (N = 64, 5 - 12 years of age) children’s testimonies to identify the sources of misunderstanding when children report abusive touch in court. In light of the language difficulties observed in Study 1, specifically, that attorneys and children appeared to be operating under different definitions of touch, a laboratory study (Study 2) was conducted to examine (N = 95, 4 - 7 years of age) children’s definition of touch, and how children reported touching in response to open-ended wh- questions, compared to close-ended yes
o questions. Body contact (i.e., manual and non-manual touch, compared to touching with an object) was most closely representative of children’s definition of touch. Additionally, children reported touch more often, and provided more informative reports of touch, in response to wh- questions, compared to yes
o questions. These findings demonstrated that children’s definition of touch exists on a scale, and through asking specific, open-ended wh- questions attorneys can elicit reports of touching from children even when definitional discrepancies are present.
