Appearance-related self-esteem is a facet of body image that encompasses the evaluative components of an individual's self-concept that pertains to their own physical appearance. Knowledge regarding how appearance-related self-esteem functions in adolescent social groups is scant in the literature and there is limited research using linear methods suggesting that adolescents can influence the appearance-related self-esteem of their peers. Given the negative consequences of negative feelings about one's appearance later in life, I examined how appearance-related self-esteem develops and relates to adolescent social processes during the transition to middle school. This dissertation investigated how appearance-related self-esteem related to the social processes of selection, similarity, and influence. I further explored the effect of gender on social processes and appearance-related self-esteem. Appearance-related self-esteem was not related to social processes of selection, similarity, or influence. Gender similarity was present in the network, such that adolescents were more likely to select same-gender peers than other-gender peers. Additionally, an effect of gender on appearance-related self-esteem was present, such that boys' appearance-related self-esteem increased over time more than girls'. Findings from the current dissertation provide foundational first steps in identifying the ways that peers impact appearance-related self-esteem during adolescence and provide insights toward understanding how different gender pathways around appearance-related self-esteem may develop over time.

Academic tracking has long been a subject of debate due to its potential impact on educational equity, with students who are tracked highly receiving a higher quality education in comparison to students tracked lowly. These disparities in education quality may be affecting students’ outcomes, as it has been demonstrated that the short-term academic outcomes of students, such as their grades, tend to be affected by their academic track positioning. This dissertation builds upon these previous findings by utilizing a subsample of 20,584 students from the High School Longitudinal Study (2009) to examine the relation between academic track positioning and post-secondary education attendance, program length, college major, and expected future job. Additionally, the relation between academic tracking and each of these outcomes was also assessed using mediation, with potential mediators including education aspiration, expectations, and academic self-efficacy. Findings suggest that academic track positioning in math and science are influential in students’ post-secondary and career outcomes, with students who are positioned highly in either subject having greater post-secondary attendance, program length, higher representation in STEM college majors, and expectations for future jobs in STEM fields in comparison to students tracked lowly. Additionally, education aspirations and expectations mediated the relations between math academic track positioning and each of the outcomes, although the effects were small in size. Educators should consider exploring avenues for improving education quality in low academic tracks.

During the formative years, habits, outlooks, and attitudes develop which influence social interaction throughout life. Because empathy is crucial in social interaction, empathy development should be supported. Evidence of empathy is first observed around the age of two (Radke-Yarrow et al., 1983, 1984; Spinrad & Fabes, 2009). The purpose of this thesis is to examine empathy in children from multiple perspectives. The scientific literature reviews the discovery of the mirror neuron system (MNS). A study on nine- and ten-year-old children showed a correlation between MNS activity and empathic concern (Pfeifer et al. 2008). Another study with a mean age of 11 demonstrated that high emotional intelligence (EI) resulted in more nominations for "cooperation" and less for "aggression" (Petrides, Sangareau, Furnham & Frederickson, 2006). The three most common EI tests (MSCEIT, TEIQue, Bar-On) are modeled to measure empathy (Bar-On, 2006; Goleman 1998, 1995; Mayer & Caruso 1997; Petrides & Furnham 2001). Psychologists agree that low measures are linked to narcissistic and aggressive behavior. The Observational Study analyzed both evidence of empathy and a lack of empathy in interactions with three- and four-year-old children. Personal experiences were also shared on how empathy was understood and practiced. Lastly, the children's short story was written to support empathy development through fiction-reading.

The overall goal of this dissertation was to examine teacher characteristics, teachers’ beliefs, and contextual factors that may motivate teachers’ decisions to engage in high quality teacher-child interactions. I use two complementary studies to meet this goal. These two studies provide insight into several aspects of early childhood teachers’ and children’s interactions including the complexity of the conversations and teachers’ supportive practices. Findings from both studies reveal that teachers are selective in how they distribute their time and attention across various types of high-quality interactions with children. Study 1suggests that teachers’ perception of how often children interact with one another motivates their decisions to engage in high quality teacher-child interactions (i.e., facilitate children’s peer interactions). Study 2 suggests that teacher well-being, specifically teacher depression, limits the extent to which teachers engage in high quality interactions (i.e., complex conversations with children). Importantly, this dissertation also showed that teachers’ motivation for engaging in teacher-child interactions does not stem from their own characteristics or perceptions alone. In addition to these factors, contextual aspects of teacher-child interactions also appear to influence teachers’ motivation to engage in high-quality teacher child interactions. Study 1 revealed that the gender composition of the children involved in each teacher-child interaction was associated with the extent to which teachers use facilitative practices, as well as with the direction and magnitude of both quality and frequency effects on teachers’ facilitation. Moreover, Study 2 revealed that the relation between teacher depression and complex conversations is changed when teachers and children are engaged in academic activities (e.g., math, books, language) relative to play or routine activities. In both Study 1 and 2, I used a teacher-focused observational coding system. Use of this observational coding system contributes novel, objective information about teacher-child interactions, as prior work on teacher-child interactions has most often relied on teachers’ self-reports of how often they interact with students. Findings from this dissertation will contribute new knowledge about teacher and contextual classroom characteristics and teacher-child interactions that will inform efforts to promote positive teacher child interactions and, in turn, student and teacher well-being.

Preschool teachers have the opportunity to facilitate children's play with a variety of classroom activities. Preschool activities can be categorized as masculine, feminine, and gender-neutral based on children's preferences. Understanding how and why teachers facilitate children's play with feminine, masculine, and gender-neutral activities is important because children's engagement in gender typed activities has been linked to cognitive development. The current study extends previous and outdated research on teachers' engagement in gender-typed classroom activities by using a teacher-focal observational coding system and survey data to assess the frequency at which, with whom, and why teachers facilitate feminine, masculine, and gender-neutral activities. Results reveal teachers facilitate gender-neutral and masculine activities more frequently than feminine activities. However, facilitation of these activities is qualified by with whom the teacher interacts and the classroom context. During free play, teachers facilitate gender-typed activities in stereotypic ways, facilitating masculine activities with boys more than with girls and feminine activities with girls more than with boys. Although, during structured settings, teachers do not facilitate masculine and feminine activities at different frequencies. Finally, in both free play and structured settings, teachers' gender attitudes do not seem to be strong predictors of their facilitation of gender-typed and gender-neutral activities with the exception of teachers' facilitation of feminine activities during structured settings. The present findings address important issues in educational and developmental research by investigating teachers' gendered classroom practices.

This study drew upon a bioecological framework to empirically investigate the relations between environmental chaos and preschoolers' language across time, including the potentially mediating roles of children's effortful control and parenting. Child sex also was examined as a moderator of these relations. For this study, the following data were collected at 30, 42, and 54 months of age. Household chaos and (at 30 months) socioeconomic status (SES) were reported by mothers. Children's effortful control (EC) was rated by mothers and nonparental caregivers, and was observed during a number of laboratory tasks. Maternal vocalizations were assessed during free play sessions with their children (at 30 and 42 months), and supportive and unsupportive parenting behaviors and affect were observed during free play and teaching tasks at each age. Mothers also reported on their own reactions to children's negative emotions. Finally, (at 54 months) children's expressive and receptive language was measured with a standard assessment. Structural equation modeling and path analyses indicated that SES at 30 months and greater levels of household chaos at 42 months predicted not only poorer language skills, but also deficits in children's EC and less supportive parenting in low-income mothers at 54 months, even when controlling for stability in these constructs. Children's effortful control at 42 months, but not parenting, positively predicted later language, suggesting that EC may play a mediating role in the relations between household chaos, as well as SES, and preschoolers' language abilities. Child sex did not moderate the pattern of relations. Post-hoc analyses also indicated that the negative relation between chaos and language was significant only for children who had low EC at 42 months. This study represents a much-needed addition to the currently limited longitudinal research examining environmental chaos and children's developmental outcomes. Importantly, findings from this study elucidate an important process underlying the links between chaos and children's language development, which can inform interventions and policies designed to support families and children living in chaotic home environments.

Studies of peer victimization typically focus on behavioral characteristics of the victims, and frequently overlook the role that peers may play. The current study extended previous research by examining how time spent with two types of peers (externalizing and socially competent) can serve as a risk or protective factor for preschoolers' victimization, and how victimization may differ for boys and girls. In addition, the study explored how affiliating with same-sex and other-sex externalizing and socially competent peers may differentially relate to victimization. Results showed that girls who affiliated with externalizing female peers were significantly more at risk for victimization. In addition, boys and girls who spent time with socially competent male peers (but not female peers) negatively predicted victimization. The results indicate that children's peers, in certain circumstances, may play an important role in victimization. These findings also highlight the importance of considering children's and peers' gender when studying peer processes.
