Drawing on an integrative framework of emotions, my dissertation grapples with the social and emotional development–specifically well-being–of Black children amid anti-Black violence within educational spaces (e.g., playgrounds, classrooms, wellness centers). To do so, this dissertation explores the affective dimensions or social function of emotions among Black students ages 4 to 10 within educational spaces– that is, how emotions shape their social interactions and how social interactions shape their emotions. There is limited scholarship on the everyday and multifaceted relationship between emotions and social interactions among Black students in educational spaces (Camangian & Cariaga, 2022; Dumas & Nelson, 2016; Legette, Rogers, & Warren, 2022). A vital component of this study includes deep and rich descriptions of Black students’ emotional well-being, which has implications for their mental health by capturing the social function of emotions across educational spaces. By bringing together insights from emotion science with Black placemaking, this dissertation (a) How do emotions shape social interactions, and how do social interactions shape emotions? (b) in what ways are Black students exploring and processing the relationship between their emotions and social interactions, (c) how are emotions moving through and sticking to the everydayness of Black student’s social environments (objects, spaces/places, language, tone, memory, body movements, cultures, environments, identity, and events) and construct the ways they build relationships (Ahmed, 2004, 2015; Gregg & Seigworth, 2010), and (d) considers how Black children’s emotions can provide crucial insight into promoting and protecting their emotional well-being in educational spaces. This dissertation leverages insights from, responds to limitations of, and builds upon research in psychology, sociology, Black studies, child studies, and education on the topic of emotions. This dissertation utilized three qualitative methods—participant observations, semi-structured, in-depth, and open-ended interviews, and sociological video analysis. Findings shed new light on how emotions play a central role in the processes and factors that (re)produce and reduce inequality in the emotional everyday lives of Black students in educational settings, ultimately shaping their emotional well-being and mental health. Findings also articulate the multidimensionality of emotions, which contribute to the crucial and urgent work to improve the mental health and well-being of Black students. The study results have critical implications for understanding and supporting Black students’ healthy social and emotional development in education spaces.
