Elements of a theory of social competence : socio-cognitive and behavioral contributions in typical development

Humans are characterized by species-specific social skills and interactions, which direct much of their behaviors, dictate thought processes and form the foundations of human consciousness and reality. These social abilities are highly complex and intricate, involving a large range of developmentally acquired skills allowing the perception, processing, interpretation and response to dynamic social stimuli. The fine-tuning of these diverse abilities across the lifespan contributes to an individual’s social competence, allowing the navigation of the social world. Smooth and adaptive social development is supported by core cognitive functions (e.g. intellectual ability, language, memory, attention, visual-perceptive skills), as well as by specific skills (e.g. theory of mind, empathy, emotion recognition, perspective taking, intent attribution, moral reasoning) referred to under the umbrella of “social cognition” and subsumed by neural structures and networks of the “social brain”. Despite strong evidence supporting the associations between neural, cognitive and social functioning, much remains to be learned about the interplay between socio-cognitive abilities during development, the external influence of environmental factors, as well as their individual and additive impact on social behavior. The main objective of this dissertation was to study two manifestations of social competence in typical development, namely, social cognition and social behavior. The SOCIAL model (Beauchamp & Anderson, 2010) is used as the theoretical and empirical framework providing fertile ground for the investigation of multiple facets of the development of social competence and a better understanding of the global interplay of socio-cognitive skills (e.g., moral reasoning and perspective taking) and social behavior more broadly. The first study explores the contribution of cognitive (theory of mind) and affective (empathy) aspects of perspective taking to moral reasoning and social behavior in typically developing children and adolescents. An innovative neuropsychological tool for assessing moral reasoning, the Socio-Moral Reasoning Aptitude Level (So-Moral), was used to enhance the ecological value of the construct. Everyday socio-moral reasoning dilemmas were presented to children and adolescents to evaluate their moral maturity, and assessments of theory of mind, empathy and social behavior were also completed. Jointly, both aspects of perspective taking (theory of mind and empathy) predicted moral reasoning maturity in children, but not in adolescents. Poorer moral reasoning skills were associated with more externalizing behavior problems across the age span, but no associations were found with respect to prosocial behavior. Theory of mind skills were independent predictors of moral reasoning, suggesting that a cognitive understanding of the situation may be especially useful when children are asked to reason about a moral conflict. Contributing factors to moral reasoning differed in children and adolescents, suggesting differential underlying mechanisms. The second study investigates the contribution of external influences, as operationalized by time spent playing video games, to social behavior. A secondary objective was to add to the growing body of literature exploring associations between video game playing, social cognition and social behavior, in an age group less frequently focused on (elementary school-aged children). The main results of the study indicate that children who spend less time per week playing video games have greater prosocial tendencies, but no association was found with behavior problems. Findings highlight the possibility that real-life, complex, and nuanced social interactions outside screen-based play may be central to fostering social competence skills in children.  Overall, the results of the studies presented in this dissertation contribute to building a more comprehensive picture of the complex interplay between social cognition, social experience and social competence during typical development. Findings offer new avenues for improving theoretical, empirical and clinical knowledge of social development and provide an empirical basis for the development of social skills intervention programs as well as social cognition assessment tools.
