Why Are Extraverts More Popular? Oral Fluency Mediates the Effect of Extraversion on Popularity in Middle Childhood

Abstract

In a sample of 7– to 8–year–old children (N = 760), we examined the associations between personality traits, oral fluency and sociometric popularity. Extending upon research conducted with older populations, we found parent ratings of extraversion at age 7 to predict popularity one year later. More importantly, we expected and found teacher–rated oral fluency to partially mediate the positive association between extraversion and popularity. This mediation effect was independent of psychometrically assessed working memory, academic skills and gender. Our results can be interpreted as suggesting that a Matthew effect, similar to the one proposed for early reading skills and cognitive ability, may be operating in the domain of social competence.
