Children can acquire novel word meanings by using pragmatic cues. However, previous literature has frequently focused on in-the-moment word-to-meaning mappings, not delayed retention of novel vocabulary. Here, we examine how children use pragmatics as they learn and retain novel words. Thirty-three younger children (mean age: 5.0, range: 4.0-6.0,…

When we watch movies, we consider the characters' mental states in order to understand and predict the narrative. Recent work in functional magnetic resonance imaging (fMRI) uses movie-viewing paradigms to measure functional responses in brain regions recruited for such mental state reasoning (the theory of mind ["ToM"] network). Here,…

This experimental research assessed the influence of graded levels of self-distancing--psychological distancing from one's egocentric perspective--on executive function (EF) in young children. Three- (n = 48) and 5-year-old (n = 48) children were randomly assigned to one of four manipulations of distance from the self (from proximal to distal:…

Morality is an evolved aspect of human nature, yet is heavily influenced by cultural environment. This developmental study adopted an integrative approach by combining measures of socioeconomic status (SES), executive function, affective sharing, empathic concern, theory of mind, and moral judgment in predicting sharing behavior in children (N =…

Theory of mind (ToM) development, assessed via "litmus" false belief tests, is severely delayed in autism, but the standard testing procedure may underestimate these children's genuine understanding. To explore this, we developed a novel test involving competition to win a reward as the motive for tracking other players' beliefs (the…

Theory of mind requires belief- "and" desire-understanding. Event-related brain potential (ERP) research on belief- and desire-reasoning in adults found mid-frontal activations for both desires and beliefs, and selective right-posterior activations "only" for beliefs. Developmentally, children understand desires before beliefs; thus, a critical…

Temperament dimensions influence children's approach to and participation in social interactive experiences which reflect and impact children's social understandings. Therefore, temperament differences might substantially impact theory-of-mind development in early childhood. Using longitudinal data, we report that certain early temperament…
