This study explored the development of theory of mind (ToM) in 80 Swedish-speaking 3- to 5-year-olds, a previously unstudied language and culture. The ToM scale was translated and tested in a Swedish context. The results show that the ToM abilities improve significantly with age. In addition, a gender difference was observed for the whole sample,…

Research Findings: Emotion knowledge is a core developmental process that has a documented relation to other aspects of social-emotional functioning, including social competence, emotion regulation, and behavior problems. Children who are maltreated have been found to have compromised emotion knowledge skills as well as higher levels of behavior…

Two studies investigated young 2- and 3-year-old Turkish children's developing understanding of normativity and freedom to act in games. As expected, children, especially 3-year-olds, protested more when there was a norm violation than when there was none. Surprisingly, however, no decrease in normative protest was observed even when the actor…

We developed a gift-giving task requiring children to identify their mother's desire, when her desire differed from theirs. We found a developmental change: 3- and 4-year-olds performed more poorly than 5-year-olds (Experiment 1). A modified version of this task (Experiment 2) revealed that 3-, 4-, and 5-year-olds whose desires had been fulfilled…

To investigate the relation between cognitive and affective social understanding, Japanese 4- to 8-year-olds received tasks of first- and second-order false beliefs and prosocial and self-presentational display rules. From 6 to 8 years, children comprehended display rules, as well as second-order false belief, using social pressures justifications…

This study investigated associations between mother-infant interactions and children's subsequent understanding of mind and emotion. Mothers' tendency to comment on their infants' internal world and their general sensitivity to their infants' internal states were measured through coded play interactions at 10 months. The latter measurement…

This longitudinal study examined individual differences and correlates of focused attention when toddlers were approximately 18 months old (T1; n = 256) and a year later (T2; n = 230). Toddlers' attention and negative emotionality were reported by mothers and non-parental caregivers and rated globally by observers. Toddlers' focused attention also…

Emotion regulation cannot be temporally distinguished from emotion in the brain, but activation patterns in prefrontal cortex appear to mediate cognitive control during emotion episodes. Frontal event-related potentials (ERPs) can tap cognitive control hypothetically mediated by the anterior cingulate cortex, and developmentalists have used these…
