We examined the associations between language skills and concern and disregard for others in young children assessed longitudinally at ages 14, 20, 24, and 36 months, testing the hypothesis that language skills have a specific role (distinct from that of general cognitive ability) in the development of concern and disregard for others. We found…

Background: Prediction of antisocial behavior is important, given its adverse impact on both the individuals engaging in antisocial behavior and society. Additional research identifying early predictors of future antisocial behavior, or antisocial propensity, is needed. The present study tested the hypothesis that both concern for others and…

Empathy is the combined ability to interpret the emotional states of others and experience resultant, related emotions. The relation between prefrontal electroencephalographic asymmetry and emotion in children is well known. The association between positive emotion (assessed via parent report), empathy (measured via observation), and…

Within a sample of 584 twins aged 12 to 25 months (292 pairs) studied longitudinally, positive affect measured through two laboratory pleasure episodes and maternal report at 12 and 22 months significantly predicted empathy-related helping and hypothesis testing assessed between 19 and 25 months. Girls showed significantly more concern than did…

Observational measures of monozygotic and dizygotic twins' reactions to simulations of distress in others were obtained when the twins were 14 and 20 months old. Components of concern for others increased with age. Girls scored higher than boys on most measures. There was modest evidence for heritability of empathy. (BC)

Examined role of infant and toddler temperament in predicting 2-year olds' empathy. Found that children showed relatively more concern for mother's distress, but were also responsive to unfamiliar victims. Unreacting infants showing little affect also showed less empathy toward the unfamiliar adult almost two years later. Inhibition toward…

Over one year, mothers observed the responses of their one-year-old children to distresses the children caused and witnessed in others. Children's prosocial behaviors, and reparative behaviors after they had caused distress, increased in frequency over the year. These behaviors were accompanied by changes in self-recognition. (BC)

This 9-month naturalistic study investigated maternal influence on the responses of 1 1/2- to 2-year-old infants to emotional distress events occurring in the family environment. Mothers were trained to report details of distress incidents, of the child's reactions to the person in distress, and of the mother's own response to the child and to the…

Examined development of concern and externalizing problems in children at three behavior problem levels. Found no group differences in concern at 4-5 years. Concern in children with clinical behavior problems decreased by 6-7 years. Greater concern at 4-5 or at 6-7 years predicted decreased stability and severity of externalizing problems by 6-7…
