The behavioural expression of empathy to others' pain versus others' sadness in young children

Little is known about how children develop or express their empathy for another individual's pain. The current study compared the behavioural expression of empathy for pain with that for emotion, specifically sadness, in children. One hundred twenty children (60 boys, 60 girls) between the ages of 18 and 36 months (M=26.44 months; SD=5.17) were assessed for their empathy-related behavioural responses to simulations of an adult's pain and sadness, each presented separately. Children were more likely to be distressed by, but also more likely to be prosocially responsive to, another's sadness. Conversely, children were more likely to actively play during another's pain. Despite these differences, principal component analyses conducted separately for pain and sadness revealed conceptual similarities across simulation type. Components labelled as Empathic Concern and Personal Distress emerged for both simulations. Hierarchical regression analyses examining the influence of developmental (ie, age, sex) and interindividual (ie, temperament, social-emotional development, language abilities) variables of interest in children's empathy-related responses were conducted for each pain and sadness component. Age differences emerged only for pain. There were no sex differences for either simulation. Temperament showed some predictive value in how children would respond to sadness. Social-emotional variables showed some predictive value in how children would respond to pain and sadness. Language showed very little predictive value. These findings highlight both conceptual similarities across, and important differences between, children's expressions of empathy for pain and for sadness. Pain appears to be more easily ignored and results in fewer prosocial responses in children.
