Children's emotional and physiological responses to interadult angry behavior: the role of history of interparental hostility.

Relations between history of marital discord and responses to interadult angry behavior were examined in preschoolers. Children watched/listened to an angry interaction between two adults, while their heart rate (HR) and skin conductance response (SCR) and skin conductance level (SCL) were monitored; then they were interviewed about their emotional responses to the argument. Children were also videotaped during the session and their overt behavioral distress responses were coded. In comparison to children from low-conflict homes, children from high-conflict homes (a) exhibited more overt behavioral distress in response to the argument, and (b) perceived the angry interaction as less negative in affect. Children's HR reactivity to the angry interaction was influenced by both marital conflict and the gender of the subject. In comparison to girls from low-conflict homes, those from high-conflict homes exhibited more HR reactivity to the argument. For boys, physical violence in the home was negatively associated with HR reactivity.
