Facial EMG and heart rate responses to emotion-inducing film clips in boys with disruptive behavior disorders.

We examined aspects of emotional empathy across different physiological response systems in boys with disruptive behavior disorders (DBD) and normal controls. Heart rate (HR) and electromyographic (EMG) reactivity in zygomaticus major and corrugator supercilii muscles were monitored during sadness-, anger-, or happiness-inducing film clips. Relative to controls, DBD boys showed significantly less HR reduction during sadness, and a smaller increase in corrugator EMG activity both during sadness and anger.

Facial EMG responses to dynamic emotional facial expressions in boys with disruptive behavior disorders.

Based on the assumption that facial mimicry is a key factor in emotional empathy, and clinical observations that children with disruptive behavior disorders (DBD) are weak empathizers, the present study explored whether DBD boys are less facially responsive to facial expressions of emotions than normal controls. Facial electromyographic (EMG) activity in the zygomaticus major and corrugator supercilii muscle regions, and heart rate activity were studied in 22 clinically referred 8-12-year-old DBD boys and 22 age-matched normal controls during exposure to dynamic happy and angry expressions. Dispositional emotional empathy was assessed by a self-report questionnaire for children.

Empathy in boys with disruptive behavior disorders.

Background: The present study examined empathy in 8- to 12-year-old clinically referred boys with disruptive behavior disorders (DBD) (n=25) and age-matched normal controls (n=24).

Method: Situational empathy was assessed by children's emotional and cognitive responses to six empathy-inducing vignettes (displaying sadness, anger or happiness). Dispositional affective empathy was measured by a self-report questionnaire for children.
