Emotions are part of interpersonal communication and adequate use of emotions are vital for successful interaction. To see if children with ASD express emotions to the same extent, we compared 17 children with ASD (age range: 3-6 years) to 33 typically developing children of the same age on both on behavioral emotion expression and on psychophysiological arousal. The behavioral expression and psychophysiological parameters of emotion (heart rate and skin conductance level) were continuously measured during rest and a fear inducing paradigm. The groups did not differ on the intensity of negative or positive emotion expression. The ASD group had lower skin conductance levels during rest compared to the typically developing children and a more pronounced increase in psychophysiological arousal in response to a fear paradigm. To integrate these two separate measures of emotion, the concordance between the behavioral and psychophysiological components was evaluated. Negative emotions were related to heart rate in the ASD group and to skin conductance in the control group, but the strength of the correlation did not differ significantly between the two groups. Considering the health and behavioral risks associated with abnormal levels of emotional arousal, the specific effects of deviant emotional arousal in children with ASD need to be further explored. Targeting psychophysiological levels of arousal in interventions might be an effective approach to ameliorate challenging behavior in children with ASD.Show less
