Figure 1.
Example trial of the passive viewing task.
Each trial started with a central fixation cross, followed by a film clip. The clips started with a neutral expression (in the figure represented by a gray rectangle), followed by a morph into a dynamic emotional expression and ended with a still of the full-blown emotion (in the figure represented by a white rectangle). Each trial ended with an inter-stimulus interval.

Facial mimicry response to emotional facial expressions in DBD, ADHD and healthy controls.
No significant differences were shown between groups in mean EMG amplitude as a percentage from baseline neutral expression for SAD, FEAR, ANGRY and HAPPY MIMICRY presented for healthy controls, children with attention-deficit/hyperactivity disorder (ADHD) and children with disruptive behavior disorder (DBD). Error bars represent +/− 1 standard error.
