Nonverbal behavior was manipulated in
accordance with procedures used by Greenlees et al. and
. In the dominant body language condition, the actors were asked
to (i) stand and walk with an erect posture that involved pulling the shoulders back
and pushing the chest out; (ii) slightly spread the limbs from the torso to occupy
more space; (iii) hold the head up with the chin parallel to the ground so that their
eyes were looking directly at the camera; and (iv) to look directly at the camera
for 90% of the time.
