Stimuli
The stimuli were images of a female model displaying a neutral expression and with her head and part of her upper body visible, taken from Hietanen. She was photographed with her gaze direction congruent with her head orientation, so that gaze and head direction were always correlated with each other. Five different pictures were used: a front view of the head and body oriented straight to the camera (see Figure 1a); a front view of the body but with the head oriented 40 degrees to the left and right; and the head and body both oriented 40 degrees from the front view to the left and right.
