FIGURE 3.

Observed pupil size impacts on social evaluations. (A) The woman on the left is judged positive and attractive, and the one on the right with small pupils, as cold and distant. Picture is taken from Hess (1975). (B) A partner with dilating pupils is better trusted than a partner with static or constricting pupils, especially when the participant (on the left) synchronizes his own pupil size with the observed partner.
