The present work investigates pupillary reactions induced by exposure to faces with diferent levels of trustworthiness. Participants’ (N=69) pupillary changes were recorded while they viewed white male faces with a neutral expression varying on facial trustworthiness. Results suggest that reward processing and pupil mimicry are relevant mechanisms driving participants’ pupil reactions. However, when including both factors in one statistical model, pupil mimicry seems to be a stronger predictor than reward processing of participants’ pupil dilation. Results are discussed in light of pupillometry evidence

Abstract

The present work investigates pupillary reactions induced by exposure to faces with diferent levels of trustworthiness. Participants’ (N=69) pupillary changes were recorded while they viewed white male faces with a neutral expression varying on facial trustworthiness. Results suggest that reward processing and pupil mimicry are relevant mechanisms driving participants’ pupil reactions. However, when including both factors in one statistical model, pupil mimicry seems to be a stronger predictor than reward processing of participants’ pupil dilation. Results are discussed in light of pupillometry evidence
