Abstract

Reinforcement values of facial expressions for visual fixation remain underdeveloped in extant literature, though numerous studies have investigated the function of facial expressions as antecedents of gaze behavior. This study used a concurrent gaze-contingent reinforcement procedure to compare reinforcement values of positive and negative facial expressions for gaze fixation. In total, 7 of the 20 typical adults fixated more frequently on the side that was followed by positive facial expressions. The results suggest that a novel application of eye tracking technology could allow for the evaluation and comparison of reinforcement values of social visual stimuli.
