Inversion Reduces Sensitivity to Complex Emotions in Eye Regions

Inferring humans’ complex emotions is challenging but can be done with surprisingly limited emotion signals, including merely the eyes alone. Here, we test for a role of lower-level perceptual processes involved in such sensitivity using the well-validated Reading the Mind in the Eyes task. Over three experiments, we manipulated configural processing to show that it contributes to sensitivity to complex emotion from human eye regions. Specifically, inversion, a well-established manipulation affecting configural processing, undermined sensitivity to complex emotions in eye regions (Experiments 1-3). Inversion extended to undermine sensitivity to nonmentalistic information from human eye regions (gender; Experiment 2) but did not extend to affect sensitivity to attributes of nonhuman animals (Experiment 3). Taken together, the current findings provide evidence for the novel hypothesis that configural processing facilitates sensitivity to complex emotions conveyed by the eyes via the broader extraction of socially relevant information.
