Effect of Individual Differences in Fear and Anxiety on Face Perception of Human and Android Agents

Abstract

People process human faces configurally—as a Gestalt or integrated whole—but perceive objects in terms of their individual features. As a result, faces—but not objects—are more difficult to process when presented upside down versus upright. Previous research demonstrates that this inversion effect is not observed when recognizing previously seen android faces, suggesting they are processed more like objects, perhaps due to a lack of perceptual experience and/or motivation to recognize android faces. The current study aimed to determine whether negative emotions, particularly fear of androids, may lessen configural processing of android faces compared to human faces. While the current study replicated previous research showing a greater inversion effect for human compared to android faces, we did not find evidence that negative emotions—such as fear—towards androids influenced the face inversion effect. We discuss the implications of this study and opportunities for future research.
