The perception of interpersonal distance is distorted by the Müller-Lyer illusion

Abstract There is growing interest in how human observers perceive social scenes containing multiple people. Interpersonal distance is a critical feature when appraising these scenes; proxemic cues are used by observers to infer whether two people are interacting, the nature of their relationship, a...
