This thesis examines the role of interpersonal spacing in determining the visual appearance and emotional response to images of faces. We present new methods for isolating the distance-dependent perspective projection as a visual feature, while controlling for confounding variables such as emotional expression. In behavioral experiments, we demonstrate the relevance of viewing distance to implicit social judgments, notably trust behavior in which real money was at stake. Finally, we provide tools for classifying face images according to viewing distance, and manipulating face images to simulate their appearance at different distances and different levels of trustworthiness.
