Many faces, a single rule.

Nineteen successfully published submissions contributed to this aim. Their findings suggest that faces are a special object category in many respects. In the Editorial, we aim at an integrated view of these contributions. Several papers link findings on different facial information processing abilities, and illuminate their relationships with other cognitive and socio-emotional ability domains in age heterogeneous samples. We will first give an overview of the papers published in the research topic, integrate their findings and derive conclusions for future life-span research on multiple components of face perception
