Abstract

The explosion of research interest in faces and face processing and the engagement of a wide range of disciplines is fueled by theoretical fascination combined with applied importance. This article describes some of the psychological research that has accompanied the recent rapid development or deployment of systems for showing, building, or manipulating faces for a variety of purposes. It illustrates the psychological issues that arise in a range of engineering, medical, and legal contexts and shows that technological development has not always been matched by an appreciation of the psychological issues that need to be overcome to take full advantage of new systems. In some areas the advances raise new psychological issues. New technology has simply replicated old problems—e.g. that witnesses cannot recall individual face features; or that resemblance and identity are not the same thing.
