Exemplar-based and Norm-based Models of Face Recognition
Abstract:This paper gives an overview of recent attempts to explore a heuristic for the representation of faces in memory. Valentine (1991a, 1991b) has described a framework whereby face representations may be thought of as locations within a multidimensional space. This framework has proven very efficient at accommodating and accounting for many of the phenomena observed in face recognition research. Valentine has proposed that there are at least two possible models which can be based on this framework: an exemplar-based model and a norm-based model. This discussion examines recent attempts to determine between these two accounts.
