Preserving Informational Separability and Violating Decisional Separability in Facial Perception and Recognition.

Abstract

The holistic encoding hypothesis (M. J. Farah, K. D. Wilson, M. Drain, & J. N. Tanaka, 1998) proposes that faces are encoded and used in perception and cognition as relatively undifferentiated wholes. A previous study (M. J. Wenger & E. M. Ingvalson, 2002) found very little support for the strong version of this hypothesis and instead found evidence that shifts in decisional criteria may be important. This study provides a replication and stronger test of those findings, demonstrating consistent violations of decisional separability and preservation of informational separability in both immediate perception and delayed recognition.
