title: Verbal description benefits for faces when description conditions are unknown a priori.
abstract: Some prior research has shown a benefit for describing nonverbal study stimuli, particularly faces, on a later recognition test relative to a control (no description) condition. In such studies, participants have known a priori whether a stimulus will need to be described, meaning that encoding differences other than the description could account for the effect. In Experiment 1, a description benefit was obtained for faces that could not be attributed to encoding differences. A direct manipulation of description duration, thus allowing more time to produce descriptors, did not influence the description effect. In Experiment 2, visual rehearsal instructions (without any verbal descriptions) failed to produce a rehearsal benefit. The experiments provide direct evidence against an account where the description or rehearsal enhances the featural information of nonverbal representations. For the present results, a benefit stemming from the encoding and retrieval of descriptors appears to be an attractive theoretical alternative over one that posits an enhancement or alteration of featural or holistic information.
