Abstract
Naming of a pictured object is substantially facilitated when the name has recently been produced in response to a definition or read aloud. The first experiment shows this to be so when over one hundred trials have intervened, and when the subjects can name the pictures quickly and accurately in the absence of priming. The locus of the effect must be in lexicalization processes subsequent to picture identification and is unlikely to be mediated by recovery of an episodic trace. Two further experiments show that prior production of a homophone of the object's name is not an effective prime, (although slower responses are somewhat facilitated when the homophones are spelled the same). Hence the facilitation observed for repeated production of the same word cannot be associated with the repetition of the phonological form per se. We conclude that the facilitation must be associated with retrieval of the semantic specification or the process of mapping of that specification to its associated phonological representation.
