Abstract:
Three lexical decision experiments examined the conditions in which nonwords activate semantics. Lexical decisions to targets (e.g., CAT) were faster when preceded by semantically related nonword primes (e.g., DEG derived from DOG) when the prime was brief and masked; this nonword priming effect was eliminated when the prime was presented for a longer duration. These results are discussed in the context of both parallel distributed processing models and the idea that the occurrence of nonword priming depends upon subjects being unable to verify the identity of the prime.
