On obtaining episodic priming in a lexical decision task following paired-associate learning.

In four experiments, subjects made lexical (word-nonword) decisions to target letter strings after studying paired associates. In this lexical decision test, word targets previously studied as response terms in the paired associates were preceded at a 150-ms and/or 950-ms stimulus onset asynchrony (SOA) by one of various subsets of the following six types of primes: (a) a neutral ({xxx} or {ready}) prime, (b) a semantically unrelated word prime episodically related to the target through its having been previously studied in the same pair, (c) a semantically related word prime previously studied in a pair with some other unrelated word, (d) a semantically unrelated word prime previously studied in a pair with some other unrelated word, (e) a nonstudied semantically related word prime, and (f) a nonstudied semantically unrelated word prime. At the 950-ms SOA, facilitation of lexical decisions produced by the episodically related primes was greater in test lists in which there were (a) no 150-ms SOA trials intermixed, (b) no previously studied semantically related primes, and (c) no studied nonword targets. At the 150-ms SOA, facilitation from episodic priming was greater in test lists in which there were (a) no semantically related primes and (b) all studied word targets and no studied nonword targets.
