The prime lexicality effect: form-priming as a function of prime awareness, lexical status, and discrimination difficulty.

G. W. Humphreys, D. Besner, and P. T. Quinlan (1988) found that form-primes (e.g., contrast-CONTRACT) were effective only with masked primes. C. Veres (1986) obtained the same effect for word primes but found that nonword primes (e.g., controct) were effective regardless of masking. In a lexical-decision task, the present study failed to find any priming with word primes but only when the nonword distractors were very close to a particular word (e.g., UNIVORSE). With more distant nonword distractors (e.g., ANIVORSE), priming with word primes was restored in the masked condition. In terms of an entry-opening model of priming, this effect was interpreted as a blocking of priming by a postaccess checking operation. Alternatively, in an interactive activation model, this effect could be modeled either by decreasing the strength of lexical competition or by changing the decision criterion from local to global activation.
