Retrieval Mechanism

In the lexical decision task, the additive effects of stimulus quality and word frequency have been used to infer the presence of independent processing stages in visual word recognition. Importantly, this pattern can be moderated by semantic priming, suggesting the presence of a retrospective prime retrieval mechanism that is selectively engaged based on task context (i.e., utility of the primes). We examine the sensitivity of this mechanism in two lexical decision experiments that manipulate stimulus quality, word frequency, and semantic priming. Critically, we studied these joint effects when the proportion of related primes was set at .50 or .25. Results indicated that with a .50 relatedness proportion, a three-way interaction was obtained such that additivity between frequency and stimulus quality was found following related semantic primes, but an overadditive pattern was exhibited following unrelated primes. When the relatedness proportion was reduced to .25, this interaction was eliminated. Furthermore, relatedness proportion affected the magnitude of the stimulus quality by priming interaction but not the frequency by priming interaction. These results are interpreted within the context of a flexible lexical processer that adaptively engages processes in response to task context.

Two Factors

Two experiments are reported that examined the joint effects of word frequency and stimulus quality in the context of a lexical decision task. In the first experiment the interval between response to a stimulus and onset of the next stimulus was 0.8 sec, and the effect of the two factors was additive. In the second this interval was 3.3 sec, and the effect of reducing stimulus quality was greater for infrequent words than for frequent words. This is similar to the result of Norris (1984). The inability of current models of word recognition to explain this finding is discussed.
