Bias in conceptual priming

Abstract

In recent years, Ratcliff, McKoon, and colleagues have argued that priming in perceptual implicit memory tests is the result of biases in information processing. Three experiments are presented that extend this framework to the conceptual implicit memory domain. Participants studied a list of words before receiving a set of general knowledge questions. For some questions, participants studied the correct answer; for others, they studied a similar but incorrect answer. Although study of a correct answer facilitated performance, study of the similar alternative hurt performance. Costs and benefits of previous study were observed in both production and forced-choice tasks. However, there was no benefit of previous study when participants studied both the correct answer and the similar but incorrect alternative. The pattern of results indicates that participants were biased to respond with previously studied words on the conceptual implicit memory test. This pattern is concordant with the biased information-processing approach to priming.
