Guessing Strategies in Perceptual Identification: A Reply to McKoon and Ratcliff

Light and Kennison (this issue) found that bias effects in the forced-choice perceptual identification of words occurred only in a subset of participants, those who claimed on a strategy questionnaire to be deliberately guessing words they had studied previously. McKoon and Ratcliff (this issue) raised a number of objections to the proposal that bias effects are due to guessing strategies, citing difficulties in our statistical treatment of data, our use of subjective reports to classify participants, and our approach to the general problem of separating implicit from explicit influences on performance. This article responds to these objections.
