On reporting recollective experiences and "direct access to memory systems"

Strack and Förster (1995) showed that, unlike remember responses, know responses in recognition memory were influenced by manipulating response bias. We describe an experiment that replicated theirs but additionally allowed subjects to report guesses. Only guess responses were influenced by this manipulation. Response bias had no effects on either know or remember responses. This outcome suggests that manipulating response bias influences know responses only when guessing is encouraged but not reported as such. Moreover, though know responses reflected memory for the study events, guess responses did not.
