How level of processing really influences awareness in recognition memory.

Abstract In yes/no and two - alternative forced - choice recognition tests, subjects reported one of three states of awareness when selecting each target: remembering, knowing, or guessing. A remember response indicated recollection of the target's occurrence in the study list. A know response indicated the target was familiar in the experimental context but not recollected. A guess response indicated the target was selected in the absence of either remembering or knowing. In Experiments 1 and 2, level of processing influenced remember responses but not know responses and, in Experiment 3, generating versus reading similarly influenced remember but not know responses. In each experiment, when subjects reported that they were guessing they showed no ability to discriminate targets from lures. These results show that remember/know findings generalize from yes/no to two - alternative forced - choice recognition and that knowing is dissociable from guessing. The results also provide no support for the hypothesis, based on an independence model of remembering and knowing, and some other apparently contradictory results, that variables that have large effects on remembering produce opposite effects on knowing. A meta - analysis of previous level - of - processing studies yielded evidence consistent with these conclusions. In recent studies we have been developing an experiential approach to memory and awareness (Gardiner Java, 1994; Richardson - Klavehn Richardson - Klavehn, Gardiner, (2) memory performance; and (3) awareness, especially subjects' awareness of what they are trying to do to meet the demands of the tasks they are given, and their awareness of memory for the particular items they may encounter when carrying out such tasks (Gardiner Richardson - Klavehn et al., 1996). Where recognition memory is concerned, subjects' awareness of memory for particular items they may encounter includes at least two discrete states: recollection, and feelings of familiarity in the absence of recollection. These states of awareness have been measured by remember and know responses (Gardiner, 1988; Tulving, 1985a), which have revealed many functional dissociations within overall recognition memory performance (for reviews, see Gardiner Rajaram Richardson - Klavehn et al., 1996). In Tulving's (1983, 1985a, 1985b) theory, remembering and knowing are associated respectively with retrieval from episodic and semantic memory systems, and it is assumed that the relation between these systems is one of inclusivity (or redundancy), in the sense that representation in the episodic system necessarily entails representation in the semantic system, but not vice versa. Remember and know responses are defined exclusively, but at the level of the responses the difference between exclusivity and inclusivity is only a matter of definition. In each case, know responses would be defined as familiarity in the absence of recollection, and, with inclusivity, remember responses would be defined as recollection and familiarity, not just recollection. But subjects would still experience the same two states of awareness, regardless of whether the responses define these states as having an inclusive or an exclusive relation. …
