Memory influences subjective experience: Noise judgments.

The influence of memory on the subjective experience of later events was investigated in two experiments. In one experiment, previously heard sentences and new sentences were presented against a background of white noise that varied in intensity. In a second experiment, a cue set of words was presented either before or after a target set that was embedded in noise. The cue set was either the same as or different from the target set. In both experiments, one of the tasks was to judge the loudness of the noise. The data show that subjects were unable to discount the contribution of memory to perception when judging the noise level. Subjects appeared to base their noise judgments on ease of interpretation of the message presented through noise, with differences in ease being misattributed to a difference in noise level. The advantages of subjective experience as a measure of memory, and the role of subjective experience and misattribution in confusions between cognitive and physical deficits are discussed.
