This study compared the effects of fixed- and varied-context repetition on associative recognition in amnesia. Controls and amnesic participants were presented with a set of three-word phrases. Each was presented three times. In the varied-context condition, the verb changed with each presentation; in the fixed-context condition, it remained constant. At test, participants performed an associative-recognition task in which they were shown pairs of words from the study phase and asked to distinguish between intact and recombined pairs. For corrected recognition (hits – false alarms), controls performed better in the varied-context than in the fixed-context repetition condition, whereas amnesic participants’ performance did not differ between conditions. Similarly, controls had lower false-alarm rates in the varied-context condition, but there was no significant effect of condition for the amnesic participants. Thus, varied-context repetition does not improve amnesic participants’ performance on a recollection-dependent associative-recognition task, possibly because the amnesic participants were unable to take advantage of the additional cues that the varied-context encoding condition provided.
