Abstract
The Deese-Roediger-McDermott paradigm is an experimental manipulation that induces false memory creation (Deese, 1959; Roediger & McDermott, 1995). This study presented auditory DRM lists either in silence or in background noise to both young and older adult samples. Background noise significantly reduced participants' recall accuracy, F(1, 93) = 14.14, p < .001, ηp2 = .13, and false memory production, F(1, 93) = 4.02, p = .05, ηp2 = .04, but there were no significant differences between age groups. Moreover, older adults’ self-reported measures of cognitive load correlated with their accuracy, r(47) = –.39. No such relationship was observed in the younger adult group suggesting that, although both groups reached similar levels of performance, they likely approached the task differently. These findings also highlight the need for further examination into how individual differences mediate memory performance in the DRM, especially in older adults.
