How Does Cognitive Load Influence Recollection of True/False Information?

Presented by: Daria Niedziałkowska
Dual-recollection theory (Brainerd et al., 2015) has been recently successfully applied in the research on memory for truth and falsity (Niedziałkowska & Nieznański, 2021) showing better context recollection for truth than falsity. The theory recognizes two types of recollection (context and target) and a univariate process - familiarity. In the literature on the memory representation for truth and falsity, cognitive load manipulation has been applied to test competing models since they predict different effects of load on memory for true vs. false feedback. Consequently, we investigated how cognitive load affects the processes distinguished in the dual-recollection theory operating during the memory for truth and falsity task. Concurrent tasks used to introduce load aimed to impair one of the mechanisms of the maintenance of verbal information:(a) rehearsal, by asking participants to repeat syllables after each learned sentence or (b) refreshing, where choice-reaction task was implemented. Rehearsal and refreshing impairments are assumed to differ in their impact on recollection and familiarity processes (Abadie & Camos, 2019). The results showed better context recollection for truth comparing to falsity in the control and rehearsal-interference group. Moreover, context recollection for truth was better for control group, compared to both groups with cognitive load applied. In the no-load condition target recollection for truth was better than for falsity, and in the refreshing-interference condition target recollection for falsity was better compared to control group. Our results showed that cognitive load affects memory for truth/falsity mainly by reducing the contribution of context recollection to memory of truth feedback.
