False recognition in the Deese/Roediger-McDermott (DRM) paradigm was assessed following manipulation of encoding context. Undergraduate students at Simon Fraser University participated. Experiment 1 replicates the DRM effect using 5-item lists; Experiment 2 demonstrates that a false recognition effect also occurs for 3-item lists specifically developed to later bias the encoding context of DRM lists used in Experiment 1. Experiment 3 investigates false memory upon manipulation of list context; participants studied 8-item lists, in which either the first or last 3 items (bias items) of the list were in a different context than the remaining 5 DRM items. Findings revealed no differences in false recognition due to encoding context. Two accounts of the DRM effect are discussed: the associative activation account, and the discrepancy-attribution hypothesis.
