Abstract: This study examined two hypotheses regarding the source of individual differences in Interrogative Suggestibility(IS): (i)differences in attention to task-relevant and task-irrelevant stimuli; (ii) differences in one or more memory processes, indexed by ERP old/new effects. Participants(N=405)were screened for extremely low and high suggestible individuals(N=97). ERPs elicited by pictures that related to ("old") and did not relate to ("new")the story were recorded. ERP old/new effects were examined at selected scalp regions of interest at 3 intervals post-stimulus. Attention-related ERP components by story-relevant pictures, story-irrelevant pictures, and irrelevant distractors were measured from midline electrodes. Differences in IS were reflected in late right prefrontal old/new differences, while differences in memory and task performance were reflected in early and middle latency old/new differences. Results supported an account of individual differences in IS as reflecting post-retrieval memory processes rather than attention processes.
