title: When believing is seeing: the effect of scripts on eyewitness memory.
abstract: Two studies examined the conditions under which event schema or scripts produce gap-filling errors in eyewitness accounts of a robbery. In Study 1, scripts for the robbery of a convenience store were identified. Results revealed high agreement among the 120 participants concerning the sequence of actions for such a robbery. Based on the information obtained in Study 1, participants in Study 2 (N = 144) viewed one of two sequences of slides depicting a robbery of a convenience store by a lone robber. In one sequence, three central script actions were omitted and in the other, three peripheral script actions were omitted. In addition, rate of exposure was varied (2 vs. 8 sec) as was the length of the retention interval (5 min vs. 1 week). As predicted, there was a higher rate of false recognition for central as opposed to peripheral actions, and this tendency was exaggerated for the longer retention interval. The theoretical and practical implications of the findings are discussed.
