A review of the literature indicates that several of the eyewitness issues exam-ined here have been studied in great detail by means of experimental methods: the effect of delay, cross versus own-race effects, weapon focus effects, and the relation between conﬁdence and accuracy. There is a generally accepted principle in the scientific community that memory fades relatively quickly and then continues to diminish with the passage of time. Sleep consistently strengthens and protects memory from interference, particularly when a recall test is used. 48 Although the delay between witnessing a crime and viewing an identification procedure in actual cases can be extensive, eyewitness identification … We review the evidence about delay, too, before introducing our ex-periments that examine both the initial delay between witnessing a crime and a first identification (ID), as well as the subsequent delay between … Eyewitness identification studies, however, are frequently executed within a single session of roughly 1 or 2 hours so the impairing effects of stress on memory retrieval may offset the known beneficial effects of stress and stress hormones on memory formation (Schwabe et al., 2012; Wolf, 2009). Experiment 1 attempted to disentangle these factors through systematic manipulations of the number of repeated lineups and the length of delay … Prior eyewitness research has examined the effects of repeated identification procedures and delays on eyewitness identification, but these studies have either confounded these two factors or studied them in isolation. delays on eyewitness identification, but these studies have either confounded these two factors or studied them in isolation. A large number of laboratory studies indicate This study investigated the use of event‐related brain potentials (ERPs) as a neurophysiological measure of eyewitness identification accuracy during a lineup task (ERP‐lineup). Eyewitness identifications during identification procedures such as show ups, live line ups and photo line ups are reliable to an extent in the forensic discipline, but are mostly fallible when assisting police with their enquiries regarding suspects and offenders, due to the fact that the reliability is dependent on a variety of factors … shorter delay (within a few seconds) ... Eyewitness identification accuracy, confidence and decision times in simulta-neous and sequential lineups. Stages in the Eyewitness Process There are three main stages of the eyewitness process : (i) perception of an event and the persons central to it, (ii) storage and assimilation of the information extracted from that experience, and (iii) remembering aspects of the experience and acting on it. Experiment 1 attempted to disentangle these factors through systematic manipulations of the number of repeated lineups and the length of delay between the original Increasing research shows that eyewitness confidence at the time of the initial identification can be a strong predictor of accuracy under appropriate lineup identification conditions. Inaccurate eyewitness identifications are the leading cause of known false convictions in the United States. longer delays are expected to lead to lower performance and more errors in eyewitness identification. Time delays Eyewitness identification … Time delay between viewing the crime and completing the ERP‐lineup (no‐delay, 1‐h delay and 1‐week delay conditions) and culprit … However, the effect of sleep on recognition memory is more equivocal. Moreover, improving eyewitness memory is difficult and often unsuccessful. Eyewitness Identification 1 .1 . 1 In such conditions, police show an eyewitness a lineup of faces that consists of a single suspect who does not stand out (i.e., a fair … Journal of Applied Psychology, 78, 22-33.
