The reliability of eyewitness testimony has become a popular research topic in applied and social psychology since Loftus and Palmer’s study in 1974 (see Steblay, 1997; Wright & Loftus, 1998; Deffenbacher, Bornstein, Penrod, & McGorty, for reviews). Participants viewed videos or slides of traffic accidents (Loftus & Palmer, 1974) or a criminal act (Roediger, Jacoby, McDermott, 1996; Cutler, Penrod, & Martens, 1987) and afterwards were asked several questions about what they had just seen. The manipulation in studies was that the researchers did not ask the same question to all participant, but instead changed the wording of one critical detail in the question. In Loftus and Palmer’s study, some of the subjects were asked “About how fast …show more content…

However, “discussion among victims or witnesses to a crime is difficult, if not impossible to prevent’’ (Yarmey, 1992, p. 252). The concern that witnesses might talk to each other has been confirmed by a survey conducted in Australia (Paterson & Kemp, 2006). They found that if the respondent had witnessed a serious event and there was a co-witness present, 86% of the respondents had discussed the witnessed event together, of which 63% percent had done so immediately after the witnessed event. In another survey by Paterson and Kemp (2005), police officers confirmed the observation that co-witnesses frequently discuss the witnessed event together, and also indicated that such discussions are difficult to prevent. Discussion between eyewitnesses seems inevitable, and several researchers have emphasized the negative effects of discussion on group memory, such as memory distortion, (Basden, Basden, Bryner, & Thomas 1997; Weldon, Bellinger, 1997), or memory conformity (Wright & Schwartz, 2008; French, Garry, & Mori, 2008) that occurs due to the group process. Whereas the first refers to the effect that an individual’s memory is altered by new information, the second refers to the phenomenon of someone’s memory being altered as a result of the influence of other people’s memories On the other hand, little research has been conducted regarding the possible positive effects of discussion on eyewitness memory recall.
