RATIONALE
Witnesses who discuss a crime together may report details that they did not see themselves but heard about from their co-witness. Co-witness information may have beneficial and harmful effects on memory accuracy depending on whether the information was correct or incorrect.
OBJECTIVES
Given the prevalence of intoxicated witnesses, it is imperative to understand how alcohol influences this effect.
METHODS
The present study asked pubgoers (n = 67) at varying levels of intoxication to recall a mock crime video after having also watched a video witness statement containing both correct and false information.
RESULTS
Increased intoxication was associated with decreased confidence, completeness and accuracy, but no increased tendency to report false information. Exposure to incorrect post-event information (PEI) can lead to the incorporation of incorrect information, whereas exposure to correct PEI increased accuracy, regardless of individuals' alcohol intoxication status.
CONCLUSIONS
Thus, whilst discussion and intoxication can negatively impact eyewitness memory, discussion may also have benefits for both sober and intoxicated witnesses.
理由
一起讨论犯罪的目击者可能会报告他们自己没有看到但从共同目击者那里听到的细节。根据信息是否正确，共同目击者的信息可能对记忆准确性产生有益和有害的影响。
目的
鉴于醉酒目击者的普遍性，了解酒精如何影响这种效应至关重要。
方法
本研究要求不同醉酒程度的酒吧顾客（n=67）在观看包含正确和错误信息的视频证人陈述后，回忆一段模拟犯罪视频。
结果
醉酒程度的增加与信心、完整性和准确性的降低有关，但没有增加报告错误信息的趋势。接触错误的事后信息（PEI）会导致错误信息的纳入，而接触正确的 PEI 会提高准确性，无论个体的酒精中毒状态如何。
结论
因此，虽然讨论和醉酒会对目击者的记忆产生负面影响，但讨论也可能对清醒和醉酒的目击者都有好处。
