The current study was a preliminary investigation that aimed to compare the performance of eyewitnesses with and without a brain injury on two target-absent line-up procedures: a simultaneous procedure and a sequential procedure with confidence ratings. A 2 × 2 design ( = 25) was employed, where both brain-injured ( = 15) and non-brain-injured ( = 10) participants were shown a short video of a non-violent crime taking place before taking part in either a simultaneous or sequential target-absent line-up. Participants' general cognitive abilities and memory recall accuracy were also measured. Results found no significant differences in false identification rates between brain-injured and non-brain-injured witnesses. It was also found that participants with a greater memory accuracy were in fact more likely to make a false identification. The implications and limitations of the study are discussed.
本研究是一项初步调查，旨在比较有脑损伤和无脑损伤的目击者在两种无目标列队辨认程序中的表现：同时呈现辨认程序和带有信心评级的顺序呈现辨认程序。采用了2×2设计（n = 25），让脑损伤参与者（n = 15）和无脑损伤参与者（n = 10）在参与同时呈现或顺序呈现的无目标列队辨认之前，观看一段非暴力犯罪发生的短视频。还测量了参与者的一般认知能力和记忆回忆准确性。结果发现，脑损伤目击者和无脑损伤目击者在错误辨认率上没有显著差异。研究还发现，记忆准确性较高的参与者实际上更有可能做出错误辨认。文中讨论了该研究的意义和局限性。
