最近的研究表明，要求个人对以前见过的面孔进行口头描述可能会阻碍随后的识别尝试。这种现象，被称为“言语遮蔽”，已经在面孔识别范式中得到了相当广泛的研究;然而，研究并不总是复制一般的效果。基于对该现象的实际和理论兴趣，对29个效应量比较（N = 2018）进行了荟萃分析。在整个样本的研究有一个小的，但显着的，负效应（费舍尔的Z（r）= -0.12），表明一定程度的语言障碍或遮蔽，几个调节变量的固定效应分析表明，后描述延迟和类型的描述指令的显着影响。的模式的手段表明，遮蔽效应更容易发生时，立即识别任务的描述任务，当参与者被赋予一个精心的，而不是一个标准的（自由回忆），在描述任务的指令。在文献中的instruments进行了讨论，以及各种理论和应用问题的言语遮蔽效果。版权所有（C）2001约翰威利父子有限公司
Recent studies have demonstrated that requesting individuals to produce a verbal description of a previously seen face can hinder subsequent attempts at identification. This phenomenon, termed 'verbal overshadowing', has been studied rather extensively in the face-ide nti fi cation paradigm; however, studies have not always replicated the general effect. Based upon both practical and theoretical interests in the phenomenon, a meta-analysis of 29 effect size comparisons (N = 2018) was conducted. Across the sample of studies there was a small, yet significant, negative effect (Fisher's Z(r) = -0.12), indicating some degree of verbal impairment or overshadowing, A fixed-effects analysis of several moderating variables demonstrated a significant effect of post-description delay and type of description instruction. The pattern of means indicated that overshadowing effects were more likely to occur when the identification task immediately followed the description task, and when participants were given an elaborative, as opposed to a standard (free recall), instruction during the description task. Inconsistencies in the literature are discussed, as well as various theoretical and applied issues regarding the verbal overshadowing effect. Copyright (C) 2001 John Wiley & Sons, Ltd.
