The notion of constructive memory processes is imported from research on eyewitness memory to the area of social cognition. Mere questioning about the applicability of personality attributes to a target person is shown to affect subsequent memory-based judgements of that person. These constructive influences are to be distinguished, conceptually, from the global notion of priming effects. In Expt 1, the target person was first described as an extravert; afterwards, subjects had to indicate whether either desirable aspects of extraversion (self-confidence) or undesirable aspects (exhibitionism) apply to the target or not. Mere questioning resulted in a congruent judgment bias towards the questioned attributes that did not generalize to a global halo effect. Experiment 2 replicated the basic finding and demonstrated that this phenomenon is independent of a generation effect (i.e. the memory advantage of self-generated inferences). These results are interpreted in terms of (a) a reframing of the categorical distribution representing the information about the target person in memory and (b) a regressive tendency to assume intermediate default values rather than extreme values for questioned attributes under uncertainty. Alternative explanations in terms of demand effects or a conformation bias cannot provide sufficient accounts. The relevance of constructive processes to understanding self-fulfilling prophecies and other phenomena in social interaction is discussed.
建构性记忆过程的概念是从目击证人记忆研究引入到社会认知领域的。仅仅是关于人格特质适用于目标人物的询问就被证明会影响随后基于记忆对该人物的判断。从概念上讲,这些建构性影响与启动效应的整体概念是有区别的。在实验1中,目标人物首先被描述为外向者;之后,受试者必须指出外向性的积极方面(自信)或消极方面(爱出风头)是否适用于目标人物。仅仅是询问就导致了对所询问特质的一致性判断偏差,但这种偏差并没有泛化为整体的晕轮效应。实验2重复了这一基本发现,并表明这种现象与生成效应(即自我生成推理的记忆优势)无关。这些结果可以从以下两个方面来解释:(a)对记忆中代表目标人物信息的类别分布进行重新构建;(b)在不确定性下,对于所询问特质倾向于假设中间默认值而非极端值的回归趋势。从需求效应或证实偏差角度的其他解释都不足以说明问题。本文还讨论了建构性过程对于理解自我实现预言及社会互动中其他现象的相关性。
