两个实验考察了240名大学生在近似于日常判断情境中的记忆要求条件下对事件协变的判断能力。学生被要求记录事件频率，因为他们提出的（实验I），估计频率信息的记忆（实验I和II），或估计频率的事件组合和干扰线索的记忆（实验II）。在这些条件下的协变判断的比较表明，随着记忆需求的增加，判断准确性恶化。进一步的分析表明，记忆效应是由于对事件/状态组合频率的回忆不佳，以及倾向于转向更简单但不太准确的判断策略。它的结论是，在日常设置中的事件关系的识别很可能是一个充满错误的过程。(28参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Two experiments investigated 240 undergraduates' competence at judging event covariations under conditions approximating the memory demands found in everyday judgment settings. Ss were presented with sequences of individual event/state combinations and were asked either to record the event frequencies as they were presented (Exp I), to estimate the frequency information from memory (Exps I and II), or to estimate frequencies of event combinations and distractor cues from memory (Exp II). Comparisons of covariation judgment in these conditions showed that judgment accuracy deteriorated as memory demands increased. Further analyses suggested that the memory effect was due to poor recall of the frequency of event/state combinations and to a tendency to shift to simpler but less accurate judgment strategies. It is concluded that identification of event relationships in everyday settings is likely to be an error-ridden process.(28 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
