语义联系强度和测验情境对错误记忆的影响

The Influence of Semantic Relation Strength and Situation of Testing on False Memory

本研究以关联程度不同的词表为实验材料在不同的测验情境中对错误记忆进行研究,采用2 × 2的混合实验设计,考察了被试内变量语义联系强度(强关联,弱关联)和被试间变量测验情境(关键诱饵所处的位置)对再认测验中关键诱饵的错误再认率的影响。结果发现:1) 语义联系强度主效应显著,测验情境的主效应显著,二者交互效应显著;2) 测验情境为关键诱饵紧跟在无关词后面的时候,词表语义关联强引发错误记忆的效果更好,且差异显著;3) 当语义关联强度弱的时候,关键诱饵紧跟在有关词后面更能引发错误记忆,且差异显著,上述结果表明语义联系强度和测验情境对错误记忆均有不同程度的影响。

In order to investigate false memory, this study took different degree of correlation of vocabulary as learning staff and tested at different situation. In the study, 2 × 2 mixed design of experiment is used to explore the influence of semantic relation strength (strong, weak) and situation of testing (the location of key baits) on error recognition rate of key baits. The results show that: 1) The main effect of semantic relation strength is significant, the main effect of testing situation is significant, and the interaction effect of the two is significant;2) When the key baits followed the irrelevant words, the strong semantic association of the word list has a better effect on false memory, and the difference is significant;3) When the semantic association strength is weak, the key baits following the relevant words is more likely to cause false memory, and the difference is significant. The above results show that the semantic relation strength and situation of testing have mutual effects on false memory.
