以记忆项目自身信息作为提示线索的指向遗忘

Study of Directed Forgetting by Using Messages Related Item as Cues

与标准的指向遗忘研究不同,当实验设计学习项目自身具有的某种特征作为提示记住或遗忘的线索时,结果同样观察到指向遗忘效应。数据分析显示,知觉特征为线索时,自由回忆和再认测试都反映出指向遗忘效应;而语义特征为线索时,只有自由回忆测试反映出指向遗忘效应。另外,知觉线索条件产生的指向遗忘效应显著高于语义线索条件。结果支持强调编码过程的指向遗忘理论解释。

The experiment was designed to explore the effect of directed forgetting, by using messages related item as cues to indicate whether the presented item was a word to be forgotten （TBF） or to be remembered （TBR）. When the perceptual feature of the words was used as cue, both recall and recognition memory were better for TBR than for TBF words, but when the semantic feature of the words was used as cue, only recall memory was better for TBR than for TBF words. In addition to these findings, the effect of directed forgetting in perceptual condition was more than that in semantic condition.
