词频和年级对FOK判断的影响 总被引:5,自引:0,他引:5
本实验以识记材料的词频高低和被试年级为自变量对被试元记忆监测的FOK(feeling of knowing)判断进行研究。实验采用Hart提出的RJR(回忆—FOK判断—标准测验 )的经典范式。结果表明 :被试的年级影响FOK判断等级和准确性 ,大学生的FOK判断等级和准确性均高于高一年级学生 ;识记材料词频影响FOK判断等级的高低 ,不影响FOK判断准确性 ,被试对高频词对的FOK判断等级高于对低频词对的FOK判断等级 ,但FOK判断准确性无明显差异。 相似文献

模糊再认(FR)判断—元记忆领域的新方法 总被引:2,自引:0,他引:2
Hart所开创的FOK研究范式表明,在记忆的提取阶段由客体水平的回忆能引起元水平FOK判断,但历来的研究都忽略了由再认也能引起一种元记忆判断,这就是“模糊再认判断”(即FR判断).本文论述了FR判断的概念,特性和研究方法并加以实验验证.FR判断发生在记忆提取阶段,有着与FOK判断同等重要的研究价值和相似的研究方法.FR研究范式给予元记忆研究以新的思想和方法. 相似文献

Metamemory processes and executive control may be related, given that both are frontally mediated. However, previous behavioural research has been limited in identifying common processes driving this somewhat weak relationship partly because they mostly relied upon global executive measures and composite scores of executive function (EF). The present study investigated the relationship between specific EFs (task shifting, interference resolution), working memory capacity and feeling-of-knowing (FOK) and confidence judgements (CONF) in an episodic memory task. We found that, of the EFs, only task-switching performance was correlated with FOK accuracy and proposed a shared mechanism that may be at play in both task-switching and FOK judgements. We also demonstrated that interference resolution and episodic memory measures were related, suggesting strategic influences on memory retrieval. Finally, we found a strong consistency in the strength and accuracy of FOK and CONF judgements, possibly due to retrieval-based mechanisms in both types of judgements. 相似文献

知道感(FOK)和不知道感(FOnK)的实验分离 总被引:2,自引:2,他引:0
新近的脑成像研究结果提示:“知道感”(FOK)与“不知道感”(FOnK)可能是由两种不同的认知与脑机制所实现的。尽管这一设想质疑了以往的知道感研究中对此二者不加区分的处理方法,但脑成像研究在本质上是一种相关研究,因而并不能提供因果性的推论。这项行为实验将加工深度对FOK和FOnK的影响分开来加以考察,结果发现:深度加工只能使FOK的预测准确性增加,但却不但不能使FOnK的预测准确性增加,反而会使之降低。上述结果在(1)被试内设计,(2)被试间设计,(3)排除熟悉性所导致的不确定的再认等三种情况下都成立。上述结果为知道感的“双过程假设”提供了来自行为研究的证据。 相似文献

The study focused on the cognitive determinants of the accuracy of feeling-of-knowing (FOK) judgments made on episodic memory information. An individual differences approach was used on a sample of healthy older adults assessed on an episodic FOK task and on several neuropsychological measures. At a global level of analysis of FOK accuracy, the contributions of four general cognitive processes--episodic memory, executive functioning, fluid intelligence and processing speed--were examined concurrently. Stepwise regression analyses showed that executive functioning accounted for the major part of variance on FOK accuracy, followed by a significant contribution of episodic memory. After controlling for executive and memory involvement, fluid intelligence and processing speed no longer accounted for significant variance. At a more detailed level of analysis of FOK accuracy, the contributions of three specific executive processes--shifting, updating and inhibition--were assessed. The results revealed shifting function as the primary executive process engaged in the production of accurate FOK judgments in episodic memory. Some hypotheses are put forward to better understand the central role of executive functioning in the production of accurate FOK judgments. 相似文献

该研究使用RJR研究范式,探讨内隐的可接近信息对FOK判断等级和判断准确性的影响。结果发现:FOK判断等级受内隐的可接近信息量的影响,二者呈非单调递增、递减的关系;FOK判断等级随内隐的可接近信息强度的增强而增高;FOK判断准确性随内隐的可接近信息量的增多而降低,并随内隐的可接近信息强度的增强而增高。 相似文献

元记忆监测与人格特征相互关系的实验研究 总被引:4,自引:0,他引:4
运用RJR标准程序,考察了元记忆监测与两种人格维度(内外向以及情绪性)的关系,结果表明:元记忆监测水平受到了人格自身优势倾向性及其行为定向性的影响,人格的内外向特点和情绪稳定性特点直接制约着元记忆监测的准确性和稳定性。据此认为元记忆能力的度量和开发,应充分考虑人格因素的影响。 相似文献
