本研究考察个体关于加工流畅性的信念对学习判断(Judgment of learning, 简称JOL)的影响, 探讨字体大小效应的产生机制。研究通过两个实验分别考察个体关于“字体大小影响加工流畅性” (实验1)以及“加工流畅性影响记忆效果” (实验2)等信念对字体大小效应的影响。结果发现: 1)当人们相信大字体更流畅(实验1)或者越流畅越好记(实验2)时, 他们在大字体项目上的JOL值显著高于小字体项目上的JOL值; 2)当人们相信小字体更流畅(实验1)或者流畅性与记忆无关(实验2)时, 他们在大字体和小字体项目上的JOL值无显著差异, 字体大小效应消失。上述结果表明, 个体关于加工流畅性的信念是字体大小效应产生的重要原因, 是人们进行学习判断的重要线索。 相似文献

流畅性是个体做学习判断（Judgements of Learning, JOLs）时的重要线索,主要包括加工流畅性和提取流畅性。实验采用联想字对作为实验材料,把做JOLs的时间分为即刻JOLs (Immediate:I)（学习完一个项目立即判断）,短时延迟JOLs（Delay condition: D1）和长时延迟JOLs（D2）,考察不同JOLs时间条件下,流畅性线索对学习不良儿童和一般儿童的JOLs的不同预测模式。被试为普通小学五年级学习不良和一般儿童各20名,结果发现,一般儿童在I条件下主要利用加工流畅性,在D条件下主要利用提取流畅性做JOLs,而学习不良儿童无论在I还是D条件下均主要利用提取流畅性线索做JOLs。加工流畅性在I条件下效度较高,提取流畅性在D条件下效度较高 相似文献

本研究采用3个实验考察编码强度对字体大小效应的影响,探讨由于知觉特征而引发的元认知错觉的内在产生机制(实验1)与有效的矫正措施(实验2和实验3)。结果发现:(1)大字体词语的知觉流畅性显著优于小字体,并且贝叶斯多层中介分析结果表明,知觉流畅性对字体大小效应起部分中介作用(实验1);(2)随着编码强度的增加,由字体大小引起的学习判断错觉逐渐消失(实验2和实验3)。以上结果表明,刺激的知觉特征(字体大小)对个体学习判断的影响,随编码强度激活线索的增加而逐渐减弱。这一结果为真实教学情境中提高学习者的编码强度,进而削弱学习判断对知觉特征线索的依赖,并准确地监测自身的学习进程提供了科学依据。 相似文献

目的:研究拟探讨知觉改变引起的难度和材料意义引起的真实难度导致的非流畅体验对元认知判断的影响;同时对比记住判断和遗忘判断的不同。方法:引入定向遗忘程序,让被试在"记住"条件下作学习判断,在"忘记"条件下作遗忘判断,考察两种不同难度对人们有意遗忘和识记能力的影响。结果:两种材料难度对预测判断和学习成绩有不同的影响,而且两个实验均表明学习判断值显著高于遗忘判断值。结论:知觉属性导致的表面难度引起的非流畅性不同于材料的真实难度引起的非流畅性体验,由真实难度引发的加工可能促使记忆更加深刻,同时,记住判断的准确性高于遗忘判断。 相似文献

目的:通过三个实验考查样例特征、流畅性和信念对类别学习及其元认知判断的影响。方法:实验1采用2(样例特征)×2(测试类型)的组内设计以检验样例特征的作用; 实验2采用2(样例特征)×2(测试类型)×2(流畅性)的组内设计以检验流畅性的作用; 实验3采用2(样例特征)×2(测试类型)×2(流畅性信念)的混合设计以检验信念对类别学习判断的作用。结果表明:样例特征影响学习成绩、类别学习判断和流畅感; 流畅性不会影响类别学习判断; 原理解释能够有效建立“关于流畅性的信念”,且“关于流畅性的信念”对类别学习判断起作用。即样例多样性和流畅性信念对类别学习判断起作用,支持信念假说。 相似文献

该研究针对Koriat和Dunlosky实验研究结果的不同,通过两个实验,进一步考察内外部线索对学习判断（judgment of learning,简称为JOL）的影响。被试为山东师大本科生63名。内部线索词对的语义联系,两种外部线索分别是呈现时间和呈现顺序。本研究结果表明：（1）无论在交替呈现还是区组呈现条件下,内部线索对JOL和回忆都产生了显著影响;（2）呈现顺序和呈现时间可能是两种不同类型的外部线索;（3）不同的内外部线索对JOL有不同的交互作用;（4）实验二中无意义词对先呈现组的JOL大于有意义词对先呈现组的JOL,这说明JOL可能存在“锚定效应”。 相似文献

知觉流畅性对判断和决策的影响 总被引：1，自引：0，他引：1
流畅性是个体对加工信息难易程度的一种主观体验, 它分为知觉流畅性、概念流畅性、提取流畅性等。研究者通过操纵刺激与背景的颜色对比度、刺激的字体类型、清晰程度等因素来控制知觉流畅性, 发现知觉流畅性会影响一系列判断和决策任务, 如命题真实性、类别判断、偏好、熟悉性等。知觉流畅性既可以作为判断的直接线索也可以通过选择不同线索和认知策略来间接影响判断和决策。 相似文献

主要探讨不同延时间隔和线索类型对遗忘元认知判断的影响。采用传统的学习判断任务,让被试学习40对无意义配对词,并告知随后进行测试,当呈现第一个词时,被试能够回忆与之配对的后一个词。让被试预测当延迟不同时间（5分钟、1天和1周）进行测试时,他们能够记住（学习判断）或者遗忘（遗忘判断）后一词的可能性。最后,要求被试回忆所有词对。结果发现延时间隔对学习判断和遗忘判断有相似的影响;学习判断的等级和相对准确性均高于遗忘判断,说明人们对记住和遗忘的线索很敏感;相比于学习判断,人们监测自己遗忘能力的信心不足。研究结果表明人们能够利用延时间隔和线索类型来预测未来的测验成绩,对遗忘的监测能力低于对记住的监测。 相似文献

Abstract— Recent work on judgment and decision making has focused on how people preferentially use cues, or pieces of relevant information, that are easy to access when making decisions. In this article, we discuss a framework for understanding the ways that cues become accessible. We begin by identifying two components of cues and show how these components can become accessible during different parts a decision process. We highlight evidence for the use of accessible information and discuss implications for future research on heuristics. 相似文献

ABSTRACTWords presented in larger font size are considered more memorable and rated with higher judgments of learning (JOLs). One explanation for this phenomenon is that people believe that font size affects memory. However, it is not clear why people hold this belief. One alternative is that font size represents importance, with larger fonts implying more relevant information. More important information is judged as more memorable and is, in fact, better remembered. In Experiments 1 and 2 we presented words in small (18 points) and extra-large font (250 points) and found higher JOLs and higher judgments of importance with extra-large fonts. A mediation analysis showed that importance accounted for 21–23% of the effect of font size on JOLs. In Experiment 3, we tested whether processing fluency was higher with the extra-large font. In a lexical decision task, participants were slower at detecting words and non-words with extra-large than small font, which is the opposite of what the processing fluency hypothesis predicts. This result shows that the font-size effect persists even in conditions in which perceived fluency should be lower. In sum, this research explained the belief that font size affects memory because words in larger fonts are considered more important. 相似文献

This study examined the Chinese name-pronunciation effect. The easy-to-pronounce and difficult-to-pronounce Chinese names were created using the same characters in order to control for visual perceptual and conceptual fluency. In Experiment 1, participants rated each name in terms of liking, electability as a state leader, income level, and baby name preference. An additional rating of prevalence was used to estimate familiarity. In Experiment 2, participants did not read the name aloud before rating and performed intentional recall and recognition tests. In both experiments, the easy-to-pronounce names were rated higher than difficult-to-pronounce names on liking. This effect generalized to judgments of electability and baby name preference but not to prevalence and income level. There were no differences in memory performances between the two types of names. Results are discussed in terms of the boundary condition of the name-pronunciation effect and the advantage of using Chinese names to study this effect. 相似文献

Processing fluency influences many types of judgments. Some metacognitive research suggests that the influence of processing fluency may be mediated by participants’ beliefs. The current study explores the influence of processing fluency and beliefs on ease-of-learning (EOL) judgments. In two experiments (Exp 1: n?=?94; Exp 2: n?=?146), participants made EOL judgments on 24 six-letter concrete nouns, presented in either a constant condition (high fluency) with upper-case letters (e.g., BUCKET) or an alternating condition (low fluency) with mixed upper- and lower-case letters (e.g., bUcKeT). After judging words individually, participants studied the words and completed a free recall test. Finally, participants indicated what condition they believed made the words more likely to be learned. Results show constant-condition words were judged as more likely to be learned than alternating condition words, but the difference varied with beliefs. Specifically, the difference was biggest when participants believed the constant condition made words more likely to be learned, followed by believing there was no difference, and then believing the alternating condition made words more likely to be learned. Thus, we showed that processing fluency has a direct effect on EOL judgments, but the effect is moderated by beliefs. 相似文献

学习判断是元认知判断的一种重要形式,是对未来回忆成绩的预测。重复学习判断中的低自信效应是一个有趣而反常的现象,指在重复学习测验中,学习判断往往低估了回忆成绩的增加,出现低自信的一种现象。目前,大部分实验证据支持重复学习判断中的低自信效应是普遍存在的,但也有一些实验结果表明该效应是受一定条件限制的。对于这种低自信效应的作用机制,研究者提出了不同的理论模型（如,锚定调整假说、记忆偏向消除理论、过去测验记忆的启发式假说等）进行了深入探讨。最后,文章还指出了此领域现有研究的局限和有待研究的问题 相似文献
