个体关于加工流畅性的信念对字体大小效应的影响

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。     

自定步调学习时间的习惯性反应：来自眼动的证据

习惯性反应指学习者根据自身阅读习惯来进行学习时间分配,它通常由词对位置这一外部线索激发。研究运用眼动记录技术,采用Metcalfe范式探讨词对位置和难度对学习时间分配的影响,以检验自定步调学习时间的习惯性反应。结果发现：（1）在自定步调总学习时间上,学习者倾向于对难度越大的项目分配越多的学习时间;（2）在前期自定步调学习进程上,当词对位置为易-中-难条件时,学习者倾向于优先在容易项目上分配较多的学习时间,接着是中等难度项目,最后是困难项目;当词对位置为难-中-易条件时,结果相反。这说明学习者的自定步调总学习时间受项目难度驱动,而前期自定步调学习时间受习惯性反应影响。     

编码后奖赏影响基于议程的学习：奖赏预期和结果的作用

基于ABR模型考察奖赏预期和奖赏结果对不同难度词对记忆与元记忆的影响。结果发现：(1)限时学习条件下,奖赏结果促进不同难度词对记忆成绩和学习判断,奖赏预期仅提高简单词对的记忆成绩。(2)自定步调学习条件下,定时学习判断时奖赏结果仅影响学习判断;奖赏预期促进高难度词对的学习时间分配,从而提高记忆成绩和学习判断。(3)在自定步调学习时,奖赏预期超越难度成为影响学习时间分配的因素。以上结果表明,个体会综合奖赏预期、奖赏结果和难度构建学习议程,足够大的奖赏预期会超越难度成为议程构建的主导因素。但奖赏预期和奖赏结果对记忆成绩、学习时间分配和学习判断的影响受学习条件调节。     

议程与习惯性反应对学习时间分配的影响：来自眼动的证据

采用眼动记录技术,操作三种词对位置,探讨议程与习惯性反应对学习时间分配的影响。实验一设置无时间限制条件,结果发现,20名大学生被试均优先选择左边的项目,项目的自定步调学习时间不存在词对位置效应。结果表明,被试的习惯性反应影响项目选择,不影响自定步调学习时间。实验二设置有时间限制条件,结果发现,20名大学生被试均优先选择容易项目并分配更多的时间学习容易项目,且容易项目的选择存在词对位置效应。结果表明,议程驱动主导被试的项目选择和自定步调学习时间,但不能完全消除习惯性反应对项目选择的影响。     

学习判断的框架效应：加工流畅性的影响

研究旨在考察学习判断中的框架效应以及加工流畅性的影响。采用逐项即时学习判断任务,通过操纵指导语来设置正向框架和负性框架。其中,实验1和实验2分别考察低、高相关词对学习任务中学习判断的框架效应。实验3深入探究了提取流畅性对学习判断框架效应的影响。研究结果显示:第一,在高加工流畅性词对的学习判断上出现了框架效应;第二,提取流畅性不影响学习判断的框架效应。研究支持了消极心理锚点假说,并推测编码流畅性是产生框架效应的主要因素。     

不同学习目标条件下学习时间分配的习惯性反应

采用眼动记录技术,探讨不同学习目标条件下词对位置对学习时间分配的影响。实验结果发现：在高学习目标条件下,词对位置对项目选择存在显著影响,对自定步调学习时间不存在显著影响;在低学习目标下,词对位置对项目选择和自定步调学习时间均不存在显著影响。表明议程驱动和习惯性反应是影响学习时间分配的两种认知机制,学习者会根据学习情境采用议程驱动或习惯性反应来有效地进行学习时间分配,以最小的努力实现学习目标。     

编码强度对字体大小效应的影响

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。     

词频和运动流畅性对学习判断的影响：多线索整合的视角

本研究探讨基于经验的运动流畅性和基于理论的词频对学习判断的影响以及二者可能存在的相互作用,探讨非分析性加工和分析性加工在元认知监测中的作用模式。结果显示：（1）运动流畅性和词频均会影响JOL;（2）运动流畅性对JOL的影响会因为词频的变化而改变,而在认知负荷条件下,词频对JOL的影响还会因为运动流畅性的变化而不同。研究结果支持JOL中的运动流畅性效应与词频效应,也表明分析性和非分析性加工在JOL中会共同发挥作用。

加工流畅性和提取流畅性与学习不良儿童学习判断的关系

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     

Separation of encoding fluency and item difficulty effects on judgements of learning

The fluency of information encoding has frequently been discussed as a major determinant of predicted memory performance indicated by judgements of learning (JOLs). Previous studies established encoding fluency effects on JOLs. However, it is largely unknown whether fluency takes effect above and beyond the effects of item difficulty. We therefore tested whether encoding fluency still affects JOLs when numerous additional cues indicating the difficulty of an item are available as well. In three experiments, participants made JOLs for another participant while observing his or her self-paced study phase. However, study times were swapped in one experimental condition, so that items with short study times (indicating high fluency) were presented for long durations, whereas items with long study times (indicating low fluency) were presented for short durations. Results showed that both item difficulty and encoding fluency affected JOLs. Thus, encoding fluency in itself is indeed an important cue for JOLs that does not become redundant when difficulty information is available in addition. This observation lends considerable support to the ease-of-processing hypothesis.     

Judgments of learning reflect encoding fluency: conclusive evidence for the ease-of-processing hypothesis

According to the ease-of-processing hypothesis, judgments of learning (JOLs) rely on the ease with which items are committed to memory during encoding--that is, encoding fluency. Conclusive evidence for this hypothesis does not yet exist because encoding fluency and item difficulty have been confounded in all previous studies. To disentangle the effects of encoding fluency and item difficulty on JOLs, we used a variant of the learner-observer-judge method in which participants observed the study phase of another participant and indicated his or her JOLs. At the same time, the to-be-studied word pairs were concealed by strings of symbols. Our experiment revealed that participants use self-paced study time as a cue for JOLs when they themselves have studied and recalled word pairs before. This metacognitive monitoring of study time provides strong support for the ease-of-processing hypothesis.     

知觉流畅性对判断和决策的影响

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。     

Easy comes,easy goes? The link between learning and remembering and its exploitation in metacognition

The cue-utilization view in metacognition assumes that judgments of learning (JOLs) are based on inferences from mnemonic cues deriving from the online processing of items during learning. This view calls for a specification of the underlying heuristics, their validity in predicting memory performance, and the extent to which they are utilized. This study examines one such heuristic: easily learned, easily remembered (ELER). We first show that ease of learning, as indexed by self-paced study time and by the number of trials to acquisition, is indeed a valid cue for recall success. We then demonstrate that this correlation between learning and rememberingunderlies metacognitive predictions about the future recallability of different items. The results are discussed in terms of the idea that metacognitive judgments incorporate knowledge about the internal ecology of cognitive processes, much as the perception of the external world embodies knowledge about the ecological structure of the environment.     

样例多样性和流畅性信念对类别学习判断的影响

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。     

Words in larger font are perceived as more important: explaining the belief that font size affects memory

ABSTRACT

Words 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.     

The effects of list composition and perceptual fluency on judgments of learning (JOLs)

The perceptual fluency hypothesis proposes that items that are easier to perceive at study will be given higher memorability ratings, as compared with less fluent items. However, prior research has examined this metamemorial cue primarily using mixed-list designs. Furthermore, certain memory effects are moderated by the design (mixed list vs. pure list) used to present stimuli. The present study utilized mixed as well as pure lists to assess whether judgments of learning based on perceptual fluency are relative or absolute and whether people are sensitive to differences in recall produced by variation in list composition. Using font size and generation manipulations, Experiments 1 and 2 showed that the effect of perceptual fluency on metamemory is relative in nature, occurring only in mixed lists. Experiments 2 and 3 revealed that metamemory is insensitive to the effect of list composition on recall. These findings are consistent with the assumptions of Koriat’s (Journal of Experimental Psychology: General 126: 349-370, 1997) cue-utilization framework, that JOLs reflect a comparative process and are insensitive to cues pertaining to conditions of learning.     

Easy on the mind, easy on the wrongdoer: Discrepantly fluent violations are deemed less morally wrong

The present experiment tested the hypothesis that discrepancies in processing fluency influence the perceived wrongness of moral violations. Participants were presented with numerous moral violations in easy or difficult to read font. For some violations experienced perceptual fluency was consistent with the fluency associated with previous violations, whereas for others it was more fluent or more disfluent. Results show that, across multiple vignettes, participants rated moral violations that were processed with discrepant fluency as less morally wrong than those processed with discrepant disfluency. The current work highlights the importance of metacognitive experiences in moral judgment and contributes to the emerging literature on the role of experiential factors in moral judgment.
