学习判断是元认知判断的一种重要形式,是指被试对其后测成绩的预测.准确性是学习判断研究的重要问题.学习判断准确性分为绝对准确性和相对准确性.本文重点介绍相对准确性的传统研究方法和修正方法,即预测前回忆和监测法.在比较两种相对准确性的研究方法在数据的收集和分析上的差别,提出传统方法在数据收集过程中只能通过假设推断学习判断判断前的提取过程,修正方法在数据收集时,在学习判断前插入一个回忆阶段,可以监测学习判断判断前的提取过程.应用修正方法使研究者既可分解总的准确性,又可通过加权平均数的算法合成总的准确性.因此该方法有助于研究者更加深入、精确地研究学习判断以及其他元认知判断问题. 相似文献

The three algorithms most frequently selected by behavior‐analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with criterion records to determine observer accuracy. Block‐by‐block and exact agreement algorithms were susceptible to inflated agreement and accuracy estimates at lower rates and durations. The exact agreement method appeared to be overly stringent for recording responding at higher rates (23.5 responses per minute) and for higher relative duration (72% of session). Time‐window analysis appeared to inflate accuracy assessment at relatively high but not at low response rate and duration (4.8 responses per minute and 8% of session, respectively). 相似文献

以汉字再认任务为载体, 采用两因素被试内设计, 考察任务所导致的心理负荷水平, 以及学习判断(JOL)和信心判断(JOC)两种监测方式, 对元记忆监测效果的影响。对监测效果的衡量分别使用了相对准确性, 绝对准确性, 以及判断偏差三种指标。结果发现, 个体在任务过程中的心理负荷水平会影响其对任务解决过程的监测准确性:心理负荷水平越高, 元记忆监测的准确性越低。心理负荷水平还会影响元记忆监测的判断偏差:心理负荷处于中等偏低水平时, 监测不容易出现偏差;心理负荷处于中等偏高水平时, 个体表现出过高自信;但当心理负荷达到较高水平后, 判断偏差消失;随着心理负荷水平继续增大, 个体又表现出过低自信。 相似文献

ABSTRACT— People's judgments about how well they have learned and comprehended text materials can be important for effectively regulating learning, but only if those judgments are accurate. Over two decades of research examining judgments of text learning—or metacomprehension —has consistently demonstrated that people's judgment accuracy is quite poor. We review recent research that has shown some success in improving judgment accuracy and then argue that the most common method used to investigate metacomprehension accuracy may inadvertently constrain it. We describe a new method that sidesteps some problems of the older method and present evidence showing how people can achieve high levels of metacomprehension accuracy. 相似文献

The production of complex sequences like music or speech requires the rapid and temporally precise production of events (e.g., notes and chords), often at fast rates. Memory retrieval in these circumstances may rely on the simultaneous activation of both the current event and the surrounding context (Lashley, 1951). We describe an extension to a model of incremental retrieval in sequence production (Palmer & Pfordresher, 2003) that incorporates this logic to predict overall error rates and speed-accuracy trade-offs, as well as types of serial ordering errors. The model-assumes that retrieval of the current event is influenced by activations of surrounding events. Activations of surrounding events increase over time, such that both the accessibility of distant events and overall accuracy increases at slower production rates. The model's predictions were tested in an experiment in which pianists performed unfamiliar music at 8 different tempi. Model fits to speed-accuracy data and to serial ordering errors support model predictions. Parameter fits to individual data further suggest that working memory contributes to the retrieval of serial order and overall accuracy is influenced in addition by motor dexterity and domain-specific skill. 相似文献

This study explores the importance of anticipated group discussion, the consensus decision rule, and rater motivation in determining how well rater teams identify ratee behaviors, i.e., behavioral accuracy. Results, based on 382 raters in 111 teams, suggest that the anticipation of group discussion can improve behavioral accuracy, but it appears that the benefits of discussion-only teams are limited to this anticipation effect. Furthermore, it also appears that rater motivation plays an important role in this type of team. Rater teams required to reach consensus, however, appear to show improved behavioral accuracy, regardless of whether raters can anticipate the consensus discussion and regardless of rater motivation levels. Implications, especially for assessment centers, are discussed. 相似文献

Study 1 expands upon previous research by looking at the ability of untrained raters to detect pathological traits within a normal population of college students. In Study 1, 30-s video clips of 81 target persons were shown to 42 raters. Ratings of traits of personality disorders made by thin slice raters reliably predicted scores on the personality pathology measures obtained from the targets themselves and from close peers. Study 2 is a preliminary examination of how pathological rater traits impacts thin slice accuracy. In Study 2, peer and self-report data were examined regarding 87 thin slice raters. Raters who exhibited traits of narcissistic personality disorder were significantly less accurate in making personality predictions regarding targets. Three clusters of personality items were identified based on rater characteristics related to accuracy in predicting behavior. 相似文献

In this study, using a single-case multiple-treatment reversal (A-B-A-B-C) research design, we replicated and extended previous
strategic self-monitoring research by teaching five students, with and without disabilities, to use ACT-REACT to increase
their academic engagement, productivity, and accuracy across new and previously learned math material. Then, we gradually
faded the students’ use of the strategic self-monitoring recording sheet until they were no longer using it. When the ACT-REACT
self-monitoring recording sheet was in place the students’ engagement and academic productivity increased; however, when it
was faded, the results varied. During fading, the students’ performance generally exceeded baseline conditions and compared
adequately to intervention effects. Overall, the results of this study support the advantages of strategic self-monitoring
and also point to the mixed benefits of fading these procedures in inclusive environments. 相似文献

FOK判断与可接近信息之间的关系 总被引:6,自引:0,他引:6
通过三个实验,用语义联想集大小不同的中文单字词研究了靶项目联想集的大小与FOK判断等级和准确性的关系。实验一通过两种不同联想集大小的靶子,比较外显的、提取出的信息和内隐的、语义网络中固有的被激活信息量对FOK判断等级和FOK判断准确性是否有不同的影响。实验二和实验三通过不同的靶子呈现时间和学习遍数,比较不同的识记强度对不同大小联想集的靶子的FOK判断等级和FOK判断准确性的影响。实验结果表明:FOK判断等级随外显的、提取出的信息总量的增多而增高,随内隐的、语义网络中固有的被激活信息量的增多而降低。FOK判断准确性随靶子本身的激活强度的增强而增高,随内隐的、语义网络中固有的被激活信息的激活强度的增强而降低,FOK判断准确性取决于这两种激活强度的综合作用。 相似文献
