Allocation of self-paced study time and the "labor-in-vain effect"

This research explored the possibility that a metacognitive control process (namely, the allocation of self-paced study time) might be affected by the output from metacognitive monitoring processes (i.e., ease-of-learning and/or feeling-of-knowing judgments). In three experiments, university undergraduates received instructions that emphasized either accuracy of learning or speed of learning. The major findings were: (a) ease-of-learning judgments and feeling-of-knowing judgments are reliably related to study-time allocation, with more self-paced study time being allocated to the supposedly more difficult items; (b) even when instructed to master every item and when allowed unlimited study time to do so, people terminate study before learning is completed; and (c) large increases in self-paced study time can yield little or no increase in the subsequent likelihood of recall (the "labor-in-vain effect"). Implications are drawn for a model of the interplay between metacognitive monitoring processes and metacognitive control processes.     

学习判断与学习时间分配的关系

学习判断与学习时间分配的关系是元认知领域的重要问题, 对学习判断的研究在于使个体了解自己的学习和记忆活动, 从而有效控制学习过程, 合理分配学习时间, 这是元记忆监测影响控制的典型例子。近来有研究者提出学习时间分配不仅表现控制功能, 而且还表现监测功能。于是围绕学习时间的双重功能, 他们提出了元记忆监测与控制至少存在两种关系模型—— MC(监测影响控制)模型和CM(控制影响监测)模型, 后来又提出了两模型相互协同作用的合并动态模型—— 连续波浪型模式和同时发生模型。未来的研究应在继续验证MC模型和完善CM模型的基础上, 尝试检验两模型的合并动态模型。     

Adaptive and qualitative changes in encoding strategy with experience: evidence from the test-expectancy paradigm

Three experiments demonstrated learners' abilities to adaptively and qualitatively accommodate their encoding strategies to the demands of an upcoming test. Stimuli were word pairs. In Experiment 1, test expectancy was induced for either cued recall (of targets given cues) or free recall (of targets only) across 4 study-test cycles of the same test format, followed by a final critical cycle featuring either the expected or the unexpected test format. For final tests of both cued and free recall, participants who had expected that test format outperformed those who had not. This disordinal interaction, supported by recognition and self-report data, demonstrated not mere differences in effort based on anticipated test difficulty, but rather qualitative and appropriate differences in encoding strategies based on expected task demands. Participants also came to appropriately modulate metacognitive monitoring (Experiment 2) and study-time allocation (Experiment 3) across study-test cycles. Item and associative recognition performance, as well as self-report data, revealed shifts in encoding strategies across trials; these results were used to characterize and evaluate the different strategies that participants employed for cued versus free recall and to assess the optimality of participants' metacognitive control of encoding strategies. Taken together, these data illustrate a sophisticated form of metacognitive control, in which learners qualitatively shift encoding strategies to match the demands of anticipated tests.     

UTILIZATION OF METACOGNITIVE JUDGMENTS IN THE ALLOCATION OF STUDY DURING MULTITRIAL LEARNING

Abstract— We contrasted several ways that an individual's judgments of learning (JOLs) can be utilized when allocating additional study ("restudy") during the learning of Swahilt-English translation equivalents The findings demonstrate how metacognitive monitoring can be utilized to benefit multitrial learning Computer-controlled allocation of restudy based on people's JOLs was equivalent to most people's own allocation of restudy (indicating that the computer algorithm can provide a sufficient account of people's allocation of restudy) and was more effective than a computer-controlled allocation based on normative performance (indicating that people's metacognitive monitoring of idiosyncratic knowledge has functional utility in causal chains for learning)     

The effectiveness of updating metacognitive knowledge in the elderly: evidence from metamnemonic judgments of word frequency

Accurate metacognitive knowledge is vital for optimal performance in self-regulated learning. Yet older adults have deficiencies in implementing effective learning strategies and knowledge updating and consequently may not learn as effectively from task experience as younger adults. Here we assess the ability of older adults to update metacognitive knowledge about the effects of word frequency on recognition. Young adults have been shown to correct their misconceptions through experience with the task, but the greater difficulty older adults have with knowledge updating makes it unclear whether task experience will be sufficient for older adults. The performance of older adults in this experiment qualitatively replicates the results of a comparison group of younger subjects, indicating that both groups are able to correct their metacognitive knowledge through task experience. Older adults seem to possess more effective and flexible metacognition than sometimes suggested.     

Study time allocation deficit of older adults: The role of environmental support at encoding?

The present research evaluated both metacognitive and environmental support accounts of age-related changes in the way study time is adapted to task difficulty. The original aim was to examine whether providing environmental support at encoding would allow older adults to adjust their study time to the task difficulty by using effective encoding strategies. The difficulty of the learning task was manipulated by varying the strength of association of cue-target pairs (i.e., weak vs. strong associates). This allowed us to measure metacognitive control in aging and, specifically, the ability to adjust study time according to task difficulty. The level of environmental support at encoding was manipulated to examine whether it could be used by older adults to adjust their study time according to the task difficulty. In contrast to the classical literature on the effect of aging on metacognitive control, we found that older adults were able to adjust their study time to task difficulty when environmental support was provided. Furthermore, providing encoding strategies with information about their effectiveness helped older adults adjust their study time to task difficulty optimally by improving their strategy use and compensating for their associative memory deficit.

Thoughts on Thinking: Engaging Novice Music Students in Metacognition

Achieving expertise in any area requires extensive practice and engagement with the subject one desires to master. As not all practice yields good progress, methods must be found that lead learners to practice effectively. Many experts employ highly tailored practice involving metacognitive processes, but novices rarely engage in frequent and explicit metacognitive strategies during practice. As a result, novice progress may be impeded through repetition of systematic errors and ineffective techniques. Our study provides evidence of the effectiveness of teaching metacognition to novice music students through weekly lessons. Thirty‐five adolescent students of six instructors were randomly assigned to metacognitive focus or existing practice teaching conditions. Students receiving metacognitive teaching achieved higher performance ratings when compared with students receiving control instruction, even though practice time did not vary between groups. These results suggest that having students explicitly verbalize and reflect on their learning process produces more efficient practice and greater end performance.

Prospective Relations Between Dysfunctional Metacognitive Beliefs,Metacognitive Strategies,and Anxiety: Results From a Four-Wave Longitudinal Mediation Model

The metacognitive model of psychological disorders suggests that emotional disorders are related to maladaptive metacognitive strategies corresponding to underlying dysfunctional metacognitive beliefs. There is substantial empirical evidence supporting a role of metacognition in psychopathology, but fewer studies have evaluated the metacognitive model using longitudinal data and taken into consideration its differentiation between components and how they are hypothesized to be related to each other. Thus, more specific model evaluation is important as it relates to identifying mechanisms of disorder with a potential to provide clinical advances. In the present study, 868 participants took part in a 4-wave survey and reported on metacognitive beliefs and strategies and anxiety symptoms. Two longitudinal mediation models (forward and reversed causation) were run to test temporal precedence and bidirectional relations. The results indicated that metacognitive beliefs significantly predicted metacognitive strategies, which further predicted anxiety symptoms and mediated the indirect effect in the relationship between metacognitive beliefs and anxiety over time. The relationship between metacognitive beliefs and anxiety symptoms over time were bidirectional, but this relationship was not accounted for by metacognitive strategies. These findings largely support central predictions set forward by the metacognitive model and indicate that metacognitions play a preceding and maintaining role in anxiety.     

Metacognition and mathematics strategy use

The role of children's metacognitive knowledge in their mathematics strategy use was studied by a longitudinal examination of second graders' effort attributions, metacognition for mathematics, and strategy use while solving mathematics problems. Children's correct use of retrieval, internal and external strategies, and the prevalence of strategy use were assessed in September and the following January. Effort attributions for success and failure were also assessed at both points in time. In January, metacognitive knowledge about mathematics strategies was measured. Second graders possess metacognitive knowledge about mathematics strategies, and this knowledge is correlated most strongly with the tendency to use internal strategies in September and correct internal strategy use in September. Effort attributions measured at both timepoints were significantly related to metacognition. Effort attributions in January also correlated with the tendency to use internal strategies in January. In general, the results are consistent with self-system theories, which posit that metacognition, motivation, and strategy use work together to promote learning.     

Transfer of metacognitive skills and hint seeking in monkeys

Metacognition is knowledge that can be expressed as confidence judgments about what one knows (monitoring) and by strategies for learning what one does not know (control). Although there is a substantial literature on cognitive processes in animals, little is known about their metacognitive abilities. Here we show that rhesus macaques, trained previously to make retrospective confidence judgments about their performance on perceptual tasks, transferred that ability immediately to a new perceptual task and to a working memory task. We also show that monkeys can learn to request "hints" when they are given problems that they would otherwise have to solve by trial and error. This study demonstrates, for the first time, that nonhuman primates share with humans the ability to monitor and transfer their metacognitive ability both within and between different cognitive tasks, and to seek new knowledge on a need-to-know basis.     

Metacognitive awareness of learning strategies in undergraduates

Two studies examined undergraduates’ metacognitive awareness of six empirically-supported learning strategies. Study 1 results overall suggested an inability to predict the learning outcomes of educational scenarios describing the strategies of dual-coding, static-media presentations, low-interest extraneous details, testing, and spacing; there was, however, weak endorsement of the strategy of generating one’s own study materials. In addition, an independent measure of metacognitive self-regulation was correlated with scenario performance. Study 2 demonstrated higher prediction accuracy for students who had received targeted instruction on applied memory topics in their psychology courses, and the best performance for those students directly exposed to the original empirical studies from which the scenarios were derived. In sum, this research suggests that undergraduates are largely unaware of several specific strategies that could benefit memory for course information; further, training in applied learning and memory topics has the potential to improve metacognitive judgments in these domains.

The academic outcomes of working memory and metacognitive strategy training in children: A double‐blind randomized controlled trial

Working memory training has been shown to improve performance on untrained working memory tasks in typically developing children, at least when compared to non‐adaptive training; however, there is little evidence that it improves academic outcomes. The lack of transfer to academic outcomes may be because children are only learning skills and strategies in a very narrow context, which they are unable to apply to other tasks. Metacognitive strategy interventions, which promote metacognitive awareness and teach children general strategies that can be used on a variety of tasks, may be a crucial missing link in this regard. In this double‐blind randomized controlled trial, 95 typically developing children aged 9–14 years were allocated to three cognitive training programmes that were conducted daily after‐school. One group received Cogmed working memory training, another group received concurrent Cogmed and metacognitive strategy training, and the control group received adaptive visual search training, which better controls for expectancy and motivation than non‐adaptive training. Children were assessed on four working memory tasks, reading comprehension, and mathematical reasoning before, immediately after, and 3 months after training. Working memory training improved working memory and mathematical reasoning relative to the control group. The improvements in working memory were maintained 3 months later, and these were significantly greater for the group that received metacognitive strategy training, compared to working memory training alone. Working memory training is a potentially effective educational intervention when provided in addition to school; however, future research will need to investigate ways to maintain academic improvements long term and to optimize metacognitive strategy training to promote far‐transfer.

Adult age differences in the effects of goals on self-regulated sentence processing

The authors examined age differences in adults' allocation of effort when reading text for either high levels of recall accuracy or high levels of efficiency. Participants read a series of sentences, making judgments of learning before recall. Older adults showed less sensitivity than the young to the accuracy goal in both reading time allocation and memory performance. Memory accuracy and differential allocation of effort to unlearned items were age equivalent, so age differences in goal adherence were not attributable to metacognitive factors. However, comparison with data from a control reading task without monitoring showed that learning gains among older adults across trial were reduced relative to those of the young by memory monitoring, suggesting that monitoring may be resource consuming for older learners. Age differences in the responsiveness to (information-acquisition) goals could be accounted for, in part, by independent contributions from working memory and memory self-efficacy. Our data suggest that both processing capacity ("what you have") and beliefs ("knowing you can do it") can contribute to individual differences in engaging resources ("what you do") to effectively learn novel content from text.     

The interplay between value and relatedness as bases for metacognitive monitoring and control: evidence for agenda-based monitoring

Two experiments are reported examining how value and relatedness interact to influence metacognitive monitoring and control processes. Participants studied unrelated and related word pairs, each accompanied by point values denoting how important the items were to remember. These values were presented either before or after each pair in a between-subjects design, and participants made item-by-item judgments of learning (JOLs) predicting the likelihood that each item would be remembered later. Results from Experiment 1 showed that participants used value and relatedness as cues to inform their JOLs. Interestingly, JOLs increased as a function of value even in the after condition in which value had no impact on cued recall. Participants in Experiment 2 were permitted to control study time for each item. Results showed that value and relatedness were simultaneously considered when allocating study time. These results support a cue-weighting process in which JOLs and study time allocation are based on multiple cues, which may or may not be predictive of future memory performance, and complements the agenda-based regulation model of study time (Ariel, Dunlosky, & Bailey, 2009) by providing evidence for agenda-based monitoring.     

Differences in attentional strategies by novice and experienced operating theatre scrub nurses

This study investigated the effect of nursing experience on attention allocation and task performance during surgery. The prevention of cases of retained foreign bodies after surgery typically depends on scrub nurses, who are responsible for performing multiple tasks that impose heavy demands on the nurses' cognitive resources. However, the relationship between the level of experiences and attention allocation strategies has not been extensively studied. Eye movement data were collected from 10 novice and 10 experienced scrub nurses in the operating theater for caesarean section surgeries. Visual scanning data, analyzed by dividing the workstation into four main areas and the surgery into four stages, were compared to the optimum expected value estimated by SEEV (Salience, Effort, Expectancy, and Value) model. Both experienced and novice nurses showed significant correlations to the optimal percentage dwell time values, and significant differences were found in attention allocation optimality between experienced and novice nurses, with experienced nurses adhering significantly more to the optimal in the stages of high workload. Experienced nurses spent less time on the final count and encountered fewer interruptions during the count than novices indicating better performance in task management, whereas novice nurses switched attention between areas of interest more than experienced nurses. The results provide empirical evidence of a relationship between the application of optimal visual attention management strategies and performance, opening up possibilities to the development of visual attention and interruption training for better performance.     

Study efficacy and the region of proximal learning framework

One of the most important reasons to investigate human metacognition is its role in directing how people study. However, limited evidence exists that metacognitively guided study benefits learning. Three experiments are presented that provide evidence for this link. In Experiment 1, participants' learning was enhanced when they were allowed to control what they studied. Experiments 2a-d replicated this finding and showed contributions of self-regulated study to learning. Experiments 3a and 3b showed that, when forced to choose among items they did not know, participants chose the easiest items and benefited from doing so, providing evidence for the link between metacognitive monitoring/control and learning, and supporting the region of proximal learning model of study-time allocation.     

The memorizing effort heuristic in judgments of learning: A developmental perspective

Recent work on adult metacognition indicates that although metacognitive monitoring often guides control operations, sometimes it follows control operations and is based on the feedback from them. Consistent with this view, in self-paced learning, judgments of learning (JOLs) made at the end of each study trial decreased with the amount of time spent studying the item, suggesting that JOLs are based on the memorizing effort heuristic that easily learned items are more likely to be remembered. Study 1 extended investigation to primary school children. Whereas for third to sixth graders (9- to 12-year-olds) JOLs decreased with increasing study time (ST), no such relationship was found for first and second graders (7- and 8-year-olds). For both age groups, however, recall decreased with ST, supporting the validity of the memorizing effort heuristic. Self-reports (Study 2) disclosed the belief that recall should tend to increase with ST. The results bring to the fore the importance of mnemonic cues that shape metacognitive feelings even among primary school children. These cues lie in the very feedback that learners gain on-line from task performance rather than in metacognitive knowledge, and their use may also contribute to increased monitoring accuracy with age.     

Spacing one's study: evidence for a metacognitive control strategy

This article investigated individual control of spacing strategies during study. Three predictions were outlined: The spacing hypothesis suggests that people choose to space their study to improve long-term learning via the spacing effect. The massing hypothesis suggests that people choose to mass their study because of illusions of confidence during study. The metacognitive hypothesis suggests that people control their spacing schedules as a function of their metacognitive judgments of specific to-be-learned items. To test these hypotheses, the authors asked participants to study and make judgments of learning for cue-target pairs. Then, participants were given three choices; they could study the pair again immediately (massed), study the pair again after the entire list had been presented (spaced), or choose not to restudy (done). Results supported a metacognitively controlled spacing strategy-people spaced items that were judged to be relatively easy but massed items that were judged as relatively difficult.     

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。
