On the role of exploitation and exploration strategies in the maintenance of cognitive biases: Beyond the pursuit of instrumental rewards.

Why can initial biases persist in repeated choice tasks? Previous research has shown that frequent rewards can lure the decision maker into premature exploitation of a supposedly best option, which can result in the persistence of initial biases. Here, we demonstrate that even in the absence of rewards, initial biases can be perpetuated through a positive testing strategy. After eliciting a biased preference for one of two equally rewarding options, participants (N = 203) could sample freely from both options without the lure of any financial rewards. When participants were told to rule out alternatives in this phase, they explored the supposedly worse option and thereby managed to overcome their initial bias. When told to optimize their strategy, however, they exhibited a positive testing strategy resulting in the continued exploitation of the supposedly better option, a bias they maintained in an incentivized choice phase and later judgments. Across all participants, individual tendencies to exploit one option in earlier phases predicted biased behavior in subsequent phases. The findings highlight that not only the pursuit of instrumental rewards can lead to exploitation and the maintenance of initial biases. We discuss potential consequences for interventions.

Strategic regulation of memory in dsyphoria: a quantity-accuracy profile analysis.

The mechanisms underlying a tendency among individuals with depression to report personal episodic memories with low specificity remain to be understood. We assessed a sample of undergraduate students with dysphoria to determine whether depression relates to a broader dysregulation of balancing accuracy and informativeness during memory reports. Specifically, we investigated metamnemonic processes using a quantity-accuracy profile approach. Recall involved three phases with increasing allowance for more general, or coarse-grained, responses: (a) forced-precise responding, requiring high precision; (b) free-choice report with high and low penalty incentives on accuracy; (c) a lexical description phase. Individuals with and without dysphoria were largely indistinguishable across indices of retrieval, monitoring, and control aspects of metamemory. The results indicate intact metacognitive processing in young individuals with dysphoria and provide no support for the view that impaired metacognitive control underlies either memory deficits or bias in memory reports that accompany dysphoria.

Selecting effectively contributes to the mnemonic benefits of self-generated cues.

Self-generated memory cues support recall of target information more robustly than memory cues generated by others. Across two experiments, we tested whether the benefit of self-generated cues in part reflects a meta-mnemonic effect rather than a pure generation effect. In other words, can learners select better memory cues for themselves than others can? Participants generated as many possible memory cues for each to-be-remembered target as they could and then selected the cue they thought would be most effective. Self-selected memory cues elicited better cued recall than cues the generator did not select and cues selected by observers. Critically, this effect cannot be attributed to the process of generating a cue itself because all of the cues were self-generated. Further analysis indicated that differences in cue selection arise because generators and observers valued different cue characteristics; specifically, observers valued the commonality of the cue more than the generators, while generators valued the distinctiveness of a cue more than observers. Together, results suggest that self-generated cues are effective at supporting memory, in part, because learners select cues that are tailored to their specific memory needs.

Improving prospective memory in school-aged children: Effects of future thinking and performance predictions.

Recently, event-based prospective memory (PM) performance of children has been shown to benefit from different encoding strategies such as imagining the execution of a future PM task (i.e., future thinking) and making performance predictions (i.e., metacognitive monitoring). This study aimed to investigate whether and how these two encoding strategies affect PM performance alone and in combination. For this purpose, 127 children aged 8-11 years were assigned to four encoding conditions: (a) standard, (b) performance predictions, (c) future thinking, and (d) future thinking + performance predictions. The ongoing task performance costs (i.e., attentional monitoring), working memory (WM) span, and metacognitive monitoring judgments, such as task difficulty expectations, performance postdictions, confidence judgments, and strategy use, were also evaluated among participants. The results show that combining future thinking instructions with performance predictions considerably improved children's PM performance without incurring additional attentional monitoring costs. Moreover, whereas children generally tended to overestimate their PM performance, more realistic lower-performance predictions were related to higher PM scores for children in the combined condition. Finally, age, WM, and strategy use significantly predicted PM performance independent of the encoding condition. This study is the first to demonstrate that combining future thinking instructions with performance predictions enhances children's PM performance compared with each encoding strategy alone. Moreover, this work is the first to show that by simply imagining the execution of a PM task, children's prediction accuracy can be improved, which is significantly related to the PM performance advantage.

Examining the effect of list composition on monitoring and control processes in metamemory.

According to the widely accepted cue-utilization view, judgments of learning (JOLs) are thought to be comparative in nature, such that they are sensitive to the relative differences between stimuli. Here, we report the results of three experiments that both support and extend this tenet of the cue-utilization view by examining the impact of relative differences on metacognitive control strategies, including study-time allocation and re-study selection. By presenting word pairs of medium-difficulty intermixed with either easy or difficult word pairs we manipulated list composition to assess the impact of the relative difference between items on individuals' JOLs (Experiments 1 and 2a), study-time allocation (Experiment 1), and re-study selection (Experiments 2a and 2b). First, our manipulation of list composition demonstrated that stimuli of equal difficulty are judged to be more or less memorable depending on the context in which they are presented, thereby confirming previous findings that JOLs are sensitive to the relative differences among items. Second, with regard to metacognitive control strategies, our results indicated that list composition may not impact all control strategies in the same fashion. Specifically, the relative differences between items did not appear to influence the amount of study time allocated to a given item, but did affect which items were selected for re-study. These findings have important applied implications, and may assist in the development of more effective guidance on how to best engage in self-regulated learning.

What characteristics make self-generated memory cues effective over time?

From writing to-do lists to creating mnemonic devices in school, people frequently generate cues to help them remember information. Creating memory cues is a vital aspect of metacognition and allows learners to somewhat control their retrieval circumstances. Across three experiments, we tested the extent to which self-generated memory cues fail at long retention intervals because they are based in fleeting mental states. Participants studied target words and generated mnemonic cues for themselves or for others. Cues intended for others showed greater cue-to-target associative strength, were less distinctive, and were less idiosyncratic (more common) than cues intended for oneself. However, the effectiveness of the cues in supporting recall did not differ by intended recipient at medium (∼3 days) or long (∼1 year) retention intervals. In the third experiment, we directly tested the stability of self-generated cues for oneself (compared to cues for others, descriptions of the target, and focused descriptions) by asking participants to generate cues twice for the same targets across a delay of 3 weeks. Cues intended for others were more stable than all other cues, but the stability of the cues did not affect long term retention. Implications for effective cue generation are discussed.

Effects of aging on value-directed modulation of semantic network activity during verbal learning.

While impairments in memory recall are apparent in aging, older adults show a remarkably preserved ability to selectively remember information deemed valuable. Here, we use fMRI to compare brain activation in healthy older and younger adults during encoding of high and low value words to determine whether there are differences in how older adults achieve value-directed memory selectivity. We find that memory selectivity in older adults is associated with value-related changes in activation during word presentation in left hemisphere regions that are involved in semantic processing, similar to young adults. However, highly selective young adults show a relatively greater increase in semantic network activity during encoding of high-value items, whereas highly selective older adults show relatively diminished activity during encoding of low-value items. Additionally, only younger adults showed value-related increases in activity in semantic and reward processing regions during presentation of the value cue preceding each to-be-remembered word. Young adults therefore respond to cue value more proactively than do older adults, yet the magnitude of value-related differences in cue period brain activity did not predict individual differences in memory selectivity. Thus, our data also show that age-related reductions in prestimulus activity do not always lead to inefficient performance.

Progressing the Development of a Collaborative Metareasoning Framework: Prospects and Challenges.

Metareasoning refers to processes that monitor and control ongoing thinking and reasoning. The "metareasoning framework" that was established in the literature in 2017 has been useful in explaining how monitoring processes during reasoning are sensitive to an individual's fluctuating feelings of certainty and uncertainty. The framework was developed to capture metareasoning at an individual level. It does not capture metareasoning during collaborative activities. We argue this is significant, given the many domains in which team-based reasoning is critical, including design, innovation, process control, defence and security. Currently, there is no conceptual framework that addresses the nature of collaborative metareasoning in these kinds of domains. We advance a framework of collaborative metareasoning that develops an understanding of how teams respond to the demands and opportunities of the task at hand, as well as to the demands and opportunities afforded by interlocuters who have different perspectives, knowledge, skills and experiences. We point to the importance of a tripartite distinction between "self-monitoring", "other monitoring" and "joint monitoring". We also highlight a parallel distinction between "self-focused control", "other-focused control" and "joint control". In elaborating upon these distinctions, we discuss the prospects for developing a comprehensive collaborative metareasoning framework with a unique focus on language as a measure of both uncertainty and misalignment.

The Efficacy of a Metacognitive Training Program in Amnestic Mild Cognitive Impairment: A 6-Month Follow-Up Clinical Study.

This study was conducted in response to the increasing prevalence of Alzheimer's disease (AD) dementia and the significant risk faced by individuals with amnestic mild cognitive impairment with multiple-domain deficits (aMCI-md). Given the promising effects of MTPs, the primary aim of this study was to further explore their impact by assessing the maintenance of their benefits. Thus, 45 participants were randomly allocated in two groups: the Experimental group (n = 22), which received the metacognitive training program (MTP), and the Control group (n = 23) that received the cognitive exercises program (CEP). The training programs-the MTP and the CEP-included 10 individual sessions of a one-hour duration and took place once per week. To test the efficacy of the MTP, cognitive and metacognitive outcomes were compared between two groups-Experimental (EG) and Control (CG)-at four distinct time points: before-after-3 months-6 months after intervention. Based on this study's findings, the positive effects of the MTP were evident over a six-month period. Specifically, already three months post-training, the CG began to show a decline in training-related gains. In contrast, the EG's performance consistently improved, highlighting the superior efficacy of the MTP. Gains attributed to the MTP were detected in cognitive measures: cognitive flexibility and immediate visual recall, as well as in metacognitive measures: metacognitive control, improved metacognitive beliefs of attention, and an increased use of cognitive strategies. In conclusion, the results demonstrated the sustained effects of the MTP in cognitive and metacognitive measures over a period of six months, providing novel insight into the application and efficacy of the MTP in individuals with MCI.

A systematic framework of creative metacognition.

Creative cognition does not just involve cognitive processes in direct service of the main task objective (e.g., idea generation), but also metacognitive processes that monitor and regulate cognition adaptively (e.g., evaluation of ideas and task performance, or development and selection of task strategies). Although metacognition is vital for creative performance, relevant work is sparse, which may be partly due to persistent ambiguities in the theoretical conceptualization of creative metacognition. Therefore, this article proposes a systematic framework of creative metacognition (CMC), which builds on recent advancements in metacognition theory and extends them to meet the specifics of creative cognition. The CMC framework consists of two dynamic components-monitoring and control-and a more static component of metacognitive knowledge, each subsuming metacognitive processes applying to the level of task, performance, and responses. We describe the presumed function of these metacognitive components in the creative process, present evidence in support of each, and discuss their association with related constructs, such as creative self-beliefs. We further highlight the dynamic interplay of metacognitive processes across task performance and identify promising avenues for future research.

Dual-Process Theory and Two Types of Metacognitive Monitoring and Control Processes.

Metacognitive monitoring and control processes are important parts of our cognitive system. In this article, they are considered in the light of the dual-process theory and interpreted as occurring at the level of Type 1 and Type 2 information processing. Associative connection is the main factor that allows us to divide these processes into two types. Accordingly, metacognitive monitoring of the first type occurs when feelings of rightness/error automatically appear along with a certain judgment. The second type occurs when a controlled inference is made about whether a judgment is true or false. Metacognitive control of the first type occurs when the decision to reject, revise or accept the received judgment is associated with the feelings of rightness/error and automatically appears when one of these feelings appears. The second type takes place when a person rejects (or they are unclear) the results of the first type of metacognitive control and deliberately decides what to do with the received judgment - reject, revise or accept.

Metacognitive Differences in Amnestic Mild Cognitive Impairment and Healthy Cognition: A Cross-Sectional Study Employing Online Measures.

This study aimed to examine metacognitive abilities in individuals diagnosed with amnestic mild cognitive impairment (aMCI) by using online metacognitive measures during cognitive tasks. A total of 100 participants were enrolled, all aged 50 or older (mean age = 61.98; SD = 6.27), and with a minimum of six years of education (mean = 14.95; SD = 2.94). The sample included 50 individuals with aMCI (34 females) and 50 healthy controls (HC) (33 females). Both groups underwent metacognitive versions of memory tasks (Doors and People) and executive functions tasks (Wisconsin Card Sorting Test). Metacognition was assessed through confidence ratings given after each answer (referred to as metacognitive monitoring) and the accuracy of the participants' decisions to include or exclude answers from their final scores (known as metacognitive control). The results showed that although individuals with aMCI were aware of their cognitive limitations-evidenced by their lower confidence ratings across all tasks-they still exhibited overconfidence relative to their actual performance. Moreover, they included a greater number of incorrect answers in their final scores compared to the healthy control group. These findings suggest that while individuals with aMCI retain some level of awareness, their self-evaluations appear to lack precision. This observation was consistent across both types of cognitive tasks. The results underscore the need for additional research to better understand metacognition in MCI as well as the interplay between metacognitive monitoring and control.

On the proposed role of metacognition in environment learning: recommendations for research.

Metacognition plays a role in environment learning (EL). When navigating, we monitor environment information to judge our likelihood to remember our way, and we engage in control by using tools to prevent getting lost. Yet, the relationship between metacognition and EL is understudied. In this paper, we examine the possibility of leveraging metacognition to support EL. However, traditional metacognitive theories and methodologies were not developed with EL in mind. Here, we use traditional metacognitive theories and approaches as a foundation for a new examination of metacognition in EL. We highlight three critical considerations about EL. Namely: (1) EL is a complex process that unfolds sequentially and is thereby enriched with multiple different types of cues, (2) EL is inherently driven by a series of ecologically relevant motivations and constraints, and (3) monitoring and control interact to support EL. In doing so, we describe how task demands and learning motivations inherent to EL should shape how metacognition is explored. With these considerations, we provide three methodological recommendations for investigating metacognition during EL. Specifically, researchers should: (1) instantiate EL goals to impact learning, metacognition, and retrieval processes, (2) prompt learners to make frequent metacognitive judgments and consider metacognitive accuracy as a primary performance metric, and (3) incorporate insights from both transfer appropriate processing and monitoring hypotheses when designing EL assessments. In summary, to effectively investigate how metacognition impacts EL, both ecological and methodological considerations need to be weighed.

The network structure of dysfunctional metacognition: Analysis of the MCQ-30.

The Metacognitive Control System (MCS) model gives central importance to maladaptive metacognition in psychological vulnerability and disorder. The metacognitions questionnaire 30 (MCQ-30) is widely used to assess such metacognitions and to establish their effects. Previous studies consistently demonstrate that the MCQ-30 consists of five latent factors, with some factors showing wide-ranging positive associations with symptoms and some demonstrating more specific symptom links. Questions remain concerning relationships between MCQ-items (or domains) and the most central of these outside of the latent-factor model. In the present study we set out to explore the internal structure of the MCQ-30 using network analysis and estimated two graphical Gaussian models, one with items- and one with domains, in an unselected sample (N = 1080). The robustness and stability of the networks, as well as the node predictability were assessed. Among our observations was that the items of the MCQ-30 appeared to cluster in meaningful substructures, corresponding to metacognitive theory. Furthermore, "need for control" was the most centrally placed domain, suggesting it plays an important role in the network and that its activation has a strong influence on other nodes. The theoretical and clinical implications of the current findings are discussed in light of the metacognitive model of psychological disorder.

Dividing attention impairs metacognitive control more than monitoring.

Students consistently report multitasking (e.g., checking social media, texting, watching Netflix) when studying on their own (e.g., Junco & Cotton, Computers & Education, 59[2], 505-514, 2012). Multitasking impairs explicit learning (e.g., Carrier, Rosen, Cheever, & Lim, Developmental Review, 35, 64-78, 2015), but the impact of multitasking on metacognitive monitoring and control is less clear. Metacognition may compete with ongoing cognitive processing for mental resources (e.g., Nelson & Narens, The Psychology of Learning and Motivation, 26, 125-141, 1990) and would be impaired by dividing attention; alternatively, metacognition may require little attention (e.g., Boekaerts & Niemivirta, Handbook of Self-Regulation [pp. 417-450], 2000) and would not be impacted by dividing attention. Across three experiments, we assessed the influence of divided attention on metacognition. Participants made item-by-item judgements of learning (JOLs) after studying word pairs under full or divided attention (Experiment 1) and made restudy choices (Experiments 2 & 3). Dividing attention had little impact on the resolution of learners' metacognitive monitoring, but significantly impaired calibration of monitoring, the relationship between monitoring and control, and the efficacy of metacognitive control. The data suggest that monitoring may require few cognitive resources, but controlling one's learning (e.g., planning what to restudy and implementing a plan) may demand significant mental resources.

Metacognitive Beliefs Uniquely Contribute to Interpersonal Problems: A Test Controlling for Adult Attachment, Big-5 Personality Traits, Anxiety, and Depression.

Interpersonal difficulties are common across psychological disorders and are a legitimate target of treatment. Psychotherapeutic models differ in their understanding of interpersonal problems and how these problems are formulated and treated. It has been suggested that they are both the cause and effect of emotional distress symptoms, that they result from early attachment experiences, and that they are related to personality dimensions. However, the metacognitive model of psychopathology predicts that emotion disorder symptoms and interpersonal problems are linked to a common set of factors involving dysfunctional metacognition. In support of this view, metacognitive therapy has substantially reduced interpersonal problems in patients with anxiety and depression even though interpersonal problems are not directly targeted, indicating a role for metacognitive change. Nevertheless, the relationship between interpersonal problems and metacognitive beliefs remains underexplored, and the statistical control of emotion symptoms, personality, and attachment is important in substantiating any metacognition effects. The aim of the present study was therefore to test metacognitive beliefs as statistical predictors of interpersonal problems while controlling for anxiety/depression, adult attachment, and the Big-5 personality dimensions. In a cross-sectional study, 296 participants completed a battery of self-report questionnaires. We found that positive- and negative-metacognitive beliefs, cognitive confidence, and cognitive self-consciousness accounted for significant and unique variance in interpersonal problems together with avoidant attachment and conscientiousness when the overlap between all predictors was controlled. These findings support the notion that metacognitive beliefs are relevant to interpersonal problems with the potential implication that metacognitive therapy could have particularly broad effects on both emotion disorder symptoms and interpersonal problems.

Age-related differences in effectiveness of item restudy choices: the role of value.

We examined the effect of value on effectiveness of restudy choices in younger and older adults by using an honor or dishonor procedure. In the honor condition, participants restudied the half of the items that they selected for restudy. In the dishonor condition, participants restudied the half of the items that they did not select for restudy. The results showed that younger adults restudied more low-value (1-point) items that they had rated as least-well learned, while older adults restudied more high-value (5-point) items. For younger adults, 1-point-value item performance in the honor condition was reliably higher than it was in the dishonor condition. For older adults, 5-point-value items performance in the honor condition was reliably higher than it was in the dishonor condition. These results suggest that older adults can exert effective restudy choices like younger adults when item value is manipulated.

Metacognitive Control of Categorial Neurobehavioral Decision Systems.

The competing neuro-behavioral decision systems (CNDS) model proposes that the degree to which an individual discounts the future is a function of the relative hyperactivity of an impulsive system based on the limbic and paralimbic brain regions and the relative hypoactivity of an executive system based in prefrontal cortex (PFC). The model depicts the relationship between these categorial systems in terms of the antipodal neurophysiological, behavioral, and decision (cognitive) functions that engender normal and addictive responding. However, a case may be made for construing several components of the impulsive and executive systems depicted in the model as categories (elements) of additional systems that are concerned with the metacognitive control of behavior. Hence, this paper proposes a category-based structure for understanding the effects on behavior of CNDS, which includes not only the impulsive and executive systems of the basic model but a superordinate level of reflective or rational decision-making. Following recent developments in the modeling of cognitive control which contrasts Type 1 (rapid, autonomous, parallel) processing with Type 2 (slower, computationally demanding, sequential) processing, the proposed model incorporates an arena in which the potentially conflicting imperatives of impulsive and executive systems are examined and from which a more appropriate behavioral response than impulsive choice emerges. This configuration suggests a forum in which the interaction of picoeconomic interests, which provide a cognitive dimension for CNDS, can be conceptualized. This proposition is examined in light of the resolution of conflict by means of bundling.

Contribution of degraded perception and insufficient encoding to decisions to mass or space study.

How do learners decide whether to mass or space an item during study? Results from Son (2004) indicate that these decisions are influenced by the degree to which an item is judged to be encoded sufficiently during an initial study episode, whereas others (Toppino, Cohen, Davis, & Moors, 2009) have proposed that degraded perceptual processing contributed to participants' decisions to mass or space study. To reconcile these conflicting conclusions, the current experiments used eye tracking technology to evaluate the contribution of degraded perception and insufficient encoding on learners' study decisions. Participants studied synonym pairs from the graduate record exam (GRE) that varied in item difficulty for 1 s (Experiment 1) or 5 s (Experiment 2) each while their eye movements were recorded. Participants then decided whether to mass, space, or drop each pair in future study. For pairs that were never fixated, and hence not perceived, participants overwhelmingly chose to mass their study, presumably so that they could read the target. For pairs that were processed sufficiently to be perceived, preference for massing and spacing pairs increased with item difficulty (i.e., both increased as pairs became less likely to be fully encoded). Taken together, these data demonstrate a contribution of degraded perception and insufficient encoding for learners' decisions to mass (or space) their study.
