Neural correlates of metacognition: Disentangling the brain circuits underlying prospective and retrospective second-order judgments through noninvasive brain stimulation.

Metacognition encompasses the capability to monitor and control one's cognitive processes, with metamemory and metadecision configuring among the most studied higher order functions. Although imaging experiments evaluated the role of disparate brain regions, neural substrates of metacognitive judgments remain undetermined. The aim of this systematic review is to summarize and discuss the available evidence concerning the neural bases of metacognition which has been collected by assessing the effects of noninvasive brain stimulation (NIBS) on human subjects' metacognitive capacities. Based on such literature analysis, our goal is, at first, to verify whether prospective and retrospective second-order judgments are localized within separate brain circuits and, subsequently, to provide compelling clues useful for identifying new targets for future NIBS studies. The search was conducted following the preferred reporting items for systematic reviews and meta-analyses guidelines among PubMed, PsycINFO, PsycARTICLES, PSYNDEX, MEDLINE, and ERIC databases. Overall, 25 studies met the eligibility criteria, yielding a total of 36 experiments employing transcranial magnetic stimulation and 16 ones making use of transcranial electrical stimulation techniques, including transcranial direct current stimulation and transcranial alternating current stimulation. Importantly, we found that both perspective and retrospective judgments about both memory and perceptual decision-making performances depend on the activation of the anterior and lateral portions of the prefrontal cortex, as well as on the activity of more caudal regions such as the premotor cortex and the precuneus. Combining this evidence with results from previous imaging and lesion studies, we advance ventromedial prefrontal cortex as a promising target for future NIBS studies.

Metacognitive evaluation of postdecisional perceptual representations.

Perceptual confidence is thought to arise from metacognitive processes that evaluate the underlying perceptual decision evidence. We investigated whether metacognitive access to perceptual evidence is constrained by the hierarchical organization of visual cortex, where high-level representations tend to be more readily available for explicit scrutiny. We found that the ability of human observers to evaluate their confidence did depend on whether they performed a high-level or low-level task on the same stimuli, but was also affected by manipulations that occurred long after the perceptual decision. Confidence in low-level perceptual decisions degraded with more time between the decision and the response cue, especially when backward masking was present. Confidence in high-level tasks was immune to backward masking and benefitted from additional time. These results can be explained by a model assuming confidence heavily relies on postdecisional internal representations of visual stimuli that degrade over time, where high-level representations are more persistent.

Bayes Optimal Integration of Social and Endogenous Uncertainty in Numerosity Estimation.

One of the most prominent social influences on human decision making is conformity, which is even more prominent when the perceptual information is ambiguous. The Bayes optimal solution to this problem entails weighting the relative reliability of cognitive information and perceptual signals in constructing the percept from self-sourced/endogenous and social sources, respectively. The current study investigated whether humans integrate the statistics (i.e., mean and variance) of endogenous perceptual and social information in a Bayes optimal way while estimating numerosities. Our results demonstrated adjustment of initial estimations toward group means only when group estimations were more reliable (or "certain"), compared to participants' endogenous metric uncertainty. Our results support Bayes optimal social conformity while also pointing to an implicit form of metacognition.

A systematic review of the relationship between generic and specific metacognitive beliefs and emotion dysregulation: A metacognitive model of emotion dysregulation.

Although a probable association between metacognitive beliefs (also termed 'metacognitions') and emotion dysregulation has been suggested in the literature, the evidence is still sparse and inconclusive. The current study aims to present a comprehensive evaluation of the literature examining the association between metacognitive beliefs and emotion dysregulation. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, a search was conducted on PubMed and Ebsco. A manual search of reference lists was also run. Search terms were 'metacognitions/metacognitive beliefs/positive metacognitive beliefs/negative metacognitive beliefs/cognitive self-consciousness/beliefs about the need to control thoughts/cognitive confidence/negative beliefs about thoughts concerning uncontrollability and danger/AND difficulties emotion regulation/emotion dysregulation'. A total of 19 studies met the inclusion criteria. In both non-clinical and clinical populations, a higher endorsement of dysfunctional metacognitive beliefs was found to be associated with emotion dysregulation and vice versa. A higher endorsement of metacognitive beliefs may be associated, either directly or via maladaptive forms of mental control (e.g., worry, rumination and suppression) to emotion dysregulation. Metacognitive beliefs could be the potential therapeutic target in clinical interventions aimed at reducing emotion regulation difficulties.

The structure of metacognition in middle childhood: Evidence for a unitary metacognition-for-memory factor.

It has been debated whether children's metacognitive monitoring and control processes rely on a general resource or whether metacognitive processes are task specific. Moreover, findings about the extent to which metacognitive processes are related to first-order task performance are mixed. The current study aimed to uncover the relationships among children's monitoring (discrimination between correct and incorrect responses), control (accurate withdrawal of wrong answers), and performance across three memory-based learning tasks: Kanji learning, text comprehension, and secret code learning. All tasks consisted of a study phase, a test phase, monitoring (confidence judgments), and control (maintaining/withdrawing responses). Participants were 325 children (151 second graders [Mage = 8.12 years] and 174 fourth graders [Mage = 10.20 years]). Confirmatory factor analyses showed that a model in which monitoring and control loaded on a joint factor and performance on a separate factor provided the best fit to the data. Fourth graders had better monitoring and control accuracy than second graders. However, the factor structure of metacognition was similar for both age groups, contradictory to the assumption that metacognition generalizes across tasks as children grow older. After accounting for task-specific processes, monitoring and control skills for language-based memory tasks appear to be generalizable in middle childhood. In sum, children's monitoring and control for three separate memory tasks appear to reflect a unitary metacognition-for-memory factor related to, but distinguishable from, performance.

The Relationship Between Mental health, Metacognition, and Emotion Regulation in Older People.

OBJECTIVES: It is unclear if using emotion regulation strategies can help manage the effects of anxiety and depression on metacognitive strategies in older people. This study aimed to verify the effect of emotion regulation in the interaction between mental disorders and metacognition. METHODS: A mediation analysis was performed to assess the role of emotion regulation in the interaction between mental disorders and metacognition in older people. RESULTS: Without mediator control, higher scores indicating mental disorder are associated with reduced metacognition scores. When mediators are added to the model, the mediation effect was significant. An indirect effect of anxiety and depression on metacognition was mediated by cognitive reappraisal to a greater extent than emotional suppression. CONCLUSIONS: Cognitive reappraisal reduced the impact of anxiety and depression on metacognition in older adults. CLINICAL IMPLICATIONS: Including cognitive reappraisal techniques in anxiety and depression intervention plans can be beneficial for improving older people's metacognition functioning.

Acetylcholine and metacognition during sleep.

Acetylcholine is a neurotransmitter and neuromodulator involved in a variety of cognitive functions. Additionally, acetylcholine is involved in the regulation of REM sleep: cholinergic neurons in the brainstem and basal forebrain project to and innervate wide areas of the cerebral cortex, and reciprocally interact with other neuromodulatory systems, to produce the sleep-wake cycle and different sleep stages. Consciousness and cognition vary considerably across and within sleep stages, with metacognitive capacity being strikingly reduced even during aesthetically and emotionally rich dream experiences. A notable exception is the phenomenon of lucid dreaming-a rare state whereby waking levels of metacognitive awareness are restored during sleep-resulting in individuals becoming aware of the fact that they are dreaming. The role of neurotransmitters in these fluctuations of consciousness and cognition during sleep is still poorly understood. While recent studies using acetylcholinesterase inhibitors suggest a potential role of acetylcholine in the occurrence of lucid dreaming, the underlying mechanisms by which this effect is produced remains un-modelled and unknown; with the causal link between cholinergic mechanisms and upstream psychological states being complex and elusive. Several theories and approaches targeting the association between acetylcholine and metacognition during wakefulness and sleep are highlighted in this review, moving through microscopic, mesoscopic and macroscopic levels of analysis to detail this phenomenon at several organisational scales. Several exploratory hypotheses will be developed to guide future research towards fully articulating how metacognition is affected by activity at the acetylcholine receptor.

The Application of the Metacognitive Model of Desire Thinking and Craving in Problematic Social Networking Sites Use.

Cognitive models of addictive behaviours have highlighted the central role of Desire Thinking (DT) - a conscious and voluntary cognitive process orienting to prefigure images and information about a positive target-related experience - in increasing craving and maintaining addictive behaviors. The metacognitive model of DT and craving posits that metacognition plays a central role in understanding dysregulation in DT. The current study aims to test the role of metacognitions about DT, DT, and craving in the relationship between Fear of Missing Out (FoMo), boredom proneness, negative emotional reactivity and Problematic Social Network Sites Use (PSNSU). A sample of 529 participants (Mage= 32.45 ± 13.33; F = 62.9%) completed an online survey. The hypothesised model produced an adequate fit to the data and accounted for 86% of PSNSU variance. FoMO predicted positive metacognitions about DT (PMDT), which predicted DT that, in association with craving, predicted PSNSU. Boredom proneness positively predicted PSNSU directly and indirectly through the serial mediation of PMDT, DT, and craving. A direct path between negative emotional reactivity and PSNSU was found. The current findings provide preliminary evidence for applying the metacognitive model of DT and craving in PSNSU. PMDT and DT may be central cognitive processes in craving and PSNSU for individuals who experience boredom proneness and FoMo.

We know what stops you from thinking forever: A metacognitive perspective.

This commentary addresses omissions in De Neys's model of fast-and-slow thinking from a metacognitive perspective. We review well-established meta-reasoning monitoring (e.g., confidence) and control processes (e.g., rethinking) that explain mental effort regulation. Moreover, we point to individual, developmental, and task design considerations that affect this regulation. These core issues are completely ignored or mentioned in passing in the target article.

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.

Cross-modal metacognition: Visual and tactile confidence share a common scale.

Humans can judge the quality of their perceptual decisions-an ability known as perceptual confidence. Previous work suggested that confidence can be evaluated on an abstract scale that can be sensory modality-independent or even domain-general. However, evidence is still scarce on whether confidence judgments can be directly made across visual and tactile decisions. Here, we investigated in a sample of 56 adults whether visual and tactile confidence share a common scale by measuring visual contrast and vibrotactile discrimination thresholds in a confidence-forced choice paradigm. Confidence judgments were made about the correctness of the perceptual decision between two trials involving either the same or different modalities. To estimate confidence efficiency, we compared discrimination thresholds obtained from all trials to those from trials judged to be relatively more confident. We found evidence for metaperception because higher confidence was associated with better perceptual performance in both modalities. Importantly, participants were able to judge their confidence across modalities without any costs in metaperceptual sensitivity and only minor changes in response times compared to unimodal confidence judgments. In addition, we were able to predict cross-modal confidence well from unimodal judgments. In conclusion, our findings show that perceptual confidence is computed on an abstract scale and that it can assess the quality of our decisions across sensory modalities.

History biases reveal novel dissociations between perceptual and metacognitive decision-making.

Human decision-making and self-reflection often depend on context and internal biases. For instance, decisions are often influenced by preceding choices, regardless of their relevance. It remains unclear how choice history influences different levels of the decision-making hierarchy. We used analyses grounded in information and detection theories to estimate the relative strength of perceptual and metacognitive history biases and to investigate whether they emerge from common/unique mechanisms. Although both perception and metacognition tended to be biased toward previous responses, we observed novel dissociations that challenge normative theories of confidence. Different evidence levels often informed perceptual and metacognitive decisions within observers, and response history distinctly influenced first- (perceptual) and second- (metacognitive) order decision-parameters, with the metacognitive bias likely to be strongest and most prevalent in the general population. We propose that recent choices and subjective confidence represent heuristics, which inform first- and second-order decisions in the absence of more relevant evidence.

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.

Metacognitive interpersonal therapy in borderline personality disorder: Clinical and neuroimaging outcomes from the CLIMAMITHE study-A randomized clinical trial.

Different psychotherapeutic approaches demonstrated their efficacy but the possible neurobiological mechanism underlying the effect of psychotherapy in borderline personality disorder (BPD) patients is poorly investigated. We assessed the effects of metacognitive interpersonal therapy (MIT) on BPD features and other dimensions compared to structured clinical management (SCM). We also assessed changes in amygdala activation by viewing emotional pictures after psychotherapy. One hundred forty-one patients were referred and 78 BPD outpatients were included and randomized to MIT or SCM. Primary outcome was emotional dysregulation assessed with the Difficulties in Emotion Regulation Scale (DERS). We also assessed BPD symptomatology, number of PD criteria, metacognitive abilities, state-psychopathology, depression, impulsiveness, interpersonal functioning, and alexithymia. A subset of 60 patients underwent functional magnetic resonance imaging before and after 1 year of psychotherapy to assess amygdala activation by viewing standardized emotional pictures (secondary outcome). DERS scores decreased in both groups (time effect p < .001). The Cohen's d effect size for change (baseline posttreatment) on DERS was very large (d = 0.84) in MIT, and large (d = 0.76) in SCM. Both groups significantly improved in depressive symptoms, state-psychopathology, alexithymia, and interpersonal functioning. MIT showed larger effect on metacognitive functions than SCM (Time × Group p < .001). Both interventions showed a significant effect on BPD symptomatology although SCM group showed a larger decrease. On the contrary, MIT group showed larger decrease in impulsivity and number of PD criteria. Interestingly, both MIT and SCM modulated amygdala activation in BPD patients. MIT is a valid and effective psychotherapy for BPD with an impact on amygdala activation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Metacognition in working memory: Confidence judgments during an n-back task.

Metacognition in working memory (WM) has received less attention than episodic memory, and few studies have investigated confidence judgements while carrying out a verbal WM task. The present study investigated whether individuals are aware of their own level of performance while carrying out an ongoing verbal WM task, and whether judgments of confidence are sensitive to factors that determine WM performance. A verbal n-back task was adapted to obtain confidence judgments on a trial-by-trial basis. Memory load and lure interference were manipulated. Results showed that metacognition judgments were affected by memory load and levels of interference just as performance accuracy. Even when judgments were sensitive to memory factors, participants were overconfident and generally showed poor metacognitive accuracy at discriminating between erroneous and accurate responses. Results are discussed in terms of possible cues contributing to metacognitive judgements during an ongoing WM task and reasons for WM metacognitive accuracy.

A Cognitive Template for Management of Perioperative Adverse Events.

Perioperative crisis management commonly involves both rapid generic responses and slower abstract reasoning for the successful management of adverse events. A metacognitive approach to this process offers the potential for minimizing errors and thereby improving outcomes. One such metacognitive technique uses templates that guide dynamic decisionmaking. Because stressful circumstances impair memory and cognitive function, templates may be particularly useful during crises both to improve functional recall and to provide mental constructs that compel anesthesia providers to organize their thoughts and direct approaches to problem-solving that rely on critical thinking rather than solely on heuristics. A six-step cognitive template is proposed for formulating a working diagnosis and deciding appropriate therapy during a perioperative adverse event. The template utilizes overlapping differential diagnoses organized using principles of anatomy and/or physiology. It has been effective in nurse anesthesia training to promote a metacognitive approach to decisionmaking during such events, and the template can be widely utilized in nonacademic settings for similar purposes.

Metacognitions about suicidal thoughts.

BACKGROUND: Rumination about suicide has recently been identified as a risk factor for suicidal behavior. According to the metacognitive model of emotional disorders, the activation and maintenance of rumination is dependent on specific metacognitive beliefs. On this background, the current study is concerned with the development of a questionnaire to assess suicide-specific positive and negative metacognitive beliefs. METHODS: Factor structure, reliability and validity of the Scales for Suicide-related Metacognitions (SSM) were investigated in two samples comprised of participants suffering from lifetime suicide ideation. Participants of sample 1 (N = 214; 81.8% female; Mage = 24.9, SDage = 4.0) took part in a single assessment using an online survey. Participants of sample 2 (N = 56; 71.4% female; Mage = 33.2, SDage = 12.2) took part in two online assessments within a two week time-period. To establish convergent validity questionnaire-based assessments of suicidal ideation, general and suicide specific rumination and depression were used. Furthermore, it was analyzed whether suicide-related metacognitions predict suicide-specific rumination cross-sectionally and prospectively. RESULTS: Factor analyses revealed a two-factor structure of the SSM. Results indicated good psychometric properties, and provided evidence for construct validity and stability of the subscales. Positive metacognitions predicted concurrent and prospective suicide-specific rumination beyond the effect of suicide ideation and depression and rumination predicted concurrent and prospective negative metacognitions. CONCLUSION: Taken together the results provide initial evidence that the SSM is a valid and reliable measure of suicide-related metacognitions. Furthermore, findings are in line with a metacognitive conceptualization of suicidal crises and provide first indications of factors that might be relevant for the activation and maintenance of suicide-specific rumination.

General knowledge norms: Updated and expanded for German.

The general knowledge questions introduced by Nelson and Narens (Journal of Verbal Learning and Verbal Behavior, 19(3), 338-368, 1980) have been a valuable research tool in various areas of cognitive research. We translated, updated, and expanded the set of questions for German. We present a total set of 356 general knowledge questions with their recall probability as well as metacognitive measures-confidence and peer judgments-based on a university student sample (N = 512). Furthermore, we present response latencies, pairwise correlations between recall probability and metacognitive judgments as well as the most common commission errors. These general knowledge questions can be used in studies with German speaking participants in a broad range of research fields, such as memory, illusory truth, misinformation, and metacognitive processes.

Motor outcomes congruent with intentions may sharpen metacognitive representations.

We can monitor our intentional movements and form explicit representations about our movements, allowing us to describe how we move our bodies. But it is unclear which information this metacognitive monitoring relies on. For example, when throwing a ball to hit a target, we might use the visual information about how the ball flew to metacognitively assess our performance. Alternatively, we might disregard the ball trajectory - given that it is not directly relevant to our goal - and metacognitively assess our performance based solely on whether we reached the goal of hitting the target. In two experiments we aimed to distinguish between these two alternatives and asked whether the distal outcome of a goal-directed action (hitting or missing a target) informs the metacognitive representations of our own movements. Participants performed a semi-virtual task where they moved their arm to throw a virtual ball at a target. After each throw, participants discriminated which of two ball trajectories displayed on the screen corresponded to the flight path of their throw and then rated their confidence in this decision. The task included two conditions that differed on whether the distal outcome of the two trajectories shown matched (congruent) or differed (incongruent). Participants were significantly more accurate in discriminating between the two trajectories, and responded faster in the incongruent condition and, accordingly, were significantly more confident on these trials. Crucially, we found significant differences in metacognitive performance (measured as meta-d'/d') between the two conditions only on successful trials, where the virtual ball had hit the target. These results indicate that participants successfully incorporated information about the outcome of the movement into both their discrimination and confidence responses. However, information about the outcome selectively sharpened the precision of confidence ratings only when the outcome of their throw matched their intention. We argue that these findings underline the separation between the different levels of information that may contribute to body monitoring, and we provide evidence that intentions might play a central role in metacognitive motor representations.

Response generation, not response execution, influences feelings of rightness in reasoning.

It has been argued that the experience of ease (i.e., the ability to quickly generate an initial response) during processing influences one's likelihood of engaging reflectively when reasoning. This is a key facet of Metacognitive Reasoning Theory (MRT) and numerous studies have found support for this claim by showing that answers that come to mind quickly, are associated with higher feelings of rightness (FORs), and less reflective processing. However, the possibility remains that the critical determinant of FORs may be the speed of executing a response and not generating a response, given the nature of the evidence for this claim. Across two experiments, we manipulated the duration of the response execution to identify whether participants' FOR judgements are at least partially based on factors occurring after the initial mental generation of an answer. We found no evidence that FORs nor reflection are influenced by a manipulation of response execution. Broadly, the present investigation provides evidence that the relation between speed of response and FORs is likely due to the speed with which an answer is generated internally, and not the response execution phase. These findings are consistent with Metacognitive Reasoning Theory and provide further support for the suggestion that answer fluency is the critical variable in determining FORs.
