Regulation of action selection based on metacognition in humans via a ventral and dorsal medial prefrontal cortical network

Effective modulation from the ventral medial to the dorsal medial portion of the prefrontal cortex in memory confidence-based behavioral control

Metacognition includes the ability to refer to one's own cognitive states, such as confidence, and adaptively control behavior based on this information. This ability is thought to allow us to predictably control our behavior without external feedback, for example, even before we take action. Many studies have suggested that metacognition requires a brain-wide network of multiple brain regions. However, the modulation of effective connectivity within this network during metacognitive tasks remains unclear. This study focused on medial prefrontal regions, which have recently been suggested to be particularly involved in metacognition. We examined whether modulation of effective connectivity specific to metacognitive behavioral control is observed using model-based network analysis and dynamic causal modeling (DCM). The results showed that negative modulation from the ventral medial prefrontal cortex to the dorsal medial prefrontal cortex was observed in situations that required metacognitive behavioral control but not in situations that did not require such metacognitive control. Furthermore, this modulation was particularly pronounced in the group of participants who could better use metacognition for behavioral control. These results imply hierarchical properties of metacognition-related brain networks.

Resting state default mode network is associated with wise advising

Default mode network (DMN) may be associated with wisdom (i.e., mature understanding of life featured by perspectival metacognition) when advising from a self-referential perspective due to the involvement of the DMN in reflecting on personal life experiences. After a resting-state functional MRI scan, 52 adults advised some youths going through life dilemmas, half from a second-person perspective and half from a third. After advising each youth, participants indicated the psychological distance they felt between themselves and the youth. The amplitude of low-frequency fluctuation (ALFF) was measured in the DMN during resting states. Moreover, trained raters rated the participants' advice on wisdom criteria (i.e., metacognitive humility (MH), meta-level flexibility, and perspective-taking). The results showed that participants felt a significantly smaller psychological distance from the youth when advising from the second- than the third-person perspective. Moreover, only when advising from the second-person perspective was MH associated with ALFF in regions within the DMN (i.e., right rostral anterior cingulate cortex (ACC) and left dorsomedial prefrontal cortex). The right rostral ACC showed a significantly greater association with MH from the second- than the third-person perspective. Therefore, resting-state DMN activities may be important for self-involved wisdom performance (e.g., giving advice directly to others).

Tinnitus and Metacognitive Beliefs-Results of a Cross-Sectional Observational Study

Recent research has highlighted the role of metacognitions as a moderator for psychological distress in patients with chronic diseases. The present study investigates the role of metacognitions and worry in the association between tinnitus distress, anxiety, and depression. A cross-sectional study was carried out with a sample of tinnitus-outpatients who completed the Tinnitus-Handicap Inventory, Beck Anxiety Inventory, Beck Depression Inventory, Metacognition Questionnaire-30, Penn-State-Worry-Questionnaire. Associations of metacognitions, worries, tinnitus distress, anxiety and depression were investigated using structural equation models (SEMs). A sample of n = 107 patients was included in the study. In the first SEM, tinnitus distress significantly predicted depression (β = 0.68, p < 0.001) and anxiety (β = 0.47, p < 0.001). In the second model, worries and meta-cognitions were added as moderators. The explained variance substantially increased for depression (46 to 53%) and anxiety (22 to 35%) and the association of tinnitus distress with depression (β = 0.57, p < 0.001) and anxiety was weakened (β = 0.32, p < 0.001). Negative beliefs significantly predicted worries (β = 0.51, p < 0.001) and explained 41% of its variance. A good model fit for the final model was found (comparative fit index (CFI) = 0.98; (Tucker Lewis index) TLI = 0.96; root mean square error of approximation (RMSEA) = 0.067). Anxiety and depression in tinnitus patients might be influenced by worries, which is mainly predicted by negative beliefs about uncontrollability and danger of worries. Thus, psychotherapeutic approaches focused on alterations of metacognitions in patients with tinnitus should be investigated in future studies.3 (List three to ten pertinent keywords specific to the article yet reasonably common within the subject discipline.)

Slow Progress with the Most Widely Used Animal Model: Ten Years of Metacognition Research in Rats, 2009-2019

Until recently, demonstrations of metacognition in primates have been frequent and robust, while in rodents they have been few and equivocal. However, the past few years have seen a change in this trend with the introduction of novel methods to determine whether metacognitive responding is governed by internal or external sources of stimulus control in rats. Such studies suggest that like primates, rats can indeed use internal assessment of memory strengths to guide metacognitive responding. Strong behavioral paradigms suitable for rodents support the development of easily-accessible animal models for the neurobiology of metamemory and translational studies on diseases of memory. They also allow for a more complete comparative study of the evolution of metacognition, as the presence of this ability in rodents would suggest that metacognition evolved ~80 rather than ~25 million years ago.
