Metacognitive model of mindfulness

Mindfulness training has proven to be an efficacious therapeutic tool for a variety of clinical and nonclinical health problems and a booster of well-being. In this paper we propose a multi-level metacognitive model of mindfulness. We postulate and discuss following hypothesis: (1) mindfulness is related to the highest level of metacognition; (2) mindfulness depends on dynamic cooperation of three main components of the metacognition (metacognitive knowledge, metacognitive experiences and metacognitive skills); (3) a mindful meta-level is always conscious while the other meta-cognitive processes can occur implicitly; (4) intentionally practiced mindfulness decreases dissociations between awareness and meta-awareness; (5) components of mindful meta-level develop and change during continuous practice. The current model is discussed in the light of empirical data and other theoretical approaches to mindfulness concept. We believe that presented model provides some helpful avenues for future research and theoretical investigations into mindfulness and the mechanisms of its actions.     

Metacognition and memory for nonoccurrence

A familiar hypothesis about the recognition of distractor items as "new" is that it depends heavily on a metacognitive strategy in which the memorability or salience of the distractor is evaluated: if the item was deemed salient or memorable and yet no memory trace for it can be found, then it must not have been studied (e.g. Strack & Bless, 1994). In four experiments, no evidence was found to support this metamemory hypothesis. Experiments 1a, 1b, and 2 demonstrated that the judged salience of the stimuli did not predict participants' recognition judgements for distractors. In Experiments 3a and 3b, instructional manipulations designed to affect the ostensible metacognitive process failed to affect the recognition judgements. Finally, Experiment 4 indicated that confidence judgements do not support the predictions of the metamemory hypothesis.     

Acute aerobic exercise improves memory across intensity and fitness levels

ABSTRACT

The present study was designed to examine the impact of exercise intensity and aerobic fitness on free recall, judgments of learning (JOLs), and metacognitive accuracy. In Experiment 1, 30 college students engaged in either (1) no exercise, (2) light exercise (55% of predicted maximal heart rate), or (3) moderate exercise (75% of predicted maximal heart rate) on three different days. In Experiment 2, 29 high-fit students (VO₂ max?≥?70th percentile) and 28 low-fit students (VO₂ max?≤?50th percentile) completed sedentary and light exercise conditions. In both experiments, free recall scores significantly increased in the exercise conditions compared with the sedentary condition, but JOL magnitude and metacognitive accuracy were largely unaffected. These results demonstrate that exercise can improve recall at both light and high intensities, and that the benefit can be obtained by individuals regardless of their fitness level.     

The Longevity Effects of Religious and Nonreligious Participation: A Meta‐Analysis and Meta‐Regression

Scholars have long argued that the reduced mortality risk associated with frequent participation in religious services derives from two sources: social participation and religious belief efficacy. In contrast, the reduced mortality risk associated with participation in nonreligious groups is thought to derive solely from the social participation component. This study tests the religious efficacy hypothesis by comparing the effects of religious participation with nonreligious participation using meta‐analyses of 312 mortality risk estimates from 74 publications (providing data on more than 300,000 persons). We found no significant difference between the mean hazard ratio (HR) for low religious participation (HR, 1.32; 95% CI, 1.24–1.41) and the mean HR for low nonreligious participation (HR, 1.25; 95% CI, 1.17–1.33). These findings suggest that the positive health effects of religious participation may largely be attributed to the social participation component, rather than to the religious component of the act.

Prospective associations between physical fitness and executive function in adolescents: The UP&DOWN study

IntroductionThe objective of the present work is to investigate the prospective associations between physical fitness components (cardiorespiratory fitness, motor fitness, and muscular strength) and two domains of executive function (working memory and inhibitory control) in adolescents.MethodsA total of 422 Spanish adolescents (13.35 ± 1.54 years, at baseline) from the UP&DOWN study with assessments at baseline and at 2-year follow-up were included in the analysis. Physical fitness was assessed using the ALPHA Fitness Test Battery. Working memory was measured by the n-back task and inhibitory control by the go/no-go task. Relationships of physical fitness components with working memory and inhibitory control were examined using linear regression models, adjusted for confounders.ResultsHigher baseline levels of the three physical fitness components (cardiorespiratory fitness, motor fitness, and muscular strength) individually predicted better performance on the working memory (β_ranged, from .159 to .207; all p < .012) and inhibitory control (β_ranged, from 0.168 to 0.263; all p < .004) tasks at the 2-year follow-up. Muscular strength was the only component associated with inhibitory control independent of the other 2 physical fitness components (β = 0.266; p = .005).ConclusionsAll components of adolescents’ physical fitness at baseline were individually associated with better working memory and inhibitory control at 2-year follow-up. Specifically, our results revealed that muscular strength was the component showing the strongest association with executive function, and even the only fitness component associated with inhibitory control independent of the other fitness components. These findings may have important public health and educational implication, since promoting exercise programs that improve physical fitness, and particularly, muscular strength, may positively influence cognitive health.     

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.     

元认知监控的机制:认知灵活性的调节作用

元认知监控作为元认知的核心成分,是内隐程度较高的心理活动。研究采用认知操作法,以MasterMind游戏任务为载体,从执行功能中认知灵活性的角度,探讨了元认知监控的内部机制。结果发现:元认知监测对元认知控制的作用受到认知灵活性的调节作用。对于高认知灵活性的学生,元认知监测水平越高,元认知控制越好;对于低认知灵活性的学生,元认知监测水平的高低不会引起元认知控制水平的显著变化。研究结果表明,高认知灵活性的学生能根据元认知监测进行有效元认知控制,而低认知灵活性的学生其元认知监测水平的提高没有影响元认知控制。结合元认知监控与执行功能进行了讨论。     

Relationships between metacognitive beliefs,social evaluative threat and worry

A worry state is assumed to emerge from the interaction between metacognitive beliefs, and the appraisal of environmental demands (Wells & Matthews, 1994). The aim of this study was to show that metacognitive beliefs moderate the effect of sources of social evaluative threat on worry. Our sample (N = 174) completed a working memory task in two contexts (threatful vs. neutral), while both pre- and post-task measures subjective stress states were recorded. Our results confirmed significant effects of sources of social evaluative threat and metacognitive beliefs on worry. The interaction metacognition * threat context effect on worry was not significant. Our findings support the hypothesis that worry is a form of subjective stress explained by a combination of outcome uncontrollability and social evaluative threat. Social evaluative threat and metacognitive beliefs appeared as two, independent predictors of a worry state. Our results are discussed in reference to the Self Regulative model of stress.
