From Self-Esteem to Selflessness: An Evidence (Gap) Map of Self-Related Processes as Mechanisms of Mindfulness-Based Interventions

Self-related processes (SRPs) have been theorized as key mechanisms of mindfulness-based interventions (MBIs), but the evidence supporting these theories is currently unclear. This evidence map introduces a comprehensive framework for different types of SRPs, and how they are theorized to function as mechanisms of MBIs (target identification). The evidence map then assesses SRP target engagement by mindfulness training and the relationship between target engagement and outcomes (target validation). Discussion of the measurement of SRPs is also included. The most common SRPs measured and engaged by standard MBIs represented valenced evaluations of self-concept, including rumination, self-compassion, self-efficacy, and self-esteem. Rumination showed the strongest evidence as a mechanism for depression, with other physical and mental health outcomes also supported. Self-compassion showed consistent target engagement but was inconsistently related to improved outcomes. Decentering and interoception are emerging potential mechanisms, but their construct validity and different subcomponents are still in development. While some embodied self-specifying processes are being measured in cross-sectional and meditation induction studies, very few have been assessed in MBIs. The SRPs with the strongest mechanistic support represent positive and negative evaluations of self-concept. In sum, few SRPs have been measured in MBIs, and additional research using well-validated measures is needed to clarify their role as mechanisms.

Mechanisms of mindfulness: Evaluating theories and proposing a model

<p>Clinical interest in mindfulness theories and interventions for the treatment of psychological problems such as anxiety and mood disorders has increased dramatically over the last decade. Alongside this interest relatively little attention has been paid to the hypothesised mechanisms of mindfulness that result in a mindfulness state; practice has outstripped the development of a coherent model of the mechanisms. The Decontextualising Model of Mindfulness (DMM) is proposed here to address this gap. The DMM suggests that mindfulness techniques operate to decontextualise mental events from their web of hierarchically organised levels of abstraction and associated meaning, which opens up the cognitive “space” to introduce more adaptive strategies. The DMM is evaluated in terms of its ability to explain existing theories, cognitive-behaviour therapy, and accepted mechanisms of change in psychotherapy. The DMM aims to stimulate deeper understanding of how mindfulness works so that (1) Mindfulness-Based Interventions (MBIs) are more equipped to induce mindfulness states; (2) the origins of psychopathology may be better understood and therefore more effectively treated; and (3) the causes of psychological well-being may be made more clear and therefore more readily enhanced. The research and theoretical literature as well as the current investigation indicate that in particular self-identity and self-compassion are two areas that warrant further investigation.</p>

The Political Consequences of Be(com)ing Mindful. How Mindfulness Might Affect Political Attitudes

Though research provides ample evidence that mindfulness shapes psychological processes and states that are linked to political attitudes and behavior, political science has so far largely ignored mindfulness as a potential explanatory factor shaping political attitudes and actions. This literature review aims to provide a comprehensive overview of the concept of mindfulness and outlines potential linkages between mindfulness and outlines political attitudes. I begin by identifying gaps in the literature on political attitude formation and change as well as its linkage to political behavior. I then introduce mindfulness as a multifaceted concept, discussing its definitional features and unravelling the mechanisms of mindfulness affecting cognitive and emotional abilities. Building on this foundation, I review research on correlates and effects of mindfulness on attitudes and behaviors related to the political domain, such as pro-environmentalism and pro-social behavior. Critically reflecting on extant research on mindfulness, I propose possible research avenues for political science that enhance its dialogue with neuroscience and social psychology.

Investigating mindfulness influences on cognitive function: On the promise and potential of converging research strategies

Research investigating the effects and underlying mechanisms of mindfulness on cognitive functioning has accelerated exponentially over the past two decades. Despite the rapid growth of the literature and its influential role in garnering public interest in mindfulness, inconsistent methods in defining and measuring mindfulness have yielded variable findings, which contribute to the overall dearth of clear generalizable conclusions. The focus of this article is to address the lack of cohesion in the collective methodologies used in this domain, by providing a new perspective grounded in classic cognitive and experimental psychology principles. We leverage the concept of converging operations to demonstrate how seemingly disparate research strategies can be integrated towards a more unified and systematic approach. An organizing taxonomic framework is described to provide useful structure in how mindfulness can be operationalized, measured, and investigated. We illustrate the rationale and core organizing principles of the framework through a selective review of studies on mindfulness and cognitive control. We then demonstrate the utility of the approach by showing how it can be applied to synthesize extant methodologies and guide the development of future research. Specific suggestions and examples pertaining to experimental design and statistical analysis are provided.

Understanding of mechanisms of mindfulness in the perspective of the predictive coding model (in Japanese)

マインドフルネスは，様々な心理的問題に対して有効であることが示されている。しかし，その効果のメカニズムを説明するために，多くの心理学的概念が導入されているが，統一的な理解は得られていない。本論文では，様々な脳機能を説明できる可能性のある統一理論として近年注目されている予測符号化モデルの観点から，マインドフルネスのメカニズムを考察した。概観の結果，マインドフルネスの特徴は，（1）予測通りの感覚を生成しようとする能動的推論よりも，感覚に応じて予測を更新する知覚的推論による予測誤差の最小化が優勢であること，（2）注意によって感覚入力の精度を高めること，（3）過去の経験に重みづけないことによって，事前の予測の精度を下げること，であると考えられた。これらの特徴は、予測誤差を迅速に最小化し，世界を正確に把握することに繋がると考えられる。予測符号化モデルの観点からマインドフルネスを再定義することで、人間の知覚、行動、認知、感情を説明する統一的な視点から、マインドフルネスのメカニズムを理解できる可能性を議論する。
