Neuroimaging studies have provided evidence that extensive meditation practice modifies the functional and structural properties of the human brain, such as large-scale brain region interplay. However, it remains unclear how different meditation styles are involved in the modulation of these large-scale brain networks. Here, using machine learning and fMRI functional connectivity, we investigated how focused attention and open monitoring meditation styles impact large-scale brain networks. Specifically, we trained a classifier to predict the meditation style in two groups of subjects: expert Theravada Buddhist monks and novice meditators. We showed that the classifier was able to discriminate the meditation style only in the expert group. Additionally, by inspecting the trained classifier, we observed that the Anterior Salience and the Default Mode networks were relevant for the classification, in line with their theorized involvement in emotion and self-related regulation in meditation. Interestingly, results also highlighted the role of specific couplings between areas crucial for regulating attention and self-awareness as well as areas related to processing and integrating somatosensory information. Finally, we observed a larger involvement of left inter-hemispheric connections in the classification. In conclusion, our work supports the evidence that extensive meditation practice modulates large-scale brain networks, and that the different meditation styles differentially affect connections that subserve style-specific functions.

Objectives Autobiographical memory (AM) is linked to the construct of self, which is influenced by mindfulness training. Furthermore, both self-reference and AM can be affected by psychopathological conditions, such as depression. This article offers a critical review with a systematic search of the studies using different paradigms to investigate the effects of mindfulness training on AM, as well as the relationships between trait mindfulness and AM. Methods The review includes studies with behavioral, self-report, and neuroimaging methods by considering both non-clinical and clinical investigations in an integrative perspective. Fifty articles were reviewed. The review addressed the following main fields: mindfulness and autobiographical memory specificity; mindfulness and emotional autobiographical recall; and self-inquiry into negative autobiographical narratives and mindfulness. An additional section analyzed 18 studies that addressed the effects of mindfulness training on memory flashbacks. Results In line with the hypotheses, grounded on theories of AM, self, conscious processing, memory reconsolidation, and Buddhist psychology, the review results suggest that the influences of mindfulness training and trait mindfulness on AM can be related to enhanced cognitive, emotional, and self-referential flexibility. This influence is also associated with improved meta-awareness, acceptance, and the flexibility to shift from a first- to a third-person self-perspective in AM recall. In particular, the review highlights increased self-referential flexibility related to mindfulness, which during AM recall would enable a more balanced retrieval of episodic, semantic, and emotional contents, as well as increased AM specificity and reduced emotional reactivity. A mindfulness-related reconsolidation of the links between AM traces and the self might play a crucial role. The mindfulness-related changes of the experiences during AM recall may be translated into long-term reconsolidation-related changes in the AM traces, with a potential interactive effect on the self, thus becoming more flexible. The review also highlights brain mechanisms underlying these influences, given by changes in activity and functional connectivity of core regions in the default mode network (medial prefrontal cortex and posterior cingulate cortex), salience network (anterior cingulate cortex and anterior insula), and central executive network (dorsolateral prefrontal cortex). Finally, we suggest new research developments from the review and the related theoretical perspective. Conclusion The review results, together with the proposed theoretical accounts, bridge a set of investigations on several autobiographical memory phenomena and mindfulness, and might usefully lead to further studies, also with relevant clinical and cognitive neuroscience implications.

Clinical and neuroscientific evidence indicates that transdiagnostic processes contribute to the generation and maintenance of psychopathological symptoms and disorders. Rigidity (inflexibility) appears a core feature of most transdiagnostic pathological processes. Decreasing rigidity may prove important to restore and maintain mental health. One of the primary domains in which rigidity and flexibility plays a role concerns the self. We adopt the pattern theory of self (PTS) for a working definition of self. This incorporates the pluralist view on self as constituted by multiple aspects or processes, understood to constitute a self-pattern, i.e. processes organized in non-linear dynamical relations across a number of time scales. The use of mindfulness meditation in the format of Mindfulness Based Interventions (MBIs) has been developed over four decades in Clinical Psychology. MBIs are promising as evidence-based treatments, shown to be equivalent to gold-standard treatments and superior to specific active controls in several randomized controlled trials. Notably, MBIs have been shown to target transdiagnostic symptoms. Given the hypothesized central role of rigid, habitual self-patterns in psychopathology, PTS offers a useful frame to understand how mindfulness may be beneficial in decreasing inflexibility. We discuss the evidence that mindfulness can alter the psychological and behavioral expression of individual aspects of the self-pattern, as well as favour change in the self-pattern as a whole gestalt. We discuss neuroscientific research on how the phenomenology of the self (pattern) is reflected in associated cortical networks and meditation-related alterations in cortical networks. Creating a synergy between these two aspects can increase understanding of psychopathological processes and improve diagnostic and therapeutic options.

In this paper, we address core insights from Buddhist psychology about mind-body phenomena and the self, and we relate such insights to the notion of the self-pattern developed in the pattern theory of self. We emphasize the dynamic, temporal and enactive characteristics of the self-pattern, consistent with the core Buddhist notion of non-self. Although there is no one-to-one mapping of Buddhist psychological concepts onto the pattern theory of self, there are important similarities among such concepts and the various processes and dynamical relations that constitute a pragmatic self-pattern that can explain both experiences of self and non-self. Buddhist psychology and the notion of the self-pattern offer mutual insight into the processes, the dynamics, and the implications for questions about well-being and a flexibility that avoids anxiety and reduces attachment, craving, and suffering.

In this chapter, the authors address the development of executive functions and their enhancement by mindfulness-based training, with the implicated neurocognitive mechanisms. Specifically, the development of executive functions, related brain networks, and methods for training them are concisely discussed. Additionally, in more extended sections, the authors review empirical findings on mindfulness meditation training and its effects on cognition, the mechanisms implicated in mindfulness training, mindfulness-based interventions for children and adolescents, and mindfulness training in developmental disorders.

Great scientific effort has been devoted to understanding what drives pro-environmental behaviour, yet the question of the environmental attitude–behaviour gap remains unanswered. Studies have indicated that self-regulation and executive functions may reduce such a gap by increasing individuals’ ability to maintain attention on present actions and to resist goal-conflicting temptations. Given the inherent association of self-regulation and executive functions with dispositional mindfulness, we carried out a cross-sectional study to test the hypothesis of the role of dispositional mindfulness in explaining the phenomenon. Our results showed that higher levels of dispositional mindfulness, measured via the Five Facets Mindfulness Questionnaire (FFMQ), are related to a higher tendency to perform pro-environmental behaviour, and that the observing facet of the construct would predict higher pro-environmental behaviour scores. Interestingly, we also found the acting with awareness and nonjudging factors to be moderators of the relationship between pro-environmental attitudes and behaviours, suggesting that enhanced awareness of the present moment may favour higher congruence between attitudes and behaviours, and that higher acceptance may favour more adaptive coping strategies to the climate challenge. Our findings provide a novel contribution to the understanding of the relationship between mindfulness and pro-environmental behaviour and support the perspective that self-regulation skills would contribute to reducing the environmental attitude–behaviour gap.

The visual appearance of an object is a function of stimulus properties as well as perceptual biases imposed by the observer. The context-specific trade-off between both can be measured accurately in a perceptual judgment task, involving grouping by proximity in ambiguous dot lattices. Such grouping depends lawfully on a stimulus parameter of the dot lattices known as their aspect ratio (AR), whose effect is modulated by a perceptual bias representing the preference for a cardinal orientation. In two experiments, we investigated how preceding context can lead to bias modulation, either in a top-down fashion via visual working memory (VWM) or bottom-up via sensory priming. In Experiment 1, we embedded the perceptual judgment task in a change detection paradigm and studied how the factors of VWM load (complexity of the memory array) and content (congruency in orientation to the ensuing dot lattice) affect the prominence of perceptual bias. A robust vertical orientation bias was observed, which was increased by VWM load and modulated by congruent VWM content. In Experiment 2, dot lattices were preceded by oriented primes. Here, primes regardless of orientation elicited a vertical orientation bias in dot lattices compared to a neutral baseline. Taken together, the two experiments demonstrate that top-down context (VWM load and content) effectively controls orientation bias modulation, while bottom-up context (i.e., priming) merely acts as an undifferentiated trigger to perceptual bias. These findings characterize the temporal context sensitivity of Gestalt perception, shed light on the processes responsible for different perceptual outcomes of ambiguous stimuli, and identify some of the mechanisms controlling perceptual bias.

In three experiments we investigated the effects of selective attention in iconic memory and fragile-visual short-term memory (VSTM), which have been related to phenomenal consciousness. We used a novel retro-cue paradigm with different delays (early vs late) and object priorities (high vs equal vs low), to investigate (a) attentional costs and benefits and the role of (b) bottom-up factors and (c) fragile-VSTM in feature-based attentional selection. Experiment 1 showed that attentional costs modulate visual maintenance at longer delays, while Experiment 2 showed that by reducing the time exposure of the memory array from 250 ms to 100 ms, as a bottom-up factor, participants were not able to select the objects based on their priorities. Finally, Experiment 3 showed that a pattern mask presented before the transfer in visual working memory, attenuates the overall performance while preserving the priority effect. The implications for phenomenal consciousness before conscious access are discussed.
