Investigating the phenomenological matrix of mindfulness-related practices from a neurocognitive perspective.

“…has been operationalized as a stable mental trait that can be measured by a variety of dispositional scales (e.g., the Five Facet Mindfulness Questionnaire, Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006; Baer et al., 2008; or the Mindfulness Attention Awareness Scale (MAAS), Brown & Ryan, 2003).”

“The CEN is responsible for selection, planning, and decision making in the context of goal-oriented behavior, as well as for maintaining and manipulating information in working-memory (Miller & Cohen, 2001).”

“This construct parallels endogenous orienting of attention in psychology, which is manipulated by displaying a cue or other instruction indicating, for example, where in space a target is likely to occur (Posner & Petersen, 1990).”

“The CEN refers here to the bilateral dorsolateral prefrontal cortex (DLPFC), ventrolateral PFC, dorsomedial PFC, and lateral parietal cortices (Seeley et al., 2007) including also rostrolateral PFC (BA10) (Fleming, Weil, Nagy, Dolan, & Rees, 2010).”

“In contemporary clinical practice, practitioners are often taught that, as thoughts and feelings arise during mindfulness meditation, one should maintain an accepting or friendly attitude toward them (Bishop et al., 2004; Shapiro, Carlson, Astin, & Freedman, 2006).”

“Extending this view, Craig (2009, 2010) and Damasio (Damasio, 1996) proposed a model where the insula, in interactions with the thalamus and brainstem (Damasio & Carvalho, 2013), instantiates, from moment-to-moment, high-order neural representation of all subjectively perceived feelings central for…”

“This form of emotion regulation is modulated by other prefrontal networks that are part of the CEN, or salience network (SN) (Ochsner & Gross, 2005).”

“In the first report of the clinical use of mindfulness training to mitigate the effects of such pain, Kabat-Zinn (1982) stressed the fundamental utility of patients learning to observe thoughts as simply events in the mind with no a priori truth value.”

“…also typically activated during tasks that ask participants to engage in internal mentation such as mentalizing, projecting oneself in the future, self-referential thought or decision making (Amodio & Frith, 2006; Andrews-Hanna, Reidler, Sepulcre, Poulin, & Buckner, 2010; Buckner & Carroll, 2007).”

“Similar neuroscientific models of maladaptive appraisal processes have been proposed in anxiety (Etkin & Wager, 2007) and risk-taking behavior in adolescence (Ernst & Fudge, 2009).”

“This ‘default network’ was initially identified during passive, uncontrolled tasks (Gusnard et al., 2001) and is consistently observed at rest using intrinsic functional connectivity MRI measures.”

“As such, MBCT has repeatedly been shown to effectively prevent depression relapse (Segal et al., 2010; Teasdale et al., 2000), as extensively reviewed in Dimidjian and Segal in this volume (Dimidjian & Segal, 2015).”

“The difficulty in specifying mindfulness as a cognitive process stems also from the drive to arrive at a single definition to cover all styles of mindfulness, and in some cases, Buddhist sources have been used to support this type of monolithic definition (e.g., Hölzel et al., 2011).”

“A growing literature reports improvements in attention and working memory with mindfulness training (for a recent review, see, Tang et al., 2015).”

“The function of the default mode has been related to participants’ spontaneous thoughts or mind-wandering (Fox et al., 2015; Mason et al., 2007).”

“In the Attention Network Test (ANT, Fan, McCandliss, Sommer, Raz, & Posner, 2002), for example, the orienting subsystem of attention is characterized by faster target detection reaction times for those targets appearing at locations at which attention was directed prior to the target onset versus targets appearing at…”

“As will be explained further below, it is also a key component of “decentering” (Williams, 2010), “cognitive defusion” (Hayes, 2004), or “metacognitive insight” whereby “thoughts are perceived to be transient, insubstantial mental events rather than accurate representations of reality” (Chambers et al.”

“In its more technical uses, sm ṛ ti or “mindfulness” points to a fundamental capacity to retain an object in cognition, somewhat akin to working memory (Jha, Stanley, & Baime, 2010; Dreyfus, 2011).”

“By phenomenological space, we mean the characterization of categorical features of the field of experience, as it is lived and verbally articulated in the first-person (e.g., Husserl, 2008).”

“In this context, Dereification, or “decentering” (Barnard & Teasdale, 1991; Segal et al., 2012; Teasdale et al., 1995) refers to the ability to observe repetitive negative thinking as a temporary and impersonal process in the mind.”

“With this in mind, we note that revising one’s initial perception of a picture of an injured person as being just a picture taken from a movie (reappraisal) typically down-regulates the activity of subcortical affective regions like the amygdala (Urry et al., 2006).”

“In support of this claim, one study observed an inverted u-shaped curve in CEN activity in expert and novice meditators during FA in which those learning a skill initially had increased activation, yet eventually showed less activation (Brefczynski-Lewis et al., 2007).”

“…the thalamus and brainstem (Damasio & Carvalho, 2013), instantiates, from moment-to-moment, high-order neural representation of all subjectively perceived feelings central for subjective awareness or “conscious presence” (see also Seth, Suzuki, & Critchley, 2011 for a recent mechanistic model).”

“The other style of practice plotted in the figure is Open Monitoring (for an overview see Lutz et al., 2008; Gunaratana, 2002; Namgyal et al., 2004; Goldstein & Kornfield, 2001; Suzuki & Chadwick, 2011).”

“To determine if endogenous orienting is indeed akin to the proposed Object Orientation dimension, we delineate four prominent functional markers of orienting (Mangun, 1995) and review evidence suggesting that MT may improve the efficiency of these identified markers.”

“This tendency to treat Meta-awareness and Dereification as identical also appears in the psychological literature, where accounts of “cognitive defusion” (Hayes, 2004) and “decentering” (e.g., Fresco et al., 2007) do not clearly distinguish these capacities.”

“Jon Kabat-Zinn has noted (Williams & Kabat-Zinn, 2011) that mindfulness can be used as an “umbrella term” for a collection of practices and personal values that enable one to live mindfully.”

“…EEG report that orienting of attention increases phase locking of theta activity (e.g., Sauseng, Hoppe, Klimesch, Gerloff, & Hummel, 2007), and recent studies of MT in long-term retreatants reported greater phase locking to T2 (the second target) in an attentional blink task (Slagter et al., 2007).”

“…these results, in a randomized active control (health education) longitudinal study of compassion-based meditation, Pace et al. (Pace et al., 2010; Pace et al., 2009) found decreased IL-6 and cortisol activations after the TSST in the meditation training group, but only for those who practiced…”

“As noted above, this capacity to detect the “background” or lived subjective context of one’s object-focused experience contrasts with an “inward turn” of attention, often characterized as “introspection,” or retrospective second-order judgment (Fleming & Dolan, 2012; Overgaard & Sandberg, 2012).”

“Next, we briefly describe three neural networks that are often reported in research on mindfulness or in studies that are directly relevant to the dimensions described in our model (Fox, Spreng, Ellamil, Andrews-Hanna, & Christoff, 2015; Tang et al., 2015).”

“In line with improvements in perceptual clarity, MacLean et al. (2010) reported improvements in visual perceptual thresholds in the context of a sustained attention continuous performance vigilance task after three months of intensive FA retreat experience compared to a matched control group.”

“This broader model accounts for salient and alerting affective states, such as fear, which activate the sympathetic automatic nervous system, but could also instantiate parasympathetic-related affective states such as calm, positive feeling (Craig, 2010).”

“In particular, mindfulness practices are now incorporated in a variety of axiological frameworks ranging from traditional religious contexts to educational settings (Flook et al., 2010), military training (Jha et al., 2010) and other contemporary societal contexts such as law (Orenstein, 2011).”

“A similar dimensional approach has been advocated for characterizing mental disorders (Hyman, 2007).”

“Grossman, in his 2008 commentary, has addressed some of these issues (Grossman, 2008; see also Grossman & Van Dam, 2011).”

“…constructs have been studied, for instance in research on trial-to-trial variability in behavioral or neurophysiological measures of vigilance (Lutz et al., 2009; Zanesco, King, Maclean, & Saron, 2013), or in the recovery function in studies of response to aversive stimulation (Schuyler et…”

“It has been defined as the mental state that arises when attention is directed toward explicitly noting the current contents of consciousness (Schooler, 2002; Smallwood & Schooler, 2015).”

“…these phenomenological dimensions and activity in specific brain regions is plausible because studies concerning emotion and cognition have shown that brain regions’ functions are inherently multidimensional, and that structurally different regions can perform the same function (Pessoa, 2014).”

“As such, MBCT has repeatedly been shown to effectively prevent depression relapse (Segal et al., 2010; Teasdale et al., 2000), as extensively reviewed in Dimidjian and Segal in this volume (Dimidjian & Segal, 2015).”

“…studies of attention examining synchronous activity in EEG report that orienting of attention increases phase locking of theta activity (e.g., Sauseng, Hoppe, Klimesch, Gerloff, & Hummel, 2007), and recent studies of MT in long-term retreatants reported greater phase locking to T2 (the…”

“…the aI/dACC acts as a hub whose activity is correlated with changes in subjective feeling states and that flexibly connects not only with fixed anatomical pathways (e.g., amygdala, rTPJ), but also dynamically integrates a broad variety of neural systems (e.g., Jabbi, Bastiaansen, & Keysers, 2008).”

“In a recent study by Moore et al. (2012), participants were given a Stroop task which required them to report the color of the ink regardless of the color word containing the ink.”

“For instance, manipulating task demand to increase difficulty is typically associated with increase BOLD activity in CEN and subcortical reward circuitry (Schmidt et al., 2012).”

“Some researchers have used these scales to characterize clinical groups (e.g., Leigh, Bowen, & Marlatt, 2005) or to identify, in untrained subjects, the neural correlates of dispositional mindfulness (e.g., Creswell, Way, Eisenberger, & Lieberman, 2007).”

“While this proposal is still largely speculative in the context of meditation research, it is now a plausible prediction in light of research on spatially independent patterns of intrinsic brain networks (Calhoun & Adalı, 2012; Jack et al., 2012) and by an alteration of these patterns in clinical populations such as d…”

“And, as mentioned previously, other mechanistic models of mindfulness training describe additional underlying processes that may be equally important in fostering mindfulness and influencing its associated outcomes (e.g., Lutz et al., 2015).”

“The word “mindfulness” corresponds to the translation of the original terms smrti (from Sanskrit) or sati (Pali), which captures the capacity to retain an object in the mind, but in a broad sense also implies being aware of and attentive to the present moment (Lutz et al., 2015).”

“Accordingly, a neurobehavioral perspective has been integral to research on MM (Davidson 2003, Lutz et al. 2007, 2015).”

“In particular, dereification—the recognition that one’s thoughts and experiences are not true reflections of reality (36)—may be a key insight that shifts one’s perspective toward social cognitions and transforms social functioning.”

“In this form of meditation, practitioners cultivate sustained awareness to experience without attempting to control the focus of attention, but rather maintaining openness to any feelings that arise in awareness (Lutz et al., 2015).”

“First, given the significant and growing evidence for the highly active attentional engagement and associated robust modulations of frontal brain circuitry supporting the act of meditative practice (Tang and Posner, 2009; Brewer et al., 2011; Lutz et al., 2015; Tang et al., 2015), it is quite possible that the meditat…”

“In order to capture the phenomenology of deliberate, sustained meta-awareness, as found in meditation practices (Lutz et al. 2015), we define a third layer of hidden states, which represents latent metaawareness states of the agent.”

“Buddhist accounts and empirical studies suggest that various styles of mindfulness training enhance not only smr.ti (‘mindfulness’) as a capacity that prevents distraction, but also samprajanya (‘meta-awareness’) as a capacity to detect distraction when it occurs [11,12].”

“In the scientific literature, mindfulness can refer to a mental state, trait, or faculty amenable to training [44-47].”

“It is the combination of these elements borne by meditative practice that supports the scientific exploration of subtle aspects of consciousness as exhibited in our own research and that of others (Berkovich-Ohana et al., 2013a; Dor-Ziderman et al., 2013, 2016; Zanesco et al., 2013; Jo et al., 2014; Ataria et al., 201…”

“Others have put forth a phenomenological and neurocognitive framework to understand mindfulness meditation that includes interacting dimensions of mind (object orientation, decentering, and meta-awareness) as well as mental qualities (aperture, clarity, stability, and effort) (Lutz et al. 2015).”

“From this perspective, Insight retreats can be conceived of as comprehensive well-being interventions that pair periods of formal meditation practice (e.g., sitting or walking) with a contemplative way of life or ‘‘stance toward experience” (Lutz et al., 2015).”

“Consideration of construct heterogeneity is relatively new to contemplative science (Lutz et al., 2015), and past research often involved studies in which the different facets of mindfulness are subsumed under its namesake.”

“More recently, this system has been refined from a set of bins (FA, OM, LK) to a series of dimensions, along which any practice can vary (Dahl et al., 2015; Lutz et al., 2015).”

“1 3 Recently, new collections and classification systems encompassing a greater variety of meditation techniques have been proposed (Dahl et al., 2015; Lutz et al., 2015).”

“…degree of consciousness, awareness, or phenomenal experience that may or may not go with particular metacontrol states (issues emphasized by meta-awareness approaches; e.g., Chin and Schooler 2010; Lutz et al. 2015) but only considers the functional and neural characteristics of metacontrol states.”

“So, meditation’s orientation toward a present-moment awareness seems to diminish the magnitude of self-referential thinking, hence decreasing the perceived self-other duality (Farb et al. 2007; Lutz et al. 2015; Hasenkamp 2018; Millière et al. 2018; Bauer et al. 2019).”
