Background: In the last decade, empirical studies on the beneficial effects of meditation on prosocial capacities have accumulated, but the underlying mechanisms remain unclear. Buddhist sources state that liberating oneself from a fixed view of the self by gaining access to its transitory and malleable nature leads to increased compassion and othe...

There is a growing hype regarding the efficacy of psychedelics to fundamentally change how we interact with the theme of death. The underlying evidence consists of anecdotal and self-report data collected in naturalistic and clinical settings suggesting that psychedelics inculcate more acceptance and less fear and anxiety of one’s mortality. Howeve...

Background: How the human psyche interacts with the theme of death is fundamental to individual and societal life, profoundly influencing cognition, affect, and behavior. Death-related psychological phenomena, such as death anxiety and acceptance, have been shown in clinical studies to be influenced by psychedelic (LSD and psilocybin) interventions...

There is a renewed interest in taking phenomenology seriously in consciousness research, contemporary psychiatry, and neurocomputation. The neurophenomenology research program, pioneered by Varela (1996), rigorously examines subjective experience using first-person methodologies inspired by phenomenology and contemplative practices. This review exp...

Human experience is imbued by the sense of being an embodied agent. The investigation of such basic self-consciousness has been hampered by the difficulty of comprehensively modulating it in the laboratory while reliably capturing ensuing subjective changes. The present preregistered study fills this gap by combining advanced meditative states with...

The primary objective was to explore the effects of a body scan meditation, a form of mindfulness practice, on reducing negative affect and food cravings in emotional eaters. We also examined if rumination, perceived body boundaries, and spatial frames of reference mediated this effect. Additionally, we investigated whether trait measures of mindfu...

Introduction Despite an emerging understanding regarding the pivotal mechanistic role of subjective experiences that unfold during acute psychedelic states, very little has been done in the direction of better characterizing such experiences and determining their long-term impact. The present paper utilizes two cross-sectional studies for spotlight...

Human experience is imbued by the implicit sense of being an embodied agent, differentiated from but acting on an external world. Because this basic, embodied sense of self is both pervasive and implicit (i.e., pre-reflective), its investigation requires broad means of manipulation, as well as rigorous first-person methodology for mapping ensuing s...

The current study explored the phenomenology of emotional eating, that is, the descriptive knowledge of what one perceives, senses, and knows in one's immediate awareness and experience during emotional eating. Eight individuals with emotional eating were interviewed twice using explicitation interviewing. Data were analyzed using thematic analysis...

Eight individuals with emotional eating were interviewed twice using explicitation interviewing. Thematic analysis resulted in nine themes...

Objectives One of the primary goals of Buddhist-inspired mindfulness practice is to enable practitioners to gain insight into the nature of the self and, as a result, increase their wellbeing. To empirically investigate how mindfulness impacts the self, researchers must effectively explicate the self and hone the methods used to study it. The curre...

Objectives Research exploring how mindfulness is conceptualized and applied in Western psychotherapeutic settings is in its early stages. The current study examines the influence of psychotherapists’ personal practice of mindfulness meditation on their professional work. Methods Psychotherapists who identify as mindfulness teachers were interviewe...

Background Exposure to maternal major depressive disorder (MDD) bears long-term negative consequences for children's well-being; to date, no research has examined how exposure at different stages of development differentially affects brain functioning. Aims Utilising a unique cohort followed from birth to preadolescence, we examined the effects of...

Sensitivity to suffering of others is a core factor in social cohesion and evolutionary success. The emergence of such sensitivity may occur via two neuro-functional mechanisms. One is sharing the pain and distress of others, which relies on affective empathy. The other involves a caring concern for others' wellbeing, termed compassion. Both affect...

A fundamental aspect of the sense of self is its pre-reflective dimension specifying the self as a bounded and embodied knower and agent. Being a constant and tacit feature structuring consciousness, it eludes robust empirical exploration. Recently, deep meditative states involving global dissolution of the sense of self have been suggested as a pr...

Attention Deficit Hyperactive Disorder (ADHD) is a common neurobehavioral disorder with a significant and pervasive impact on patients’ lives. Identifying neurophysiological correlates of ADHD is important for understanding its underlying mechanisms, as well as for improving clinical accuracy beyond cognitive and emotional factors. The present stud...

This paper is a practical guide to neurophenomenology. Varela’s neurophenomenological research program (NRP) aspires to bridge the gap between, and integrate, first-person (1P) and third-person (3P) approaches to understanding the mind. It does so by suggesting a methodological framework allowing these two irreducible phenomenal domains to relate a...

Objective: Gambling disorder is the first behavioral addiction recognized in the DSM-5. This marks the growing realization that both behavioral and substance-related addictions are manifestations of an 'addicted brain', displaying similar altered neurophysiological mechanisms. A decreased electrophysiological visual P300 is considered a hallmark e...

One of the most challenging questions regarding the nature and neural basis of consciousness is the embodied dimension of the phenomenon, that is, feeling located within the body and viewing the world from that spatial perspective. Current theories in neurophysiology highlight the active role of multisensory and sensorimotor integration in supporti...

Self-specific processes (SSPs) specify the self as an embodied subject and agent, implementing a functional self/nonself distinction in perception, cognition, and action. Despite recent interest, it is still undetermined whether SSPs are all-or-nothing or graded phenomena; whether they can be identified in neuroimaging data; and whether they can be...

Meditation practice can lead to what have been referred to as “altered states of consciousness.”One of the phenomenological characteristics of these states is a joint alteration in the sense of time, space, and body. Here, we set out to study the unique experiences of alteration in the sense of time and space by collaborating with a select group of...

Contemporary philosophical and neurocognitive studies of the self have dissociated two distinct types of self-awareness: a “narrative” self-awareness (NS) weaving together episodic memory, future planning and self-evaluation into a coherent self-narrative and identity, and a “minimal” self-awareness (MS) focused on present momentary experience and...

Despite the wide agreement among educators that classroom learning and teaching processes can gain much from student and teacher questions, their potential is not fully utilized. Adopting the view that reporting both teachers’ (of varying age groups) views and actual classroom practices is necessary for obtaining a more complete view of the phenome...

The present research aims shifting ‘scaffolding’ from an inspiring metaphor to a practical tool to be used by kindergarten teachers when conducting scientific activities. It identifies scaffolding strategies that three experienced kindergarten teachers, ones acknowledged as excelling in science teaching, implicitly used when conducting science acti...
