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 principled phenomenological interviews: 46 long-term meditators (19 female, 27 male) were instructed to modulate and attenuate their embodied self-experience during magnetoencephalographic monitoring.

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 promising path for advancing such an investigation.

A considerable number of studies have attempted to account for the psychotic aspects of schizophrenia in terms of the influential predictive coding (PC) hypothesis. We argue that the prediction-oriented perspective on schizophrenia-related psychosis may benefit from a mechanistic model that: 1) gives due weight to the extent to which alterations in short- and long-term synaptic plasticity determine the degree and the direction of the functional disruption that occurs in psychosis; and 2) addresses the distinction between the two central syndromes of psychosis in schizophrenia: disorganization and reality-distortion. To accomplish these goals, we propose the Imbalanced Plasticity Hypothesis - IPH, and demonstrate that it: 1) accounts for commonalities and differences between disorganization and reality distortion in terms of excessive (hyper) or insufficient (hypo) neuroplasticity, respectively; 2) provides distinct predictions in the cognitive and electrophysiological domains; and 3) is able to reconcile conflicting PC-oriented accounts of psychosis.

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 and reciprocally support the investigation of one another.

An actor-partner interdependence model (APIM) was applied as part of a structural equation modeling (SEM) analysis aimed at examining the associations between the use of different styles of humor and trauma-related psychopathology. Consistent with our hypotheses, results suggested that benign styles of humor were associated with survivors' lower levels of trauma-related symptoms (actor effects) and also had a buffering effect for the spouse (partner effects).

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 altered through attentional training. These issues are approached through a neurophenomenological exploration of the sense-of-boundaries (SB), the fundamental experience of being an 'I' (self) separated from the 'world' (nonself).

This study examined the relationships between dissociation and posttraumatic stress disorder (PTSD) symptoms among injured survivors of terror attacks and their spouses (N = 210), specifically exploring survivor-spouse dyadic associations. Structural equation modeling and the actor-partner interdependence model were used to test the bidirectional dyadic association of both the survivors' and the spouses' dissociation with PTSD symptoms. The results demonstrated a positive association both between the survivors' trait dissociation and PTSD symptoms and between the spouses' trait dissociation and their PTSD symptoms.

S's unique abilities enable him to describe his inner lived experience with great precision and clarity. S was asked to shift between three different stages: (a) the default state, (b) the dissolving of the SB, and (c) the disappearance of the SB.

Fundamental aspects of trauma--among them dissociation during trauma, which is considered one of the strongest predictors of posttraumatic stress disorder-are not fully understood. This article argues that the application of the phenomenological structure of time and the phenomenological description of the self (minimal self, sense of ownership, sense of agency, sense of self) to dissociation during trauma can improve our understanding of this phenomenon-at its occurrence and during any possible ensuing symptoms. In addition, it is argued that the phenomenological approach, as a method that focuses on the bodily level of experience, in particular the body as it is experienced from within, enables us to penetrate the traumatic experience.
