We develop a taxonomical framework for classifying challenges to the possibility of consciousness in digital artificial intelligence systems. This framework allows us to identify the level of granularity at which a given challenge is intended (the levels we propose correspond to Marr's levels) and to disambiguate its degree of force: is it a challenge to computational functionalism that leaves...
Identifying what aspects of brain activity are responsible for conscious perception remains one of the most challenging problems in science. While progress has been made through psychophysical studies employing EEG and fMRI, research would greatly benefit from improved methods for stimulating the brain in healthy human subjects. Traditional techniques for neural stimulation through the skull,...
Abstract This study contributes to the theoretical integration of phenomenology and behavioral science by examining how expertise reorganizes conscious experience. From a developmental and communicative perspective, skilled performance represents an epigenetic reconfiguration of awareness—from linguistically mediated control to embodied intuition. We develop an empirical phenomenology of this...
The Free Energy Principle (FEP) and active inference unify perception, action, and learning within a single variational framework, yet they remain silent on why there is phenomenal experience at all. Awareness-First Theory (AFT) proposes an ontological inversion: rather than deriving consciousness from non-experiential dynamics, it takes awareness as ontologically primitive—taken as the base...
According to Odysseus Stone and Dan Zahavi’s view, canonical Phenomenology is specifically concerned with analyzing the mind-world dyad and its theoretical implications for philosophy and science. Despite widespread adoption in therapy and research, they claim that mindfulness is ambiguously described as the practice of bare attention and nonjudgment, either on perceptual objects or subjective...
This paper clarifies the experiential profile of depressive rumination, a form of repetitive and persistent negative thinking that is phenomenologically and aetiologically central in depression. Phenomenological analyses of depression have generally remained too high-level to account for this centrality. Drawing on first-person depression narratives and recent philosophy of psychiatry and...
Serotonergic psychedelics, particularly psilocybin, lysergic acid diethylamide (LSD), and dimethyltryptamine (DMT), are increasingly recognised as powerful tools to advance the understanding of consciousness and its relation to brain activity. Psychedelic research has informed neuroscientific theories that attempt to map neural observations of network connectivity and signal diversity to...
The meta-analysis of the 11-dimensional Altered States of Consciousness (11D-ASC) included three studies that contained duplicated data from other papers: Duerler et al. (2021), Lewis et al. (2017), and Preller et al. (2017). When these studies are removed from the analysis, the results are generally similar to the previously reported findings. Out of 33 comparisons (3 doses x 11 dimensions)...
This paper sheds light on the role of inner speech and self-talk in Borderline Personality Disorder (BPD) by providing a literature review of existing empirical studies on related phenomena. Building on these insights, it explores how processes of linguistic self-relation may affect an individual’s sense of self. More specifically, it examines how processes of inner speech contribute to the...
Cognitive architectures are simplified models of complex neural and behavioral processes, designed to equip artificial agents with flexibility and adaptive behavior. To enhance context-awareness and autonomy in humanoid robots, it is essential to address the role of temporality. The temporal dimension extends far beyond its association with memory, encompassing the continuity of self and...
Abstract The sense of agency is the experience of predicting, initiating, or controlling actions. In this paper, I provide a novel account of the sense of agency that appears in perceptual consciousness. I follow theorists such as Bayne and Prinz in suggesting that the perceptual sense of agency (PSoA) is underpinned by self-monitoring processes. The self-monitoring mechanism compares sensory...
Individuals with schizophrenia have less priors than controls, meaning they rely less upon their prior experiences to interpret the current stimuli. These differences in priors are expected to show as higher alternation rates in bistable perception tasks like the Structure-from-Motion (SfM) paradigm. In this paradigm, continuously moving dots in two dimensions are perceived subjectively as...
Abstract There have been many very promising theories published concerning the generation of consciousness. These theories mostly link the emergence of consciousness to neural activity, but very few attempt to show how that neural activity specifically causes experience to occur. This article explores this problem at the level of individual networks by examining the information changes that...
This micro-phenomenological study examines altered states of consciousness (ASC) during Floatation-REST, a sensory isolation method where individuals lie in a tank filled with Epsom salt-saturated water in complete silence and darkness. Salubrious effects of Floatation-REST have been shown in persons suffering from mental health conditions; these positive outcomes might be related to the...
5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a naturally occurring psychedelic tryptamine. Plants containing 5-MeO-DMT have been used throughout history, and in recent years both synthetic and toad-derived 5-MeO-DMT use is being increasingly reported in naturalistic settings as well as clinical research. However, its subjective effects are not well characterised, and no qualitative research...
Psychedelics are being investigated as therapies for major depression and other mood disorders, but the “tripping” experience remains poorly understood. This paper argues that the epistemic dimensions of psychedelic experience should be considered more carefully, both to characterize better the psychedelic state and to develop and explain therapeutic approaches. I propose a tripartite framework...
The relationship between schizophrenia and psychedelic drug states has long attracted scholarly interest and psychedelics have sometimes been described as psychotomimetic. Sense of self can be understood as the feeling of “mineness” that normally characterizes all experiences. In both schizophrenia and psychedelic experiences, alterations to sense of self are present and correlate with clinical...
Abstract Drawing on an unprecedentedly larger sample (N = 236) than previous studies, we investigated the subjective effects of ibogaine by asking a series of three original, open-ended questions to participants enrolled in an ibogaine-assisted treatment program at a specialized healthcare facility in México. The objective was to characterize the overall phenomenology of the subjective ibogaine...
This work advances the computational account of mind and consciousness, distinguishing them from high-performance computing. We adopt the Turing-theoretic interpretation and argue that the mind is best modelled as a universal Turing machine equipped with formally unbounded memory. Physical systems, including quantum computers, von Neumann architectures, organoids, and the brain as a biological...

BACKGROUND: Politically charged public life supplies powerful symbols that can be recruited into delusional meaning-making. This study examined how political contexts shape the content and experiential structure of delusions in patients with psychotic disorders in Turkey. METHODS: We conducted a retrospective, archive-based qualitative study of inpatient psychiatric records from a tertiary...
