BackgroundPsychedelic retreats are increasingly used to promote wellbeing outside clinical settings, yet the psychological processes associated with sustained improvements in wellbeing remain poorly understood. From a public mental health perspective, identifying mechanisms that support positive mental health beyond symptom reduction is of growing importance.MethodsThis naturalistic...
The research, understanding, and implementation of psychedelic therapies is characterised by a layered complexity that arises from the dynamic interactions between pharmacological and extra-pharmacological factors, and the embeddedness of psychedelics within broader societal, legal, and regulatory systems ill-equipped to accommodate them. This complexity is compounded by an epistemic...
Research has established that life stress may elevate the likelihood of challenging experiences with psychedelics, which may be linked to poorer outcomes from psychedelic use. Studies have highlighted the importance of therapeutic support, but questions remain about the type of effective support and its specific contribution. We examined the contribution of therapeutic-like contexts and support...

Abstract Background & aims This conceptual paper explores the intersection of attachment theory, psychedelic research, and enculturation dynamics. We aim to understand how both attachment patterns and psychedelic use may jointly influence worldview transformations and enculturation processes. Methods We synthesize theoretical perspectives and empirical findings from multiple fields, including...
Abstract In this chapter, the authors synthesize the relational developmental perspective of attachment theory with a neuroscientific model: the RElaxed Beliefs Under pSychedelics (REBUS). This synthesis, the authors argue, can serve as an organizing framework for psychedelic science. Attachment theory posits that people develop internal working models (IWMs) of relational experiences with...
Abstract Background and aims Emerging research indicates that psychedelics may have therapeutic potential by fostering meaningful experiences that act as “inflection points” in people's narratives of personal development. However, psychedelic research has largely failed to address pertinent developmental considerations. We investigated whether attachment-related variables were associated with...
In this conceptual paper, we suggest that attachment theory is a viable framework for understanding key aspects of embodied religious and spiritual cognition, as seen in religious and spiritual metaphors, rituals, anthropomorphisms, and more. We also discuss embodied cognition as part of mystical experiences and other altered states of consciousness that may occur both within and outside of...
In this paper, we set an agenda for a psychedelic science of spirituality and religion, based on a synthesis of attachment theory with the Relaxed Beliefs Under pSychedelics (REBUS) model. Attachment theory proposes that people develop internal working models (IWMs) of interactions with others from their relational experiences with caregivers. Such IWMs then function as high-level priors...
Intranasal oxytocin (OT) has previously been found to increase spirituality, an effect moderated by OT-related genotypes. This pre-registered study sought to conceptually replicate and extend those findings. Using a single dose of intranasal OT vs placebo (PL), we investigated experimental treatment effects, and moderation by OT-related genotypes on spirituality, mystical experiences, and the...

Abstract In this article, the authors argue that mystical experiences are linked to disorganized attachment via a proposed mediator—the propensity to enter altered states of consciousness (absorption). Using a sample of predominantly religious/spiritual participants (N = 62), they report that disorganized attachment, as identified with the Adult Attachment Interview, predicted lifetime...
In this paper, we present a theoretical model and an empirical review linking disorganized attachment with New Age spiritual beliefs and activities via a proposed mediator; the propensity to enter altered states of consciousness (absorption/dissociation). Utilizing a prospective longitudinal design (N = 62), an empirical test of the mediational model is also provided for illustrational...
M. A. Persinger (2002) claimed that transcranial magnetic stimulation with weak, complex magnetic fields evokes mystical experiences. However, in a double-blind experiment, P. Granqvist, M. Fredrikson, P. Unge, A. Hagenfeldt, S. Valind., et al. (2005) found no effects of field exposure on mystical experiences (N = 89), though a minority of participants reported spontaneous mystical experiences....
Transcranial magnetic stimulation (TMS) with weak (micro Tesla) complex waveform fields have been claimed to evoke the sensed presence of a sentient being in up to 80% in the general population. These findings have had a questionable neurophysiological foundation as the fields are approximately six orders of magnitude weaker than ordinary TMS fields. Also, no independent replication has been...
Abstract: Psychedelic-assisted therapy (PAT) is increasingly used for trauma-related disorders, raising ethical questions beyond client safety. We argue that PAT clients have epistemic needs and clinicians have corresponding obligations that call for epistemic humility and discipline, which are essential for regulating foreseeable epistemic risks and for PAT's ethical structure. Drawing on...
