Psychedelic substances and meditation can elicit personally meaningful experiences that support well-being, yet their relative and combined contributions remain unclear.

The associations between different components of PF, psychological inflexibility (PI), and well-being with psychedelic use are not well understood. We conducted a cross-sectional internet survey of participants (N = 629) with experience of classical psychedelics....

To date, little is known about how attention affects the event-related potential (ERP) correlates of auditory awareness and there is contradictory evidence on whether one of them, the late positivity (LP), is affected by...

A retrospective internet survey was used in a sample of Finnish chronic pain patients (40...
