Abstract

The helioscope effect refers to trauma-related memory processing, facilitated by psychedelic substances, in which difficult memories become accessible without compromising emotional safety. The concept is grounded in both qualitative and quantitative research involving substances such as psilocybin, LSD, and MDMA. It identifies three core therapeutic mechanisms: enhanced emotional accessibility, reduced avoidance, and simultaneously increased protection against retraumatization. This effect is supported by specific contextual factors – most notably, therapeutic preparation and integration, clearly defined therapeutic intentions, and a safe, contained setting. The article explores the neurobiological underpinnings of the helioscope effect, its relevance for trauma therapy and its contribution to psychotherapy process research.
