Medium-term Effects of Ayahuasca Consumption in Healthy Adults
Anecdotal reports suggest that ayahuasca consumption can trigger dramatic positive changes. Scientific evidence corroborating this view has been published, but often suffers from a selection bias. Furthermore, although both acute and long-term effects have been studied, medium-term effects are less well known. This pilot will investigate the effects of one-time participation in a shamanistic ceremony, in ayahuasca-naive participants. Neuropsychological measurements will include tests for executive functioning and basic visual processing. Executive functioning is expected to remain stable at post-test and follow-up, while visual processing might be more affected. Well-being and personality measurements will be obtained via self-report questionnaires. Self-reported changes in well-being and personality are hypothesised to remain evident at follow-up. At the time of writing, results were not yet in.
Maarten R. Struijk is currently studying the Brain & Cognition master at the Universiteit van Amsterdam. His bachelor’s thesis was about the relationship between physical fitness and effort-based decision making using a virtual reality paradigm. Maarten is currently setting up his master’s thesis research project concerning the effects of first time ayahuasca use in healthy adults. He is passionate about the field of entheogens, especially in relationship to long term change.
