UNSW Sydney and Macquarie University psychology researchers have written an article warning that psychedelic therapies may switch on visual mental imagery in people with aphantasia and could raise the risk of intrusive thoughts, while calling for more detailed informed consent.
Known as a blind mind’s eye, people with aphantasia recall personal memories with fewer details and vividness. Visual mental imagery is absent. People with aphantasia cannot visualize objects, people, places, or memories, and they also recall personal memories with fewer details and vividness.
Recent reports, including one published case study and one pre-print along with anecdotal accounts, describe individuals with aphantasia gaining a new capacity to visualize after a single dose of ayahuasca or psilocybin, with positive self-reported outcomes during and after the experience, including within a year post-experience.
I didn’t have any expectations concerning that title, but the more I was astonished. The author did a great job. I spent a few minutes reading and checking the facts. Everything is very clear and understandable. I like posts that fill in your knowledge gaps. This one is of the sort.
