I heard yesterday in a lecture that there was an experiment in which scientists cured people from arachnophobia by memory erasing. It sounds very far-fetched but it was a lecture by a professor so it is hard to imagine he presented "fake news". Did someone hear about such an experiment. This field really caught me as I understood erasing single bad memories (not a memory that comprises many memories. like they can't erase a single person from one's mind) is pretty much obtained. How is it done? Does someone have reading materials in this topic? ThanksA

    $\begingroup$ I have heard of fear erasure through exposure therapy, and there was a case of arachnophobia being cured after removal of a damaged left amygdala, but I have not heard of deliberate memory erasure. If that was possible it would have huge potential with regard to PTSD etc. With that in mind, my answer in psychology.stackexchange.com/q/16781 covers what I have found on that. $\endgroup$ – Chris Rogers Feb 6 at 9:04
  • $\begingroup$ There are several high profile examples of the inverse: a neutral context being associated, artificially, with one in which some noxious stimulus was delivered. I suppose doing this backwards would be very tricky, esp. since the fear induction studies use tricks to achieve their goal. ncbi.nlm.nih.gov/pmc/articles/PMC3843874 science.sciencemag.org/content/341/6144/387 These studies desperately need replication by an outside group. $\endgroup$ – jonnew Feb 7 at 0:11
  • $\begingroup$ I heard this one a while ago about using propranolol to treat arachnophobia in a small number of patients at the University of Amsterdam. The purported mechanism involved rewriting (effectively erasing) the associated memory, but I am not sure if that theory has held up. Layman version and original paper (2015). $\endgroup$ – Arnon Weinberg Feb 7 at 5:07

    $\begingroup$ That is interesting @ArnonWeinberg, and use of propranolol was discussed in the paper I cited in my answer to the question mentioned in my previous comment. $\endgroup$ – Chris Rogers Feb 7 at 6:53
