Inverted hallucinations

Dr William Van Gordon will lecture at 6pm on Thursday 11th July, at the University of Derby campus, on “Inverted Hallucinations: a public health barrier to healthy and smart communities”. He was interviewed on the BBC Radio 4 Today programme this morning (07.42h) about his subject.

Dr Van Gordon will argue that inverted hallucinations give rise to states of maladaptive mind wandering, blunt an individual’s perception of what is happening in the present moment, and lead to the spread of “small mindedness”.

The term “negative hallucination” first appeared in “Psychical (or Mental) Treatment” (Freud, 1890), an article relating to hypnosis. Freud wrote that it was possible to suggest to a hypnotised subject that he or she not see a person or thing that would be present to the subject upon awakening; in such cases the object appears to be “thin air”. Freud borrowed this notion from Hippolyte Bernheim, with whom he studied to perfect his hypnotic technique. (Read more of this in the International Dictionary of Psychoanalysis.)

Why not take 2m44s to watch Professor Richard Wiseman’s Colour Changing Card Trick on YouTube?

Not if you’re supposed to be paying attention to something else, though.
