It’s a psychologically intriguing study because it used the psychology lab to conduct the study but it also used the psychology lab as a form of misdirection, so participants wouldn’t realise that the effect of having their ‘thoughts read’ and ‘thoughts inserted into their mind’ was in fact a common trick used in stage mentalism.
The interesting bit came where the researchers recorded whether participants reacted differently when they thought their thoughts were being read (they did) and asked about their experience of it happening (when it never actually did).
They reported a range of anomalous effects when they thought numbers were being “inserted” into their minds: A number “popped in” my head, reported one participant. Others described “a voice … dragging me from the number that already exists in my mind”, feeling “some kind of force”, feeling “drawn” to a number, or the sensation of their brain getting “stuck” on one number. All a striking testament to the power of suggestion.
A really wonderfully conceived study that may provide a useful tool for temporarily inducing the feeling of not controlling your own thoughts – something that occurs in a range of psychological difficulties and disorders.
