I want that one ...

Research output: Contribution to journalLetterpeer-review


Our tendency not to notice when someone presents us with an item we didn't choose, rather then one we did, is clearly another example of the limits of human conscious awareness (18 April, p 26).

It would be interesting to understand why in 25 per cent of the trials undertaken by Lars Hall and Petter Johansson the substitution was detected. Did the subjects who spotted the switch have some anomalous cognitive skills or were they just paying more attention?
