Our grip on reality is slim, says UCL scientist

Posted by Anonymous on August 5, 2008

The neurological basis for poor witness statements and hallucinations has been found by scientists at UCL (University College London). In over a fifth of cases, people wrongly remembered whether they actually witnessed an event or just imagined it, according to a paper published in NeuroImage this week.

Dr Jon Simons and Dr Paul Burgess led the study at the UCL Institute of Cognitive Neuroscience. Dr Burgess said: “In our tests volunteers either thought they had imagined words which they had actually been shown or said they had seen words which in fact they had just imagined – in over 20 per cent of cases. That is quite a lot of mistakes to be making, and shows how fallible our memory is – or perhaps, how slim our grip on reality is!

“Our work has implications for the validity of witness statements and agrees with other studies that show that our mind sometimes fills in memory gaps for us, and we confuse what we imagined occurred in a situation – which is related to what we expect to happen or what usually happens – with what actually happened.

“Most of us, though, have a critical reality monitoring function so that we are able to distinguish well enough between what is real and what is imagined and our imagination does not have too great an impact on our lives – unless the reality check system breaks down such as after stroke or in cases of schizophrenia.” … – ucla
