COGNITIVE PSYCHOLOGY - THE EFFECTS OF MISLEADING INFORMATION ON THE ACCURACY OF EWT

• MISINFORMATION ACCEPTANCE - PEOPLE ACCEPT MISLEADING INFORMATION AFTER AN EVENT AND ABSORB INTO THEIR MEMORY FOR THE ACTUAL EVENT

LOFTUS (1975) SHOWED PARTICIPANTS FILM OF EVENTS LEADING UP TO A CAR ACCIDENT. PARTICIPANTS WERE THEN DIVIDED INTO A CONTROL GROUP AND AN EXPERIMENTAL GROUP. THE CONTROL GROUP WAS ASKED QUESTION CONSISTENT WITH WHAT THEY HAD ACTUALLY SEEN, (HOW FAST WAS THE CAR GOING WHEN IT PASSES THE STOP SIGN?) WHEREAS THE EXPERIMENTAL GROUP WERE ASKED QUESTIONS THAT CONTAINED MISLEADING INFORMATION, ( HPW FAST WAS THE CAR GOING WHEN IT PASSES THE BARN TRAVELLING ALONG THE COUNTRY ROAD?). BUT THERE WAS NO BARN IN THE FILM.

FOUND 17% OF THE PARTICIPANTS FROM THE EXPERIMENTAL GROUP REPORTED SEEING A BARN.

CONCLUDED THAT SOME PARTICIPANTS GIVEN THE MISLEADING INFORMATION HAD ABSORBED THIS WITH THEIR ORIGINAL MEMORY, AND REALLY BELIEVED THEY HAD SEEN A BARN.
