Loftus and Palmer (1974)
evaluation
lab experiment, low ecological validity, can increase demand characteristics
sample- only 9 in each group for first experiment, anomalies can skew final result
lab experiment, controlled variables
-
-
-
aim- to investigate the accuracy of EWT in terms of the speed through a video of a car crash. Further to investigate the effect of leading questions on accuracy, 'did you see any broken glass?'
procedure (1st exp)
-
pp divided into 5 groups, with 9 pp in each group
-
different verbs used in each question to insinuate a certain speed, 'smashed', 'hit'
-
results
found that those who predicted a higher speed estimate, were more likely to say that there was broken glass
