Loftus & Palmer Flashcards
What was the overall aim of the study?
To test if the phrasing of a question would alter memory about a car crash

40, 39, 38, 34, 31
What were L&P’s two conclusions about varying estimates?
1- Response bias - Verb indicates preferred speed
2- Memory distortion - The verb actually alters memory

150
What were the details of the car crash film E2?
Entire film was less than a minute, with the crash lasting 4 seconds
