Document Summary
General procedure of police interviews: interviewer asks witness to describe what happened then asks brief direct questions ex. What colour was his hair? results in brief responses (not good) wraps up with is there anything else you can remember? . Issues: interrupting the witness study: unravel procedure results: interruptions increase an individuals error rate by a lot inappropriate sequencing of questions interview asking too many direct questions. Misinformation effect memory is reconstructive every time we recall an event the memory becomes destabilized misinformation must occur after (1) exposure to the event and berfore (2) being asked about the event. > changing a single word can change the memory of an event. Harris (1973) study: participants told to give their best guest; didn t watch any stimuli in advance. 13 stories one word can make a difference in how people answer the question. Loftus (1975) participants had to use recollection (vs guessing) > anchoring affects how people answer the question.
