EXAM 2: Reconstructive Nature of Memory Flashcards
Misinformation effect
Event -> Misleading information -> Modified knowledge
What are the two types of misinformation
Supplemental and Contradictory
Supplemental information
Extra information that is plausible given the broader contextual setting (book/office example)
Contradictory Information
Information that directly contradicts what was originally witnessed
Loftus and Palmer, 1974
Views a series of slides depicting a car accident, asked “how fast were the cars going when they __ each other?”. The lower estimated speed answers would be “contacted” or “hit”, however the higher estimated speed answers would be “smashed”. Did the question affect memory for the accident? 14% of the hit group said they saw broken glass, and 34% of the smashed group said they saw broken glass.
In the car crash example, what type of misinformation is that?
Supplemental! Broken glass is extra yet plausible info, even more plausible for the smashed group
Stop Sign Example - What was it?
Shown a photo of a car crash where a stop sign was visible. They had to answer questions, “see stop sign, asked about stop sign”, “see stop sign, asked about yield sign”.
Results: 75% accurate for consistent; 40% accurate for inconsistent. This example demonstrates contradictory misinformation because you can “erase” previous memory
Eyewitness testimony
Most important factor in influencing juries. Research demonstrates that eyewitness memory is far more malleable than once thought
What are the two types of lineups?
Simultaneous + Sequential
Simultaneous Lineup
See all photos at the same time when making decision
Relative decision: people choose the person who most resembles their memory of the culprit
Sequential
View photo one-at-a-time
Absolute decision: assess each person in isolation
Impact of positive feedback in a lineup
Increases eyewitness confidence, alters memory for the original events (rate original view as being better, rate that they could make out more facial details)
What are the two sevens sins of memory?
Omission and Commission
Omission
Failure to bring something to mind
Commission
Presence of unwanted or inaccurate memories
