Q

What are flashbulb memories?

A

Memories that are incredibly vivid and clear-like a snapshot of a moment in time. Tend to be for very distinctive moments in our lives, have a strong emotional component-positive or negative.

Q

What is the repeated recall paradigm?

A

Used to test accuracy of flashbulb memories-shortly after a major event, make people write down what they were doing when they heard about it
Then, ask them to do the same thing some time later.

Q

What were the results of the repeated recall paradigm on flashbulb memories?

A

The memories became less accurate (ex: 20% of people reported watching 9/11 happen on TV, however, when asked years later, that percentage doubles)

Q

What was Talarico and Rubin’s test on flashbulb memories?

A

Q

What were the results of Talarico and Rubin’s test?

A

Details about the event goes down at the same rate for both flashbulb and personal memories
BUT… confidence in their belief of how accurate they are at remembering stays constant for flashbulb and goes down for personal

Q

What was the conclusion from Talarico and Rubin’s test?

Q

What was Davidson et als test on flashbulb memories?

A

Started the same as Talarico and Rubins, but instead, scored them from a 0-2 scale on how accurate their recall was of their memory.

Q

What was Rimmele et als test on flashbulb memories?

A

“Remember-Know test”. Showed people 60 pictures (30 neutral, and 30 negative). An hour later, showed people the same 60 pics plus 60 new ones. Asked whether they specifically remembered (episodic) seeing the photo, knew (semantic) they had seen it before, or if it was a new picture. If they “remembered” they were then asked what colour the border was.

Q

What were the results of Rimmele et als test?

A

People were more likely to “remember” emotional images and also had a higher confidence that they had seen them before. BUT emotion did not enhance memory for details-people were better at remembering the border colour for neutral pics.

Q

What was the conclusion from all the tests on flashbulb memory?

A

It’s not that special-we think we remember more, but number of details is no better. People are more likely to remember something due to emotions and stories are more congruent due to narrative rehearsal.

Q

What is the famous overnight experiment?

A

All people in the experiment read a bunch of non-famous names. After, they were told the names were not famous people. Then they were tested (pick out the famous names and non-famous). Then, tested 24 hours later, and suddenly, the non-famous names became famous!

Q

Why did the results from the famous overnight experiment happen?

A

Because the people hadn’t encoded the names into their long-term memory, but they knew they had heard the names before-assumed they must be famous people.

Q

What was Marsh et als experiment on inferential reasoning and stereotypes?

A

Participants asked to read a series of statements; some were more stereotypically male or stereotpyically female. Participants are later told that “Pat” is female, and “Chris” is male (or vice versa). When tested later, they were more likely to associate the male with the more masculine sentence, even if the male speaker was not associated with the male sentence.

Q

What is the Deese-Roediger-McDermott Paradigm?

A

When remembering whether a word was present in a list or not, there was a critical lure added in related to the context of the correct words, but that wasn’t present initally. BUT 87% of people remember seeing the lure.

Q

What are the 3 explanations of misinformation?

A

1) Source misattribution 2) Retroactive interference 3) Memory replacement

34
Q

What is source misattribution?

A

2 pieces of info: what we saw vs what we were told. Asks what was the source of each memory (not well supported)

35
Q

What is memory replacement?

A

Suggests that later info overwrites the first one-how? Reconsolidation

36
Q

How does reconsolidation work in memory replacement?

A

Crystallization in LTM does not always happen-when memory is brought back into STM it becomes fragile again and malleable.

37
Q

Is there good evidence for retroactive interference? why or why not?

A

No, because it’s difficult to test.

38
Q

How did Nader et al test memory replacement with reconsolidation?

A

With rats! Rats learned a fear tone. On the second day, they were injected with anisomycin, on the third day, rat was shown to still respond to tone, due to anisomycin being injected after consolidation
2nd condition- Anisomycin was injected on day 1, day 2 nothing happens, day 3, rat hasn’t learned
3rd condition- Day 1: tone and shock. Day 2: tone-rat freezes (consolidation). Inject them after consolidation but during reactivation Day 3: no freezing, memory was unlearned.

39
Q

How was the reconsolidation technique used to treat patients with PTSD?

A

Alain Brunet used this idea with the drug Propanolol (actively blocks stress hormone receptors) during reactivation. Drug group had a much lower stress response later when asked to relive their experiences.

40
Q

Who was Gary Graham and why is he important?

A

Executed in the USA, NO DNA EVIDENCE to convict. The only solid evidence was a single eyewitness testimony who identified him out of a lineup (she was the only one who ID’d him out of a bunch of other witnesses). Jury was also told Graham had a gun siimilar to the perpetrator, but his gun did not discharge that night (They weren’t told this last fact). He was innocent.Shows that eyewitness testimony is hella unreliable.

41
Q

What is the innocence project?

A

Assists prisoners who could be proven innocent by DNA testing-ove300 people exonerated, 18 who were on death row. 75% of these false convictions were due to eyewitness testimony.

42
Q

What are the factors that can influence eyewitness testimony?

A

Errors in attention, errors in familiarity, errors due to suggestion,errors due to post-event questioning.

43
Q

What are errors in attention and an example?

A

High stress situations affect what we attend to-example is weapon focus; tendency of the witnesses to remember more details about the weapon than the person holding it.

44
Q

What was Stanny and Johnson’s experiment on weapon focus?

A

Video of a simulated crime where in one condition the people saw the perpetrator fire a gun into the air, and another group only saw him brandish. Results were that memory for the weapon is best and group A had worse memory for all details. Shows that emotional content leads to poorer memory.

45
Q

What are errors due to familiarity?

A

Type of source monitoring error. Face seems familiar, get mixed up when deciding where we’d seen them.

46
Q

What was Ross et als study on errors due to familiarity?

A

Showed videos of teachers reading to students. Group A had a male teacher, group B a female. Then, was shown video of the teacher getting robbed, and asked to identify the robber out of a lineup (robber was either present or not). 60% of students who saw the male teacher prior identified him as the robber, 20% if they had had the female. They even identified the male teacher (less than 20%) if the actual robber was present.

47
Q

What are errors due to suggestion?

A

Subtle changes in wording can influence our interpretations and memory ex: Did you see a/the white car? Which of these people did it versus is the person who did it in the lineup?

48
Q

What is the post-identification feedback effect?

A

Increase in confidence due to confirming feedback after making an identification

49
Q

How did Wells and Bradfield study the post-identification feedback effect?

A

Had people view a video of a crime, then asked them to pick the perpetrator (real one not part of lineup), then received either confirming, no feedback, or negative. Later, they were asked to rate their confidence.

50
Q

What were the results of confidence ratings from Wells and Bradfields study?

A

Confirming: 5.4/7. None: 4.0/7. Negative: 3.5/7.

51
Q

What do errors due to post-event questioning often have to do with?

A

The misinformation effect.

52
Q

What did Chan et al ask about the misinformation effect and how did they test?

A

Can rehearsal negate misinformation effect? Had participants watch an episode of 24. Group A: Got a test on the episode afterwards. Group B: Played tetris. Everyone then hears a description of the episode with some incorrect information.

53
Q

What were the results of Chan et als study?

A

Group A: 50% of them recalled the incorrect information. Group B: 30 % recalled the incorrect information

54
Q

What is the reverse test effect?

A

Taking a recall test immediately after increase susceptibility to misinformation-taking the test brings memories back into STM making them malleable.

55
Q

How can we correct the issue of false eyewitness testimony?

A

Inform witnesses that none of the above is a valid option, (42% decrease in false ID), have a blind investigator (can’t provide feedback), immediate confidence ratings, improve interview techniques, sequential presentation of lineup, multi-modal presentations, recordings.

56
Q

What is the cognitive interview technique?

A

Recreates emotions, visualize scene from all vantage points-get 25-60% more correct information

57
Q

What is sequential lineup presentation and how does it help?

A

Have all potential people walk in one at a time rather than lining them up all at the same time- discourages choosing the “most similar” person. Decreases false ID from 43% to 17%

58
Q

How do we use fillers to decrease the chance of false ID?

A

Use fillers similar to suspect. When suspect is present- it decreases identification from 71%-58% BUT, when absent, false identification decreases from 71%-30%

59
Q

What are cross-racial errors?

A

People are better at making same-race judgements.

60
Q

What is multi-modal presentation?

A

Using voice, gait, etc as well as physical appearance to identifiy.

61
Q

How would recording the procedures help reduce false identification?

A

Allows expert witnesses to evaluate reliability

62
Q

How many things can induce bias?

A

Over 12

63
Q

What are false memories?

A

Remembering something that did not occur, incorrectly recalling details of an event.

64
Q

What was Hyman et als study on implanting false memories?

A

Got descriptions from research participants parents about real childhood stories. Gave short description of story to the participant and asked them to elaborate. Some stories were true, and some were made up. By the second interview, 20% of people recalled memories about an event that didn’t even happen.

65
Q

What was the “lost in the mall” study?

A

Loftus and Pickerell- Again, asked families for true stories that were not part of family folklore or traumatic events. Made sure the child was never actually lost in the mall. Subjects were told research was on childhood memory, also were told to be honest if they couldn’t recall. Asked participants to recall the time they were lost in the mall-incorporated plausible details into story (name of mall etc). 25% of people remembered being lost in the mall. At the end of the study, people were told that 1/4 events had not happened, and 25% of people identified the mall as being the false story.

66
Q

How did Wade, Garry, and Lindsay study false memory?

A

Asked the family for childhood pictues and doctored one of them (2 real pics, 1 doctored hot air balloon photo). Asked to provide descriptions about the photographs. By the third session, 1/2 of the participants remembered a hot air balloon ride that never happened.

67
Q

How did Braun, Ellis, and Loftus study false memories?

A

Experiment 1: Had people look at an advertisement for Disney land describing shaking Mickey Mouse’s hand. Participants were encouraged to imagine themselves in that situation. Then, tested memory for shaking Mickey’s hand before and after imagining. The experimental group who were initially uncertain became SURE that they had met Mickey and shook his hand.

68
Q

What is imagination inflation?

A

By imagining events, we become more convinced that it is real.

69
Q

What was Braun, Ellis, and Loftus’ second experiment on Disney?

A

Altered another disney ad that describes shaking Ariels hand as a child (impossible, movie hadn’t been released). Also had an ad describing shaking Bugs Bunny’s hand (Bugs bunny is not disney). Encouraged to imagine it. Results were that the 10% of the Ariel group remembered meeting Ariel, and 17% of the Bugs Bunny group remembered meeting him.

70
Q

What were the conclusions from the 2 studies done by Braun, Ellis, and Loftus?

A

Visual imagery can induce false memories for impossible events.

71
Q

What are recovered memories?

A

Memory for a traumatic event that is suddenly retrieved after being blocked for a long period (Repressed memories).

72
Q

What is the difference between the recovered memory perspective and the false memory perspective?

A

Recovered- people can repress traumatic experiences for years, especially if abuser is close/trusted
False- Memory is susceptible to suggestion-accuracy should be open to suggestion

73
Q

When did memory recovery begin to become a problem?

A

80s and 90s

74
Q

Who was Beth Rutherford and what happened to her?

A

Sought counselling for work-related stress at age 19 through a church counsellor. Counsellor believed her stress was a manifestation of abuse during childhood. Beth initially claimed this was wrong but was later convinced (2.5 years later) that she had been sexually abused by her father (claimed he impregnated her and performed coat hanger abortions). Beth later retracted accusations, but the investigation still ensued and it was found that it was literally impossible for Beth to have undergone that.

75
Q

What is one of the main arguments for recovered memories?

A

False memory studies often use emotionally neutral memories-much harder to implant memories of abuse. Some cases of known childhood abuse are not recalled as adults.

76
Q

What is Betrayal Trauma?

A

Children are dependent on adults, and in order to maintain this attachment, child inhibits memory of abuse by trusted adults.

77
Q

How can we tell true from false?

A

Confidence, details, emotional content, persistence, and neuroimaging.

78
Q

How was confidence tested?

A

Sporer et al: Eyewitnesses were asked for confidence ratings-weak correlation between confidence and accuracy
Dunning and Perretta-Used speed to identify as proxy for certainty- if someone identified in under 12 seconds, they were 90% correct. Longer, 50% accurate. Recent work shows high variability.

79
Q

How were details tested?

A

Lost in the mall study-fewer words used to describe the false memory compared to the true one-but with stronger manipulation, level of detail can exceed that of the true memory.

80
Q

How was emotional content tested?

A

Laney and Loftus implanted negative emotional memory of witnessing parents in a physically violent fight. Results showed that emotional content can be implanted!

81
Q

How was persistence tested?

A

Simple misinformation study (like cars that bumped or smashed). Tested 1.5 years later, false memory persists just as well as real.

82
Q

How was neuroimaging used to test false memories?

A

Stark, Okado, and Loftus- Misinformation study. True info was given visually, and false auditorily. Results were there was slightly more visual activation for true information and slightly more auditory for false.
