Q

Loftus and Palmer, 1974

A

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.

Q

In the car crash example, what type of misinformation is that?

Q

Stop Sign Example - What was it?

A

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

A

Most important factor in influencing juries. Research demonstrates that eyewitness memory is far more malleable than once thought

A

See all photos at the same time when making decision
Relative decision: people choose the person who most resembles their memory of the culprit

Q

Impact of positive feedback in a lineup

A

Increases eyewitness confidence, alters memory for the original events (rate original view as being better, rate that they could make out more facial details)

Q

What are the 3 sections of sins of omission?

A

Transience, Absentmindedness, Blocking

17
Q

What are the 4 sins of commission

A

Persistence, Misattribution, Suggestibility, Bias

18
Q

Omission: What is transience?

A

Loss of info from memory with the passage of time (forget the details) (lots of time = more lost)

19
Q

Omission: What is absentmindedness?

A

Don’t attend to information, no entry to retrieve later (lack of attention leads to memory distortions) (EX: forgetting where you put your keys)

20
Q

Omission: What is blocking?

A

Temporary failure to retrieve, increases with age (tip of the tongue demo)

21
Q

Commission: What is persistence?

A

The continued automatic retrieval of memories (often unwanted, PTSD)

22
Q

Commission: What is Misattribution?

A

Memory ascribed to the wrong source (EX: You thnk you learn something in class, but you actually heard it in a tiktok)

23
Q

Commission: What is suggestibility

A

False recollection (through leading question or others/ suggestion) (results: retrieval sketches matched the label) (conclusion: label influenced encoding of the memory = influences the reconstruction of memory at retrieval)

24
Q

Commission: What is Bias?

A

Our own influence on what we remember (influenced by beliefs/expectations/desires/emotions) (EX: You get into a fight with your friend at the end
of a trip. Because you are upset with your friend, in that
moment, you remember the entire vacation as being less
enjoyable than it actually was)

25
Q

Weapon focus effect

A

The presence of a weapon leads to accurate memory for related info and impaired memory for peripheral details (possible reasons: threatening nature of the gun, novelty of the gun given the current context)

26
Q

Photo bias

A

Increase in probability that a person will be recognized as the culprit due to previous exposure in a photo

27
Q

False memory theories: Fuzzy Trace Theory

A

Two memory components: Gist (overall main idea) and Verbatim (exact details)
False memory = Gist > Verbatim
(EX: DRM Paradigm: Verbatim is every word in the list, Gist is the overall idea which was sleep)

28
Q

False memory theories: Source monitoring framework

A

Reality monitoring - Attributing a memory either as a perceived external event of an internally generated event
Source monitoring: Determine the source of the event (source confusion: the inability to distinguish between the source of event memories)
