Q

Flashbulb Memories

Study These Flashcards
A
  • Memory for the circumstances surrounding shocking, highly charged important events
  • Highly emotional, vivid, and very detailed
  • Not “photograph” memories
    • Can change with passage of time
  • Repeated recall
  • Results suggest that these memories can be inaccurate or lacking in detail
  • Narrative rehearsal hypothesis
24
Q

Repeated Recall

Study These Flashcards
A

Recall is tested immediately after an events and then retested at various times after event

25
Narrative Rehearsal Hypothesis
Idea that we remember some life events better because we rehearse them - Repeated viewing/ hearing of event - TV, newspaper, radio, talking with others - Could introduce errors in own memory
26
Constructive Nature of Memory
What actually happens+person’s knowledge, experiences, and expectations - Bartlett’s “war of ghosts” experiment - Had participants attempt to remember a story from a different culture - Repeated reproduction - Results - Over time, reproduction became shorter, contained omissions and inaccuracies - Changes to make story more consistent with own culture
27
Repeated Reproduction
Method of measuring memory in which person is asked to reproduce stimulus on repeated occasions at longer and longer intervals after original presentation of material to be remembered
28
Source Monitoring Error
Misidentifying source of memory
29
Cryptomeria
Unconscious plagiarism
30
Source Misattribution
Occurs when source of memory is misidentified
31
Illusory Truth Effect
- Enhances probability of evaluating statement is true after repeated presentation - Occur due to fluency or familiarity with the information
32
Fluency
Ease with which a statement can be remembered
33
Making Inferences
- Memory can be influenced by inferences that people make based on their experiences and knowledge - Pragmatic inferences
34
Pragmatic Inferences
Inference that occurs when reading/hearing statement leads person to expect something that is not explicitly stated or necessarily implied by statement
35
Schema
Person’s knowledge about what is involved in particular experience
36
Script
Type of schema | - Conception of sequence of actions that describe particular activity
37
Schemas and scripts influence memory
- Memory can include information not actually experienced by inferred because it is expected and consistent with the schema - Constructive nature of memory can lead to error or “false memories”
38
Highly Superior Autobiographical Memory
Autobiographical memory capacity possessed by some people who can remember personal experiences that occurred on any specific day from past
39
Nostalgia
Memory that involved sentimental affection for past
40
Music-Enhanced Autobiographical Memories (MEAMS)
Autobiographical memories elicited by hearing music
41
Proust Effect
Taste and olfaction unlocked memories he hadn’t thought of for years
42
Power of Suggestion
- Misinformation effect - Words used affects memory - Source monitoring error
43
Misinformation Effect
Misleading information presented after someone witnesses an event can change how that person later describes the event - Misleading post event information (MPI)
44
Misleading postevent information (MPI)
Misleading info that causes misinformation effect
45
Repressed Childhood Memory
Memories that have been pushed out of a person’s consciousness
46
Source monitoring error
- Failure to distinguish source of information - MPI misattributed to original source - Lindsay (1990)
47
Lindsay (1990)
- Heard a story: 2 days later again with some details changed - Told to ignore changes - Same voice for both stories created source monitoring errors - Changing voice (male to female) did not create as many errors
48
False Memories: Hyman and coworkers (1995)
- Participants’ parents gave descriptions of childhood experiences - Participant had conversation about experiences with experimenter, experimenter added new events - When discussing it later, participant “remembered” the new events as actually happening
49
Errors in Eyewitness Testimony
- One of most convincing types of evidence to a jury - Like other memory, eyewitness testimony can be inaccurate - Confidence in one’s memories may be increased by postevent questioning - May make memories easier to retrieve
50
Eyewitness Testimony
Testimony by witnesses to a crime about what they saw during commission of crime
51
Acceptance of Eyewitness Testimony
1. Eyewitness was clearly able to see what happened 2. Eyewitness was able to remember his/ her observations and translate them into accurate description of perpetrator and what happened
52
Weapon Focus Effect
Tendency for eyewitnesses to crime to focus on weapon, which causes poorer memory for other things that are happening
53
Post Identification Feedback Effect
Increase in confidence of memory recall due to confirming feedback after making an identification
54
Strategies to improve eyewitness testimony
- Inform witness that perpetrator might not be in lineup - Use “filler” in lineup similar to suspect - Use sequential presentation (not simultaneous) - Improve interviewing techniques - Cognitive Interview
55
Cognitive Interview
Procedure used for interviewing crime scene witnesses that involves witness talk with minimum interruption
