Midterm 1 Flashcards
How is memory encoded?
Sensation - sensory memory - short-term/working memory - long term memory
Episodic memory
Memories for personal events
Semantic memory
Memories for facts
A: procedural
B: declarative
C: skills
D: classical conditioning
E: semantic
F: episodic
What 3 things influence encoding?
Availability of info (quality vs quantity)
Attention
Method of processing
What are 3 processing strategies?
Association
Organization
Rehearsal
Definition of misinformation
Incorrect info, usually from external sources, that may be incorporated into our memory
How does quality impact the recognition of people we are unfamiliar vs familiar with?
Poor quality does not impact recognition of people we are familiar with, but it does impact recognition of people we are unfamiliar with
What is retrieval influenced by? 5
Schemas
Misinformation
Familiarity
Context
Method of retrieval
What did Ebbinghaus show?
Forgetting occurs - transience
What are 5 possible reasons why forgetting occurs?
Encoding failure
Interference
Decay
Motivation to forget
Retrieval failure
Why does encoding failure occur?
Attention; it controls what we encode and it can be easily shifted
2 types of interference that impacts forgetting
Retroactive
Proactive
What is TOT?
Tip of your tongue
- elicits something related, but not quite and then blocks what you are trying to remember
What are 2 features that a retrieval cue must have?
Match b/w cue and desired memory
Cue must be distinctive
What is retrieval induced inhibition?
Remembering one thing causes you to forget other things
What is a forensic example of retrieval induced inhibition?
A witness repeatedly recalling some information of an event and that leads to the forgetting of other info
What time frame does most forgetting occur in?
24hrs
What is social influence? 2
Effect of those around us on our thoughts, feelings, and behaviours
The extent to which we are obedient, compliant, and/or conform
What are the 6 principles of compliance?
Reciprocity
Commitment and consistency
Social proof
Liking
Authority
Scarcity
What is reciprocity?
Feeling obligated to repay favours, even if they are uninvited
What are 2 techniques of reciprocity?
Perceptual contrast (good cop/bad cop & scare tactics)
Providing unsolicited favours
What is the door-in-the-face technique?
Asking for something large that they will not give you and then asking for something smaller so they comply
i.e confess to the murder - admit you knew the victim
Forensic techniques of commitment/consistency
Foot-in-the-door: small request which is agreed to and then bigger requests (you were at the bar, talked to victim, followed them home, etc.)
Four walls: person makes statements that are consistent and then they box themselves in
Social proof forensic examples
School shootings
Precedents (ruling a case one way b/c previous case was ruled that way)
What are 2 consequences of social proof?
Pluralistic ignorance: privately rejecting, but publicly agreeing
False social proof: people like us support something, but have ulterior motives
Techniques of liking 3
Halo effect
Similarity & familiarity
Compliments & cooperation
Forensic examples of authority 2
Impersonating a police officer
Lineup procedures (cops in uniform vs out)
What are the 3 parts of the lifespan retrieval curve?
Childhood amnesia
Reminiscence bump
Period of recency
What are possible reasons for childhood amnesia? 4
Biological maturation (synaptic pruning)
Language development (cannot rehearse w/o language)
Social cognitive
Lack of sense of self
What are the 7 memory sins
Transience
Absent mindedness
Blocking
Misattribution
Suggestibility
Bias
Persistence
Inattentional blindness
Missing important info when we are focused on something
What is unconscious transference?
Misidentifying an innocent bystander as the perpetrator of a crime possibly due to change blindness
What is contained in one’s autobiographical memory? 3
Personal history
Episodic events
Autobiographical facts (semantic info)
Which is more likely to be remembered and why?
A) a car theft witness when one was 20 and recalled at the age of 45
B) your bday party at age 2 recalled when you are 15
C) breaking your favourite mug last week
D) the drive to work yesterday
C) because it is emotional (favourite mug) and recent
The next would be D) because it is mundane, but recent
Then A) because it is emotional, but old
Order what type of event is recalled the most accurately overtime
Emotional
Rehearsed
Life changing
Mundane
Life changing
Emotional
Rehearsed
Mundane
What is absentmindedness?
We do not encode everything around us
What is the difference between change blindness and inattentional blindness?
Change blindness is the inability to detect changes unless we are looking directly at them
Inattentional blindness is focusing on something else and missing other information
How do schemas fit into the concept of blocking?
Interpreting and detecting information is different depending on our schemas
What is the relationship between source monitoring errors and misattribution?
Source monitoring errors, believing info came from one place and not another - can lead to misattribution
What memory sin does the fundamental attribution error and implicit theory of change fall under?
Bias
What is the fundamental attribution error?
Things that happen to us are due to our surroundings, but when they occur to others it is because of personal factors
What is the implicit theory of change and stability?
We like to believe that we are consistent in our attitudes and beliefs, but we are really not
What is truth bias?
We like to believe that people are telling the truth
What is the memory sin, persistence?
Inability to stop thoughts about events
PTSD
What are HSAMs?
Highly superior autobiographical memories
