Q

What is sensory memory?

A
  • each sense had it’s own system (eg. iconcic, echoic)
  • the duration is short, but capacity is very large

Q

What is Emotional Conditioning?

A
  • Memories acquired through classical conditioning, - you get when smelling the aroma of favorite food truck while walking by.

25
What is storage?
maintaining information over time
26
What is retrieval?
accessing information when you need it
27
What do you need for succesful encoding?
- Attention - unless you pay attention, it won’t be encoded - Depth of processing - phonological - visually - meaning
28
What is phonological ?
- sound of voice
29
What are Mnemonics ?
- Imagery - Name of expression - Chaining
30
What is imagery?
- Attach image to help recall memory - the more bizarre, the better
31
What is name of expression?
- first letter each item in a list is re-arranged to form a list is re-arranged to form a phrase or word - please excuse my fear aunt sally
32
What is Chaining?
- development of a story or image that connects information
33
What are memory traces? (engrams)
- changes in our brain as a result of experiences
34
What is consolidation?
- process that stabilizes memory traces - like pen on paper
35
What is Retention interval ?
- time between encoding and retrieval
36
What is Retrieval ?
- process by which information is retrieved from memory
37
What is the diffrencce between aviablability and acessability?
- You know the humming of a song - the song was available, but you couldn’t access that
38
You know it's retrival when there is .....
- cued recall - giving hints - recognition - given options and recognizing
39
What are types of Encoding?
- context dependent memory - state dependant memory - Mood dependant memory
40
What is context dependent memory ?
- match in *physical* or *external* context between encoding and retrieval > *if you learn in class, you will do better than learning in a coffee shop. because you are writing the exam in class.* > > *Scuba divers who learned words under water, remember better under water* >
41
What is state dependant memory ?
- match in *internal/ mental* context between encoding and retrieval > *memorize list of words while you’re drunk, other group memorizes while sober* > > *asked to recall the list of words* > > *sober people recalled words well while sober but not drunks* > > *drunk people who recalled words sober didn’t do well, but they did well while drunk* >
42
What is Mood dependant memory?
- match in mood between encoding and retrieval
43
What are encoding failures?
- information was never learned in the first place > *trying to find a shirt that you didn't buy in the first place* >
44
What are Retrieval failures ?
- cues - tips of the tongue
45
What are Interferences?
- proactive - retroactive
46
What is proactive?
- old interferes with new > call your new partner your old partner’s name >
47
What is retroactive?
- new interferes with old > call old partner your new partner’s name >
48
What are Serial position effects ?
- probability of remembering depends on the position of items to remember - you remember the things at the begging and last, skip the middle
49
What is the Von Restorff effect ?
tendency to remember distinctive stimuli ?
50
What is Adaptive?
when you forget becasue it's - painful or embarrassing - Efficient
51
What is Amnesia ?
- Memory disorder (biologically based)
52
Who were the 7 sins of memory by?
Dr. Schacter
53
What are the 7 sins of memory?
- forgetting - transience - absent mindedness - blocking - misattribution - suggestibility - bias
54
What is transience?
as time passes our ability to access decreases
55
Who is Herman Ebbinghaus?
- used himself as a subject - studied list 30 meaningless syllabus - recalled after certain intervals have passed
56
What is Misattribution
confusing source of information
57
What is suggestibility ?
- distorted memories due to external sources - huge implications in eye testimony - cops use certain words that distort events
58
What is the Misinformation effect (Dr. Elizabeth Loftus)
> *did the car go through a yeild sign* > > *or the stop sign?* > > *she showed people a fake photo, with a yeild sign, and not a stop sign* >
59
How do verbs influence eye testimony?
- participants were asked to watch a video of two cars in an accident - responded to a number of questions - changed the verb: contacted, smashed, hit, bumped, or collided - then 1 month later, they were asked did you see broken glass
60
What is Bias?
- expectations and beliefs can distort memories - read a story about a political candidate, and you assume that they are white
61
What is stereotypical bias ?
- gender, race - age - body weight
62
What is Egocentric ?

63
What is Hindsight?
I knew it all along
64
What is Persistence?
- Memory is “stuck” in your head - unwanted memories - PTSD
65
What is an Engram?
changes in our brain as a result of experiences (memory traces)
66
Who was Karl Lashley?
- locate areas of the brain where engrams are stored - trained rats to run mazes - create lesions in the brain - focused on the cerebral cortex - Equipotential hypothesis
67
What is the Equipotential hypothesis?
another area of the brain can take over memory functions
68
What is the Amygdala?
- regulates fear and aggression - explicit and implicit memories - extinction of fear in rats - US - shock, NS - tone, UR/CR - fear
69
What is the Cerebellum
implicit memories and conditioned response
70
Which memeories are in the prefrontal cortex?
- Semantic memory - Working memory
71
What does the Hippocampus do in regard to memeories?
- codes explicit memories - difficulties with forming new memories
72
What are the two types of Amnesia ?
- Anterograde - Retrograde
73
What is Anterograde amnesia?
- brain trauma - difficulties with new information - Clive wearing
74
What is Retrograde amnesia?
- brain trauma - difficulties with old information - Ex. NFL player Scott Bolzan
