unit 9 - memory, thinking, language Flashcards
memory
- any indication that learning has persisted over time
- our ability to store and recieve information
flashbulb memory
- a very important and emotional memory
- may make a very meaningful and strong memory
- ex. such as where you were during the 9/11 terrorist attacks
encoding
first stage of memory
encoding –> storage –> retrieval
storage
second stage of memory
encoding –> storage –> retrieval
retrieval
third stage of memory
encoding –> storage –> retrieval
information processing view of memory
working memory model
autonomic processing
memory that happens without effort
effortful processing
putting effort towards learning
rehearsal
- required for effortful processing
- conscious repetition
semantic memory
a memory based on definition
(ex. knowing what a chair is)
episodic memory
remembering an exact event
(like an episode of a tv show)
sensory memory
capacity, duration
capacity (how much): unlimited
duration: depends on the sense, but in essence, a split second
iconic memory: sensory memory of sight = .5 seconds
echoic memory: sensory memory for sound = 3-4 seconds
hepatic memory: sensory memory for touch = <1 second
short term memory
capacity, duration
capacity (how much): 7 +- 2 (5-9)
duration: 20 seconds
long term memory
capacity, duration
capacity (how much): unlimited
duration: could be forever
ebbinghaus curve: you forget most of what you learned, but what sticks stays for a long time
next-in-line effect
when in a group where each person speaks, you will forget the person’s speech who spoke right before yours
spacing effect
we learn better by studying in small bursts rather than in one large session
serial position effect
you will have a strong recall for items at the beginning and end of a list
semantic encoding
your strongest memories are created this way
visual encoding
encoding by the way something looks
mnemonics
ex. memory trick
method of loci
visualize each item in a different room in your house
link method
combine each item into a story
chunking
putting items into a meaningful unit
memory hierarchy
making different levels and sublevels by categories
echoic memory
sensory memory for sound
- 3-4 seconds
iconic memory
sensory memory of sight
- 0.5 seconds
hepatic memory
sensory memory for touch
- less than 1 second
long term potentiation (LTP)
current research into memories links them with the strengthening of synapses between neurons, and particularly to the release of the neurotransmitter serotonin
stress and memory
a little stress is good for storing memories, but too much stress is not
anterograde amnesia
when you remember everything before a certain event, but cannot form new memories after
explicit (declarative) memory
what is it?
- memory that you can state and prove you know
anterograde amnesia
- cannot form new explicit memories
- hippocampus
implicit (procedural) memory
what is it?
- memories that you must do an action to prove
anterograde amnesia
- can form new implicit memories
- cerebellum
