Unit 6 Flashcards
Memory
persistence of learning over time through the storage and retrieval of info
Encoding
processing of info into the memory system
-1st step of building a memory is sensory input
Storage
the retention of encoded info over time
-once encoded, memories are stored somewhere (usually more than 1 place) in your brain
Retrieval
process of getting info out of memory storage
-stored memories can be retrieved (with varying degrees of difficulty)
hippocampus
processes the memory and either sends it to long term storage or disposes it
-“short term memory”
flashbulb memory
a clear memory of an emotionally significant moment or event
long-term potentiation (LTP)
increase in a cells firing potential after brief,rapid stimulation
- believed to be a neural basis for learning and memory
priming
activation often unconsciously of particular associations in memory
mood-congruent memory
the tendency to recall experiences that are consistent with ones current good or bad mood
serial position effect
our tendency to recall the last and first items in a list
recency effect
tendency to recall the last item is in a list
primary effect
tendency to recall first items in a list
Atkinson + Shiffrin’s 3 stage model of memory
STAGE 1 : sensory memory
STAGE 2 : short term memory
STAGE 3 : long term memory
sensory memory
• sensory memory retention allows us to remember small, quick bits of info for a very short period of time
short term memory
• ability to hold and manipulate info over a brief period of time
- forget it can occur rapidly especially if distracted
- 5-9 items and remain in memory for about 20-30 seconds*
- increase as children get older and decreases in old age
long term memory
relatively permanent and limitless storehouse of memories
amygdala
responsible for emotional content of your memories. help store emotional memories
Karl Lashley
rats retained at least partial memory of the maze once pieces of their cortexes were cut out
Richard Thompson
complex memories are distributed while many simple reflex memories are localized
Ralph Gerard
memories seem to be electrical and physical
explicit memories
memories we try to remember
- use this throughout day
ex= remembering time of appointment or recalling event from years ago
implicit memories
those memories we form without any effort
-includes episodic memories: events of your life like an episode
- most amnesiacs still have implicit memory even if they don’t realize it
- motor or muscle memory is implicit *
rehearsal
conscious repetition of info
spacing
rehearsing info repeatedly over time
study-take a break-study…
semantic encoding
easier to remember things that have meaning
-flashbulb memories
acoustic memories
easier to remember things with sound and rhyme
