Memory (pg 198 206)-
.
s the
ability to store + retrieve information over time
three
key functions:
encoding : the process of
transforming what we perceive , think or feel into an
enduring memory
storage :
the process of maintaining information in memory over time
retrieval the process of
bringing to info that has been
previously stored
:
mind
* encoded but
memory is not exactly a combo of what we
already know
and what we learned
semantic
encoding the process of
relating new into in a
meaningful way to knowledge that is
already stored in
memory

way to memorize things
visual the
imagery encoding process of
storing new info by converting it into mental pictures
r does
the same
thing semantic coding does
organizational encoding the of info to the relationships among series
process categorizing according a
of items

ofthose
mnemonics that improve subsequent retrieval

Cont .
chunking combing :
small pieces of info into larger clusters/chunks that are more easily held in short-term
working memory : active maintenance of info in Short-term storage
#3
long-term memory :
a type of storage that holds info for hours , days , weeks , or years
anterograde the to transfer new info from the
amnesia
inability store
: short term into
the
long term store
retrograde amnesia : the inability to retrieve into that was acquired before a
particular
date ,
usually the date of an
Injury/surgery
consolidation the process by which memories become stable in the brain
↳ by thinking/talking about it and SLEEP
reconsolidation re-encoding things after retrieval
long-term potential (LTP) : a
process whereby repeated communication across the synapse between neurons strengthens
the connection ,
making further communication easier
retrieval che external information that is associated we stored information and helps bring it to mind
#
memory is
always available ,
not
always accessible
retrieval cue effective
encoding specificity principle
:
a can serve as an reminder when it helps re-create the
specific way in which information was
initially encoded
state dependent retrieval the information tends recalled the is in
process whereby to be better when
person the
same state retrieval
during encoding

ex :
sad vs .
happy
transfer-appropriate processing
:
the idea that
memory is
likely to transfer from one situation to another when the
retrieval of the situations match
encoding + contexts
retrieval induced
forgetting :
process by which
retrieving an item from
long term
memory impairs
subsequent recall of related items
trying to retrieve : takes place in left frontal lobe
