regions of the brain involved in memory Flashcards
main function of the neocortex?
storage of implicit memories
encoding
converting information into a useable form so that it can be placed and stored
storage
retention of the encoded information over time
retrieval
recovery of stored information for use when needed
chunking
grouping pieces of information together in order to increase the capacity of short term memory
maintenance rehearsal
repeated attention to information to increase duration of short term memory
elaborative rehearsal
applying meaning to information so that it can be easily retrieved from long term memory
short term memory
holds limited amount of information that is consciously being attended to
duration: 12-30 seconds
capacity: 5-9 pieces of information
sensory memory
entry point for new information from environmental stimuli
capacity: unlimited
duration: 0.2-4 seconds
long term memory
information is encoded and stored, and can be retrieved
duration: unlimited
capacity: unlimited
iconic memory
visual sensory memory
duration: 0.33 seconds
main function of basal ganglia
encodes implicit procedural memories (habituation, habits)
main function of cerebellum
encoding and storing implicit procedural memories
main function of amygdala
regulating emotional component of memory
main function of hippocampus
consolidation of explicit memories
rehearsal
doing something so that information can be retained and then retrieved
echoic memory
auditory sensory memory
stores sound for 3-4 seconds
explicit memory
memory that is consciously retrieved consisting of semantic and episodic memories
semantic
facts
episodic
personally relevant events
implicit memory
memory that does not require conscious retrieval, and is recalled effortlessly, consisting of classically conditioned and procedural memories
classically conditioned memory
fear or reflex
procedural memory
skills for things such as tying shoe lace
