the process by which we transform what we percieve, think, or feel into an enduring memory.
Term
storage
Definition
the process of maintaining information in memory over time
Term
retrieval
Definition
the process of bringing to mind information that has been previously encoded and stored
Term
elaborative encoding
Definition
the process of actively relating new information to knowledge that is already in memory.
Term
Semantic judgements
Definition
required participants to think about the meaning of the words "Is a hat a type of clothing"?
Term
Rhyme Judgements
Definition
Required participants to think about the sound of the words "Does hat rhyme with cat?"
Term
visual judgements
Definition

organizational encoding
Definition
the process of categorizing information according to the relationships among a series of items.
Term
sensory memory
Definition
a type of storage that holds sensory information for a few seconds or less
Term
iconic memory
Definition
a fast-decaying store of visual information
Term
echoic memory
Definition
a fast- decaying store of auditory information
Term
short-term memory
Definition

a type of storage that holds nonsensory information for more than a few seconds but less than a miute

 

Term
rehearsal
Definition
the process of keeping information in short-term memory by mentally repeating it.
Term
chunking
Definition
combining small pieces of information into larger clusters or chunks that are more easily held in short-term memory
Term

Definition
active maintnenance of information in short-term storage
Term
long-term memory
Definition
a type of storage that holds information for hours, days, weeks, or years.
Term

Definition
A process whereby communication across the synapse between neurons strengthens the connection, making further communication easier.
Term
NMDA receptor
Definition
a receptor site on the hippocapus that ifluences the flow of information between neurons by controlling the initiation of long-term potentiation.
Term
retrieval cue
Definition
External information that helps bring stored information to mind.
Term
encoding specificity principle
Definition
the idea that aretrieval cue can serve as an effective reminder when it helps re-create the specific way in which information was intitially encoded
Term
state-dependent retrieval
Definition
the tendency for information to be better recalled when the person is in the same state during encoding and retrieval
Term
transfer-appropriate processing
Definition
the idea that memory is likely to transfer fro one situation to anotehr when the encoding context of the situations match.
Term
retrieval-induced forgetting
Definition
A process by which retrieving an item from long-term memory impairs subsequent recall of related items.
Term
explicit memory

transience

proactive interference
Definition
situations in which information learned earlier impairs memory for information acquired later.

Term
prospective memory

blocking
