source misattribution
the inability to distinguish an actual memory of an event from information you learned elsewhere about the event
confabulation
confusion of an event that happened to someone else with one that happened to you, or a belief that you remember something when it never actually happened
explicit memory
conscious, intentional recollection of an event or of an item of information
recall
the ability to retrieve and reproduce from memory previously encountered material
recognition
the ability to identify previously encountered material
implicit memory
unconscious retention in memory, as evidenced by the effect of a previous experience or previously encountered information on current thoughts or actions
relearning method
a method for measuring retention that compares the time required to relearn material with the time used in the initial learning of the material
priming
a method for measuring implicit memory in which a person reads or listens to information and is later tested to see whether the information affects performance on another type of task
parallel distributed processing (PDP)
a model of memory in which knowledge is represented as connections among thousands of interacting processing units, distributed in a vast network, and all operating in parallel
sensory register
a memory system that momentarily preserves extremely accurate sensory information before the information fades or moves into short-term memory
short-term memory (STM)
in the three-box model of memory, a limited capacity memory system involved in the retention of information for brief periods; it is also used to hold information retrieved from long-term memory for temporary use
working memory
short-term memory plus the mental processes that control retrieval of information from long-term memory and interpret that information appropriately for a given task
chunk
a meaningful unit of information; it may be composed of smaller units
long-term memory (LTM)
in the three-box model of memory, the memory system involved in the long-term storage of information
procedural memories
memories for the performance of actions or skills ("knowing how")
declarative memories
Memories of facts, rules, concepts, and events ("knowing that"); they include semantic and episodic memories
semantic memories
Memories of general knowledge, including facts, rules, concepts, and propositions
episodic memories
memories of personally experienced events and the contexts in which they occurred
serial-position effect
the tendency for recall of the first and last items on a list to surpass recall of items in the middle of the list
maintenance rehearsal
rote repetition of material in order to maintain its availability in memory
elaboritive rehearsal
association of new information with already stored knowledge and analysis of the new information to make it memorable
deep processing
in the encoding of information, the processing of meaning rather than simply the physical or sensory features of a stimulus
mnemonics
strategies and tricks for improving memory, such as the use of a verse or a formula
decay theory
the theory that information in memory eventually disappears if it is not accessed; it applies better to short-term than to long-term memory
retroactive interference
forgetting that occurs when recently learned material interferes with the ability to remember similar material stored previously
proactive interference
forgetting that occurs when previously stored material interferes with the ability to remember similar, more recently learned material
cue-dependent forgetting
the inability to retrieve information stored in memory because of insufficient cues for recall
state-dependent memory
the tendency to remember something when the rememberer is in the same physical or mental state as during the original learning or experience
amnesia
the partial or complete loss of memory for important personal information
repression
in psychoanalytic theory, the involuntary pushing of threatening or upsetting information into the unconscious
childhood (infantile) amnesia
the inability to remember events and experiences that occurred during the first two or three years of life.
