Chapter 5 Flashcards
memory
any system - human, animal, or machine - that encodes, stores, and retrieves information
information-processing model
a cognitive understanding of memory - emphasized how information is changed when it is encoded, stored and retrieved
encoding
1st basic task of memory - modification of information to fit the preferred format of the memory system
storage
2nd basic task of memory - involves the retention of encoded memory over time
retrieval
3rd basic task of memory - involves the location and recovery of information from memory
eidetic imagery
especially clear and persistent form of memory - photographic memory
sensory memory
1st of 3 memory stages - aims at preserving brief sensory impressions of stimuli
working memory
2nd of 3 memory stages - aims at preserving recently perceived events or experiences for less than a minute without any rehearsal - most limited stage
long-term memory
3rd of 3 memory stages - largest capacity and longest duration, stores material according to meaning
chunking
organizing a piece of information into a smaller number of meaningful units (chunks) - it frees up space in working memory
maintenance rehearsal
working-memory process in which information is merely repeated or reviewed to keep from being lost
elaborate rehearsal
working-memory process in which information is constantly reviewed and related to information already known
acoustic encoding
the conversion of information, especially semantic information, to sound patterns in working memory
levels-of-processing theory
the explanation for the fact that information that is more thoroughly connected to items in long-term memory will be remembered better
procedural memory
long-term memory storage for information based on “how things are done”
declarative memory
long-term memory storage for information based on facts, includes episodic and semantic memory
episodic memory
declarative memory that store events (episodes)
semantic memory
declarative memory that stores general knowledge like definitions and concepts
schema
cluster of related information that represents ideas or concepts in semantic memory, provides a context for understanding objects and events
childhood amnesia
the inability to remember events during the first 2-3 years of life
engram
physical changes in the brain associated with memory, AKA memory trace
