Chapter 7: Memory Flashcards
Memory
The capacity to store and retrieve information in order to facilitate learning.
Encoding
The process of taking information from the world, including our internal thoughts and feelings, and converting it to memories.
Storage
The maintenance of information in the brain for later access.
Retrieval
The process of bringing to mind previously encoded and stored information.
Multistore model of memory
A model proposing that information flows from our senses through three storage levels in memory: sensory, short term, and long term.
Sensory memory
A storage level of memory that holds sensory information on the order of milliseconds to seconds.
Short-term memory
A storage level of memory where information can be held briefly, from seconds to less than a minute.
Long-term memory
A storage level of memory where information can be held for hours to many years and potentially a lifetime.
Iconic memory
A rapidly decaying store of visual sensory information
Echoic memory
A rapidly decaying store of auditory sensory information.
Chunking
The process of grouping stimuli together in chunks in working memory to increase the amount of information stored in short-term memory.
Working memory
A component of memory that allows for both the short-term storage and manipulation of information in real time.
Rehearsal
The holding of information in the brain through mental repetition.
Amnesia
The loss of memory due to brain damage or trauma.
Anterograde amnesia
The inability to transfer information from short+term to long-term memory, preventing new long-term memories from forming.
Retrograde amnesia
A form of amnesia in which access to memories prior to brain damage is impaired, but the individual can store new experiences in long-term memory.
Levels of processing
The multiple levels at which encoding can occur, ranging from shallow to deep.
Shallow encoding
Encoding based on sensory characteristics, such as how something looks or sounds.
Deep encoding
Encoding based on an event’s meaning as well as connections between the new event and past experience.
