Final Exam Flashcards
Memory processes involved:
Encoding
Storage
Retrieval
Encoding
Initial acquisition of information
Storage
Info stored for future use
Retrieval
Use of stored info
Sensory memory
Momentary storage of information less than 2 seconds
Sensory memory
- iconic memory
- echoic memory
Iconic memory
Brief photographic memory
Echoic memory
Brief memory for auditory stimuli
Short term memory
- brief duration 15-30 seconds
- limited capacity
- stored by meaning, not sensory stimuli
Working memory
Involves conscious, active processing of incoming auditory and visual spatial information, and of information retrieved from long - term memory
Automatic processing
Like space , time , frequency
Miller’s experiment
7+- 2 items ( or chunks of information)
Chunking
Meaningful unit of information that may be composed of smaller units
Rehearsal
Review of practice material while you are learning it; transfers material from short term to long term
Maintenance rehearsal
Rote repetition of material in order to maintain its availability In memory
Elaborate rehearsal
Association of new information with already stored knowledge and analysis of the new information to make it memorable
Deep processing
When encoding information, processing of meaning rather than physical or sensory features of stimulus
Mnemonics
Strategies and tips for improving memory, such as the use of a verse or a formula
Explicit ( declarative)
Memories that are conscious of “ knowing that”
Semantic memory
Memory for general knowledge and facts
Episodic memory
Memory for biographical details of our individual lives ( personal experiences and context they occurred in)
Implicit ( non - declarative )
Memories we are not aware of for the performance of actions of skills
Procedural (“knowing how”)
Memory for performance of actions or skills
Serial position effect
Tendency for recall of the first and last items on a list to surpass recall of items in the middle of the list
Primacy
Items presented early in a list are remembered better
Recency
Items presented late in a list are remembered better
Memory retrieval
Retrieval refers to getting information out of the memory store
Explicit memory
Conscious, intentional recollection of am event or item of information
Recall
The ability to retrieve and reproduce from memory previously learned material
Recognition
Ability to identify previously encountered material
Memory
Refers to the capacity to retain and retrieve information, and also to the structures that account for this capacity
Why do we forget?
An inability to retrieve information due to poor encoding , storage , or retrieval
Causes to forget:
- brain never encoded it originally
- processing in STM, no transfer to LTM
- overload
- forget insignificant things so we can remember significant things
Decay theory
Theory that information in memory eventually disappears if it is not accessed
Retrieval failure
Although the information is retained in the memory store, it cannot be assessed
Tip-of - the - tongue (TOT)
Retrieval failure phenomenon. Given a cue
Interference
Similar item interfere with one another
Retroactive interference
When recently learned material interferes with the ability to remember similar material stored previously
Proactive interference
When previously stored material interferes with the ability to remember similar, more recently learned material
Source misattribution
The inability to distinguish an actual memory of an event from Information you learned about that event elsewhere
