memory Flashcards
define memory
the structure and processes involved in the storage and retrieval of information
what does the term structure refer to
how the brain is made up, the different parts of the brain
what does the term storage refer to
when information is kept in the brain
what does the term retrieval refer to
recalling information from where it is stored in memory
what does the term capacity refer to
how much information can be held at one time
what does the tern duration refer to
how long information can be held in store without rehearsal
what does the term encoding refer to
how information is transformed in order to be stored
what are the three types of memories
episodic
semantic
procedural
explain episodic memories
memories made from your personal experience, what you did last year for Christmas
explain semantic memories
common knowledge memories such as what a giraffe looks like
explain procedural memories
carrying out complex skills such as walking, driving etc
who researches memories
cognitive psychologists
what is information processing
the way in which information is inputted, encoded, stored, retrieved and outputted in our brains
explain the process of input
information entering through surrounding environment - through our five senses
explain the process of encoding
involves putting information into nerve impulses that our brain can recognise
explain the process of storage
the information is filled away (in schemas) to be used at a later date
explain the process of retrieval
the information is recalled from memory
explain the process of output
the information retrieved is used in someway
what is the process of forgetting called
amnesia
define amnesia
a condition that affects peoples ability to recall stored memories or form new ones
what are some factors that can cause amnesia
- brain injury
- illnesses
- neurological diseases
what is anterograde amnesia
the inability to form new memories after damage
what is retrograde amnesia
the inability to recall new memories after damage
draw out the multistore model
sensory input - sensory memory - stm - ltm
maintenance rehearsal
attention
elaborate rehearsal
retrieval
retrieval failure
what is the capacity, duration and encoding for sensory memory
- very high
- very short ( 2 seconds)
- separate senses
what is the capacity, duration and encoding for short term memory
- limited
- up to 30 seconds
- auditory information
what is the capacity, duration and encoding for long term memory
- unlimited
- unlimited
- semantically
what is meant by the decay theory of forgetting
- happens if not enough attention is paid to the information entering the sensory store
- the information breaks down
- multi store memory suggests that decay occurs if information isn’t rehearsed
