Chapter 8 - Memory Flashcards
the process involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present is:
memory
what are the three different types of memory?
- sensory
- short-term (working)
- long-term
what are the three steps of memory?
1) encoding
2) storage
3) retrieval
the translation of information into a neural code so that it can be stored for later use is:
encoding
the process by which information is retained over time is:
storage
the process of pulling information back out of your mind for use is:
retrieval
what is sensory memory?
briefly holds sensory information
the subsystem of sensory memory that decides which information is important is:
sensory registers
what are the two types of sensory registers and what do they do?
- iconic store: holds visual information
- echoic store: holds auditory information
flashing an array of letters on a screen and then having participants recall either a whole or partial report is a way of:
measuring capacity and duration of iconic sensory register
what type of memory temporarily stores and processes a limited amount of information in consciousness?
short-term memory
what is the limited capacity of short-term memory?
7 plus or minus 2 “bits” of information
what are the four ways to store short term/ working memory?
- visually
- phonologically
- semantically
- action
the method of increasing short term memory capacity where you group units into “bits” is called:
chunking
what are the two methods of increasing short term memory duration?
- maintenance rehearsal
- elaborative rehearsal
the limited-capacity system for storage and manipulation of information for complex tasks is:
working memory
how long does working memory last?
20 seconds
the “library” of memories with durable storage of past events and learned knowledge is the:
long term memory
what are the two types of long term memory?
- declarative memory
- procedural memory
the type of long term memory that can be verbalized is:
declarative memory
the type of long term memory that is focused on skills and actions is:
procedural memory
what are the two types of declarative memory?
- episodic
- semantic
episodic declarative memory is focused on ________
personal experiences
semantic declarative memory is focused on ________
general factual knowledge
the loss of ability to assimilate and retain new knowledge is:
anterograde amnesia
the loss of memory for events that happened in the past is:
retrograde amnesia
what is dissociation?
the idea that short term and long term memory are two different systems
who had a bilateral temporal lobectomy (removal of parts of the hippocampus and amygdala) which cause a decrease in epileptic seizures, but cause anterograde amnesia?
Henry Molaison
Henry Molaison was able to perform normally on intellectual assessments and working memory tests, which showed that his ___________ was intact.
short term memory
does working memory require medial temporal structures (hippocampus, amygdala, etc)?
no
true or false: declarative memory and procedural memory are a part of the same system in the brain
false
the hippocampus is responsible for what kind of memory?
declarative long term memory
who was involved in a motorcycle accident that damaged the left parietal occipital region of their brain, causing damage to short term memory?
K.F.
K.F. taught us that:
long term memory does not require short term memory to encode new information
