Chapter 17: Learning & Memory part 1
What is learning?
the process of acquiring new info, behav, abilities as a result of pratice, study or experience
What is memory?
1. the ability to retain/retrieve info due to encoding (from learning)
2. specific info absorbed in the brain
Who is patient H.M?
a patient with damage to medial structures who as a result was unable to encode new declarative memories.
What is amnesia?
severe impairment of memory
What is retrograde amnesia?
inability to retrieve memories formed before the onset of a disorder
What is anterograde amnesia?
inability to form new memories since onset of disorder
What is delarative memory?
a memory that can be stated or described. H.M & N.A were not able to form new declarative memories.
What is nondeclarative or procedural memory?
memory that cant really be described but shown by performance. e.g. riding a bike. H.M. was capable of this form of memory.
Who was patient N.A.?
a patient who ccouldnt encode new declarative memories. he had damage to the dorsal thalamus and the mammillary bodies.
What is Korsakoff's syndrome?
a memory disorder related to thiamine deficiency associated with chronic alcoholism. Commonly will confabulate.
What does it mean to confabulate?
to fill in a gap with a falsification, often seen in Korsakoffs
Who was patient K.C?
a patient with dmg to the cortex who couldnt form or retrieve episodic memories especially autobiographical memories.
What is episodic memory?
memory of a particular incident of a particular time and place.
What is semantic memory?
generialized memory e.g. word meanings for which you dont know where or when you learned that word
What is skill learning?
learning to perform a task requiring motor coordination
what is priming?
exposure to a stimulus facilitates responses to the same or similar stimulus
what is conditioning?
learning involving the association of 2 stimuli or a stimulus and a response
What is iconic memory?
a very brief type of memory that stores the sensory impression of a scene
What is short term memory (STM)?
memory that lasts only for seconds or as long as rehearsal continues
What is working memory?
a buffer that holds memories available for ready access during performance of a task
What is intermediate term memory?
a form of memory that lasts longer than short term memory but not as long as long term memory.
What is the primacy effect?
better memory for stuff at the beginning of a list (attributed to long term memory)
What is the recency effect?
better memory for stuff at the end of the list (attributed to short term memory)
Whats a memory trace?
a persistant change in the brain that reflects the storage of memory
What is encoding?
the process in memory formation where info enters through sensory passages to short term memory
what is consolidation?
info in short term or intermediate term memory gets transferred into long term memory
What is retrieval?
stored memory is used
What is reconsolidation?
the return of a memory trace to stable long term storage after recall
