Memory Flashcards
memory
retention of learning or experience
retrograde amnesia
cannot remember events prior to brain damage => loss of old memories
anterograde amnesia
cannot remember events post brain damage => no new memory
Alzheimer’s disease
patients remember things from their younger years but cannot form new memories => STM and working memory is affected, then episodic and semantic and procedural
what surgery did H.M have?
hippocamus bilateral removal => medial tempora lobes
what type of memory did HM have?
still had his short term memory but did not have encoding for long term memory => learn new skills but not acquire new facts of events
chronic alcoholism (Korsakoff’s syndrome)
amnesia caused by lack of thiamine (vit B1) => causes severe anterograde amnesia and some retrograde amnesia => affects STM but not LTM
serial position effect
people remember the first words and most recent words in a string of words
primacy effect
the first words are encoded and are recalled better than middle words in a string
recency effect
most recent words are in our working memory and are recalled better than middle words
arkinson shriffin memory model
