Chap 18: Memory Flashcards
What are the 3 main types of long-term memory ?
- Implicit
- Explicit
- Emotional
What are 2 kinds of explicit memory ?
Episodic and semantic
What is declarative vs semantic memory ?
Declarative
- episodic memory of events that happened
Semantic
- Memory of facts and knowledge
What is the importance of autonoetic awareness ?
- provides a sense of self-knowledge throughout time
Describe Tulving’s patient KC
- lacked autonoetic awareness from dense amnesia
- knew many objects and faces concerning his life like his date of birth, and had knowledge on school subjects like math and geography
What brain region was affected in patient KC ?
- lesions to the medial temporal lobes
What brain regions are responsible for explicit memory ?
- the cortex
- the prefrontal cortex: left for encoding, right for retrieval
- the medial temporal lobes: left temporal damage results in verbal deficits vs right side damage results in non-verbal deficits
What is another name for implicit memory ? Describe it
Procedural memory
- the acquisition of skills and habits
What brain regions are important for implicit memory ?
- the cortex
- the basal ganglia
- motor cortex
- hippocampus
What is the role of the cerebellum in implicit memory ?
Plays a role in classical conditioning
What are the role of neurotransmitters in implicit memory
- loss of cholinergic cells are related to amnesia in Alzheimers
- loss of serotonergic and cholinergic cells lead to profound amnesia
What is emotional memory ?
emotionally arousing experiences that spark vivid memories
What brain region is important for emotional memory ?
the amygdala
What is short term/working memory?
retention for basic cognitive activities like sensory events, movements, information like digits, words, names etc.
What is the role of the parietal and frontal lobes on working memory ?
Parietal
- damage causes inability to repeat verbal stimuli like digits, words, letters, sentences
frontal
- would inhibit patient on tasks where they must remember locations of stimuli
