KC Episodic vs Semantic memory
Semantic memory that funerals are sad
HM learned to do the mirror tracing task over a series of days but was unaware that he had
donethe task before
Pursuit Rotor Task
• Rotating turntable
• Stylus and metal disc
• Time on target for 20 s trials
• Practice trials (15, 30, 45, 60 rpm)
• Learning (4) and memory (2) trial blocks
Miscellaneous Definitions
• Metamemory
– Koledge aout oe’s o eor, ho it orks, ho it fails to ork
• Metacognition
– Knowledge about oe’s o ogitie sste ad ho it orks
• Repetition priming
– Previous exposure to a stimulus can facilitate (or sometimes inhibit) subsequent
performance on the same information
Priming: Word Stage Completion
• Phase 1
• Present with list of words
– grape
– elephant
– door
– tools

Semantic Memory
• How do we measure aspects of semantic memory?
• What do the results of these experiments tell us?
Episodic—provide set of stimuli for learning and memory
Semantic—memory tasks involving information already known
• How do you think information is stored/organized?
• How do you think we retrieve information?
– Structure of memory
– Process of memory retrieval

Document Summary
Hm learned to do the mirror tracing task over a series of days but was unaware that he had donethe task before.

Previous exposure to a stimulus can facilitate (or sometimes inhibit) subsequent performance on the same information. Priming: word stage completion: phase 1, present with list of words. Episodic provide set of stimuli for learning and memory. An interrelated set of concepts/ body of knowledge: node. Point or location in the network representing a single concept: pathways. Semantic relatedness: distance between nodes determined by semantic relatedness, concepts close in meaning / highly related (e. g. , doctor, nurse) stored close together, concepts unrelated (doctor, truck) stored farther apart.
