Lecture 10 Notes
Learning: change in the brain as a result of experience
i. Facts, events, skills, behavior patterns
ii. Act of acquiring information from the environment
Memory: the ability to store and retrieve the changes
Types of memory
1. Short-term
i. Seconds > hours
ii. Limited capacity
2. Long-term
i. ~24 hours
ii. Virtually unlimited capacity
3. Working memory
i. Information that is temporarily stored while we are using it
ii. Requires focused attention
Types of long-term memory
1. Declarative (explicit) memory: information that can be deliberately recalled
i. Recognized as a memory (conscious awareness)
2. Non-declarative (implicit) memory: memory demonstrated through performance rather
than recollection
i. May not be recognized as a memory (no conscious awareness)
Types of declarative memory
1. Semantic memory: memory for meanings, understandings, and other factual knowledge
2. Episodic memory: memory for a single event (usually autobiographical)
i. Flashbulb memories
Types of non-declarative memory
1. Procedural memory: memory for motor skills and
habits/routines
2. Associative learning: memory for relationships
between events
i. Classical conditioning
a. Dogs hear bell and salivate
ii. Operant (instrumental) conditioning
a. Fear conditioning
The case of H.M
i. H.M was 27 years old in 1953 and suffered from
severe epilepsy
a. 1 generalized convulsion each week plus several smaller ones every day
b. Seizures arose from the medial parts of both temporal lobes
ii. H.M underwent a medial temporal lobectomy to relieve his symptoms
