Information passes through three stores: Sensory, Short-term, and Long-term.
Attention is necessary for transfer between stores.
Forgetting can occur through decay or interference.
Sensory Store: Holds information for less than one second.
Short-term Store: Holds about seven items for 15-30 seconds without rehearsal.
Long-term Store: Indefinite duration and unlimited capacity; information is retained post-rehearsal.
Coding: Sensory (sensory form), STM (acoustic), LTM (semantic).
Capacity: Sensory (limited), STM (7 items), LTM (unlimited).
Supported by extensive research.
Distinguishes between different memory types and their functions.
Too simplistic; ignores complexity of memory processes.
Does not account for elaborative rehearsal or the diversity of long-term memory.
Background: Underwent surgery in 1953 affecting his hippocampus and amygdala.
Findings:
Impaired episodic memory; inability to form new episodic memories.
Preserved procedural memory; could learn new motor skills.
Intact semantic memory; retained pre-surgery knowledge.
H.M.'s case illustrates distinct memory types and the role of specific brain regions in memory storage.
