CPSY 4343 Lecture Notes - Lecture 5: Habituation, Dishabituation, Semantic Memory
Document Summary
Serial position effects- words remembered most when in the beginning (primacy effect) or end (recency effect) People remember more from a list of related than unrelated items. Memory organization: (1) the organization is represented as a network. Circles represent concepts: (2) activation- nodes that are in an active state are activated, (3) activation spreads, (4) the spread of activation takes time, (5) the spread of activation is limited. Attention: intentional memory tasks: instructions are to remember the items to be tested, incidental memory tasks: instructions to remember items not to be tested, adults do better on intentional (explicit) than on incidental (implicit) tasks. Other memory systems: semantic vs. episodic. Semantic memory: organized store of general information; cumulative. Episodic memory: memory for specific personally experienced events; updated frequently: explicit (declarative) vs. implicit (non-declarative) memory, hot vs. cold cognition. If the infant shows a preference, discrimination occurred. If there is no preference, you cannot conclude an inability to discriminate.
