    Study Notes

    Memory

    • Three types of memory functions: sensory memories, short-term memory or working memory, and long-term memory.
    • Selection of stimuli governed by level of arousal.

    Sensory Memory

    • Buffers for stimuli received through senses.
    • Three types: iconic memory (visual stimuli), echoic memory (aural stimuli), and haptic memory (tactile stimuli).
    • Examples: sparkler trail, stereo sound.
    • Continuously overwritten.

    Short-term Memory (STM)

    • Scratch-pad for temporary recall.
    • Characteristics:
      • Rapid access (~70ms).
      • Rapid decay (~200ms).
      • Limited capacity (7±2 chunks).
    • Examples: phone numbers, random sequences.

    Long-term Memory (LTM)

    • Repository for all our knowledge.
    • Characteristics:
      • Slow access (~1/10 second).
      • Slow decay, if any.
      • Huge or unlimited capacity.
    • Two types:
      • Episodic memory: serial memory of events.
      • Semantic memory: structured memory of facts, concepts, skills.
    • Semantic LTM derived from episodic LTM.

    Semantic Memory Structure

    • Provides access to information.
    • Represents relationships between bits of information.
    • Supports inference through inheritance.
    • Model: semantic network.

    Models of LTM

    • Semantic Network:
      • Inheritance: child nodes inherit properties of parent nodes.
      • Relationships between bits of information explicit.
      • Supports inference through inheritance.
    • Frames:
      • Information organized in data structures.
      • Slots in structure instantiated with values for instance of data.
      • Type–subtype relationships (e.g., DOG-COLLIE).
    • Scripts:
      • Model of stereotypical information required to interpret situation.
      • Script has elements that can be instantiated with values for context (e.g., script for a visit to the vet).
