Study Notes

Memory Stages and Processes

  • Memory involves three stages: encoding, storage, and retrieval
  • Sensory memory holds information briefly, a fraction of a second
  • Short-term memory (STM) holds about 7 ± 2 items for 20-30 seconds
  • Long-term memory (LTM) stores information for extended periods

Sensory Memory

  • Iconic memory: visual sensory memory
  • Echoic memory: auditory sensory memory
  • George Sperling's experiment demonstrated iconic memory

Short-Term Memory (STM)

  • Capacity of STM is approximately 7 ± 2 items
  • Chunking improves STM capacity
  • Miller's "magic number" refers to this capacity

Long-Term Memory (LTM)

  • Episodic memory: personal experiences and events
  • Semantic memory: facts and general knowledge
  • Procedural memory: skills and habits

Levels of Processing Theory

  • Memory retention depends on the depth of processing
  • Deeper processing leads to better memory retention

Forgetting

  • Interference: new information disrupts old memories
  • Retroactive interference: new memories disrupt recall of old items
  • Proactive interference: old memories disrupt recall of new information
  • Trace decay: fading of memory traces over time
  • Retrieval failure: inability to access stored memories

Memory Disorders

  • Korsakoff's Syndrome: memory disorder linked to vitamin B deficiency
  • Alzheimer's disease: progressive brain cell loss affecting memory

Working Memory

  • Baddeley and Hitch's model includes: phonological loop, visuospatial sketchpad, and episodic buffer
  • Central executive: decision-making and attention control aspect of working memory
  • Episodic buffer: integrating information from other components of working memory

Encoding Strategies

  • Chunking: grouping items into meaningful units
  • Mnemonics: memory aids using encoding strategies
  • Visualization: creating mental images to aid in encoding

Memory Testing

  • Nonsense Syllables experiment, developed by Ebbinghaus
  • Sperling's Partial Report Experiment, demonstrated iconic memory
