memory

• short term memory:

  • limited capacity (5-9 items)
  • limited duration (18-30 seconds)
  • coding is usually sound
• long term memory:

  • unlimited capacity and theoretically permanent
  • Coding is semantic (the meaning of the information)
  • 3 types of long term memory: episodic, semantic, procedural
• (Long-term memory) Episodic:

  • stores information about events you have experienced, like a concert
  • information about the time, place, and emotions
  • These memories are declarative (they can be consciously recalled)
• (long term memory) Semantic:

  • stores facts and knowledge, such as capital cities.
  • not the place, time and emotions when you learnt them
• (long term memory) procedural

  • stores knowledge of how to do things like walking and swimming, cannot be consciously recalled.
• Atkinson and Shiffrin: Multistore model:

  A) sensory memory

  B) short term memory

  C) long term memory

  D) retrieval

  E) attention

  F) rehearsal

  
• Evaluations of Atkinson and Shiffrin (cons):

  1. capacity may be more than 5-9
  2. long term memory requires more than just rehearsal
  3. memory improves with age
  4. artificial testing
• Evaluations of Atkinson and Shiffrin (pros):

  1. supporting lab testing
  2. supporting case studies
