  1. PRESENTING The Atkinson-Shiffrin Model of Memory It states that we have 3 memories: Sensory Memory, Short-Term Memory, and Long-Term Memory.

  2. These memories differ in terms of 3 characteristics: • Capacity: how many units of information can be held at one time. • Duration of Storage: how long the information can be held. • Reason for Forgetting: storage failure versus retrieval failure.

  3. Long-Term MemoryRelatively permanent storage of information • Capacity: virtually unlimited. It contains 2 general kinds of information:

  4. Long-Term Memory Contains... Declarative Memory: Information you can describe Nondeclarative Memory: Information you cannot describe Semantic Memory: General information Episodic Memory: Personally experienced events Skilled actions Habits

  5. Long-Term MemoryRelatively permanent storage of information • Capacity: virtually unlimited. • Duration of Storage: up to a lifetime. • Reason for forgetting: retrieval failure (e.g., interference).

  6. Sensory MemoryTemporary storage of information • Capacity: large; contains most details of sensory input. • Duration of Storage: visual: 1/10 second; auditory: 2 seconds. • Reason for forgetting: storage failure (e.g., decay).

  7. Short-Term MemoryBrief storage of information currently being used • Capacity: 7 units, plus or minus 2. • Duration of Storage: less than 30 seconds without rehearsal. • Reason for forgetting: storage failure (e.g., decay, displacement).
