Memory

Memory

1. MSM

   • STM
     • Acoustic coding
     • 18-30 seconds
     • 5-9 chunks
   • SM
     • 250 milliseconds
     • Unlimited capacity
     • Sensory coding
   • LTM
     • Semantic coding
     • Potentially unlimited capacity
     • Hours/days/months/years

2. WMM

   • Visuo-spatial sketchpad
     • Visual cache (stores)
     • Inner scribe (records arrangement)
   • Phonological loop
     • Articulatory Process (inner ear)
     • Primary acoustic store (inner voice)
   • Central Executive
     • Controls components
     • Selectively attends and ignore stimuli
     • Retrieves info. from LTM
     • Limited capacity
   • Episodic buffer
     • Limited capacity
     • Added in 2000
     • Integrates info from other components
     • Time sequencing
     • Sends info. to LTM

3. Factors affecting EWT

   • Misleading information
   • Anxiety

4. Improving accuracy of EWT

   • Cognitive Interview

5. Types of LTM

   • Episodic
     • Recollections of events and experiences
       • 1. Timestamped
   • Semantic
   • Procedural

6. Coding, capacity and duration of memory

   • Coding
   • Capacity
   • Duration

7. Explanations for forgetting

   • Interference
   • Retrieval failure
