PSYA1- Memory

1. Short Term Memory

   • Capacity; How much information can remain in the memory
     • Research done by Miller
     • 7+/- 2 chunks
   • Duration; how long information can be held in memory
     • Research done by Peterson and Peterson
     • 18-21 seconds
   • Encoding; the attempt to store information for later retrieval
     • Research done by Baddeley
     • Acoustically

2. Long Term Memory

   • Duration; how long information can be held in memory
     • Lifetime
     • Research done by Barrack
   • Capacity; how much information can remain in the memory
     • Unlimited
     • Research done by Prof. Luria
   • Encoding; the attempt to store information for later retrieval
     • Semantically
     • Research done by Baddeley

3. Multi Store Model by Atkinson and Shiffron

   • Advantages
     • - the model is influential and generated a lot of other research
     • Takes long term short term and sensory memory as separate store
   • Disadvantages
     • Model is over simplified
     • More than one type of long term memory has been identified

4. Working Memory Model by Baddeley and Hitch

   • • Central Executive; in control, allocateswhere everything goes
     • Eposodic Buffer; extra storage system, retrieves info and puts it all together- limited capacity
     • Phonological Loo; contains inner ear and inner voice
       • Inner Ear; holds the words you hear
       • Inner Voice; repeats words you've heard/seen
     • Visuospatial Sketch Pad
       • Movement; relationship between things
       • Visual; what things look like
   • Strengths;
     • Doesn't over emphasise importance of rehearsal
     • Supported by studies involving brain scans
   • Weakness
     • Doesn't represent LTM just acknolodges it
     • Capacity of Central executive never measured
