Cognitive part 1

Cognitive part 1

1. stimulus - organism - response

2. short term memory, sensory memory, long term memory

3. sensory memory

   • icon: visual
     • shown with sterling's research (whole report)
       • all of the letters were in STM, but faded before could be transferred to STM
   • echo: auditory
     • info lasts 2- 3 seconds
     • cocktail party phenomena
       • we are aware of everything we hear b/c we are able to hear our names in a large party

4. whole report procedure

   • is you display a matrix of letter people are good at remembering the first and last

5. partial report procedure

   • 3 distinct tones for each distinct line; able to remember the line based on the tone

6. encode

   • processing info into a memory system

7. attention

   • the process in which you transfer info from SM to STM

8. limited capacity and duration

   • can only hold 4-6 chunks of info in STM
   • info only stays for about 15 seconds

9. STM evidence

   • serial position effect
     • we are likely to remember beginning and end of a list of words
     • primacy effect
       • remembering the beginning of the list; LTM
     • recency effect
       • remembering the end of the list; STM

10. H.M

    • severe epilepsy; eventually removed part of hypocampus
      • memories are transferred from STM to LTM
    • anterograde amnesia
      • inability to form new memories
    • retrograde amnesia
      • inability to form new LTM

11. consolidation

    • process by which info is transferred from STM to LTM
