Encoding & storage

Encoding & storage

1. What is memory

   • the means by which we retain and reflect on our past experiences to use that info in the present.
     • memory is identity

2. What is the 3 store model?

3. What parts of the brain are involved?

   • Hippocampus: forming new memories
   • prefrontal cortex: encoding and retrieving

4. What is Sensory Memory?

   • stage of memory that registers info about the envir. and holds it for a period of time
     • automatic sensory store
       • echoic memory
         • a brief persistant sound in the auditory system
         • understand what someone says after they said it
     • visual sensory store
       • iconic memory
         • can only hold on to about 9 items at once, for a very short time; sperling

5. What is short term memory?

   • a proposed intermediate system in which info has to reside on its journy between sensory memory and long term memory
     • atkinson & shiffron

6. What is a memory span?

   • # of elements one can immediatley repeat back (7); chunking;

7. What is Baddely's Theory of working memory?

   • believed that there were limitations to short term memory model
     • memory system that provides storage for info that is currently being used in some conscious capacity

8. What are the components of working memory?

   • phonological loop
     • articulatory loop: inner voice that rehearses back info
       • articulatory suppression
         • sub vocal rehearsal is inhibited due to other info repeatedly in your mind
           • effects of anxiety on memory
   • visual spatial sketchpad
     • provides a virtual envir. for visualization & optical memory recall
       • visual cache: stores info. color & form
       • inner scribe: spatial movement and info
   • central executive
     • overseas other 2 parts
       • cooridnates attentional acivites
       • governs response
       • connects WM w/ LM
       • coordinates flow from WM to LM

9. What is the relationship between learning and practice?

   • power law of learning
     • memory performance improves as a function of practice
   • neural activity
     • long term potentiation
       • long lasting enhancement in signal transmission of neurons that reult from stimulating them synchronously
       • neurons that fire together wire together
         • biological evidence for power law
           • if you don't use it you lose it
