     Cognitive Psychology
Study of thinking processes
Based on computer metaphor i.e. we try to
understand the mind by comparing it to a
computer:

   Input        Processing      Output




                 Storage

             Memory
How many different memory stores do
people have?
How do they differ from each other?

Serial position experiment
PPs hear a list of words. Asked to recall
them in any order (free recall)
   Cond 1: immediate free recall
   Cond 2: free recall after interference task
To obtain results, plotted position of each
word in the list against how many of the
PPs recalled it
                                                                      www.psychlotron.org.uk

% recall by PPs




                                                            interference
                                                                task




                                                               With
                                                           interference
                                                               task


                           Position in word list

Results:
   PPs recalled more words at beginning
    (primacy) and end (recency) of the list
   The interference task removed the recency
    but not the primacy effect
Implies that primacy words were stored
somewhere different to recency words
We have two separate memory stores

               STM & LTM
STM and LTM differ in a number of ways
including:
   Function (what they are used for)
   Capacity (how much info they can hold)
   Duration (how long info can be held for)
   Encoding (the form in which info is stored)
   Forgetting (how info is lost from storage)
