  • Memory
    • coding capasity & duration
      • coding- acoustical in STM and semantic in LTM
        • Eval; atrifical stimuli
      • capasity- STM is 7 +/- 2  LTM is unlimited
        • Eval; temporal validity
      • duration- 18-30 seconds in STM and potentially forever in LTM
        • Eval; 1-artifical stimulus 2-high external validity
    • Multi store model
      • sensory register is effected by a stimulus - with attention this is captured in the STM - with prolonged rehersal into LTM
      • Eval; 1-supporting research 2- contradictory evidence 3- atirfical tesks 4- multiple type of STM
    • Working memory model
      • just explains types of STM   contains the central execuative = slave the phonological loop = sound the visuospatial sketch pad = spatial awareness and the episodic buffer = temp store before moving to LTM or being lost
      • Eval; 1-supporting brain damage 2- supporting research 2 visual tasks impossible 3- fMRI's support 4- vauge on central exect
    • types of LTM
      • Episodic- time stamped, complex, have to consciously recall semantic- facts, non personal  procedural- skills, hard to explain, unconscious
      • Eval; 1-clive wearing support 2- fMRI support 3- real life application 4-cannot genralise
    • explainations of forgetting
      • Interference
        • proactive- old>new retroactive new>old
        • Eval; 1- supporting evidence 2-atrifical task 3- real life support 4- may be exaggerated
      • Retreival failure
        • cues that help us remember memories, can be contextural= environmental or state dependant = internl state of mind
          • study done using divers demonstrated context dependent forgetting
    • Factors effecting Eye witness testimony
      • Misleading information
        • leading questions - car crash study + post event discusion - people report inforation they couldnt have physically seen
        • eval; 1- real life app 2-artifical tasks 3- indiviual differences 4- lacking external validity
      • Anxiety
        • knife study showed low anxiety better, real bank robbbery found more = found yerks dodson curve of peek anxiety
        • eval; 1- knife study inaccurate methodology 2- real robbery= low varaiable control 3- ethical issues 4- too simplistic
    • improving eye witness interviews
      • Cognitive interview
        • 5 parts to make EWT better   1- report everything 2- reinstate context 3- reverse order 4- change perspective 5- enhanced cognitive interview
        • eval; 1- some elements are helpful 2- effective 3- time consuming 4- uneffective long time after crime
