Duration of Memory

Duration of Memory

1. Short-term memory

   • Peterson and Peterson
     • Lack of mundane realism
       • The task doesn't hold external validity, because remembering constants and counting back in threes is not and everyday task
         • Reduces the validity of research because it doesn't replicate everyday life
     • The ability to recall is hindered by interference rather than decay
       • Given participants a second task to complete, meant participants were unable to rehearse the letters, but also interfered with previous learning
         • This suggest the duration of the STM maybe longer without interference
     • Small Sample size
       • Methodological problem to the study, is that the sample population was only 24
         • Reducing the generalisability because it doesn't represent the target population

2. Long-term memory

   • Bahrick
   • Higher external Validity
     • Remembering a faces has higher external validity than remembering non-sense constants
       • This increases the reliability of the research conducted by Bahrick
