Baddeley Classic Study

• Generalisability


  Baddeley did his study on only British participants - not generalisable for the wider population of the world
• Application 


  Revision for exams, info needs to be memorised semantically for it to be kept in LTM
• Reliability


  High control (3 second duration to show words in experiment) meant it was a standardised procedur, therefore good reliability
• Validity

  Internal Validity

  High controls mean we know the IV is what is effecting the DV, no extraneous variables

  Ecological Validity

  Tasks have mundane realism, so can’t be representative of the real world
• Ethics


  Trial 5 was unexpected, may have made participants distressed (Evaluation Aprehension)
• Generalisability


  Large sample - people with good or bad memories will be averaged out, meaning you can generalise from this sample
• Volunteer Sample

  People who enjoy memory tests will put themself forward, to representative of people in general
