Baddeley :

• Evaluating Baddeley AO3 : Evaluate Validity :

  Baddeley improved internal validity of his experiments by controlling recall difficulty : participants were asked to recall word order with words displayed throughout, reducing issues with familiarity + associations. However study lacks ecological validity as recalling word list is artificial + doesnt reflect real world memory use. To address this Baddeley made the 5th Forgetting trial and surprise stimulating real-life situations where recall is often unexpected.
• How many participants were in Baddeley's study?

  72 participants
• Why is a large sample size beneficial for generalisability?

  It averages out anomalies in results
• How does the gender mix in Baddeley's study affect generalisability?

  It increases generalisability due to diversity
• What is the issue with having only 15-20 people per group in Baddeley's study?

  Anomalies could significantly affect scores
• What type of volunteers were included in Baddeley's study?

  All British volunteers
• Why does using British volunteers increase generalisability in Baddeley's study?

  It reduces the risk of unfamiliarity with words
• How does long-term memory (LTM) function across different countries and languages according to the study?

  LTM works the same for all countries and languages
• What are the strengths and weaknesses of Baddeley's study regarding generalisability?

  Strengths:

  • Large sample size (72 participants)
  • Mixed gender representation
  • All British volunteers reduce word familiarity issues

  
  

  Weaknesses:

  • Small group sizes (15-20 per group)
  • Potential anomalies affecting results
