  • By emphasizing the role of leading questions in memory retrieval.
  • By challenging the accuracy of memory in eyewitnesses. (correct)
  • By confirming the high reliability of memory in court testimonies.

    • Which design did Loftus and Palmer (1974) use in their experiments on eyewitness testimony?

  • Independent measures design (correct)
  • Repeated measures design
  • Matched pairs design
  • Cross-sectional design
