- Loftus and Palmer- Methodology
- Method evaluation (lab exp)
- strengths- controlled conditions, full control over IV (verb) so it could be changed to imply more less damage. control over confounding variables e.g time to look at material + no. of days before called back.
- low ecological validity as it was carried out in a artificial setting so its hard to generalize to real life situations
- validity
- experimental v- was high as the order of the film clips and critical q's was varied to make sure it wasn't due to order effects but due to the I.V
- also critical Q. was hidden in a no. of other questions to reduce D.C
- ecological v. was low as they didn't view a real life accident just film clips. if they viewed a real life accident it may have motivated them to observe + recall events more accurately
- experimental v- was high as the order of the film clips and critical q's was varied to make sure it wasn't due to order effects but due to the I.V
- sample bias
- EXP 1- only had 45 participants who were all american=ethnocentric and all students= social experience bias.
- EXP 2- had larger sample of 150 so more representative but also all american = difficult to generalize beyond america
- EXP 1- only had 45 participants who were all american=ethnocentric and all students= social experience bias.
- practical applications
- Method evaluation (lab exp)
