Psych eye witness
Psychologist | Study |
---|---|
Loftus and Palmer | Memory can be altered after the event. Video of car collision with 'smashed', 'hit', 'bumped', etc. |
Loftus | Weapon focus |
Yuille and Cutshall | More accurate under stress |
Yerkes-Dodson Law | A little stress improves memory |
Mitchell | Weapon is novelty, not threat |
AO2 of Loftus and Mitchell | Witnesses prepared to memorise. On a film, there is less fear so not ecologically valid |
Saywitz | 3-5: less detail // 8-15: less accurate // both more suggestible |
Coxon and Valentine | Elderly: less detail but not suggestible |
Three factors affecting EWT | Leading questions (distortion), anxiety, age |
