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 |
