- Other factors affecting EWT accuracy
- Anxiety
- Loftus and Burns (1982)
- lab experiment called ' the weapons effect'
- stressful situations create an impaired recall
- group one waited outside a lab overheard a friendly conversation, a man walked out with greasy hands and was holding a pen
- control group
- 49% participants recalled correctly
- group 2 waited outside a lab, overheard a hostile conversation, sound of breaking glass,and man exited holding a knife and had blood over his hands
- 33% recalled correctly
- participants were then shown 50 photos and asked to identify the man
- people who witnessed a peaceful situation had a better recall
- anxiety narrows the focus on the mans face
- Age-young
- Poole and Lindsay (2001)
- participants were aged children aged 3-8
- there parents read them a story that contained elements of science demonstrations but also included novel info
- the children were then asked about the info
- a lot of the children incorporated lots of the parents story into their answers about the science demonstration
- the children were also asked to think about where they had got the info
- the older children were able to extract post- event info
- investigators have to be careful to make sure the children understand what they're supposed to do
- children cant give consent
- parents are needed so the children are with familiar people and are less susceptible to investigators effects
- age- elderly
- Cohen and Faulker (1989)
- middle aged and elderly
- shown film of kidnapping and then given an account of the kiddnapping
- half of the group were just given an account of the film others given misleading info
