- Factors that effect EWT
- Age
- Children
- More likely to pick a random person and make an error (Parker & Carranza)
- Adults (19-44)
- more confident in answers
- elderly
- have a poorer recall than adults over long (1 week) periods of time. (Memon et al 2003)
- Anastasi and Rhodes 2006 found that we are better at identifying people from within our own age group than people who are older or younger than us
- Children
- Anxiety
- An unpleasant emotional state where we fear that something unpleasant is going to happen.
- The relationship between accuracy and anxiety
- high levels of stress negatively impact on eyewitness recall
- Low arousal effects negatively effects the accuracy of EWT
- If we have a really high or really low emotional arousal we give a less accurate recall. the best recall performance is when we have a medium emotional arousal.
- the weapon effect
- there is evidence that in violent crimes arousal may focus witnesses on more central details such as a weapon.
- We are more likely to be anxious when we see a weapon and so we focus on it.
- Age
