Weapon focus effect
Anxiety of seeing a weapon focuses all your attention on the weapon so you won’t be able
to recall much else.

33% recognition in a high anxiety environment (knife and blood)
49% recognition in a low anxiety environment (pen with grease)
Overheard same argument but in the high anxiety group shattering glass was heard.

Thief tried to rob a gun shop.
Owner shot thief dead in front of 21 witnesses.
Only 13 participants took part in the study.
Asked to come back after 5 months to compare the police interviews.
Asked on a scale of 1-7, how have you been, how stressed are you and has anything
emotional happened to you?
Found that after 5 months the accuracy was very similar.
The areas that were less accurate were= colour, height and weight.
