This theory was supported by Deffenbacher et al’s research. The second issue is the “weapons focus effect”; In Easterbrook’s research he predicted that attention will narrow to the source of the threat e.g the knife the man is holding therefore peripheral detail is lost e.g the details of the perpertrator’s face. This was supported by Loftus’s
