central executive is alledly the most improtant component, but the one we know least about. also EVR tumor removed and could solve problems but couldnt make deicisions (Central executive not unitary store)

no weapons= 49% accuracy, weapons= 33%
give 2 stregnths og the weapon focus stufy
highy controlled, easily repeatabel. reliable
give 2 limitatiosn of the weapong fosuc study
low eco val, high chanche of demand charactersitics
explain the follow up study to the weapon focus one
Loftus et al- speicial goggles track witness eye movements showed attention drawn to weapon not face or other things
