Question 108

An experiment was conducted to investigate the weapon focus effect on eyewitness testimony recall. Two groups of participants watched a video of a staged robbery. The High Anxiety group saw the perpetrator holding a weapon, while the Low Anxiety group saw the perpetrator holding a harmless object. Both groups then completed a recall questionnaire testing their memory of details from the video (with a maximum possible score of 20).
