A wealth of research has highlighted the susceptibility of eyewitnesses to verbal influence.
However, considerably less attention has been paid to the role of nonverbal influence in police questioning.
Under the supervision of Professor Karen Pine, Dr Daniel Gurney’s PhD evaluated the extent to which gestures can exert an influence on witnesses and skew their responses when questioned.
This research revealed that gestures can impact accurate eyewitness testimony and can be a powerful influential tool in police interviews.
