“…In a series of studies, we have used standardised stimulus materials in tightly controlled settings to address specific issues in eyewitness cognition (e.g., Sharps, Hess, Casner, Ranes, & Jones, ; Sharps, Janigian, Hess, & Hayward, ) and related areas (Sharps & Hess, ; Sharps, Newborg, Glaser, Hayward, & Scholl, ; reviewed and summarised in Sharps, ). These stimulus materials and methods were designed in collaboration with police field training officers, highly experienced and expert in modern law enforcement tactics, in order to maximise field validity.…”
