Abstract

Viewing distance between an eyewitness and perpetrator during a crime has been sparsely researched in terms of how it affects eyewitness memory. It is well known that discriminability (i.e., ability to distinguish between guilty and innocent suspects) decreases as viewing distance increases (Wagenaar & Van der Schrier, 1996), but there is no consensus on how response bias (i.e., the likelihood of choosing from a lineup) changes due to viewing distance.
