Describe the suspect: Systematic sources of error in person descriptions

Abstract | Word Stems | Keywords | Association | Citation | Similar Titles



Abstract:

Person descriptions are an important initial step in criminal investigations but few studies have investigated the accuracy of witness descriptions. The usual paradigm involves briefly exposing participants to a target person and later prompting a description; generalizations and conclusions from this paradigm are limited because the targets are homogeneous and the design does not separate memory issues from systematic misperceptions. Raters (n=167) provided person descriptions for 40 models; raters and models varied widely in age, height and weight. Systematic sources of estimate error were examined via stepwise multiple regressions. The own-anchor effect was evident in height, weight and age estimates.
