Abstract

Two experiments are reported that test the idea that jurors perceive child witnesses in terms of a 2-factor model of credibility with the factors defined as cognitive ability and honesty (Leippe & Romanczyk, 1987; Ross, Millers, & Moran, 1989). In the first experiment, 300 mock jurors watched a realistic videotaped recreation of a sexual abuse trial and rated the credibility of the child witness. Mock jurors perceived the child witness in terms of 2 factors: cognitive ability and honesty. Only honesty predicted verdict. These findings were replicated in Experiment 2 (N= 300) when only the child's testimony was presented and the perceptions of the child witness were not contaminated by the testimony of the other witnesses in the trial.
