This study sought to investigate the relation between expert witness likeability and juror judgments of credibility and sentencing. Two actors playing expert witnesses were trained to present themselves as high and low in likeability in a standard testimony scenario involving capital trial sentencing. The effects of extraversion and gender in mock jurors in attending to expert testimony were also examined. The dependent variables were the perceptions of the witnesses’ credibility and agreement with testimony and the participants were 210 psychology undergraduates. Likeability of expert witnesses was found to be significantly related to judgments of trustworthiness of the experts, but not related to confidence or knowledge of the experts or to the mock juror sentencing decisions. Women participants rated high likeable experts as more credible than low likeable experts; men did not. For men jurors, agreement with testimony increased as extraversion increased. However, for women jurors, agreement with testimony decreased as extraversion increased. The results suggest that likeability can be an important element of source credibility, and that attorneys and trial consultants now have an empirical foundation for addressing likeability as part of witness preparation.

Prison rape is a pervasive and serious problem affecting many male inmates in U.S. prisons. This paper reviews the literature on prison rape prevalence, victimization risk factors, and the psychological and non-psychological sequelae of prison rape. We address several areas of inquiry needed to guide research and facilitate solutions to the problem of prison rape, especially given the context and intent of the Prison Rape Elimination Act (PREA) passed in 2003 by the U.S. Congress. Mental health correlates remain to be studied; for example, the complex post-rape symptoms of prison rape survivors do not appear to be captured by current diagnostic nomenclature. To date, psychology has been largely silent on the issue of prison rape but may have much to offer in terms of describing and treating the psychological impact of victimization, documenting the personal and situational risk and protective factors associated with prison rape, and in designing programs and policy to reduce prison rape.

Despite the application of Self-Efficacy Theory (Bandura, 1977, 2000) to many areas of psychology, there is a lack of research on self-efficacy in the ability to testify in court. The present study fills this gap by incrementally developing the construct of Witness Self-Efficacy and establishing its psychometric properties. Study I featured exploratory and confirmatory factor analyses yielding a two-factor Witness Self-Efficacy Scale (WSES). The two components are Poise and Communication Style. Study II used a second data collection to show that both WSES domains possess convergent, divergent, and predictive validity relations consistent with those expected using an SET framework. Notably, WSES components predicted perceptions of witness credibility and sentencing outcomes above and beyond witness extraversion, general self-efficacy and general self-confidence. Implications for SET and witness preparation training are discussed.
