Psychiatr Psychol Law. 2016 Dec 1;24(4):594-604. doi: 10.1080/13218719.2016.1258686. eCollection 2017.

Abstract

The courtroom can be an emotional place, and these emotions may impact on a juror's ability to process and evaluate evidence. This study investigated the effects of mock-jurors' state and trait anger on the detection of evidential inconsistencies. Community members eligible for jury duty (N = 123) were randomly assigned to hear one of four audio trials differing in evidence consistency and emotion-inducing content. State anger increased endorsement of guilty verdicts, and angry mock-jurors were more careful processors of evidence, detecting more inconsistencies and recalling significantly more trial details. The results lend support to motivational theories of emotional influence on information processing.

Keywords: inconsistencies; juror decision making; state anger; trait anger.
