The impact of state and trait anger on processing of evidential inconsistencies

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 D 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.
