Trials of battered women who kill: The impact of alternative forms of expert evidence.

Abstract

The introduction of battered woman syndrome testimony in trials of battered women who have killed has stirred considerable debate within the psycholegal community. Much of the controversy stems from the testimony's focus on the woman's passivity, as well as its partrayal of a single profile of battered women. In light of these concerns, proposals to alter the content of the testimony (e.g., dropping the “syndrome” terminology, focus on battered women's social reality as opposed to their psychological state and reactions) have surfaced. In the present research both the woman's prior response history (passive, active) and the presence of expert testimony (battered woman syndrome, social agency, no expert control) were manipulated in a homicide trial involving a battered woman who had killed her abuser. Overall, participants, drawn from both a university (N=195) and a nonuniversity setting (N=202), rendered more lenient verdicts and provided more favorable evaluations of the defendant's claim of self defense in the presence of expert testimony (either form) compared to a no expert control. Further, these effects were more pronounced for the student than the nonstudent sample. Implications of these findings for the use of expert evidence pertaining to battered women are discussed.
