A psychiatric study of persons charged with arson.

A total of 29 court-referred individuals charged with arson were psychiatrically studied. From this pre-trial cohort from a large heterogeneous urban population base, a higher rate of psychosis was found than in other recent studies. However, consistent with these studies was the rarity of the diagnosis of pyromania. An important finding of this study was the substantial number of fires set by individuals who are homeless mentally disordered or substance abusing, or both.     

Battered women who kill

This study assesses acquital rates using mock jurors in cases involving a battered woman charged with killing her husband. The simulated trial format was based on actual courtroom proceedings including witness cross-examination and jury deliberation proceedings. The type of plea entered was varied and reflected either self-defense, automatism, or a hypothetical plea of psychological self-defense. The severity of abuse incurred by the defendant was also varied along with expert testimony. Jurors more frequently found the defendant not guilty when a plea of automatism was entered compared to a plea of self-defense. The frequency of acquittals following a plea of psychological self-defense resulted in more acquittals than the self-defense plea but significantly fewer than the automatism plea. The likelihood of acquittal increased under conditions of severe abuse as opposed to moderate abuse. Expert witness testimony was observed to influence verdicts during juror deliberations.     

The effects of complainant age and expert psychological testimony in a simulated child sexual abuse trial

Mock jurors viewed a videotape of a simulated child sexual abuse trial and then deliberated to a unanimous verdict. The complainant was described as either a 13- or 17-year-old female child. Jurors voted to convict more often when the younger complainant was seen, and the younger complainant was rated as more credible than the older complainant. Female jurors voted the defendant guilty more often and rated the complainant as being more credible than male jurors. Jurors voted to convict more often and rated the defendant as less credible when expert psychological testimony was specific to the case than when they were presented with either general expert testimony or no expert testimony. Jurors who saw a psychological expert testify became less accepting of child sexual abuse misconceptions than those in the no expert control condition. The implications of these findings are discussed.Millbrook Correctional Centre
