Bestiality, or human-animal intercourse, has been a concern of the legal and mental health communities for many years. Ancient legal codes delineated punishments for those who engaged in the behavior, denoting a moral and general societal concern surrounding bestiality dating to ancient times. Despite this longstanding interest in and legal efforts to punish humans for having sex with animals, there has been little research on the behavior. Current available research has largely been siloed based on the populations studied, making it difficult to render any firm conclusions about bestiality's prevalence, frequency, and the risk posed by those who have sex with animals...

Despite the widespread belief among the public and an increasing number of law enforcement personnel that individuals who harm animals often harm other people, the subject of animal maltreatment has received little attention from behavioral scientists. Advances in comparative neuroanatomy have highlighted the ability of animals to feel physical and emotional pain, including complex psychological reactions to traumatic events. These advances, and recent studies (however sparse) that support the notion that perpetrators of crimes against animals often commit other crimes, have arguably created an ethical and practical imperative for behavioral scientists to undertake a serious examination of animal maltreatment and potential mechanisms for responding to it...

Researchers have extensively studied the tendency of certain violent criminals to hurt or torture animals, primarily focusing on domestic abusers and serial killers. However, little is known about the extent or nature of prior animal abuse among active shooters and public mass shooters. Public mass and active shooters essentially represent a single offender type: they are people who commit rampage attacks in public places and attempt to harm multiple victims beyond a single target. The only difference is that "mass" shootings are traditionally defined as cases resulting in the death of four or more victims, while "active" shootings have no minimum threshold...

The assessment of an offender's risk of recidivism is emerging as a key consideration in sentencing policy in many US jurisdictions. However, little information is available on how actual sentencing judges view this development. This study surveys the views of a population sample of judges in Virginia, the state that has gone further than any other in legislatively mandating risk assessment for certain drug and property offenders. Results indicate that a strong majority of judges endorse the principle that sentencing eligible offenders should include a consideration of recidivism risk...

Pursuant to recent United States Supreme Court decisions in Miller v. Alabama (2012) and Montgomery v. Louisiana (2016), individuals convicted of crimes committed when they were younger than 18 and for which they received mandatory life sentences are entitled to new sentencing hearings. This study examined public perceptions of such individuals (life-sentenced juveniles, or LSJs). Study participants were 663 adults (52.3% male) ages 22-71 years (M = 36.00, SD = 11.46) recruited using Amazon Mechanical Turk (MTurk)...

Several legal interventions under the police power and parens patriae functions of the state depend partially on judgments that an individual is dangerous. Psychological research regarding risk assessment can provide relevant evidence regarding the appropriate application of these interventions. Developing, interpreting, and presenting relevant research regarding risk assessment in a manner that enhances the ability of courts to make accurate determinations of dangerousness requires clarification of the risk presented by this individual and explanation of how this person generates this risk...

Expert testimony concerning risk and its communication to the trier of fact has important implications for some of the most significant legal decisions. In a simulated sexual violent predator hearing, we examined how mock jurors interpret and use recidivism risk expert testimony communicated either categorically, using verbal labels, or probabilistically, using numeric values. Based upon the STATIC-99R, we compared mock jurors' decision-making and verdicts when we manipulated the style of risk communication across four different risk levels...

Risk estimates can be communicated in a variety of forms, including numeric and categorical formats. An example of the latter is "low/medium/high risk." The categorical format is preferred by judges and practitioners alike, and is mandated by the most commonly utilized forensic risk assessment instruments (the HCR-20 and the Static-99). This article argues against the practice of communicating risk in categorical terms on empirical and normative grounds. Empirically, there is no consensus about what level of risk corresponds to a particular category, such as "high risk...

An individual's risk for future violent behavior may be considered in various legal contexts, including civil commitment, criminal sentencing, or suitability for parole. Among the assessment tools forensic evaluators use to assess violence risk are the Violence Risk Appraisal Guide (VRAG; Quinsey, Harris, Rice, & Cormier, ) and the Historical Clinical Risk Managment-20 (HCR-20)/Historical Clinical Risk Management-20, Version 3 (HCR-20V3 ) (Webster, Douglas, Eaves, & Hart, and Douglas, Hart, Webster, & Belfrage, , respectively)...

Throughout an investigation, pieces of evidence are likely to contaminate one another, yet at trial jurors are expected to treat pieces of evidence as if they are independent. Are jurors able to understand potential evidence contamination? The present study showed mock jurors a videotaped trial simulation. Participants were randomly assigned to hear testimony regarding one piece of evidence, two pieces of independent evidence, or two pieces of interdependent evidence. The study tested the hypothesis that jurors who hear evidence that is interdependent will be just as likely to find the defendant guilty as jurors who hear about two pieces of independent evidence...

How the law regards animals reflects cultural trends that have varied widely from antiquity to the present. This article argues that cultural views of animals have shaped laws, attitudes, and practices worldwide. Whereas ancient (biblical and Mesopotamian) practices turned on economics, medieval concepts of animal culpability aligned with Christian beliefs of the primacy of humans. In medieval Europe, pets, farm animals, vermin, and insects could be held accountable for damage to persons and property. Considered entitled to due process, they were represented, tried, and punished - sometimes in public executions...

Animals have long formed an important part of human communities and served various roles in human activities. Some of the earliest human civilizations developed laws that protected animals for assorted reasons, including their economic value, religious beliefs pertaining to animals, and societal concerns about cleanliness. In the 1800s, Western thinkers began to view animals as having rights of their own and proposed legislation that changed the legal landscape regarding animal maltreatment. In the United States today there are widely varying laws designed to address the various forms of animal maltreatment...

Practitioners and researchers have long been challenged with identifying deceptive response styles in forensic contexts, particularly when differentiating malingering from factitious presentations. The origins and the development of factitious disorders as a diagnostic classification are discussed, as well as the many challenges and limitations present with the current diagnostic conceptualization. As an alternative to a formal diagnosis, forensic practitioners may choose to consider most factitious psychological presentations (FPPs) as a dimensional construct that are classified like malingering as a V code...

The confluence of developments in the assessment of animal abuse, the evolution of psychiatric nosology for the diagnosis of conduct disorder, legislative changes involving crimes against non-human animals, and the recent inclusion of crimes against animals in the FBI's National Incident-Based Reporting System, highlights the critical need for examining the forensic dimensions of animal abuse cases. We provide an overview of the research literature on these topics in the hope that forensic evaluators will have an evidence-based framework for assessing cases they encounter that include perpetration of violence against animals...

Animal hoarding has been considered a significant problem by animal welfare and law enforcement professionals for over a century. However, it has only been recognized as an indication of a mental disorder in the last decade. I review the different forms that animal hoarding can take and the current understanding of the prevalence, demographics and possible etiology of this disorder. Conventional animal cruelty laws have often been inadequate to respond to animal hoarding cases until they reach levels that may involve serious harm to animals and people...

Research on the topic of childhood animal cruelty methods and their link to interpersonal violence is sparse. Most of the studies that do exist focus only on the frequencies of different methods of childhood animal cruelty. Only two studies to date have examined the predictive nature of these methods for later violence toward humans. One of these previous studies found that drowning and having sex with animals were predictive of later human violence, while the other found that sex with animals and the age at which the offenders began committing animal cruelty were its only statistically significant predictors...

Neuroscience has already changed the understanding of how intent forms and is acted upon, how an individual's cognitive processes shape behavior, and how bio-psychosocial history and neurodevelopmental approaches provide information that has been largely missing from the assessment of intent. In this paper, we first review the state of forensic assessment of mental condition and intent, focused primarily on the weaknesses of the current approach. In Section 2, we discuss neurobehavioral forensic assessment, which is a neuroscience-based approach...

Violence in correctional facilities is an important issue for both prisoners and prison staff. Risk assessment instruments have demonstrated their accuracy in predicting the risk of (re) offending and institutional violence in psychiatric settings, but less is known about their ability to predict violent misconduct in prison. The present study applied four risk assessment instruments (Structured Assessment of Protective Factors for violence risk, Historical Clinical Risk Management-20, Psychopathy checklist - Revised, and Violent Risk Appraisal Guide) to 52 violent offenders in a Swiss prison in order to evaluate the instruments' predictive validities...

This article is a revision of an address made at the 2016 annual conference of the American Psychology-Law Society, in honor of receiving that organization's Distinguished Contribution Award. It sets forth a vision of the criminal justice system, and in particular the sentencing process, that is oriented toward preventive, rather than retributive, justice. After explaining preventive justice - a concept that in one form or another has been discussed for decades - and why it is worth revisiting at this time, the article proposes a number of hypotheses about the assumptions underlying preventive and retributive justice regimes...

Generally, a criminal statute must consist of two essential elements: a description of the forbidden act (actus reus) and a designation of a guilty mental state (mens rea). For a crime to be committed, an individual must commit the forbidden act with the culpable mental state. For any criminal act, both criminal liability and the possible punishment turn largely on retrospective judgments by legal decision-makers about what a defendant was or was not thinking at the time of committing the forbidden act. Given the central and foundational nature of this legal judgment, there is surprisingly little empirical study of how the mens rea construct functions...
