Description
Courthouse dogs (sometimes referred to as facility animals) are expertly trained canines which may be used to assist individuals with psychological, emotional, or physical difficulties in a myriad of courtroom situations. While these animals are increasingly used to assist young witness to court, the jury is still out on whether or not they are prejudicial to the defendant. No known research exists in this area, although research is necessary to determine the possibly prejudicial nature of these animals. Using a mock trial paradigm involving a child sexual abuse case, the current study employed a 2 (Witness type: victim vs. bystander) x 3 (Innovation type: courthouse dog vs. teddy bear vs. none) fully-crossed factorial design. It was hypothesized that witness type and innovation type would interact to differentially impact jurors' judgments about the trial, defendant, and child witness. In addition, it was posited that emotions, such as anger and disgust, would also affect judgments and decision-making. Results indicate that courthouse dogs and comfort toys did impact jurors' decision making in some ways. In addition, emotions and witness credibility predicted sentencing, verdict, and other trial judgments.

Description
This study investigates the presence of a dual identity defendant, and how sharing an in-group can create a judgment bias. A sample of 256 participants was used to test whether there was a relationship between judgment punitiveness, perceptions of shared identity, hypocrisy and the social identities (religion and sexual orientation) of the participants and a defendant charges with a sexual offence. Results suggest that Christian participants selected more punitive outcomes for the defendant compared to non-Christian participants. Further, participants were more punitive when the defendant was gay compared to when the defendant was heterosexual. Also, when the defendant was straight there was a stronger feeling of similarity between the participants and defendant compared to when the defendant was gay, and non-Christian participants had a stronger feeling of closeness to the defendant compared to Christian participants. There was a significant interaction found, suggesting that when the defendant was Christian and gay he was seen as more hypocritical compared to when he was Christian and straight; there was no interaction when the defendant was not Christian. These findings should aid in future research and a better understanding of how dual identity defendants are perceived in the courtroom.

Description
Recent advances in hierarchical or multilevel statistical models and causal inference using the potential outcomes framework hold tremendous promise for mock and real jury research. These advances enable researchers to explore how individual jurors can exert a bottom-up effect on the jury’s verdict and how case-level features can exert a top-down effect on a juror’s perception of the parties at trial. This dissertation explains and then applies these technical advances to a pre-existing mock jury dataset to provide worked examples in an effort to spur the adoption of these techniques. In particular, the paper introduces two new cross-level mediated effects and then describes how to conduct ecological validity tests with these mediated effects. The first cross-level mediated effect, the a1b1 mediated effect, is the juror level mediated effect for a jury level manipulation. The second cross-level mediated effect, the a2bc mediated effect, is the unique contextual effect that being in a jury has on the individual the juror. When a mock jury study includes a deliberation versus non-deliberation manipulation, the a1b1 can be compared for the two conditions, enabling a general test of ecological validity. If deliberating in a group generally influences the individual, then the two indirect effects should be significantly different. The a2bc can also be interpreted as a specific test of how much changes in jury level means of this specific mediator effect juror level decision-making.

Description
When children allege sexual abuse, there is rarely medical evidence or eyewitnesses, making their testimony in trial a primary factor in assessing their credibility. However, little is known about what may be unclear to jury members making verdict decisions. In some districts, jury members are allowed to ask questions of the child witness at the end of their testimony. The current study utilizes a sample of trial transcripts from Maricopa County, Arizona where children ages 5-17 years old have alleged some form of sexual abuse; a jurisdiction where jury members are permitted to ask written questions. Cases were analyzed to assess: 1) if jury questions were asked and how often these questions occurred, 2) what content they asked about, and 3) whether occurrence or frequency of jury questions related to case characteristics (i.e. child age, child-perpetrator relationship, severity of abuse, frequency of abuse). It was hypothesized that 1) juries would ask questions mostly about the dynamics of abuse and disclosure, 2) these questions would primarily clarify information previously discussed by attorneys during direct- and cross-examination (instead of asking new inquiries that went undiscussed during testimony), 3) there would be more jury questions as child age increases and 4) more serious cases (based on case characteristics) would have more jury questions. Results were mixed. Jury members often asked about the dynamics of abuse and disclosure (abuse details, statements regarding abuse, the child’s subjective reactions), but case characteristics of child age, child-perpetrator relationship, and severity of abuse did not have a relationship with the presence of jury questions. However, cases where children alleged multiple instances of abuse were more likely to receive jury questions, which may allude to the misconception that children would disclose abuse right away and not let multiple instances occur. Although the sample size is small for generalization, it is an important first step for future research to further examine jury questions, improve attorney questioning techniques, and better educate the general public about the dynamics of child sexual abuse cases.

Description
The jury is a perfect example of American democracy in action. People convicted of crimes are put before a randomly-selected jury of their peers. This jury consists of people with a variety of backgrounds and experiences without any sort of specialized training. Ideally, this jury is representative of the population and does not have any biases towards the victim or the defendant. They view all evidence, hear all facts, and ultimately decide on a verdict. However, this system does not always create accurate outcomes. Often times and for a number of reasons, jurors are distracted in the courtroom. This can lead to incorrect verdicts, meaning that either guilty people walk free or innocent people are incarcerated. This paper will explore the idea of the distracted juror and ways to minimize these distractions so that the most accurate decision can be made during a trial. It will first examine the statistics behind jury inaccuracies as well as how other countries conduct their jury trials. It will then briefly explore grand juries and their differences between trial juries. This paper will analyze data from a survey conducted at the beginning of the project. It will then provide analyses of some possible reforms. This paper will conclude with how this research could be pursued further, why it should be pursued further, and how jury trials could look in the future.

Description
There is conflicting evidence regarding whether a biasing effect of neuroscientific evidence exists. Early research warned of such bias, but more recent papers dispute such claims, with some suggesting a bias only occurs in situations of relative judgment, but not in situations of absolute judgment. The current studies examined the neuroimage bias within both criminal and civil court case contexts, specifically exploring if a bias is dependent on the context in which the neuroimage evidence is presented (i.e. a single expert vs. opposing experts). In the first experiment 408 participants read a criminal court case summary in which either one expert witness testified (absolute judgment) or two experts testified (relative judgment). The experts presented neurological evidence in the form of functional magnetic resonance imaging (fMRI) data and the evidence type varied between a brain image and a graph. A neuroimage bias was found, in that jurors who were exposed to two experts were more punitive when the prosecution presented the image and less punitive when the defense did. In the second experiment 240 participants read a summary of a civil court case in which either a single expert witness testified or two experts testified. The experts presented fMRI data to support or refute a claim of chronic pain and the evidence type again varied between image and graph. The expected neuroimage bias was not found, in that jurors were more likely to find in favor of the plaintiff when either side proffered the image, but more likely to find for the defense when only graphs were offered by the experts. These findings suggest that the introduction of neuroimages as evidence may affect jurors punitiveness in criminal cases, as well as liability decisions in civil cases and overall serves to illustrate that the influence of neuroscientific information on legal decision makers is more complex than originally thought.

Description
A substantial amount of research has been dedicated to understanding how and why innocent people confess to crimes that they did not commit. Unfortunately, false confessions occur even with the best possible interrogation practices. This study aimed to examine how different types of false confession (voluntary, compliance, and internalization) and the use of jury instructions specific to confessions influences jurors’ verdicts. A sample of 414 participants read a criminal trial case summary that presented one of four reasons why the defendant falsely confessed followed by either the standard jury instruction for confessions or a clarified version. Afterwards, participants completed several items assessing the perceived guilt of the defendant, their attitudes on confessions in general, and their opinions on jury instructions. Although the three confession reasons did not differ among one another, jurors who were given no explanation for the false confession tended to more harshly judge the defendant. Further, the clarified jury instructions did not influence the participants’ judgments. Future research should focus on how expert witness testimonies affect verdicts regarding each type of false confession reason and whether the media may influence a juror’s knowledge of factors that could provoke false confessions.

Description
In recent years, the use of biologically based (neurological, neuropsychological, genetic) evidence in criminal trials as support for claims of mental impairments among offenders has increased in popularity. However, research on how exposure to those arguments affects jury decision-making remains unclear. Specifically, arguments rooted in biology sometimes mitigate and sometimes aggravate judgments of criminal responsibility for mentally ill offenders, and this discrepancy seems to stem from the specific conditions by which that disorder was acquired. The following study’s aim was to uncover the precise mechanism(s) behind this elusive effect. Utilizing a 2x2 between subjects experimental design, participants were presented with a hypothetical crime summary involving an offender with either an onset controllable or uncontrollable mental disorder. Ratings of criminal responsibility and other variables hypothesized to function as mediators were obtained after presentation of a prime supporting either a biologically deterministic or free will argument for human behavior in general. Results indicated that when the defendant’s disorder was the result of the his own actions (onset controllable), a biological prime decreased judgments of criminal responsibility; however, when the disorder was caused by factors out of his control (onset uncontrollable), the prime increased judgments of criminal responsibility. An examination of several possible mechanisms finds the effect mediated by the perception of control the defendant could have had over his own actions at the time of the crime. These results suggest that perceptions of behavioral control are an important contributor to jurors’ formation of criminal responsibility judgments when an offender possesses a mental illness; and arguments advocating a biological basis for human behavior reliably affect blame attribution, suggesting that a societal shift in the perception of free will as a result of increased exposure to biology in general may alter the framework of criminal responsibility judgments.

Description
Research at the intersection of psychology and law has demonstrated that juror decision-making is subject to many cognitive biases, however, it fails to consider the influence of culturally derived cognitive biases. As jurors become increasingly demographically and culturally diverse it is possible—and even likely—that their attributions might vary because of their cultural background. I predict that cultural and demographic group affiliation affects attributional tendencies such that, compared to situationally focused individuals (those from East Asian cultures, women, those from lower socioeconomic status groups, and older individuals), dispositionally focused individuals (those from Western cultures, men, those from higher socioeconomic status groups, and younger individuals) are less likely to attribute some portion of causation and responsibility for the harm to other influences, and they are more likely to find the defendant liable and hold the defendant financially responsible to a greater degree. This dissertation has three aims: (1) to examine how culturally derived attributional tendencies influence jurors' assessments of causation in complex negligent tort cases where there are multiple causal influences (i.e., multiple tortfeasors and plaintiff negligence) (Studies 1 and 2); (2) to study the implications of those causal determinations on liability determinations, damage awards, and other legal decisions (Studies 1 and 2); and (3) to determine whether these culturally derived attributional tendencies are malleable, suggesting an intervention that might be used to attenuate the influence of attributional tendencies in a trial setting (Study 3). This work advances psychological research on cultural differences in attribution by exploring attributional differences in a new domain, developing a new scale of individual differences in attributional tendencies, and examining how multiple causal influences affects culturally derived attributional tendencies and downstream decision-making.

Description
The current study used the Trauma Symptom Checklist-40 (TSC-40) to index both childhood sexual abuse (CSA) and childhood physical abuse (CPA) in a college student sample of both men and women (N = 441). Although the TSC-40 was designed as a measure of CSA trauma, this study concludes the measure is appropriately reliable for indexing the traumatic sequelae of CPA as well as CSA in nonclinical samples. The current study also explored the effects of gender and abuse severity on resulting symptomatology, finding that women and severely abused individuals report the most negative sequelae. Both CSA and CPA emerged as significant explanatory variables in TSC-40 scale scores beyond gender, supporting its validity for indexing traumatic sequelae in nonclinical samples.
