By providing vignettes with manipulated scientific evidence, this research examined if including more or less scientific detail affected decision-making in regards to the death penalty. Participants were randomly assigned one of the two manipulations (less science and more science) after reading a short scenario introducing the mock capital trial and their role as jury members. Survey respondents were told that a jury had previously found the defendant guilty and they would now deliberate the appropriate punishment. Before being exposed to the manipulation, respondents answered questions pertaining to their prior belief in the death penalty, as well as their level of support of procedural justice and science. These questions provided a baseline to compare to their sentencing decision. Participants were then asked what sentence they would impose \u2014 life in prison or death \u2014 and how the fMRI evidence presented by an expert witness for the defense affected their decision. Both quantitative and qualitative measures were used to identify how the level of scientific detail affected their decision. Our intended predictor variable (level of scientific detail) did not affect juror decision-making. In fact, the qualitative results revealed a variety of interpretations of the scientific evidence used both in favor of death and in favor of life. When looking at what did predict juror decision-making, gender, prior belief in the death penalty, and political ideology all were significant predictors. As in previous literature, the fMRI evidence in our study had mixed results with regards to implementation of the death penalty. This held true in both of our manipulations, showing that despite the level of detail in evidence intended for mitigation, jurors with preconceived notions may still disregard the evidence, and some jurors may even view it is aggravating and thus increase the likelihood of a death sentence for a defendant with such brain abnormalities.

Prior research has indicated an attractive-leniency bias for defendants in mock jury studies. However, in recent years there have been highly publicized trials of attractive women who also appear sexual, in which juror's judgements do not show support for the attractive-leniency bias.

Prior research has indicated an attractive-leniency bias for defendants in mock jury studies. However, in recent years there have been highly publicized trials of attractive women who also appear sexual, in which juror's judgements do not show support for the attractive-leniency bias. The opposite effect seems to be taking place. The present study is the first to test the Femme Fatale stereotype that seems to be producing harsher judgements of attractive and sexually appealing women who commit crime, and the interaction of the relationship to their victim. The present study conducted a 2 (Attractiveness) X 2 (Sexual Appearance) X 2 (Relationship) between subjects design. Researchers conducted an ANOVA on all variables. Results indicate that women who are perceived as more attractive and more sexual, are more likely to be found guilty of their crime.

Lucid dreaming occurs in those who become aware they are dreaming, while still in the dreaming state. Although lucid dreaming has been studied with respect to personality characteristics and as a learned cognitive skill to enhance well-being via processes such as mindfulness, less research has been conducted on relationships between lucid dreaming and emotion. I collected self-reports from a college sample of 262 participants to examine the relationships between lucidity experienced in dreams and emotion regulation, dispositional positive emotions, interoceptive awareness, and mindfulness. Pearson correlations revealed that greater lucidity experienced within dreams was significantly related to more positive emotions, greater interoceptive awareness, and greater mindfulness; however, lucidity was not related to emotion regulation. Furthermore, regression analyses revealed that greater lucidity experienced within dreams predicted more dispositional positive emotions above and beyond emotion regulation and interoceptive awareness. It is important to note that these relationships were tested across people who self-identified as lucid dreamers as well as those who identified as non-lucid dreamers. Overall, lucidity may be beneficial for anyone who recalls his or her dreams, in that higher lucidity was associated with more positive affect during waking. Positive emotions experienced during waking also may translate into greater awareness during dreaming.

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.

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.

Loss aversion manifests as a decision bias in which avoiding losses is preferred over acquiring rewards and can drastically alter an individual’s decision-making by overweighting potential losses relative to gains of equal magnitude. Consequently, individuals may require greater positive compensation to offset potential losses, exhibit contradictory choice preferences, or even avoid the decision entirely; and this behavior may be ascribed to an over-reliance on automatic, unconscious (intuitive) judgments rather than initiating analytic reasoning more capable of objectively evaluating outcomes.

Religion (specifically Christianity) is the topic of focus, as preliminary evidence suggests an individual’s intuitive inclinations positively correlate with and predict religious beliefs. Moreover, self-reported religious beliefs significantly differed as a function of inducing either intuitive or reflective mindsets. Therefore, the purpose of this experiment was to test the hypothesis that religious participants will display significantly greater levels of loss aversion than nonreligious participants.

This hypothesis extends from a previous study relating large-scale cultural and religious differences with loss aversion. While their results revealed religious orthodoxy strongly influenced loss aversion, the parameters elicited may be less stable as only two lottery questions were asked and religion was determined by cultural demographics. This study used the same design, but with a total of ten lotteries and a more detailed investigation into individual religious factors.

While loss aversion coefficients replicated the overall behavioral effect (Median θ = 2.6), independent sample, Mann-Whitney U tests did not yield any significant differences between Christian and Nonreligious participants (p > 0.05); nor did any of the religious factors examined account for a significant amount of variability.

This study attempted to add to current knowledge by further conflating the relationship between religiosity and adaptive decision strategies susceptible to errant and inconsistent behavior. While the hypotheses were unsupported, a null finding is still important, and future research re-testing this association or introducing causational designs may prove more fruitful in understanding these complex relationships.

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.

Several states within the United States have recently passed the Victim Life Photo Act, which allows prosecutors to present photographs of alleged murder victims when they were alive during the guilt phase of a trial. Critics argue that these photographs do not offer any relevant information about the crime or the defendant’s potential guilt and might bias jurors to vote guilty based on their sympathy for the victim—perhaps disproportionally so for high-status victims. Two mock trial experiments tested whether online participants who viewed alleged murder victim photographs would convict more because they increase anger, disgust, fear, sadness, and/or sympathy. Mock jurors who saw photographs of White (but not racial minority) victims while they were alive reported more sympathy for the victim relative to those who saw the same evidence without a photograph of the living victim—but the sympathy did not increase convictions (Study 1). Study 2 extended this study by testing whether the living victim photographs are more impactful in conjunction with seeing gruesome photographs of the victim after her death, creating a particularly disturbing contrast effect versus seeing the living photograph alone. Study 2 found that (a) living victim photographs on their own again had no effect on participants’ verdicts, (b) gruesome photographs on their own increased convictions through increased disgust, and (c) participants who saw both living and gruesome murder victim photographs (versus gruesome alone) were more conviction prone due to increased anger and sympathy. These studies inform current debates regarding the controversial Victim Life Photo Act: Admitting living victim photographs during the guilt phase—if presented along with gruesome photographs—can make jurors more sympathetic and angry, which can increase convictions.
