Evaluators of eyewitness evidence (e.g., judges, jurors) often must determine whether an eyewitness’s identification of a police suspect is accurate or mistaken. It has recently been argued that a particular class of variables—suspect-bias variables—pose a unique threat to the reliability of eyewitness identification evidence. Unlike “general impairment” variables that generally impair eyewitness identification accuracy (e.g., poor viewing conditions, biased lineup instructions), suspect-bias variables produce a suspect-specific bias that increases the risk of confident misidentifications of innocent suspects. The goal of this research was to examine evaluators’ sensitivity to suspect-bias variables compared to general impairment variables, and to test whether sensitivity to suspect-bias differs as a function of whether the suspect-bias variable is under the control of the legal system (system suspect-bias) or outside of the legal system’s control (estimator suspect-bias). Participant-evaluators (N = 214) read eight crime vignettes paired with one of four different eyewitness variables (system suspect-bias, estimator suspect-bias, general impairment, or no-variable control) and rated the accuracy of each eyewitness. Evaluators also explained the reasoning for their accuracy rating, and their explanations were coded for mentions of procedural suggestion, eyewitness memory strength, memory contamination, and general eyewitness (un)reliability. Evaluators appear to be more sensitive to general impairment variables than to suspect-bias variables. This finding is alarming, as suspect-bias variables pose a greater threat to eyewitness reliability than general-impairment variables. Implications for the collection and evaluation of eyewitness evidence are discussed.

This study compared mock jurors' verdict decisions regarding three different insanity defenses that are used across jurisdictions in the United States' Criminal Justice System. Not Guilty By Reason of Insanity (NGRI), Guilty Except Insane (GEI) and Guilty But Mentally Ill (GBMI) all have different effects on the defendant and on the system, but little is known about how jurors' will use these different verdicts. This study used a vignette and online survey delivered through MTurk to see which of the three verdicts, if rendered, would be more preferable by the mock jurors. It was predicted that GEI (a "compromise" verdict with elements from both NGRI and GBMI) would be more favorable than NGRI (the most lenient) but less favorable that GBMI (the strictest). However, the findings indicated that lay people cannot tell the difference between the three insanity verdicts: an equal proportion of mock jurors in each condition chose the relevant insanity verdict. Limitations, implications, and future directions are discussed.

Forensic pathologists investigate unnatural or suspicious deaths in medico-legal cases and must be accurate and thorough in their analyses so that justice can prevail. This occupation, however, is immensely difficult, and mistakes can occur. These challenges are discussed here with suggestions for improvement. Implementing new technologies, better quality control, more research, and standardization of procedures are just a few of the multiple changes that can enhance forensic pathology.

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.

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.

Over the past several years, engagement and embeddedness have become popular research topics for academics and practitioners alike. Research has demonstrated associations between these constructs and a variety of predictors and outcomes. Prior research has not, however, placed enough emphasis on the roles of employee type, industry type, and work setting in determining predictors and outcomes. Additionally, the relative roles of engagement and embeddedness in predicting outcomes have not been thoroughly investigated. This study investigated the predictors and outcomes of engagement and embeddedness among unskilled, production line employees working in food processing in the agricultural industry by conducting a survey of employees and their supervisors. Employees answered questions about personality, motivation, satisfaction, engagement, and embeddedness while supervisors answered questions about each employee's performance. Results suggest that both engagement and embeddedness predict employee satisfaction and that engagement does so more strongly, both of which support prior research. However, results contradict prior research by suggesting that embeddedness is strongly predicted by traits internal to the employee while engagement is not, and neither engagement nor embeddedness significantly predicts employee performance. Further, the findings suggest that employees working in different settings and industries may experience work differently, and the measurements used to understand their experiences should reflect these differences.

From its founding, the United States has always claimed to be a nation of immigrants, yet in the past century the issue of immigration has become an even more contentious political issue surrounded by heated rhetoric filled with passion, but devoid of information. This thesis hopes to interrupt this rhetoric with a thorough analysis of immigration politics in Arizona through a legal lens, a theoretical lens and an empirical lens. While this thesis by no means looks at all facets of immigration politics, it informs in a manner that adds depth by providing information on the history behind, and legal arguments surrounding, the most contentious piece of immigration legislation in the United States at the moment. It then provides a theoretical analysis of how immigration legislation has created carceral networks and a panoptic gaze in Arizona specifically. It ends with a recommendation for further empirical research to partner with both the legal and theoretical frameworks. This thesis concludes that, fortified with over a century of case law, the plenary power doctrine is unwavering, and it makes federal immigration legislation an overly powerful tool in our political system from which the courts can offer little if any protection. Congress walks a fine line between preempting immigration regulation and devolving immigration regulation. SB 1070 and the 287(g) program are two contested areas of immigration regulation, which both exhibit and alter the power relationships of immigration politics in Arizona. Additionally, the application of the theories of Michel Foucault illuminates the power relationships at play in Arizona - from the power relationships among nation states in the broader political arena of geopolitics and colonialism to the face-to-face power relationship between a police officer and a stopped/detained/arrested person in a Foucauldian carceral network. This thesis ends with a call for empirical research that would yield an opportunity to analyze these relationships. This thesis discusses the importance of empirical study. It situates the study within the genre of surveillance studies and its theorists. It analyzes similar studies, and identifies the variables the most illuminating for this analysis. This thesis is written in the hope that a researcher will pick up where this thesis has left off.
