Let's Talk about Stats: Revising Our Approach to Teaching Statistics in Psychology.

Undergraduate statistics in psychology is an important, often challenging, course for students. The focus in psychology tends to be on hypothesis tests, such as t tests and analysis of variance. While adequate for some questions, there are many other topics we might include that could improve that data analytic abilities of students and improve psychological science in the long run. Topics such as generalized linear modeling, multilevel modeling, Bayesian statistics, model building and comparison, and causal analysis, could be introduced in an undergraduate psychological statistics course. For each topic, I discuss their importance and provide sources for instructor's continuing education. These topics would give students greater flexibility in analyzing data, allow them to conduct more meaningful analyses, allow them to understand more modern data analytic approaches, and potentially help the field of psychology in the long run, by being one part of the strategy to address the reproducibility problem.

Development and validation of the Attitudes Towards Police Legitimacy Scale.

Although there is a substantial body of work examining attitudes towards the police, no measure has been developed to consistently capture citizens' beliefs regarding police legitimacy. Given that police conduct has garnered a great deal of attention, particularly in the last few years, the current research sought to develop a scale measuring perceptions of police legitimacy. Across multiple studies, items were created and the scale's factor structure explored (Study 1 and Study 2), the factor structure was confirmed (Study 3a), and the predictive validity of the scale was tested (Studies 3b-3d). Results provided evidence for a reliable and valid 34-item scale with a single-factor solution that predicted multiple outcomes, including justification of a police shooting (Study 3b) and resource allocation to a police charity (Study 3c), as well as correlations with self-reported criminal activity, right-wing authoritarianism, and social dominance orientation (Study 3d). We hope this scale will be useful in the study of police legitimacy, expanding the current literature, and improving police-community relations. (PsycINFO Database Record

I Don't Like the Cut of your Jib: Perceived Facial Masculinity as a Cue to Criminality.

Previous research has established that the appearance of criminal suspects and defendants can affect subsequent legal decisions. Specifically, researchers have proposed that (1) masculine suspects are believed to commit more stereotypically male crimes (e.g., burglary), (2) masculine suspects are believed to commit more violent crimes (e.g., assault), and (3) masculinity is a general cue for committing crime. The current study sought to test these competing hypotheses regarding masculine appearance and perceived criminality. Across three studies, participants read a brief crime scenario and were asked to select out of a lineup the suspect they believed had committed the crime. Suspect masculinity and type of crime were manipulated to determine whether the degree of masculinity influenced whether participants believed they had committed the crime. Results showed that participants consistently associated masculinity with committing violent crime and showed some evidence for the general criminality hypothesis on secondary measures. These findings have important implications regarding law enforcement, eyewitness and juror bias, and legal decisions.

Spontaneous Violent and Homicide Thoughts in Four Homicide Contexts.

Although homicide remains an important topic of research, the majority of the research has focused on homicidal behavior and not homicide thoughts. Yet research into homicidal thoughts provides valuable insights into issues such as premeditation. In three experiments, we instructed participants to imagine different scenarios describing a situation where homicide and violence actually take place, but that do not contain violence or homicidal actions. We used both explicit and implicit methods to measure homicide and violent ideation. The evidence from these experiments indicates that when people imagine homicide scenarios, they think about violence at a substantial rate, but rarely consider homicide. Limitations and future directions are discussed.

Mock Juror Perceptions of Rape Victims: Impact of Case Characteristics and Individual Differences.

The purpose of the present study was to examine mock juror perceptions of rape victims based on the sex of the offender and victim (male offender/female victim vs. female offender/male victim), relationship to the offender (stranger vs. acquaintance vs. intimate partner), revictimization (no revictimization vs. revictimization), and individual differences in rape myth acceptance (RMA) and life history strategy (LHS). Participants (N = 332) read a vignette describing a forcible rape scenario and completed victim and perpetrator blame scales, the Mini-K, and a gender-neutral Rape Myth Acceptance Scale. Results indicated increased victim blame in revictimization conditions, as well as female offender/male victim conditions. A significant mediation effect of LHS on victim blame through the indirect effect of RMA was found, which is predicted from life history theory. Implications of these findings are discussed.

Exploitative and Deceptive Resource Acquisition Strategies : The Role of Life History Strategy and Life History Contingencies.

Life history strategy (LHS) and life history contingencies (LHCs) should theoretically influence the use of exploitative and deceptive resource acquisition strategies. However, little research has been done in this area. The purpose of the present work was to create measures of exploitative strategies and test the predictions of life history theory. Pilot studies developed and validated a behavioral measure of cheating called the Dot Game. The role of individual LHS and LHCs (manipulated via validated story primes) on cheating was investigated in Study 1. Studies 2a through 2c were conducted to develop and validate a self-report measure called the Exploitative and Deceptive Resource Acquisition Strategy Scale (EDRASS). Finally, Study 3 investigated life history and EDRASS. Results indicated that while LHS influences exploitative strategies, life history contingences had little effect. Implications of these findings are discussed.
