For decades, researchers have found that jurors are consistently unable - or unwilling - to disregard inadmissible evidence when instructed to do so by a judge. The legal system ignores the problem entirely: judges have repeatedly affirmed that a judge’s instructions to disregard are a sufficient safeguard of defendants’ constitutional rights, regardless of whether the jury actually disregards the inadmissible evidence. This study tested four interventions derived from psychological research to identify the combination that most effectively helped jurors disregard inadmissible evidence (operationalized by lower conviction rates). It was hypothesized that the most effective interventions identified in Study 1 would yield significantly lower conviction rates when compared to traditional instructions to disregard in Study 2. The interventions were tested in Study 1 using Multiphase Optimization Strategy (MOST) methodology to identify the optimized intervention package through regression analysis. Study 2 served as a randomized controlled trial in which treatment as usual (a judge’s instructions to disregard) was compared to the optimized intervention package. Participants were randomly assigned to either (1) be exposed to no inadmissible evidence, (2) receive inadmissible evidence and treatment as usual, (3) receive inadmissible evidence, treatment as usual and the optimized intervention package, or (4) receive the inadmissible evidence without objection. Logistic regression revealed that jurors who were given an instruction to disregard produced lower conviction rates when they also received the optimized intervention package. Interpretation, limitations, and calls to action are discussed.

This study investigated the relation between Sensory Processing Sensitivity (SPS) temperament and depression, and whether such a relation might be further influenced by the indirect effects of parenting environment and empathic personal distress. A moderated mediation model was proposed to explain the underlying relations among SPS, depression, parenting environment and empathic personal distress. That is, greater levels of SPS temperament might predict higher levels of empathic personal distress, which then leads to increasing likelihood of experiencing depression. Moreover, it was predicted that this mediation relation might be significantly stronger under a less positive parenting context. The present study recruited 661 participants from a U.S. university and implemented questionnaires in an online survey. There was a significant main effect of SPS temperament in predicting empathic personal distress and depression, such that the more sensitive individuals reported higher empathic personal distress and depression. There also was a significant main effect of parenting environment on depression, where more positive parenting was associated with less depression. Empathic personal distress was found to partially mediate the relation between SPS and depression. That is, the association between SPS and depression could be partially explained by empathic personal distress. However, parenting environment did not moderate the main effect of SPS temperament on depression, the main effect of SPS on empathic personal distress, or the mediation model.

The attractiveness of a reward depends in part on the delay to its receipt, with more distant rewards generally being valued less than more proximate ones. The rate at which people discount the value of delayed rewards has been associated with a variety of clinically and socially relevant human behaviors. Thus, the accurate measurement of delay discounting rates is crucial to the study of mechanisms underlying behaviors such as risky sex, addiction, and gambling. In delay discounting tasks, participants make choices between two alternatives: one small amount of money delivered immediately versus a large amount of money delivered after a delay. After many choices, the experimental task will converge on an indifference point: the value of the delayed reward that approximates the value of the immediate one. It has been shown that these indifference points are systematically biased by the direction in which one of the alternatives adjusts. This bias is termed a sequencing effect.

The present research proposed a reference-dependent model of choice drawn from Prospect Theory to account for the presence of sequencing effects in a delay discounting task. Sensitivity to reference frames and sequencing effects were measured in two computer tasks. Bayesian and frequentist analyses indicated that the reference-dependent model of choice cannot account for sequencing effects. Thus, an alternative, perceptual account of sequencing effects that draws on a Bayesian framework of magnitude estimation is proposed and furnished with some preliminary evidence. Implications for future research in the measurement of delay discounting and sensitivity to reference frames are discussed.

This study investigated whether research by researchers affiliated with a religious academic institution would be seen as of less scientific merit than research done by researchers affiliated with a nonreligious academic institution. Such a bias may exist given the different value systems underlying religion and science, the widespread perception of a conflict between religion and science, and research on differences in cognitive styles and stereotypes about religious versus nonreligious people. In this study, U.S. participants recruited from Amazon Mechanical Turk completed an online survey, which included an abstract of an article describing scientific research with authors’ names and academic institutions, and questions on perceived scientific merit, religiosity, spirituality, religion as Quest, and perceived conflict between religion and science. There was a significant difference in the perceived merit of the researchers, with the group believing the researchers were affiliated with a religious academic institution rating the research as lower in scientific merit than the group believing the researchers were affiliated with a nonreligious academic institution. The perceived level of conflict between religion and science was found to moderate the relationship, such that higher levels of perceived conflict between religion and science showed a greater difference in scientific merit between groups.

Numerous psychosocial and health factors contribute to perceived stress, social support, and problem-solving coping relating to overall well-being and life satisfaction in older adults. The effect of social support and problem-solving coping, however, remains largely untested as potential moderators. The present study was conducted to test whether social support and problem- solving coping would moderate the relation between perceived stress and life satisfaction in older adults. First, I anticipated that stress will be negatively related to life satisfaction at low levels of social support, while at high social support; stress will be unrelated to life satisfaction. Second, I expected that with low problem- solving coping, stress will be negatively related to life satisfaction, whereas, at levels of high problem- solving coping, stress will be unrelated to life satisfaction. Using an experimental survey and interview design with hierarchical regression analyses, I found no support that social support would moderate the relation between stress and life satisfaction. I found support that problem-solving coping moderated the relation between stress and life satisfaction. For individuals who engage in higher levels of problem- solving coping, higher levels of stress predicted lower levels of life satisfaction. On the other hand, at lower levels of problem-solving coping, more stress predicted lower levels of life satisfaction.

Menopause is a complex biopsychosocial phenomenon that is influenced by women’s attitudes, the attitudes of their partners, families, and friends, and societal norms. Previous research has shown that attitudes can be influenced by many factors, such as age and menopausal status. This study examined men’s and women’s attitudes toward several facets of menopause, including fertility, attractiveness, personal growth, emotional stability, and sexuality, using an Amazon Mechanical Turk sample of 194 females and 151 males. Results revealed that women and men differed significantly in their attitudes toward fertility, attractiveness, personal growth, and sexuality, with women having more positive attitudes on every dimension except sexuality. For females, age was a significant positive predictor for fertility, personal growth, and emotional stability; knowledge was a significant positive predictor for personal growth; and education was a significant positive predictor for emotional stability. For males, age was a significant positive predictor for fertility, and knowledge was a significant negative predictor for fertility. These results indicate that men typically have more negative attitudes toward menopause than do women, and that more potential predictors of menopause attitudes should be explored in future work to provide insight into the reasons for this difference.

Police officers in America interact with civilians on a daily basis as function of their job, and the way people perceive police officers can either help or hurt officers in performance of their duties. I conducted an experiment to test whether people perceive a police officer’s use of force differently depending on the officer’s race and gender. First, when an officer uses force, I propose competing hypotheses that a female officer will be viewed as less favorable than a male officer; however, because female aggression is less expected, I also predict that they will be viewed as more favorable than male officers. Second, when an officer uses force, I predict that a Black officer will be viewed as more aggressive than a White Officer. Lastly, I predict that perceptions of the officer (i.e., perceived aggression and emotional reactivity) would mediate the relationship between officer gender and attitudes towards the officer. Using an experimental survey design with a video of a police-civilian interaction, I found support that female officers were viewed more favorably than male officers when force was used. I found no support that Black officers would be viewed as more aggressive than White officers. Lastly, I found partial support that perceptions of the officer mediated the relationship between officer gender and attitudes towards the officer.

Stress is an arguably universal phenomenon that has maladaptive effects on individuals’ mental health (i.e., depression). Individuals traditionally deal with stress through various coping strategies that fall under three coping styles: emotion-oriented coping, avoidance/disengagement coping, and problem-oriented coping. Furthermore, numerous studies have focused on the stress-reducing properties of music, but the literature lacks an examination of the use and effectiveness of music as a coping strategy. The current thesis examined the moderating role of music as a coping strategy in the link between stress and depression. Based on existing research, the author predicted that for participants who endorsed music coping as emotion-oriented or avoidance /disengagement-oriented, there would be an exacerbation of the stress-depression link. However, for participants who endorsed music coping as problem-oriented, there would be an attenuation of the stress-depression link. In an online survey-based study of 207 students attending Arizona State University, the author found that emotion-oriented music coping and avoidance/disengagement music coping exacerbated the relationship between stress and depression. The author, however, did not find support for the prediction that higher endorsement of problem-oriented music coping would buffer the effect of stress on depression. These results suggest that music coping may parallel alternative coping strategies in some respects but not others. Overall, the study findings support the further examination of music as a coping strategy in order to replicate emotion-oriented coping as the primary use of music.

Research on the psychology of social power has shown how experiences of power tend to promote goal-oriented behavior and sexual perception in individuals. These experiences need not be generated through real-life power dynamics, but can be primed experimentally in the lab. A recent study has explored how power affects even lower level goal-oriented motor movement, showing how increased power facilitates the initiation of goal-oriented motor actions (Maner et al., 2010). However, this research did not explore how these goal-oriented motor movements promoted by power dynamically evolve over time, or can be influenced by sexual perceptual processes. Using an experimental paradigm known as computer mouse-tracking, we designed an experimental task to asses how participants’ – primed with either a High or Low sense of power – motor movements and sexual perceptual processes co-evolved and influenced one another during decision-making. We analyzed four distinct mouse-tracking variables, including traditional reaction time measures and novel measures indexing real-time decision-making processes. Several hypotheses are proposed and discussed. No significant findings emerged, however general trends showed promising signs for future iterations of the study. The study limitations and proposed future directions for studying these phenomena are discussed.

The previous research literature was reviewed on how perpetrator's group membership and individuals' racial identity impact intergroup attitude and behavior, as well as factors contribute to intergroup bias on individuals' empathy level. This study was designed to extend the existing research on intergroup relations by exploring the effect of perpetrator's ingroup/outgroup membership and the strength of racial identity on people's empathy toward the outgroup victims. A web-based survey was disseminated and administrated at a southwest university. One hundred and six Caucasian American college students who completed the survey and met the criterion of eighteen years old or older were involved in this study. Participants were randomly assigned to read one of two target stories and one distracter story, and reported their empathy level toward each story. And then the participants' strength of racial identity was measured.

Controlling for demographic variables, regression analyses revealed that, as expected, the interaction of the perpetrator's group membership and individuals' racial identity significantly predicted the level of empathy toward the outgroup victim. When the perpetrator was an ingroup member, people who highly identified with their group exhibited less empathy for the outgroup victim. However, perpetrator's membership and the strength of racial identity failed to predict individuals' outgroup empathy separately.
