Jurors' Use of Instructions on Negligence1

At the end of a trial, the judge gives jurors a set of instructions that explain the laws that are applicable to the case and that direct jurors to reach a verdict in accordance with those laws. Little is known about how well jurors understand instructions in civil cases. We assess the extent to which jurors understand judicial instructions in negligence cases. We address 3 issues: (a) To what extent do they understand these instructions? (b) To what extent is their comprehension enhanced by access to a written copy of the instructions? and (c) What effect does deliberation have on jurors' comprehension levels? Overall comprehension was approximately 64% and access to written instructions did not enhance comprehension, but the opportunity to deliberate did.     

HPV High Risk and Protective Behaviors: The Effects of Religious Affiliation

The majority of Americans identify themselves as belonging to some religious group. There is a mixed body of literature on whether or not religious affiliation has an influence on engaging in risky behaviors among young adults attending college. This study examined associations between religious affiliation, risky sexual practices, substance use, and family structure among a sample of predominantly white college females attending a southeastern university. Given the high risk of acquiring genital human papillomavirus infection as a result of high risk sexual practices, gaining a better understanding of how religious affiliation can be used to promote healthy sexual behaviors is warranted.     

Effects of neuroimaging evidence on mock juror decision making

During the penalty phase of capital trials, defendants may introduce mitigating evidence that argues for a punishment "less than death." In the past few years, a novel form of mitigating evidence-brain scans made possible by technological advances in neuroscience-has been proffered by defendants to support claims that brain abnormalities reduce their culpability. This exploratory study assessed the impact of neuroscience evidence on mock jurors' sentencing recommendations and impressions of a capital defendant. Using actual case facts, we manipulated diagnostic evidence presented by the defense (psychosis diagnosis; diagnosis and neuropsychological test results; or diagnosis, test results, and neuroimages) and future dangerousness evidence presented by the prosecution (low or high risk). Recommendations for death sentences were affected by the neuropsychological and neuroimaging evidence: defendants deemed at high risk for future dangerousness were less likely to be sentenced to death when jurors had this evidence than when they did not. Neuropsychological and neuroimaging evidence also had mitigating effects on impressions of the defendant. We describe study limitations and pose questions for further research.     

Aversive learning overcomes appetitive innate responding in honeybees

Despite their miniature brain, honeybees have emerged as a powerful model for the study of learning and memory. Yet, they also exhibit innate responses to biologically relevant social signals such as pheromones. Here, we asked whether the bees’ developed learning capabilities allow them to overcome hardwired appetitive responses. Can they learn that attractant pheromones, that are not normally associated with a noxious stimulation in nature, predict the punishment of an electric shock? Immobilized honeybees were trained to discriminate two odorants, one that was paired with a shock and another that had no consequences. We measured whether they learned to produce aversive sting extension responses to the punished but not the non-punished odorant. One odorant was a neutral odor without innate value while the other was either an attractive pheromone (geraniol or citral) or an attractive floral odorant (phenylacetaldehyde). In all cases, bees developed a conditioned aversive response to the punished odorant, be it pheromone or not, and efficiently retrieved this information 1 h later. No learning asymmetries between odors were found. Thus, associative aversive learning in bees is strong enough to override preprogrammed responding, thus reflecting an impressive behavioral flexibility.     

Doing as they would do: How the perceived ethical preferences of third-party beneficiaries impact ethical decision-making

Although unethical behavior often benefits third-parties not directly complicit in the misconduct, not all beneficiaries welcome these ill-gotten benefits. We investigate whether actors consider the ethical preferences of potential beneficiaries or rely solely on their own ethical predispositions when making decisions that affect others. Three studies demonstrate that the perceived ethical preferences of these beneficiaries can substantially influence the likelihood that actors behave unethically on their behalves. These studies show that actors consider the ethical preferences of beneficiaries only when their own ethical disposition is outcome-based.     

Self-efficacy and social support as predictors of smoking after a quit attempt

Abstract

The current study examined self-efficacy and social support as predictors of maintenance after an attempt to stop smoking. As in previous studies, self-efficacy at the end of treatment was a significant predictor of reported smoking during the follow-up period. At 3 months after treatment the prediction from self-efficacy was weaker than a prediction from the level of post-treatment smoking. However at 10 months self-efficacy was the strongest predictive variable assessed in the study. In contrast, social support for the quit attempt was not a significant predictor of maintenance at any stage. The results provided qualified support for the contention that self-efficacy can often be a more powerful predictor than previous performance attainments, especially under conditions of greater situational change.     

The Predictive Power of Combined Neuropsychological Measures for Attention-Deficit/Hyperactivity Disorder in Children

The present study explores the predictive power of seven neuropsychological assessment tools used in combination in classifying children with attention-deficit/hyperactivity disorder (ADHD). Twenty-one ADHD boys and 22 community control children participated. Group differences were significant on the continuous performance test only; however, battery analysis did increase overall predictive power, which was moderate. This study highlights the difficulty in identifying consistent mean differences on tests of frontal/executive functioning across studies, as well as the need to assess the predictive validity of these tests in classifying children with ADHD. The study suggests that these tests may provide greater predictive validity when used in combination. Inconsistencies in the literature are discussed, with consideration of research methodology, the heterogeneity of the ADHD population, and comorbid diagnoses.     

Fields of Merit,Harvests of Health: Some Notes on the Role of Medical Karma in the Popularization of Buddhism in Early Medieval China

One of the most significant philosophical doctrines of Buddhism, and an idea that has remained at the centre of its theory and practice in virtually all historical times and places, is karma. The motivations for being involved in the accumulation of karmic merit in early medieval China were diverse, but one frequently mentioned goal was the health of the physical body. This brief article examines several facets of the relationship between karma and well-being, providing a few examples of the wide range of sources on this subject and reflecting on its role in the popularization of Buddhism in China. I argue that medical metaphors were central to how the doctrine of karma was explained to diverse audiences, that the translation of these ideas emphasized connections with indigenous beliefs and social practices and that medical karma encouraged the self-regulation of behaviour and thoughts in conformity with Buddhist ideology.
