Differential effects of mindful breathing, progressive muscle relaxation, and loving-kindness meditation on decentering and negative reactions to repetitive thoughts

Decentering has been proposed as a potential mechanism of mindfulness-based interventions but has received limited empirical examination to date in experimental studies comparing mindfulness meditation to active comparison conditions. In the present study, we compared the immediate effects of mindful breathing (MB) to two alternative stress-management techniques: progressive muscle relaxation (PMR) and loving-kindness meditation (LKM) to test whether decentering is unique to mindfulness meditation or common across approaches. Novice meditators (190 female undergraduates) were randomly assigned to complete one of three 15-min stress-management exercises (MB, PMR, or LKM) presented by audio recording. Immediately after the exercise, participants completed measures of decentering, frequency of repetitive thoughts during the exercise, and degree of negative reaction to thoughts. As predicted, participants in the MB condition reported greater decentering relative to the other two conditions. The association between frequency of repetitive thought and negative reactions to thoughts was relatively weaker in the MB condition than in the PMR and LKM conditions, in which these two variables were strongly and positively correlated. Consistent with the construct of decentering, the relative independence between these two variables in the MB condition suggests that mindful breathing may help to reduce reactivity to repetitive thoughts. Taken together, results help to provide further evidence of decentering as a potential mechanism that distinguishes mindfulness practice from other credible stress-management approaches.     

Learning to use words: Event-related potentials index single-shot contextual word learning

Humans have the remarkable capacity to learn words from a single instance. The goal of this study was to examine the impact of initial learning context on the understanding of novel word usage using event-related brain potentials. Participants saw known and unknown words in strongly or weakly constraining sentence contexts. After each sentence context, word usage knowledge was assessed via plausibility ratings of these words as the objects of transitive verbs. Plausibility effects were observed in the N400 component to the verb only when the upcoming novel word object had initially appeared in a strongly constraining context. These results demonstrate that rapid word learning is modulated by contextual constraint and reveal a rapid mental process that is sensitive to novel word usage.     

Race differences in psychopathology and disparities in treatment seeking: Community and jail-based treatment seeking patterns

Whites in community samples utilize mental health services at a much higher rate than African Americans (Kessler, et al., 2005). Is this also the case among those in jails? In this study of jail inmates (229 African American, 185 White) there were no race difference in the overall need for mental health treatment (63% of participants had significant symptoms on the Personality Assessment Inventory) but race differences in the level and types of symptoms were evident. Additionally, while Whites were more likely to report pre-incarceration treatment there were no differences in treatment seeking or access to mental health programs while in jail, implying that if barriers to treatment in the community were removed (cost/insurance, location/transportation, time) racial disparities in treatment utilization may be reduced.     

Organizational Citizenship Behaviors as a Function of Empathy,Consideration of Future Consequences,and Employee Time Horizon: An Initial Exploration Using an In‐Basket Simulation of OCBs1

We hypothesized that organizational citizenship behaviors (OCBs) represent a social dilemma. Two studies supported this hypothesis. In Study 1, participants rated OCBs as costly to an employee in the short run, and beneficial to an organization in the long run. In Study 2, likelihood of engaging in OCBs was higher among those high in empathy and concern with future consequences; and less likely among those instructed to imagine they would be leaving the company in 3 months for another job. Empathy showed a stronger relationship with OCBs when respondents imagined they would soon leave an organization and that individuals high in concern with future consequences were less likely to engage in OCBs when faced with a short‐term time horizon.     

Computerized adaptive testing under nonparametric IRT models

Nonparametric item response models have been developed as alternatives to the relatively inflexible parametric item response models. An open question is whether it is possible and practical to administer computerized adaptive testing with nonparametric models. This paper explores the possibility of computerized adaptive testing when using nonparametric item response models. A central issue is that the derivatives of item characteristic Curves may not be estimated well, which eliminates the availability of the standard maximum Fisher information criterion. As alternatives, procedures based on Shannon entropy and Kullback–Leibler information are proposed. For a long test, these procedures, which do not require the derivatives of the item characteristic eurves, become equivalent to the maximum Fisher information criterion. A simulation study is conducted to study the behavior of these two procedures, compared with random item selection. The study shows that the procedures based on Shannon entropy and Kullback–Leibler information perform similarly in terms of root mean square error, and perform much better than random item selection. The study also shows that item exposure rates need to be addressed for these methods to be practical. The authors would like to thank Hua Chang for his help in conducting this research.     

Multi‐agency collaboration,multiple levels of meaning: social constructionism and the CMM model as tools to further our understanding

This study explores the discourse emerging when professionals from a child and adolescent mental health service meet with professionals from other agencies to discuss cases. The study is timely, given the current political contextual forces pushing agencies to work together which run alongside an expanding literature acknowledging the obstacles to achieving this. A thematic analysis identified nine themes, defined according to their discourse type, including single agency discourse, case complexity discourse and multi‐agency discourse. In this paper, the usefulness of the coordinated management of meaning model (CMM) is examined as an additional tool which may be used in data analysis to help understand the discourse within multi‐agency meetings. The two approaches to data analysis are complementary to each other, with both allowing for different layers of context and complexity to emerge from the data.     

Does Skeptical Theism Lead to Moral Skepticism?

The evidential argument from evil seeks to show that suffering is strong evidence against theism. The core idea of the evidential argument is that we know of innocent beings suffering for no apparent good reason. Perhaps the most common criticism of the evidential argument comes from the camp of skeptical theism, whose lot includes William Alston, Alvin Plantinga, and Stephen Wykstra. According to skeptical theism the limits of human knowledge concerning the realm of goods, evils, and the connections between values, undermines the judgment that what appears as pointless evil really is pointless. For all we know the suffering of an innocent being, though appearing pointless, in fact leads to a greater good. In this paper I argue that no one who accepts the doctrines of skeptical theism has a principled way of avoiding moral skepticism.     

The effects of speech production and speech comprehension on simulated driving performance

We performed two experiments comparing the effects of speech production and speech comprehension on simulated driving performance. In both experiments, participants completed a speech task and a simulated driving task under single‐ and dual‐task conditions, with language materials matched for linguistic complexity. In Experiment 1, concurrent production and comprehension resulted in more variable velocity compared to driving alone. Experiment 2 replicated these effects in a more difficult simulated driving environment, with participants showing larger and more variable headway times when speaking or listening while driving than when just driving. In both experiments, concurrent production yielded better control of lane position relative to single‐task performance; concurrent comprehension had little impact on control of lane position. On all other measures, production and comprehension had very similar effects on driving. The results show, in line with previous work, that there are detrimental consequences for driving of concurrent language use. Our findings imply that these detrimental consequences may be roughly the same whether drivers are producing speech or comprehending it. Copyright © 2005 John Wiley & Sons, Ltd.     

The Secret Lives of Liberals and Conservatives: Personality Profiles,Interaction Styles,and the Things They Leave Behind

Although skeptics continue to doubt that most people are “ideological,” evidence suggests that meaningful left‐right differences do exist and that they may be rooted in basic personality dispositions, that is, relatively stable individual differences in psychological needs, motives, and orientations toward the world. Seventy‐five years of theory and research on personality and political orientation has produced a long list of dispositions, traits, and behaviors. Applying a theory of ideology as motivated social cognition and a “Big Five” framework, we find that two traits, Openness to New Experiences and Conscientiousness, parsimoniously capture many of the ways in which individual differences underlying political orientation have been conceptualized. In three studies we investigate the relationship between personality and political orientation using multiple domains and measurement techniques, including: self‐reported personality assessment; nonverbal behavior in the context of social interaction; and personal possessions and the characteristics of living and working spaces. We obtained consistent and converging evidence that personality differences between liberals and conservatives are robust, replicable, and behaviorally significant, especially with respect to social (vs. economic) dimensions of ideology. In general, liberals are more open‐minded, creative, curious, and novelty seeking, whereas conservatives are more orderly, conventional, and better organized.
