The Effect of a Brief Mindfulness Training on Distress Tolerance and Stress Reactivity

Poor distress tolerance (DT) is considered an underlying facet of anxiety, depression, and a number of other psychological disorders. Mindfulness may help to increase DT by fostering an attitude of acceptance or nonjudgment toward distressing experiences. Accordingly, the present study examined the effects of a brief mindfulness training on tolerance of different types of distress, and tested whether trait mindfulness moderates the effect of such training. Undergraduates (n = 107) naïve to mindfulness completed a measure of trait mindfulness and underwent a series of stress tasks (cold pressor, hyperventilation challenge, neutralization task) before and after completing a 15-minute mindfulness training or a no-instruction control in which participants listened to relaxing music. Participants in the mindfulness condition demonstrated greater task persistence on the hyperventilation task compared to the control group, as well as a decreased urge to neutralize the effects of writing an upsetting sentence. No effect on distress ratings during the tasks were found. Overall trait mindfulness did not significantly moderate task persistence, but those with lower scores on the act with awareness facet of mindfulness demonstrated greater relative benefit of mindfulness training on the hyperventilation challenge. Mediation analyses revealed significant indirect effects of mindfulness training on cold pressor task persistence and urges to neutralize through the use of the nonjudge and nonreact facets of mindfulness. These results suggest that a brief mindfulness training can increase DT without affecting the subjective experience of distress.     

Helping to reduce fights before flights: How environmental stressors in organizations shape customer emotions and customer–employee interactions

Previous examinations of environmental stressors in organizations have mostly emphasized their dysfunctional effects on individuals’ emotions and behaviors. Extending this work by drawing from the social functional perspective on emotion, we propose that customers’ negative emotional responses to environmental stressors in organizations can exert both dysfunctional and functional effects on customer–employee interactions. Specifically, we theorize that situational and physiological forms of environmental stressors can be dysfunctional by incurring customer anger, precipitating customer aggression, and diminishing employee helpfulness. We further theorize that situational relative to physiological stressors can exert functional effects in inducing customer fear that elicits empathy and helpfulness from employees. We test our model via an archival, observational, and critical incident yoked experimental study set in the airport context. This research contributes to stress theory and its organizational application by integrating theory from the social functional approach to emotion with appraisal-based theories of stress in organizations.     

Against epistemic partiality in friendship: value-reflecting reasons

Philosophical Studies - It has been alleged that the demands of friendship conflict with the norms of epistemology—in particular, that there are cases in which the moral demands of friendship...     

Accounting for the shared environment in cognitive abilities and academic achievement with measured socioecological contexts

Behavioral and molecular genetic research has established that child cognitive ability and academic performance are substantially heritable, but genetic variation does not account for all of the stratification of cognitive and academic outcomes across families. Which specific contexts and experiences contribute to these shared environmental influences on cognitive ability and academic achievement? Using an ethnically and socioeconomically diverse sample of N = 1728 twins ages 7–20 from the Texas Twin Project, we identified specific measured family, school, and neighborhood socioecological contexts that statistically accounted for latent shared environmental variance in cognitive abilities and academic skills. Composite measures of parent socioeconomic status (SES), school demographic composition, and neighborhood SES accounted for moderate proportions of variation in IQ and achievement. Total variance explained by the multilevel contexts ranged from 15% to 22%. The influence of family SES on IQ and achievement overlapped substantially with the influence of school and neighborhood predictors. Together with race, the measured socioecological contexts explained 100% of shared environmental influences on IQ and approximately 79% of shared environmental influences on both verbal comprehension and reading ability. In contrast, nontrivial proportions of shared environmental variation in math performance were left unexplained. We highlight the potential utility of constructing “polyenvironmental risk scores” in an effort to better predict developmental outcomes and to quantify children's and adolescents’ interrelated networks of experiences.

Temporary Safety Hazards

The Epistemic Objection says that certain theories of time (like the “growing block” and “moving spotlight”) imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in the details which avoids this problem, using epistemic safety. The new version has two interesting upshots. First, while Ross Cameron alleges that the Epistemic Objection applies to presentism as much as to theories like the growing block, the safety version does not overgeneralize this way. Second, the Epistemic Objection does generalize in a different, overlooked way. The safety objection is a serious problem for a widely held combination of views: “propositional temporalism” (objects of belief change truth‐value) together with “metaphysical eternalism” (the world does not objectively privilege any particular time).     

Agonistic character displacement in social cognition of advertisement signals

Interspecific aggression between sibling species may enhance discrimination of competitors when recognition errors are costly, but proximate mechanisms mediating increased discriminative ability are unclear. We studied behavioral and neural mechanisms underlying responses to conspecific and heterospecific vocalizations in Alston’s singing mouse (Scotinomys teguina), a species in which males sing to repel rivals. We performed playback experiments using males in allopatry and sympatry with a dominant heterospecific (Scotinomys xerampelinus) and examined song-evoked induction of egr-1 in the auditory system to examine how neural tuning modulates species-specific responses. Heterospecific songs elicited stronger neural responses in sympatry than in allopatry, despite eliciting less singing in sympatry. Our results refute the traditional neuroethological concept of a matched filter and instead suggest expansion of sensory sensitivity to mediate competitor recognition in sympatry.     

How does the extraversion personality trait influence false recall with the Deese–Roediger–McDermott (DRM) paradigm?

Relative to more introverted persons, extraverts have been found to exhibit better recall and recognition in a range of memory paradigms including demonstrating a superior semantic priming effect. The present study sought to establish whether this aspect of personality might be associated with the false memory paradigm developed by Deese, Roediger, and McDermott (the DRM paradigm). Lists containing semantically related words were presented to extraverts, ambiverts, and introverts. Compared to the other two groups, extraverts falsely recalled more critical lures (words that although semantically related were not in the original lists) and non-list words. The results are discussed in relation to the concept of spreading activation.     

Anti-Individualism, Content Preservation, and Discursive Justification

Most explorations of the epistemic implications of Semantic Anti‐Individualism (SAI) focus on issues of self‐knowledge (first‐person authority) and/or external‐world skepticism. Less explored has been SAI's implications for the epistemology of reasoning. In this paper I argue that SAI has some nontrivial implications on this score. I bring these out by reflecting on a problem first raised by Boghossian (1992) . Whereas Boghossian's main interest was in establishing the incompatibility of SAI and “the a priority of logical abilities” ( Boghossian 1992 : 22), I argue that Boghossian's argument is better interpreted as pointing to SAI's implications for the nature of discursive justification.
