Relationship between loudness tolerance and the acceptance of background noise for young adults with normal hearing

This study investigated the relationship between listener loudness tolerance and listener acceptable noise level (ANL). Twenty-five normal hearing adults completed loudness tolerance and acceptable noise level measures. Loudness tolerance was measured using a scaling technique. The acceptable noise levels were calculated from a procedure designed to quantify a listener's willingness to accept background noise while listening to speech. Pearson correlation confirmed that loudness tolerance and acceptable noise levels are not related.     

The physical postures of yoga practices may protect against depressive symptoms,even as life stressors increase: a moderation analysis

Yoga contains sub-components related to its physical postures (asana), breathing methods (pranayama), and meditation (dhyana). To test the hypothesis that specific yoga practices are associated with reduced psychological distress, 186 adults completed questionnaires assessing life stressors, symptom severity, and experience with each of these aspects of yoga. Each yoga sub-component was found to be negatively correlated with psychological distress indices. However, differing patterns of relationship to psychological distress symptoms were found for each yoga sub-component. Experience with asana was negatively correlated with global psychological distress (r = ?.21, p < .01), and symptoms of anxiety (r = ?.18, p = .01) and depression (r = ?.17, p = .02). These relationships remained statistically significant after accounting for variance attributable to Social Readjustment Rating Scale scores (GSI: r = ?.19, p = .01; BSI Anxiety: r = ?.16, p = .04; BSI Depression: r = ?.14, p = .05). By contrast, the correlations between other yoga sub-components and symptom subscales became non-significant after accounting for exposure to life stressors. Moreover, stressful life events moderated the predictive relationship between amount of asana experience and depressive symptoms. Asana was not related to depressive symptoms at low levels of life stressors, but became associated at mean (t[182] = ?2.73, p < .01) and high levels (t[182] = ?3.56, p < .001). Findings suggest asana may possess depressive symptom reduction benefits, particularly as life stressors increase. Additional research is needed to differentiate whether asana has an effect on psychological distress, and to better understand potential psychophysiological mechanisms of action.     

Challenges using motivational interviewing as an adjunct to exposure therapy for obsessive-compulsive disorder

Exposure and response prevention (EX/RP) is an efficacious treatment for obsessive-compulsive disorder (OCD). However, patients often do not adhere fully to EX/RP procedures. Motivational interviewing (MI) has been shown to improve treatment adherence in other disorders. This pilot study used a randomized controlled design to examine whether MI can be successfully added to EX/RP and whether this intervention (EX/RP + MI) could improve patient adherence to between-session EX/RP procedures relative to EX/RP alone. Thirty adults with OCD were randomized to 18 sessions of EX/RP or EX/RP + MI. Therapists rated patient adherence at each exposure session. Independent evaluators assessed change in OCD and depressive symptoms, and patients completed self-report measures of readiness for change and quality of life. The two treatment conditions differed in degree of congruence with MI but not in conduct of EX/RP procedures. Both groups experienced clinically significant improvement in OCD symptoms, without significant group differences in patient adherence. There are several possible reasons why EX/RP + MI had no effect on patient adherence compared to standard EX/RP, each of which has important implications for the design of future MI studies in OCD. We recommend that MI be further evaluated in OCD by exploring alternative modes of delivery and by focusing on patients less ready for change than the current sample.     

The functions of nonsuicidal self-injury: support for cognitive-affective regulation and opponent processes from a novel psychophysiological paradigm

Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.     

Sense of Humor and Its Relationship to Personality,Scholastic Aptitude,Emotional Maturity,Height, and Weight

Two experiments were performed having in common the use of sucrose concentration and volume as amount of reinforcement variables, and in situations permitting contrast between concentrations. The following conclusions are reached:

1. It is important to distinguish between the case in which separate subjects are exposed to different concentrations or volumes, and the case in which the same subjects receive different concentrations and volumes.

2. A distinction must be drawn between reinforcement contingencies in which force of response is or is not systematically related to concentration received. In nonforce contingent situations, emitted force is inversely related to concentration, when the same subjects are exposed to the different concentrations. In contingent situations, the relationship tends to be direct.

3. Rate and force of response vary inversely with nonforce contingent volume of sucrose reinforcement, when the same subjects are exposed to the different volumes.

4. Regardless of concentration and volume used, and presumably because of within-session satiation effects, there is a general tendency for rate to decline during nonforce contingent sessions.     

A theory of the normative force of pleas

A familiar feature of our moral responsibility practices are pleas: considerations, such as “That was an accident”, or “I didn’t know what else to do”, that attempt to get agents accused of wrongdoing off the hook. But why do these pleas have the normative force they do in fact have? Why does physical constraint excuse one from responsibility, while forgetfulness or laziness does not? I begin by laying out R. Jay Wallace’s (Responsibility and the moral sentiments, 1994) theory of the normative force of excuses and exemptions. For each category of plea, Wallace offers a single governing moral principle that explains their normative force. The principle he identifies as governing excuses is the Principle of No Blameworthiness without Fault: an agent is blameworthy only if he has done something wrong. The principle he identifies as governing exemptions is the Principle of Reasonableness: an agent is morally accountable only if he is normatively competent. I argue that Wallace’s theory of exemptions is sound, but that his account of the normative force of excuses is problematic, in that it fails to explain the full range of excuses we offer in our practices, especially the excuses of addiction and extreme stress. I then develop a novel account of the normative force of excuses, which employs what I call the “Principle of Reasonable Opportunity,” that can explain the full range of excuses we offer and that is deeply unified with Wallace’s theory of the normative force of exemptions. An important implication of the theory I develop is that moral responsibility requires free will.     

The Spontaneous Generation of the Human in the “Heng Xian”

This essay argues that the “Heng Xian” bridges between two distinct discourses that were both prevalent in the late fourth century. One discourse focused on the origination of the natural world through a spontaneous process of differentiation, a position familiar from the Daodejing and “Tai yi sheng shui.” The other focused on the specific ways in which different kinds of things live, a position known primarily from Ru discussions centering on the concept of xing 性, the nature or spontaneous reactions of a particular kind of thing. The “Heng Xian” attempts to account for the specificity of human life—including language and social organization—while remaining within a naturalistic view grounded in spontaneity. The essay concludes by reflecting on what the “Heng Xian” tells us about the status of human institutions.
