Physiological and symptom responses to hyperventilation: A comparison of frequent and infrequent panickers

Ten subjects with panic disorder and ten subjects with infrequent panic attacks were assessed during 2 min of voluntary hyperventilation using four measures of physiological arousal (heart rate, upper trapezious EMG, skin conductance, and digital skin temperature). Immediately following hyperventilation, subjects were asked to rate their degree of distress on 13 panic symptoms, derived from DSM-III criteria for panic disorder. Results indicated that frequent panickers had significant overall elevations in trapezious EMG, relative to infrequent panickers, and demonstrated a slight increase in muscle tension following hyperventilation. In contrast, infrequent panickers showed a trend toward greater vasodilation preceding and during hyperventilation, with subsequent vasoconstriction upon resumption of normal breathing. Increases in skin conductance and heart rate were noted for both samples during hyperventilation, as reported in prior research. Symptom distress ratings indicated that the infrequent panickers reported significantly greater distress from dizziness and trembling in response to overbreathing, contrary to prediction. Implications of these findings are discussed in light of current accounts of cognitive and physiological factors in the etiology of panic attacks and panic disorder.This research was supported by Biomedical Research Support Grant #507RR07147, National Institutes of Health.     

The coherence of memories for trauma: Evidence from posttraumatic stress disorder

Participants with posttraumatic stress disorder (PTSD) and participants with a trauma but without PTSD wrote narratives of their trauma and, for comparison, of the most-important and the happiest events that occurred within a year of their trauma. They then rated these three events on coherence. Based on participants’ self-ratings and on naïve-observer scorings of the participants’ narratives, memories of traumas were not more incoherent than the comparison memories in participants in general or in participants with PTSD. This study comprehensively assesses narrative coherence using a full two (PTSD or not) by two (traumatic event or not) design. The results are counter to most prevalent theoretical views of memory for trauma.     

Salutogenesis and autobiographical disclosure among Holocaust survivors

Forty-five Holocaust survivors and a comparison group of 21 Jews who had not experienced Nazi persecution completed questionnaires assessing salutogenic (health-enhancing) and pathogenic (illness-inducing) outcomes of Holocaust vs. other traumatic experiences. Salutogenesis and pathogenesis were negatively correlated. Holocaust survivors were consistently higher on the measure of salutogenesis; with marital history held constant, this difference was statistically significant. Neither group reported high incidences of posttraumatic stress symptoms, although survivors reported more. Talking about one's Holocaust experiences was related to more positive and fewer negative responses. Marital history and religious observance mediated some aspects of both positive and negative long-term consequences. The results indicate that the long-term consequences of even extreme trauma may include increased personal strength and growth.     

Maturity is coherent: Structural and content-specific coherence in adolescent moral identity

Identity narrative may involve considerable variations in structural and content-specific coherence. These variations are potentially relevant to the development of moral commitment in adolescence. The present study analyzed coherence in moral identity narratives for a matched comparison sample of urban adolescents. Thirty nominated adolescent moral exemplars and 30 everyday comparators were given interview prompts designed to tap identity narrative. Structural and content-specific coherence dimensions were assessed with a palette of computational techniques known as coh-metrix. Consistent with study hypotheses, exemplar adolescent moral identity narratives generally evinced greater structural and content-specific coherence than everyday comparators, particularly on causality and agentic intentionality dimensions. Findings suggest that moral identity coherence is a kind of expertise fixed in developmental processes and associated with real-world action.     

藏传佛教觉域派及其教法特点

觉域派是公元 1 1世纪产生于西藏的藏传佛教重要宗派之一 ,由藏族著名的女密宗大师玛久拉仲所创立。觉域派的教法 ,主要是以般若波罗蜜多为宗义 ,结合大手印觉法修持的一种法门 ,就是以菩提心或慈悲心来断灭自利心 ,以般若性空来断除我执。故觉域派的教法 ,又称般若波罗蜜多之觉域法或大手印觉法。     

Silent letters and phonological priming

Many written English words contain silent letters. Omitting them produces nonwords pronounced identically to the original words, for example, SALM for PSALM and COLUM for COLUMN. We report two naming and two lexical decision experiments in which targets of 4–11 letters followed primes exposed for 100 ms in mask-prime-mask-target sequences. Priming in SALM-psalm and COLUM-column pairs exceeded priming in orthographic control pairs such as ASTA-pasta and COUSI-cousin, pairs in which pronounced letters are omitted to form the primes. SALM and COLUM, however, were less effective primes than PSALM and COLUMN. Results were discussed in terms of the phonological coherence hypothesis, the role of orthographic codes in filtering phonologically activated representations, and graphemes as reading units.     

THEORETICAL,PRACTICAL, AND SOCIAL ISSUES IN BEHAVIORAL TREATMENTS OF OBESITY

Although showing superior maintenance, behavioral treatments of obesity typically produce small weight losses at a decelerating rate. Rather than reflecting poor compliance with treatment, these findings are consistent with known compensatory metabolic changes that operate to slow weight loss and promote regain. Other problems associated with dieting include failure of caloric regulation, hyper-responsivity to food palatability, and hunger, which is greatest under conditions of moderate restriction and unpredictability of access to food. The inevitability of treatment failure in many instances must be faced and efforts made to prevent further worsening of the obese patient's self-esteem. Prognosis and treatment planning may be aided by consideration of the historical difficulties of weight loss, the degree of hunger experienced on diets, which may reflect important physiological differences among individuals, and the use of food to optimize arousal level. Full involvement of the patient in setting goals and planning treatment is recommended.     

Scientia Iuris - An Unsolved Philosophical Problem

Legal dogmatics in Continental European law (scientia iuris, Rechtswissenschaft) consists of professional legal writings whose task is to systematize and interpret valid law. Legal dogmatics pursues knowledge of the existing law, yet in many cases it leads to a change of the law. Among general theories of legal dogmatics, one may mention the theories of negligence, intent, adequate causation and ownership. The theories produce principles and they also produce defeasible rules. By means of production of general and defeasible theories, legal dogmatics aims at obtaining a system of law that is both internally coherent and harmonized with its background in morality and (political) philosophy. Legal dogmatics is necessary in the context of constitutional constraints on the majority rule. Only if the courts act on the basis of Reason they can be a legitimate counterpart of the majority rule. And Reason cannot be exhausted by particular decision making. It also needs a more abstract deliberation, given by expert jurists. However, legal dogmatics has been a target of several kinds of criticism: empirical, morally-political, epistemological, logical, and ontological. The position taken in this article is to answer such criticism by mutually adjusting philosophy and the practices of the law.     

Troubles with Theoretical Virtues: Resisting Theoretical Utility Arguments in Metaphysics

In this paper we examine theoretical utility arguments in metaphysics. While philosophers claim a procedural continuity with science when using such arguments, we argue that examining famous instances from the history of science expose their fundamental flaws. We find that arguments from theoretical utility invoke considerations that are not truth conducive and that justifications for claims that a theory possesses theoretical virtues often assume the truth of the theory such virtues are supposed to support. We conclude that theoretical utility arguments provide no epistemic grounds for metaphysical inquiry.
