This study investigates the relationship between three types of disputes used in Rational Emotive Behavior Therapy (REBT), and the five personality domains of the Five Factor Model of Personality. A sample of 194 subjects was assessed for the use of three categories of REBT disputes using the Ellis Emotional Efficiency Inventory (EEEI), and for the Big Five personality dimensions using the NEO-Five Factor Inventory (NEO-FFI). Disputing against “awfulizing” was found to correlate inversely with Neuroticism. Disputing against “self-downing” was found to correlate positively with both Extraversion and Conscientiousness. Disputing against “low frustration tolerance” was found to correlate positively with Agreeableness and Openness. Implications for REBT practice and research are discussed.  相似文献

We sketch a broadening of the Gupta-Belnap notion of a circular or revision theoretic definition into that of a more generalized form incorporating ideas of Kleene’s generalized or higher type recursion. This thereby connects the philosophically motivated, and derived, notion of a circular definition with an older form of definition by recursion using functionals, that is functions of functions, as oracles. We note that Gupta and Belnap’s notion of ‘categorical in L’ can be formulated in at least one of these schemes.

Non-linear fractal analysis of cardiac interbeat time series was performed in corticotropin-releasing factor receptor subtype 2 (CRFR2) deficient mice. Heart rate dynamics in mice constitutes a self-similar, scale-invariant, random fractal process with persistent intrinsic long-range correlations and inverse power-law properties. We hypothesized that the sustained tachycardic response elicited by intraperitoneal (ip) injection of human/rat CRF (h/rCRF) is mediated by CRFR2. In wildtype control animals, heart rate was increased to about maximum levels (~ 750 bpm) while in CRFR2-deficient animals baseline values were retained (~ 580 bpm). The tachycardic response elicited by ip-application is mediated by CRFR2 and is interpreted to result from sympathetic stimulation. However, the functional integrity of CRFR2 would not present a prerequisite to maintaining the responsiveness and resiliency of cardiac control to external environmental perturbations experimentally induced by extrinsic ip-application of h/rCRF or under physiological conditions that may be associated with an increased peripheral release of CRF. Under stressful physiological conditions achieved by novelty exposure, CRFR2 is not involved in the cardiodynamic regulation to external short-term stress. While the hypothesis of involvement of CRFR2 in cardiac regulation upon pharmacological stimulation cannot be rejected, the present findings suggest that the mechanism of action is by sympathetic stimulation, but would not unambiguously allow to draw any conclusions as to the physiological role of CRFR2 in the control of cardiac dynamics.  相似文献

In less than 50 years, the rate of suicide among Sri Lankans has risen from a modest level to one of the highest in the world. This article describes the current pattern of suicides, including sex differences and similarities, and reviews some of the institutional practices, material conditions, and social norms that may figure in the increases. A study is reported, which asked how ordinary Sri Lankans account for suicidal behavior and what practices they recommend for assisting suicidal individuals. Gender inflected these accounts, with essentialist accounts associated with women's suicides and contextual accounts associated with men's suicides.  相似文献
