Using a sample of 196 undergraduate students, the present study investigated the psychometric properties of the Spiritual Fitness Assessment, a measure of spiritual fitness designed for use by health and fitness professionals. Examination of inter-item consistency produced satisfactory alpha coefficients for the total test and its three subscales. Correlations of the SFA with measures of spirituality and spiritual well-being provide support for convergent validity. Significant positive correlations with a measure of self-esteem suggest that the test has satisfactory criterion validity. Correlations with age, sex, and a measure of social desirability indicate that the SFA is significantly, though only moderately, affected by demographic variables and motivated response tendencies. Factor analysis of the SFA items indicate that the test is factorially complex and subscales may need to be refined to better measure their intended constructs. Overall, the results of the study suggest that the test may be useful for evaluations of spiritual fitness. Further research with samples drawn from different populations is needed on the test to better establish its reliability and validity.  相似文献

This paper studies an economy whose agents perceive their consumption possibilities subjectively, and whose preferences are defined on what they subjectively experience, rather than on those alternatives that are objectively present. The model of agents’ perceptions is based on intuitionistic logic. Roughly, this means that agents reason constructively: a solution to a problem exists only if there is a construction by which the problem can be solved. The theorems that can be proved determine how an agent perceives a set of alternatives. A dual model relates perceived alternatives to a shared language, which the agents use in trading. So perceptions relate objective alternatives to an agent’s subjective view of them, and reporting dually relates an agent’s subjective world to a shared language. It turns out that an appropriately modified notion of competitive equilibrium always exists. However, in contrast with standard results in economic theory, competitive equilibrium need not be efficient.  相似文献

This paper argues that some traditional fallacies should be considered as reasonable arguments when used as part of a properly conducted dialog. It is shown that argumentation schemes, formal dialog models, and profiles of dialog are useful tools for studying properties of defeasible reasoning and fallacies. It is explained how defeasible reasoning of the most common sort can deteriorate into fallacious argumentation in some instances. Conditions are formulated that can be used as normative tools to judge whether a given defeasible argument is fallacious or not. It is shown that three leading violations of proper dialog standards for defeasible reasoning necessary to see how fallacies work are: (a) improper failure to retract a commitment, (b) failure of openness to defeat, and (c) illicit reversal of burden of proof.  相似文献

From the perspective of terror management theory, awareness of death induces a need for validation of important values. Thus, for women who place a high value on their appearance (e.g., high self-objectifiers), mortality salience should increase positive reactions to objectifying experiences relative to women who do not highly value appearance. Two studies supported this hypothesis. Self-objectification moderated favorable reactions to objectifying stimuli (Study 1) and state self-esteem in response to an objectifying comment (Study 2) when women were primed with death. Together, the studies illustrate the complexity of reactions to objectification and, by highlighting conditions in which objectification serves a psychological function, help to explain the pervasiveness of the phenomena.  相似文献

Posttraumatic Stress Disorder (PTSD) and Major Depressive Disorder (MDD) are two highly comorbid and debilitating disorders experienced by more than half of intimate partner violence victims (IPV). Hypothalamic–pituitary–adrenal (HPA) abnormalities are common in both disorders, though the direction of abnormalities often differs. The present study examined the relationship between comorbid PTSD and MDD, and the (salivary) cortisol waking response in 104 recently abused IPV victims. Waking cortisol levels, area under the waking curve with respect to ground (AUCg), and AUC with respect to increase (AUCi) were examined to determine the relation of HPA dynamics to comorbidity for basal versus more dynamic measures. Prior to accounting for comorbidity, women with PTSD or MDD showed significantly greater AUCi than women without the respective disorder. Accounting for comorbidity, PTSD only did not differ from other groups, while MDD only and PTSD + MDD showed greater AUCi than women with neither disorder. Results were nonsignificant for waking cortisol levels or AUCg. Results suggest that MDD drives elevated waking cortisol response, but not basal cortisol activity in recently abused IPV victims. Results demonstrate the importance of examining comorbid diagnoses and HPA activity from a dynamic perspective. Therapeutic implications are discussed.  相似文献

Although research on language production has developed detailed maps of the brain basis of single word production in both time and space, little is known about the spatiotemporal dynamics of the processes that combine individual words into larger representations during production. Studying composition in production is challenging due to difficulties both in controlling produced utterances and in measuring the associated brain responses. Here, we circumvent both problems using a minimal composition paradigm combined with the high temporal resolution of magnetoencephalography (MEG). With MEG, we measured the planning stages of simple adjective–noun phrases (‘red tree’), matched list controls (‘red, blue’), and individual nouns (‘tree’) and adjectives (‘red’), with results indicating combinatorial processing in the ventro-medial prefrontal cortex (vmPFC) and left anterior temporal lobe (LATL), two regions previously implicated for the comprehension of similar phrases. These effects began relatively quickly (∼180 ms) after the presentation of a production prompt, suggesting that combination commences with initial lexical access. Further, while in comprehension, vmPFC effects have followed LATL effects, in this production paradigm vmPFC effects occurred mostly in parallel with LATL effects, suggesting that a late process in comprehension is an early process in production. Thus, our results provide a novel neural bridge between psycholinguistic models of comprehension and production that posit functionally similar combinatorial mechanisms operating in reversed order.  相似文献

Anticipations of future sensory events have the potential of priming motor actions that would typically cause these events. Such effect anticipations are generally assumed to rely on previous physical experiences of the contingency of own actions and their ensuing effects. Here we propose that merely imagined action effects may influence behaviour similarly as physically experienced action effects do. Three experiments in the response–effect compatibility paradigm show that the mere knowledge of action–effect contingencies is indeed sufficient to incorporate these effects into action control even if the effects are never experienced as causally linked to own actions. The experiments further highlight constraints for this mechanism which seems to be rather effortful and to depend on explicit intentions.  相似文献

This pilot study compares an emerging evidence-based treatment, holographic reprocessing (HR) to prolonged exposure (PE) versus a person-centered (PC) control group to treat symptoms of distress in female Veterans with sexual trauma. In contrast to PE, HR does not include exposure to a target event of trauma. Instead, HR focuses on healing the internal working model or type of attachment style that may form as a result of interpersonal trauma or maltreatment. The model reveals how people perceive themselves and others. These perceptions set in motion emotional, cognitive, and behavioral tendencies wherein people unconsciously replicate similar types of relationships that reinforce their worldview. Fifty-one female Veterans with sexual trauma were randomly assigned to one of three treatments and completed pre- and post-treatment measures of psychiatric symptoms (anxiety, depression, and PTSD) and post-traumatic cognitions. ANOVAs found significant decreases on all variables. Post-hoc comparisons revealed that HR and PE treatments demonstrated significantly greater decreases in symptoms compared to the PC control group. Chi square analyses revealed that HR produced a significantly lower dropout rate 1 (6 %) compared to PE 7 (41 %) and PC 6 (35 %). These initial results are promising and further investigation of HR is warranted.  相似文献
