Depression is associated with increased cortisol secretion and occurs more often in women than in men. Thus, it has been hypothesized that differences in cortisol secretion might, in part, be responsible for the greater risk of developing depression in women. However, only few studies have examined sex differences in baseline cortisol secretion in depressed patients and healthy controls. We examined sex effects on cortisol secretion in 52 medication-free patients with major depression (37 women, 15 men, mean ± SD age 35 ± 11 years, Hamilton Depression Scale mean score 27 ± 5) and 50 healthy age- and sex-matched control subjects. Salivary cortisol concentrations were measured at 8:00, 12:00, 16:00, and 22:00 h. Repeated measures analysis of covariance revealed a group × sex interaction (p = 0.05). Post hoc tests revealed higher cortisol concentrations in depressed compared to healthy men [F(1;29) = 7.5, p = 0.01]. No differences were found between depressed and non-depressed women. Our results do not support the hypothesis that differences in cortisol secretion between depressed and non-depressed subjects are more pronounced in women than in men. Study characteristics and methods as well as sex-specific confounding variables such as menstrual cycle, menopause and the use of oral contraceptives may account for inconclusive results across studies. 相似文献

In this article I am concerned with analogical reasoning in ethics. There is no doubt that the use of analogy can be a powerful tool in our ethical reasoning. The importance of this mode of reasoning is therefore commonly accepted, but there is considerable debate concerning how its structure should be understood and how it should be assessed, both logically and epistemically. In this paper, I first explain the basic structure of arguments from analogy in ethics. I then discuss the diversity of analogical arguments that can be found in ethics. I analyse their structure, assess them from a logical viewpoint, and show how they can be epistemically challenged and defended. The result of this investigation is that, contrary to a commonly held view, analogical reasoning can be a logically valid type of ethical reasoning that can provide reasons for action that are not worse than the reasons provided by any other kind of practical reasoning. 相似文献

This study aimed to evaluate four main predictions of the Interpersonal Psychological Theory of Suicide (IPTS): the importance of perceived burdensomeness (PB), thwarted belongingness (TB), hopelessness (H), and capability for suicide (CS) for (passive/active) suicide ideation, suicide intent and suicide attempts. N = 308 psychiatric inpatients admitted due to severe suicidality (53.6% female: n = 165; age: M = 36.82, SD = 14.30, range: 18–81) completed self-report measures of TB, PB, H, CS and suicide ideation as well as interviews on suicide intent and suicide attempts. TB and PB were associated with (passive/active) suicidal ideation, whereas the three-way interaction PB, TB, and H was not associated with active suicide ideation. Fearlessness about death in conjunction with active suicidal ideation was not associated with suicide intent and the interaction of PB, TB, and CS was neither predictive of recent suicide attempt status nor lifetime number of suicide attempts. Given the cross-sectional nature of the data, conclusions on causality should be handled carefully. The results challenge the theoretical validity of the IPTS and its clinical utility—at least within the methodological limitations of the current study. Yet, findings underscore the importance of PB in understanding suicidality. 相似文献

In order to expand on previous research, this cross-sectional study investigated the relationship between Emotional Intelligence (EI) and cognitive abilities in healthy adults with a special focus on potential sex differences. EI was assessed by means of the Mayer-Salovey-Caruso-Emotional-Intelligence Test (MSCEIT), whereas cognitive abilities were investigated using the Brief Assessment of Cognition in Schizophrenia (BACS), which measures key aspects of cognitive functioning, i.e. verbal memory, working memory, motor speed, verbal fluency, attention and processing speed, and reasoning and problem solving. 137 subjects (65% female) with a mean age of 38.7 ± 11.8 years were included into the study. While males and females were comparable with regard to EI, men achieved significantly higher BACS composite scores and outperformed women in the BACS subscales motor speed, attention and processing speed, and reasoning and problem solving. Verbal fluency significantly predicted EI, whereas the MSCEIT subscale understanding emotions significantly predicted the BACS composite score. Our findings support previous research and emphasize the relevance of considering cognitive abilities when assessing ability EI in healthy individuals. 相似文献

Traditional explanations of anxiety reduction through behavioral interventions such as extinction, habituation, reciprocal inhibition, and counterconditioning do not adequately account for all instances and aspects of anxiety reduction and clinical methods employed in contemporary behavior therapy. This article examines the role of an additional process — the alterations of perceptions of control — believed to be operative in anxiety reduction. We discuss three targets for establishing control in behavioral treatments of anxiety: (1) control over one's physiological responding while in an anxiety-producing situation, (2) control over the anxiety-producing stimulus or situation itself, and (3) control over the conduct of exposure. These three types of control perceptions are differentially important for different types of anxiety disorders. Implications for the conduct of behavioral treatments and possibilities for increasing client perceptions of control in anxiety treatment programs are outlined. We also recommend that client perceptions of control should be systematically assessed in order to relate them to treatment successes and failures. 相似文献

A pervasive hypothesis in the timing literature is that temporal processing in the milliseconds and seconds range engages the basal ganglia and is modulated by dopamine. This hypothesis was investigated by testing 12 patients with Parkinson's disease (PD), both 'on' and 'off' dopaminergic medication, and 20 healthy controls on three timing tasks. In a seconds range (30-120 s) time production task, patients tested 'on' medication showed a significantly different accuracy profile compared to controls and when tested 'off' medication. However, no group or on vs off medication differences in accuracy were found on a time reproduction task and a warned reaction time task requiring temporal processing within the 250-2000 ms range. Variability was measured using the coefficient of variation, with the performance of the patient group on the time reproduction task violating the scalar property, suggesting atypical temporal processing mechanisms. The data suggest that the integrity of the basal ganglia is necessary for 'typical' time production in the seconds range as well as for time reproduction at shorter intervals. Exploratory factor analysis suggested that the time production task uses neural mechanisms distinct from those used in the other two timing tasks. The dissociation of the effects of dopaminergic medication and nature of task on performance in PD raises interesting questions about the pharmacological mediation and task-specificity of deficits in temporal processing. 相似文献

There is a long-standing debate whether propositions, sentences, statements or utterances provide an answer to the question
of what objects logical formulas stand for. Based on the traditional understanding of logic as a science of valid arguments,
this question is firstly framed more exactly, making explicit that it calls not only for identifying some class of objects,
but also for explaining their relationship to ordinary language utterances. It is then argued that there are strong arguments
against the proposals commonly put forward in the debate. The core of the problem is that an informative account of the objects
formulas stand for presupposes a theory of formalization; that is, a theory that explains what formulas may adequately substitute
for an inference in proofs of validity. Although such theories are still subject to research, some consequences can be drawn
from an analysis of the reasons why the common accounts featuring sentences, propositions or utterances fail. Theories of
formalization cannot refer to utterances qua expressions of propositions; instead they may refer to sentences and rely on
additional information about linguistic structure and pragmatic context. 相似文献
