This paper describes a long-term follow-up of patients with panic disorder who received cognitive behaviour therapy within a randomized controlled trial. Of 89 patients eligible for follow-up, 28 (31.5%) were reassessed 6-8 years after commencement of treatment in the trial. No differences were found between those who were followed up and those lost to follow-up on most baseline measures including measures of panic-related psychopathology, or depression. Outcomes at long-term follow-up were significantly better than baseline measures of panic, avoidance and depression. In this sub-sample the effect of cognitive behaviour therapy for panic disorder appears to maintain over the long-term. 相似文献

We conducted two word-by-word reading experiments to investigate the timing of implausibility detection for recipient and instrument prepositional phrases (PPs). These PPs differ in thematic role, relative frequency, and possibly in argument status. The results showed a difference in the timing of garden path effects such that the detection of implausible dative recipients (which are clearly arguments) was delayed relative to the detection of implausible instruments (which may not be arguments). They also demonstrated that commitments to syntactic structure were made at the preposition for both dative and instrument PPs. While these results refute delay models of parsing (e.g., Britt, 1994) and syntax-first accounts of PP-attachment (e.g., Frazier, 1978; Frazier & Clifton, 1996), they support constraint-based lexicalist models that enable verb bias and plausibility information to compete (Garnsey, Pearlmutter, Myers, & Lotocky, 1997). 相似文献

The U.S. Supreme Court's majorityopinion in Vacco v. Quill assumes thatthe principle of double effect explains thepermissibility of hastening death in thecontext of ordinary palliative care and inextraordinary cases in which painkilling drugshave failed to relieve especially intractablesuffering and terminal sedation has beenadopted as a last resort. The traditionaldoctrine of double effect, understood asproviding a prohibition on instrumental harmingas opposed to incidental harming or harming asa side effect, must be distinguished from otherways in which the claim that a result is notintended might be offered as part of ajustification for it. Although double effectmight appropriately be invoked as a constrainton ordinary palliative care, it is not clearthat it can be coherently extended to justifysuch practices as terminal sedation. A betterapproach would reconsider double effect'straditional prohibition on hastening death as ameans to relieve suffering in the context ofacute palliative care. 相似文献

In recent years, cognitive neuroscientists have began to explore the process of how sensory information gains access to awareness. To further probe this process, event-related functional magnetic resonance imaging (fMRI) was used while testing subjects with a paradigm known as the "attentional blink." In this paradigm, visually presented information sporadically fails to reach awareness. It was found that the magnitude and time course of activation within the anterior cingulate (BA 32), medial prefrontal cortex (BA 9), and frontopolar cortex (BA 10) predicted whether or not information was consciously perceived during the critical period for the attentional blink. These results are discussed in light of a neural framework for conscious processing. 相似文献

Previous researchers have proposed that there are two types of symmetry detection: one based on crude preattentive symmetry
judgments and another based on detailed scrutiny of individual parts (Barlow & Reeves, 1979; S. E. Palmer & Hemenway, 1978;
Royer, 1981). Four experiments were conducted to examine capacity limits in different symmetry judgments. Observers were required
to discriminate between random patterns and approximate symmetry (Experiments 1 and 3) or between perfect and approximate
symmetry (Experiments 2 and 4). The patterns were divided into two sets of dots, presented either simultaneously or successively.
A comparison of accuracy under these two presentation conditions suggested that symmetry detection involves an analysis that
is spatially parallel but coarse, regardless of either task difficulty or task type (detecting symmetry vs. detecting asymmetry). 相似文献

Religiousness and depression: evidence for a main effect and the moderating influence of stressful life events 总被引:10,自引:0,他引:10
The association between religiousness and depressive symptoms was examined with meta-analytic methods across 147 independent investigations (N = 98,975). Across all studies, the correlation between religiousness and depressive symptoms was -.096, indicating that greater religiousness is mildly associated with fewer symptoms. The results were not moderated by gender, age, or ethnicity, but the religiousness-depression association was stronger in studies involving people who were undergoing stress due to recent life events. The results were also moderated by the type of measure of religiousness used in the study, with extrinsic religious orientation and negative religious coping (e.g., avoiding difficulties through religious activities, blaming God for difficulties) associated with higher levels of depressive symptoms, the opposite direction of the overall findings. 相似文献

This study examined demographic characteristics, social competence, and behavior problems in clinic-referred children with gender identity problems in Toronto, Canada (N = 358), and Utrecht, The Netherlands (N = 130). The Toronto sample was, on average, about a year younger than the Utrecht sample at referral, had a higher percentage of boys, had a higher mean IQ, and was less likely to be living with both parents. On the Child Behavior Checklist (CBCL), both groups showed, on average, clinical range scores in both social competence and behavior problems. A CBCL-derived measure of poor peer relations showed that boys in both clinics had worse ratings than did the girls. A multiple regression analysis showed that poor peer relations were the strongest predictor of behavior problems in both samples. This study—the first cross-national, cross-clinic comparative analysis of children with gender identity disorder—found far more similarities than differences in both social competence and behavior problems. The most salient demographic difference was age at referral. Cross-national differences in factors that might influence referral patterns are discussed. 相似文献

The present paper examines the role of cognitive-behavioral therapy (CBT) in the treatment of social anxiety disorder (SAD). A cognitive-behavioral model of SAD is first presented. Different modalities of CBT for SAD are then described, including exposure, cognitive restructuring, relaxation training, and social skills training, and evidence supporting their efficacy is reviewed. The comparative and combined impact of CBT and pharmacotherapeutic interventions is also explored. CBT appears to be an efficacious treatment for SAD. However, the overall efficacy CBT may be increased by closer examination of the active ingredients of treatment. Such analyses may also enable more successful integration of the different CBT techniques and of CBT and pharmacotherapy in the treatment of SAD. 相似文献
