Selective attention has durable consequences for behavior and neural activation. Negative priming (NP) effects are assumed to reflect a critical inhibitory component of selective attention. The performance of adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) was assessed across two conceptually based NP tasks within a selective attention procedure. Comorbidity (non-comorbid ADHD vs. comorbid ADHD) and subtype (ADHD combined vs. ADHD inattentive) were considered key issues. Results found NP effects to differ as a function of comorbidity but not subtype. Findings are discussed in light of functional neuroimaging evidence for neuronal enhancement for unattended stimuli relative to attended stimuli that strongly complements an inhibitory-based explanation for NP. Implications for the ‘AD’ in ADHD and contemporary process models of the disorder are considered. 相似文献

In this article we suggest that independent vs. interdependent aspects of the self yield different manifestations of psychological reactance and that this is especially relevant in a cross-cultural context. In Studies 1, 2, and 4 we showed that people from collectivistic cultural backgrounds (individuals holding more interdependent attitudes and values) were less sensitive to a threat to their individual freedom than people from individualistic cultural backgrounds (individuals holding more independent attitudes and values), but more sensitive if their collective freedom was threatened. In Study 3 we activated independent vs. interdependent attitudes and values utilizing a cognitive priming method and yielded similar results as the other studies hinting at the important causal role of self-related aspects in understanding reactance in a cross-cultural context. 相似文献

ABSTRACT— Pavlovian fear conditioning is a widely used model of the acquisition and extinction of fear. Neural findings suggest that the amygdala is the core structure for fear acquisition, whereas prefrontal cortical areas are given pivotal roles in fear extinction. Forty-eight volunteers participated in a fear-conditioning experiment, which used fear potentiation of the startle reflex as the primary measure to investigate the effect of two genetic polymorphisms (5-HTTLPR and COMTval158met) on conditioning and extinction of fear. The 5-HTTLPR polymorphism, located in the serotonin transporter gene, is associated with amygdala reactivity and neuroticism, whereas the COMTval158met polymorphism, which is located in the gene coding for catechol-O-methyltransferase (COMT), a dopamine-degrading enzyme, affects prefrontal executive functions. Our results show that only carriers of the 5-HTTLPR s allele exhibited conditioned startle potentiation, whereas carriers of the COMT met/met genotype failed to extinguish conditioned fear. These results may have interesting implications for understanding gene-environment interactions in the development and treatment of anxiety disorders. 相似文献

What are the determinants of students' interest in earning a PhD? In this study, we use a mixed-methods approach to pursue this question. Based on qualitative interview data, we develop a model in which academic motivation and academic achievement interact with contextual factors such as working conditions to influence career intentions. We then test this model using a sample of 229 students currently enrolled in master-level courses of study at a German university. Our results speak to the role of intrinsic versus extrinsic motivations in the context of PhD intentions. In contrast to our expectations, results suggest that while intrinsic life aspirations and the intellectual challenge of gaining a PhD play a significant role for students' intention to pursue a PhD, extrinsic life aspirations and contextual determinants seem to be less influential. Furthermore, results highlight the importance of gaining familiarity and experience with academic work for students' career decisions. 相似文献

Because we humans have a multitude of relationships, which first allow us to live, dreams as a natural phenomenon can express this basic feature of humans but they can also be understood specially for various relationships: they depict multiple relationships in which we are involved, illuminate relationships, give another new component to conscious knowledge and in this way alter relationships. We tell each other about dreams and exchange them amongst ourselves in a special narrative sphere.When working with dreams in the therapeutic process, the messages of dreams on the analytical relationship are important information and experiences from an unaccustomed perspective. That both the analysand and the analyst share an understanding of the dreams, is shown in particular by the initial dream. It can conclusively be shown in dream series how relationship conflicts change through the work with dreams. 相似文献

There is a view that faces and objects are processed by different brain mechanisms. Different factors may modulate the extent to which face mechanisms are used for objects. To distinguish these factors, we present a new parametric multipart three-dimensional object set that provides researchers with a rich degree of control of important features for visual recognition such as individual parts and the spatial configuration of those parts. All other properties being equal, we demonstrate that perceived facelikeness in terms of spatial configuration facilitated performance at matching individual exemplars of the new object set across viewpoint changes (Experiment 1). Importantly, facelikeness did not affect perceptual discriminability (Experiment 2) or similarity (Experiment 3). Our findings suggest that perceptual resemblance to faces based on spatial configuration of parts is important for visual recognition even after equating physical and perceptual similarity. Furthermore, the large parametrically controlled object set and the standardized procedures to generate additional exemplars will provide the research community with invaluable tools to further understand visual recognition and visual learning. 相似文献

This multi-source diary study examined the role of partners for employees' daily recovery in a sample of dual-earner couples. We hypothesized that employees' daily psychological detachment from work during the evening should be positively associated with their partners' daily psychological detachment during the evening. Employees' affective well-being (serenity and negative activation) at bedtime should be influenced not only by their own psychological detachment, but also by their partners' psychological detachment. Moreover, we hypothesized that the presence of children in a couple's household should moderate the relations between partners' psychological detachment on the one hand, and employees' psychological detachment and affective well-being on the other hand. Fifty-three dual-earner couples completed daily electronic surveys via handheld devices at bedtime over the course of one work week. We used dyadic multilevel path modeling to analyze our data. Results showed that employees' and their partners' levels of daily psychological detachment were positively related. Employees' psychological detachment predicted their own negative activation, but not their serenity at bedtime. Partners' psychological detachment predicted employees' serenity and negative activation only in couples without children. Hence, our study provides support for the relevance of partners and children for employees' daily recovery after work. 相似文献
