During the execution of a cognitive task, the brain maintains contextual information to guide behavior and achieve desired goals. The AX-Continuous Performance Task is used to study proactive versus reactive cognitive control. Young adults tend to behave proactively in standard testing conditions. However, it remains unclear how interindividual variability (e.g., in cognitive and motivational factors) may drive people into more reactive or proactive control under the same task demands. We investigated the use of control strategies in a large population of healthy young adults. We computed the proactive behavioral index and consequently divided participants into proactive, reactive, and intermediate groups. We found that reactive participants were generally slower, presented lower context sensitivity, and larger response variability. Pupillary changes and blink rate index cognitive effort allocation. We measured, concomitantly to the task, the pupil size and frequency of blinks associated with the cue maintenance and response intervals. During the cue period, nonfrequent, nontarget cues led to increased pupil dilation and number of blinks in all participants. During the response interval, we found more errors and increased pupil dilation to the probe when all participants had to overcome a response bias generated by the frequent cue. Only reactive participants showed larger response-related pupil when they had to overcome a response bias related to the frequent probe. Contrary to expectations, groups did not differ in ocular measures in the cue period. In conclusion, interindividual differences in cognitive control between healthy adults can be mapped onto different patterns of effort allocation indexed by the pupil. 相似文献

Since the advent of the concept of empathy in the scientific literature, it has been hypothesized, although not necessarily empirically verified, that empathic processes are essential to aesthetic experiences of visual art. We tested how the ability to “feel into” (“Einfühlung”) emotional content—a central aspect of art empathy theories—affects the bodily responses to and the subjective judgments of representational and abstract paintings. The ability to feel into was measured by a standardized pre-survey on “emotional contagion”—the ability to pick up and mirror, or in short to “feel into”, emotions, which often overlaps with higher general or interpersonal empathetic abilities. Participants evaluated the artworks on several aesthetic dimensions (liking, valence, moving, and interest), while their bodily reactions indicative of empathetic engagement (facial electromyography—EMG, and skin conductance responses—SCR) were recorded. High compared to low emotion contagion participants showed both more congruent and more intense bodily reactions (EMG and SCR) and aesthetic evaluations (higher being moved, valence, and interest) and also liked the art more. This was largely the case for both representational and abstract art, although stronger with the representational category. Our findings provide tentative evidence for recent arguments by art theorists for a close “empathic” mirroring of emotional content. We discuss this interpretation, as well as a potential tie between emotion contagion and a general increase in emotion intensity, both of which may impact, in tandem, the experience and evaluation of art. 相似文献

Earlier studies have explored post-identification experiences of male BRCA1/2 mutation carriers, but more detailed knowledge of both their experiences and effects of identification as a carrier on their lives is required to improve genetic counseling. Thus, the aim of this study was to acquire deeper and broader insights into their experiences. Qualitative data were collected from theme-based interviews with 31 men carrying BRCA1/2 mutations in Finland, and analyzed using inductive content analysis. Three categories of the participants’ responses to identification as BRCA1/2 mutation carriers were identified (personal, offspring-related and related to other relatives), mainly concerning issues associated with cancer, hereditary transmission of their mutations, and life decisions. Although there were many neutral responses regarding the issues, there were also strong emotional reactions and cancer worries. Identification as a carrier also had several effects on participants’ lifestyles, including adoption of healthier and disease-preventing behavior, and social well-being, such as family planning and attitudes to life. The results provide detailed information about several aspects of male BRCA1/2 mutation carriers’ experiences, which could be used to develop a tentative model of tailored genetic counseling for them. 相似文献

Important theoretical basic principles of the psychodynamic treatment of patients with antisocial and psychopathic personality disorders are presented. Focusing on delinquency and general orientation to the structural level of the personality organization should be integrated. Indications of treatment difficulties, countertransference problems and technical principles are given. Skepticism of the treatment is poorly evidence-based and forensic psychotherapy of these patient groups should be intensified. 相似文献

Previous research reported ambiguous findings regarding the relationship of visuospatial attention and (stereoscopic) depth information. Some studies indicate that attention can be focused on a distinct depth plane, while other investigations revealed attentional capture from irrelevant items located in other, unattended depth planes. To evaluate whether task relevance of depth information modulates the deployment of attentional resources across depth planes, the additional singleton paradigm was adapted: Singletons defined by depth (i.e., displayed behind or in front of a central depth plane) or color (green against gray) were presented among neutral items and served as targets or (irrelevant) distractors. When participants were instructed to search for a color target, no attentional capture from irrelevant depth distractors was observed. In contrast, it took substantially longer to search for depth targets when an irrelevant distractor was presented simultaneously. Color distractors as well as depth distractors caused attentional capture, independent of the distractors’ relative depth position (i.e., in front of or behind the target). However, slight differences in task performance were obtained depending on whether or not participants fixated within the target depth plane. Thus, the current findings indicate that attentional resources in general are uniformly distributed across different depth planes. Although task relevant depth singletons clearly affect the attentional system, this information might be processed subsequent to other stimulus features. 相似文献

Procrastination is a common problem among university students, with at least half of the population reporting great difficulties initiating or completing tasks and assignments. Procrastination can have a negative impact on course grades and the ability to achieve a university degree, but can also lead to psychological distress. Cognitive behavior therapy (CBT) is believed to reduce procrastination, but few studies have investigated its effectiveness in a regular clinical setting. The current study explored its effects using a pragmatic randomized controlled trial comparing treatment delivered during 8 weeks as self-guided CBT via the Internet (ICBT) or as group CBT. In total, 92 university students with severe procrastination were included in the study (registered as a clinical trial on Clinicaltrials.gov: NCT02112383). Outcome measures on procrastination, depression, anxiety, and well-being were distributed at pre- and posttreatment as well as 6-month follow-up. An outcome measure of procrastination was administered weekly. Linear mixed and fixed effects models were calculated, along with improvement and deterioration rates. The results showed large within-group effect sizes on procrastination, Cohen’s d of 1.29 for ICBT, 95% Confidence Interval (CI) [0.81, 1.74], and d of 1.24 for group CBT, 95% CI [0.76, 1.70], and small to moderate benefits for depression, anxiety, and well-being. In total, 33.7% were regarded as improved at posttreatment and 46.7% at follow-up. No differences between conditions were observed after the treatment period, however, participants in group CBT continued or maintained their improvement at follow-up, while participants in self-guided ICBT showed some signs of deterioration. The findings from the current study suggest that CBT might be an effective treatment for those struggling with severe procrastination, but that a group format may be better for some to sustain their benefits over time and that the clinical significance of the results need to be investigated further. 相似文献

Why do people engage in collective actions, such as demonstrations? We suggest that intentions to engage in protest activities come from the perception that the action is an efficient way to affect policy but is also dependent upon the level of others’ engagement. Specifically, lower support should spur intentions to engage if the individual believes that the collective act is an efficient means to bring about social change. In two experiments, manipulating social support, efficacy increased intentions to participate in collective actions but mainly for participants with low social support (Experiments 1 and 2). In Experiment 3, manipulating efficacy, high social support was related to decreased intentions to engage. However, in this study, social support did not interact with efficacy. 相似文献

This essay offers a critical analysis of Hannah Arendt's notion of natality through the lens of Adriana Cavarero's feminist philosophy of birth. First, I argue that the strength of Arendtian natality is its rootedness in an ontology of uniqueness, and a commitment to human plurality and relationality. Next, I trace with Cavarero three critical concerns regarding Arendtian natality, namely that it is curiously abstract; problematically disembodied and sexually neutral; and dependent on a model of vulnerability that assumes equality rather than asymmetry. This last issue is further developed in the final section of the essay, where I examine the idea that birth, for Cavarero, becomes the very concept by which we can distinguish and normatively differentiate acts of care and love from acts of wounding and violence. Upholding the normative distinction here depends on a conceptual distinction between vulnerability and helplessness. To maintain the ethical potential of the scene of birth, I argue that we have to insist on the very characteristics Cavarero attributes to it—ones, as this essay aims to show, that are ultimately missing in the Arendtian account thereof. 相似文献

This article offers an overview of what every theologian and scholar of religion should know about changes in biblical studies that have taken place concerning the past depreciation of Second Temple Judaism, the use of newly discovered sources and their implications, as well as integrative approaches to top-down (reflected beliefs, prescribed practices, textual sources) and bottom-up (intuitive beliefs, lived practices, material culture) processes. Changes in the field lead to the re-writing of the history of the Bible and of Judaean society in the Greco-Roman context. By means of this co-authored research article, we wish to demonstrate the benefit of, as well as the need for, interdisciplinary work in the study of antiquity. 相似文献

In this paper a new conception of foundation-oriented epistemology is developed. The major challenge for foundation-oriented justifications consists in the problem of stopping the justificational regress without taking recourse to dogmatic assumptions or circular reasoning. Two alternative accounts that attempt to circumvent this problem, coherentism and externalism, are critically discussed and rejected as unsatisfactory. It is argued that optimality arguments are a new type of foundation-oriented justification that can stop the justificational regress. This is demonstrated on the basis of a novel result in the area of induction: the optimality of meta-induction. In the final section the method of optimality justification is generalized to deductive and abductive inferences. 相似文献
