Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who were matched on age, IQ, reading ability, and working memory. Children with DD were slower and less accurate during problem solving than TD children, and were especially impaired on their ability to solve subtraction problems. Children with DD showed significantly greater activity in multiple parietal, occipito‐temporal and prefrontal cortex regions while solving addition and subtraction problems. Despite poorer performance during subtraction, children with DD showed greater activity in multiple intra‐parietal sulcus (IPS) and superior parietal lobule subdivisions in the dorsal posterior parietal cortex as well as fusiform gyrus in the ventral occipito‐temporal cortex. Critically, effective connectivity analyses revealed hyper‐connectivity, rather than reduced connectivity, between the IPS and multiple brain systems including the lateral fronto‐parietal and default mode networks in children with DD during both addition and subtraction. These findings suggest the IPS and its functional circuits are a major locus of dysfunction during both addition and subtraction problem solving in DD, and that inappropriate task modulation and hyper‐connectivity, rather than under‐engagement and under‐connectivity, are the neural mechanisms underlying problem solving difficulties in children with DD. We discuss our findings in the broader context of multiple levels of analysis and performance issues inherent in neuroimaging studies of typical and atypical development. 相似文献

The concept of inhibition plays a major role in cognitive psychology. In the present article, we review the evidence for the
inhibition of task sets. In the first part, we critically discuss empirical findings of task inhibition from studies that
applied variants of the task-switching methodology and argue that most of these findings— such as switch cost asymmetries—are
ambiguous. In the second part, we focus on n-22 task-repetition costs, which currently constitute the most convincing evidence for inhibition of task sets. n-22 repetition costs refer to the performance impairment in sequences of the ABA type relative to CBA, which can be interpreted
in terms of persisting inhibition of previously abandoned tasks. The available evidence suggests that inhibition is primarily
triggered by conflict at selection of stimulus attributes and at the response level. Author Note 相似文献

Until fairly recently, positions within the global justice debate have been quite polarised along the statism/cosmopolitanism dichotomy. Recently, the dichotomy has been challenged (although somewhat unsystematically), but the idea that the proximity of a view to cosmopolitanism also tracks its critical potential in political terms has not. This article rejects this premise. In order to do so, it also provides a novel, more systematic challenge to the statism/cosmopolitanism dichotomy. The main suggestion is that we should consider two aspects simultaneously, and identify positions within the debate on the basis of how they relate to both of these. First of all, participants in the debate can make three different kinds of claims, which I shall call moral, political, and institutional. Secondly, views position themselves within a spectrum in each of the three dimensions, rather than deciding between cosmopolitanism and statism – and at different at different points of the spectrum with regard to their moral, political, and institutional commitments respectively. This account gives us a better grasp of what taking a stand in the global justice entails. Crucially, it enables us to understand that the transformative and critical potential of a specific view depends on a variety of factors, and not only on its stand at the moral level. One can be fairly critical of the status quo without endorsing a cosmopolitan, or even nearly cosmopolitan, moral outlook. In short, the moral story is not the whole story. 相似文献

Using a random sample of 243 Muslims in Lebanon and Syria, we examined whether support for Hezbollah or for Al Qaeda is predicted by functionally-relevant emotional responses to specific threats perceived to be posed by Americans. In line with the sociofunctional approach, perceived resource domination threat from Americans elicited anger, and perceived value contamination threat elicited disgust/contempt toward Americans. Importantly, these intergroup emotions in turn differentially predicted support for Hezbollah and Al Qaeda through desires for the organizations to accomplish different goals to address the threat perceptions. Specifically, anger toward Americans predicted support for Hezbollah through desires for the organization to restore threatened symbolic resources by bringing pride and respect to Arabs. In contrast, disgust/contempt toward Americans predicted support for Al Qaeda through desires for the organization to protect threatened ingroup values by de-contaminating Islam from Western cultural influence. Theoretical explanations and implications for addressing and mitigating hostilities between the groups are discussed. 相似文献

This study jointly examined illness beliefs held by persons with multiple sclerosis (PwMS) and caregivers in relation to well-being. A group of 68 PwMS and their caregivers completed the Revised Illness Perception Questionnaire, Psychological Well-being Scales, Satisfaction with Life Scale and Positive Affect and Negative Affect Schedule. Findings revealed that PwMS’ well-being was primarily predicted by their own illness beliefs, and that also caregivers’ well-being was primarily predicted by their own beliefs. Across the two groups, well-being was positively associated with their belief that they understood the disease, and inversely associated with their representations of negative emotions. In addition, among PwMS, well-being was inversely associated with the number of symptoms they specifically attributed to their illness, while among caregivers, well-being was positively associated with beliefs that treatment could control the disease. Based on the study findings, psychoeducational and cognitive-behavioral strategies are suggested to promote well-being among PwMS and caregivers. 相似文献

Women do not have a uniform or standardized “suit” to wear in the workplace so they must make daily decisions about what to wear. Some propose that women should dress in a sexualized way to gain power and influence, but sexy attire is related to lower perceptions of competence for women in leadership positions. We explored the effect of revealing or conservative attire on perceptions of women’s leadership competence. We also used eye-tracker technology to determine whether looking at sexualized body parts (i.e., breasts, hemline) was related to lower perceptions of leadership competence and electability. A female candidate for a student senate presidency at a U.S. university wearing revealing clothing was perceived by 191 college students as less honest and trustworthy, electable, and competent than one wearing conservative clothing. Sexualized body parts were looked at longer when the candidate was wearing revealing clothing compared to conservative clothing. Furthermore, mediation analyses indicated that the revealing clothing led participants to gaze at sexualized body parts, which, in turn, led to perceiving the candidate as less honest/trustworthy, which lowered their evaluations of her competence and electability. These findings suggest that viewing a woman in a sexy outfit can lead others to stare more at her body and make negative evaluations of her personal attributes. This finding has implications for the choices women make in workplace and leadership contexts. 相似文献

Bridging team faultlines by combining task role assignment and goal structure strategies 总被引:1,自引:0,他引:1
This study tests whether the detrimental effects of strong diversity faultlines on team performance can be counteracted by combining 2 managerial strategies: task role crosscutting and superordinate goals. We conducted a 2 (crosscut vs. aligned roles) × 2 (superordinate vs. subgroup goals) experimental study. Seventy-two 4-person teams with faultlines stemming from gender and educational major performed a complex decision-making task. The results show that teams with crosscut roles perform better when they are assigned a superordinate goal than a subgroup goal, whereas teams with aligned roles are not affected by goal manipulations. This effect is mediated by elaboration of task-relevant information. Implications for theory and management of team faultlines are discussed. 相似文献

The purpose of this paper is to develop a theoretical, yet practical framework for managing unrealistic expectations of expatriate marketing managers relative to their role in complex global marketing assignments. The formation of these unrealistic expatriate marketing managers’ expectations is examined using relational contracting theory. We explore alternative HRM evaluation/support designs that can suppress the development of expatriate marketing managers’ entitlement process and thus enhance the reality of expatriate marketing managers’ expectations relative to the role in a subsidiary of the multinational enterprise. 相似文献

Members of higher status groups generalize characteristics of their ingroup to superordinate categories that serve as a frame of reference for comparisons with outgroups (ingroup projection). We propose that the causal process depends on the security of the intergroup context: When intergroup relations are secure, projection derives from a motivation to represent the superordinate category efficiently; when they are insecure, projection is a defense motivated process. Accordingly, we hypothesized that inducing participants to use heuristic vs. systematic information processing (via time pressure, cognitive load, or thoughtfulness instructions) would have differential effects on ingroup projection in secure as compared to insecure intergroup relations. Three experiments manipulated security of the intergroup context and information processing mode in artificial (Studies 1 and 2) or natural (Study 3) groups. We found that time pressure increased ingroup projection in the secure-group condition but decreased it in the insecure-group condition (Study 1), cognitive load increased projection in the secure but not in the insecure condition (Study 2) and thoughtfulness instructions increased projection for high identifiers in the insecure but not in the secure condition (Study 3). Results support the hypothesis that ingroup projection occurs as a cognitive bias in secure intergroup relations but that it is socially motivated by the specific intergroup relation when this relation is insecure. 相似文献
