Access to other minds once presupposed other individuals’ expressions and narrations. Today, several methods have been developed which can measure brain states relevant for assessments of mental states without 1st person overt external behavior or speech. Functional magnetic resonance imaging and trace conditioning are used clinically to identify patterns of activity in the brain that suggest the presence of consciousness in people suffering from severe consciousness disorders and methods to communicate cerebrally with patients who are motorically unable to communicate. The techniques are also used non-clinically to access subjective awareness in adults and infants. In this article we inspect technical and theoretical limits on brain–machine interface access to other minds. We argue that these techniques hold promises of important medical breakthroughs, open up new vistas of communication, and of understanding the infant mind. Yet they also give rise to ethical concerns, notably misuse as a consequence of hypes and misinterpretations. 相似文献

This is a study of comorbid anxiety disorders and how they affect the clinical picture of comorbid cases. The sample consisted
of 576 Spanish children aged 8 to 17 years receiving psychiatric outpatient consultation that were evaluated using a semi-structured
diagnostic interview for both parents and children. A specific association of homotypic comorbidity among anxiety disorders
that was independent of the presence of other disorders was found. There was heterotypic comorbidity between anxiety and depressive
disorders, ADHD, anorexia and tic disorders. Relationships between non-anxiety disorders were, in general, independent of
anxiety, but anxiety moderated the relationship between ADHD-Conduct disorder and Conduct disorder-enuresis. Comorbid anxiety
increased difficulties in social interaction, was related with higher global impairment and had an impact on consultation
and medication. Anxiety disorder comorbidity should be well recognized in order not to disregard the treatment of all present
disorders. 相似文献

Even if there is a common morality, many would argue that it provides little guidance in resolving moral disputes, because
universally accepted norms are both general in content and few in number. However, if we supplement common morality with commonly
accepted factual beliefs and culture-specific norms and utilize coherentist reasoning, we can limit the range of acceptable
answers to disputed issues. Moreover, in the arena of public policy, where one must take into account both legal and moral
norms, the constraints on acceptable answers will narrow the extent of reasonable disagreement even further. A consideration
of the debate over legalization of assisted dying supports this claim.

Recent theoretical and empirical work suggests that explanation and categorization are intimately related. This paper explores the hypothesis that explanations can help structure conceptual representations, and thereby influence the relative importance of features in categorization decisions. In particular, features may be differentially important depending on the role they play in explaining other features or aspects of category membership. Two experiments manipulate whether a feature is explained mechanistically, by appeal to proximate causes, or functionally, by appeal to a function or goal. Explanation type has a significant impact on the relative importance of features in subsequent categorization judgments, with functional explanations reversing previously documented effects of ‘causal status’. The findings suggest that a feature’s explanatory importance can impact categorization, and that explanatory relationships, in addition to causal relationships, are critical to understanding conceptual representation. 相似文献

The Trail-Making Test (TMT) is a widely used neuropsychological measure that assesses visuomotor abilities and cognitive flexibility. For the TMT-A condition participants are required to locate and connect numbers (i.e. 1-2-3…) while in the TMT-B condition participants perform the set-shifting task of locating and connecting numbers and letters (i.e. 1-A-2-B…). The TMT-B condition has shown impairments in many clinical populations, particularly schizophrenia patients, but the neurobiological underpinning of the task can be difficult to discern given pragmatic obstacles in adapting the task for neuroimaging. In a behavioural testing experiment we demonstrated a close correspondence between performance on the standard TMT and a novel, computer programmed adaptation of the TMT (pcTMT). The pcTMT was designed for functional magnetic resonance imaging (fMRI) administration and neuroimaging data for this task were obtained in. A whole brain analysis revealed significantly greater activation during the pcTMT-B relative to the pcTMT-A in right inferior/middle frontal cortices, right precentral gyrus, left angular gyrus/left middle temporal gyrus. These results identify the regions that most likely underlie cognitive flexibility during the TMT and are candidate regions underlying the impairment of groups with poor set-shifting abilities. 相似文献

Research suggests that exposure to sociocultural norms for idealized appearance can reduce both women's and men's body satisfaction. Despite comparable effects for both genders in the lab, in the “real-world” women's body satisfaction is chronically lower than men's. Real-world gender differences may arise from discrepancies in men's and women's everyday exposure to norms. Across eight studies using a variety of content analysis, survey, and experimental methods, we examine differences in sociocultural norms for ideal appearance pertaining to women and men in “daily life” contexts. We demonstrate that appearance norms encountered by women in daily life are more rigid, homogenous and pervasive than those for men, and that more messages implying the attainability of the ideal appearance are directed at women. Finally, experimental results show that homogeneous, rigid norms (like those typically encountered by women) are more harmful to body image than heterogeneous, flexible norms (like those typically encountered by men). 相似文献

This paper is a rejoinder to papers by Sabina Lovibond, Nicholas Wolterstorff, Sumner B. Twiss, G. Scott Davis, M. Cathleen Kaveny, and John Kelsay on the author's recent book Democracy and Tradition. The argument covers a host of topics, ranging from epistemology and methodology to human rights, the common law, and Islamic ethics. 相似文献

Evidence from two experiments indicates that task-related communication promotes cooperation in mixed-motive situations by activating interpersonal norms related to fairness and trust. In Experiment 1, task-related communication increased cooperation between individuals in a three-choice prisoner’s dilemma game (PDG-Alt) but task-unrelated communication did not. In Experiment 2, cooperation was increased both by sending a task-related message to one’s counterpart and receiving a cooperative task-related message from one’s counterpart. Mediation analyses revealed that task-related communication increased cooperation by activating fairness and trust norms (Experiments 1 and 2). Specifically, whereas sending (relative to receiving) a task-related message increased cooperation by activating fairness norms, receiving (relative to sending) a task-related message increased cooperation by activating trust norms (Experiment 2). 相似文献
