The writings of Kuhn and Feyerabend on incommensurability challenged the idea that science progresses towards the truth. Davidson famously criticized the notion of incommensurability, arguing that it is incoherent. Davidson's argument was in turn criticized by Kuhn and others. This article argues that, although at least some of the objections raised against Davidson's argument are formally correct, they do it very little harm. What remains of the argument once the objections have been taken account of is still quite damaging to the thesis that formerly endorsed scientific theories are incommensurable with those of today's science. 相似文献

Gender may be involved in the motivational processing of facial beauty. This study applied a behavioral probe, known to activate brain motivational regions, to healthy heterosexual subjects. Matched samples of men and women were administered two tasks: (a) key pressing to change the viewing time of average or beautiful female or male facial images, and (b) rating the attractiveness of these images. Men expended more effort (via the key-press task) to extend the viewing time of the beautiful female faces. Women displayed similarly increased effort for beautiful male and female images, but the magnitude of this effort was substantially lower than that of men for beautiful females. Heterosexual facial attractiveness ratings were comparable in both groups. These findings demonstrate heterosexual specificity of facial motivational targets for men, but not for women. Moreover, heightened drive for the pursuit of heterosexual beauty in the face of regular valuational assessments, displayed by men, suggests a gender-specific incentive sensitization phenomenon. 相似文献

A new instrument has been developed that allows a comprehensive assessment of the relevant dimensions of the phenomenology of autobiographical memories (Assessment of the Phenomenology of Autobiographical Memory, APAM), and their association with visual object and spatial imagery has been examined. An initial version of APAM consisting of 30 items (the first 28 measured on a seven-point Likert-type scale) was developed and administered to a sample of 138 undergraduates. To test whether each item consistently measured the same dimension across different memories, all questions were rated for 12 cues. Results showed that 25 Likert-type items possessed adequate levels of internal consistency and unidimensionality across cues. We also found that higher levels of visual object imagery were associated with more sensory details and recollective qualities of memory, and with stronger experience of sensory and emotional reliving. The theoretical and practical usefulness of APAM as well as the relevance of visual object imagery in the phenomenology of autobiographical memory are discussed. 相似文献

This paper discusses the issue of categorical acceptability of indicative and concessive conditionals. It presents experimental results in favour of two claims concerning the role of the evidential support relation for acceptability (or otherwise) of conditionals of both types. In particular, the results show that, contrary to fairly standard philosophical theorising, high probability of a conditional's consequent given its antecedent is necessary but not sufficient for the acceptability of that conditional, and that the antecedent being evidence for the consequent is a further acceptability condition. The results further show that the evidential support relation is crucial in differentiating between the acceptability of an indicative conditional and the acceptability of the corresponding concessive conditional: typically, the use of a concessive conditional signals that the corresponding conditional probability is high in spite of the fact that the antecedent is evidence against the consequent, or in any case is not evidence for the consequent. 相似文献

Putnam’s internal realism is aimed at reconciling realist and antirealist intuitions about truth and the nature of reality.
A common complaint about internal realism is that it has never been stated with due precision. This paper attempts to render
the position precise by drawing on the literature on conceptual spaces as well as on earlier work of the authors on the notion
of identity. 相似文献

Obsessive-compulsive disorders are associated with different neuropsychological impairments concerning executive functions, error monitoring, decision making and other basic functionalities. Contemporary neurocircuitry models emphasize the dysfunction of the fronto-striato-thalamo-cortical network related to parietal regions, the orbitofrontal cortex, the anterior cingulate cortex and other limbic structures. In brief, studies on the functional neuroanatomy of psychotherapy effects realized by positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) are reported. Perspectives concern combined process-outcome research with repeated neuroimaging and highly resolved (daily) self-ratings focussing the nonlinear dynamics of psychotherapeutic change processes. New therapeutic approaches could explore the combination of psychotherapy with fMRI-based real-time neurofeedback and noninvasive neuromodulation with coordinated reset stimulation focusing on the desynchronization of pathologically oversynchronized neural populations and networks. 相似文献

The stress associated with providing care for a spouse diagnosed with Alzheimer's disease can have adverse effects on cardiovascular health. One potential explanation is that chronic caregiving stress may contribute to the development of atherosclerosis. The purpose of this study was to determine whether the duration that one has provided care is associated with the degree of atherosclerotic burden, as measured by carotid artery intima-media thickness (IMT). One hundred and ten Alzheimer caregivers [mean age 74?±?8 (SD) years, 69% female] underwent in-home assessment of carotid artery IMT via B-mode ultrasonography. Data regarding medical history, blood pressure, and multiple indicators of caregiving stress were also collected. Multiple regression indicated that duration of care was positively associated with IMT measured in the internal/bifurcation segments of the carotid artery (β?=?0.202, p?=?0.044) independent of risk factors such as age, gender, body mass index, smoking history, sleep quality, hypertension status, and caregiving stressors. Duration of care was positively associated with IMT in the common carotid artery, but the relationship was not significant. These findings provide more evidence of the link between chronic caregiving stress and cardiovascular disease and indicate that enduring the experience of caregiving over a period of years might be associated with atherosclerotic burden. 相似文献

Mindwandering (MW) is associated with both positive and negative outcomes. Among the latter, negative mood and negative cognitions have been reported. However, the underlying mechanisms linking mindwandering to negative mood and cognition are still unclear. We hypothesized that MW could either directly enhance negative thinking or indirectly heighten the accessibility of negative thoughts. In an undergraduate sample (n=79) we measured emotional thoughts during the Sustained Attention on Response Task (SART) which induces MW, and accessibility of negative cognitions by means of the Scrambled Sentences Task (SST) after the task. We also measured depressive symptoms and rumination. Results show that in individuals with elevated levels of depressive symptoms MW during SART predicts higher accessibility of negative thoughts after the task, rather than negative thinking during the task. These findings contribute to our understanding of the underlying mechanisms of MW and provide insight into the relationship between task-involvement and affect. 相似文献

Psillos has recently argued that van Fraassen's arguments against abduction fail. Moreover, he claimed that, if successful, these arguments would equally undermine van Fraassen's own constructive empiricism, for, Psillos thinks, it is only by appeal to abduction that constructive empiricism can be saved from issuing in a bald scepticism. We show that Psillos' criticisms are misguided, and that they are mostly based on misinterpretations of van Fraassen's arguments. Furthermore, we argue that Psillos' arguments for his claim that constructive empiricism itself needs abduction point up to his failure to recognize the importance of van Fraassen's broader epistemology for constructive empiricism. Towards the end of our paper we discuss the suspected relationship between constructive empiricism and scepticism in the light of this broader epistemology, and from a somewhat more general perspective. 相似文献
