The naive theory of vagueness holds that the vagueness of an expression consists in its failure to draw a sharp boundary between positive and negative cases. The naive theory is contrasted with the nowadays dominant approach to vagueness, holding that the vagueness of an expression consists in its presenting borderline cases of application. The two approaches are briefly compared in their respective explanations of a paramount phenomenon of vagueness: our ignorance of any sharp boundary between positive and negative cases. These explanations clearly do not provide any ground for choosing the dominant approach against the naive theory. The decisive advantage of the former over the latter is rather supposed to consist in its immunity to any form of sorites paradox. But another paramount phenomenon of vagueness is higher-order vagueness: the expressions (such as ‘borderline’ and ‘definitely’) introduced in order to express in the object language the vagueness of the object language are themselves vague. Two highly plausible claims about higher-order vagueness are articulated and defended: the existence of “definitely ω ” positive and negative cases and the “radical” character of higher-order vagueness itself. Using very weak logical principles concerning vague expressions and the ‘definitely’-operator, it is then shown that, in the presence of higher-order vagueness as just described, the dominant approach is subject to higher-order sorites paradoxes analogous to the original ones besetting the naive theory, and therefore that, against the communis opinio, it does not fare substantially better with respect to immunity to any form of sorites paradox.  相似文献

Intellectualism is the doctrine that knowing how to do something consists in knowing that something is the case. Drawing on contemporary linguistic theories of indirect interrogatives, Jason Stanley and Timothy Williamson have recently revived intellectualism, proposing to interpret a sentence of the form ‘DP know how to VP’ as ascribing to DP knowledge of a certain way w of VPing that they could VP in w. In order to preserve knowledge-how’s connection to action and thus avoid an overgeneration problem, they add that this knowledge must be had under a “practical” mode of presentation of w. I argue that there can be non-knowledgeable true beliefs under a practical mode of presentation and that some such beliefs would nevertheless be sufficient to establish knowledge-how’s characteristic connection to action, and thus count as knowledge-how. If so, Stanley and Williamson’s account is faced with a serious undergeneration problem. Moreover, the structural features on which the argument relies make it likely to present a quite general challenge for intellectualist strategies.  相似文献

Since cognitive neuroscience aims at giving an integrated account of mind and brain, its ontology should include both neural and cognitive entities and specify their relations. According to what we call the standard ontological framework of cognitive neuroscience (SOFCN), the aim of cognitive neuroscience should be to establish one-to-one mappings between neural and cognitive entities. Where such entities do not yet closely align, this can be achieved by reforming the cognitive ontology, the neural ontology, or both. In order to assess the limits and the possibilities of the SOFCN, we will examine a paradigmatic case study: the concept of Broca’s area, which indicates an alleged mapping between the left inferofrontal gyrus and the production of language. We review evidence showing that such a mapping does not hold, thus calling into question either the status of Broca’s area or the validity of the SOFCN. We then propose some strategies for addressing the issue and suggest that it may be solved within the SOFCN by adopting both of the following strategies: first, more accurately defining the relevant neural structures and second, switching the focus of neural ontology from structures to events, individuated by a where (neural structures) conjoint with a how (oscillatiory frequency).  相似文献

One of the main difficulties in the study of emotion is the induction of a real emotional response by means of artificial techniques. The aim of the current study is to validate the Spanish version of a set of films with the capacity to induce emotions (PIE) under laboratory conditions and to analyze its capacity to provoke differentiated basic emotions. A sample of 127 subjects took part in the study; 57 excerpts of Spanish-dubbed films with capacity in previous studies to induce 7 emotions: anger, fear, sadness, disgust, amusement, tenderness, and neutral emotion were used. Subjective emotional response was measured using the Self-Assessment Manikins and the Discrete Emotions Questionnaire. Films included showed a good capacity to induce positive and negative affects, high levels of emotional activation and variations in the perception of emotional control. They induced basic emotions of amusement and fear in a differentiated way. However, sadness and disgust could not be significantly differentiated from anger; or anger and tenderness from sadness. The PIE could be a useful tool for the experimental research of emotions in Spanish populations.  相似文献

Methods for detecting depression in fathers after the birth of their child are scarce. The Edinburgh Postnatal Depression Scale (EPDS), used to screen mothers for postpartum depression (PPD), lacks somatization and externalizing items. This potentially decreases its sensitivity in detecting depression in fathers, as many men actually express depression with somatization or externalizing symptoms. The present study assessed depressive symptoms in fathers of children 0–18 months old, and evaluated whether addressing both typical depression and externalizing, so‐called “depressive equivalent” symptoms, might be more suitable for such assessment. The Beck Depression Inventory‐II (BDI‐II), EPDS, and Gotland Male Depression Scale (GMDS) were responded to by 447 Swedish fathers online. Among participants, 27% reported depressive symptoms above the BDI‐II cut‐off suggestive of depression. Most fathers reported both traditional and depressive equivalent symptoms and a subgroup expressed exclusively depressive equivalent symptoms. Consistently, a scale combining items from the EPDS and GMDS showed higher sensitivity than the EPDS alone in identifying fathers with elevated depressive symptoms, at equal levels of specificity. Our findings suggest that a combination of EPDS and depressive equivalent symptom items results in a more suitable instrument for screening for depression in fathers during the postnatal period.  相似文献

Mothers (N= 35) and their adult children completed questionnaires and were interviewed in order to examine relationships between mothers' caregiving representations and their adult children's attachment representations, and relationships between attachment/caregiving representations and beliefs about mothering. Mothers' and their children's accounts of and present thinking about their past relationship were highly similar, indicating that the two parts develop concordant states of mind regarding their relationship. In contrast, there was no relationship between mothers' and their adult children's beliefs about mothering, suggesting that such beliefs are not simply passed on from generation to generation within families. Attachment/caregiving classification interacted with generation in influencing a belief that biological facts determine maternal behavior, young adults with preoccupied attachment being particularly prone to reject this idea. Attachment/caregiving classification also had a significant effect on participants' tendency to adhere to an idealized conception of mothering, this tendency being associated with a dismissive attachment/caregiving representation.  相似文献

Word-fragment completion is a frequently used test in implicit memory research. In this test priming is the relevant variable. Priming is obtained by subtracting the proportion of nonstudied word fragments correctly completed (called "completion difficulty baseline") from the studied word fragments correctly completed. Since completion difficulty can spuriously vary greatly between experimental conditions, its effect on magnitude of priming is studied. Normative frequency of occurrence of target words was considered because their influence over performance is known. In an experiment using a word-fragment completion test, participants' completion of fragments at three levels of completion difficulty and two levels of frequency was tested. Analysis showed that completion difficulty had a significant effect on global priming. The priming magnitude was higher for Difficult and Moderately Difficult fragments than for Easy ones. An interaction between fragment difficulty and normative word frequency was observed. When the fragments were easy to complete, the expected effect of higher priming for low-frequency words than for high-frequency words was not observed.  相似文献

The objective of the study is to explore the relationship of authentic leadership with work engagement and organizational citizenship behaviors (OCB) in military units, measuring the mediating effect of personal identification with the leader and social identification with the military unit. We used the Structural Equation Modeling (SEM) technique to analyze data from a sample of 225 Spanish military troops. The results showed that social identification with the military unit influenced the relationship of authentic leadership with the outcome variables.  相似文献

The objective of this paper is analyzing to which extent the multiverse hypothesis provides a real explanation of the peculiarities of the laws and constants in our universe. First we argue in favor of the thesis that all multiverses except Tegmark’s “mathematical multiverse” are too small to explain the fine tuning, so that they merely shift the problem up one level. But the “mathematical multiverse" is surely too large. To prove this assessment, we have performed a number of experiments with cellular automata of complex behavior, which can be considered as universes in the mathematical multiverse. The analogy between what happens in some automata (in particular Conway’s “Game of Life") and the real world is very strong. But if the results of our experiments can be extrapolated to our universe, we should expect to inhabit—in the context of the multiverse—a world in which at least some of the laws and constants of nature should show a certain time dependence. Actually, the probability of our existence in a world such as ours would be mathematically equal to zero. In consequence, the results presented in this paper can be considered as an inkling that the hypothesis of the multiverse, whatever its type, does not offer an adequate explanation for the peculiarities of the physical laws in our world.  相似文献
