The present study tests the hypothesis that attention-switching is time-consuming and performance-limiting. Analysis of previous research on counting interaurally presented clicks shows that estimates of ‘switch-times’ can be made, based on the data of Guzy and Axelrod (1972). In the earlier click-counting studies, however, the number of clicks to be counted and the number of physical switches between the ears were confouned. Hence the number of clicks, number of physical switches and interval between clicks were independently varied. The results showed that (a) counting performance did not decrease monotonically with increasing number of switches in the click sequence; (b) no difference in counting performance could be found between the monaural and completely alternating interaural presentation; (c) when the number of switches in the sequence was small and equal groups of clicks alternated between ears, performance dramatically improved. With these kinds of sequences, subjects presumably do not count the clicks one at a time, but subitize a group of clicks. 相似文献

InWord and Object W. V. Quine argues that there is no uniquely correct way to assign referents to the terms of a language; any claim about the reference of a term is implicitly relative to a manual of translation. To Rudolf Carnap this must have seemed familiar. BeforeWord and Object was written Carnap had been saying the same thing inMeaning and Necessity: under the assumption of the method of the name-relation, any claim about the reference of a term is implicitly relative to what Carnap calls a conception of the name-relation. Yet Carnap is often taken to be a victim of Quine's relativistic notion of reference. Drawing on Carnap's discussion of the name-relation inMeaning and Necessity, it is argued that Carnap's and Quine's views on reference are not so far apart as is usually perceived.I would like to thank the referees who reviewed this paper for their helpful and insightful comments. In addition, I would like to thank Dr. Richard Creath both for his comments on earlier drafts of this paper as well as for conversations (beyond number) on these and many other issues related to the Quine-Carnap debate. Creath's own discussion of this topic entitled Functionalist Theories of Meaning and the Defense of Analyticity, appears in the volumeLanguage, Logic, and the Structure of Scientific Theories: The Carnap-Reichenbach Centennial, edited by W. Salmon and G. Wolters (Pittsburgh: University of Pittsburgh Press, and Konstanz, Germany: University of Konstanz Press, 1994). 相似文献

Bryden, McManus, and Bulman-Fleming′s (1994) meta-analysis of studies examining the Geschwind-Behan-Galaburda hypothesis indicates that the original data set supports the hypothesis significantly more than the body of replication attempts. We present data on 2256 subjects that clearly fail to support the hypothesis and describe practical and statistical reasons suggesting why the original data cannot be easily replicated. A power analysis suggests that to find the effect in a general sample, one should plan to have 17,000 to 40,000 subjects. 相似文献

Questions related to the uniqueness of language can only be addressed properly by referring to sound knowledge of the relevant cognitive abilities of nonhuman animals. A key question concerns the nature and extent of animal rule-learning abilities. I discuss two approaches used to assess these abilities. One is comparing the structures of animal vocalizations to linguistic ones, and another is addressing the grammatical rule- and pattern-learning abilities of animals through experiments using artificial grammars. Neither of these approaches has so far provided unambiguous evidence of advanced animal abilities. However, when we consider how animal vocalizations are analyzed, the types of stimuli and tasks that are used in artificial grammar learning experiments, the limited number of species examined, and the groups to which these belong, I argue that the currently available evidence is insufficient to arrive at firm conclusions concerning the limitations of animal grammatical abilities. As a consequence, the gap between human linguistic rule-learning abilities and those of nonhuman animals may be smaller and less clear than is currently assumed. This means that it is still an open question whether a difference in the rule-learning and rule abstraction abilities between animals and humans played the key role in the evolution of language. 相似文献

The positive relationship between religiosity and life satisfaction is well-established. This relationship is, however, likely to vary across cultural contexts and different religious affiliations. Furthermore, research is needed to uncover why religion is relevant for life satisfaction. Addressing these issues, we investigate what dimensions of being religious play a role in the life satisfaction of individuals with different religious affiliations, including the understudied Muslim category, in the highly secularized Dutch context. We examine ‘believing’, which captures how religion provides meaning and a coherent worldview, and ‘belonging’, which comprises both cultural benefits of being embedded in a congregation with a shared framework of meaning and structural benefits due to more social ties. Analyses of the NEtherlands Longitudinal Lifecourse Study (n = 5312) first indicate that Muslims display significantly lower life satisfaction than the non-religious, which appears to be due to their underprivileged social position rather than intra-religious factors of believing and belonging. Second, we find that Catholics experience significant life satisfaction benefits compared to those who are not religious, and that only belonging plays a role in this association. Next to the beneficial effect of the structural aspect of belonging, which revolves around social ties, a cultural aspect of religious belonging appears to be salient, suggesting that an important life satisfaction advantage of religious communities lies in their ability to foster a sense of solidarity and commitment through a shared framework of meaning. We make several recommendations for further research based on these findings. 相似文献

This paper explores the relevance of the debate about ethical expertise for the practice of clinical ethics. We present definitions, explain three theories of ethical expertise, and identify arguments that have been brought up to either support the concept of ethical expertise or call it into question. Finally, we discuss four theses: the debate is relevant for the practice of clinical ethics in that it (1) improves and specifies clinical ethicists' perception of their expertise; (2) contributes to improving the perception of moral competence of non-ethicists; (3) gives insight into complementary styles of argumentation of ethicists and non-ethicists; and (4) contributes to the awareness of the problem of profession-building of (clinical) ethicists. 相似文献

Abstract One hundred and eleven females volunteered to take part in this intervention study of musculoskeletal pain. They all completed a survey of pain among five hundred and eighty-six female hospital staff and presented mild to severe pain in the neck, shoulder and/or low back. They were randomly assigned to one of the following groups; Focus on job-stress and psychosocial coping (Cognitive), relaxation training (Relaxation), the combination of the two (Combined) or to a control group (Control). Musculoskeletal pain (intensity and duration) was assessed by self-report prior to interventions, immediately after interventions, and at a four months follow-up. Results from multivariate analyses of variance as well as covariance (pre-intervention levels of pain as covariate) showed that magnitude of pain reduction was dependent upon the interaction between area of the back and type of intervention. These trends were more significant for intensity than for duration scores. They were due to reductions of pain in (1) neck and shoulders for the Cognitive and Combined groups and (2) in the low back and shoulders for the Relaxation group. The four month follow-up assessment revealed a significant risk of relapse only for duration of low back pain among subjects in the Combined group. Results from the Cognitive approach to intervention may reflect a causal role for ability to cope with psychosocial job stress in the development of neck and shoulder pain in female hospital staff. 相似文献
