Since the rise of mass politics, the role national identities play in international relations has been debated. Do they produce a popular reservoir easily tapped for war or bestow dignity thereby fostering cooperation and a democratic peace? The evidence for either perspective is thin, beset by different conceptions of identity and few efforts to identify its effects independent of situational factors. Using data drawn from new national surveys in Italy and the United States, we advance a three‐dimensional conception of national identity, theoretically connecting the dimensions to conflictive and cooperative dispositions as well as to decisions to cooperate with the United Nations in containing Iran's nuclear proliferation and Sudan's humanitarian crisis in Darfur. Attachment to the nation in Italy and the United States is found to associate with less support for militarist options and more support for international cooperation as liberal nationalists expect. This depends, however, on containing culturally exclusive conceptions of the nation and chauvinism. 相似文献

In the literature on apraxia of tool use, it is now accepted that using familiar tools requires semantic and mechanical knowledge. However, mechanical knowledge is nearly always assessed with production tasks, so one may assume that mechanical knowledge and familiar tool use are associated only because of their common motor mechanisms. This notion may be challenged by demonstrating that familiar tool use depends on an alternative tool selection task assessing mechanical knowledge, where alternative uses of tools are assumed according to their physical properties but where actual use of tools is not needed. We tested 21 left brain-damaged patients and 21 matched controls with familiar tool use tasks (pantomime and single tool use), semantic tasks and an alternative tool selection task. The alternative tool selection task accounted for a large amount of variance in the single tool use task and was the best predictor among all the semantic tasks. Concerning the pantomime of tool use task, group and individual results suggested that the integrity of the semantic system and preserved mechanical knowledge are neither necessary nor sufficient to produce pantomimes. These results corroborate the idea that mechanical knowledge is essential when we use tools, even when tasks assessing mechanical knowledge do not require the production of any motor action. Our results also confirm the value of pantomime of tool use, which can be considered as a complex activity involving several cognitive abilities (e.g., communicative skills) rather than the activation of gesture engrams. 相似文献

Facilitation on abstract versions of the selection task can be produced by deontic content. Jackson and Griggs (1990) claimed that this finding depends on the presence of an explicit negative on the not-q card. We hypothesized that the removal of the explicit negative from this card made its deontic status ambiguous. Experiment 1 demonstrated that a not-q card presenting implicit negative is not selected, and most subjects select the only card that appears to be relevant from a deontic point of view (i.e. the p card). Experiments 2 and 3 showed that the presence of the explicit negative on the not-q card is not necessary for producing facilitation, provided that the form of this card makes it clear that the not-q individual is a potential violator. Experiment 4 showed that a high success rate can be obtained even with a not-q card presenting an implicit negative. The results are discussed in terms of the specificity of reasoning in the deontic domain. 相似文献

Principal covariate regression (PCOVR) is a method for regressing a set of criterion variables with respect to a set of predictor variables when the latter are many in number and/or collinear. This is done by extracting a limited number of components that simultaneously synthesize the predictor variables and predict the criterion ones. So far, no procedure has been offered for estimating statistical uncertainties of the obtained PCOVR parameter estimates. The present paper shows how this goal can be achieved, conditionally on the model specification, by means of the bootstrap approach. Four strategies for estimating bootstrap confidence intervals are derived and their statistical behaviour in terms of coverage is assessed by means of a simulation experiment. Such strategies are distinguished by the use of the varimax and quartimin procedures and by the use of Procrustes rotations of bootstrap solutions towards the sample solution. In general, the four strategies showed appropriate statistical behaviour, with coverage tending to the desired level for increasing sample sizes. The main exception involved strategies based on the quartimin procedure in cases characterized by complex underlying structures of the components. The appropriateness of the statistical behaviour was higher when the proper number of components were extracted. 相似文献

Three experiments examined how people gather information on in-group and out-group members. Previous studies have revealed that category-based expectancies bias the hypothesis-testing process towards confirmation through the use of asymmetric-confirming questions (which are queries where the replies supporting the prior expectancies are more informative than those falsifying them). However, to date there is no empirical investigation of the use of such a question-asking strategy in an intergroup context. In the present studies, participants were asked to produce (Study 1) or to choose (Studies 2 and 3) questions in order to investigate the presence of various traits in an in-group or an out-group member. Traits were manipulated by valence and typicality. The results revealed that category-based expectancies do not always lead to asymmetric-confirming testing: whereas participants tended to ask questions that confirmed positive in-group and negative out-group stereotypical attributes, they used a more symmetric strategy when testing for the presence of negative in-group or positive out-group traits. Moreover, Study 3 also revealed a moderation effect of in-group identification. The findings point to the role played by motivational factors associated with preserving a positive social identity. Possible consequences of these hypothesis-testing processes in preserving a positive social identity for intergroup relations are discussed. 相似文献

Five experiments investigated the ability to discriminate between musical timbres based on vibrotactile stimulation alone. Participants made same/different judgments on pairs of complex waveforms presented sequentially to the back through voice coils embedded in a conforming chair. Discrimination between cello, piano, and trombone tones matched for F0, duration, and magnitude was above chance with white noise masking the sound output of the voice coils (Experiment 1), with additional masking to control for bone-conducted sound (Experiment 2), and among a group of deaf individuals (Experiment 4a). Hearing (Experiment 3) and deaf individuals (Experiment 4b) also successfully discriminated between dull and bright timbres varying only with regard to spectral centroid. We propose that, as with auditory discrimination of musical timbre, vibrotactile discrimination may involve the cortical integration of filtered output from frequency-tuned mechanoreceptors functioning as critical bands.

The aim of this study is to evaluate the correlation between different measures of quality of life (QoL), functional status and mood status in patients with amyotrophic lateral sclerosis (ALS). A sample of 40 patients with ALS was recruited and scales for the evaluation of health-related QoL (SF36), patient-centered QoL (SEIQoL), functional status (ALSFRS) and depression (ZDS) have been administered to them. All the correlations (Pearson's r) between the scores have been considered and the t-test was performed in order to compare male with female patients. No correlation emerged between the different measures of QoL and functional status, apart from the scores of the Physical Functioning subscale of the SF36 which resulted positively correlated (p?0.01) with those of the ALSFRS. Mood status resulted negatively correlated with many aspects of health-related QoL but not with patient-centred QoL. Data suggest that the relationship between functional status and different domains of QoL in this population of patients with a severely compromising disease is not linear and that the satisfaction with life of the patients themselves is not strongly related to the level of physical impairment. 相似文献

In this study, a multisensory methodology is used to assess acoustic comfort aboard different real‐world metros by means of subjective annoyance and cognitive performance measures. Two experimental conditions were compared: unimodal versus bimodal. Immersive virtual reality was used to simulate journeys aboard metro coaches. Participants performed four tasks (Rey Test, Verbal Fluency, Backward Counting and Auditory Words Discrimination) while listening to metro sounds (unimodal condition) or while listening to metro sounds within a virtual metro coach (bimodal condition). At the end of each journey, participants reported their degree of noise annoyance. The results showed that cognitive performances were worse in the bimodal than in the unimodal condition. Moreover, the bimodal condition affected negatively the capacity to discriminate words and to count backward. However, reported noise annoyance was higher in the unimodal than bimodal condition. The theoretical and practical implications of these findings are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献
