This article has two primary aims. The first is to introduce a new Vietnamese text-based corpus. The Corpora of Vietnamese Texts (CVT; Tang, 2006a) consists of approximately 1 million words drawn from newspapers and children's literature, and is available online at www.vnspeechtherapy.com/vi/CVT. The second aim is to investigate potential differences in lexical frequency and distributional characteristics in the CVT on the basis of place of publication (Vietnam or Western countries) and intended audience: adult-directed texts (newspapers) or child-directed texts (children's literature). We found clear differences between adult- and child-directed texts, particularly in the distributional frequencies of pronouns or kinship terms, which were more frequent in children's literature. Within child- and adult-directed texts, lexical characteristics did not differ on the basis of place of publication. Implications of these findings for future research are discussed. 相似文献

The authors conducted an experience sampling study to investigate the relationship between momentary ruminative self-focus and negative affect. Ninety-three adults recorded these variables at quasi-random intervals 8 times daily for 1 week. Scores on questionnaire measures of dispositional rumination were associated with mean levels of momentary ruminative self-focus over the experience sampling week. Concurrently, momentary ruminative self-focus was positively associated with negative affect. Cross-lagged analyses revealed that whereas ruminative self-focus predicted negative affect at a subsequent occasion, negative affect also predicted ruminative self-focus at a subsequent occasion. Decomposition of the dispositional rumination measure suggested that brooding, but not reflective pondering, was associated with higher mean levels of negative affect. Though broadly consistent with Nolen-Hoeksema's (1991) response styles theory, these results suggest that a reciprocal relationship exists between ruminative self-focus and negative affect. 相似文献

Much work has been done to investigate participants' ability to detect repeated targets, but the presentstudy examined the influence of recently attended stimuli on target masking. Participants performed a target identification task in which the item that masked the target was either a recently attended item or a novel item. When it was identical to a previously attended stimulus, the mask was rendered considerably less effective. We have termed this effect a repeated mask reduction (RMR). This simple manipulation resulted in a large, reliable effect on the efficacy of visual masking in a single-target identification paradigm. In Experiments 1, 2, and 3, we demonstrated the basic effect and noted that the RMR increased as task difficulty increased. Experiments 4 and 5 suggested that attention to the first instance of the mask was crucial to this effect by showing that the magnitude of the RMR was unaffected by repetition of nonmask distractors and that the magnitude of the effect was reduced when less attention was paid to the first instance of the mask. 相似文献

We tested whether counterfactuals are made spontaneously outside of the laboratory by coding sportscasters’ online verbalizations during 1998 and 1999 Major League Baseball (MLB) playoff broadcasts, and we assessed whether naturally occurring game features relating to closeness (score closeness, series closeness, game end, and playoff end) delineated some conditions under which counterfactuals were more likely. Sportscasters made counterfactuals quite frequently during these MLB playoff games. In addition, sportscasters uttered greater numbers of counterfactuals as games progressed from early to late innings, which was particularly true when scores were close. Counterfactuals were also uttered in greater numbers with closer scores when series were tied than when one team had a lead. Results are discussed in terms of spontaneous counterfactuals, closeness as an antecedent, and the ecological validity of such thoughts. 相似文献

Consumer judgment often is based on incomplete or limited knowledge of the relevant attributes. We performed 3 experiments to investigate why these judgments are often insensitive to set size and why evaluations based on limited information tend to be stronger (more extreme and confident) than is warranted. The findings indicate that the importance of the given or known attributes is often overestimated, leading to evaluations that are overly extreme. The experiments also revealed important factors moderating this insensitivity to limited information. The overweighing of the given evidence was attenuated when participants were knowledgeable of the target domain. Overweighing and the formation of extreme judgments based on limited information was also diminished when participants considered their judgmental criteria prior to evaluating a target or when a comparison target described by different attributes was present. 相似文献

Philosophical discussions of the phenomenon that has come to be known as ‘moral luck’ have either dismissed it as illusory or touted it as the evidence for doubting the probative value of our commitment to certain widely avowed views concerning interpersonal assessments of responsibility. In this discussion, we present a third, distinctive interpretation of the moral luck phenomenon. Drawing upon empirically robust results from psychological studies of judgment bias, we argue that the phenomenon of moral luck is demonstrably not illusory. What we suggest, however, is that the phenomenon ought not to be taken to countenance doubts about the standards generally taken to be regulative of assessments of interpersonal responsibility. Rather, its significance lies in foregrounding certain generally unacknowledged obstacles we face in the process of conclusively applying general valid moral standards in making specific judgments of responsibility and desert.1 相似文献

Studies in 2 work organizations tested a self‐determination theory based model in which employees' autonomous causality orientation and their perceptions of their managers' autonomy support independently predicted satisfaction of the employees' intrinsic needs for competence, autonomy, and relatedness, which in turn predicted their performance evaluations and psychological adjustment. Path analysis indicated that the self‐determination theory model fit the data very well and that alternative models did not provide any advantage. 相似文献

Does unconscious perception at the objective detection threshold (ODT) exist? In this reply, formal meta-analyses of previously narratively reviewed evidence (Snodgrass, Bernat, & Shevrin, 2004) provide strong evidence for large, reliable unconscious perceptual effects, and further strengthen previous conclusions for their ODT status. These meta-analyses dispel general concerns that ODT effects are small, unreliable, or susceptible to file drawer concerns (cf. Reingold, 2004). Furthermore, the specific objections (Holender & Duscherer, 2004) to individual ODT effects are refuted, and objections to our proposed solutions to the exhaustiveness, exclusiveness, and null sensitivity problems (Haase & Fisk, 2004; Reingold, 2004) are shown to be inapplicable, contradicted by the available evidence, or both. Accordingly, the strong evidence for ODT effects, taken together with the nonmonotonic relationship, contradicts the single-process conscious perception model (e.g., Holender & Duscherer, 2004) and provides stronger evidence for unconscious perception than hitherto available. 相似文献

The present information explosion on the World Wide Web poses a problem for the general public and the members of an academic discipline alike, of how to find the most authoritative, comprehensive, and up-to-date information about an important topic. At the Stanford Encyclopedia of Philosophy (SEP), we have since 1995 been developing and implementing the concept of a dynamic reference work (DRW) to provide a solution to these problems, while maintaining free access for readers. A DRW is much more than a web-based encyclopedia, and its scope far exceeds that of an electronic journal or preprint exchange. In this article we document the progress of the SEP toward full implementation of the DRW concept. We discuss the fiscal challenges posed by our desire to maintain free or low-cost access to the contents of the SEP, and we consider technological challenges posed by the desire to stay abreast of technological developments in document markup while making it easy for authors and subject editors to write and maintain entries representing the very best scholarship. 相似文献
