We use the results of a large online experiment on word knowledge in Dutch to investigate variables influencing vocabulary size in a large population and to examine the effect of word prevalence—the percentage of a population knowing a word—as a measure of word occurrence. Nearly 300,000 participants were presented with about 70 word stimuli (selected from a list of 53,000 words) in an adapted lexical decision task. We identify age, education, and multilingualism as the most important factors influencing vocabulary size. The results suggest that the accumulation of vocabulary throughout life and in multiple languages mirrors the logarithmic growth of number of types with number of tokens observed in text corpora (Herdan's law). Moreover, the vocabulary that multilinguals acquire in related languages seems to increase their first language (L1) vocabulary size and outweighs the loss caused by decreased exposure to L1. In addition, we show that corpus word frequency and prevalence are complementary measures of word occurrence covering a broad range of language experiences. Prevalence is shown to be the strongest independent predictor of word processing times in the Dutch Lexicon Project, making it an important variable for psycholinguistic research. 相似文献

Previous research has shown that ethnic school composition can have an impact on a number of outcomes for pupils. The influence ethnic school composition has on pupils’ religiosity, however, has not received much attention. Furthermore, the few previous studies that have examined this relationship have relied on cross‐sectional data, thus being unable to separate selection effects from causal effects. In this research note we use longitudinal data collected among pupils in the third (2011–2012) and sixth grade (2014–2015) of secondary schools in Flanders, the northern part of Belgium. We examine changes in religiosity among pupils using cross‐classified multilevel analyses. The results show that there is a positive impact of ethnic school composition on ethnic minority religiosity. This does not mean, however, that pupils become more religious in schools with a higher share of ethnic minority pupils. We rather see that a decline in religiosity among highly religious pupils is attenuated in schools with more ethnic minority pupils. 相似文献

Animals often aid others without gaining any immediate benefits. Although these acts seem to reduce the donor's fitness, they are only apparently altruistic. Donors typically help because they or their kin receive future benefits or avoid costly punishment. Reciprocal altruism--alternating the roles of donor and recipient--has been a well-studied form of cooperation among non-kin because of its intuitive appeal in explaining human cooperation. Despite immense theoretical interest, little empirical evidence substantiates the biological importance of reciprocal altruism in non-human animals. We propose that this is because psychological mechanisms constrain its application in cooperative contexts. In particular, we contend that cognitive limitations such as temporal discounting, numerical discrimination and memory make reciprocity difficult for animals. 相似文献

Background and Objectives: Distress intolerance (DI) has been identified as a potential risk factor for a variety of maladaptive avoidance behaviors, including worry. However, mechanisms linking DI to specific behaviors remain poorly understood. One hypothesis is that DI is a general vulnerability that confers risk of particular avoidance behaviors via more specific, lower-order vulnerabilities. The current study examined associations between DI and worry-related cognitions. Design: A multiple mediator model tested the hypothesis that worry-related variables (intolerance of uncertainty [IU], cognitive avoidance, beliefs about worry, and negative problem orientation) mediated the association between DI and worry. Methods: An undergraduate student (n = 281) and a clinical (n = 123) sample completed self-report measures. Results: Across samples, worry was associated with higher levels of DI, IU, cognitive avoidance, beliefs about worry, and negative problem orientation. Mediation results differed somewhat between the two samples. In the undergraduate sample, IU, negative beliefs about worry, and positive beliefs about worry mediated the association between DI and worry. In the clinical sample, negative problem orientation and negative beliefs about worry mediated the association between DI and worry. Conclusions: Results provide initial evidence that DI may be associated with worry via unique risk factors. 相似文献

In auditory warning design the idea of the strength of the association between sound and referent has been pivotal. Research has proceeded via constructing classification systems of signal-referent associations and then testing predictions about ease of learning of different levels of signal-referent relation strength across and within different types of auditory signal (viz., speech, abstract sounds, and auditory icons). However, progress is hampered by terminological confusions and by neglect of the cognitive contribution (viz., learning) of the person or user. Drawing upon semiotics and cognitive psychology, the authors highlight the indexical (as opposed to iconic) nature of so-called auditory icons, and the authors identify the cogniser as an indispensable element in the tripartite nature of signification. Classifications that neglect this third element, defining signal-referent relation strength only dyadically, yield results confounded by learning; classifications that correctly include the triadic relation yield research predictions that are redundant. These limitations of the standard method of constructing and testing classification systems suggest that auditory warning design must take the cognitive contribution of the user into account at an earlier stage in the design process. 相似文献

Sex and Punishment: An Examination of Sexual Consequences and the Sexual Double Standard in Teen Programming 总被引:1,自引:0,他引:1
A content analysis was conducted to examine sexual consequences on teen programming. The sample consisted of prime-time television dramas that featured characters between the ages of 12 and 22 years. Two major goals guided the study. First, the types of sexual consequences in teen programming were investigated. Results showed that emotional and social consequences far outnumbered physical consequences. Second, the portrayal of the sexual double standard was investigated. Negative consequences were more common in scenes in which female characters initiated sexual activities than in scenes in which male characters initiated sexual activities. Implications for future content analyses and media-effects research are discussed. 相似文献

This study evaluated the effectiveness of using a 5 s constant time delay (CTD) procedure to teach the written spelling of social studies vocabulary words taken from the general education social studies content to students with mild disabilities. Subjects were 3 elementary students with mild disabilities. Instruction was delivered in a small group setting. Vocabulary words were different for each student, which allowed for observational learning by the other students in the group. Assessments of observational learning were conducted when each student attempted to spell their group-mate's words. Related instructive feedback (meaningful sentences containing the social studies vocabulary words) was presented in the consequent event of instructional trials. A multiple probe design across word sets was implemented to evaluate the effectiveness of the procedure. Results indicated that (a) CTD was reliably implemented and all students acquired the spelling of their own sets of 12 social studies vocabulary words with 100% accuracy and maintained this accuracy over time, (b) all students generalized their target spellings across settings and instructors, and (c) some observational and instructive feedback learning occurred for all students. Additionally, long-term maintenance of observational spellings decreased over time, and minor fluctuations in long-term maintenance of instructive feedback occurred. 相似文献
