Research suggests that non-linguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a three-location spatiotemporal sequence of multi-colored geometric shapes. Early language skills were assessed using the MacArthur-Bates CDI. Analyses of children's reaction times to the stimuli suggest that the extent to which infants demonstrated learning was significantly correlated with their vocabulary comprehension at the time of test and with their gestural comprehension abilities 5 months later. These findings suggest that visual sequence learning may have both domain-general and domain-specific associations with language learning. 相似文献

The child welfare system indicates that evidence of successful completion of parenting classes is instrumental in determining whether parents are actively engaged in the process of permanency planning. Such classes vary in length and intensity with topics ranging from "How to Raise Healthy Families" to "How to Discipline Your Child." Two social workers (one white and one black), who initially disagreed about the format of a parenting class, chronicle their efforts to collaborate and create a class format that recognizes the psychosocial and, more specifically, the cultural influences inherent in facilitating these classes. The juxtaposition of the clinical concepts of projection and projective identification are evaluated against the backdrop of the social concepts of empowerment and diversity. 相似文献

American ecologists recently began to address the ecology of cities. Concurrently, higher education institutions have developed sustainability education programs and instituted sustainability policies and projects. This paper draws together these two disparate areas by examining the nitrogen (N) budget of the Twin Cities campus of the University of Minnesota. We addressed the question: what were the annual inputs, outputs and internal cycles of N on the University of Minnesota Twin Cities campus? We found that 508 Mg N yr-1 were brought into the campus and 494 Mg N yr-1 were emitted from the University of Minnesota campus. The largest N inputs were abiotic fixation (conversion of N2 to NOx by combustion) and food for humans and animals. The largest N output was NOx, followed by wastewater. Our results expand the understanding of the ecology of institutions within an urban area and provide an opportunity for improving urban ecology education and environmental policy at educational institutions. 相似文献

Confidence intervals for parameters of distributions with discrete sample spaces will be less conservative (i.e. have smaller coverage probabilities that are closer to the nominal level) when defined by inverting a test that does not require equal probability in each tail. However, the P‐value obtained from such tests can exhibit undesirable properties, which in turn result in undesirable properties in the associated confidence intervals. We illustrate these difficulties using P‐values for binomial proportions and the difference between binomial proportions. 相似文献

One is Not Enough: Multiple Exemplars Facilitate Infants' Generalizations of Novel Properties 下载免费PDF全文
Across three experiments, we examined 9‐ and 11‐month‐olds' mappings of novel sound properties to novel animal categories. Infants were familiarized with novel animal–novel sound pairings (e.g., Animal A [red]–Sound 1) and then tested on: (1) their acquisition of the original pairing and (2) their generalization of the sound property to a new member of a familiarized category (e.g., Animal A [blue]–Sound 1). When familiarized with a single exemplar of a category, 11‐month‐olds showed no evidence of acquiring or generalizing the animal–sound pairings. In contrast, 11‐month‐olds learnt the original animal–sound mappings and generalized the sound property to a novel member of that category when familiarized with multiple exemplars of a category. Finally, when familiarized with multiple exemplars, 9‐month‐old infants learnt the original animal–sound pairing, but did not extend the novel sound property. The results of these experiments provide evidence for developmental differences in the facilitative role of multiple exemplars in promoting the learning and generalization of information. 相似文献

Researchers Behind Policy Development: Comparing ‘Age-Friendly Cities’ Models in Quebec and Wallonia
Based on a reflexive method, this article explores the roles of researchers behind Age-Friendly Cities and Environments. Referring to Michael Burawoy's division of sociological work (professional, critical, policy and public sociology), it is structured around the international comparison of two empirical case studies: Walloon region (Belgium) and Quebec (a province of Canada). While the first case shows some difficulties faced by a limited policy sociology perspective with little room for research, the latter presents a more developed public sociology approach with larger involvement from research. If both cases started with policy links, the latter presents a special interest for praxis, through knowledge transfer as an ongoing public dialogue. Based on this comparison, the article concludes with a twofold use of praxis: on one side – knowledge in action – a public sociology position offers an original perspective on what AFC/AFE may mean and produce to avoid a limited field of actions focusing only on some stakeholders or advocates for older people. On the other side – action in knowledge – policy and public sociology question professional and critical sociology facing AFC/AFE programmes: is a purely academic knowledge of such a programme epistemologically realistic or should it necessarily be empirically fuelled? 相似文献
