This study investigated the relation between Dual Language Learners’ (N = 90) vocabulary and grammar comprehension and word learning processes in preschool (aged 3-through-5 years). Of interest was whether: (a) performance in Spanish correlated with performance in English within each domain; and (b) comprehension predicted novel word learning within and across languages. Dual-language experience was evaluated as a potential moderator. Hierarchical linear modeling revealed stronger predictive associations within each language than across languages. Across languages, results varied by experience and domain. Structural sensitivity theory suggests exposure to two languages heightens awareness of parameters along which languages vary and provides a framework for interpreting complex associations within and across languages. Knowledge from one language may influence learning in both. 相似文献

Five experiments are reported in which rats were given CS-shock pairings and then permitted, in the absence of shock, to perform a hurdle-jump response that led to CS offset. In Experiment 1–4, the animals failed to learn the required response. Although several procedural variations were employed, the experimental groups continued to perform no better than backward-conditioned controls. In Experiment 5, some animals were punished for remaining immobile during a single trial at the start of hurdle-jump training. These animals performed significantly better than nonpunished controls and better than any group in Experiments 1–4. The results support the idea that the major role of the CS in escape-from-fear situations is to activate an innate motivational system which chooses between the species-specific defense reactions of freezing and fleeing. 相似文献

Many immigrant Hispanic women in the United States choose to bottle-feed rather than breastfeed. This article describes an intervention that was developed and tested in a two-step process. Two studies were undertaken. First, a qualitative inquiry explored the breastfeeding beliefs, attitudes, meanings, and practices of Hispanic women. Results informed the design of a culturally appropriate prenatal breastfeeding education intervention. Secondly, the researchers undertook a quantitative study of the intervention's success in increasing breastfeeding duration among Hispanic women. Methodology and findings of this study have implications for future interventions that promote breastfeeding. 相似文献

Are mathematics disabilities due to a domain-general or a domain-specific working memory deficit? 总被引:12,自引:0,他引:12
The relationship between verbal and visual-spatial working memory and mathematical computation skill was examined in children and adults with and without disabilities in mathematics. A hierarchical regression analysis showed that, when partialing for the influence of reading ability, age, and gender, mathematical computation was better predicted by verbal than by visual-spatial working memory. Furthermore, the results showed that the relationship between mathematics ability and working memory were not significantly moderated by age but were stable across a broad age span. We concluded that, regardless of age, deficits in mathematics are mediated by both a domain-general and a domain-specific working memory system. 相似文献

Parents and teachers reported that 6- to 8-year-old boys with developmental delays were less able to regulate their emotions than nondelayed boys matched on chronological age. Compared to nondelayed boys, boys with developmental delays had more social problems, which persisted and increased over a 3-year period. Children's ability to regulate their emotions explained significant variance in their social problems after controlling for their developmental status. In addition, emotion regulation partially mediated the relationship between children's developmental status and their social problems. These results suggest that emotion regulation plays a significant role in the social problems of boys with developmental delays. Furthermore, increasing the emotional competence of these children may facilitate their peer relationships and, ultimately, their school adjustment. 相似文献
