Generic noun phrases (e.g., "Bats live in caves") are important for expressing knowledge about abstract kinds. Past work has found that parents frequently use generic noun phrases in their speech to young children. However, little is known regarding how children understand these expressions, nor which cues signal generic meaning. The present set of 5 studies examined the influence of linguistic form class (e.g., "What color are dogs?" [generic] versus "What color are the dogs?" [nongeneric]) and of pragmatic context (e.g., "What color are they?" in the presence of either a single exemplar [generic] or multiple exemplars [nongeneric]). Participants were 2-year-olds (N = 42), 3-year-olds (N = 40), 4-year-olds (N = 40), and adults (N = 51). The data indicate that by 2 years of age, children use linguistic form class, and by 3 years of age, children use pragmatic context. These findings demonstrate that young children have begun to understand the distinction between generic and nongeneric noun phrases from a very young age, and that identification of generics is signaled not by formal or pragmatic cues alone, but by a combination of information from both language form and pragmatic context. It is suggested that children make use of multiple linguistic and conceptual cues to acquire and interpret generics. 相似文献

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition. 相似文献

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children. 相似文献

The dramatic growth in the number of children learning English as a second language in our country has led to a corresponding
increase in the need to understand how teachers and schools can effectively teach children who are learning English as a second
language. Many teachers report not feeling prepared to meet the needs of these children (National Center for Education Statistics,
Teacher preparation and professional development: 2000. , 2002). The current study used focus group interviews to examine how Head Start teachers in one program addressed the special learning
needs of children learning English in their classrooms. Key challenges involved communicating with children and their families
in their home language. Teachers used other staff, parents, and children in the classroom to interpret. Strategies involved
visual aids, pictures, gestures, and a welcoming classroom environment. Resources used by teachers were professional development
and language skills of other staff. However, available resources were often underutilized and limited for teachers to use
in meeting the challenges the teachers faced in the classroom. Suggestions are presented for overcoming the challenges and
limited resources encountered by teachers, such as changes in preservice and inservice training opportunities, and second
language learning opportunities for teachers. Further implications for training and research are discussed. 相似文献

The purpose of this study was to examine: (a) the role of teacher talk in promoting peer interaction, (b) the adequacy of
social IEP objectives to reflect children’s social functioning and guide provision of teacher talk, and (c) differences in
children’s peer interaction and teacher talk in inclusive and segregated settings. Thirty children with disabilities and their
teachers participated. Overall, we observed low rates of teacher talk thought to support peer interaction; however, when teachers
verbally facilitated peer interaction, children were observed interacting more frequently with peers. Children’s social IEPs
accurately reflected their current level of social functioning. However, the social IEPs appeared to fail to influence teacher
intervention. Finally, children with disabilities in inclusive settings interacted with peers more than children in segregated
settings, even though there was no significant difference in amount of teacher talk in the two settings. 相似文献

ABSTRACTTo what extent does soccer increase the capability of the homeless and those living on the street? This study addresses this question by focusing on the ways in which the Homeless World Cup and Street Soccer (Scotland) have impacted upon the lives of some individuals. Primary source data obtained from a series of interviews are situated within Sen’s capability approach to social choice theory. The implications of the study contribute to policy by supporting the idea that sport can contribute as a resource of hope through the development of capability that impacts upon life chances and choices. It adds to a growing number of applied studies of sport that have critically used the work of Sen and it advances the way in which this body of work has been utilized in sport and related areas. 相似文献

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic. 相似文献
