The Louisville Twin Study: developmental synchronies in behavior 总被引:4,自引:0,他引:4
R S Wilson 《Child development》1983,54(2):298-316
The Louisville Twin Study includes nearly 500 pairs of twins and their siblings who have participated in a longitudinal study of mental development, beginning in infancy and extending to adolescence. The results show that individual differences beginning in infancy and extending to adolescence. The results show that individual differences in intelligence progressively stabilized by school age, and each child followed a distinctive pattern of spurts and lags in mental development. Monozygotic twins became increasingly concordant over ages and matched each other closely for developmental trends. By contrast, dizygotic twins regressed to an intermediate level of concordance, comparable with that found for siblings and parent-offspring sets. A comprehensive home assessment was performed to identify the home/family variables that contributed to mental development. The overall results pointed to a strong developmental thrust in the growth of intelligence, which was principally guided by an intrinsic genetic ground plan. Qualitative features of home and family did, however, add significantly to prediction of offspring IQ. The results are interpreted in the context of Waddington's developmental model, and some recent advances in neurobiology and genetics are surveyed for their implications for developmental behavior genetics. 相似文献

Parent or guardian perceptions play a specialized role in the evaluation of school teachers. Parents are important stakeholders
in teacher success, they are in some instances partners in the teachers' work, parents have unique personal information about
student learning, and they can report on the teacher duties to inform parents about the classroom and child progress. This
study analyzed the responses of parents to 12 survey items concerning teacher performance in 201 classrooms. The surveys were
used as part of an innovative teacher evaluation program in which teachers elected to include parent feedback as one objective
data source for annual review. In this study three factors emerged as important concerns for parents: humane treatment of
students, support for pupil learning, and effective communication and collaboration with parents. Recommendations for use
of specific survey items can be based on the empirical results of this sampling. The data gathered by parent surveys define
one dimension of quality which may vary in importance from one teacher to another. 相似文献

OBJECTIVES: The objectives of this work were to identify the sources of information currently received, information-seeking behaviours, information requirements and preferences for future information provision amongst health and social care professionals providing care to children with health care needs. METHODS: Data were collected using a cross-sectional postal questionnaire survey. RESULTS: A wide range of information resources was reported as being available to professionals. However, a large proportion of respondents found it necessary to perform additional searches for information, suggesting that current resources were not satisfying their needs. The majority of professionals reported a preference for electronic formats, whilst a smaller proportion preferred hard copy materials. Participants promoted the use of informal networks as a means of support and exchange of information. CONCLUSION: Supplementing the information that is provided in electronic and hard copy formats, by enhancing informal networks, may be the most effective way of meeting the information needs of this group of professionals. 相似文献

In two experiments, participants inspected and drank a series of drinks, half of which contained sugar and half unpalatable
Tween20 (tween). Each sugar and tween drink had a particular flavor and color. Following this training, the flavors of the
sugar drinks were assigned higher hedonic evaluations than were those of the tween drinks, even though the participants did
not reliably report which flavors had been present in the sugar and tween drinks during training. Moreover, the evaluative
conditioning of the flavors was unaffected by whether or not the colors alone had been pretrained to predict the presence
of sugar or tween in the drinks. In accord with Baeyens, Eelen, van den Bergh, and Crombez (1990), we conclude that flavor-evaluative
conditioning is not mediated by contingency learning. 相似文献

Infant joint attention has been observed to be related to social-emotional outcomes in at-risk children. To address whether this relation is also evident in typically developing children, 52 children were tested at 12, 15, 24, and 30 months to examine associations between infant joint attention and social outcomes. Twelve-month initiating and responding to joint attention were related to 30-month social competence and externalizing behavior, even when accounting for 15-month temperament ratings, 24-month cognition and language, and demographic variables. These results suggest that, in addition to associations with language and cognition, infant joint attention reflects robust aspects of development that are related to individual differences in the emergence of social and behavioral competence in childhood. 相似文献

This longitudinal study of 105 economically disadvantaged children examined the relation between reading problems and internalizing behavior in 3rd- and 5th-grade assessments (8- to 12-year olds). The variable-centered results showed that reading problems predicted change in internalizing behavior in the context of child and family predictors. The person-centered results showed that children with reading problems in both grades had higher internalizing scores in 5th grade but not in 3rd grade than children with reading problems in 3rd grade or no problems. Child-reported negative emotion experiences varied similarly across grade. The results tie reading problems to emotional distress in school and support conclusions about the direction of effects and the internalization of academic difficulty for disadvantaged children. 相似文献

Cumulative stress and substantiated maltreatment: the importance of caregiver vulnerability and adult partner violence 总被引:1,自引:0,他引:1
OBJECTIVE: Our goal is to assess the effect of caregiver vulnerabilities, singly and in combination, on the substantiation of child abuse (physical, sexual) and neglect, while controlling for relevant background variables. We test the moderator role of adult partner violence in qualifying the relationship between caregiver vulnerabilities and maltreatment substantiation. METHOD: Secondary analyses of the 1998 Canadian Incidence Study of Reported Child Maltreatment (CIS) are used to predict child protective service investigation substantiation versus non-substantiation from a range of caregiver vulnerability factors. Involvement in partner violence was examined as a moderator in the relation between caregiver vulnerabilities and maltreatment substantiation. The CIS is an epidemiological survey of first-reported cases to child protective services, using a random sample of child welfare agencies across Canada. Child welfare workers completed a research form on the child, primary caregiver, family, perpetrator, severity and type of maltreatment, as well as services and court outcomes. All maltreatment classifications were assigned according to the Canadian legal definition of child abuse and neglect. Hierarchical logistic regression analyses were used, with stepped entry of: (1) demographic factors, socioeconomic disadvantage, and caregiver's own history of maltreatment; (2) caregiver vulnerability factors; (3) involvement in partner violence; (4) the interaction between caregiver vulnerability and partner violence. RESULTS: Caregiver substance abuse was found to be the single most potent kind of caregiver vulnerability in predicting maltreatment substantiation. When the total number of vulnerabilities was used as the predictor, prediction across all types of maltreatment increased, especially for substantiated neglect. Analyses also showed that the presence of partner violence in the home exacerbated the effect of caregiver vulnerability on substantiation. CONCLUSIONS: The total number of caregiver vulnerabilities was the best predictor of the substantiation of child abuse and neglect. This relationship was moderated by the existence of partner violence: high caregiver vulnerability and high partner violence increased the likelihood of substantiation versus non-substantiation. These results suggest that caregiver issues should be considered in tandem with partner relationships. Among child welfare cases, caregiver vulnerability and partner violence are critical targets for child maltreatment prevention and early child protective services intervention. 相似文献

Teachers need to update their competence profiles for 21st century challenges. Teaching strategies need to change and so do the competences teachers need to develop so as to empower 21st‐century learners. The European Framework for the Digital Competence of Educators (DigCompEdu) represents a paradigmatic example of this endeavour, taking stock of these needs. Defining the requirements of education professionals by teacher competence frameworks can serve multiple purposes at different levels in education systems. At the micro level, it can support and guide teachers' practice and continuous professional development. At the meso level of local education governance, it can support the development of school institutions as learning organisations, providing common ground for dialogue, collaboration and reflection in professional communities of practice. At the macro level of quality assurance, it can provide reference standards for initial teacher education, and for education professionals' quality along the career continuum. The European Framework for the Digital Competence of Educators was designed to align with institutional and contextual requirements in different countries, whilst remaining open to adaptation and updating. It links teachers' and students' digital competence development, and can be linked to institutional capacity building. At the same time, the framework is generic enough to apply to different educational settings and to allow for adaptation as technological possibilities and constraints evolve. 相似文献
