Predicting individual differences in attention, memory, and planning in first graders from experiences at home, child care, and school 总被引:1,自引:0,他引:1
NICHD Early Child Care Research Network 《Developmental psychology》2005,41(1):99-114
This study adds to the growing literature linking children's experiences in the environment to individual differences in their developing skills in attention, memory, and planning. The authors asked about the extent to which stimulating and sensitive care in the family and in the child-care or school environments would predict these cognitive outcomes. The authors also questioned the primacy of experiences in the first 3 years of life. Data from a sample of 700 first graders whose experiences in the home and in child care or school were evaluated since early infancy revealed that the cumulative quality of the child-rearing environment was related to attention and memory but not to planning and that the quality of the family environment was more strongly associated with outcomes than was the quality of child care and of school. The quality of both children's early (6 through 36 months) and later (54 months and first grade) environments predicted performance on the attention and memory tasks. 相似文献

This study examined whether the link between risk factors for conduct problems and low rates of participation in mental health
treatment could be decoupled through the provision of integrated prevention services in multiple easily-accessible contexts.
It included 445 families of first-grade children (55% minority), living in four diverse communities, and selected for early
signs of conduct problems. Results indicated that, under the right circumstances, these children and families could be enticed
to participate at high rates in school-based services, therapeutic groups, and home visits. Because different sets of risk
factors were related to different profiles of participation across the components of the prevention program, findings highlight
the need to offer services in multiple contexts to reach all children and families who might benefit from them.

儒学是人类中心主义吗? 总被引:4,自引:0,他引:4
儒学主张“以人为中心”,是指以人的问题为中心,解决人与自然的关系问题,不是以人的利益为中心,主宰、掠夺自然的人类中心主义。儒学提倡以人与自然和谐统一为特征的德性主体,不是提倡以人与自然分离、对立为特征的认识和价值主体。儒学承认自然界的内在价值,同情、尊重一切生命的生存与权利,以“万物一体”为最高追求。 相似文献

分析中国伪生命科学产生的文化原因和背景,指出其致命的谎言、骗术与危害;揭露其理论上的荒谬与科学上的无知。并强调开展对这类伪科学产品进行批判运动的意义;同时重新对科学、非科学、伪科学、宗教、神话、迷信等进行划界和定义。医学研究需要正义、需要哲学的引导;在事实的世界之上,必须由价值和意义的世界来把握;医学理论不允许任意杜撰和加工,从这个意义上,医学科学还需要法律来维护其正义 相似文献

The recent H1N1 pandemic influenza stimulated numerous studies into the attitudes and intentions about the H1N1 vaccine. However, no study has investigated prospective predictors of vaccination behaviour. We conducted a two-wave longitudinal study among residents in four U.S. cities during the course of the H1N1 outbreak, using Internet surveys to assess demographic, cognitive and emotional predictors of H1N1 vaccination behaviour. Surveys were conducted at two time points, before (Time 1) and after (Time 2) the H1N1 vaccine was widely available to the public. Results show that Time 2 vaccination rates, but not Time 1 vaccination intentions, tracked H1N1 prevalence across the four cities. Receipt of seasonal influenza vaccine in the previous year, worry, compliance with recommended interventions, household size and education assessed at Time 1 were significant prospective predictors of vaccination behaviour. Perception of the H1N1 vaccine, social influence and prioritised vaccine recipient status assessed at Time 2 also predicted vaccination behaviour. Critically, worry about H1N1 mediated the effects of both objective risk (prevalence at the city level) and perceived risk on vaccination behaviour. These results suggest that H1N1 vaccination behaviour appropriately reflected objective risk across regions, and worry acted as the mechanism by which vaccination behaviour followed objective risk. 相似文献
