The hypothesis that language plays a role in theory-of-mind (ToM) development is supported by a number of lines of evidence (e.g., H. Lohmann & M. Tomasello, 2003). The current study sought to further investigate the relations between maternal language input, memory for false sentential complements, cognitive flexibility, and the development of explicit false belief understanding in 91 English-speaking typically developing children (M age = 61.3 months) and 30 children with specific language impairment (M age = 63.0 months). Concurrent and longitudinal findings converge in supporting a model in which maternal language input predicts the child's memory for false complements, which predicts cognitive flexibility, which in turn predicts explicit false belief understanding. 相似文献

Inter-day training reliability and variability in artistic gymnastics vaulting was determined using a customised infra-red timing gate and contact mat timing system. Thirteen Australian high performance gymnasts (eight males and five females) aged 11–23 years were assessed during two consecutive days of normal training. Each gymnast completed a number of vault repetitions per daily session. Inter-day variability of vault run-up velocities (at ‐18 to ‐12 m, ‐12 to ‐6 m, ‐6 to ‐2 m, and ‐2 to 0 m from the nearest edge of the beat board), and board contact, pre-flight, and table contact times were determined using mixed modelling statistics to account for random (within-subject variability) and fixed effects (gender, number of subjects, number of trials). The difference in the mean (Mdiff) and Cohen's effect sizes for reliability assessment and intra-class correlation coefficients, and the coefficient of variation percentage (CV%) were calculated for variability assessment. Approach velocity (‐18 to ‐2 m, CV = 2.4–7.8%) and board contact time (CV = 3.5%) were less variable measures when accounting for day-to-day performance differences, than pre-flight time (CV = 17.7%) and table contact time (CV = 20.5%). While pre-flight and table contact times are relevant training measures, approach velocity and board contact time are more reliable when quantifying vaulting performance. 相似文献

Hi Brad,
I plan to find a part-time job.I've already passed the first three rounds of interviews of an education institution and attended a fiveday training program for a part-time English teacher for junior school students,one on one.With another two rounds of interviews and real teaching activities ahead,I'm not fully prepared and confident enough since I never have teaching experience before.
I remember you mentioned that you are tutoring English to foreign students.Could you please provide some useful suggestions? 相似文献

Dear Brad,
I have finished the examination.While waiting for the result to come,I want to ask for some suggestion from you on how to spend this vacation to make it a meaningful time and prepare myself for the future life.
Best Wishes,
Silvia
Hi Silvia,
Congratulations on having completed the examination.I know it is a very stressful time for students.I'm sure you're glad it's over and now you can relax for a while. 相似文献

Dear Brad,
I will study abroad in the middle of July,in Toronto,Canada.I want to ask you something about the luggage pack.Although I have searched the Intemet,there are many different versions.Could you give me some advice about packing?
Besides,I am really nervous since I am afraid that I can't catch the lesson and may have no friends there.I hope people around me are all kind and helpful like you! 相似文献

Health policy experts long have argued that a combination of budgetary constraints, lack of legislative expertise, and parochial attitudes make it unlikely that the U.S. states will contribute significantly to health care reform. This is particularly true of states like Texas, which ranks last or near-to-last in virtually every measure of public health, and is dominated by conservative politics and libertarian, free market ideology. Yet, in 1997 the Texas legislature enacted the first Patient's Bill of Rights. This article examines the political and rhetorical processes that led to successful reform, and discusses the implications that success in "the least likely place" holds for the making of health care policy. 相似文献

Beverage-agarose gel electrophoresis: an inquiry-based laboratory exercise with virtual adaptation 总被引:1,自引:1,他引:0
A wide range of literature and experience has shown that teaching methods that promote active learning, such as inquiry-based approaches, are more effective than those that rely on passive learning. Gel electrophoresis, one of the most common laboratory techniques in molecular biology, has a wide range of applications in the life sciences. As such, we chose it as a platform to expose high school and undergraduate students to the active process of scientific inquiry in general, while specifically teaching electrophoresis. First, we optimized DNA electrophoresis in the laboratory by using common beverages instead of standard media (e.g., Tris-based media). Second, we adapted this laboratory process of progressive optimization to a Web-based format in which students had to achieve all the same steps of optimization by performing serial electrophoreses. And third, we evaluated the use of this entirely Web-based virtual laboratory exercise in high school and undergraduate biology courses. Students learned fundamental and practical principles of electrophoresis, while experiencing the essential inquiry-based process of optimizing a technique, and they also enjoyed it. Our findings provide a readily accessible, inexpensive, and intriguing technique for teaching electrophoresis and the progressive optimization of a laboratory technique. 相似文献

African-American youth suffer disproportionately from sexual risk consequences including unintended pregnancy and sexually transmitted infections. Parents educating young people about sex may be one approach to reduce sexual risk behaviour among this population. The purpose of this study was to determine young people's perceptions of parents' attitudes about sex and assess whether these perceptions affect sexual risk. Data were collected from 560 African-Americans, aged 9–19 years. Most (73.4%) thought their parents would be unhappy if they got someone pregnant/got pregnant, with more girls feeling this way than boys (p = 0.013). Sexually active boys who thought their parents would be unhappy if they got someone pregnant reported fewer sexual partners within the past year (p < 0.01) and fewer sexual encounters in the past 3 months (p = 0.01) compared to those whose parents would think otherwise. Our research illustrates that parents' explicit and unstated attitudes are apparent to their offspring, and young people's perceptions can impact their risk behaviour. As such, early and often sex education communication between parents and young people should be encouraged. Sexual health interventions encouraging parents to educate about sex and its consequences could enhance the health of young African-Americans. 相似文献
