先前研究发现远距离规则能够被内隐地习得和迁移,表明内隐学习获得的知识是底层的抽象规则,那么这一抽象规则的习得和迁移是否会受到先前知识经验的限制?研究采用汉语声调的远距离水平映射规则为材料,通过创设不符合平仄知识经验的任意声调水平映射规则,在控制组块和重复结构等表面特征的条件下,探讨先前知识经验是否限制了远距离水平映射规则的内隐学习和迁移。结果发现相对于符合平仄知识经验的汉语声调水平映射规则,被试不能够内隐地习得和迁移任意声调的水平映射规则,表明先前知识经验在远距离水平映射规则内隐学习过程中发挥着重要作用。  相似文献

Our contribution aims to verify whether parental knowledge about child development and parenting constitutes a protective factor in the application of dysfunctional educational practices. Numerous studies have found that parental knowledge has a great influence on parenting, however it remains unclear whether both are casually linked in a direct and linear way. Data currently available on parental knowledge almost exclusively refers to mothers and subjects at risk. Furthermore, there are almost no studies which take into consideration subjects who are Italian citizens.In contrast our work takes into consideration a normative sample of 157 Italian couples who are the parents of children aged between 16 and 36 months and who completed the Knowledge of Infant Development Inventory (KIDI; MacPhee, 1981) and the Parenting Scale (Arnold, O’Leary, Wolff, & Acker, 1993). The results highlight differences between mothers and fathers, both in terms of knowledge levels (higher for mothers) and educational practices (maternal practices are more frequently dysfunctional); knowledge influences educational practices above all in the case of fathers, although said effect is slight, which supports the idea that interaction between knowledge and parental practices is not linear but rather mediated by other factors.  相似文献

内隐学习领域关注的重要问题是被试能够习得何种结构及其相应的学习机制。远距离规则的研究为澄清这一问题提供了新的视角。现有研究已证实被试能够内隐地习得并迁移固定长度的远距离规则。按照内隐学习抽象性的观点,如果被试习得的是远距离的抽象规则本身,那么迁移也同时会发生在不同长度的材料上。因此,研究以独特的汉语声调水平映射规则为材料,通过对表面特征与底层规则之间的分离操作,探讨声调水平映射规则的内隐习得和长度迁移,结果表明被试不仅能够习得这一规则,还能够将该规则灵活迁移到不同长度的材料上,进一步为内隐学习的抽象性特点和无限性的学习机制提供强有力的新证据。  相似文献

A pplications of standard item response theory models assume local independence of items and persons. This paper presents polytomous multilevel testlet models for dual dependence due to item and person clustering in testlet‐based assessments with clustered samples. Simulation and survey data were analysed with a multilevel partial credit testlet model. This model was compared with three alternative models – a testlet partial credit model (PCM), multilevel PCM, and PCM – in terms of model parameter estimation. The results indicated that the deviance information criterion was the fit index that always correctly identified the true multilevel testlet model based on the quantified evidence in model selection, while the Akaike and Bayesian information criteria could not identify the true model. In general, the estimation model and the magnitude of item and person clustering impacted the estimation accuracy of ability parameters, while only the estimation model and the magnitude of item clustering affected the item parameter estimation accuracy. Furthermore, ignoring item clustering effects produced higher total errors in item parameter estimates but did not have much impact on the accuracy of ability parameter estimates, while ignoring person clustering effects yielded higher total errors in ability parameter estimates but did not have much effect on the accuracy of item parameter estimates. When both clustering effects were ignored in the PCM, item and ability parameter estimation accuracy was reduced.  相似文献

探索手术治疗单一局部复发或唯一远处转移病灶乳腺癌的临床价值。收集2006年6月至2013年6月湖南省人民医院乳甲外科收治的64例局部复发或术后远处转移乳腺癌患者,其中28例为单发病灶病例。根据是否采取了包含手术的综合治疗,将其分为手术组与非手术组。回顾性分析两组的临床资料和随访数据,分析手术治疗局部复发或远处转移乳腺癌有无临床意义。结果28例都采取了含化疗的综合治疗,8例局部单发病灶与9例远处单一脏器转移病例进行了手术治疗。手术组的局部缓解率与控制率明显优于非手术组,均为100%。两组无进展生存时间(PFS)和总生存时间(()S)比较,手术组明显长于非手术组;但在单一远处脏器转移手术组中0S没有优势。2年生存率方面手术组与非手术组比较有统计学意义。对于术后单一局部复发病灶或唯一远处脏器转移的乳腺癌患者,采取含手术的综合治疗方案能带来明显的PFS优势,若有手术机会和条件成熟,手术仍是不应放弃的有效治疗方法。  相似文献

The author's personal journey in discovering, developing, researching and practicing adult theological education in the church is rehearsed, pointing out key learning moments along the way. Out of this praxis seven theses are offered that set an agenda for theological education in the new missional era in which the church finds itself.  相似文献

By regarding the latent random vectors as hypothetical missing data and based on the conditional expectation of the complete-data log-likelihood function in the EM algorithm, we investigate assessment of local influence of various perturbation schemes in a nonlinear structural equation model. The basic building blocks of local influence analysis are computed via observations of the latent variables generated by the Metropolis-Hastings algorithm, while the diagnostic measures are obtained via the conformal normal curvature. Seven perturbation schemes, including some perturbation schemes on latent vectors, are investigated. The proposed procedure is illustrated by a simulation study and a real example. Acknowledgment: This research is fully supported by a grant (CUHK 4243/02H) from the Research Grant Council of the Hong Kong Special Administration Region. The authors are indebted to ICPSR and the relevant funding agency for allowing use of their data, and to the Editor and reviewers for their valuable comments for improving the paper.  相似文献

This paper reports on a micro‐qualitative case study of peoples' experiences of local community life in a south‐east English town. This material is used as the basis for a critical discussion of the suitability of Putnam's notion of social capital as a conceptual tool for the design and evaluation of ‘community strengthening’ policies and interventions. The study was motivated by a concern that too much debate about social capital has been conducted by academics and policy‐makers in a top‐down manner, with inadequate attention to the realities of life in the local communities that they refer to. Three‐hour semi‐structured interviews were conducted with 37 residents in two less affluent wards in our town of interest. Informants—half men and half women, and spread across the 15–75 age group—were encouraged to talk about their personal experiences of local community life. Interview findings are presented within the ‘norm’ categories of trust, neighbourliness and reciprocal help and support, and the ‘network’ categories of participation in informal networks, voluntary groupings and community activist groupings. Our case study points to a number of ways in which Putnam's concept needs to be refined if it is to inform ‘community strengthening’ policies and interventions in England. Far more notice needs to be taken of the role played by informal networks of friends and neighbours in the construction of local community life. Attention also needs to be given to the complex and shifting geographical spread of peoples' significant social networks. Putnam's conceptualization of cohesive local communities and his unitary notions of trust and local identity may also be unduly essentialist. In our particular communities of interest, they failed to capture the fluidity of local community norms and networks in a rapidly changing society. They also failed to do justice to the extent to which social distinctions—such as age, gender, ethnicity and housing tenure—shape and constrain the way in which people create, sustain and access social capital.
