Incidental teaching of language in the preschool 总被引:1,自引:0,他引:1
"Incidental teaching" denotes a process whereby language skills of labelling and describing are learned in naturally occurring adult-child interactions. In the present study, 15-min daily samples of the spontaneous speech of 11 children were recorded during free play over eight months of preschool. After incidental teaching of compound sentences, increases in unprompted use of compound sentences were seen for all the children, first directed to teachers, and then to children, in accordance with who attended to the children's requests for play materials. The incidental teaching procedure also stimulated spontaneous variety in speech, and appears to have general applicability to child learning settings. 相似文献

Six women and six men reproduced ten time intervals varying in logarithmic steps between 1.3 and 20 s. The durations were indicated by white noise of 10, 25, 40 and 55 dB SL, different sound intensities in different sessions. It was found that (i) greater sound intensity entails shorter reproductions, and (ii) reproductions by male observers are shorter than those by female, although for both (i) and (ii) there is an interaction with the standard durations. The data were treated in accordance with the "parallel-clock model" (Eisler, 1975), whereby the parameters of the psychophysical power function are determined from duration reproduction data. As in previous experiments (Eisler, 1975), the data showed a break in the function entailing two segments. The effect of sound intensity could be attributed to the exponent, which was lower for stronger noise, and the effect of sex to the weight coefficient of the upper relative to the lower segment of the psychophysical function, the coefficient being lower for men. 相似文献

我国自古便有“通过强调时间流逝而珍惜当下”的教育与文化传统,对这一“时间认知影响时间行为”的作用机理,当前所知不多。采用问卷法对2232名低年级大学生调查,以考察同一性状态、生命时间流逝情绪、流逝注意与时间管理之间的关系.结果显示:(1)同一性获得、延缓状态正向直接预测时间管理倾向各维度(时间价值感、监控观与效能感);早闭状态直接正向预测时间监控观、负向预测效能感;扩散状态直接负向预测时间价值感和监控观;(2)获得状态通过流逝情绪间接预测监控观和效能感;(3)延缓状态通过流逝情绪、流逝注意间接预测监控观、效能感,还能通过流逝注意间接预测价值感;(4)早闭状态通过流逝注意间接预测时间管理各维度,其中,流逝注意在“早闭—价值”间起完全中介作用。 相似文献

Mathematical giftedness refers to mastery in a specific mathematical domain at an earlier than expected age. The present study examined which cognitive processes accounted for differences in mathematical reasoning between gifted children (MRG) and their typically achieving peers (TA). Naming speed, phonological awareness, short-term memory, executive functioning, and working memory were examined in 51 children aged approximately 7 years. A series of stepwise regression models, using a contrast variable to capture differences in mathematical reasoning between MRG and TA children, were created to examine which cognitive domains accounted for differences in mathematical reasoning. Short-term memory (r2?=?.08) and visual-spatial working memory (r2?=?.39) emerged as the only cognitive predictors within a model that included gender, age, and fluid intelligence. This model captured all of the variance distinguishing mathematics reasoning between MRG and TA children, explaining an overall contribution of 70% of the variance in mathematical reasoning. 相似文献

Previous studies have indicated that “need for cognition” (NfC), which is the tendency to enjoy effortful cognitive activity, affects various cognitive processes and behaviors. However, the effects of NfC on mental adaptation have not been investigated. According to previous studies, it can be hypothesized that NfC decreases maladaptive self‐focusing, which is called self‐rumination, through increasing effortful control (EC); therefore, we hypothesized that NfC would indirectly inhibit self‐rumination through the mediation of EC. As we expected, the results of a cross‐sectional questionnaire study with 152 undergraduate participants indicated a negative indirect association between NfC and self‐rumination through the mediation of EC. Secondarily, the present results revealed a direct positive association between NfC and adaptive type of self‐focusing, which is called self‐reflection. The present study is the first to propose the possible contribution of NfC to mental health through decreasing self‐rumination and increasing self‐reflection. 相似文献

It has been argued, by Penrose and others, that Gödel's proof of his first incompleteness theorem shows that human mathematics cannot be captured by a formal system F: the Gödel sentence G(F) of F can be proved by a (human) mathematician but is not provable in F. To this argment it has been objected that the mathematician can prove G(F) only if (s)he can prove that F is consistent, which is unlikely if F is complicated. Penrose has invented a new argument intended to avoid this objection. In the paper I try to show that Penrose's new argument is inconclusive. 相似文献

初中数学学习中教师归因与学生自我归因的比较研究 总被引:14,自引:2,他引:12
本文研究了初中数学学习中教师的信念与归因.学生自我的信念与归因以及师生归因的比较,得出如下几点结论:(1)在教师和学生的信念中男生在数学学习中更占优势。但在归因领域里却没有发现显著的性别差异。(2)对最好的学生,教师倾向于努力归因;对最差的学生,教师倾向于基础归囚。(3)最好的学生自我归因时倾向于基础和方法归因,最差的学生倾向于努力和方法归因。(4)师生归因维度上的一般趋势:造成数学学习成功的原因比较稳定、内源、可控;造成数学学习失败的原因也倾向于内源,但比较不稳定,不可控。(5)师生特定归因中的差异广泛存在,建议采取相应的教育对策。 相似文献

医疗费用的水准及其变化过程主要取决于一个国家的经济发展水平。我们预测其变化趋势可能经历三个新阶段。因此,在宏观管理上要注意四个方面的政策取向:重效率轻收入、重效果轻价格、重科学管理轻粗放经营、重长远利益轻眼前利益。 相似文献

摘 要 以高低强迫倾向个体为研究对象,考察其在不同概率情景设置的Flanker任务中的信息加工灵活性,研究结果表明:高强迫倾向个体的信息加工方式相对较缓慢、单一,以集中加工方式为主;高强迫倾向个体对情境的变化较少做出反应,在信息加工的灵活性上存在缺陷,而低倾向个体的信息加工方式相对较灵活;高强迫倾向个体不易受线索提示的影响,对信息加工方式的策略性调控能力不足。 相似文献
