小学生创造性文学问题提出能力的发展研究   总被引:1,自引:1,他引:0       下载免费PDF全文
运用实验的方法,对来自山西两所小学371名小学生创造性文学问题提出能力的发展进行了研究。结果表明:(1)小学生创造性文学问题提出能力整体呈现持续上升的趋势;(2)男女生在创造性文学问题提出能力上存在差异,但差异不显著;(3)城市小学生整体优于乡村小学生的发展,二者的发展趋势同中有异;(4)小学四年级、五年级是小学生创造性文学问题提出能力的两个关键期。  相似文献

树立急救白金10分钟理念,提高社区猝死抢救成功率   总被引:1,自引:0,他引:1  
探讨建立社区急救体系提高猝死抢救成功率,比较国际与我国的急救现状、分析建立社区急救体系的保障因素、建立大众与社区急救流程、分析“急救白金十分钟”抢救的时效性规律。提出建立社区以家庭为个体急救单位、单元有志愿者、大楼设置救护小组、社区内建立自救站的大众急救网络;在其中组织多层面的大众急救宣传的培训;设置醒目的急救器械;设置社区内的急救流程。社区医院的建设需要政府的大力支持,要努力提高急救人员素质、建立长期培训和准入制度、高危人群筛查、建立对讲呼叫通讯网络、配备急足够的急救器材。最终建立和达到社会范畴的“急救白金十分钟”的时效性理想。  相似文献

幼儿认知灵活性的发展及其与言语能力的关系   总被引:1,自引:0,他引:1  
李红  王永芝 《心理科学》2006,29(6):1306-1311
认知灵活性是人类智力的一个重要特征,言语能力也是人类的一个关键能力,无论是个体灵活地使用语言,或者是语言在促进个体认知灵活性发展中的作用,都是不容低估的重要问题,但关于两者关系的研究却极其少见。以认知灵活性研究中经典的演绎范式DCCS任务和经典的归纳范式FIM、FIST任务为基础,从认知灵活性中对言语能力的探究、言语测验中包含的认知灵活性、以及两者共同的基础———表征能力等三个方面来阐明认知灵活性和言语发展之间的关系,最后表明了认知灵活性和言语能力之间的显著关系。  相似文献

延迟满足是一种心理成熟的表现,专指一种甘愿为更有价值的长远结果而放弃即时满足的抉择取向,以及在等待期中展示的自我控制能力。本文通过论述儿童的自我延迟满足能力的发展的特点以及影响其自我延迟满足能力的发展的因素,探索了如何教育儿童自我延迟满足能力的有效途径,对幼儿健康成长和发展具有一定的指导作用。  相似文献

By using a video‐based narrative (unidirectional) eyewitness statement of an alleged victim, participants were asked to imagine they were police officers. We compared the quality of mock police officer written records in a between‐subjects design comprising three conditions: (a) a free recall (n = 27), (b) a free recall by using recall strategies of the cognitive interview (n = 27), or (c) note taking while watching the video (n = 26). The quality of the reports was determined by the amount of correctly recalled details, omitted details, added details (commission errors), and changed details (confabulations). As predicted, the number of correct details was higher in the “Note Taking” condition whereas performance in the “Free Recall” and in the “Cognitive Interview” conditions did not differ. Higher verbal memory ability resulted in a better quality of the written records. Our results suggest that note taking facilitates the quality of written records.  相似文献

前瞻记忆意向后效应会对日常生活产生负面影响,研究发现这种现象在老年人中尤其突出。近些年来,研究者们从内外两方面对影响前瞻记忆意向后效应年龄差异的因素进行了探讨,了解到认知老化所带来的抑制能力的衰退以及短时记忆缺陷是造成其年龄差异的主要原因。未来研究需进一步拓展对认知老化的机制和抑制控制能力的认识。另外,可以采用事件相关电位(Event-Related Potentials, ERPs)和功能性磁共振成像(Functional Magnetic Resonance Imaging, fMRI)等脑成像技术揭示前瞻记忆意向后效应年龄差异的加工机制及神经机制。  相似文献

It has been argued that the high achievement of Confucian Asian students is at the cost of their psychological well‐being, since high self‐doubt consistently accompanies their high achievement. However, other researchers cautioned that the attitude toward self‐doubt could be different in Asian versus Western cultures. This study examined the debate with a survey of both American and Chinese college students that measured level of self‐doubt, attitude toward self‐doubt, beliefs about ability, and psychological well‐being outcomes. As hypothesized, Chinese students showed a more positive attitude toward self‐doubt than American students, despite having higher level of self‐doubt. Furthermore, self‐doubt engendered less negative consequences on Chinese students' psychological well‐being, relative to American students. Implications for theories and research on cultural differences in the effects of self‐constructs are discussed.  相似文献

选取语音意识和快速自动命名双重缺陷的汉语发展性阅读障碍儿童,探讨其言语工作记忆和阅读能力的发展特点。实验选取双重缺陷的发展性阅读障碍(DD)、年龄匹配(CA)和能力匹配(RL)三组儿童各25名,要求他们完成言语工作记忆(数字广度、汉字广度)和阅读(一分钟词汇阅读、三分钟句子阅读)任务。结果发现,DD儿童的数字倒背位数、一分钟读词数、三分钟读过字数和句子理解正确率均显著低于CA儿童,而与RL儿童差异不显著;DD儿童的句子阅读正确率显著低于CA、RL儿童。表明双重缺陷DD儿童在言语工作记忆和阅读能力上存在一定程度的发展滞后和缺陷。  相似文献

Poor decision-making and executive function deficits are frequently observed in individuals with substance use disorders (SUDs), and executive deficits may contribute to poor decision-making in this population. This study examined the influence of lifetime history of an alcohol, cocaine, heroin, or polysubstance use disorder on decision-making as measured by the Iowa Gambling Task (IGT) after controlling for executive ability, demographic characteristics, and current substance use. Participants (131 with lifetime history of SUD and 37 controls) completed the IGT and two neuropsychological tests: the Trail Making Test and the Controlled Oral Word Association Test. Control participants performed significantly better than those with a lifetime SUD history on the IGT, but performance on the neuropsychological tests was comparable for the two groups. A lifetime SUD diagnosis was associated with performance on the IGT after controlling for covariates, and Trail Making Test performance was associated with IGT performance in both SUD and control participants.  相似文献

Three experiments examined the effects of interactive visualizations and spatial abilities on a task requiring participants to infer and draw cross sections of a three-dimensional (3D) object. The experiments manipulated whether participants could interactively control a virtual 3D visualization of the object while performing the task, and compared participants who were allowed interactive control of the visualization to those who were not allowed control. In Experiment 1, interactivity produced better performance than passive viewing, but the advantage of interactivity disappeared in Experiment 2 when visual input for the two conditions in a yoked design was equalized. In Experiments 2 and 3, differences in how interactive participants manipulated the visualization were large and related to performance. In Experiment 3, non-interactive participants who watched optimal movements of the display performed as well as interactive participants who manipulated the visualization effectively and better than interactive participants who manipulated the visualization ineffectively. Spatial ability made an independent contribution to performance on the spatial reasoning task, but did not predict patterns of interactive behavior. These experiments indicate that providing participants with active control of a computer visualization does not necessarily enhance task performance, whereas seeing the most task-relevant information does, and this is true regardless of whether the task-relevant information is obtained actively or passively.  相似文献
