母语句法结构对中国学生英语语句理解的影响   总被引:2,自引:0,他引:2  
中国学生的英语学习受到汉语的影响,尽管这种影响随着学生英语提高而渐趋减小,但当学生的英语达到相当高水平时仍可较明显地观察到。通过实验证明:中国英语专业二年级学生在英语学习中仍受到汉语一定程度的影响,而且在词序方面尤为明显。这种影响的存在表明在中国的英语教学和学习中应给予母语因素以足够的重视。  相似文献

对听觉条件下中文字词劣效果的问题进行了实验考察,结果发现:在文章听点作业中,被试对高、低频目标字词语音的正误判断量存在着显著性差别,前者较后者成绩差,表现出字词劣效果的现象;在单字词的听点作业中,未发现被试对高、低频目标字词语音正误判断量方面的显著性差别;无论在文章还是单字词的听点作业中,被试对高、低频目标字词语音的正误判断量均比较低下,表明语音知觉的范畴性特征对字词语音的辩认准确性具有较大影响。  相似文献

The aim of this paper is to describe a study which investigated the influence of organizational factors on job involvement and specialization involvement. It was hypothesized that rank, self-expression, participation in decision making, and career factors affect job and specialization involvement. The independent variables were chosen by considering an extension of Schein's (1971, Journal of Applied Behavioral Science, 7, 401–426) “career cone” concept. The hypotheses were tested using a sample of Australian Army officers (N = 384) in a questionnaire survey. The results showed that job involvement is associated primarily with self-expression, although the latter is influenced in turn by participation in decision making, and that specialization involvement is associated with both self-expression and career factors. Rank does not affect either involvement variable. It was concluded that Schein's concept is a useful guide to theory and research on career attitudes. The results support the proposition that job and specialization involvement are distinct constructs. Implications for organizations are discussed.  相似文献

In this paper I formulate an approach for evaluating probabilistic forecasts in terms of signal detection theory. Signal detection theory provides a powerful perspective for this type of problem, and a rich empirical background including methodological tools as well as an extensive body of research in many domains. I propose procedures which emphasize the maximization of expected utility for the decision maker who uses the forecasts. Further, I suggest approaches to obtaining indices of calibration and resolution within this framework. I also present arguments that the proposed indices will exhibit the same basic properties as do decompositions of Brier's (1950, Monthly Weather Review, 78, 1–3) mean probability score. However, the properties may be reflected in different ways, and hence, the present methods may lead to different conclusions about forecasting ability. Finally, I argue that the use of an expected utility loss function makes this approach more appropriate for practical applications as well as for theoretical research than other procedures with more arbitrary loss functions.  相似文献

已有研究表明死亡凸显会抑制自我面孔和自我参照记忆加工的自我优势,可是死亡凸显对自我姓名的影响尚不明确,本研究采用事件相关电位技术,探索死亡凸显对自我姓名注意瞬脱对抗效应及其大脑神经活动的影响。58名被试在经历不同的启动任务后,完成自我姓名、朋友姓名和名人姓名的注意瞬脱任务。行为结果发现自我姓名识别正确率显著高于朋友姓名和名人姓名,表现出稳定的自我姓名加工的注意瞬脱对抗效应;电生理数据发现死亡启动后自我姓名诱发的P300波幅显著低于消极启动组和中性启动组,而朋友姓名和名人姓名并不受启动的影响。本研究结果与以往研究结果共同表明死亡想法凸显会使个体将抑制自我加工(自我姓名、自我面孔和自我参照记忆)作为应对远端死亡焦虑的一种手段。  相似文献

父母低头行为对儿童青少年心理发展的影响   总被引:1,自引:0,他引:1       下载免费PDF全文
父母低头行为是指父母照顾或与孩子交流时,过分关注与使用手机而忽视孩子的行为。梳理相关研究发现,父母低头行为会对孩子产生多种不良影响,如,降低亲子关系交流质量、增加意外伤害风险、损伤人际交往能力、导致问题行为增多。现有研究采用取代假说、多任务操作理论以及依恋理论对影响过程进行解释。未来研究的关键在于邻近概念的区分、测量方式和研究方法的改进、探讨儿童对父母手机使用行为的看法以及移动设备对亲子互动可能的积极影响。  相似文献

This research compared the retention of nouns, adjectives and verbs of sentences. A model of the structure underlying the retention of sentences and in which deep structure constituent propositions are hierarchically related, was used to make predictions concerning the retention of these word classes. The model was not supported by the data and it was determined that latencies to recognize the words of a previously presented sentence were the same for all classes of words. This result indicated that for recognition (but not necessarily for other memory tasks), each word of a sentence is seperately or equally accessible (as long as inter-word imagery is the same). However, a further experiment showed that, although word class is not a variable, the image-arousing capacity of a word is. Latencies and error rates were much lower for high-imagery words than for low-imagery ones. The findings on error rates in recognizing words were interesting and pointed to a different model where the meaning representations and syntatic functions of words have an active role in sentence retention.  相似文献

Nondepressed human subjects were divided into seven groups. On a series of discrimination problems, a helplessness group received insoluble problems, a solvable group received contingent feedback, and a no treatment control group received no feedback. For two other groups insoluble problems were preceded by success feedback on a different task presented according to a fixed ratio (FR) or variable ratio (VR) schedule of reinforcement. Two control groups received either FR or VR schedules of success but were not examined on the discrimination problems. All groups were tested for escape/avoidance performance on a human shuttle box. Both FR and VR schedules produced an inoculation against learned helplessness; escape performance by the helplessness group was significantly worse than that of FR and VR inoculation groups. These latter groups performed similar to the solvable and three control groups. Significantly worse than that of FR and VR inoculation groups. These latter groups performed similar to the solvable and three control groups. Significantly fewer subjects in the VR inoculation group exhibited avoidance responses than their counterparts in the FR inoculation group. despite similar escape performance. The findings indicate that learned helplessness can be prevented in humans and suggest different sources of interference produced by unpredictable and uncontrollable events.  相似文献
