幼儿口头言语发展的调查研究 1.幼儿简单陈述句句法结构发展的初步分析

前 言 言语发展是心理发展的重要组成部分,而汉语的组织体系和结构又不同于其他语言,研究我国儿童言语发展的特点和规律,对指导幼儿语言教学实践和探讨语言发展理论问题都具有极为重要的意义。然而,我国在这方面做的工作还很少,因此,我们于1978年以幼儿口语中句法结构的发展为重点进行了初步调查。本文是调查报告之一,只就幼儿言语     

结果冲突与作业难度对双重作业绩效的影响

运用单作业和双作业操作探讨结果冲突与作业难度对双重作业绩效的影响。结果表明：（１）信息干扰对双作业操作有着明显的影响。信息干扰越大,结果冲突效应越大,双作业操作绩效越差。（２）作业难度对双作业绩效有明显影响。作业难度越大,双作业操作绩效越差。根据实验结果,本研究提出了双因素假设：信息干扰和资源竞争是影响双作业操作绩效的两个主要因素。

The Relationship Between Happiness and Consumption Expenditure: Evidence from Rural China

We use data from the 2016 China Labor-force Dynamics Survey (CLDS) to examine the relationship between happiness and consumption expenditure of rural farmers in China. A two-stage residual inclusion approach is applied to tackle the potential endogeneity issue of happiness. The empirical results show that a higher level of happiness is associated with an increase in consumption expenditure in general. Further analysis reveals that higher levels of happiness are positively and significantly associated with higher expenditures on basic living goods, education and gifts. We also find that both household income and access to the Internet boost happiness and increase consumption expenditure. Happiness plays a larger role in improving the consumption expenditure of rural households compared with their urban counterparts. Our findings may suggest that improving rural income via income diversification strategies and investing in rural information and communication technology infrastructures would encourage rural farmers’ happiness, promote the upgrading of rural consumption and boost sustainable economic growth.

Varsity medical ethics debate 2018: constant health monitoring - the advance of technology into healthcare

The 2018 Varsity Medical Ethics debate convened upon the motion: “This house believes that the constant monitoring of our health does more harm than good”. This annual debate between students from the Universities of Oxford and Cambridge is now in its tenth year. This year’s debate was hosted at the Oxford Union on 8th of February 2018, with Oxford winning for the Opposition, and was the catalyst for the collation and expansion of ideas in this paper.New technological devices have the potential to enhance patient autonomy, improve patient safety, simplify the management of chronic diseases, increase connectivity between patients and healthcare professionals and assist individuals to make lifestyle changes to improve their health. However, these are pitted against an encroachment of technology medicalising the individual and home, an exacerbation of health inequalities, a risk to the security of patient data, an alteration of the doctor-patient relationship dynamic and an infringement on individual self-identity. This paper will draw upon and develop these concepts, while contending arguments for and against constant health monitoring. This is not a review of medical devices and health monitoring, but a reflective development and more detailed elaboration of the main points highlighted in the 2018 Varsity Medical Ethics debate.     

A Bayesian analysis of finite mixtures in the LISREL model

In this paper, we propose a Bayesian framework for estimating finite mixtures of the LISREL model. The basic idea in our analysis is to augment the observed data of the manifest variables with the latent variables and the allocation variables. The Gibbs sampler is implemented to obtain the Bayesian solution. Other associated statistical inferences, such as the direct estimation of the latent variables, establishment of a goodness-of-fit assessment for a posited model, Bayesian classification, residual and outlier analyses, are discussed. The methodology is illustrated with a simulation study and a real example.This research was supported by a Hong Kong UGC Earmarked grant CUHK 4026/97H. The authors are indebted to the Editor, the Associate Editor, and three anonymous reviewers for constructive comments in improving the paper, and also to ICPSR and the relevant funding agency for allowing the use of the data.

群体决策过程中的信息取样偏差

一般认为,决策群体的优势是能综合各个成员拥有的不完整信息,形成对所有决策备择方案的无偏差的认识,从而作出最佳选择。但“群体讨论中的有偏差信息取样模型’认为,群体在决策中往往表现出倾向于讨论两种信息：(1)各成员讨论前都拥有的信息;(2)支持成员在讨论前所偏好的信息。该实验通过模拟人员选拔决策形式的实验室实验,对这一模型的假设进行验证。研究结果表明,大多数群体选择了一开始受到大多数成员支持的候选人,而非实际的最佳人选;群体讨论非但未纠正,反而加强了成员对候选人原有的歪曲印象。     

键盘时间精度的一个图示法研究

以4个实验,用图示法对键盘的时间精度作了比较分析。实验1表明PES心理实验系统反应键和键盘都有良好的时间精度。实验2表明键盘的时间精度具有很大的个体差异,范围从1-2毫秒到40多毫秒,其中PS2的键盘普遍不理想。实验3表明键盘的时间精度不受转接器和计算机主频的影响。实验4使用了3名操作者,证实了这种方法的效果基本不受操作者个体差异的影响。研究演示了图示法在计算机控制的心理学实验中确定仪器的时间精度的作用,提示了实验中需要针对具体的实验条件判断时间精度是否符合实验要求,来确定是否选用特殊的反应键或者选择何种键盘作为反应的方式。
