4.5—7.5岁儿童对年龄认知发展的实验研究

本研究探讨儿童对年龄认知发展的过程和特点。主要结果表明:(1)在呈现刺激数量相等的条件下学前儿童对年龄时序相对可变性的认知成绩低于对相对固定性的认知,对前者的认知表现出学龄前、学龄后两个明显的发发阶段;(2)学前儿童对出生次序的认知成绩低于对年龄大小的认知成绩;(3)儿童对年龄将来时的认知表现出由近及远、由短及长的发展趋向。     

如何减少医疗差错

医疗差错是危及医疗安全、制约医疗质量、影响医患关系、引发医患纠纷的核心问题,是医院管理的重点和难点.本文通过对医疗差错的分析和美国七大减少医疗差错的借鉴来探讨如何结合我国医院的实际来有效地减少医疗差错的发生.     

Cognitive abilities in adolescent-limited and life-course-persistent criminal offenders

T. E. Moffitt's (1993a) hypothesis that adolescent-limited criminal offenders will have higher scores on tests of cognitive ability than life-course-persistent offenders was tested with 12 tests of cognitive ability given to a large and diverse sample of delinquent juveniles whose arrest records were collected over 20 years. This is the first investigation to empirically evaluate this proposal with longitudinal data obtained from a sample for a long enough time to distinguish life course patterns of crime. This study provided only partial support for Moffitt's hypothesis because the results varied by ethnicity. We found relatively consistent support for the hypothesis for Caucasians and Hispanics but no support for the hypothesis for African Americans. These findings are interpreted in terms of differences in developmental contexts for individual ethnic groups.     

不同反应方式对双作业操作信息干扰的影响

本研究采用单作业双作业操作,探讨了不同反应方式对双作业操作信息干扰的影响。实验结果证明;若采用相同的反应方式,同时操作的两种作业就会产生相互干扰,降低作业绩效;相反,若采用不同反应方式将减小双作业操作的相互干扰,提高双作业操作绩效。     

学前儿童对短时时距的区分及其认知策略

本研究以令儿童比较时距长短为手段进一步探查学前（５、６岁）儿童对短时时距的认知过程,挖掘幼儿的认知潜力。研究结果表明：１）学前５、６岁儿童已能区分只有几秒钟差异的短时时距;２）６岁儿童已能使用时间标尺测量时间,５岁儿童已有潜力把时间看成是可以计数的维量;３）两时距的时间差别大小是影响儿童认知成绩的主要因素之一。     

中学生阅读动机与阅读时间、阅读成绩的关系研究

采用问卷调查法对３５３名初、高中学生的阅读动机、阅读时间及阅读成绩进行了调查,结果发现：１．中学生的阅读动机是多维度的,包括内部动机、外部动机、社会性动机与自我效能,它们之间相互影响、相互联系;２．中学生阅读动机水平的高低与阅读时间、阅读成绩存在极为显著的正相关,其中,内部动机对中学生阅读时间、阅读成绩的影响要大于其它因素的影响;３．中学生的阅读动机发展特点具有性别帮年级差异,趋势是初中生优于高中     

Social media reduce users' moral sensitivity: Online shaming as a possible consequence

In this study, we propose that social media reduce users' moral sensitivity through the mediation of the perceived moral intensity of hostile comments, which leads to behavioral consequences for online shaming. Three separate studies were conducted to explore this statement. Study 1 (N = 160) compared moral sensitivity between participants in simulated social media situations and a control group. Study 2 (N = 412) tested the mediating role of perceived moral intensity through self-rated questionnaires. Study 3 (N = 295) examined the behavioral consequences of reduced moral sensitivity on online shaming by manipulating social media and perceived moral intensity. Across these three studies with their different methodologies, we found consistent support for our prediction that social media reduce users' moral sensitivity. Also, our findings shed light on perceived moral intensity as a mediator. As expected, less perceived moral intensity and less moral sensitivity (as serial mediators) induced by social media led to a higher tendency to participate in online shaming. In addition, our research suggests that the harmful effects of social media could be restricted by improving users' perceived moral intensity in the form of reminders. These findings provide novel insights into the underlying mechanism of cyberviolence on social media and also contribute to the literature on the antecedents and consequences of moral sensitivity.

钟面画测试及其在ADHD儿童中的研究

钟面画测试被广泛用于研究和测试老年人群中的各种认知缺陷和认知老化,是一种有用的筛选老年痴呆症病人的工具。近年来它也被用于研究正常儿童和ADHD儿童。该文回顾了钟面画测试所涉及的内部认知过程以及影响钟面画测试的各种因素、钟面画测试与执行功能测试之间的相关,并且重点回顾了钟面画测试在正常儿童和ADHD儿童中的研究。由于钟面画测试本身简便、快捷,可以迅速地大规模筛选障碍儿童,在这方面的研究具有重大的实践意义。     

小学儿童一维空间方位传递性推理能力的发展

研究了小学儿童一维空间方位传递性推理能力的发展水平及认知策略 ,同时 ,对心理模型理论进行了检验。被试为城市中等小学 7岁、9岁、11岁儿童各 2 4名 ,男女各半。 4种实验任务分别为三前提单模型、三前提双模型、四前提单模型和四前提双模型。采用个别实验 ,儿童在前提呈现的情况下进行推理。主要研究结果 :(1)从小学 7岁到 11岁 ,儿童的一维空间方位传递性推理能力明显提高 ,7岁儿童初步形成了一维空间方位推理能力 ,9岁和 11岁基本具有了这种能力 ;(2 )随着年龄增长 ,使用模型建构策略解决问题的儿童人次越来越多 ,绝大部分 11岁儿童都能使用这一策略进行推理。但即使儿童使用了模型建构策略 ,他们的推理成绩也没有反映出模型数量所造成的任务难度差异 ,即不符合心理模型理论关于模型数量的主要预期。
