A Two-Dimensional Theory of Health

The starting point for the contemporary debate about theories of health should be the holistic theory of Lennart Nordenfelt, claims George Khushf, not the refuted theory of Christopher Boorse. The present paper is an attempt to challenge Nordenfelt and to present an alternative theory to his and other theories, including Boorse’s. The main problems with Nordenfelt’s theory are that it is relativistic, that it leads to counter-intuitive results as to what goals can count as healthy, that it focuses on the wrong kind of abilities, that it makes measuring health extra difficult, and that it does not give us a sufficient account of health, at most a necessary one. The alternative theory proposed is two-dimensional. First, health is to have developed the abilities and dispositions that members of one’s culture typically develop, and be able to use them, in acceptable circumstances; and second, health is to experience positive moods and sensations, the kinds that have internal causes. The theory solves the problems attached to Nordenfelt’s theory by not being individual relativistic, by eliminating the goals in the definition, by giving an alternative interpretation of “ability,” by making health easier to measure, and by adding the dimension of well-being that, together with health as ability, not only gives us a necessary, but also a sufficient, account of health.     

Recycling,evolution and the structure of human personality

Lower childhood cognitive ability may be a risk factor for greater cognitive decline in late life and progression to dementia. To assess variation in age-related cognitive change, it is helpful to have valid measures of cognitive ability from early life. Here, we examine the relation between childhood intelligence and cognitive change in later life in two samples, one born in 1921 and the other in 1936. All participants completed the same test of mental ability (one of the Moray House Test series) at age about 11 years, and were re-examined on Raven’s Progressive Matrices at age 77 (1921-born) or age 64 (1936-born). Where possible, the 1921 sample was re-tested at the age of about 80 years old and the 1936 sample re-tested at about 66 years. After taking into account various covariates, including sex, education and occupation, childhood intelligence was a significant predictor of cognitive change in later life. Results were in the direction that participants with lower childhood mental ability experienced relatively greater cognitive decline, whereas those of higher childhood mental ability showed improved performance. This result suggests that higher premorbid cognitive ability is protective of decline in later life.     

On the validity of Raven’s matrices test: Does spatial ability contribute to performance?

The paper reports on an investigation of the convergent and discriminant validity of Raven’s matrices in considering reasoning and spatial abilities. Raven’s advanced progressive matrices (APM) and four scales representing reasoning, visualization, mental rotation and closure were applied to a sample of N = 280 university students. The data were investigated by means of structural equation modeling. The results demonstrated convergent validity of APM with respect to reasoning. In contrast, in investigating discriminant validity substantial correlations of moderate size between APM and the scales representing spatial abilities were observed. However, the investigation of the structure of the prediction of APM revealed that the scales representing spatial abilities did not improve the prediction based on the reasoning scale alone at the latent level. Consequently, it is suggested that Raven’s matrices show good convergent validity and slightly impaired discriminant validity.     

大学生自理能力现状分析及其培养

采用自编的“大学生自理能力问卷”,对我国大学生自理能力的现状进行了调查。结果表明：大学生自理能力总体状况是稳定的;在情绪情感状态、日常管理、职业准备、行为效能和交往以及自我控制能力等五个方面薛在年级差异;独生子女与非独生子女在行为效能和交往以及自我控制能力方面存在显著差异;大学生的自理能力随年级的升高将越强。本研究从家庭和社会、大学以及大学生自己的责任三方面提出了关于大学生自理能力培养的建议。     

应用题结构分析训练对提高小学生解题能力的实验研究

实验以小学四年级学生为被试,采用完全随机化等组设计。实验组采用应用题结构分析训练教学模式,控制组在同等时间内,采用常规教学模式作相同的习题练习。实验结果表明：（１）应用题结构分析训练可显著提高小学生解应用题的能力,中等生受益最大;（２）该模式训练效果与学生的智力水平呈中等程度正相关;（３）学生对该训练模式持肯定态度,反应积极。     

8─11个月婴儿迂回行为发展特点与学习能力的研究

采用程序标准化的婴儿迂回行为测验,探讨了２４４名８─１１个月婴儿的迂回行为发展特点及学习能力。结果表明：（１）８─１１个月婴儿的迂回行为水平表现出随婴儿月龄的增长而提高的趋势。（２）８─１１个月的婴儿具有从反复尝试中学会迂回行为的可能性,其中９、１０个月婴儿的学习可能性较大,而８个月婴儿的学习可能性较小。（３）８──１１个月婴儿的学习速度随月龄增大而提高     

一般能力倾向成套测验简介及其中国试用常模的修订

本文对一般能力倾向成套测验作了简要的介绍。为了试用,对它进行了修订。版本是以日本劳动省１９８３年修订版为蓝本的。日本的版本是来自美国。为了适合国情,对该测验在三个方面作了微小的变动。修订工作自１９８９—１９９２年初。标准化样组是由全国１７个中等以上城市初二至高三学生２１４８名构成的。男女学生的比例为１：１。该测验在结构效度上有很好的证据,稳定信度分数相当好。     

识字能力的单维性检验研究

本研究以义务教育阶段学生识字量测验为工具,综合运用探索性结构方程建模(ESEM)以及非参数项目反应理论中的摩根量表(Mokken量表)和DETECT分析方法,探讨了识字能力的维度。探索性结构方程建模结果显示,识字的单维性模型优于多维模型,多维的结果更多的体现出一个难度维度的特征,即字频的作用。Mokken量表分析结果显示,1~2年级和3~9年级测验更倾向于单维量表的特征。DETECT分析结果显示,两个测验的D值趋近于零,表明识字能力是单维能力。结合三种分析方法,识字能力具有单维性。     

决策信心校准水平对元认知监控作用的影响

决策信心是个体对自身决策正确性的主观评价,是对决策过程的元认知体验。决策信心校准指决策信心水平与实际的决策正确率之间的匹配程度,其指标有信心水平和决策正确率的相关系数及Type II信号检测论中的ROC曲线下面积（Aroc）等。已有研究发现进行决策信心评估能够增强对当前或后续决策的元认知监控作用,但目前尚不清楚这种效应是否依赖于个体的决策信心校准水平。本研究通过设置知觉决策后是否进行决策信心评估（有信心评估与无信心评估）两种条件,考察个体决策信心的校准水平（Aroc）对元认知监控作用的影响。结果显示：1）与无信心评估条件相比,有信心评估的决策反应时显著增长,决策正确率显著提高（p<0.005）;2）Aroc与有、无信心评估条件下决策正确率的增加值显著正相关（r=0.25,p=0.034）,且高Aroc组的决策正确率增加值显著高于低Aroc组（p<0.05）。结果表明,在知觉决策过程中加入决策信心评估具有增强元认知监控作用的效应,体现为决策时间的增长和决策正确率的提高。并且,这种效应的大小依赖于个体的决策信心校准水平,校准水平越高元认知监控作用越好。
