A METHOD OF CLUSTER ANALYSIS

Different applicatiions require different systems of cluster analysis. The ways in which systems differ are pointed out. The present system was designed originally; to identify, in a homogeneous callection of questionnaire or inventory items or of tests, groups of items which can be scored as subtests, or groups of tests which can be combined to yield globa1-trait scores, but it may well be applicable to other problems.     

SCIENTIFIC METHOD AND REPRODUCIBILITY OF RESULTS

Statistical significance is not part of the scientific method. The three canons of reproducibility of an experiment: Data Matrix Homegeneity, Subject Generalizability, and Method Generalizability provide better guides to experimentation and theory development. As adjuncts to Scientific Method they provide a better basis for evaluation of statistical findings.     

CONCRETE TRANSITIVITY OF LENGTH: A METHOD OF ASSESSMENT

The problem of assessing concrete transitivity of length is explored with a non-verbal design employing nine sets of three sticks each. A training phase is used to establish the relevant variable to which the subjects must attend, to obtain a bead. A test phase consists of eight trials, in which the elements A, B, and C, are displayed in a systematic variation. A subject is said to display transitivity, when he more than five times in the eight trials chooses the largest of three sticks, A, on the basis of the information A > B and B 7< C. In a group of 20 children, varying in age between 52 and 80 months, half of the group, which is socio-economically upper-middle class, displayed transitivity. However, the youngest child displaying transitivity with six correct test-trials was 5 1/2 years old. The youngest child displaying transitivity with eight correct trials was 6 1/4 years old.     

课堂教学效果的心理学评价方法

本项研究把课堂教学看成一个动态系统。在广泛收集资料和运用特尔斐法进行调查的基础上,又经两次因子分析处理,得出问卷量表。用此量表在62名初中数学教师所教的1937名学生中取得数据。经多因素统计分析,提出课堂教学的五个子系统和二十五项心理因素的可靠性;突破了以往研究的局限性;探讨了课堂教学结构心理因素的数量化和预测教学效果的可能性;增强了评议课堂教学质量的客观性。     

飞行错觉水平评定方法的初步研究

本文从飞行错觉发生的类型和频率出发,尝试对飞行员在实际飞行中所产生的错觉水平或空间定向能力做出基本的评定。本研究采用区间模糊统计的方法,对飞行错觉的类型（倾斜错觉、俯仰错觉、方位错觉、反旋转错觉和倒飞错觉）和频率（从无、偶尔、时有、经常、总是）做了经验的赋值工作,分别计算出了这些模糊概念（除从无外）的心理量表值和模糊度。同时我们认为,飞行错觉水平是频率与类型的函数,其数学表达式为：,并将这一表达式作为评定飞行员飞行错觉水平的基本模型。     

早老性痴呆病人早期记忆损害的检测方法

采用词语延迟回忆、记忆广度和双任务工作记忆测验,研究可能用于检测(Alzheimer’s disease,AD)早期记忆损害的方法。共有4组被试：两个正常年轻人组、一个正常老年人组、一个很可能患早老性痴呆病人(Probable AD,PAD)组。结果表明：(1)正常年轻人和正常老年人的词语延迟回忆保持率没有显著差异,而PAD患者表现出明显受损;(2)两个正常年轻人组的双任务工作记忆成绩也没有显著不同,与之相比,正常老年人组有一定程度的降低,而PAD患者表现出更大程度的损害;(3)4组被试的记忆广度都不相同。这些结果提示,词语延迟回忆和双任务工作记忆测验可能能够用于检测AD早期的记忆损害。     

影响博弈结果的方法效应研究

最后通谍博弈和独裁者博弈是实验经济学的经典博弈,也被心理学家用来研究人的公平和利他行为。该研究考查了经济学和心理学通常的报酬支付方式、博弈中待分配的金额是否影响博弈结果,以及两个博弈进行组内实验时是否会产生顺序效应。结果发现支付方式和金额不影响博弈结果,但有顺序效应产生。该研究对国内研究者进一步借用这两个博弈的相关研究打下了一定的方法学基础。
