登楼试验在低肺功能食管癌患者术前心肺功能评估中的作用研究

对需行食管癌手术的418例患者行术前静态肺功能检查后,按第一秒用力呼气量占预计值百分比（FEV1％）分为两组：肺功能正常组（NPF）和低肺功能组（LPF）。NPF组直接手术治疗,LPF组补充登楼试验,选择部分患者经术前功能锻炼后手术治疗,观察两组的临床情况。静态肺功能测定结果较差而进行登楼试验筛选后的部分患者可以通过功能锻炼提高心肺功能储备,从而能够接受手术治疗。     

Creating distinct implicit and explicit attitudes with an illusory correlation paradigm

Two studies used an illusory correlation procedure to test whether distinct implicit and explicit evaluations can result from the same learning episode. All participants learned twice as much about the qualities of one group (majority) than another (minority). In one condition, the ratio of positive to negative information was equal between groups. In other conditions, the majority group showed proportionally more positive qualities than the minority group, or vice versa. Participants in the pro-majority and pro-minority conditions formed both implicit and explicit attitudes consistent with the attitude induction. Participants in the illusory correlation condition showed the expected preference for the majority group (the illusory bias), but showed no implicit preference, suggesting distinct influences on implicit and explicit attitude formation. The effects are consistent with dual-process models in which implicit attitudes reflect accounting of covariation and explicit attitudes reflect interpretative judgments of that covariation.

The greatest lower bound to the reliability of a test and the hypothesis of unidimensionality

To assess the reliability of congeneric tests, specifically designed reliability measures have been proposed. This paper emphasizes that such measures rely on a unidimensionality hypothesis, which can neither be confirmed nor rejected when there are only three test parts, and will invariably be rejected when there are more than three test parts. Jackson and Agunwamba's (1977) greatest lower bound to reliability is proposed instead. Although this bound has a reputation for overestimating the population value when the sample size is small, this is no reason to prefer the unidimensionality-based reliability. Firstly, the sampling bias problem of the glb does not play a role when the number of test parts is small, as is often the case with congeneric measures. Secondly, glb and unidimensionality based reliability are often equal when there are three test parts, and when there are more test parts, their numerical values are still very similar. To the extent that the bias problem of the greatest lower bound does play a role, unidimensionality-based reliability is equally affected. Although unidimensionality and reliability are often thought of as unrelated, this paper shows that, from at least two perspectives, they act as antagonistic concepts. A measure, based on the same framework that led to the greatest lower bound, is discussed for assessing how close is a set of variables to unidimensionality. It is the percentage of common variance that can be explained by a single factor. An empirical example is given to demonstrate the main points of the paper.

Reliability as a function of the number of item options derived from the “knowledge or random guessing” model

For (0, 1) scored multiple-choice tests, a formula giving test reliability as a function of the number of item options is derived, assuming the knowledge or random guessing model, the parallelism of the new and old tests (apart from the guessing probability), and the assumptions of classical test theory. It is shown that the formula is a more general case of an equation by Lord, and reduces to Lord's equation if the items are effectively parallel. Further, the formula is shown to be closely related to another formula derived from Lord's randomly parallel tests model.     

不同类型考试焦虑影响考试成绩的差异模式

调查了440名高中生,以不同类型考试焦虑为预测变量,以掌握目标、情绪性、应对反应、考试自我效能感、成绩-接近目标、成绩-回避目标、担忧、学习和考试技能、认知干扰为中介变量,期末数学考试成绩为最终结果变量,探讨不同类型考试焦虑影响考试成绩的模式。结果表明:不同类型考试焦虑具有不同的影响考试成绩的模式,即存在认知主导型模式(简称C模式)、生理唤醒主导型模式(简称P模式)、技能缺乏主导型模式(S模式)等三种不同的模式。担忧是C模式中的主要中介变量,P模式的主要特征是担忧对情绪性存在显著影响,S模式的特点是中介变量较少,学习和考试技能变量受考试焦虑和考试自我效能感双重影响并作用于考试成绩。

A Swedish non-word repetition test for preschool children

A Swedish non-word repetition test for preschool children was constructed with the aim of measuring short-term phonological memory, which has been shown to correlate with language development and language proficiency. Normative data based on results for 200 children four to six years of age are presented. An item analysis of the original 30-item test resulted in a shortened 24 non-word version found suitable for four- to six-year old children. Results for this shortened version, which had a Cronbach's alpha of 0.73, showed longer non-words to be more difficult to repeat than shorter ones, and significant effects of age and compatibility of the tester's and the child's accent, but not of gender. The results are discussed within the framework of Baddeley's working memory model.     

The Early Numeracy Test in Finnish: children's norms

This article concerns psychometric aspects of the Finnish Early Numeracy Test, which has been translated from the original Dutch Early Numeracy Test. The advantage of the test is that young children's numerical skills can be assessed systematically, which was not possible previously in Finland. A norm study was conducted in which the test was administered to a representative sample of 1,029 Finnish children. The reliability and validity results justify the use of the test as an early-childhood screening test and in research on number sense. The indicative effects of gender, parental professional education, domicile and number of siblings are discussed.
