高中会考等值方法的比较研究

本研究采用随机等组设计与铆测验相结合的方案。首先验证了两随机等组的平均数、方差和分布状态无显著差异,再用随机等组的等值分作为等值效标来检验其他等值方法的误差,然后比较了在铆测验设计中三种线性等值方法（在不同总体权重下）的误差值,以选出适合高中合考的等值方法及总体权重。经研究发现：会考等值宜采用Tucker观察分数线性等值方法,并宜选择总体权重W1＝1。     

In re Edna MF: Case Law Confusion in Surrogate Decision Making

I review the recent case of Edna Folz, a 73 year-old woman who was suffering through the end stages of very advanced Alzheimer's dementia when her case was adjudicated by the Wisconsin Supreme Court. I consider this case as an example of how courts are increasingly misinterpreting the ethical and legal decision-making standards known as substituted judgment and best interests and thereby threatening individuals' treatment decision-making rights as developed by other courts over the past two decades and creating serious roadblocks to health-care providers' ability to render appropriate patient care. The Wisconsin Supreme Court held that Edna's legal guardian could not authorize withdrawal of Edna's treatment, ruling that as a matter of law, if an incompetent person is not in a persistent vegetative state, it is not in his or her best interests for life-sustaining treatment to be withdrawn unless (s)he has executed an advance directive or other statement clearly indicating his or her desires.     

遗忘症患者外显与内隐记忆实验研究:语义性启动效应任务

采用ＷＭＳ—ＣＲ和ＭＭＳＥ对临床脑损伤患者进行了认知功能与记忆功能两方面的筛选,获得９名遗忘症患者。然后采用偏好和自由联想两项语义性启动效应任务进行测验,发现遗忘症患者在外显记忆受损情况下,的确存在语义性启动效应,且与正常对照相近。推论语义性启动效应任务与遗忘患者损伤的颞叶或间脑结构无关。同时还讨论了启动效应任务,认为偏好任务采用言语性材料不是理想的方法。     

Eliminating national stereotypes: Direct versus indirect disconfirmation of beliefs in covariation

Two modes of disconfirmation of national stereotypes were compared. It was hypo-thesized that stereotypes should be revised either by stereotype-inconsistent cases from the primary target (i.e., direct disconfirmation) or by instances which belong to an alternative target but possess features stereotypic of the primary target (indirect disconfirmation). It was further predicted that politically liberal individuals would show greater change in their national stereotypes than conservatives. Two experiments were conducted in which the salience of directly and indirectly disconfirming information regarding different nations was manipulated. The results indicated that indirect disconfirmation generally had as much impact as direct disconfirmation, but that the effects were particularly visible among liberal participants. Conservatives tended to respond in a reactive manner which preserved or exaggerated their original views. A new theoretical framework for the study of stereotype change and implications for its application were discussed.     

Ratio versus difference comparators in choice.

Several theories in the learning literature describe decision rules for performance utilizing ratios and differences. The present paper analyzes rules for choice based on either delays to food, immediacies (the inverse of delays), or rates of food, combined factorially with a ratio or difference comparator. An experiment using the time-left procedure (Gibbon & Church, 1981) is reported with motivational differentials induced by unequal reinforcement durations. The preference results were compatible with a ratio-comparator decision rule, but not with decision rules based on differences. Differential reinforcement amounts were functionally equivalent to changes in delays to food. Under biased reinforcement, overall food rate was increased, but variance in preference was increased or decreased depending on which alternative was favored. This is a Weber law finding that is compatible with multiplicative, scalar sources of variance but incompatible with pacemaker rate changes proportional to food presentation rate.     

Tests of sphericity of normal distributions and the analysis of repeated measures designs

The locally best invariant test statistic for testing sphericity of normal distributions is shown to be a simple function of the Box/Geisser-Greenhouse degrees of freedom correction factor in a repeated measures design. Because of this relationship it provides a more intuitively appealing test of the necessary and sufficient conditions for valid F-tests in repeated measures analysis of variance than the likelihood ratio test. The properties of the two tests are compared and tables of the critical values of the Box/Geisser-Greenhouse correction factor are given.     

Clinical judgment in forensic neuropsychology: A comment on the risks of claiming more than can be delivered

There is a vast and growing literature in psychology demonstrating the general limits of human judgment and clinical inference. These findings clearly apply in the new specialty of clinical neuropsychology, and there is little empirical research to support the widespread belief that judgmental accuracy correlates substantially with experience, professional stature, or reputation as a neuropsychologist. However, the demand characteristics of expert testimony in the forensic arena may encourage individual neuropsychologists to state or intimate that they have unique or special expertise in understanding brain-behavior relationships, or in predicting outcomes following cerebral insult or injury. These claims will be increasingly difficult to substantiate as attorneys become more conversant with the literature on human judgment.

An overcorrection framing effect

With the “typical” attribute framing manipulation, assimilation effects have often been obtained; people often judge the attributes of a judgmental target more positively when the attributes are framed positively (e.g., 99% pure) than negatively (e.g., 1% impure). Research has not, however, explored or demonstrated the effects of correcting or overcorrecting for the frame's influence. Overcorrection framing occurs when a more positive response is produced by the negative frame. Across three experiments, overcorrection as well as typical framing effects were obtained. In Experiments 1 and 2, overcorrection effects were obtained when participants were prompted to consider complementary information and, in Experiment 3, when the frame's source was described as untrustworthy. In contrast, typical framing effects were obtained when prompts were not supplied and when the frame's source was not described as being untrustworthy. These results supported the unification model that uses a priming analysis to account for assimilation (typical framing) and contrast (overcorrection framing) effects. We discussed how overcorrection is expected with other framing manipulations, such as risky-choice framing. We provided reasons for asymmetrical correction effects and discussed implications of our analysis for holistic/analytical as well as System 1/System 2 processing styles, the influence of different amounts of cognitive resource allocations, and the possibility of a correction process involving averaging.
