解题策略的同质性和线性逻辑斯谛模型的拟合

为探讨线性逻辑斯谛模型（ＬＬＴＭ）的拟合条件及其和解题策略同质性之间的关系,让被试比较两个负整数指数幂的大小,发现全体被试的数据不能与拉希模型及ＬＬＴＭ相拟合。把被试按其解题策略分成不同策略组后,同一策略组被试的数据可以拟合于拉希模型,但对于ＬＬＴＭ,同一策略组的数据中部分项目的拟合较好,另外一些项目的拟合较差。这一结果表明,解题策略的同质性是ＬＬＴＭ拟合的必要条件,但还不是充分条件。     

团队领导行为与团队心理安全：以信任为中介变量的研究

已有的团队领导研究着重于领导行为对团队绩效的影响,而缺乏其作用机制和路径的研究。本文选取信任与团队心理安全两个变量,以142个团队为样本,对团队领导行为是否以及如何通过信任影响团队心理安全进行实证研究。研究结果表明：(1)转换型领导行为与团队心理安全之间存在正相关关系,显著地影响团队心理安全感;(2)信任是形成团队心理安全感的重要因素之一;(3)信任在团队领导行为、团队心理安全感之间的中介效应显著。     

Uptake of Cardiac Screening and Genetic Testing Among Hypertrophic and Dilated Cardiomyopathy Families

Cardiomyopathy is a genetically and clinically heterogeneous, life threatening disease which affects people of all ages. Recent guidelines provide recommendations for cardiac screening and genetic testing in at-risk relatives, but the uptake and impact of these measures in the United States is unknown. This is a single institution retrospective study that characterizes the uptake of cardiac screening and genetic testing for relatives of a cohort of 57 probands with hypertrophic (HCM) and dilated cardiomyopathy (DCM) who underwent both clinical evaluation and genetic testing. Cardiac screening was indicated for 302 relatives. One hundred and seventy-three (57 %) completed cardiac screening. Forty of the 57 probands were mutation positive and genetic testing was indicated for 213 relatives. Eighty-four (39 %) completed genetic testing. The uptake of cardiac surveillance was greater than the uptake of genetic testing (p?<?0.0001) among relatives of mutation positive probands. Within the group of at-risk, asymptomatic relatives of probands, cardiac screening and genetic testing were positive in 25 % and 40 % of cases, respectively. These data demonstrate the important role and utility of cascade cardiac screening and genetic testing in the care of patients and families with HCM or DCM. The approach to cardiac screening and genetic testing should be family-specific and requires expertise in the genetics of cardiomyopathy.

A critique of Dennett

This essay is intended to be a systematic exposition and critique of Daniel Dennett's general views. It is divided into three main sections. In section 1 we raise the question of the nature of a plausible scientific psychology, and suggest that the question of whether folk psychology will serve as an adequate scientific psychology is of special relevance in a discussion of Dennett. We then characterize folk psychology briefly. We suggest that Dennett's views have undergone at least one major change, and proceed to discuss both his earlier and his later views.In section 2 we suggest that Dennett is correctly perceived as an instrumentalist in his earlier works. We think that Dennett later abandons this position because of general worries about instrumentalism and, more importantly, because Dennett became convinced that an instrumentalist conception of folk psychology will not enable us to vindicate the notions of personhood, moral agency, and responsibility. This left Dennett with a dilemma. On the one hand, he does not think that beliefs, etc., will turn out to be genuine scientific posits. On the other hand, he thinks that moral agency would be impossible if we could not treat beliefs, etc. as causally efficacious in some suitable sense.In section 3 we discuss Dennett's resolution of this dilemma. The key to his current view, we suggest, is the illata-abstracta distinction. Dennett holds that both illata and abstracta are real and have causal powers, even though only illata are genuine scientific posits. He suggests that beliefs etc. are abstracta, and are the subject matter of what he calls intentional system theory. The subject matter of another theory, what Dennett calls subpersonal cognitive psychology, are illata, which are subpersonal intentional states. The important point is that this distinction lets Dennett have it both ways: (i) Since beliefs are mere abstracta, we need not commit ourselves to the thesis that beliefs will turn out to be posits of an adequate scientific psychology. (ii) Since beliefs have causal power, we are assured of moral and rational agency. We shall argue that Dennett's current view is untenable. If we are right in our arguments, then Dennett's program to produce a scientifically plausible psychology, one that will turn out to vindicate folk psychology (in some suitable sense), is a failure. It fails in the following important ways: (i) What Dennett sketches — intentional system theory cum subpersonal cognitive psychology — is not a plausible scientific psychology. (ii) As a consequence, Dennett also fails to provide a satisfactory foundation for moral and rational agency.     

Do recognizable figures enjoy an advantage in binocular rivalry?

Five experiments examined whether recognizable stimuli predominate in binocular rivalry. It was found that a face predominated more than did a pattern equated for spatial frequency, luminance, and contrast; an objective reaction time procedure confirmed predominance of the face. The face was still liable to fragmentation as stimulus size increased. Observers tracked exclusive dominance of a picture of a camouflaged figure (a Dalmatian dog) prior to and then following discovery of the figure's presence; control observers received the same protocol with a scrambled version of the dog stimulus. Compared with control results, predominance of the dog picture was higher even before observers knew of the camouflaged figure. Inversion of the dog figure reduced its predominance. Binocular rivalry is sensitive to object-related, configural properties of a stimulus.     

试论庄子“亚齐物”境界及其对古代文人精神的影响

庄子哲学在先秦时期是不同于儒、墨、法等诸家政治哲学的。一部《庄子》,诙诡奇谲,洋洋洒洒,倾注的是庄子对生命深切的终极关怀———人的命运和精神自由。庄子笔下,各色人物你方唱罢我登场。当中有逍遥游于天地,与造化相流行的神人,以己意出法令的人间帝王,欲致君尧舜的士人,恶于世的隐者,普通的匠     

Framing Charity Advertising: Influences of Message Framing,Image Valence,and Temporal Framing on a Charitable Appeal1

This study examined when and how charitable advertisements could be effective in the context of child poverty. An experiment investigated the influences of message framing, image valence, and temporal framing on a charitable appeal. The results indicate that image valence enhances framing effects on advertising effectiveness of a charitable appeal when the image is congruent with the framed message, especially when the image and the message are presented negatively. A short‐term temporal frame facilitates effects of a negatively framed message with a negative pictorial presentation. Alternatively, a long‐term temporal frame increases advertising influences of a positively framed message with a positive pictorial image. Relevance for information processing of charity advertising is discussed.

心理契约履行和组织公民行为之间的关系研究

本研究在对159名在职人员的调查的基础上,比较全面地考察了心理契约的内容,并对心理契约实际履行情况带来的影响做了研究。结果发现：不同心理契约履行水平下,员工的组织公民行为存在显著差异。因此,我们可以认为如果要提高员工的组织公民行为,组织应该最大程度地履行员工的心理契约。这反映了员工与组织之间互惠交换关系的本质。另外,不同内容的心理契约履行带来的组织公民行为的提高,具体表现在不同方面。
