《易数钩隐图》作者等问题辨

自南宋时起,《易数钩隐图》一书的作者就有二字与二籍贯的争议。本文就有关问题进行了考辨。得出北宋有二刘牧、前刘牧著《易数钩隐图》、黄黎献为之续补等结论。最后指出,彭城刘牧的道学思想应当在宋明理学中占有一席之地。     

Influential observations in principal factor analysis

We propose a method for detecting influential observations in iterative principal factor analysis. For this purpose we derive the influence functionsI(x; LL ^T ) andI(x; ) for the common variance matrixT =LL ^T and the unique variance matrix , respectively, in the common factor decomposition =LL ^T + . A numerical example is given for illustration.The authors are grateful to Tomoyuki Tarumi and Atsuhiro Hayashi for their kind permission to use their software Seto/B for drawing Figures 1 and 2 and to anonymous reviewers for comments on the paper.     

Visually guided catching and tracking skills in pigeons: A preliminary analysis

Research on reaching, tracking, and catching in the pigeon has been hampered by limitations of technology. A new system was developed in which the target was a small rectangle presented on a video display terminal and the pecking response was detected with touch technology. The target moved up and down vertically with sinusoidal velocity. A coincidence between the location of the pigeon's beak and the cursor produced reinforcement. The pigeon pecked ahead and behind the target, but most pecks occurred behind the target so the dominant tracking strategy was lagging. The pigeon was adept at “catching” the target at many locations throughout the trajectory. Transfer of motor learning was tested on probe trials during which the trajectory changed from vertical to horizontal. On transfer trials the pigeons' dominant pattern of pecking immediately shifted from vertical to horizontal. The motor skill displayed by the pigeons was flexible and adaptive, suggesting that the pigeons had learned to track the cursor.     

祖辈协同教养与幼儿错误信念理解能力的关系:亲子依恋与祖辈同住的作用

为考察祖辈协同教养与幼儿错误信念理解之间的关系以及幼儿亲子依恋的中介作用,采用方便抽样的方法,调查了某城市三所幼儿园345名小班至大班的祖辈协同教养幼儿及其家庭教养人。对幼儿使用操作任务考察错误信念理解能力,对其家庭教养人利用自陈式问卷收集家庭教养方式和亲子依恋等数据。结果显示：(1)祖辈协同教养类型显著影响幼儿的错误信念理解水平和亲子依恋,“有祖辈同住”协同教养幼儿的错误信念理解水平以及依恋的安全性均显著低于“无祖辈同住”协同教养幼儿;(2)亲子依恋在祖辈协同教养的民主信任和教养冲突两个维度与幼儿错误信念理解能力之间分别存在显著的中介作用;(3)祖辈协同教养类型在教养冲突、亲子依恋、错误信念理解能力的中介模型中起调节作用,在“有祖辈同住”条件下,协同教养冲突显著负向预测幼儿的亲子依恋安全感。     

汉字词特征语义提取的实验研究

本研究运用语义判断的方法,对汉字词特征语义的提取做了初步的探讨,被试是28名大学生。实验结果表明,汉字形声字的义符在汉字词定义特征语义提取中有重要作用,在义符与词义一致时,能加速词的定义特征语义的提取。义符对词的特有特征的语义提取无作用,而特有特征的强度能很好地预测提取时间。本研究还发现,词的熟悉性和该词距其上属的语义距离对词的定义特征的语义提取亦有重要影响。     

Forms of Authority and the Real Ad Verecundiam

This paper provides a typology of appeals to authority, identifying three distinct types: that which is based on a command; that which is based on expertise; and that which is based on dignity. Each type is distinguished with respect to the reaction that a failure to follow it ordinarily evokes. The rhetorical roots of Locke's ad verecundiam are traced to the rhetorical practices of ancient Rome.     

The stability of status orientations among young,white, rural women from three southern states

This paper reports the results of a panel study of young, white, rural women from Georgia, South Carolina, and Texas (N = 138). The study was primarily concerned with how social origin variables affected early educational and occupational orientations and how early states of these orientations affected the orientations themselves at a later point in time. The results indicated that mother's education had a greater effect than father's education, but in either case the effect is mediated by intervening influences such as early aspirations and expectations. These young women held very traditional status orientations (with 60% projecting the occupations of beautician, nurse, stenographer, or school teacher), and their orientations were quite stable between their sophomore and senior years in high school. Since there has been so little work reported on the status attainment process for women, and rural women in particular, this study does offer a limited insight into this phenomenon.     

Teaching awareness of strategic behavior in combination with strategy training: Effects on children's memory performance

The present study examined the effectiveness of two components (rehearsal training and strategy awareness) of an instructional package designed to train the developmentally young in the use of mature information processing techniques. Two groups of children of equivalent developmental age (MA = 8), one mildly retarded and the other of average intelligence, participated. Rehearsal training was effective in improving recall scores on the training task; however, neither rehearsal training, memory awareness, nor their combination significantly altered memory performance on the generalization tasks. There was evidence, however, that the combination of rehearsal training and strategy awareness did increase the likelihood of strategy transfer on the generalization task (recognition) which most closely resembled the training task. Post-task questioning revealed that instructions concerning memory awareness did improve subjects ability to verbalize appropriate strategic behavior; however, these improvements were not consistently translated into either actual use of a rehearsal strategy or improved performance. Discussion centered on the implications of these results and on the need for increased research on the metamnemonic skills involved in strategy generalization.     

Is monkey maternal abuse of offspring aggressive behavior?

This study was intended to probe the aggressive nature of monkey infant abuse by comparing the morphology of abusive behavior patterns with that of patterns allocated to both aggression and other categories of behavioral repertoires of macaques. This morphological analysis indicated that most abusive patterns should not be classified in the aggression category as they, at the motor end, differ greatly from macaque aggressive acts. In contrast, they perfectly resemble behaviors that monkeys usually display while manipulating inanimate objects. The implications of this finding for the pathogenic study of monkey infant abuse are discussed.
