Sex differences in performance attribution and contingency judgment

In two studies, male and female subjects were given attribution measures before and after performance on a novel finger maze. Neither study revealed any sex differences in expectancy and anticipated attributions prior to maze performance. In Experiment 1, no sex differences in attributions were obtained regardless of whether the outcome was success or failure. In Experiment 2, where the outcome was made completely noncontingent on behavior, females had greater illusion of control as well as higher luck attribution. This paradoxical finding was interpreted as reflecting females' tendency to depend on external and internal attributions simultaneously.The data presented here are based on a larger research project on reinforcement contingencies and performance attributions supported by a research grant from the Social Sciences and Humanities Research Council of Canada.     

Matrix derivatives and its applications in statistics

The scalar values of differentials rather than symbolic derivatives are treated here. This approach simplifies the differential calculus in statistics because, often, the linear representations of differentials in statistics (1) are complicated, (2) depend on the bases used, (3) can be obtained by the scalar values on elements of a given basis, and (4) are not necessary for many problems of finding maxima and minima. Among others, a product rule is obtained in a very general and simple form. The results are applied to certain problems in multivariate statistical analysis that are useful to psychology and other behavioral sciences.     

Stress, social support, and teacher burnout in Macau

The present study attempts to document the difficulties that teachers in Macau encountered in their work, the extent to which the job-related difficulties would induce burnout, and whether or not social support could buffer the adverse effects of stress on burnout. In-service teachers enrolled in a teacher training program filled out questionnaires addressing the variables of interest. The results indicated that difficulties with fellow teachers, supervisors, students, and parents of students were associated with burnout. Conjectures were made regarding the noneffectiveness of social support.     

Value and Sex-Role Orientation of Chinese Adolescents

The value preference of a sample of Chinese adolescent high school students, as measured by the Rokeach Value Survey, showed a greater emphasis on the personal and competency values. Specifically, adolescents in this study tended to favour a joyous, comfortable, free, and enjoyable lifestyle. It was found that the four most important terminal values were: freedom, true friendship, happiness, and a comfortable life, while the four least important were: mature love, national security, an exciting life, and salvation. The four most important instrumental values included: capable, cheerful, broadminded, and intellectual, while the four least important included: logical, imaginative, clean, and obedient. The relationships between value preference and sex role were examined and close relationships were found, especially with respect to the instrumental values. Specifically, masculine adolescents were more agentic and instrumental, and feminine adolescents were more expressive and communal in their value preference. Androgynous adolescents were found more similar to the masculine than to the feminine group. In addition, regression analyses showed that masculinity tended to have more pervasive effects than femininity on adolescents' value preference. The implications and significance of the findings of this study in contrasting the general collectivistic depiction of Chinese and in relating to adolescent development, are discussed.     

Evaluating Rehabilitation Caseload Management Skills Through Computer Simulations

In this article the authors report on the development and validation of a computer-based rehabilitation caseload management simulation as a teaching and evaluation tool in counselor education. The computer simulation was administered to 18 rehabilitation students and 18 rehabilitation counselors. Their performance on the simulation was evaluated using six caseload management performance indicators. These performance indicators, derived from the computer simulation, were found to be effective in differentiating the student group from the experienced counselor group using discriminant analysis. Implications for the use of computer simulations in rehabilitation counselor education and future research directions are discussed.     

Component Skills as Predictors of Chinese Reading Proficiency in Primary School Children

This study was designed to examine the relevance of some cognitive skills to Chinese reading and to identify those that distinguish readers of different proficiency levels. Third-, fourth-, and fifth-grade children were given two sets of tests, the Chinese Reading Proficiency Test and five component skill tests. Skills in word recognition and in comprehension were examined through tasks measuring component detection, lexical coding, memory for gist, knowledge of syntax, and use of context. Subjects' responses on the knowledge of syntax task and the lexical coding task were found to be most effective in predicting reading proficiency of the third graders, but not the fourth- and fifth-grade children. Instead, use of context task was the best predictor of the older children's reading proficiency.     

Acculturation, peer relations, and delinquent behavior of Chinese-Canadian youth

Studies have reported that youth of Chinese descent in North America tend to have lower rates of delinquency. Some investigators have attributed this phenomenon to the restraining effects of Chinese culture. In this study, acculturation, peer relations, and delinquency were examined in a sample of Chinese-Canadian youth. The results revealed that adherence to Chinese culture was related to lower delinquency, whereas the opposite was true for North American acculturation. It was found that association with delinquent peers was positively related and attachment to peers negatively related to delinquency, as predicted by differential association and control theories, respectively. Moreover, acculturation was positively related to association with delinquent peers and attachment to peers. However, there was the unexpected finding that association with Chinese peers was positively related to delinquency. These seemingly contradictory findings demonstrate the dilemma experienced by Chinese youth in North America.     

Sex differences on the MMPI-2 substance abuse scales in psychiatric inpatients.

Sex differences on the MMPI-2 addiction scales (MacAndrew Alcoholism Scale-Revised, Addiction Acknowledgement Scale, Addiction Potential Scale) and their ability to distinguish between substance-abusing and nonabusing psychiatric inpatients were examined. Men obtained higher mean raw scores than women on the MacAndrew Alcoholism Scale-Revised and the Addiction Acknowledgement Scale, and substance abusers scored higher on all three scales. Even relatively low cutoff scores, however, on the MacAndrew Alcoholism Scale-Revised resulted in false negative rates of 37 to 39%. The results support the utility of the MMPI-2 substance abuse scales; however, lower cutoff scores should be used with women and within a psychiatric population.     

On A Semantic Interpretation Of Kant's Concept Of Number

What is central to the progression of a sequence is the idea of succession, which is fundamentally a temporal notion. In Kant's ontology numbers are not objects but rules (schemata) for representing the magnitude of a quantum. The magnitude of a discrete quantum 11...11 is determined by a counting procedure, an operation which can be understood as a mapping from the ordinals to the cardinals. All empirical models for numbers isomorphic to 11...11 must conform to the transcendental determination of time-order. Kant's transcendental model for number entails a procedural semantics in which the semantic value of the number-concept is defined in terms of temporal procedures. A number is constructible if and only if it can be schematized in a procedural form. This representability condition explains how an arbitrarily large number is representable and why Kant thinks that arithmetical statements are synthetic and not analytic.     

重复知盲:刺激呈现时间及作业对反应时的影响

本研究用汉字材料及反应时的数据来探讨重复知盲现象及有关机制。在实验一中,被试必须判断快速连续呈现的两个字究竟是否包含两个或是只有一个动物字。结果显示在７０毫秒时,有重复知盲现象（重复动物字组比非重复动物字组的反应时为长）;在１００毫秒时则无;另外,在２００毫秒时则有重复启动现象产生（重复动物字组比非重复动物字组的反应时为短）。实验二采用同样的材料及呈现方法,但被试只需要判断以７０毫秒呈现之实验材料中的第二个字是否动物字。结果发现类似重复启动的现象,这些结果显示,呈现时间与作业是决定重复刺激究竟造成知盲或启动效应的重要因素。本文另外还讨论本研究的方法与结果对了解重复刺激心理加工的可能贡献。
