利用脑成像多体素模式分析解码认知的神经表征:原理和应用

多体素模式分析(multi-voxel pattern analysis,MVPA)是一种基于机器学习理论发展出来的新的功能磁共振数据分析技术。MVPA技术通过训练分类器,对由不同认知状态引起的多体素信号模式进行分类。与传统的基于单个体素的分析方法相比,该技术可更敏感地检测脑对认知状态的表征,并使得从神经信号解码认知状态成为可能。文章介绍MVPA技术的基本原理、分析步骤以及可以用MVPA来解决的科学问题,并对应用中可能面临的问题提供了参考建议。     

大学生利他动机的调查研究

研究的主要目的是对大学生利他动机进行调查分析。测量工具为利己性利他动机量表和利他性利他动机量表。被试取自北京5所高校的大学生1920名。结果显示：57.4%的大学生报告高度利己性利他动机。63.2%的大学生报告高度利他性利他动机。性别、独生子女、家庭地点等因素均同大学生利己性利他动机无关。独生子女、家庭地点、学校性质同大学生利他性利他动机有显著关系。     

Original thinking in preschool children: A validation of ideational fluency measures

This investigation examined the original thinking of preschool children (N=48). The instruments were lenient and stringent solution‐standard measures of original problem solving and two subsets of the Wechsler Preschool and Primary Scale of Intelligence. Scores for popular and original responses were computed for the lenient and stringent measures. Findings supported the construct validity of conceptualizations of original problem solving based on ideational fluency within the lenient measures, but not within stringent measures. Findings also indicated that the lenient measures are better predictors of real‐world original behavior than stringent measures, especially for young children. The need for development of more reliable and valid measures for assessing real‐world creative behavior is discussed.     

Psychiatry Residents' Attitudes on Ethics and Professionalism: Multisite Survey Results

Recent studies show that psychiatry residents express a relatively greater need for ethics curricula than their colleagues in other specialties. Such studies have been limited in their generalizability because they were conducted at one site. This study of 151 psychiatry residents at seven U.S. psychiatry programs aims to address that limitation. Residents were surveyed on issues pertaining to ethics and professionalism education. Participants were found to support such curricula during training and to value its relevance to the practice of psychiatry. Gender differences and the influence of the “hidden curriculum” on such results merit further study.     

Boys’ and girls’ involvement in science learning and their self‐efficacy in Taiwan

This cross‐sectional study investigated the significant differences in students’ self‐efficacy and their involvement in learning science. Nine hundred and twenty‐two elementary school fifth graders, 499 junior high school eighth graders, and 1455 senior or vocational high school eleventh graders completed the students’ questionnaire. Analyses of variance (ANOVAs) and independent t‐tests compared the significant similarities and differences across school levels and genders. The initial findings were as follows: A sharp decline in boys’ and girls’ self‐efficacy scores from elementary to secondary school levels; boys have significantly higher self‐efficacy scores than girls at vocational and senior high school levels; students with more involvement in science learning presented significantly higher self‐efficacy scores than those with less involvement. The significant discrepancies in terms of gender and age in students’ self‐efficacy and involvement in learning science need to be addressed. Implications and limitations are provided.     

Person–Job Fit and Work-Related Attitudes Among Chinese Employees: Need for Cognitive Closure as Moderator

The current research examined the moderating role of employees' need for cognitive closure in the relationship between their perceived person–job fit and their work-related attitudes. In Study 1, a survey was conducted among 176 Chinese employees from various organizations, and the results confirmed that both demand–ability fit and need–supply fit were positively related to employees' job satisfaction; moreover, these relations were stronger among people with higher need for closure than those scoring lower in need for closure. In Study 2, a survey was conducted among 242 employees from a Chinese city government, and the results replicated the findings of Study 1, but also found that need for closure moderated the relation between demand–ability fit and turnover intention. These results have important implications for research in organizational psychology and human resource management.     

Plans Are More Helpful When One Perseveres: The Moderating Role of Persistence in the Relationship Between Implementation Intentions and Goal Progress

Two studies investigated whether one dimension of action–state orientation, namely, persistence-volatility, would moderate the effect of implementation intentions on goal progress. Results from Study 1 indicated that spontaneous implementation intentions predicted goal progress 2 weeks later only among participants who scored high on persistence. In Study 2, participants were randomly allocated to an implementation intentions group and a control group. Results indicated that persistence was positively associated with goal progress among participants in the implementation intentions group but not among those in the control group. Theoretical and practical implications of these findings were discussed.     

Mass psychology of the led and the leaders

Abstract

Some salient features of a Sullivanian perspective are given as a background for a discussion of the case of Anna. Lived experience is mentioned as of equal importance as fantasy. Technically, analytic inquiry in the form of questions is stressed. In his review of the case presentation, the author observes that too much emphasis is given to content, compared to form. He notes that the therapist does not report key transference and non-transference interactions with the patient and further suggests that the patient still has significant narcissistic problems. He suggests that it is time to confront the patient with her characterological ways of relating to the analyst.
