论执行功能及其发展研究

执行功能(executive function,EF)是一个还没有明确定义的概念,但又是一个重要的概念,通常是指个体对思想和行动进行有意识控制的心理过程。目前的主要观点包括神经心理学观点、抑制控制理论、高级认知能力理论(包括工作记忆理论、抑制及工作记忆理论)和认知复杂性和控制理论。主要的研究任务类型包括卡片分类任务、延迟反应任务、基于Stroop任务的冲突反应模式任务、心理理论任务、问题解决任务、“热”执行功能任务等。未来的研究应着重弄清执行功能的本质,结合认知神经科学阐明其与脑神经结构和功能的关系,并从区分“冷”执行功能和“热”执行功能的角度,探讨以情感激活为特点的“热认知”在执行功能中的作用。     

Socio-economic status and the developing brain in adolescence: A systematic review

Socioeconomic status is associated with differences in social, cognitive, and behavioral outcomes for adolescents. Correspondingly, the period reflects continued dynamic, complex, and adaptive brain development. Research demonstrates associations between the developing adolescent brain and SES; however, such research has not been systematically integrated. We undertook a systematic search of studies and review 21 papers that examined both SES and brain development or functioning as measured during adolescence or young adulthood in nonclinical populations (13–25 years old). Few studies focused on architecture and such findings were varied. The majority of studies focused on functioning with two themes emerging. First, studies demonstrate different activation in regions of interest to cognitive and behavioral tasks relative to SES. Second, when similar neurological activation is evident, they can be related to different behavioral observations relative to SES. There is also evidence of different neurological functioning associated with SES with regard to different conceptualizations and coding of SES. Further, some of the reviewed studies identified potential mediators to the relationship, such as parenting practices, stress, and IQ. Overall, the findings suggest it is important to consider SES and neighborhood context within neuroscience research and practice.     

中学生偶像崇拜特征及其与自我评价关系研究

以233名中学生为调查对象,测查了他们偶像崇拜的结构特征、类型,及其与自我评价的关系。结果发现:①中学生偶像崇拜结构的3个因素从高到低依次为:认同、情感、行为。三因素在性别和年级上存在差异;②中学生偶像崇拜结构内部各因素之间、崇拜特征与自我评价在许多因素上存在显著相关;③中学生偶像崇拜可分为3种类型:感性型崇拜者(21.00%)、中间型崇拜者(32.88%)、理性型崇拜者(46.12%),按积极性排序依次为理性型崇拜者、感性型崇拜者、中间型崇拜者。     

Letting go of your dreams—Adjustment of child-related goal appraisals and depressive symptoms during infertility treatment

To examine the adjustment of child-related goal appraisals during infertility treatment and whether such adjustment contributes to depressive symptoms 178 (86 men, 92 women; age for women M = 33.92, SD = 0.34, for men M = 35.68, SD = 0.45) patients at an Infertility Clinic filled in child-related goal appraisal questionnaires six times: (1) before starting the hormone injections, (2) before the oocytes were retrieved, (3) after embryo transfer, (4) the day when the pregnancy test was done, and (5) two and (6) six months after the infertility treatment. At the first and last measurement times they filled in questionnaire on depressive symptoms. Appraisals concerning child-related goal changed in tandem with the treatment result, and goal adjustment had an effect on depressive symptoms.     

Abstract modal logics

In this paper we develop a general framework to deal with abstract logics associated with a given modal logic. In particular we study the abstract logics associated with the weak and strong deductive systems of the normal modal logicK and its intuitionistic version. We also study the abstract logics that satisfy the conditionC ⁺(X)=C( _in I ⁿ X) and find the modal deductive systems whose abstract logics, in addition to being classical or intuitionistic, satisfy that condition. Finally we study the deductive systems whose abstract logics satisfy, in addition to the already mentioned properties, the property that the operatorC ⁺ is classical relative to some new defined operations.Work partially supported by Spanish DGICYT grant PB90-0465-C02-01.Presented byJan Zygmunt     

The impact of parental divorce on the attainment of the developmental tasks of young adulthood

The purpose of this study was to assess the impact of parental divorce on young adult development. One hundred twenty-five participants provided demographic information and completed the PAFS-Q (college version) and the conflict subscale of the Family Environment Scale. Results indicate that parental divorce and family conflict significantly affect developmental task attainment. The interactions between sex and age and family structure (i.e., single-parent or stepfamily) were also significant predictors of post-divorce task attainment. Implications of these results for therapists as well as recommendations for future research are provided.This is a revised version of a paper presented at the annual conference of the American Psychological Association, Los Angles, California, August 1994.     

Moral growth in medical students

Although students bring to medical school a fairly well established value system, the potential for moral growth through the medical school environment and experience is substantial. The educational environment poses a succession of developmental and adaptive tasks to be accomplished. Several of these tasks are discussed here, tasks that are value-laden and involve, directly or indirectly, the interplay of ethical theory and practice. During the past quarter century, the two influences that have had the greatest impact on the moral growth and moral reasoning capacity of medical students have been the incorporation into the medical school curriculum of courses in medical humanities and the admission to medical school of an increasing number of female students. The female students have brought to medical school a level or dimension of moral reasoning (morality as care or responsibility for others) to augment the male students' focus on rights and justice considerations.     

School-Based Secondary Prevention for Children with Disruptive Behavior: Initial Outcomes

First through fourth graders from 22 suburban elementary schools were screened for cross-setting disruptive behavior as eligibility criteria for participation in a longitudinal secondary prevention study aimed at reducing the risk for serious externalizing behavioral disorders. Three hundred nine subjects participated in either a multicomponent competence enhancement intervention (MCEI) or an information/attention control (IAC) condition over a 2-year period. Following baseline measurements, initial intervention effects were assessed at the end of intervention Year 1, at the beginning of intervention Year 2 (fall of the next school year), and at the end of intervention Year 2. Multisource assessments were not supportive of the efficacy of the MCEI over the IAC condition. Children in both groups rated themselves as improved over time in terms of increased adaptive skills and decreased school problems and internalizing symptoms. Teacher and parent ratings of externalizing behavior did not yield evidence of positive change, but teachers noted improved problem solving and observers noted a decrease in behavioral interference in both groups over time, possibly as a result of maturation.     

COSMOLOGY, RELIGION, AND SOCIETY

Abstract. It is a mistake to assume that science and religion are competing accounts of the same subject matter, so that either science supersedes religion or religion anticipates science. Using the question of cosmic origins as an example, I argue that the basic task of religion is not the scientific one of establishing the most accurate acccunt of the origin of the universe. Rather, as illustrated from Jewish, Hindu, Chinese, and Buddhist thought, religion uses a variety of cosmologies to help specify the necessary terms and conditions on which human social life is possible in particular ecological niches.
