自由回忆中元记忆监控的作用及其影响因素

采用“类信号检测论方法”,通过两个实验,研究了在记忆信息提取过程中元记忆的预见性监测判断（Feeling-of-knowing）和元控制的作用及其影响因素。实验一探讨了识记材料的难易、识记遍数对元监测判断以及输出控制中的反应标准是否有影响;实验二探讨了严格和宽松的奖惩条件对输出控制中反应标准的影响。用计算机随机呈现识记用的词表材料,识记之后让被试进行FOK等级判断和自由回忆,再用“类信号检测论”方法统计实验数据,分析各种条件下回忆成绩、FOK判断等级,计算出相应的符合率和反应标准。实验一结果表明,不同材料难度和识记遍数下的回忆成绩和FOK判断等级差异显著,但输出控制中的反应标准值没受这些因素的影响;实验二结果是严格和宽松奖惩条件下的反应标准值差异显著,严格条件下的反应标准显著高于宽松条件下的反应标准,表明奖惩条件对信息提取中的反应标准有显著影响     

Full-screen ultrafast video modes over-clocked by simple VESA routines and registers reprogramming under MS-DOS

Fast full-screen presentation of stimuli is necessary in psychological research. Although Spitczok von Brisinski (1994) introduced a method that achieved ultrafast display by reprogramming the registers, he could not produce an acceptable full-screen display. In this report, the author introduces a new method combining VESA routine calling with registers reprogramming that can yield a display at 640 × 480 resolution, with a refresh rate of about 150 Hz.

古代中国人人格结构的因素探析

以古代典籍《史记》为材料,按词汇法构建了具有相当信度和效度的古代中国人人格描述词单,施测于118名专家及研究生,令他们对《史记》中记载的102名古代中国人作评定,经由因素分析获取了以仁为核心,由仁、智、勇、隐4个因素组成的古代中国人人格维度。进而用内容分析的方法验证了该维度的稳定性,并结合中国传统哲学思想,对仁、智、勇、隐4个因素的内涵作了深入的剖析和阐释。     

理解私人意图与交际意图的ERP证据

已有的意图理解神经成像研究大多关注理解单一个体私人意图的脑功能定位, 而较少涉及两个或更多人的社会性交际意图, 大脑区分私人意图和交际意图的动态时间过程尚不清楚。本研究记录了16名健康被试理解三种不同意图任务时的脑电成分。三种意图分别为: 1)私人意图; 2)交际意图; 3)物理意图。电生理学结果表明在大脑顶区, 私人意图的N250的峰值显著大于交际意图和物理意图。在晚期阶段(300~600 ms), 交际意图的晚期正成分(LPC)的平均波幅要显著大于私人意图和物理意图。在400~600 ms时, 私人意图的LPC的平均波幅要显著大于物理意图。本研究为理解私人意图和交际意图的动态加工过程提供了神经电生理学的初步证据。     

Continuous and discontinuous drawing: high temporal variability exists only in discontinuous circling in young children

The authors studied whether the drawing variability in young children is best explicable by (a) demands on the explicit timing system, (b) an underdeveloped ability to control limb dynamics, or (c) both. The explicit timing demands were lower in continuous drawing in comparison with the discontinuous task. The authors manipulated limb dynamics by changing the number of joints involved, with line drawing requiring fewer joints than circle drawing. Results showed that young children had high temporal variability in discontinuous circling but not in other conditions. The authors argue that both explicit timing and dynamic complexity of limb control may be determinants of temporal consistency and may thus play an important role in the development of drawing and writing skills in children.     

Evaluation of a Swedish version of the Job Stress Survey

The present study assesses and evaluates the psychometric properties of a Swedish version of the Job Stress Survey (JSS; Spielberger, 1991; Spielberger & Vagg, 1999). This instrument is constructed to measure generic sources of occupational stress encountered by employees in a wide variety of work settings, settings that often result in psychological strain. The JSS was administered to metal assembly industry workers and medical service personnel in northern Sweden (n= 1186). The exploratory factor analysis showed that there is a high similarity between the present Swedish version and the original American version. Internal reliabilities of the scales, as well as test-retest reliabilities were shown to be high, and concurrent validity, as examined by comparisons with the Perceived Stress Questionnaire Index (Levenstein et al., 1993) was found to be satisfactory. The consistency of these findings is discussed with particular focus on groups of employees, gender, and cross-cultural evaluations.     

Prevalence, course, incidence, and 1-year prediction of deliberate self-harm and suicide attempts in early Norwegian school adolescents

In this survey of early Norwegian school adolescents, the prevalence, course, and incidence of self-harm behavior with or without suicide intent were examined, in addition to predictors of self-harm for a 1-year follow-up period. Lifetime prevalence rates of self-harm without suicide intent and suicide attempts were 2.9% and 3.0%, respectively, while 1-year incidence rates were 3.6% and 1.7%, respectively. In multivariate analysis, five predictors significantly differentiated self-harmers from non-self-harming adolescents. Early school adolescents having frequent or intense suicidal ideation over an extended time period and attempting self-harm repeatedly with or without suicide intent should be identified and offered treatment.     

伦理与法律对冲下的代孕思考

人类辅助生殖技术的进步使代孕成为可能,因女性子宫机能障碍而丧失生育能力的夫妇可以借别人的子宫获得与自己有遗传关系的子女,因而代孕有其社会必然性,合理的非商业化的代孕渐被多数国家接受并立法。我国禁止任何形式的代孕,但是近年来国内不少地区代孕现象屡见报端。通过对代孕现象的探讨分析,建议应从对社会和个人有利的原则出发,制定相应的伦理规范和严格的法律政策,允许代孕技术的合理应用。
