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。     

从主文化视角看20世纪我国社会道德规范体系的演变与重建

根据社会学关于主文化的理论观点,可以将主义化细分为主导文化、主体文化、主流文化.回顾20世纪中国文化的发展历程,可以看到,主文化在三个维度上一直处在消长与变革之中,并由此使社会道德规范体系呈现出相应的演变历程.针对改革开放后我国社会道德规范体系"碎片化"的态势,要大力建设以"社会主义和谐文化"为标志的主文化,紧紧抓住社会主义核心价值体系这个根本,尊重差异、包客多样,构建中国特色社会主义道德规范体系.     

Asymmetrical stimulus generalization following differential fear conditioning

Rodent ultrasonic vocalizations (USVs) are ethologically critical social signals. Rats emit 22 kHz USVs and 50 kHz USVs, respectively, in conjunction with negative and positive affective states. Little is known about what controls emotional reactivity to these social signals. Using male Sprague–Dawley rats, we examined unconditional and conditional freezing behavior in response to the following auditory stimuli: three 22 kHz USVs, a discontinuous tone whose frequency and on–off pattern matched one of the USVs, a continuous tone with the same or lower frequencies, a 4 kHz discontinuous tone with an on–off pattern matched to one of the USVs, and a 50 kHz USV. There were no differences among these stimuli in terms of the unconditional elicitation of freezing behavior. Thus, the stimuli were equally neutral before conditioning. During differential fear conditioning, one of these stimuli (the CS⁺) always co-terminated with a footshock unconditional stimulus (US) and another stimulus (the CS⁻) was explicitly unpaired with the US. There were no significant differences among these cues in CS⁺-elicited freezing behavior. Thus, the stimuli were equally salient or effective as cues in supporting fear conditioning. When the CS⁺ was a 22 kHz USV or a similar stimulus, rats discriminated based on the principal frequency and/or the temporal pattern of the stimulus. However, when these same stimuli served as the CS⁻, discrimination failed due to generalization from the CS⁺. Thus, the stimuli differed markedly in the specificity of conditioning. This strikingly asymmetrical stimulus generalization is a novel bias in discrimination.     

Disjunctivism, contextualism and the sceptical aporia

We know things that entail things we apparently cannot come to know. This is a problem for those of us who trust that knowledge is closed under entailment. In the paper I discuss the solutions to this problem offered by epistemic disjunctivism and contextualism. The contention is that neither of these theories has the resources to deal satisfactory with the problem.     

The role and impact of mental simulation in design

Although theories of mental simulations have used different formulations of the premises of ‘thought experiments’, they can be fitted under a minimalist hypothesis stating that mental simulations are run under situations of uncertainty to turn that uncertainty into approximate answers. Three basic assumptions of mental simulations were tested by using naturalistic data from engineering design. Results from the design protocols showed (1) initial representations in mental simulation had higher than base‐rate uncertainty, (2) uncertainty in mental simulations were lowered after simulation runs, (3) resulting representations had more approximations than base‐rate or initial representations. Further, the reference to external representational systems (sketches and prototypes) was examined. It was found that prototypes had fewer technical/functional simulations compared to sketches or unsupported cognition. Although prototypes were associated with more approximation than unsupported cognition, the different external representation categories did not differ in information uncertainty. The results support the minimalist hypothesis of mental simulations. Copyright © 2008 John Wiley & Sons, Ltd.
