鉴定结论证据能力及证明力分析——以医疗事故鉴定结论为视角

在比较大陆法系鉴定结论与英美法系专家证言的证据能力和证明力的基础上,对我国的鉴定结论证明能力与证明力问题进行了分析论证。重点对医疗事故鉴定结论的证据能力与证明力进行了分析,结合我国实际提出了相关的立法完善建议。     

What do you (think you) need? Perceived vs. experienced effects of need fulfillment on well-being

We compared two approaches towards assessing inter-individual differences in the effect of satisfaction and frustration of basic needs (autonomy, competence, relatedness) on well-being: perceived need effects (beliefs about the effect of need fulfillment on one’s well-being) and experienced need effects (the within-person coupling of need fulfillment and well-being). In two studies (total N = 1281), participants reported perceived need effects in a multidimensional way. In Study 2, daily need fulfillment and affective well-being were additionally assessed (daily-diary study; ten days). Associations between perceived and experienced need effects were significant (albeit small) for all three frustration dimensions, but only for one satisfaction dimension (relatedness), suggesting that they capture different constructs and might be related to different outcomes.     

特征归纳中关联强度与关联相似性的交互作用效应

根据特征归纳的关联相似性模型分析和三个因素实验研究发现,在基于关联相似性而进行的特征归纳中,关联强度和关联相似性两因素对归纳强度的影响存在交互作用效应。关联相似性变化对归纳强度的影响依赖于关联强度,随关联强度的增加而增加。关联强度变化对归纳强度的影响依赖于关联相似性水平：在高的关联相似性条件下,归纳强度随关联强度增加而增加;在中等关联相似性条件下,归纳强度不受关联强度变化的影响;而在低的关联相似性条件下,归纳强度随关联强度增加而减小     

人类对情绪事件效价强度的易感性及神经机制

人类情绪无疑有强度的差异。然而, 长期以来人类情绪强度的易感性未能引起足够关注。通过系统操纵刺激材料的效价强度, 作者及研究团队分别从情绪易感性本身, 情绪影响高级认知, 以及个体差异三个层次系统探讨了人类对情绪事件效价强度的易感性及其神经机制。结果发现：1)、相比正性刺激, 人类对负性刺激的效价强度更敏感, 这一效应可能跟右侧海马/杏仁核的警觉功能有关联。2)、与上述结果相一致, 不同效价强度的负性情绪对新异性加工、目标觉察、执行控制等高级认知过程具有显著不同的影响。3)、人类情绪强度的易感性具有显著个体差异：相比男性, 女性对轻度负性情绪事件易感性更强。相比中向人群, 外倾人群对愉悦刺激的情绪易感性更强, 而对轻度负性事件的情绪易感性更弱。     

Do Strength‐Related Attitude Properties Determine Susceptibility to Response Effects? New Evidence From Response Latency,Attitude Extremity,and Aggregate Indices

A great deal of research has shown that small changes in question wording, format, orordering can sometimes substantially alter people's reports of their attitudes. Althoughmany scholars have presumed that these so-called response effects are likely to be morepronounced when the attitudes being measured are weak, a number of studies have disconfirmedthis notion. This paper presents several new tests of this hypothesis using a variety of measuresand analytic techniques. The findings largely replicated previously documented effects andnon-effects but also uncovered new effects not previously tested. No single strength-relatedattitude attribute emerged as a consistent moderator of all response effects. Rather, differentindividual attributes moderated different effects, and a conglomeration of strength-relateddimensions did not emerge as a reliable moderator. Taken together, these results support theconclusions that different response effects occur as the result of different cognitive processes,and that various strength-related attitude attributes reflect distinct latent constructs rather than asingle one.     

Heart rate variability predicts self‐control in goal pursuit

The aim of our study was to investigate the effects of a failure experience on the exercise of self‐control in goal pursuit. We hypothesized that tonic heart rate variability (tonic HRV), a possible physiological marker of inhibitory capacity, increases the exercise of self‐control in the pre‐ and post‐actional phase in goal pursuit after failure. Participants received feedback for an alleged intelligence test and subsequently worked on the same test again. As indicators of exercised self‐control, we assessed self‐confidence in the pre‐actional phase and rumination in the post‐actional phase. As hypothesized, tonic HRV was positively associated with pre‐ and post‐actional self‐control, even after controlling for the effect of neuroticism. We discuss the implications of our results for the self‐regulatory strength model. Copyright © 2009 John Wiley & Sons, Ltd.     

Idealized media images and adolescent body image: "comparing" boys and girls

Sociocultural theories of body image suggest that body dissatisfaction results from unrealistic societal beauty ideals, and one way of transmitting these ideals is through the mass media. The present research aimed to examine the effect of exposure to images of idealized beauty in the media on adolescent girls’ and boys’ body image. The participants (595 adolescents) viewed television commercials containing either images of the thin ideal for women, images of the muscular ideal for men, or non-appearance television commercials. Body dissatisfaction was measured before and after commercial viewing. It was found that exposure to idealized commercials led to increased body dissatisfaction for girls but not for boys. Idealized commercials led to increased negative mood and appearance comparison for girls and boys, although the effect on appearance comparison was stronger for girls. Further, participants high on appearance investment reported greater appearance comparison after viewing idealized commercials than those less strongly invested in their appearance. The results suggest the immediate impact of the media on body image is both stronger and more normative for girls than for boys, but that some boys may also be affected.     

FOK产生机制的重新检验

以中文低频字对为学习材料,采用被试内设计的方法对FOK产生机制,即靶项目强度、线索熟悉性以及两者之间联系强度对FOK的影响进行了重新检验。实验结果表明:单独的靶项目强度对FOK判断没有影响,而单独的线索熟悉性对FOK判断存在影响,线索与靶项目联结强度对FOK判断存在影响。线索熟悉性和联结强度对FOK的影响可能相互独立。     

Moderating effect of situational strength on the relationship between personality traits and counterproductive work behaviour

The present study investigated the extent to which the strength of situations moderates the relations between personality traits and counterproductive work behaviour (CWB). It was hypothesized that the relations between personality traits and CWB would vary across strong and weak situations. In addition, there would be an interaction between conscientiousness and agreeableness in predicting CWB. As predicted, the results showed that the effect of personality on CWB depended on the strength of situations. The results also indicated that, in a weak situation only, conscientiousness has a stronger, negative relation to CWB when agreeableness is low than when agreeableness is high.
