合成词加工中的词频、词素频率及语义透明度

通过变化汉语合成词的词素累积频率的方法,考察表面频率和语义透明度对加工速度的影响。研究发现,当控制透明度时,高表面频率词中存在词素累积频率效应,即词素频率越高反应越快;而在低表面频率词中没有。当控制表面频率,变化词素频率和透明度时,在透明词中,词素累积频率高的比低的加工快;但在不透明词中;这种反应趋势反转了：词素频率越高反应越慢。     

Postural coordination patterns as a function of dynamics of the support surface

The present study investigated the compensatory postural coordination patterns that emerge in the face of dynamic changes in the surface of support. Adult subjects stood on a moving platform that was sinusoidally translated in the anterior-posterior direction. The frequency and amplitude of the support surface translation were manipulated over a wide range of parameter values. The results revealed that as the frequency of platform motion increased, the postural system systematically exploited the available joint-space degrees of freedom and generated four distinct postural coordination modes (a rigid mode --> ankle mode --> ankle-hip mode --> ankle-hip-knee mode). It appears that upright standing posture has a small set of coordination patterns that are particular to the dynamics of the surface of support.     

任务图式对文章修改的影响研究

本研究探讨任务图式对文章修改的影响。高低水平的作者先完成一个写作任务,再修改文章的初稿。修改时,实验组学生先接受关于正确修改的任务图式指导,控制组学生则直接进行修改。实验结果表明,任务图式指导有明显的主效应,高低水平作者均提高了对字面错误与意义错误的正确修改,而水平间的差异主要表现在意义错误的修改上。本研究还分析了任务图式指导对修改的字数(包括改变意义与保留意义的字数)、修改的句法水平(包括字、词和句子)以及修改的方式(包括插入、替换、删除和移动句子)的影响。     

Effect of Heel Heights on Female Postural Control During Standing on a Dynamic Support Surface With Sinusoidal Oscillations

The authors aimed to investigate female balance or stability control with comparative analysis of the center of pressure trajectory and plantar pressure distribution with different high-heeled shoes while standing on a dynamic surface with multidirectional perturbations. College females with at least 2 years' history of wearing high-heel shoes voluntarily participated in the test with a Novel Pedar insole (Novel, GmBH, Munich, Germany. With heels height increasing, the pressure time integral obviously transfer to the medial forefoot region, with center of pressure trajectory medially deviated significantly, either under anteroposterior or mediolateral perturbations. The passive plantarflexion position of ankle incurred by high heel increased the range of motion in the frontal plane but decreased ankle stability, thus increasing the challenge of body balance maintenance.     

Predictors of volitional personality change in younger and older adults: Response surface analyses signify the complementary perspectives of the self and knowledgeable others

Goals to change personality traits have been linked to self-rated Big Five traits. Extending previous research, we investigated the associations between change goals and diverse personality characteristics (e.g., self-esteem), other-rated Big Five traits, and self-other agreement in an age-heterogeneous sample (N = 378). Results replicated previous associations of change goals with age and self-rated traits. Additionally, change goals were stronger when others rated a person’s traits as low and when self-other agreement about traits was greater for extraversion, agreeableness, and conscientiousness. Associations of additional personality characteristics with change goals diminished when we controlled for the Big Five traits. We conclude that goals to change personality traits primarily reflect the perspective of the self and, for some traits, of knowledgeable others.

Values and adolescents' self-esteem: The role of value content and congruence with classmates

The study examined the relations between adolescents’ self-esteem and two aspects of values: content and congruence with classmates. Using a large sample of Israeli adolescents (N = 1,683; M_age = 14.36, SD = 2.24, range = 11–18, 54.31% females), we found that self-esteem related negatively to self-enhancement values and positively to conservation values using zero order correlations. Multilevel polynomial regressions, controlling for demographic differences, found significant quadratic associations of self-esteem with self-enhancement, self-transcendence, openness-to-change, and conservation values. Furthermore, using Response Surface Analyses, it was found that adolescents who were congruent with their classmates’ self-enhancement and self-transcendence values showed the highest levels of self-esteem. The findings point to the importance of social context for the relations between values and self-esteem among adolescents.     

Sex-specific variation in facial masculinity/femininity associated with autistic traits in the general population

Reports linking prenatal testosterone exposure to autistic traits and to a masculinized face structure have motivated research investigating whether autism is associated with facial masculinization. This association has been reported with greater consistency for females than for males, in studies comparing groups with high and low levels of autistic traits. In the present study, we conducted two experiments to examine facial masculinity/femininity in 151 neurotypical adults selected for either low, mid-range, or high levels of autistic traits. In the first experiment, their three-dimensional facial photographs were subjectively rated by 41 raters for masculinity/femininity and were objectively analysed. In the second experiment, we generated 6-face composite images, which were rated by another 36 raters. Across both experiments, findings were consistent for ratings of photographs and composite images. For females, a linear relationship was observed where femininity ratings decreased as a function of higher levels of autistic traits. For males, we found a U-shaped function where males with mid-range levels of traits were rated lowest on masculinity. Objective facial analyses revealed that higher levels of autistic traits were associated with less feminine facial structures in females and less masculine structures in males. These results suggest sex-specific relationships between autistic traits and facial masculinity/femininity.     

The Scandal of Deduction

This article provides the first comprehensive reconstruction and analysis of Hintikka’s attempt to obtain a measure of the information yield of deductive inferences. The reconstruction is detailed by necessity due to the originality of Hintikka’s contribution. The analysis will turn out to be destructive. It dismisses Hintikka’s distinction between surface information and depth information as being of any utility towards obtaining a measure of the information yield of deductive inferences. Hintikka is right to identify the failure of canonical information theory to give an account of the information yield of deductions as a scandal, however this article demonstrates that his attempt to provide such an account fails. It fails primarily because it applies to only a restricted set of deductions in the polyadic predicate calculus, and fails to apply at all to the deductions in the monadic predicate calculus and the propositional calculus. Some corollaries of these facts are a number of undesirable and counterintuitive results concerning the proposed relation of linguistic meaning (and hence synonymy) with surface information. Some of these results will be seen to contradict Hintikka’s stated aims, whilst others are seen to be false. The consequence is that the problem of obtaining a measure of the information yield of deductive inferences remains an open one. The failure of Hintikka’s proposal will suggest that a purely syntactic approach to the problem be abandoned in favour of an intrinsically semantic one.     

获得性阅读障碍的“主要系统”假说

认知神经心理学为阅读机制的探讨提供了大量的证据,认为不同阅读障碍是不同加工通道选择性受损的结果。近年来,基于联结主义的三角模型理论,研究者提出了主要系统假说（primary system hypothesis）,认为阅读障碍是主要的认知系统（如视觉、语义和语音系统）受损导致的：表层障碍是因为语义系统受损导致的阅读困难,语音和深层障碍是语音和语义系统同时受损时综合症状的连续体。该理论认为各主要系统可能同时是多个认知活动的加工成分,一个系统的受损会影响所有与之相关的认知过程,从而把阅读障碍与其它认知功能障碍联系起来。统一的主要系统受损下对各种获得性阅读障碍形成机制在文中得到详细的解释
