自主创新的心理发生机制研究

自主创新是社会、自然和人类自身的发展变化,与一个国家或企业原有发展水平之间的矛盾所产生的创新需要向个体身上转化,与个体自我实现的需要相互作用而产生的。一般经过创新需要的形成、转化、现实化,再由创新需要转化为创新动机而引发。可分为有意自主创新和无意自主创新两种类型。     

Restricted Recalibration of Item Response Theory Models

Psychometrika - In item response theory (IRT), it is often necessary to perform restricted recalibration (RR) of the model: A set of (focal) parameters is estimated holding a set of (nuisance)...     

Reception and willingness to share pseudo‐profound bullshit and their relation to other epistemically suspect beliefs and cognitive ability in Slovakia and Romania

Propensity to judge randomly generated, syntactically correct (i.e., bullshit) statements as profound is associated with a variety of conceptually relevant variables (e.g., intuitive cognitive style and supernatural beliefs). Besides generalizing these findings to a different cultural setting, we examined the relationships to sharing the bullshit on social media. Rating nonsense as profound was associated with a lower cognitive ability; a stronger belief in the paranormal, alternative medicine, and conspiracies; and ontological confusion. The more profound a statement was rated to be, the more likely it was to be shared, and propensity for sharing bullshit was predicted by ontological confusion and religious beliefs. Bullshit receptivity and sharing may be closely related to several dimensions of epistemically suspect beliefs; people with these propensities are relatively open to vague statements resembling New Age spirituality.     

Head rotations in the play of Hanuman langurs (Semnopithecus entellus): description and analysis of function

Although head rotations are frequent patterns in play behavior in many mammalian species and differ from head movements used in other contexts, they have not been quantitatively described and their function remains unclear. The head rotations occurring in the play behavior of free-ranging Hanuman langurs (Semnopithecus entellus) were described from videotaped sequences. The authors tested 2 possible hypotheses about their function. Either the head rotations serve to create unexpected situations and should therefore occur in both solitary and social play and also be very variable, or they serve as play signals and should therefore occur only in social play and be ritualized. If head rotations have both functions, they should be less variable in social play. The data revealed that head rotations were very variable and were present both in solitary and social play. Furthermore, there was no difference in the variability between the head rotations present in the 2 types of play. The results do not support the function of head rotations as play signals but, rather, suggest that head rotations may serve to create unexpected situations in play.     

Scale of expectations of control and responsibility: adaptation to the Spanish language and its relation to personal initiative

Personal initiative, understood as a proactive behaviour, self-initiated, persistent and pro-organization, is indispensable in contemporary organizations immersed in an environment of rapid and complex changes and innovations. In this work, one of the antecedents of personal initiative in the work setting is analyzed: the expectations or hopes of control and responsibility. We studied the adaptation to Spanish of the Scale of Expectations of Control and Responsibility of Frese and colleagues, using two cross-sectional samples (n=414 and 396, respectively). We performed exploratory and confirmatory factorial analyses that positively replicate the factor structure of the original scale. The relation of the expectations of control with personal initiative is confirmed, as suggested in the general model of antecedents and consequences of personal initiative. Likewise, the study confirms that control can be considered an antecedent of expectations of control and responsibility.     

Optimism across cultures: In response to the severe acute respiratory syndrome outbreak

Based on our early research, we predicted that the Chinese may be more optimistic and less pessimistic than North Americans in response to negative life events. A survey was conducted to investigate optimism cross culturally in the context of the severe acute respiratory syndrome (SARS) outbreaks in Canada and China. Chinese students in Beijing and European Canadians in Toronto answered questions about their perceptions of SARS. No significant cultural difference was found on dispositional optimism, as measured by the Revised Life Orientation Test (LOT-R). Unrealistic optimism was measured in the context of SARS. Both groups demonstrated unrealistic optimism (i.e. reporting that the self was less likely than an average person to get infected with SARS). Such optimistic bias was stronger among Chinese than among Canadians. Compared to the actual infection rates in Beijing and Toronto, both Chinese and Canadian participants overestimated their own chances of getting infected, indicating that they were being pessimistic. Indeed, Chinese were less pessimistic than Canadians. In addition, even though the Chinese reported more inconvenience brought by SARS than did Canadians, they also reported more positive changes brought by SARS, reflecting the Chinese dialectical views of events. Implications for research on optimism in context are discussed.     

分部评分模型与其它几种多级模型的比较

项目反应理论(IRT)是当前教育与心理测量领域的一个重大进展,也日益成为当今测验领域的一个热点。本文对IRT理论中的二个重要评分模型PCM与GPCM作了简要的介绍。并较详细地对PCM与GPCM模型的逻辑结构及其适用范围进行了论述,指出了它们与其它几种重要模型之间的关系及不同之处。     

中小学生惯用语理解发展的研究

对惯用语理解的发展 ,是儿童语言发展的重要方面。本研究结果表明 ,在无语境条件下 ,中小学生对惯用语的理解年级差异显著 ,小学生和中学生差异较大 ,而小学和中学各年级内部差异不显著。学生对惯用语是先理解字面意义 ,再理解比喻意义。在有语境条件下 ,不同年级学生对惯用语的理解差异显著 ,惯用语语义倾向性的影响不显著 ,但语境对学生惯用语理解有重要影响 ,高年级学生能更好地利用语境。
