Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources. 相似文献

The Asymptotic Classification Theory of Cognitive Diagnosis (Chiu et al., 2009, Psychometrika, 74, 633–665) determined the conditions that cognitive diagnosis models must satisfy so that the correct assignment of examinees to proficiency classes is guaranteed when non‐parametric classification methods are used. These conditions have only been proven for the Deterministic Input Noisy Output AND gate model. For other cognitive diagnosis models, no theoretical legitimization exists for using non‐parametric classification techniques for assigning examinees to proficiency classes. The specific statistical properties of different cognitive diagnosis models require tailored proofs of the conditions of the Asymptotic Classification Theory of Cognitive Diagnosis for each individual model – a tedious undertaking in light of the numerous models presented in the literature. In this paper a different way is presented to address this task. The unified mathematical framework of general cognitive diagnosis models is used as a theoretical basis for a general proof that under mild regularity conditions any cognitive diagnosis model is covered by the Asymptotic Classification Theory of Cognitive Diagnosis. 相似文献

康德实践理性的事实概念指的是道德律或道德律的意识,而道德律本身实际上是道德律的意识。道德律是某种自身肯定的东西,它作为事实肯定了纯粹实践理性的客观实在性,并通过理性的这一积极的概念,证明了它自身在实践上的客观实在性。正是通过道德律这一事实,在思辨哲学那里只具有消极性的自由的原因性的概念,在实践哲学中获得了积极的规定,也成为了一个“事实”。 相似文献

The Quadratic Relationship Between Body Mass Index and Suicide Ideation: A Nonlinear Analysis of Indirect Effects 下载免费PDF全文
Kelly L. Zuromski MS Ian Cero MA Tracy K. Witte PhD Peng Zeng PhD 《Suicide & life-threatening behavior》2017,47(2):155-167
A nonlinear indirect effects framework was used to investigate potential interpersonal indirect effects (i.e., perceived burden and thwarted belonging) accounting for the nonlinear relationship between body mass index (BMI) and suicide ideation. Using a sample of 338 undergraduates, results revealed a significant quadratic effect of BMI on suicide ideation via perceived burden only, which became significant as BMI fell below 18.00 kg/m2 and above 28.00 kg/m2. Our results provide novel information relevant for suicide risk screening in the context of weight‐ and health‐related interventions and provide justification for future longitudinal trials assessing suicide risk across the BMI spectrum. 相似文献

In an experiment with 80 participants in China, protagonists with opposing views in organizations that valued collectivism, compared to individualism, were found to develop cooperative goals, were confident that they could work, sought to understand, and demonstrated that they understood the opposing arguments, accepted these arguments as reasonable, and combined positions to create an integrated decision. The inductions comparing participants who valued harmony as a goal or a technique in which they pretended to agree were only partially effective and did not yield significant differences on conflict dynamics and outcomes. Findings challenge traditional theorizing that collectivistic values lead to conflict avoidance, and support recent arguments that strong, cooperative relationships promote the productive discussion of opposing views in decision making. 相似文献

This essay explores the history of studies in analytical philosophy in China since the beginning of the last century, by dividing
into three phases. It shows that, in these phases, analytic philosophy was always at a disadvantage in confronting serious
challenges coming from both Chinese traditional philosophy and modern philosophical trends. The authors argue that Chinese
philosophers have both done preliminary studies and offered their own analyses of various problems as well as some new applications
of analytic philosophy especially in the latest period. Meanwhile, Chinese traditional philosophy was always trying to adjust
its cultural mentality in the struggle with analytic philosophy, and accommodated in its own way the rationalistic spirit
and scientific method represented in analytic philosophy. 相似文献
