Explained Variance and Intraclass Correlation in a Two-Level AR(1) Model

The total variance of a first-order autoregressive AR(1) time series is well known in time series literature. However, despite the increased use and interest in two-level AR(1) models, an equation for the total variance of these models does not exist. This paper presents an approximation of this total variance. It will be used to compute the unexplained and explained variance at each level of the model, the proportion of explained variance, and the intraclass correlation (ICC). The use of these variances and the ICC will be illustrated using an example concerning structured diary data about the positive affect of 96 married women.     

知觉适应对种族融合面孔的种族分类和知觉辨别的影响

面孔加工的种族效应(the other-race effects)指人们对面孔做个体辨别任务时辨别本族面孔的绩效优于辨别他族面孔的绩效, 而做种族分类任务时分类他族面孔的绩效优于分类本族面孔的绩效。本研究通过知觉适应操纵被试对种族两歧(高加索和亚洲)融合面孔的种族知觉, 进而比较被试在两种条件下对同一张融合面孔进行种族分类和知觉辨别的绩效的差异。结果发现, 知觉适应能使被试产生将两歧融合面孔知觉为与原始面孔所属种族相反种族的知觉偏向, 并且, 伴随着这种知觉偏向, 两歧融合面孔的加工出现了他族分类优势和本族辨别优势, 提示社会认知因素对面孔加工的种族效应有重要作用。     

Young children’s developing conception of knowledge and ignorance: work in progress

When do children acquire an understanding of knowledge and ignorance? We analyzed the early development of children’s spontaneous references to knowing and not knowing and conclude that 2-year-olds talk explicitly and cogently about their own knowledge as well as that of an interlocutor. Two-year-olds also admit their own ignorance. Moreover, consistent with their realization that an informant may know what they do not, 2-year-olds ask many information-seeking questions. Finally, we discuss children’s receptivity and skepticism, especially toward the counterintuitive claims of an adult. We conclude that children’s conception of knowledge and ignorance begins early but undergoes protracted refinement.     

ROLES OF EPISTEMOLOGY IN INVESTIGATING KNOWLEDGE: “PHILOSOPHIZING WITH”

Abstract: This article aims at elucidating the ways in which philosophy may engage in cooperation with other disciplines through “philosophy with” ( Hansson 2008 ). An exemplary investigation is undertaken of the roles of epistemology in investigating knowledge, that is, how epistemology may interact with sciences concerned with knowledge. Four possible roles are distinguished: provider of a priori conceptual analyses, clarifier of scientific concepts and their implications, interpreter of scientific results, and dialogue partner with a voice of its own. Each role is illustrated by contemporary texts, and it is argued that the role of dialogue partner is the most fruitful.     

脏腑经络之气互藏理论初探

通过多年临床实践,反复研读<内经>、<伤寒论>、<金匮要略>等经典著作,认为中医理论中有脏腑经络之气互藏理论.分别从五行互藏理论、寸口脉的临床应用、脏腑之气和经络之气及十二经脉与奇经八脉的关系、各脏腑的功能发挥与脏腑经络之气的关系、中医辨证论治的临床应用等五个方面探讨了脏腑经络之气是互藏的理论.     

Trauma,resilience and healthy and unhealthy forms of dissociation

This paper outlines the difference between healthy and unhealthy forms of dissociation following, and in response to, traumatic experience, in particular the experience of refugees, calling on 30 years’ experience in working with refugees in voluntary and public sectors, including 20 years at the Refugee Therapy Centre, London. It differentiates dissociation from repression, and looks at some of the specific traumatic experiences associated with refugees’ displacement and situation, particularly relating to loss. Four key characteristics of resilience are described: ‘psychic space’, ‘sense of self’, and the use of a ‘listening other’ and ‘healthy dissociation/resiliency’. Two vignettes are given to illustrate the difference between healthy and unhealthy dissociation.     

Renewal of operant performance formerly eliminated by omission or noncontingency training upon return to the acquisition context

Renewal of operant performance formerly eliminated by omission or noncontingency training was explored in two experiments with rats. When pressing a lever was trained with food reinforcement in one context (A) and then eliminated in a second context (B), responding was renewed by returning the rats to the original context (A). This ABA renewal effect was demonstrated in Experiment 1 when the elimination training was an omission procedure (delivery of food for withholding responding) and in Experiment 2 when it was a noncontingency procedure (delivery of food irrespective of responding). Because omission training (differential reinforcement of other behavior) and noncontingency training have been used in applied settings as effective procedures to reduce undesired human behaviors, the clinical implications of our findings for the relapse of undesirable behavior were discussed.     

When the self represents the other: a new cognitive neuroscience view on psychological identification

There is converging evidence from developmental and cognitive psychology, as well as from neuroscience, to suggest that the self is both special and social, and that self-other interaction is the driving force behind self-development. We review experimental findings which demonstrate that human infants are motivated for social interactions and suggest that the development of an awareness of other minds is rooted in the implicit notion that others are like the self. We then marshall evidence from functional neuroimaging explorations of the neurophysiological substrate of shared representations between the self and others, using various ecological paradigms such as mentally representing one's own actions versus others' actions, watching the actions executed by others, imitating the others' actions versus being imitated by others. We suggest that within this shared neural network the inferior parietal cortex and the prefrontal cortex in the right hemisphere play a special role in the essential ability to distinguish the self from others, and in the way the self represents the other. Interestingly, the right hemisphere develops its functions earlier than the left.
