医患关系中医生沟通能力培训模式的研究进展

从医生沟通能力的视角出发，改善医患关系的相关促进技术主要包括线下课程培训和计算机网络技术的实时交互式模拟训练等形式。其中，线下课程培训是当前医生沟通能力提升的主要促进技术，分别以沟通技能培训Comskil模型和真实工作场所中的医生沟通能力培训周期模型作为理论支撑，形成了针对特殊领域的“告知坏消息”沟通培训课程和处方对话培训课程。线下的课程培训因其在培训时间和培训师能力要求方面的局限性，促使了计算机模拟在医生沟通能力训练上的运用，从而形成了基于计算机的实时交互式模拟训练系统。随着科学技术的发展，未来将会有更多的新技术加入到实时交互式模拟训练中来。     

Comparison of Common Amplitude Metrics in Event-Related Potential Analysis

Abstract

Waveform data resulting from time-intensive longitudinal designs require careful treatment. In particular, the statistical properties of summary metrics in this area are crucial. We draw on event-related potential (ERP) studies, a field with a relatively long history of collecting and analyzing such data, to illustrate our points. In particular, three summary measures for a component in the average ERP waveform feature prominently in the literature: the maximum (or peak amplitude), the average (or mean amplitude) and a combination (or adaptive mean). We discuss the methodological divide associated with these summary measures. Through both analytic work and simulation study, we explore the properties (e.g., Type I and Type II errors) of these competing metrics for assessing the amplitude of an ERP component across experimental conditions. The theoretical and simulation-based arguments in this article illustrate how design (e.g., number of trials per condition) and analytic (e.g., window location) choices affect the behavior of these amplitude summary measures in statistical tests and highlight the need for transparency in reporting the analytic steps taken. There is an increased need for analytic tools for waveform data. As new analytic methods are developed to address these time-intensive longitudinal data, careful treatment of the statistical properties of summary metrics used for null hypothesis testing is crucial.     

The conscious awareness of time distortions regulates the effect of emotion on the perception of time

This study examined how the awareness of emotion-related time distortions modifies the effect of emotion on time perception. Before performing a temporal bisection task with stimulus durations presented in the form of neutral or emotional facial expressions (angry, disgusted and ashamed faces), some of the participants read a scientific text providing either correct or incorrect information on the emotion–time relationship. Other participants did not receive any information. The results showed that the declarative knowledge allowed the participants to regulate (decrease) the intensity of emotional effects on the perception of time, but did not trigger temporal effects when the emotional stimuli did not automatically induce emotional reactions that distorted time.     

Psychophysics and the anisotropy of time

In psychophysics, experimental control over the presented stimuli is an important prerequisite. Due to the anisotropy of time, this prerequisite is not given in psychophysical experiments on time perception. Many important factors (e.g., the direction of perceived time flow) cannot be manipulated in timing experiments. The anisotropy of time is a peculiarity, which distinguishes the time dimension from other perceptual qualities.Here I summarize the anisotropy-related differences between the perception of time and the perception of other qualities. It is discussed to what extent these differences might affect results and interpretations in psychophysical experiments. In conclusion, I argue for a ‘view from nowhen’ on the psychophysical study of time perception.     

Combination or Differentiation? Two theories of processing order in classification

Does cognition begin with an undifferentiated stimulus whole, which can be divided into distinct attributes if time and cognitive resources allow (Differentiation Theory)? Or does it begin with the attributes, which are combined if time and cognitive resources allow (Combination Theory)? Across psychology, use of the terms analytic and non-analytic imply that Differentiation Theory is correct—if cognition begins with the attributes, then synthesis, rather than analysis, is the more appropriate chemical analogy. We re-examined four classic studies of the effects of time pressure, incidental training, and concurrent load on classification and category learning (Kemler Nelson, 1984; Smith & Kemler Nelson, 1984; Smith & Shapiro, 1989; Ward, 1983). These studies are typically interpreted as supporting Differentiation Theory over Combination Theory, while more recent work in classification (Milton et al., 2008, et seq.) supports the opposite conclusion. Across seven experiments, replication and re-analysis of the four classic studies revealed that they do not support Differentiation Theory over Combination Theory—two experiments support Combination Theory over Differentiation Theory, and the remainder are compatible with both accounts. We conclude that Combination Theory provides a parsimonious account of both classic and more recent work in this area. The presented data do not require Differentiation Theory, nor a Combination–Differentiation hybrid account.     

客体和空间工作记忆中三维图形的特征加工时程

采用单探测变化觉察范式，对三维图形的特征在客体和空间工作记忆中的加工时程进行了探讨。实验一的材料是由不同颜色和形状组成的规则立体图形。实验二的材料是由不同颜色和图案组成的六棱柱。实验结果显示：（1）客体和空间工作记忆绩效均随识记项目数的增加而显著下降；（2）随着刺激呈现时间的延长，客体工作记忆绩效显著提高，空间工作记忆绩效无明显增加；且在三种呈现时间条件下，空间工作记忆绩效均高于客体工作记忆；（3）三维图形中颜色特征的检测绩效优于形状、图案和特征捆绑。这些结果表明，视觉工作记忆中三维图形的特征加工存在显著的时程效应，空间位置加工最早完成，其次是颜色加工，然后是形状与颜色-形状的捆绑，最后是图案与颜色-图案的捆绑。     

Time after History: Derrida’s Two Readings of Heidegger

ABSTRACT

The essay situates and dissects Derrida’s two catalytic interventions into Heidegger’s thought on time and history—the seminar Heidegger: The Question of Being & History (1964-5) and the essay Ousia and Grammē (1968). The first aim is to explicate the relation of history to time in Heidegger’s seemingly untroubled passage from a textured and striated temporality into historicity, understood as structured, inscribed, and in a privileged sense, human time. Sustaining the difference of the inseparably intertwined notions of time and history is paramount for Heidegger, yet the place and function accorded to history will mark for Derrida, nothing less than the ultimate impasse of the project of Being and Time. Accordingly, the second aim of the essay is to present and question the productive elision of time and history that Derrida effects through narrative. On the one hand, this elision offers the ground of a forceful critique of the project of Being and Time. On the other hand, this pivotal gesture of deconstruction will always be compelled to seek, through a proliferation of names, those a-temporal and a-historical vanishing points for time and history that undercut the mutual conditioning of the two that it has laboured to effect.
