Friends on the Margins

In this essay, I examine Richard Miller’s exposition of political solidarity as one of the key contributions of his multifaceted argument in Friends and Other Strangers to the study of religion, ethics, and culture. Miller’s focus on culture broadens the landscape of ethical analysis in ways that illuminate how culture and cultural productions mediate and construct norms and virtues, and the complex relations between self and society. I challenge Miller’s inclination, however, to focus scholarly attention more on habituated forms of civic identity and communal solidarity rather than on disruptive potentialities and critical practices. I suggest that an engagement with social movement theory and the sociology of emotions, with their focus on semiotic analysis and social change processes and mechanisms, can greatly enrich Miller’s account of religion and ethical solidarity.     

Characterization of fine motor development: Dynamic analysis of children’s drawing movements

In this study, we investigated children’s fine motor development by analyzing drawing trajectories, kinematics and kinetics. Straight lines drawing task and circles drawing task were performed by using a force sensitive tablet. Forty right-handed and Chinese mother-tongue students aged 6–12, attending classes from grade 1 to 5, were engaged in the experiment. Three spatial parameters, namely cumulative trace length, vector length of straight line and vertical diameter of circle were determined. Drawing duration, mean drawing velocity, and number of peaks in stroke velocity profile (NPV) were derived as kinematic parameters. Besides mean normal force, two kinetic indices were proposed: normalized force angle regulation (NFR) and variation of fine motor control (VFC) for circles drawing task. The maturation and automation of fine motor ability were reflected by increased drawing velocity, reduced drawing duration, NPV and NFR, with decreased VFC in circles drawing task. Grade and task main effects as well as significant correlations between age and parameters suggest that factors such as schooling, age and task should be considered in the assessment of fine motor skills. Compared with kinematic parameters, findings of NFR and VFC revealed that kinetics is another important perspective in the analysis of fine motor movement.     

正负效价面部表情图片加工的差异

为探讨正负效价面部表情图片识别的差异,采用独立呈现范式呈现正负效价面部表情图片,控制呈现时间和提示线索位置,并利用眼动仪记录识别过程中的眼动指标。结果发现:(1)在识别速度和正确率上,加工积极面部表情图片高于加工消极面部表情图片,显示出积极表情优势。(2)呈现时间没有改变正负效价表情图片加工之间的差异。(3)存在提示线索位置效应,即提示线索在嘴部有利于面部表情识别。(4)面部表情识别遵循"眼部-嘴部-眼部"的规律。结果提示不同性质面部表情的加工机制不同,加工深度作用小于线索作用。     

刺激的视觉显著性和奖赏价值对眼跳的影响

本研究旨在探索刺激的视觉显著性和奖赏价值分别在协同和竞争的条件下对眼跳过程的影响。实验材料为成对的Gabor图案,要求被试选择具有更高奖赏价值的图案,并记录下其眼动过程。实验分为协同条件和竞争条件。结果发现,在不同实验条件下,奖赏价值对眼跳命中率和潜伏期均存在显著效应;视觉显著性的效应则在不同实验条件下出现了分离。刺激驱动过程和目标驱动过程对眼动行为的影响可能是互相区别的两种不同模式。     

中文阅读知觉广度的影响因素研究

研究以Eyelink2000车载眼动仪为工具,采用6×3×2×2的四因素混合设计,借助经典的移动窗口技术,探讨了72名被试阅读知觉广度的发展情况,以及材料难度和阅读能力对知觉广度的影响。结果表明:(1)年级、材料难度、阅读能力均各自独立地影响知觉广度。(2)小学三年级被试知觉广度的右侧范围为1~2个字,小学五年级被试接近成人大学生的知觉广度,右侧范围均为2~3个汉字。(3)难度对知觉广度有影响,被试阅读难材料的知觉广度为2~3个汉字,易材料为2~4个汉字。(4)高阅读能力被试的知觉广度大于低阅读能力被试,阅读容易材料时比低阅读能力被试有更大的向右眼跳幅度。     

听障学生汉语唇读面部加工方式的差异：来自眼动的证据

为探讨高低唇读理解能力听障学生唇读面部加工方式的差异,研究采用视频—图片匹配范式并结合眼动技术,考察高低唇读能力组语前-语中-语后和整体面部加工方式。结果发现,虽然两组都表现出社会协调模式,但高唇读能力组社会协调分数更高,且眼部维持时间更长。表明高唇读能力者整体加工和眼部、口形并行加工能力强,支持凝视假说和社会协调模式;低唇读能力者整体加工效率低,更依赖口形,未能通过补偿策略获得良好的补偿效果。     

The World Council of Churches’ Relationships with Pentecostalism: A Brief Historical Survey and Some Recent Perspectives on Membership Matters

This article approaches the problematic of relationships between the World Council of Churches (WCC) and Pentecostalism, mainly from the perspective of membership of Pentecostal churches in the WCC. It contents a brief presentation of some prejudices regarding Pentecostals in the ecumenical movement and a historical survey of the relationships between the WCC and Pentecostals, as well as a more detailed analysis of the actual status of this relationship from the perspective of membership of Pentecostal churches in the WCC. The last section assesses possible future scenarios in this regard. It is underlined that the Pentecostal movement is already represented in the WCC by a few small Pentecostal churches and that all the debate on whether to accept new Pentecostal member churches in this ecumenical organization should have as its starting point the reality that Pentecostalism is already part of the WCC. After presenting in detail the last debate in the Permanent Committee on Consensus and Collaboration (PCCC) on the issue of the WCC opening the doors to Pentecostal churches, this article concludes that the WCC should follow its previous policy of analyzing individually each application for membership according to its criteria for accepting new members. While most Pentecostal churches would agree with the basis of the WCC and some might increase their ecumenical engagement at all levels, in the near future at least, Pentecostal churches may still have a long way to go to integrate themselves in a genuine ethos and desire for unity.     

教学微视频的播放速度对学习效果的影响

为探究教学微视频播放速度对学习效果和学习满意度的影响,实验1采用行为测试和眼动追踪技术测查了62名大学生在正常播放、1.5倍和2倍播放条件下的学习效果和视觉注意过程。结果表明随着播放速度加快（1）学习者的学习效果和学习满意度会降低;（2）对图片区的注视时间及图文转换次数减少。加速播放视频不利于学习,可能是因为学习时长不同。从现实情境和理论研究两方面考虑,实验2控制了相等的视频学习时长后发现：（1）与正常速度相比1.5倍播放不会抑制学习,2倍播放的学习效果高于1.5倍;（2）但不同速度的学习满意度和眼动结果无显著差异。该研究为短视频播放速度的相关研究提供了新的研究视角,并对教学微视频设计提供了参照。     

解读成语中的他人心理与互动心理：来自眼动和ERP的证据

为了探查理解单个他人心理与解读互动心理的差异机制, 在实验一和实验二中分别采用眼动和事件相关电位技术来测评个体解读中文四字成语中的单个他人心理和互动心理的加工过程。眼动实验发现, 单人成语第二个字的总阅读时间显著长于物理成语; 随后, 互动成语前三字的凝视时间显著长于单人和物理成语。脑电实验发现, 在成语呈现后500~700ms, 解读单人和互动成语诱发的额区晚期正成分(LPC)平均波幅显著大于解读物理成语; 之后在700~800ms, 解读互动成语诱发的额中区LPC平均波幅显著大于解读单人和物理成语。眼动注视模式和脑电证据共同印证了理解单个他人的心理与理解多人的互动心理存在时间和强度上的差异。相对于物理表征和单人心理的加工, 理解更为复杂的互动心理需要更长的加工时间和更强的神经活动。
