有时间压力下学习率对学习时间分配议程的影响:来自眼动的证据

利用眼动分析技术,通过设置不同难度和分值的计算项目,探讨了在有时间压力下学习者的学习时间分配。结果发现:(1)在首次项目选择上,学习者优先选择学习率最高的项目;(2)在学习过程中,学习者的项目选择次序也是根据学习率由高到低。总之,在学习时间分配上,如果需要权衡难度与分值,学习者会考虑单位时间的获益,也就是以学习率为议程的主要依据。研究不仅利用眼动分析技术证实了基于议程的学习时间分配模型,而且进一步揭示了学习率是设置学习时间分配议程的重要依据。     

Affect,infrastructure and activism: The House of Brag's London Queer Social Centre in Brixton,South London

The House of Brag was a queer, anti-racist, feminist squatting collective active between 2012 and 2014. This article pieces together an affective and infrastructural geography of the House of Brag's last project: a squatted social centre in Brixton, south London, in the summer of 2014. Drawing on interviews with members of the collective, this article argues that efforts to think and live social and political alternatives – and the affective dimensions of these efforts – cannot be abstracted from their infrastructures. The material space and infrastructure of the squatted social centre, this article contends, shaped the House of Brag's dynamics and work in crucial ways. In foregrounding these issues, this article contributes to literature on geographies of affect, emotions and social movements, in which conflict and ‘negative’ affects and emotions are often minimised, and which largely overlook the complex material geographies of spaces of activism. In exploring a queer, anti-racist, feminist squatted project in 2010s London, this article also contributes to literature on squatting by focusing on a time period, on politics and on locations largely overlooked.     

Task effects reveal cognitive flexibility responding to frequency and predictability: Evidence from eye movements in reading and proofreading

It is well-known that word frequency and predictability affect processing time. These effects change magnitude across tasks, but studies testing this use tasks with different response types (e.g., lexical decision, naming, and fixation time during reading; Schilling, Rayner, & Chumbley, 1998), preventing direct comparison. Recently, Kaakinen and Hyönä (2010) overcame this problem, comparing fixation times in reading for comprehension and proofreading, showing that the frequency effect was larger in proofreading than in reading. This result could be explained by readers exhibiting substantial cognitive flexibility, and qualitatively changing how they process words in the proofreading task in a way that magnifies effects of word frequency. Alternatively, readers may not change word processing so dramatically, and instead may perform more careful identification generally, increasing the magnitude of many word processing effects (e.g., both frequency and predictability). We tested these possibilities with two experiments: subjects read for comprehension and then proofread for spelling errors (letter transpositions) that produce nonwords (e.g., trcak for track as in Kaakinen & Hyönä) or that produce real but unintended words (e.g., trial for trail) to compare how the task changes these effects. Replicating Kaakinen and Hyönä, frequency effects increased during proofreading. However, predictability effects only increased when integration with the sentence context was necessary to detect errors (i.e., when spelling errors produced words that were inappropriate in the sentence; trial for trail). The results suggest that readers adopt sophisticated word processing strategies to accommodate task demands.     

Advocacy,brainwashing theories,and new religious movements

Advocacy by scholars in the field of new religious movements emerged during the ‘cult wars,’ which in the U.S. had their peak between 1970 and 1990 and continued in Europe and Japan in subsequent decades. Advocacy focused on the question of whether the ‘cults’ used a persuasion technique known as brainwashing. The idea of brainwashing was born during the Cold War, and originally applied to Communist techniques of indoctrination, but was lately first extended to religion and subsequently used as a tool to distinguish between legitimate and non-legitimate religions, labeling the latter as ‘cults.’ Prominent psychologists and sociologists were involved in these battles, with most scholars of new religious movements appearing in court in order to criticize the brainwashing theories advocated by psychologist Margaret T. Singer and a handful of anti-cult academics. After the Fishman decision of 1990, which seriously hit the anti-cult camp, advocacy in this field did not disappear but became somewhat less partisan.     

汉字笔画像素数省略对中文句子阅读影响的眼动研究

在前人笔画省略实验的基础上,采用“像素省略”这一更精确的变量操纵来探讨笔画省略对汉字识别的影响。实验采用2（像素省略方式：省前、略后）×3（像素省略水平：15%、30%、50%）被试内设计,分析整句阅读的眼动轨迹。结果显示,像素省略水平越高对阅读的干扰越大,省前条件下对阅读的干扰显著大于略后条件。结果进一步证实了汉字书写顺序对汉字识别的影响,先书写的笔画比后书写的笔画对汉字的识别起到更大的作用,即笔画顺序效应。     

Pure colour novelty captures the gaze

While it is common wisdom that a salient visual event draws attention, experimental research provided mixed support for this hypothesis. The present experiment seeks evidence that a singleton draws attention to the degree that its feature is novel or unexpected. Two visual search experiments were conducted where an irrelevant colour singleton is presented on each pre-critical trial to familiarize participants with the presence of the singleton. In the critical trial of Experiment 1, the singleton was presented in a novel colour without prior announcement. The singleton was gazed at significantly earlier and longer in the critical trial, as compared to pre-critical trials. This result is consistent with predictions from the expectancy discrepancy hypothesis that colour novelty is sufficient to capture attention. Experiment 2 tested the alternative explanation that a surprising event mainly leads to a breakdown of the previously acquired attentional set, which in turn causes a reorientation towards perceptual salience. An unannounced change of the background colour in the critical trial while the singleton colour remained unchanged did not induce an attentional capture by the singleton like in Experiment 1. This result further confirms that surprising events capture attention in a spatial manner.     

The West Bank “Alternative Peace Movement” and its transnational infrastructure: a case study in “primordialist universalism”

This article provides an overview and theorization of the “Alternative Peace Movement” (APM), a transnational education and advocacy network based in the West Bank. Emerging in the troubled context of current Israel-diaspora relations and US campus politics, the APM promotes a syncretic Jewish identity narrative and boundary-crossing political programme. Drawing on a content and discourse analysis of the movement’s online documentation, as well as interviews with movement leaders, participants, and allies, the article outlines the APM’s infrastructure and discourse, and provides an historical backdrop and set of theoretical tools for rendering comprehensible the movement’s seeming contradictions and incoherencies. It describes the APM as a case study in “primordialist universalism,” a political orientation that aims to pursue civic and human rights of a universal character by inhabiting a “hard” ethnonational subjectivity and discursive frame. The concept of primordialist universalism offers social scientists a tool for making sense of hybrid social phenomena that confound traditional categories of political analysis.     

驾驶经验和危险类型对年轻驾驶员危险知觉的影响

结合反应时和眼动测量方法,采用驾驶经验分组2（年轻新手驾驶员,年轻有经验驾驶员）× 危险类型2（明显危险,隐藏危险）的混合实验设计,探索年轻驾驶员危险知觉的经验优势是否随着危险类型的不同而变化。使用一个基于真实交通情境视频的驾驶员危险知觉任务,对27名年轻新手驾驶员和22名年轻有经验驾驶员进行测试,并使用Tobbi T120记录眼动数据。结果发现,总体上,年轻新手驾驶员对潜在道路危险的反应次数比年轻有经验驾驶员更少,反应时间也更慢。两组驾驶员反应时间的差异,随着危险类型的不同而来源于不同的加工阶段。具体来说：一方面,年轻新手驾驶员对明显危险的反应时间慢,是因为他们对该类危险的评估时间长。另一方面,年轻新手驾驶员对隐藏危险的反应时间慢,是因为他们对该类危险的识别时间长。两组驾驶员对危险的平均注视时间受测试中危险类型的影响但不受驾驶经验的影响。这些研究结果表明,在对年轻新手驾驶员进行危险知觉训练或测试时,应重视危险类型对他们危险知觉的影响。     

Higher visuo-Attentional Demands of Multiple Object Tracking (MOT) Lead to A Lower Precision in Pointing Movements

Multiple object tracking (MOT) requires visually attending to dynamically moving targets and distractors. This cognitive ability is based on perceptual-attentional processes that are also involved in goal-directed movements. This study aimed to test the hypothesis that MOT affects the motor performance of aiming movements. Therefore, the participants performed pointing movements using their fingers or a computer mouse that controlled the movements of a cursor directed at the targets in the MOT task. The precision of the pointing movements was measured, and it was predicted that a higher number of targets and distractors in the MOT task would result in a lower pointing precision. The results confirmed this hypothesis, indicating that MOT might influence the performance of motor actions. The potential factors underlying this influence are discussed.
