面孔可信度评价调节：经验迁移假说的提出与验证

面孔可信度评价对人际信任和合作行为有重要影响。以往研究发现面部特征、背景环境等附加信息能通过自下而上、自上而下两种方式调节人们对他人面孔可信度的评价, 但具体的起效和失效机制尚不清晰。针对这一问题, 本文提出了“经验迁移假说”, 并对两类调节方式的认知机制、经验迁移的边界条件和调节过程进行探究。本研究为深化理解人际信任的调控机制提供理论和实证依据。     

“Plateau”-related summary statistics are uninformative for comparing working memory models

Performance on visual working memory tasks decreases as more items need to be remembered. Over the past decade, a debate has unfolded between proponents of slot models and slotless models of this phenomenon (Ma, Husain, Bays (Nature Neuroscience 17, 347-356, 2014). Zhang and Luck (Nature 453, (7192), 233-235, 2008) and Anderson, Vogel, and Awh (Attention, Perception, Psychophys 74, (5), 891-910, 2011) noticed that as more items need to be remembered, “memory noise” seems to first increase and then reach a “stable plateau.” They argued that three summary statistics characterizing this plateau are consistent with slot models, but not with slotless models. Here, we assess the validity of their methods. We generated synthetic data both from a leading slot model and from a recent slotless model and quantified model evidence using log Bayes factors. We found that the summary statistics provided at most 0.15 % of the expected model evidence in the raw data. In a model recovery analysis, a total of more than a million trials were required to achieve 99 % correct recovery when models were compared on the basis of summary statistics, whereas fewer than 1,000 trials were sufficient when raw data were used. Therefore, at realistic numbers of trials, plateau-related summary statistics are highly unreliable for model comparison. Applying the same analyses to subject data from Anderson et al. (Attention, Perception, Psychophys 74, (5), 891-910, 2011), we found that the evidence in the summary statistics was at most 0.12 % of the evidence in the raw data and far too weak to warrant any conclusions. The evidence in the raw data, in fact, strongly favored the slotless model. These findings call into question claims about working memory that are based on summary statistics.

Effectiveness Evaluation of Search and Target Acquisition Training Prototype Using Performance Metrics With Eye-Tracking Data

Despite the increased use of sensor technologies, including unmanned vehicles, the vast majority of improvised explosive device (IED) detections are made by human vision. Thus, TRAC-Monterey developed a simulation-based training prototype called the perceptual learning trainer (PLT). Fourteen novice and 5 expert IED detectors participated in human-in-the-loop experiments in which all participants were trained using the PLT tool while their eye-movement and IED detection performance were tracked in real-time. A series of 100 IED images with various degrees of difficulty was used for the training session. Pre- and posttraining assessments were conducted. Both speed and accuracy improved after just 1 session of the PLT training: RT decreased by 3.7 s for novices (p < .001) and 3.4 s for experts (p = .031), and detection probability increased by 5.9% for novices (p = .001). The PLT tool improved IED detection performance more in novice IED detectors than in experts. Novices and experts showed different visual scan patterns.     

社会主义核心价值体系的内涵及践行

社会主义核心价值体系作为我们党理论创新的重大成果,是我们党进一步加强社会主义和谐文化建设、巩固社会和谐方面的重要举措,进一步加深了我们对中国特色社会主义本质的认识,在新的时期全面推进中国特色社会主义伟大事业,具有重大而深远的意义.本文从哲学观照的角度,论述了其与"科学社会主义"一脉相承的逻辑基础,分析了其"有机统一"的系统结构,从其基本内容的四个方面进行了内涵解读,并就社会主义核心价值体系在思想认识、丰富发展、氛围营造、实事求是四个方面的践行要求给出了浅见.     

哲学思想为医学生创新思维提供启思与导向

创新能力与哲学素养直接相关,创新思维是哲学素养的运用和拓展。目前,医学思维能力培养中存在极大限制医学生想象力和创造力的问题,一是受权威迷信的束缚,二是受传统思维框架的束缚。基于此现状,本研究探讨培养医学生创新思维能力应采取的对策与措施,体现了哲学思想对医学生创新思维的启思与导向作用。     

消化性溃疡中医治疗的思路与方法

消化性溃疡的中医病机为本虚标实,虚、瘀、毒为其最基本的病理特点,治疗应抓住虚、瘀、毒的病理实质,采取健脾和胃补虚、活血通络止痛,解毒导滞和胃的治疗方法,并结合脾胃脏腑的功能特点,灵活运用调达肝木、升清降逆之法以调畅脾胃的功能,从而达到治愈消化性溃疡的目的.     

公共选择中的公正与效率——公共支出隐含的一个悖论

公共支出的决定程序、运用与来源以及内在的价值取向上,都存在着公正与效率的矛盾,这无疑会影响到公共支出对经济增长的拉动作用.若要兼顾公正与效率以及调和公共支出内在的逻辑矛盾,便需要确定更有效的标准和选择合适的规则,降低交易成本和信息不时称的程度,以更透明的程序和更兼顾社会民众的方式,实现由功能财政向公共财政和民主财政的转变,以此提高积极财政政策的作用效率.     

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。     

Vision and Mission Statement in Christian Higher Educational Management in Eastern Africa

For the past two decades, Syrio-Palestine/biblical archaeology is known to have gradually disappeared from American colleges. Nonetheless, this issue has rarely been studied and addressed using quantitative and empirical data. In this paper, the past and present of Syrio-Palestine/biblical archaeology in American colleges are diagnosed by examining the archaeology curricula in American colleges. This study indicates that although it may not be moribund, Syrio-Palestine/biblical archaeology is invisible in many colleges. This paper also shows that Syrio-Palestine/biblical archaeology has been traditionally part of biblical studies in the United States, and it may continue to be so in the future. Hence, one potential avenue to revive Syrio-Palestine/biblical archaeology seems to lie in the integrative approach to archaeology and biblical studies.
