小学几何教学中计算机不同应用模式的比较

计算机应用于教育存在两种常见模式：工具模式和辅导者模式（ＣＡＩ）。该文综合了国内外关于这两种模式教学效果的理论和实证研究,设计出以画笔为工具软件的合作工具模式和合作ＣＡＩ,进行了为期一周的几何教学研究。研究采用前后测准实验设计考察不同应用模式在几何知识和推理能力方面的教学效果,以问卷调查和访谈法考察学生和教师的态度与动机,作品分析法考察学生的学习过程。实验结果表明：①合作工具模式在几何知识和推理能力方面的教学效果显著优于合作ＣＡＩ,并能有效培养学生积极的学习态度;②恰当的教学方法能大大提高工具模式的有效性;③表征的特征能影响学生的认知建构过程。     

光标显示模式对视线交互绩效与用户体验的影响研究

显示与反馈方式是人机交互的重要设计要素。在视线交互这种自然人机交互技术中,视线光标的呈现方式一直是研究的焦点。本研究选取基于凝视点击范式的文本输入任务,设计了2（有无视点锁定功能）×2（有无实时注视点）被试内实验,探讨光标显示模式对视线交互绩效与用户体验的影响。结果：视点锁定功能可以提升交互绩效和用户体验,有无实时注视点对交互绩效无显著影响;输入速度的提升主要在于视点锁定功能能够让被试的视线更快地转移到下一个目标上。研究结果可为视线光标的设计与应用提供借鉴。     

A Review of Sensory Imagery for Consumer Psychology

This review of mental imagery research has the core objective of fostering more research on the topic of sensory imagery. The review is organized around a conceptual framework highlighting (a) how mental imagery is formed, (b) the elicitation and elaboration of mental imagery, (c) the multi-modal nature of sensory imagery, and (d) the consumer behavior consequences of mental imagery. This conceptual framework provides many new lenses through which researchers can view prior findings, and thereby motivates innovative new research ideas. Future research directions are provided in each section of the review, with additional unexplored opportunities presented in a final section.     

心率变异性在心身疾病和情绪障碍研究中的应用

心率变异性的频谱成分可单独反映交感神经和副交感神经活动的影响。高频（HF）是由迷走神经单独介导；低频（LF）受迷走神经和交感神经共同调制，但主要反映交感神经的活动性 。此指标可对高血压、冠心病和月经前期烦躁等心身障碍进行评价。该文还探讨了它用于情绪研究的价值，并认为在不同情绪体验期间的自主神经活动有多种搭配模式，正常人与情绪障碍者之间以及情绪障碍（抑郁、焦虑、恐怖、强迫）患者在自主神经活动方面可能存在显著差别     

Corporate sponsorships may hurt nonprofits: Understanding their effects on charitable giving

While prior research suggests that corporate sponsorship can positively affect consumers' perceptions of sponsors, little research to date has investigated the impact of such sponsorships on an individual's willingness to support nonprofits. This paper investigates the psychological processes that underlie whether and how corporate sponsorship impacts an individual's willingness to support nonprofit organizations and suggests that unintended negative outcomes may emerge. Specifically, results from five studies suggest that exposure to sponsorship information can reduce prospective donors' willingness to support a nonprofit because people believe that their individual contributions will matter less. In addition, this research identifies a potential mechanism (i.e., donor-company identification) that can mitigate these negative effects.     

Editorial to the special issue Neuronus

Did you visit the Neuronus conferences in the years 2012 and 2013 in Kraków? If not, then you certainly should have a close examination of this special issue including this introduction to at least have a glimpse of an idea of the highly interesting topics in the field of cognitive neuroscience that were presented at these conferences. If you were there, it is for sure a good choice to focus on this special issue as well, first to refresh your minds (we know our memories are far from perfect), but especially to see what happened with research of the presenters at these conferences.     

Masked constituent letter priming in an alphabetic decision task

Abstract

The experiments presented here were designed to test whether the prior presentation of a letter in a word, nonword or a string of Xs facilitates the subsequent identification of this letter. Using briefly presented masked primes, clear facilitatory constituent priming effects were obtained in an alphabetic decision task (letter/non-letter classification) when prime letters were flanked by Xs, but the effects disappeared or were greatly reduced when the prime letter formed part of a consonant array (nonword primes). Evidence for word-letter constituent priming was also obtained but almost only for word-initial letten. These facilitatory constituent priming effects were strongest when the target letter was embedded in a string of hash marks and occupied the same relative position in this string as the prime letter in the prime string. The mediating role of letter representations in word recognition and the position-specific coding of character arrays are discussed in the light of these results.     

数目及其呈现方式在不同范围内对时间知觉的影响

采用时间比较法,考察数目及其呈现方式对时间知觉的影响。任务中,首先呈现标准时距,此时变化刺激的数目或呈现方式,然后呈现比较时距,被试的任务是判断比较时距比标准时距长还是短。实验1和实验2分别采用1秒内和1秒以上的时间,结果发现： 1秒内的时间加工中,刺激一个一个连续呈现时,小数引起标准时距的低估,大数导致标准时距的高估,而同时呈现时,刺激的数目对知觉到的时间无影响;数目及其呈现方式影响计时的准确性,而对计时的变异性和敏感性无影响。时间在1秒以上,同时呈现和连续呈现条件下,刺激的数目影响知觉到的时间;计时的     

The Endowment—Institutional Affinity Effect

The endowment effect occurs when ownership of a good leads consumers to value the good more than its market value. Students who were given College of Business Administration insignia mugs to keep valued them significantly more than students who were given the same mugs to examine and return (nonendowment condition). The endowment effect also occurred for plain white mugs. Students who were given plain white mugs to keep valued them more than students who were given the same mugs to examine and return. Ownership of insignia mugs not only resulted in the endowment effect but also resulted in an institutional affinity effect: Students provided higher satisfaction ratings with the College of Business Administration than did students endowed with plain white mugs and students in nonendowed conditions. This study demonstrates the impact of the endowment effect on institutional affinity for insignia goods. However, the tandem endowment-affinity effect occurs at the attitude formation stage, not when an attitude has already been formed.     

我国医疗失效模式与效应分析的应用现状及问题

医疗失效模式与效应分析（HFMEA）是目前较为先进的前瞻性预防医疗风险的方法,强调对整个流程潜在医疗风险的量化及“事前预防”。本研究通过文献计量分析发现,国内HFMEA的研究和应用主要集中在护理操作、手术操作、给药流程以及医疗设备管理等方面,尚处于起步阶段,研究论文的数量较少、研究主题多集中在护理风险管理领域且研究方法不够科学。今后应顺应医疗风险管理的趋势,更科学、有效地开展更多HFMEA研究及应用工作,逐步建立健全医疗风险监测和预警机制,提高医疗安全。
