当前阅读研究中眼动指标述评

文章重点介绍了阅读研究中常用的眼动指标,它们包括注视时间、眼跳、回视和瞳孔直径等,从字和区域这两个方面探讨了这些眼动指标所反映的认知加工过程,以及选择这些指标时应该注意的问题。最后对眼动指标的选择和使用等问题提出了几点看法。     

流行音乐对中学生的影响及疏导

流行音乐以其独特的旋律、强烈的时代感吸引着一代代中学生,并随风潜入,润物无声地影响着他们的成长和发展。流行音乐已融入中学生的日常生活,也必定在潜移默化中影响着他们的观念和行为方式。因此,必须重视流行音乐对中学生的影响,并采取积极有效的措施发挥流行音乐的正功能,为中学生的成长和发展营造一个良好的文化氛围。     

监狱警察应对方式与心理健康水平研究

本文通过对重庆市监狱警察应对方式和心理健康水平的抽调研究,发现调查对象倾向于采取成熟的应对方式,且其心理健康水平优于普通人群,在对应对方式有效性的评价（认识）、采取的应对方式（行为）和心理健康水平（结果）三者之间存在一致性;男女狱警在应对方式和心理健康水平方面都存在一些差异,且差异显著。这提示我们在进行应对方式干预时要注意男女狱警不同的两性特征和角色期望。     

大学生利他动机的调查研究

研究的主要目的是对大学生利他动机进行调查分析。测量工具为利己性利他动机量表和利他性利他动机量表。被试取自北京5所高校的大学生1920名。结果显示：57.4%的大学生报告高度利己性利他动机。63.2%的大学生报告高度利他性利他动机。性别、独生子女、家庭地点等因素均同大学生利己性利他动机无关。独生子女、家庭地点、学校性质同大学生利他性利他动机有显著关系。     

Experimental and simulated grain boundary groove profiles in tungsten

Grain-boundary grooving has been studied on polished surfaces of polycrystalline tungsten annealed at 1350°C. Atomic force microscopy images were taken in the same area for each groove after different annealing times. Secondary oscillations next to the main groove maxima (predicted for grooving by surface diffusion) were observed, to our knowledge for the first time. The agreement between experimental and calculated groove profiles (using the surface diffusion model of Mullins (1957, J. appl. Phys., 28, 333)) improved when grain-boundary fluxes were introduced.     

Effect of aspect ratio on the compressive deformation and fracture behaviour of Zr-based bulk metallic glass

The compressive deformation and fracture features of Zr₅₉Cu₂₀Al₁₀Ni₈Ti₃ bulk metallic glassy samples with aspect ratios in the range of 0.67–2.00 have been investigated. The compressive plastic strain of the glass monotonically increases with decreasing aspect ratio, but the maximum strength almost maintains a constant value of 1.77–1.88?GPa. All the compressive shear-band angles are equal to?～40° if modified by the rotation of the primary shear bands.     

Understanding scale-dependent yield stress of metals at micrometre scales

The mechanical softening behaviour of micrometre-scale metals (free-standing metal foils and wires) with decreasing either the geometrical or the microstructural scale (i.e. the smaller, the weaker) has recently been reported. Here, we present a mechanism-based model to understand the softening behaviour, which is based on competition between the effects of surface grain relaxation and the interior grain strengthening effect. The model describes well the yield stress of Cu foils with different ratios of the thickness to grain size.     

Confidence in accuracy moderates the benefits of retrieval practice

ABSTRACT

The effect of Retrieval Practice refers to the phenomenon that taking a practice test is more effective for learning than re-study, probably due to the benefit from processes underlying successful retrievals during practice. However, it is rarely studied whether other processes (e.g., metacognitive monitoring) during retrieval practice may also play an important role. In two experiments, we examined whether the effectiveness of retrieval was affected by subjects’ confidence in their retrieval success. Subjects studied word-pairs and rated their confidence after each practice test trial (cued-recall in Exp.1, multiple choice in Exp.2), or re-study trial. In both experiments, we observed the classic retrieval practice effect. Moreover, in Exp.2, the benefits differed as a function of subjects’ confidence in their retrieval performance: the effect of retrieval practice only emerged for high-confidence trials with higher than 56% confidence. In summary, the retrieval practice only facilitates the retention of correct answers with high confidence.     

《管子》生态伦理思想及其当代启示

《管子》生态伦理思想具有丰富而深刻的内涵,“天人相分”与“天人合一”的天人观,“道为物要”与“德润万物”的伦理观,“人君天地”与“人与天调”的实践观。其深刻的精神理念对我们今天的生态文明建设具有重要的借鉴意义。这些启示我们应从强化生态意识、加强生态制度建设、实施行为生态化建设、坚持生态化修养建设等方面加强生态文明建设。     

情绪作为道德判断的“催化剂”：道德判断中的评价倾向与特异性效应

在不同领域的道德判断中,情绪可能起着“催化剂”的作用。一种特定情绪对应一种核心评价;一种情绪只影响某一道德领域的判断,不同情绪的影响是特异性的;进化心理学和具身认知对道德判断中存在的评价倾向和特异性效应进行了解释。未来研究需要探索评价倾向与特异性效应的内在心理机制。以及进一步探讨文化等第三变量对不同情绪与特定领域道德判断的影响。
