“多少”概念发展的研究

采用数量判定任务,分别用2～30和5～100范围内点子图为刺激,研究个体“多”和“少”概念的发展。结果发现：在5～100点子条件下,随年龄的增长,个体“多”概念的判断值、“少”概念的判断值、“多”“少”概念的临界值均显著增大;7～9岁是个体“多少”概念发展的转折期;个体对“多少”概念的认知具有相对性;在本实验的两种条件下,随年龄增长,个体“多”概念的判断值、“少”概念的判断值、“多”“少”概念的临界值逐渐趋于刺激点子数最大值的2/3、1/3、1/2,“多”概念与“少”概念判断的不确定距离逐渐趋于刺激点子数最大变化范围的1/3或略小于1/3。     

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。

Quasicrystalline Al-Fe phase formed by ion mixing

Abstract

A quasicrystalline Al-Fe phase has been formed by room-temperature ion mixing of AI-Fe multiple layers with no additional postannealing. The quasicrystalline phase was dispersed as grain in an amorphous matrix. The size of the grains was about 10-30nm, and the composition was determined to be Al₈₀Fe₂₀. The structure of the quasicrystalline phase was identified by calculating some 20 sharp diffraction rings in the selected-area diffraction pattern and found to be similar to that of the rapidly quenched AI-Mn quasicrystalline phase.     

Effects of crystallization on corrosion resistance and electron work function of Zr65Al7.5Cu17.5Ni10 amorphous alloys

The effects of crystallization on the electron work function and corrosion resistance of Zr₆₅Al_7.5Cu_17.5Ni₁₀ amorphous alloys have been studied. The single-phase amorphous alloy exhibits a better corrosion resistance and has a higher work function than the partially and fully crystallized alloys with the same composition. The close relationship between corrosion resistance and work function indicates that the Kelvin probe technique can be a powerful tool for characterizing the corrosion behaviour of amorphous alloy on an electronic level.     

Discontinuous precipitation initiated at interphase boundaries in a Zn-rich Zn-6.3 at.% Ag alloy

Discontinuous precipitation in a two-phase Zn-rich Zn-6.3at.%Ag alloy has been studied. It has been shown that the eta/epsilon interphase boundaries have the ability to initiate discontinuous precipitation as do the eta/eta grain boundaries. The back-polishing method is used to show the interconnection between a discontinuous precipitate colony and the eta/epsilon interphase boundary. The reaction front velocity of discontinuous precipitation initiated at the eta/eta grain boundary is 12-90% higher than that of discontinuous precipitation initiated at the eta/epsilon interphase boundary under various ageing temperatures.     

The Process Mechanisms Linking Recruiter Positive Moods and Organizational Attraction

The main purpose of this study is to investigate the mechanisms through which recruiters' positive moods lead to organizational attraction. Participants consisted of 161 applicant–recruiter dyads from 55 companies in Taiwan. Results show that recruiters' felt positive moods were positively related to applicant's perceptions of informativeness and competence, which, in turn, influenced organizational attraction. In addition, recruiters felt that positive moods were positively related to their display of positive moods, which were positively related to applicant's positive moods, which, in turn, affected organizational attraction.     

辩证情绪:研究方法及展望

有关辩证情绪的实证研究已经成为情绪研究中的一个新的热点问题,并从一个本土心理学的研究领域演变为主流心理学的研究课题。辩证情绪是指积极和消极情绪的共存。文章对辩证情绪的研究方法进行了回顾,主要包括辩证情绪研究范式的演变、辩证情绪的诱发方法、辩证情绪的测量方法以及辩证情绪的计算方法,并对不同的研究方法的优缺点及其贡献进行了比较和分析。最后,文章对辩证情绪研究方法的未来发展提出了展望。     

元认知在线监控和离线监控与一般元认知能力的关系

该研究探索元认知在线监控和离线监控与一般元认知能力之间的关系,采用跟踪击键任务、学习判断任务和大学生元认知能力量表,对40名大学生进行研究。结果表明:(1)元认知离线监控对一般元认知能力各个子成分的预测作用受元认知在线监控的影响;(2)元认知在线、离线监控对一般元认知能力的预测作用是彼此独立的。     

汉字输入中认知技能与动作技能的分离

通过20名大学生在采用目光注视屏幕上的键盘完成汉字输入任务的眼动研究,将汉字输入中的认知技能与动作技能实现分离,从而探究关于键盘布局图式的认知技能的发展.结果发现:(1)在标准键盘显示下,汉字输入技能水平高分组与低分组在完成时间上没有显著差异,而空白键盘显示下高分组的完成时间显著快于低分组;(2)两种键盘显示方式下,低分组的眼动指标都没有显著差异,而高分组在空白键盘显示下的平均注视时间要显著多于标准键盘显示下的.
