小学低年级学生自我监控与监控他人的发展研究

元认知监控包括自我监控和监控他人。本研究用两个实验分别探讨了小学低年级学生自我监控和监控他人之间的关系及其发展趋势。实验一采用100以内加减法的计算任务,来探讨小学低年级学生的自我监测和监测他人。实验二采用难度不同、分值不同的计算任务,来探讨学生的自我控制和控制他人。研究发现:第一,小学低年级学生的自我监测和监测他人都会以前期任务表现为依据,支持MPT假说。而且,自我监测和监测他人都在二年级表现出了明显的转化和提高。第二,小学低年级学生在监测他人时,逐渐由以自我信息为依据调整到以他人认知状态为依据。第三,元认知控制能力的发展落后于监测能力。二年级和三年级学生仍旧不能很合理地进行自我执行和计划他人。     

Group Ethical Decision Making Process in Chinese Business: Analysis From Social Decision Scheme and Cultural Perspectives

Literature concerning group ethical decision making in a business setting has traditionally focused on directly comparing group versus individual decisions and then investigating differences. Analysis of the interactive process of group ethical decision making appears sparse. This study addresses the gap by investigating group decision making from a social decision scheme (SDS) perspective in a Chinese cultural setting. A cohort of Chinese accountancy students evaluated ethical business scenarios individually and then in a group context. Group responses could be explained in terms of both the SDS and the Chinese cultural perspective (zhongyong). Specifically, groups did not select the most ethical choice but rather the most moderate of all choices advocated by the majority (zhongyong). These results show the application of SDS theory in a culturally specific (Chinese) environment and note the impact of culturally specific factors (zhongyong) on business decision making. The implications are significant for business. If ethical decisions are entrusted to groups, the impact of culturally specific factors must be fully appreciated in evaluating the final decision.     

Visual properties and memorising scenes: Effects of image-space sparseness and uniformity

Previous studies have demonstrated that humans have a remarkable capacity to memorise a large number of scenes. The research on memorability has shown that memory performance can be predicted by the content of an image. We explored how remembering an image is affected by the image properties within the context of the reference set, including the extent to which it is different from its neighbours (image-space sparseness) and if it belongs to the same category as its neighbours (uniformity). We used a reference set of 2,048 scenes (64 categories), evaluated pairwise scene similarity using deep features from a pretrained convolutional neural network (CNN), and calculated the image-space sparseness and uniformity for each image. We ran three memory experiments, varying the memory workload with experiment length and colour/greyscale presentation. We measured the sensitivity and criterion value changes as a function of image-space sparseness and uniformity. Across all three experiments, we found separate effects of 1) sparseness on memory sensitivity, and 2) uniformity on the recognition criterion. People better remembered (and correctly rejected) images that were more separated from others. People tended to make more false alarms and fewer miss errors in images from categorically uniform portions of the image-space. We propose that both image-space properties affect human decisions when recognising images. Additionally, we found that colour presentation did not yield better memory performance over grayscale images.     

短期习得的语言范畴使成人大脑右半球颜色范畴知觉转为左半球颜色范畴知觉

本研究探讨了色词与颜色重组训练能否让被试习得与真实情境相似的色词与颜色范畴联结, 并引起相应的偏侧化颜色范畴知觉, 从而进一步揭示语言编码对颜色范畴知觉的影响。采用六种蓝色作为材料。B1与B2为先前研究的两种蓝色。B11和B12, B21和B22分别为使B1, B2变浅和变深所得, 四者是连续的蓝色。训练被试分别用“duān”和“kěn”命名B1和B2。由于被试可能习得色词与颜色范畴的联结, 因此B12与B21为可能变范畴间颜色, B11和B12, B21和B22为可能变范畴内颜色。训练前后分别让被试完成一个视觉搜索测验。结果发现：前测中可能变范畴间颜色的辨别优于可能变范畴内颜色, 且在左视野呈现时更显著; 后测中可能变范畴间颜色的辨别同样优于可能变范畴内颜色, 但在右视野呈现时更显著。这提示：(1)人们在知觉同一语言范畴的不同颜色时可能会区分深浅范畴, 并因此引发右半球颜色范畴知觉; (2)短期习得的语言范畴能引起偏左半球颜色范畴知觉, 且使右半球颜色范畴知觉转为左半球颜色范畴知觉; (3)被试在训练中习得了色词与颜色范畴的联结; (4)范畴学习可以在仅学习一个样例的条件下自动发生。     

Executive turnover: the influence of dispersion and other pay system characteristics

Using tournament theory as a guiding theoretical framework, in this study, we assess the organizational implications of pay dispersion and other pay system characteristics on the likelihood of turnover among individual executives in organizational teams. Specifically, we estimate the effect of these pay system characteristics on executive turnover decisions. We use a multi-industry, multilevel data set composed of executives in publicly held firms to assess the effects of pay dispersion at the individual level. Consistent with previous findings, we find that pay dispersion is associated with an increased likelihood of executive turnover. In addition, we find that other pay characteristics also affect turnover, both directly and through a moderating effect on pay dispersion. Turnover is more likely when executives receive lower portions of overall top management team compensation and when they have more pay at risk. These conditions also moderate the relationship between pay dispersion and individual turnover decisions, as does receiving lower compensation relative to the market.

Multidimensional Self-Perception of Sexually Abused Girls: Factor Models and Differences Between Sexual Abuse and Comparison Groups

This study investigated the multiple dimensions of self-perception in a sample of sexually abused and nonabused comparison girls (n = 140), with particular attention to self-perception in the scholastic, social, athletic, physical (appearance), and behavioral conduct domains. First, this study examined whether the five dimensions of self-perception were psychologically discrete. Second, the relationships between the self-perception factors and childhood sexual abuse were investigated using structural equation modeling. The results supported the multidimensionality of self-perception and suggested the presence of two distinct second-order self-perception factors: academic- and social-self. While the sexually abused girls indicated less positive perception for the academic-self than the comparison group, the two groups did not differ regarding the social-self. The findings highlight the importance of a multidimensional approach to self-perception in assessing and treating sexually abused children.

回忆日本军国主义在茅山道院犯下的罪行

今年是世界反法西斯战争胜利60周年,也是中国人民抗战胜利60周年。60多年前,日本军国主义者野蛮侵略中国,被道家誉为“第一福地,第八洞天”的茅山道院也未能逃脱魔爪。1938年农历闰七月初八的傍晚,万恶的日寇初次来到茅山道院的元符万宁宫就大肆烧杀,先用燃烧弹将华丽而高大的三清殿和西斋道院的许多楼房焚烧,又将眼睛不好的守庙居士黎洪春(解放后曾任中国道协会长黎遇航先生的父亲)带走,日寇要他带路上大茅峰,这位出家人不肯助纣为虐,拒绝从命。残暴的日军哪里由他,拖着他走,当他被推拉到华阳洞旁时,恼羞成怒的日军再也没有了耐心,将他和沿…
