键盘操作的工效学研究回顾

对K键盘、分离键盘、TONY键盘、槽式键盘及和弦键盘等的工效特征 (输入效率、肌肉疲劳、EMG特征和主观舒适感 )进行了比较和总结 ,系统地回顾和分析了键盘启动力和听觉反馈等因素对操作者打字力、肌肉活动水平和主观舒适感的影响效应。在总结近几十年相关研究的基础上 ,提出今后应进一步开展键盘启动力、打字速度和反馈方式等方面的研究。     

建筑有学问,风水是迷信

近几年,风水术又流行起来。风水先生不足论,在一些学者的言论和论著中,也把风水说成是建筑选址的“环境科学”,比如要依山傍水,背风向阳之类。笔者经过对历史文献的考察,发现这完全是一种误解。兹将结果发表,供有关人士参考。一、风水术不是孔孟老庄及其以前的传统选择适当的地方做窝,是许多动物的本能。据研究,有些动物还有选择葬地的行为。到该死的时     

教师教学监控能力的结构:一个验证性的研究

根据前期的理论研究,建构出教师教学监控能力的六成分结构,并根据这个结构深入到中小学课堂进行现场观察与访谈,由此形成教师教学监控能力量表的初步项目,再经过预试,初步的项目分析与修订,最终形成量表。

初中一,二年级学生的亲子冲突

本研究选取北京市两所普通中学１９２名初一和初二学生为被试,通过学生对８个方面亲子冲突的评价,探讨初中生亲子冲突的特点。研究发现,（１）初中生早期的亲子冲突处于较低水平;（２）与母亲的冲突多于与父亲的冲突,女生尤其如此;（３）多数亲子冲突随年级而增加;（４）在多数冲突上,男生与父母的冲突多于女生;（５）亲子冲突最多的三个方面为日常生活安排、学业和家务,而冲突最少的为隐私。     

In search of the ‘Aha!’ experience: Elucidating the emotionality of insight problem‐solving

Although the experience of insight has long been noted, the essence of the ‘Aha!’ experience, reflecting a sudden change in the brain that accompanies an insight solution, remains largely unknown. This work aimed to uncover the mystery of the ‘Aha!’ experience through three studies. In Study 1, participants were required to solve a set of verbal insight problems and then subjectively report their affective experience when solving the problem. The participants were found to have experienced many types of emotions, with happiness the most frequently reported one. Multidimensional scaling was employed in Study 2 to simplify the dimensions of these reported emotions. The results showed that these different types of emotions could be clearly placed in two‐dimensional space and that components constituting the ‘Aha!’ experience mainly reflected positive emotion and approached cognition. To validate previous findings, in Study 3, participants were asked to select the most appropriate emotional item describing their feelings at the time the problem was solved. The results of this study replicated the multidimensional construct consisting of approached cognition and positive affect. These three studies provide the first direct evidence of the essence of the ‘Aha!’ experience. The potential significance of the findings was discussed.     

Working memory capacity of biological movements predicts empathy traits

Working memory (WM) and empathy are core issues in cognitive and social science, respectively. However, no study so far has explored the relationship between these two constructs. Considering that empathy takes place based on the others’ observed experiences, which requires extracting the observed dynamic scene into WM and forming a coherent representation, we hypothesized that a sub-type of WM capacity, i.e., WM for biological movements (BM), should predict one’s empathy level. Therefore, WM capacity was measured for three distinct types of stimuli in a change detection task: BM of human beings (BM; Experiment 1), movements of rectangles (Experiment 2), and static colors (Experiment 3). The first two stimuli were dynamic and shared one WM buffer which differed from the WM buffer for colors; yet only the BM conveyed social information. We found that BM-WM capacity was positively correlated with both cognitive and emotional empathy, with no such correlations for WM capacity of movements of rectangles or of colors. Thus, the current study is the first to provide evidence linking a specific buffer of WM and empathy, and highlights the necessity for considering different WM capacities in future social and clinical research.
