“鬼妻”事件引起的思考

最近,时见报端及因特网有关娶"鬼妻"或配阴婚(所谓娶"鬼妻"或配阴婚,就是为死亡的单身男子配一个女人,双方以夫妻名义合葬)在一些农村地区盛行的报道,让人感到不安。     

Relations of perceived motivational climate and feelings of belonging in physical education in urban schools

The current pilot study examined the relationship between feelings of belonging and perceptions of motivational climate in physical education classes among 87 African-American, inner-city high school students (41 boys, 46 girls). Motivational climate was assessed by the Perceived Motivational Climate Questionnaire and feelings of belonging were assessed by the Belonging Scale. Contrary to the hypothesis, scores for both the task- and ego-involved subscales of the Perceived Motivational Climate Questionnaire had moderate positive correlations with scores on the Belonging Scale, indicating the relationship between these specific motivational climates and social-emotional outcomes in physical education is not clear and direct. Further research is warranted to assess these findings and to identify what experiences and instructional strategies are most effective in promoting social-emotional outcomes in physical education in urban schools.     

Spatial accuracy demand in aiming movements: kinematic analysis of subtended angle and tolerance width

Subtended angle has been assumed to be an important factor in both response programming time and kinematic characteristics of aiming movements. Support for this assumption has come mainly from studies in which circular targets have been used. However, with circular targets, the subtended angle covaries with the size of the target in the principal direction of the movement (tolerance width). The purpose of this study was to examine the effects of tolerance width and subtended angle on aiming movement with multiple targets. Participants first hit a 5-cm-diameter circular target located 8 cm to the left of a starting position and then moved another 8 cm left to hit either a 5-cm diameter circular target or a 5- x 1-cm rectangular target oriented either horizontally or vertically, depending on the condition. Analysis showed that reaction times and movement times were longer for the vertical rectangular target, which had a smaller tolerance width than the other two targets. In addition, the vertical rectangular target also showed a greater percentage of secondary-submovement trials, lower movement velocity, and higher peak vertical displacement. Overall, the results indicate that the tolerance width of the target may impose more constraints on aiming movements than subtended angle.     

青少年自我意识的功能结构及测评的研究

研究者认为自我意识是个体对自己及与周围环境的关系诸方面的认识、体验和调节的多维度、多层次的心理功能系统;并参考国内外相关的自我意识理论和量表,以城市中学生为被试,经过三个步骤,采用《青少年自我意识量表》,对青少年自我意识的心理结构进行了探索性和验证性研究。研究结果表明：青少年自我意识的功能结构基本可以分为三个维度八个因素（即体貌评价、能力评价、品德评价、自尊感、自信感、自觉性、情绪自控、自制力与坚持性）;自编《青少年自我意识量表》包括个人因子共38个项目;该量表的内部一致性信度和分半信度比较高,也具有较好的结构效度。     

视觉搜索中空间不对称性的眼动研究

采用视觉搜索任务对33名大学生在不同视野中目标搜索过程的眼睛运动进行记录,以探讨不同视野位置的视觉搜索的差异性。研究结果表明,视觉搜索存在明显的空间不对称性,它主要体现在左右视野之间的差异上,具体表现在搜索反应时、平均注视时间以及眼睛跳动等方面。视觉搜索中存在很强的策略,其中主要为水平搜索或垂直搜索,因此,长期的练习和习惯也将影响视觉搜索过程。     

视野位置及刺激特征对目标搜索影响的眼动研究

在视觉搜索中,注意受多种因素的影响。本研究控制了刺激呈现的3种视野位置,旨在研究在不同视野位置上,各种因素发挥作用的情况。要求被试在4个项目中搜索某一特定的靶子,记录了反应时和多种眼动指标。结果发现,在不同的视野位置上,视觉搜索过程受目标状态和刺激特征的影响程度发生了变化。并且对形状和颜色特征的加工存在时间和加工位置上的差异。     

基于分化/整合视角的自尊结构与心理调适的关系

研究采用中介性调节分析策略,探讨了大学生外显自尊、内隐自尊、自我概念清晰性和抑郁的关系.研究发现:外显自尊与抑郁呈显著负相关.内隐自尊调节着外显自尊和抑郁的关系;外显自尊与自我概念清晰性呈显著正相关,内隐自尊调节着外显自尊和自我概念清晰性的关系;外显自尊×内隐自尊对抑郁的效应是通过自我概念清晰性这一中介变量实现的.     

基于小样本容量的IRT参数估计方法比较研究

目前IRT参数估计方法的研究大多数都是基于大样本容量,而基于小样本容量的IRT参数估计方法的研究较少。通过对IRT参数估计方法的比较分析给出了基于小样本容量的IRT参数估计方法。实验数据表明,恰当的估计方法（如改进初值的BP神经网络）能大大提高小样本的参数估计精度。     

佛教的出世思想

出世间是佛教的终极追求,它不是指离开人生社会躲入深山古寺的空间意义,而是透彻地把握世间的实际性质,去除杂染增长清净而至于圆满境地,即世间本身而获得出世间的意义,其具体过程即进入、改革、进善、发达、觉悟人生社会的过程.     

图形的信息编码与表征

图形的信息加工有别于其他视觉信息,主要体现在编码与表征两个方面。图形信息的编码方式和编码时间取决于图形的特征及其复杂性,在此基础上,研究者们分别提出了细节编码模型和范畴编码模型。图形信息表征的几种水平反映了图形信息的编码特性。图形的颜色和形状既可以联合表征,也可以分开表征,这取决于任务的要求。图形其他特征的表征形式还有待于进一步研究。
