少数民族大学生文化疏离感调查

本研究在文献综述、谈话、开放式问卷调查的基础上,提出自己关于南部沿海少数民族大学生文化疏离感的理论假设,并在此基础上编制了少数民族大学生文化疏离感的初测问卷,经过初测和相应统计分析,形成正式问卷。最后使用该问卷对八所大学的500名畲族、壮族及其他少数民族大学生的文化疏离感进行调查研究,回收有效问卷398份。探索性因素因素分析结果表明,高职高专学生表现出与本科大学生不同的文化疏离感维度,分别是:文化束缚感、言语疏离感、文化执着感、文化认同感。这表明出地区、民族因素外,被试所接受的教育可能也是影响其疏离感及文化疏离感的重要因素。高职高专学生与大学生所在社会环境,个人特质及心理素质还是有一定的差距。通过方差分析,结果表明,文化疏离感各维度在学历、民族、性别主效应上有显著差异。     

Do you see what I’m singing? Visuospatial movement biases pitch perception

The nature of the connection between musical and spatial processing is controversial. While pitch may be described in spatial terms such as “high” or “low”, it is unclear whether pitch and space are associated but separate dimensions or whether they share representational and processing resources. In the present study, we asked participants to judge whether a target vocal note was the same as (or different from) a preceding cue note. Importantly, target trials were presented as video clips where a singer sometimes gestured upward or downward while singing that target note, thus providing an alternative, concurrent source of spatial information. Our results show that pitch discrimination was significantly biased by the spatial movement in gesture, such that downward gestures made notes seem lower in pitch than they really were, and upward gestures made notes seem higher in pitch. These effects were eliminated by spatial memory load but preserved under verbal memory load conditions. Together, our findings suggest that pitch and space have a shared representation such that the mental representation of pitch is audiospatial in nature.     

痛成分的心理学研究

<正> 近年来.疼痛原理的研究有了迅速的发展,最近提出了针刺对痛的不同成分的影响问题。关于痛的问题,至今尚没有它的科学定义。十九世纪以前,有人把痛看作是紧密地和不愉快的情绪相联系的;自本世纪以来,痛是感觉的观点占了优势。人们都承认痛不同于视、听等感觉,因为它还带有明显的情绪色彩。心理学和生理学教科书中,一方面说痛     

强迫症的脑功能障碍

近期,对强迫症(OCD)的现象学解释强调了病人在特定情境下错误识别和情绪与动机功能的异常加工。来自神经解剖、神经生理以及近期神经心理和功能成像等的相关研究证据显示：OCD病人眶额皮层（OFC）、前扣带回皮层（ACC）的过度激活可能会导致错误识别功能和对行为结果预期的情绪与动机评价增高;背外侧前额皮层(DLPC)的活动减弱损害了对信息加工的认知整合能力。以上这些皮层信号在控制行为活动程序的尾状核进行整合。OCD病人的强迫性观念和行为可能由这些结构相关的神经网络中一个或多个环节的功能障碍所致     

Aiming at Happiness: How Motivation Affects Attention to and Memory for Emotional Images

Socioemotional Selectivity Theory (Carstensen, L. L., Isaacowitz, D. M., & Charles, S. T. (1999). American Psychologist, 54, 155–181) posits that older adults, and anyone else who perceives their time as limited, show a motivational shift toward emotion regulation which causes them to exhibit a positivity bias and negativity avoidance in attention and memory. We tested whether such a motivational shift can indeed cause changes in emotional processing by manipulating motivation in a sample of young adults. After the manipulation, participants looked at real-world images while their eye movements were tracked. It was found that participants motivated to regulate emotion attended less to negative than positive images and showed less looking time to all stimulus types compared to the other two conditions. No evidence was found linking the motivational manipulation to emotional memory.

对三维心理旋转操作任务特性的效应的初步研究

在认知心理学领域,对心理旋转的研究主要是以反应时范式为基础。本研究试图突破反应时范式,把心理测量学和实验的方法相结合,以现代测量理论——项目反应理论的项目参数（如项目难度、区分度、猜测参数）为指标,对心理旋转测验中,操作任务的若干特性对测验项目特性的影响进行研究,结果发现：对于以Ｓｈｅｐａｒｄ三维旋转材料编制的心理旋转测验、测验材料的复杂程度,标准图形和匹配图形的角度差,以及匹配图形的编排位置等对测验项目的诸特性均无显著影响。     

Self‐esteem and culture: Differences in cognitive self‐evaluations or affective self‐regard?

Although people from East Asian countries consistently report lower self-esteem than do those from Western countries, the origins of this difference are unclear. We conducted two studies to illuminate this issue. Study 1 found that Chinese participants appraised themselves less positively than American participants on a cognitive measure of self-evaluations, but cultural differences were absent on a measure of affective self-regard. Moreover, cultural differences in global self-esteem were eliminated once cognitive self-evaluations were statistically controlled. Study 2 found that cultural differences in modesty underlie cultural differences in cognitive self-evaluations. These findings suggest that Chinese feel as positively toward themselves as Americans do, but are less inclined to evaluate themselves in an excessively positive manner.     

面孔信任评价及其与信任倾向的关系

68名大学生对随机生成的300张面孔进行是否值得信任的评价,结果显示评价者对陌生面孔的初始信任程度不同,表明由结构特征所决定的面孔可信度的高低直接影响了评价者对其信任程度的高低。随后研究进一步考察了信任倾向与面孔信任评价间的关系,结果表明信任倾向与面孔信任评价间存在显著正相关,其中在"不值得信任面孔"评价中表现尤为显著。这些结果表明,面孔可信度和信任倾向两因素对于初始信任判断具有重要的影响作用。     

Role of surface roughness in hysteresis during adhesive elastic contact

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) versus indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments which show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P–h curves are not unique.
