电击信号应激对大鼠体液免疫及内分泌功能的影响

研究了足电击及以电击装置为信号刺激所诱发的情绪应激对大鼠原发性体液免疫反应及内分泌的影响。 结果表明每天１０分钟,共６天的足电击对大鼠抗特异性抗原ＯＶＡ的原发性体液免疫反应无明显作用,而此电击作 用结合每天１０分钟,共８天的情绪应激则可显著降低大鼠体液免疫反应及脾脏指数。同时该应激可显著提高大鼠 血儿茶酚胶和皮质酮水平。该研究证明了情绪应激对大鼠体液免疫功能的调节作用,并对交感神经系统和下丘脑－ 垂体－肾上腺（ＨＰＡ）轴在其中所起的作用进行了初步探讨。     

风水问题资料(二)

十三、晁公武论风水术的荒谬——唐顺之《稗编》(选载)按:晁公武是南宋著名学者。他根据郭璞曾经为母亲选择葬地,断定《葬书》就是郭璞所作,理由不足。但他对郭璞命运的评论,却简要而深刻,值得那些迷信风水者深思。今译:     

UFO和声称的绑架事件调查(四)——被外星人绑架

至于被绑架者故事,也并不新鲜。比如,关于仙女被飞龙绑架,后被一个勇敢的剑士救回的故事,就是这样的传说。乡间传说的被绑架者也只不过是每个民族都存在的这种故事的组成部分。骑着巫师的扫把或被仙女用马车带走,也是许多不同民族中流传的民间故事。所以,在我们自己的时代遇到这样的故事也一点都不奇怪。     

What influences children's and adolescents' understanding of the complexity of the Internet?

This study aimed at analyzing complex relationships among Internet use, Internet users, and conceptual understanding of the Internet. It used path models to examine factors related to Internet use (duration of Internet use, frequency of Internet use, and informal Internet classes) and Internet users (age and gender) in affecting understanding of the technical and social complexity of the Internet for 322 elementary and middle school students. The findings of the study indicate that (a) age of young Internet users had predominant effects on both the technical and social understanding of the Internet; (b) frequency of Internet use and informal Internet classes had small but significant effects on social understanding, but no effect on technical understanding; and (c) technical understanding had a unidirectional effect on social understanding. The implications of these findings for the implementation of the Children's Internet Protection Act are discussed.     

Children, adolescents, and the internet: a new field of inquiry in developmental psychology

With this special section on children, adolescents, and the Internet, we survey the state of a new field of inquiry in developmental psychology. This field is important because developmentalists need to understand how children and adolescents live in a new, massive, and complex virtual universe, even as they carry on their lives in the real world. We have selected six empirical articles to showcase various aspects of child and adolescent development in this virtual universe. These articles reflect three major themes of this new field: communication on the Internet; cognitive development, academic achievement, and the Internet; and adolescents in a globalized Internet world. These three sections reflect one of our major editorial goals: to sample various relevant aspects of development as they relate to the Internet. The selection of articles reflects a second editorial goal: to sample both the positive and negative aspects of the virtual world in which children and adolescents are increasingly living. Another of our editorial goals was to sample as large an age range as possible. We also utilized a very broad definition of development. Last but not least, we sought out and found methodological diversity.     

The structure of traits delineating personality disorder in a Chinese sample

The present study examined the factorial structure of a Chinese language version of the self-report Dimensional Assessment of Personality Pathology Questionnaire in 581 adults. Four factors were extracted (Emotional Dysregulation, Dissocial, Inhibition, and Compulsivity) that are similar to the factors extracted in the scales' normative clinical and general population samples from North America (factor comparability coefficients range from .88 to .96), supporting the idea that this trait structure is invariant across diverse populations. The internal consistency of the scales (Cronbach's alpha) was satisfactory across age and gender groups with the exception of the Intimacy Problems scale. Possible explanations for the poor internal consistency of the Intimacy Problems scale, such as cultural differences in social factors influencing marital and romantic relationships in Chinese populations, as opposed to other populations are discussed.     

中学生不同焦虑水平与认知策略研究

使用测试方式对中学生的焦虑水平和认知策略之间的关系进行了研究。结果发现,在7钟认知策略中能力认识、失败归因、命运控制和社会关系4种认知策略在三个级别的焦虑组之间存在显著差异,焦虑水平高的人倾向于使用否定自身能力、选取失败、悲惨宿命论和消极社会关系认知策略。除成就认识外．其他认知策略不存在性别差异,女性倾向于产生低成就认知。     

Effects of a high salt diet on blood pressure responses to acoustic stimuli in borderline hypertensive rats (BHR)

The borderline hypertensive rat (BHR) responds to environmental and dietary stressors with elevated blood pressure. The first two months of a high salt diet appear to be the time of greatest sensitivity to salt effects on the blood pressure of BHR. The current study was conducted to examine whether exposure to salt diets varying in duration for up to two months differentially affects baseline blood pressures (systolic, SBP, and diastolic, DBP) and blood pressure responses to novel acoustic stimuli in BHR and normotensive Wistar-Kyoto (WKY) rats. Male BHR and WKY were fed a control (1%) salt diet or a high (8%) salt diet for 1, 1.5, 2.5, or 8.5 weeks. SBP and DBP responses to an acoustic stimulus (85 dB, 3 kHz) were measured upon completion of the diets at 12 weeks of age. Ten acoustic trials (one stimulus/minute) were presented and blood pressure responses were recorded in 2-second blocks spanning the 10 seconds prior to and following stimulus presentation. BHR had higher resting SBP and DBP than WKY, and 8.5 weeks of 8 percent salt increased SBP markedly in BHR. SBP and DBP labilities in the initial trial were greater in BHR than WKY with high salt diet durations of 2.5 and 8.5 weeks producing greater lability in later trials. Few differences were noted in pressor responses, but BHR had more dramatic depressor responses than WKY in early trials, and BHR pressures had a more dramatic return to baseline. It appears that genetic history and salt diet can affect blood pressure lability and recovery in response to novel stimuli in genetically susceptible animals.     

心理学全球化的趋势

全球化心理学或心理学全球化是当代心理学的一个新取向。它产生的基本动力是当今世界全球化浪潮的出现,主流心理学的局限以及本土心理学的兴起,其基本目标是研究全体人类的心理和行为,力图建构起最具统合性的心理学。
