云南省大学生自杀行为及相关因素分析

采用SCL-90、青少年生活事件量表、应对方式量表、社会支持评定量表和自编的外显行为量表对云南省3313名大学生进行了测查,并探讨了包括自杀意念及自杀企图在内的自杀行为状况及其影响因素。结果表明:(1)427(13.2%)名大学生有自杀意念,卡方检验显示女生人数显著多于男生;154(4.7%)名大学生有过自杀企图,男女生人数没有显著差异;(2)自杀意念和自杀企图在人口统计学变量上有显著差异:在自杀意念上,女生、独生子女、文科生、来自城市的学生和不完整家庭的学生、月支出少于100元的学生得分显著高于与之对应的大学生;而在自杀企图上,只有来自城市的学生和不完整家庭的学生、月支出少于100元的学生得分显著高于与之对应的大学生;(3)大学生自杀意念和自杀企图与心理症状、生活事件、情感中心应对呈显著的正相关,与问题中心应对、社会支持呈显著的负相关;(4)在结构模型中,社会支持在心理症状和自杀行为中起到显著的调节作用,情感中心应对在生活事件、社会支持、社会支持对心理症状的调节作用中起显著的中介作用,而问题中心应对在生活事件、社会支持、社会支持对事件的调节作用中起显著的中介作用。     

卡车驾驶员的夜间视力研究

运用ＹＪＳ—ＩＩ型夜间视觉检查仪对２３８名男性卡车驾驶员的暗适应时间和夜间视力进行了测试。结果表明：卡车驾驶员暗适应时间的９５％上限值为５９．６７秒;卡车驾驶员暗适应时间和夜间视力的年龄阈值为４０岁;事故组与安全组卡车驾驶员暗适应时间存在显著差异（Ｐ＜０．０５）,事故组卡车驾驶员的暗适应时间较长,表明卡车驾驶员的暗适应能力差是引起夜间交通事故的重要因素。研究结果为驾驶员的选拔,安全教育以及制订预防夜间交通事放对策提供一定的理论依据。     

COPE量表的初步修订

以我国７４４名文、理、工科大学生为被试,对ＣｈａｒｌｅｓＳ．Ｃａｒｖｅｒ等编制的ＣＯＰＥ量表进行了初步修订。结果表明：ＣＯＰＥ量表在我国大学生中应用具有良好的信度和效度,基本符合心理测量学标准,可以作为评估应付活动的工具。     

Synelfin Regulation during the Critical Period for Song Learning in Normal and Isolated Juvenile Zebra Finches

Male zebra finches (Taeniopygia guttata) learn to sing during a critical period in adolescence. We previously described a presynaptic protein, synelfin, whose mRNA is increased early in this critical period in a brain nucleus specifically implicated in song learning, lateral MAN (lMAN). In the current study, in situ hybridization was used to map this change in gene expression to the subregion of lMAN that projects to the robust nucleus of the archistriatum (RA), the principal motor output of the telencephalic circuit that controls song production. Using confocal immunofluorescence microscopy, we detected numerous puncta of synelfin immunoreactivity that apparently represent presynaptic terminals from lMAN in the RA of young males. Synelfin immunoreactivity in RA declined abruptly between 40 and 45 days of age, a time of major synaptic reorganization in RA. This change did not occur until about 10 days after the decline in synelfin mRNA in cell bodies within lMAN, indicating a relatively slow turnover of the protein in presynaptic terminals and suggesting that some of the functional changes that occur during the critical period may arise from regulatory decisions that were initiated a week or more earlier. Depriving birds of tutoring did not halt or delay the decline of synelfin mRNA in lMAN. This change in gene expression must not be a consequence of early song learning, but may reflect an innate or programmed step in song circuit development.     

家兔具有分辨红绿的色觉行为

本文在11只上海家免上进行了色觉行为学的实验研究。通过限制方位、光强等可能成为条件刺激的因素,并排除了声音、气味、背景光刺激等的干扰,确保颜色成为唯一的条件刺激,建立食物性红绿色觉分辨条件反射。经过适应、筛选、驯练和测试,在家兔上建立了对绿光稳固的条件反射。该结果显示兔具有颜色分辨能力。     

Effects of Gender and Profession Type on Definitions of Violence Against Women in Hong Kong

This study investigated the criteria chosen by male and female Chinese public servants (clinical psychologists, social workers, police officers, physicians, nurses, teachers, and lawyers) in Hong Kong to classify and define violence against women. Data were gathered via questionnaires completed by 2589 (686 male) public servants from 10,476 polled (response rate 24.7%). The questionnaires included a 14-item check-list of various behaviors constituting violence against women and a 10-item check-list of criteria that could be used to categorize behavior as violence against women. It was found that for this population, use of physical force and lack of consent were the main determinants of violence against women. Only half of respondents considered murder a form of violence against women, the rest categorized it as a crime that was "not merely violence." Most respondents defined sexual harassment, rape, and unwanted physical contact as forms of violence against women. The female public servants were more likely to define behaviors as violence against women and to use more criteria to define violence against women. Public servants who worked with the law enforcement and legal system were more likely than others to choose narrow definitions and rigid criteria.     

隔离动物学习能力的研究

有关人和动物的学习能力与早期环境之间的关系的研究已有了很长的历史。一般认为早期受限制的环境损害了智力,而早期丰富的环境提高了智力。在这个领域里大部分的研究集中在比较丰富环境的动物和隔离动物的学习能力的差异,然而许多工作在近年来受到了质疑。丰富环境中情景复杂,活动场所大,有隧道、平台、游泳门,活动轮等。丰富环境经验的迁移以及丰富生活环境与学习迷津测试场景的类似性可能在动物完成学习课题时起了重要作用。     

儿童对汉语主动名、被动句转换理解的比较研究

本研究的目的是探讨正常、低常、耳聋儿童对汉语主动句、被动句转换理解的能力问题。实验材料是十组主动句、被动句转换类型,呈现了汉语主动句、被动句转换的全部形式,字词水平控制在聋哑小学二年级程度。要求被试正确进行思惟。被试是9至13岁的正常、低常、耳聋小学生,每个年龄组的被试在30人以上,14、18岁的21名耳聋学生也参加了实验,共计被试为208人。 实验结果表明:总体上看,三类被试对于汉语主动句、被动句的转换理解,正常儿童高于耳聋儿童,耳聋儿童高于低常儿童,差异是显著的。从各年龄阶段看,耳聋儿童转换能力低于正常儿童并不是绝对的。从转换能力发展的转折期看,正常儿童的明显转折期出现在10至11岁,低常儿童出现在12至13岁,耳聋儿童在12至13岁的发展接近转折期。从转换理解与语文、数学教育的相关关系来看,没有发现语文和数学教育对转换理解的有规律的必然影响。从理解的特点上看,三类被试在理解上呈现出一致的倾向。
