音乐之脑

回顾并总结了近年来对音乐认知神经基础的研究结果,包括人类感知乐曲的音高、理解音乐的结构和意义中的脑基础,音乐家和普通人在音乐认知上的脑功能差异,以及东西方听众在聆听本土和非本土音乐时的脑活动差异,并对国内利用脑功能成像技术和事件相关电位技术研究音乐认知的前景作出展望     

关于中国心理健康服务体系建设的若干问题

从我国心理健康服务的基本模式、技术体系、服务主体、教育培训、管理监督等五个方面回顾了我国心理健康服务体系的现状。近二、三十年来,我国心理健康服务体系从无到有,发展迅速,但也存在若干亟待解决的问题:服务的技术体系不完善,心理服务的从业机构和个人良莠不齐、总体水平偏低,从业人员的教育培训、从业人员和机构的资质认证缺乏有效的监督管理机制等。目前我国的心理健康服务体系难以适应社会对心理健康服务的需求。需要立足国情,借鉴外国的成功经验并结合我国传统文化,以扎实的研究和细致的工作来完善我国的心理健康服务体系。     

无关声音效应研究述评

中学生元担忧与一般焦虑

根据AdrianWells的一般焦虑的担忧模式 ,对广州市 6 36名中学生元担忧状况以及元担忧与一般焦虑的关系进行了研究。结果发现 ,高中生元担忧水平高于初中 ,显著差异。初中二年级和高中二年级的元担忧水平高于其他两个年级 ,尤其是初中 ,显著差异。中学生元担忧的性别差异不明显。中学生元担忧各因素与焦虑均存在极显著正相关 ,考试、家庭、心理健康、外貌和身体健康 5个元担忧因素对焦虑的贡献显著     

MAU程序和自由讨论的群体决策质量比较

采用实验室研究方法,比较了在信启、不分享条件下多特征效用模型(MAU)决策程序和自由讨论对群体决策质量的影响,并对影响MAU决策质量的主要因素进行了初步探讨。结果发现：(1)MAU程序可以较好地克服群体动力学方面的一些消极影响,表现出挖掘信息(尤其是非分享信息)的充分性。但MAU程序在被试的态度和社会交互作用等心理效标上并未显示出优势;(2)在MAU条件下,群体规模的增大对分享和非分享信息的讨论量无显著影响。而任务难度效应要和群体规模一起才能起到作用。     

Aggression in toddlers: associations with parenting and marital relations.

This study examined the relation among parenting factors, marital relations, and toddler aggression. A structured questionnaire was administered to both parents of 254 2-year-olds. The authors used correlation and hierarchical multiple regression analyses to assess the extent to which certain personality traits, drug use, parenting style, and marital conflicts were related to the toddlers' aggressive behavior. Results showed that the maternal child-rearing and parental aggression domains had a direct effect on toddler aggression. The domain of maternal child rearing also served as a mediator for the domains of marital relations, paternal child rearing, parental aggression, and parental drug use. The findings indicated that maternal child-rearing practices, personality attributes, and drug use were more important than paternal attributes in relation to toddler aggression. Implications for prevention among families at risk are discussed.     

Group identity and peer relations: A longitudinal study of group identity,perceived peer acceptance,and friendships amongst ethnic minority English children

This research examined whether peer relationships amongst ethnic minority status children reflect the social groups to which children belong and the degree to which they identify with these groups. A longitudinal study was conducted to investigate the influence of group identities (i.e., ethnic and national) on children's perceived peer acceptance and preference for same‐ethnic friendships. Measures of ethnic and English identification, perceived peer acceptance, and friendship choice were administered to 207 south‐Asian English children, aged between 5 and 11, at two time points 6 months apart. In line with predictions, longitudinal analysis showed that bicultural identification (i.e., higher ethnic and English identity) was related to higher perceived peer acceptance and less preference for same‐ethnic friendships. Importantly, as hypothesized, this finding was limited to the older children with more advanced social‐cognitive abilities. The results suggest that older children who adopted a bicultural identity were able to strategically ‘flag’ their multiple group identities, within their multicultural peer groups, to obtain acceptance amongst the maximum number of peers and show less preference for same‐ethnic friendships. This study extends previous peer relations research, which has typically focused on individual social deficits or classroom norms, by showing that group identities influence peer relationships amongst ethnic minority status children.     

Dynamic Motivational Processing of Antimarijuana Messages: Coactivation Begets Attention

In the theoretical framework of dynamic motivational activation, this study reveals the dynamics of antimarijuana public service announcement (PSA) processing, especially the processing of co‐occurring positive and negative content. It specifies the important role of endogenous feedback dynamics of the information processing system and teases them apart from exogenous message effects. As suggested by real‐time psychophysiological responses (heart rate, skin conductance level, and facial electromyography), the copresence of positive and negative content is most attention eliciting and is not moderated by individuals' marijuana experience. Marijuana experience, however, increases attention to arousing content in the PSAs, increases smiling responses to positive content, and escalates arousal to the PSAs in general. Implications for designing and evaluating PSAs and health campaigns are discussed.     

新疆维吾尔、哈萨克、回族519名男青年试用EPQ问卷的初步报告

本文报告以维吾尔(简称维)、哈萨克(简称哈)、汉语EPQ问卷对新疆维、哈、回族519名16～29岁男青年的测查结果。表明EPQ各量表间相关情况和总趋势与英国、龚氏常模相似,P量表分均为最低;L量表分与龚氏常模一样均为最高。维、哈族个性特征显著外倾,尤以哈族突出。提出民族的历史发展、社会文化传统、劳动生活方式等因素是形成维、哈族个性特征的基础,认为龚氏常模及其划界分需进一步修订和完善。     

Scheduled running wheel activity indexes the specificity of pharmacological anorexia.

Nondeprived male Sprague-Dawley rats that were given scheduled access to running wheels for 60 min daily ran immediately and energetically. Intraperitoneal injections of 400 micrograms/kg pancreatic glucagon and 0.15 microgram/kg cholecystokinin octapeptide had no effect on scheduled running, but significantly inhibited feeding when the rats were offered condensed milk instead of access to the running wheels. This is consistent with the hypothesized function of these peptides as postprandial satiety signals. In contrast, 0.5 mg/kg amphetamine and 75 microM/kg LiCl, which produced similar degrees of anorexia, inhibited running by about 50%. Amphetamine, but neither peptide, also inhibited water drinking and disrupted the behavioral sequence of postprandial satiety. The distance run during scheduled running tests was inversely related to body weight, but the patterns of the drugs' effects were not altered by baseline running differences. Scheduled wheel running is a robust consummatory behavior that appears to provide a relatively valid, simple, and sensitive test of the behavioral specificity of pharmacological anorexia.
