语文学习困难儿童汉字记忆编码的神经机制研究

采用事件相关电位方法,探讨语文学习困难儿童汉字记忆编码过程的特点.研究发现:语文学习困难组和对照组在编码过程的300-700ms均存在显著的相继记忆效应.语文学习困难组与对照组的Dm效应存在着显著的时间与空间上的差异.在Dm效应出现前,语文学习困难组加工的P2潜伏期显著晚于对照组.同时还发现,不同能力组加工的N2和LPC差异与Dm效应十分相似,对照组比语文学习困难组更正,与Dm效应不同,不同能力组加工的分离明显大于Dm效应的分离,且持续时间更长,一直持续到1000ms之后,远远晚于Dm效应的分离时间,对照组比语文学习困难组有一个更正的晚正成分.语文学习困难组与对照组在加工程度上存在差异,使编码项目的记忆痕迹呈现出不同特点.     

大动脉炎与继发性高血压

大动脉炎(Takayasu arteritis,TA)是一种累及主动脉及其主要分支的慢性进行性非特异血管炎性疾病,多发于年轻女性.高血压是大动脉炎的常见临床表现之一,对于大动脉炎引起的继发性高血压,应给予积极的综合治疗,降压治疗的同时,活动期患者应用糖皮质激素和/或免疫抑制剂控制病情,酌情给予抗栓、抗动脉硬化等综合性治疗措施,对于稳定期患者必要时行介入或外科手术治疗以解除导致血压升高的血管病变或主动脉瓣病变.临床医师应提高对该疾病的认识以免造成误诊或漏诊.

患者报告结局（PRO）在临床疗效评价体系中的应用与思考

现代医疗模式的转变,使得患者对疾病的直接感受,对疗效的评价,成为临床决策和药物安全性评价的重要指标。而PRO量表的问世,使患者有机会真正参与到医疗过程中来,也为临床疗效评价及药物管理提供了珍贵资料。本文将通过什么是PRO、PRO的价值以及PRO的发展近况来对PRO做一个初步的介绍,以便为后来的研究者提供可能的帮助。     

Acceptability of Behavioral Family Therapy among Caregivers in China

In the U.S., helping the noncompliant child and parent child interaction therapy represent behavioral family therapy programs that are empirically supported for treating the conduct problems of 2- to 7-year old children. This study examined how caregivers in China would view behavioral family therapy. Caregivers in Hangzhou, China reported the perceived age of deviance for behavioral family therapy targets (e.g., noncompliance) and rated the acceptability of behavioral treatment components (e.g., timeout). Chinese caregivers agreed with European-American culture on considering noncompliance, aggression, tantrums, and negative talk deviant during the pre-school period. Overall, Chinese caregivers considered all the following nine behavioral family therapy components acceptable: contingent praise, responsive play, ignoring deviant attention seeking, authoritative instruction-giving, warnings, chair timeouts, ignoring tantrums during timeout, room backups for chair timeouts, and immediate timeouts for aggression. However, specific parental reservations were found regarding backup procedures for chair timeouts, particularly room backups. Possible treatment accommodations of behavioral family therapy for Chinese families are discussed.     

Fate or fight: Exploring the hedonic costs of competition

As a resource-allocation method, free competition is generally considered more efficient and fairer than binding assignment, yet individuals’ hedonic experiences in these different resource-allocation conditions are largely ignored. Using a minimalistic experimental simulation procedure, we compared participants’ hedonic experiences between a free-competition condition (in which participants could equally and freely compete for the superior resource) and a binding-assignment condition (in which the superior and inferior resources were unequally and irreversibly assigned to different participants). We found that individuals in the binding-assignment condition – even the disadvantaged ones – were happier than those in the free-competition condition. We attributed the effect to individuals’ peace of mind, and supported the peace-of-mind notion by identifying two moderators: ease of social comparison and enjoyability of the inferior resource. In sum, this research highlighted the hedonic aspects of resource allocation methods and identified when accepting one’s fate is hedonically better than fighting for the best.     

Does the distance between us matter? Influences of physical proximity to others on consumer choice

Individuals’ physical closeness to one another can either increase or decrease their preference for distinctive products. When individuals perceive their proximity to others to be voluntary, they are likely to interpret it as an indication of their affiliation motivation. Consequently, in a product choice task, they choose options that others consider desirable. When people perceive that their close proximity to others results from circumstances beyond their control, however, they feel that their personal space is violated and experience a need for to express their individuality. In this case, they are more likely to choose products that distinguish themselves from others.     

蒙语词汇识别中语音自动激活的ERP研究

采用快速掩蔽启动范式、Go/No-go范式和事件相关电位（ERP）技术,探讨蒙语词汇识别过程中语音自动激活的时程及对语义通达的作用。实验中要求被试执行一个额外的语义分类任务,对关键刺激不做明显的行为反应。结果发现,SOA为67ms时,语音启动在头皮的额区诱发了明显的P150和N400成分;SOA为167ms时,语音启动在头皮的额区和中央区诱发了明显的P200成分,在整个大脑皮层诱发了明显的N400成分。结果表明,语音在蒙语词汇识别的早期自动激活并促进语义的通达。     

青少年创造性人格和创造性的关系：来自中美比较的证据

通过对中美400名13-15岁青少年问卷调查,比较了中美青少年创造性人格及其与创造性之间的关系.结果发现：（1）和单个创造性人格变量相比,创造性人格的内部因素、外部因素和自我因素和创造性之间的相关均达到中等程度,且均非常显著,中国青少年创造性人格三个因素能解释创造性变异的11％,美国青少年创造性人格三个因素能解释创造性变异的15％.（2）在创造性上,美国青少年在所有维度上的得分均显著高于中国青少年,但在创造性人格上,只有在自我因素上,中国青少年创造性人格得分高于美国青少年,其他因素不存在差异,这说明创造性人格不是造成中美青少年创造性差异的主要原因.
