交互进化计算对焦虑测量的适用性探析

大量的研究用stroop色词命名任务和点探测任务等经典的情绪研究方法证明了社交焦虑个体情绪识别的特殊性。该研究采用IEC(交互进化计算)的方法, 研究了焦虑组和对照组(低焦虑组)在情绪感知动态范围上的差异性。实验要求第一组被试利用给出的IEC情绪识别光影系统设计出符合实验维度(高兴、恐惧)的图片, 并让第二组被试对图片进行评估, 得出每幅图片的心理数值范围。实验结果说明IEC可以适用于常规优化系统之外的一个新领域—— 心理健康的测量,同时也表明社交焦虑个体的情绪感知动态范围窄于正常人。     

网络广告的心理传播效果及其理论探讨

网络广告现已得到众多商家的重视与青睐。研究发现, 网络广告的心理传播效果明显受到广告自身特点(如网络广告的形式、互动性、情感元素、产品类型)、受众状态(如受众的期待、卷入度、先前经验、性别)、以及网络环境等因素的影响。学者们利用修正的精细加工可能性模型、互动广告模型、网络广告心理效果模型等对该类广告效应进行理论解释。但现有研究也依然存在一些问题, 如影响因素有待拓展、研究方法有待创新、因变量指标有待规范、理论总结不力等。     

青少年外向／宜人性人格、互联网服务偏好与“网络成瘾”的关系

该研究采用问卷法,以481名中学生为被试,通过无约束结构方程模型分析方法探讨了外向性、宜人性人格特征与互联网服务偏好的交互作用对网络成瘾的影响。研究发现在对网络成瘾的影响上,青少年宜人性人格特征与互联网社交服务偏好存在显著的交互作用,但与互联网娱乐、信息和交易服务偏好的交互作用不显著。外向性人格特征与互联服务偏好不存在显著的交互作用。(1)从平均影响来看,外向性、宜人性、互联网社交、娱乐和交易使用偏好能够正向预测网络成瘾,互联网信息使用偏好对网络成瘾没有显著的预测效果;(2)在宜人性高分组中,互联网社交服务偏好与PIU的正向关系要强于宜人性低分组。斜率检验表明对于低宜人性人格的青少年来说,互联网社交服务偏好不易导致其成瘾,而对高宜人性人格的青少年而言,互联网社交服务偏好反而容易导致其成瘾。     

Collective Action as Individual Choice

We argue that conceptual analyses of collective action should be informed by game-theoretic analyses of collective action. In particular, we argue that Ariel Rubenstein’s so-called ‘Electronic Mail Game’ provides a useful model of collective action, and of the formation of collective intentions.     

The interactive effects of temperament and maternal parenting on toddlers' externalizing behaviours

The present study aimed to determine the potential moderating effects of temperamental traits on the relation between parenting and toddlers' externalizing behaviours. For that purpose, this study examined the interplay between temperament and maternal parenting behaviours in predicting the level as well as the development of toddlers' externalizing behaviours. Participants were 115 boys (wave 1, M=16.9 months; wave 2, M=23.2 months) and their mothers, who were observed in a 13‐min structured play session at home. With regard to the prediction of the level of externalizing behaviours at wave 1, main effects were found for children's temperamental characteristics. In addition, maternal negative control interacted significantly with children's inhibitory control in predicting this level of externalizing behaviours. The findings with regard to the development of externalizing behaviours showed that the effects of maternal negative control and lack of maternal sensitivity were stronger for toddlers with a difficult temperament: maternal negative control and lack of maternal sensitivity were related to an increase in externalizing behaviours for temperamentally difficult children only. These results offer support for the goodness‐of‐fit hypothesis, stressing the idea that the effects of temperament and the social environment depend to a large extent on their interplay.

An interactive multiobjective procedure for selecting medium-term countermeasures after nuclear accidents

This paper presents a methodology for supporting medium-term decisions in the context of nuclear accidents. An interactive procedure based on a multiobjective linear model is introduced, allowing the set of feasible strategies to be explored. This procedure enables the users to express preferences on both criterion values and the structure of the strategies. Additional flexibility is provided by the possibility of integrating evolutive constraints during the decision process. © 1998 John Wiley & Sons, Ltd.     

浅谈医学教育中的多媒体课件制作与启发、诱导式教学

合理地制作和运用多媒体课件,并充分发挥它的优势,与现代医学教育的启发、诱导式教学相结合。教员本身对所讲内容要充分理解,掌握多媒体课件制作的技巧,把自己的想法恰当地融入到幻灯片中。在实际运用过程中有一些具体的方法,如逐步出现、适当修饰、利用超级链接、合理插入图片、把正常片和异常片同时出现在一张幻灯片上等。     

涉空对话中表征对齐的产生机制

人类如何处理并交换空间信息是现有空间认知领域的热点问题, 这一过程主要是通过涉空对话实现的。在涉空对话中存在着表征对齐现象, 互动双方在对话中会实现空间术语、空间参照系及空间视角等表征的对齐。空间场景物理特征和人与人的协作都会影响表征对齐的程度, 而实现表征对齐的生理基础是对话双方神经活动的一致性。未来可继续探究表征对齐的作用机制, 如与个体空间偏好的关系, 以及合作伙伴特征如何影响表征对齐的程度等。     

多媒体学习中线索原则是否存在经验逆转效应?——来自两项元分析的证据

经验逆转效应指出,对低先备知识者学习有积极作用的教学设计可能对高先备知识者无效,甚至有消极影响。本研究分别对高、低先备知识者进行关于线索对其学习过程中主观认知负荷及学习结果影响的元分析,检验线索原则是否存在经验逆转效应及认知负荷理论能否解释线索原则的经验逆转效应。结果表明,线索能降低低先备知识者学习过程中的主观认知负荷并促进其学习表现;但线索对高先备知识者认知负荷及学习成绩的总效应均不显著。结合元分析结果,本研究证明了在多媒体学习环境下线索原则存在部分经验逆转,且部分支持了线索原则经验逆转效应的认知负荷理论解释。     

Choice Behaviour in a Computer-Aided Multiattribute Decision Task

Choice behaviour in an interactive multiple-criteria decision-making environment was examined experimentally. The main purpose was to investigate whether subjects are more comfortable in processing criterion/attribute information simultaneously (in parallel) or sequentially. As a research instrument, three different interactive software systems were used on a microcomputer by management students at the Helsinki School of Economics and Business Administration and the Institute of National Economy in Moscow to solve essentially the same problem of buying/leasing a home tailored to the respective decision environments. The experiments also provided us with a possibility to learn useful lessons about how human subjects make computer-supported choices. The results of the experiments are discussed. Furthermore, questions for future research are suggested. © 1997 John Wiley & Sons, Ltd.
