Bug distribution and statistical pattern classification

A model (called the rule space model) which permits measuring cognitive skill acquisition, diagnosing cognitive errors, detecting the weaknesses and strengths of knowledge possessed by individuals was introduced earlier. This study further discusses the theoretical foundation of the model by introducing bug distribution and hypothesis testing (Bayes' decision rules for minimum errors) for classifying subjects into their most plausible latent state of knowledge. The model is illustrated with the domain of fraction arithmetic and compared with the results obtained from a conventional artificial intelligence approach.The authors would like to acknowledge Mr. Robert Baillie for developing several computer programs used for this research.This research was sponsored by the Personnel and Training Research Program, Psychological Sciences Division, Office of Naval Research.Some of the analyses presented in this report were performed on the PLATO® system.

Jungian theory of dreaming and contemporary dream research – findings from the research project ‘Structural Dream Analysis’

The research method ‘Structural Dream Analysis’ (SDA) is described which allows for systematic and objective analysis of the meaning of dreams produced by patients in Jungian psychotherapies. The method focuses especially on the relationship between the dream ego and other figures in the dream and the extent of activity of the dream ego. Five major dream patterns were identified which accounted for the majority of the dreams. The clients’ dream series were dominated by one or two repetitive patterns which were closely connected to the psychological problems of the dreamers. Additionally, typical changes in the dream series’ patterns could be identified which corresponded with therapeutic change. These findings support Jung's theory of dreams as providing a holistic image of the dreamer’s psyche, including unconscious aspects. The implications for different psychoanalytic theories of dreaming and dream interpretation are discussed as well as implications for the continuity hypothesis.     

幼儿在辨别过程中图形维度显著性的研究

采用Triad Classification法和等级图形模式研究了4～6岁幼儿在辨别过程中图形维度显著性效应。实验1让幼儿进行自由辨别任务,发现颜色显著性强于形状,局部特征的显著性强于整体特征;随被试年龄增长,整体特征和颜色的显著性逐渐增强;对维度显著性等级模式的信息加工比对整体局部特征等级模式的加工反应时长。实验2进行按指定标准来辨别的任务,发现仍然出现图形维度显著性效应。这些结果说明图形维度显著性效应可能是自动发生的,可能比整体局部特征的认知加工更复杂。     

空间书写障碍的个案研究

根据书写加工理论,从异形字水平、图解动作模式水平和神经动作执行水平三个方面,综合考察一例空间书写障碍儿童的认知加工特点。结果表明：（1）个案QY的异形字水平出现选择性损伤,在视觉整体特征的知觉加工上存在困难,导致自发书写的汉字难以辨识,存在严重的间架结构问题。（2）个案QY在图解动作模式水平以及神经动作执行水平上表现正常     

电子商务中消费者购买决策及其影响因素

电子商务是随着计算机和互联网技术的发展而出现的一种新经济模式, 它正在广泛而深刻地影响着人们的购物观念和购物方式。网上购物是指通过互联网购买商品或享受服务, 也是通常所指的电子商务。国内外关于网上购物的研究缺乏从影响因素到中介作用最后到实际购买关系的整体研究框架。研究者从消费者角度提出了网上购物决策的整体框架, 拟采取访谈法、问卷调查、实验室模拟方法和服务器日志文件收集数据, 探讨我国文化背景下消费者的网上购买决策, 拟探明：影响消费者网上购买决策的因素; 风险认知和网上购物态度在模型中的中介作用; 产品类型、消费者类型及其与网上购物决策模式的关系。预期研究成果对我国电子商务购物环境的改善、电子商务网站的设计、网上营销策略的制定有着重要的意义。     

Time manages interference in visual short-term memory

Emerging evidence suggests that age-related declines in memory may reflect a failure in pattern separation, a process that is believed to reduce the encoding overlap between similar stimulus representations during memory encoding. Indeed, behavioural pattern separation may be indexed by a visual continuous recognition task in which items are presented in sequence and observers report for each whether it is novel, previously viewed (old), or whether it shares features with a previously viewed item (similar). In comparison to young adults, older adults show a decreased pattern separation when the number of items between “old” and “similar” items is increased. Yet the mechanisms of forgetting underpinning this type of recognition task are yet to be explored in a cognitively homogenous group, with careful control over the parameters of the task, including elapsing time (a critical variable in models of forgetting). By extending the inter-item intervals, number of intervening items and overall decay interval, we observed in a young adult sample (N?=?35, M_age?=?19.56 years) that the critical factor governing performance was inter-item interval. We argue that tasks using behavioural continuous recognition to index pattern separation in immediate memory will benefit from generous inter-item spacing, offering protection from inter-item interference.     

Emotional intelligence (EI), conflict resolution patterns,and relationship satisfaction: Actor and partner effects revisited

This study tested for actor and partner effects in the relationship between ability-based EI and adaptive marital relationships and satisfaction employing a standard dyadic design involving 100 young heterosexual couples. Participants were assessed on the MSCEIT along with measures of conflict resolution patterns and perceived marital satisfaction. A series of path analyses provided support for actor effects—but not partner effects—in the association of EI, assessed as ability, and marital variables. Overall, the data provide only partial support for the common claim and some prior research suggesting that EI plays a pivotal role in marital relationships.     

生态心理学——心理学研究模式的转向

生态心理学是西方心理学的一种新取向,它在方法论上倡导将交互作用原则作为主要研究原则,具体来说,就是主张实际生活环境的研究原则、多元方法选择原则、多元交互解释原则,这些原则带来了心理学研究模式的转向：从探讨思辨中或实验室中的心理向探讨真实环境中的心理转变;从人的心理内部机制的探求转向对人和环境互动关系的探求;从对理论模型的追问到对理论背景与实验设计之间匹配的关注;从分析性思维模式为主转向综合性思维模式。
