注意缺陷多动障碍的研究与治疗

注意缺陷多动障碍（ADHD）的发病群体多为5岁以后的儿童,主要临床表现是多动、冲动,注意力无法集中,对一项任务不能够有规划进行下去,而且脾气暴躁、易怒。近年来,心理学界、神经科学界和教育学界等对ADHD的研究取得了很多进展。本文概括性地介绍了ADHD病症的基本特征,目前对于患者脑机制损害的研究,并从药理学和行为学等方面讨论了ADHD的治疗方法和手段。     

图形项目记忆与位置来源提取的ERP研究

采用事件相关电位（ERP）方法研究大学生图形项目记忆与位置来源提取新/旧效应的时、空分布特征。学习屏幕左侧（或右侧）呈现的图形后在屏幕中央呈现某一测验项目（已学图形或新图形）,对受试者进行两类测验：其一是判断该项目是否已学过;其二是将从某侧学过的测验项目判断为目标,而将其它测验项目判断为非目标的来源测验（排除任务）。实验结果表明：图形位置来源提取比项目再认新/旧效应的头皮分布更广,持续时程更长;与前人相同实验范式的研究结果相比,本研究位置来源提取效应的头皮分布范围较广;非目标-旧图形与目标图形新/旧效应的头皮激活程度不同。上述结果说明：图形位置来源提取比项目再认激活的大脑区域更多,这与双重加工模型的观点一致;实验范式和来源知觉的特性共同调节来源记忆新/旧效应的时、空分布特征;意识水平对来源信息提取的新/旧效应存在一定的影响     

智能革命时代下脑机接口之于人类延展的伦理审思

脑机接口通过解码人类思维活动过程中的脑神经活动信息,构建出人脑与外部环境之间的直接信息交流和控制通路,帮助我们突破身体局限,增强人体机能。脑机接口技术将人的延展方式和水平提升至了一个新的境界,为人类认识自己开辟了新的维度。作为一种革命性的人机交互方式,脑机接口延展了人类身份的范畴,使人机混合体的赛博格身份成为可能;它延展了人类身体的边界,使超越身体局限的梦想成为可能;它延展了人类实践的方式,使意念控制的愿景成为可能。脑机接口技术在造福人类展现高价值的同时,也难免存在着高风险,其价值负载和伦理挑战越来越为人们所关注和重视。

     

Reconsidering the path for neural and physiological methods in consumer psychology

Recent decades have witnessed a burst of neuroscience research investigating mental and physiological processes central to consumer behavior, including sensory perception, memory, and decision making. Nonetheless, few publications that include neural and physiological measures, or develop conceptual frameworks around neuroscience principles, have been published in consumer psychology. It is clear that “consumer neuroscience” has thus far not lived up to its promises in the marketing literature. We suggest three main reasons for this. First, neural and other biological markers are often mistaken to be identical to the overlaying psychological constructs in traditional consumer psychology work. Second, somewhat surprisingly, there has been an overly narrow utilization of neural data. Most previous work focused on linking existing behavioral phenomena or psychological constructs central to consumer research to neural correlates using brain imaging techniques while ignoring other methods. We argue that much can be gained from improved integration of physiological measures and through them, different levels of analysis. Third, there remain significant structural hurdles to the broad adoption of neural and physiological measures for consumer researchers. We outline how addressing these three components can translate to a more holistic understanding of the consumer via both broader and deeper consumer insights.

Complex Communication Dynamics: Exploring the Structure of an Academic Talk

Communication is a multimodal phenomenon. The cognitive mechanisms supporting it are still understudied. We explored a natural dataset of academic lectures to determine how communication modalities are used and coordinated during the presentation of complex information. Using automated and semi‐automated techniques, we extracted and analyzed, from the videos of 30 speakers, measures capturing the dynamics of their body movement, their slide change rate, and various aspects of their speech (speech rate, articulation rate, fundamental frequency, and intensity). There were consistent but statistically subtle patterns in the use of speech rate, articulation rate, intensity, and body motion across the presentation. Principal component analysis also revealed patterns of system‐like covariation among modalities. These findings, although tentative, do suggest that the cognitive system is integrating body, slides, and speech in a coordinated manner during natural language use. Further research is needed to clarify the specific coordination patterns that occur between the different modalities.     

The heterogeneity of attention‐deficit/hyperactivity disorder symptoms and conduct problems: Cognitive inhibition,emotion regulation,emotionality, and disorganized attachment

This study examined the contributions of several important domains of functioning to attention‐deficit/hyperactivity disorder (ADHD) symptoms and conduct problems. Specifically, we investigated whether cognitive inhibition, emotion regulation, emotionality, and disorganized attachment made independent and specific contributions to these externalizing behaviour problems from a multiple pathways perspective. The study included laboratory measures of cognitive inhibition and disorganized attachment in 184 typically developing children (M age = 6 years, 10 months, SD = 1.7). Parental ratings provided measures of emotion regulation, emotionality, and externalizing behaviour problems. Results revealed that cognitive inhibition, regulation of positive emotion, and positive emotionality were independently and specifically related to ADHD symptoms. Disorganized attachment and negative emotionality formed independent and specific relations to conduct problems. Our findings support the multiple pathways perspective on ADHD, with poor regulation of positive emotion and high positive emotionality making distinct contributions to ADHD symptoms. More specifically, our results support the proposal of a temperamentally based pathway to ADHD symptoms. The findings also indicate that disorganized attachment and negative emotionality constitute pathways specific to conduct problems rather than to ADHD symptoms.     

Formal assessment of reliability specifications in embedded cyber-physical systems

Reliability has become an integral component of the design intent of embedded cyber-physical systems. Safety-critical embedded systems are designed with specific reliability targets, and design practices include the appropriate allocation of both spatial and temporal redundancies in the implementation to meet such requirements. With increasing complexity of such systems and considering the large number of components in such systems, redundancy allocation requires a formal scientific basis. In this work, we profess the analysis of the redundancy requirement upfront with the objective of making it an integral part of the specification. The underlying problem is one of synthesizing a formal specification with built-in redundancy artifacts, from the formal properties of the error-free system, the error probabilities of the control components, and the reliability target. We believe that upfront formal analysis of redundancy requirements is important in budgeting the resource requirements from a cost versus reliability perspective. Several case-studies from the automotive domain highlight the efficacy of our proposal.     

亲子互动中游戏参与方式、情感交流和儿童心理理论的关系

本研究通过亲子互动游戏观察来考查亲子游戏参与方式、情感交流与儿童心理理论发展的关系。实验结果如下:第一,控制了年龄因素后,儿童的亲子游戏参与方式中的主动参与和建议游戏两种方式与儿童心理理论发展之间存在显著的相关;而对于母亲来说,指导游戏的参与方式和儿童心理理论发展存在显著相关。第二,控制了年龄因素之后,儿童情感交流方面的分享积极情感和心理理论发展之间存在显著相关。而母亲这方面的指标和儿童心理理论发展没有显著相关。文章对上述结果进行了分析讨论。     

具身视角下的社会认知

摘 要：由于第一代认知科学存在着身心剥离的缺憾,具身化作为第二代认知科学的主要特征得到研究者的广泛关注,并且得到了来自神经科学领域的支持。随着研究的深入,具身学派提出,社会认知是否也应是具身的。现有研究发现具身性对个体评价、反应速度、言语理解、人际交往等方面都有不小的作用。但上述以身体模拟为主的证据仍不足以证明社会认知是具身的,具身学派还需解决诸如明确具身的定义、实验论证、明显区别于传统认知观等问题。
