Relationship between reaction time variability and motor skill development in ADHD

Slower and more variable reaction times to computerized tasks have been documented in children diagnosed with attention deficit/hyperactivity disorder (ADHD). Recent research supports a role for attentional lapses in generating abnormally variable and slow responses. However, given the association between ADHD and impairments in motor control, we hypothesized that slower or more variable reaction times might also correlate with motor development. The aim of this case-control study was to explore the relationship between motor function, reaction speed and variability, and ADHD. After comprehensive educational and clinical assessments, motor skill development was evaluated in 35 children ages 9 to 14 (19 with ADHD) using the Physical and Neurological Examination for Subtle Signs (PANESS) test battery. Finger-sequencing speed and variability were quantified with goniometers. Reaction times were measured with 20 trials each of computerized simple and choice (binary) tasks. Compared to healthy controls, children with ADHD had slower and more variable reaction times, and these findings correlated with impaired motor development (PANESS) and slow and variable finger sequencing (goniometers). Further studies of motor development in ADHD may identify factors influencing speed and variability of reaction times.     

Mental visualization of objects from cross-sectional images

We extended the classic anorthoscopic viewing procedure to test a model of visualization of 3D structures from 2D cross-sections. Four experiments were conducted to examine key processes described in the model, localizing cross-sections within a common frame of reference and spatiotemporal integration of cross sections into a hierarchical object representation. Participants used a hand-held device to reveal a hidden object as a sequence of cross-sectional images. The process of localization was manipulated by contrasting two displays, in situ vs. ex situ, which differed in whether cross sections were presented at their source locations or displaced to a remote screen. The process of integration was manipulated by varying the structural complexity of target objects and their components. Experiments 1 and 2 demonstrated visualization of 2D and 3D line-segment objects and verified predictions about display and complexity effects. In Experiments 3 and 4, the visualized forms were familiar letters and numbers. Errors and orientation effects showed that displacing cross-sectional images to a remote display (ex situ viewing) impeded the ability to determine spatial relationships among pattern components, a failure of integration at the object level.     

The impact of development of population-based study in the biomedical field on laws and regulations: a cross-strait experience on biobank development

Together with the completion of the Human Genome Project, biomedical research has marched into the "Post-Genomic Era." In order to take advantage of this extracted gene related information extensively and precisely so as to realize man's biological phenomena as well as the mechanism of pathogenesis, consequentially, a large scale sample collection of different geological areas and/or ethnic groups becomes necessary for the future population based genetic research of a country and, in turn, the construction of population-based genetic database (Biobank). In recent years, both mainland China and Taiwan have not only made great progress in information and computation technologies, but have also gradually taken a close look into the quality of medicine delivery. Thus, it becomes unavoidable for both sides to create each one's population-based genetic databases (Biobank). Theoretically speaking, the Biobank development shall benefit the study on the correlation between genes and disease and also the solution for disease treatment as well. At the same time, medical diagnostic technology has also been significantly improved. It is believable that the population-based genetic database might be utilized to promote medical quality and to reduce the cost of public health delivery. Further; in the near future, it might become the "raw materials "for medical research application. However when taking promotion of public welfare as the premises for a Biobank development, the severe and multi challenge occurred against the traditional legal rules in terms of the privacy protection, public trust development, the compliance of informed consent principle, the implementation of benefit-sharing doctrine and the possible discrimination concern about the population/participants selection and some other ELSI issues. In this paper, the major legal issues encountered by the Biobank development will first be reviewed accompanied by the background information concerning the Biobank development scenario crossing the Taiwan Strait. Also, mainly following the realm of comparative policy or legal approaches, the paper learning from the fruits of this comparative study, tries to propose some recommendations for future legislative consideration by both mainland China and Taiwan. It's been this author's wish that, when establishing a large scale population based Biobank, the promotion of public trust shall be placed as the primary goal together with the emphasis on supporting publicity and transparency on the administrative practices, so as to encourage the public participation in observing the principle of altruism and, in turn, benefit the future biomedicine development.

面试中的AIM问题及改进对策

面试、尤其是结构化面试是企业、政府机关及一些非盈利性组织选拔人才的最常用的工具。随着应聘者的面试经验增加,面试选拔优秀人才的难度也在增加。本文借鉴国外“印象控制”（AIM）概念,就如何克服主试者的主观偏见、第一印象偏见、次序对比偏见等面试误差、提高面试的信度和效度作了探索。     

视角在时间语言理解中的影响

语言学家在英语的时间语言表达中发现了隐含其中的两种不同运动视角：一种是从过去指向将来的自我运动（自我运动视角moving-ego）;另一种是从将来指向过去的时间运动（时间运动视角moving-time）。心理学家McGlone＆Harding报告了在英语中视角对时问语言理解的作用,并提出人们存在MT视角的偏向。本文报告了两个实验,实验1直接运用和修改McGlone＆Harding的范式在汉语文本探讨视角对时间语言理解的影响。实验2运用信号检测理论来验证了人们存在MT视角偏向。     

元代净明道与朱、陆之学关系略论

本文就元代净明道所受朱熹、陆九渊学说的影响进行了探讨,以为:朱、陆学说之所以能对元代净明道产生巨大影响,乃与其多活动于江西有着密切的关系;元代净明道的宇宙观实多吸取了朱熹之学,而其修行论则多受到了陆九渊之学的影响.但是,净明道并未能很好地消化朱、陆之学说,由此而导致了其思想体系中的一些矛盾.

青少年的同伴依恋与其互联网使用的关系

青少年期同伴群体的支持逐渐超过了父母的影响.青少年期同伴依恋在青少年认知、情感、人格以及行为的健康发展和社会适应中起着重要作用,拥有亲密的同伴关系的青少年出现情感问题和行为问题的可能性更小,并拥有更健康的青少年期适应能力.该研究采用同伴依恋量表、互联网服务使用状况量表以及青少年病理性互联网使用量表对405名中学生进行了问卷调查.旨在探讨青少年同伴依恋与其互联网使用之间的关系.结果表明: (1)同伴信任与社交和娱乐服务的使用偏好呈负相关,尽管都没有达到统计显著性; (2)同伴沟通可以正向预测青少年对信息、娱乐和社交服务的使用偏好,且都达到显著性水平;还可以通过互联网娱乐服务使用偏好间接预测PIU; (3)青少年与同伴的疏离程度可以正向预测青少年对社交服务的使用偏好,也可以直接正向预测PIU.
