A computerized test of self-control predicts classroom behavior

We assessed choices on a computerized test of self-control (CTSC) for a group of children with features of attention deficit hyperactivity disorder (ADHD) and a group of controls. Thirty boys participated in the study. Fifteen of the children had been rated by their parents as hyperactive and inattentive, and 15 were age- and gender-matched controls in the same classroom. The children were observed in the classroom for three consecutive mornings, and data were collected on their activity levels and attention. The CTSC consisted of two tasks. In the delay condition, children chose to receive three rewards after a delay of 60 s or one reward immediately. In the task-difficulty condition, the children chose to complete a difficult math problem and receive three rewards or complete an easier problem for one reward. The children with ADHD features made more impulsive choices than their peers during both conditions, and these choices correlated with measures of their activity and attention in the classroom.     

腹腔镜下胃转流术治疗2型糖尿病的疗效分析及可行性研究

胃转流术治疗重度肥胖由来已久.近年来,国内研究通过接受胃转流术的肥胖患者的长期随访后发现,胃转流术可长期、稳定的缓解2型糖尿病,并能减少糖尿病并发症,为2型糖尿病的外科治疗开辟了新途径.本文总结我院32例接受腹腔镜胃转流术的2型糖尿病患者术后随访情况,分析后认为腹腔镜下胃转流术治疗2型糖尿病疗效显著,具有微创、安全、有效的特点,是2型糖尿病治疗方法的一种补充和完善,值得临床推广.     

心理信息学:网络信息时代下的心理学新发展

在见证了社会计算与计算社会科学的勃兴之后,心理学和信息科学在网络信息时代相遇,催生出心理信息学这门新兴交叉学科。该学科旨在利用计算机与信息科学技术,通过开展网络调查和实验、开发和利用移动设备、建立数据库和分类体系、使用开源软件和数据挖掘技术等,获取、整理和分析心理学研究资料。其对大规模复杂数据的掌控能力,使心理学家可以从新的高度和视野,针对现实和虚拟网络中的个体与群体心理现象展开研究,重新检视已有理论假设并探索新发现。但是,心理信息学在展现巨大潜力的同时,也在技术和研究设计、伦理和研究规范、研究重心与人才培养等诸多方面面临挑战。     

Molar versus as a paradigm clash.

The molar view of behavior arose in response to the demonstrated inadequacy of explanations based on contiguity. Although Dinsmoor's (2001) modifications to two-factor theory render it irrefutable, a more basic criticism arises when we see that the molar and molecular views differ paradigmatically. The molar view has proven more productive.     

The Relevance of Tillich for the Theology and Science Dialogue

This paper explores the relevance of the theology of Paul Tillich for the contemporary dialogue with the natural sciences. The focus is on his Systematic Theology , volume I. First I discuss the general relevance of Tillich's methodology (namely, the method of correlation) for that dialogue, stressing that a genuine dialogue requires cognitive input from both sides and that both sides find "value added" according to their own criteria (or what I call the method of "mutual creative interaction"). Then I move specifically to a Tillichian theological analysis of twentieth-century theoretical science and its empirical discoveries, including Big Bang, inflationary, and quantum cosmologies, quantum physics, thermodynamics, chaos and complexity, and molecular and evolutionary biology, suggesting how they relate to such Tillichian themes as finitude and the categories of being and knowing (time, space, causality, and substance) and to Tillich's understanding of such symbols as God, freedom and destiny, creation, and estrangement. In doing so, my intention is to provide a point of departure for further extended analyses of Tillich's theology in relation to contemporary natural science.
