Computer- and internet-based psychotherapy interventions

Computers and Internet-based programs have great potential to make psychological assessment and treatment more cost-effective. Computer-assisted therapy appears to be as effective as face-to-face treatment for treating anxiety disorders and depression. Internet support groups also may be effective and have advantages over face-to-face therapy. However, research on this approach remains meager.     

Laboratory of functional neuroelectrical imaging and brain–computer interfacing at Fondazione Santa Lucia

The laboratory of functional neuroelectrical imaging and brain–computer interfacing at Fondazione Santa Lucia is based on the joint work of researchers with a bioengineering and clinical neurophysiology background. The activity is mainly devoted to two aims: the non-invasive investigation of the motor cortical function under physiological and pathological conditions, through the development of advanced processing methods of the electroencephalographic signals; the development of a real-time EEG-based brain–computer interface (BCI) and the study of its use as an aid to enhance (or even to allow) the functional independence of persons with different degrees of motor disability.     

有关智力的遗传研究演进

智力是被行为遗传学广泛研究的重要内容之一。过去十几年问。有关智力的遗传研究超越了最基本的先天与后天之争,通过发展的遗传分析、多变量遗传分析以及对遗传与环境交互作用的探讨获得了许多重要发现。分子遗传学的发展更是为智力研究展开了新的一页,使得确定与特定认知能力有关的基因成为可能。     

论分子生物学时代的生理学探索——微观与宏观的统一

20世纪中期,随着蛋白质空间结构的解析和DNA双螺旋结构的发现,形成了核酸和蛋白质为主要研究对象的分子生物学时代,然而随着科学研究的不断深入微观,越来越多的科学家意识到认为将复杂的生物现象还原称简单的组成部分(细胞或分子)就能充分解释生物现象的观点有失偏颇。分子与整体,微观与宏观必须结合与统一,这一点已显得日益重要和紧迫。由此,生理学作为一门相对古老的研究结构与功能关系,尤其是整体功能的生命学科,在这一时期获得了新的契机。     

Evaluating Merger and Intersection of Equivalence Classes with One Member in Common

Sidman (1994) noted that the existence of a member that is common to more than one class may produce either class merger (union) or class intersection. A multiple-selection, matching-to-sample test was developed to examine the conditions under which these outcomes occur. Test trials each required three conditional discriminations involving selection or rejection of comparison stimuli under control of samples representing two categories. Test results obtained from an initial group of typical adults using familiar stimuli (DOG and BIRD, pictures of dogs and birds and relevant printed breed names (e.g., DALMATIAN, RETRIEVER) showed the conditional stimulus control best described as intersection. For example, the word DALMATIAN provided the context for selecting the dalmatian but not the retriever picture. However, these results may have depended on the participants'' verbal history as English speakers. Would conditional-discrimination training with overlapping sets of laboratory-generated stimuli also result in intersection? Naïve typical adults were assigned to one of three different training conditions. Like the participants tested with familiar stimuli, these participants demonstrated highly reliable test outcomes best described as showing class intersection, regardless of training condition. These findings begin to elucidate the necessary and sufficient conditions for establishing complex category-like classes of stimuli.     

On the Meaning of Screens: Towards a Phenomenological Account of Screenness

This paper presents a Heideggerian phenomenological analysis of screens. In a world and an epoch where screens pervade a great many aspects of human experience, we submit that phenomenology, much in a traditional methodological form, can provide an interesting and novel basis for our understanding of screens. We ground our analysis in the ontology of Martin Heidegger's Being and Time [1927/1962], claiming that screens will only show themselves as they are if taken as screens-in-the-world. Thus, the phenomenon of screen is not investigated in its empirical form or conceptually. It is rather taken as a grounding intentional orientation that conditions our engagement with certain surfaces as we comport ourselves towards them “as screens.” In doing this we claim to have opened up the phenomenon of screen in a new and meaningful way.     

Correlates and stability of alternate stimuli in a computer-based measure of inspection time

Inspection time tasks assess the ability to make a simple visual discrimination, typically in milliseconds. Typically, IT stimuli consists of a pi-shaped figure, in which subjects select the side with the significantly longer leg. To prevent storage in iconic memory, a backward mask is then introduced. However, some participants have reported that the mask may cause the shorter leg to appear to lengthen, creating a possible strategy that facilitates performance. As a result, alternative stimuli/masks have been developed; however, these alternative stimuli may be processed differently. This study assessed the cognitive correlates and stability of an alternative stimuli/mask. Results indicated that processing of the stimuli was influenced by an interaction between the complexity of the stimuli and the number of times it was presented. Specifically, the alternative stimulus/mask produced slower processing, particularly at the time of a second administration; however, it contributed an important and unique relationship with speeded, general intelligence.     

Philosophy for Computers: Some Explorations in Philosophical Modeling

Philosophical modeling has a long and distinguished history, but the computer offers new and powerful prospects for the creation and manipulation of models. It seems inevitable that the computer will become a major tool in future philosophical research. Here I offer an overview of explorations in philosophical computer modeling that we in the Group for Logic and Formal Semantics at SUNY Stony Brook have undertaken: explorations regarding (1) the potential emergence of cooperation in a society of egoists, (2) self-reference and paradox in fuzzy logic, (3) a fractal approach to formal systems, and (4) on-going explorations with models for the emergence of communication. The attempt is not to give a detailed report on any of these but to give a bird s-eye view of them all, emphasizing the general form that the models take, the philosophical motivations behind them, and the kinds of philosophical results that they may have to offer.     

人脑的奥秘能否由人脑自身揭示--浅谈神经科学现代研究方法

神经科学研究是学科、多层次的。神经科学的每一次飞跃几乎都与某种研究方法的出现有关。从形态学的束路追踪法、组织化学法、原位杂交法、其聚焦激光扫描显微镜,到生理学的脑内微透析术、脑片、微电泳及行为学方法;从电生理的电压钳、膜片和脑电波,到生物化学的层析法、放射免疫法、免疫印迹法等;从种类繁多的分子生物学方法到各种脑成像技术。每种新方法的出现都打开了一扇门,引入一个新领域。实践证明,人脑即使不能彻底了解人脑的奥秘,也可无限地逼近。
