条件位置范式在疼痛研究领域的应用

在疼痛领域,基础研究传统上主要关注疼痛的感觉维度和诱发痛的机制,对疼痛的情绪维度和临床上更常见的自发痛研究较少,这造成了基础研究和临床应用的脱节.条件位置范式的诞生在一定程度上解决了这一问题.条件位置范式是研究药物奖赏和成瘾的经典范式.近10年来,它开始被应用到疼痛研究领域.本文系统总结了目前条件位置范式在疼痛领域的研究进展,主要包括应用条件位置厌恶范式研究疼痛情绪、应用条件位置偏爱范式探索自发痛机制以及进行镇痛药物筛选.最后,结合已有的研究,提出了未来条件位置范式在疼痛领域的应用方向.     

Mathematics and Theology: A Stroll through the Garden of Mathaphors

Mathematics has long been considered the language of science and has even been acknowledged as the universal language of the future. Yet mathematics also plays a less-recognized religious role in that metaphors drawn from mathematics (mathaphors) can influence our spiritual perspectives by helping us to entertain new religious ideas and to challenge old ones. Mathaphors are therefore useful tools in matheology (the study of mathematics and theology). This essay explores ten ways in which contemporary mathaphors affect our spiritual lives. Specifically, mathaphors are: changing our metaphors for God; challenging our human role in the universe; helping us accept ambiguity; revamping our understanding of the one and the many; revising our thoughts about free will and determinism; moving us toward pluralistic, multi-world views; pushing the envelope on what consciousness is; altering our expectations for afterlife; offering the hope of a more compassionate future; encouraging faith perspectives that are always incomplete and in process.     

Scientific Philosophy,Mathematical Philosophy,and All That

This article suggests that scientific philosophy, especially mathematical philosophy, might be one important way of doing philosophy in the future. Along the way, the article distinguishes between different types of scientific philosophy; it mentions some of the scientific methods that can serve philosophers; it aims to undermine some worries about mathematical philosophy; and it tries to make clear why in certain cases the application of mathematical methods is necessary for philosophical progress.     

Good and Bad Years: An Index of American Social,Economic, and Political Threat (1920–1986)

Information provided by 196 U.S. history professors, indicating the degree to which they considered each of the years from 1920 to 1986 threatening to the established order and way of life in America, was pooled to form a social, economic, and political threat (SEPT) index. Interrater reliability was high, and substantial test-retest reliability was evident for a selected subsample over a 6-month period. The index significantly correlated with 11 objective indices of threat, including the suicide rate, unemployment rate, rise and fall of common stocks, and number of military men on active duty. Several studies involving threat and authoritarianism were replicated and in some instances extended with the SEPT index (McCann & Stewin, 1984; Sales, 1972, 1973). The pseudo-archival SEPT index has utility when relatively global estimates of prevailing threat are required for historiometric research testing a diversity of hypotheses gleaned from psychological, sociological, historical, and political science theories.     

Henri Bergson: Evolution,time and philosophy

Evolutionary theory is hindered by the conflict between the apparently antagonistic principles of its two founding figures, Darwin and Lamarck. Bergson's Creative Evolution outlines the means of transcending this impasse. If the evolutionary process is conceived as enduring then the atomistic model of static genetic states is never fully realisable. In the light of this, Bergson considers the germ‐plasm to be essentially “fluid.” If there is to be influence on the germ‐line it will be primarily in terms of the manner in which the genetic data is unfolded. In order to designate this influence Bergson introduces the concept of the “tendency.” The tendency will be explicated in relation to contemporary evolutionary biology. However, as the concept signifies that which is given only in the duration in which information is elaborated, it is precluded from representation. Bergson demonstrates that it is the evolutionary principle of continuous transformation which constitutes the limit to any scientific of view. For this reason, science needs to be complemented by a philosophical account of the duration of process.     

Scientific Understanding and Mathematical Abstraction

This paper argues for two related theses. The first is that mathematical abstraction can play an important role in shaping the way we think about and hence understand certain phenomena, an enterprise that extends well beyond simply representing those phenomena for the purpose of calculating/predicting their behaviour. The second is that much of our contemporary understanding and interpretation of natural selection has resulted from the way it has been described in the context of statistics and mathematics. I argue for these claims by tracing attempts to understand the basis of natural selection from its early formulation as a statistical theory to its later development by R.A. Fisher, one of the founders of modern population genetics. Not only did these developments put natural selection of a firm theoretical foundation but its mathematization changed the way it was understood as a biological process. Instead of simply clarifying its status, mathematical techniques were responsible for redefining or reconceptualising selection. As a corollary I show how a highly idealised mathematical law that seemingly fails to describe any concrete system can nevertheless contain a great deal of accurate information that can enhance our understanding far beyond simply predictive capabilities.

Age, memory load, and individual differences in working memory as determinants of class-inclusion reasoning.

We studied the effects of individual differences in speak-span scores and variations in memory demands on the class-inclusion performance of 10-, 13-, and 15-year-old children. The speak-span task was an age-appropriate modification of Daneman and Carpenter's (1980) reading-span task and was considered to be a measure of global resources. The age variable was assumed to be a global index of skill development, and some of the specific skills hypothesized to be important in class-inclusion reasoning were estimated using a mathematical model. The results from both regression analyses and the mathematical model indicated that differences in age, speak span, and memory load all affected performance. Surprisingly, the effects of speak span and memory load were independent. However, the effects of each of these variables depended on the age level of the participants. Based on these findings, we argued that (a) resources vary continuously with age, (b) both skill level and global resources should be varied in developmental studies of problem solving, and (c) resource theories (e.g., Norman & Shallice, 1986) should be modified to account for developmental change.
