Counterfactual and prefactual conditionals. 总被引:1,自引:0,他引:1
We consider reasoning about prefactual possibilities in the future, for example, "if I were to win the lottery next year I would buy a yacht" and counterfactual possibilities, for example, "if I had won the lottery last year, I would have bought a yacht." People may reason about indicative conditionals, for example, "if I won the lottery I bought a yacht" by keeping in mind a few true possibilities, for example, "I won the lottery and I bought a yacht." They understand counterfactuals by keeping in mind two possibilities, the conjecture, "I won the lottery and I bought a yacht" and the presupposed facts, "I did not win the lottery and I did not buy a yacht." We report the results of three experiments on prefactuals that examine what people judge them to imply, the possibilities they judge to be consistent with them, and the inferences they judge to follow from them. The results show that reasoners keep a single possibility in mind to understand a prefactual. 相似文献

An integrated theory of the mind 总被引:23,自引:0,他引:23
Anderson JR Bothell D Byrne MD Douglass S Lebiere C Qin Y 《Psychological review》2004,111(4):1036-1060
Adaptive control of thought-rational (ACT-R; J. R. Anderson & C. Lebiere, 1998) has evolved into a theory that consists of multiple modules but also explains how these modules are integrated to produce coherent cognition. The perceptual-motor modules, the goal module, and the declarative memory module are presented as examples of specialized systems in ACT-R. These modules are associated with distinct cortical regions. These modules place chunks in buffers where they can be detected by a production system that responds to patterns of information in the buffers. At any point in time, a single production rule is selected to respond to the current pattern. Subsymbolic processes serve to guide the selection of rules to fire as well as the internal operations of some modules. Much of learning involves tuning of these subsymbolic processes. A number of simple and complex empirical examples are described to illustrate how these modules function singly and in concert. 相似文献

Color realism and color science 总被引:8,自引:0,他引:8
The target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically, types of reflectance. This is probably a minority opinion, at least among color scientists. Textbooks frequently claim that physical objects are not colored, and that the colors are "subjective" or "in the mind." The article has two other purposes: First, to introduce an interdisciplinary audience to some distinctively philosophical tools that are useful in tackling the problem of color realism and, second, to clarify the various positions and central arguments in the debate. The first part explains the problem of color realism and makes some useful distinctions. These distinctions are then used to expose various confusions that often prevent people from seeing that the issues are genuine and difficult, and that the problem of color realism ought to be of interest to anyone working in the field of color science. The second part explains the various leading answers to the problem of color realism, and (briefly) argues that all views other than our own have serious difficulties or are unmotivated. The third part explains and motivates our own view, that colors are types of reflectances and defends it against objections made in the recent literature that are often taken as fatal. 相似文献

Dilemmas in military medical ethics since 9/11 总被引:2,自引:0,他引:2
Howe EG 《Kennedy Institute of Ethics journal》2003,13(2):175-188
The attack on the United States by terrorists on 9/11 and the war with Iraq have raised new ethical questions for the military and for military physicians (Herman 2002; Elshtain 2003). How and when attacks may occur now is less predictable. Planes have been hijacked, and persons dressed as civilians may carry bombs to blow themselves and others up. These dangers pose an increased threat, and, thus, there is a need for new defensive measures. How far these measures should go is, however, greatly open to debate. One of the most difficult ethical question raised for the military and military doctors by these developments is what interrogation methods are permissable when questioning captured terrorists. The licitness of different interrogation practices is, however, only one of the ethical problems potentially encountered by military physicians now having to treat terrorists and POWs. The following discussion presents the major concerns regarding this and other issues. 相似文献

Eating disorders are serious mental illnesses affecting a significant proportion of women and a smaller number of men. Approximately half of those with an eating disorder (ED) will not meet the criteria for anorexia or bulimia nervosa, and will be diagnosed with an eating disorder not otherwise specified (EDNOS). Until recently, there were no recommended treatments for EDNOS. This article provides an overview of enhanced cognitive behavior therapy, a validated treatment for all forms of EDs. 相似文献
