Fourteen subjects were tape-recorded while they undertook to find a law to summarize numerical data they were given. The source of the data was not identified, nor were the variables labeled semantically. Unknown to the subjects, the data were measurements of the distances of the planets from the sun and the periods of their revolutions about it—equivalent to the data used by Johannes Kepler to discover his third law of planetary motion. Four of the 14 subjects discovered the same law as Kepler did (the period varies as the 3/2 power of the distance), and a fifth came very close to the answer. The subiects' protocols provide a detailed picture of the problem-solving searches they engaged in, which were mainly, but not exclusively, in the space of possible functions for fitting the data, and provide explanations as to why some succeeded and the others failed. The search heuristics used by the subjects are similar to those embodied in the BACON program, computer simulation of certain scientific discovery processes. The experiment demonstrates the feasibility of examining some of the processes of scientific discovery by recreating, in the laboratory, discovery situations of substantial historical relevance. It demonstrates also, that under conditions rather similar to those of the original discoverer, a law can be rediscovered by persons of ordinary intelligence (i.e., the intelligence needed for academic success in a good university). The data for the successful subjects reveal no “creative” processes in this kind of a discovery situation different from those that are regularly observed in all kinds of problem-solving settings. 相似文献

The paradox of pain is that pain is in some ways like a bodily state and in other ways like a mental state. You can have a pain in your shin, but there is no denying that you are in pain if it feels like you are. How can a state be both in your shin and in your mind? Evaluativism is a promising answer. According to evaluativism, an experience of pain in your shin represents that there is a disturbance in your shin, and that it is bad that this disturbance is there. Thus, the experience brings you to tend to your shin by telling you something about the state of your shin. But the paradox of pain still confronts evaluativism in the form of the killing the messenger objection: The evaluativist has a nice story about our body‐directed responses to pain, like tending to wounds, but this story does not explain responses to pain, like taking painkillers, that seem to be experience‐directed. Evaluativists have offered accounts of experience‐directed responses to pain, but I will argue that these accounts conflict with the Transparency thesis—the claim that we can only access our experiences inferentially. Evaluativism and Transparency are natural bedfellows, so this is a problem for evaluativists. Having argued as much, I will go on to develop a new evaluativist account of taking painkillers, which does not conflict with Transparency. I call it naïve evaluativism. According to naïve evaluativism, we experience painkillers as making tissue damage or disruption less bad, and absent further reflection, that is, why we take them. 相似文献

The representations that underlie our ability to read must encode not only the identities of the letters in a word, but also
their relative positions. In recent years, many new proposals have been advanced concerning the representation of letter position
in reading, but the available data do not distinguish among the competing proposals; multiple theories, each positing a different
letter position representation scheme, are compatible with the evidence. In this article, we report two experiments that used
the illusory word paradigm (e.g., Davis & Bowers, Journal of Experimental Psychology: Human Perception and Performance, 30:
923–941, 2004) to distinguish among alternative schemes for representing letter position in reading. The results support a scheme that
uses both the beginning and the end of a word as anchoring points. This both-edges scheme has been implicated in letter position
representation in spelling (Fischer-Baum, McCloskey, & Rapp, Cognition, 115: 466–490, 2010), as well as in position representation in verbal working memory (Henson, Memory & Cognition, 27: 915–927, 1999), suggesting that it may be a domain-general scheme for representing position in a sequence. 相似文献
