A number of theoretical positions in psychology—including variants of case‐based reasoning, instance‐based analogy, and connectionist models—maintain that abstract rules are not involved in human reasoning, or at best play a minor role. Other views hold that the use of abstract rules is a core aspect of human reasoning. We propose eight criteria for determining whether or not people use abstract rules in reasoning, and examine evidence relevant to each criterion for several rule systems. We argue that there is substantial evidence (...) that several different inferential rules, including modus ponens, contractual rules, causal rules, and the law of large numbers, are used in solving everyday problems. We discuss the implications for various theoretical positions and consider hybrid mechanisms that combine aspects of instance and rule models. (shrink)

The authors examined cultural preferences for formal versus intuitive reasoning among East Asian (Chinese and Korean), Asian American, and European American university students. We investigated categorization (Studies 1 and 2), conceptual structure (Study 3), and deductive reasoning (Studies 3 and 4). In each study a cognitive conflict was activated between formal and intuitive strategies of reasoning. European Americans, more than Chinese and Koreans, set aside intuition in favor of formal reasoning. Conversely, Chinese and Koreans relied on intuitive strategies more than (...) European Americans. Asian Americans' reasoning was either identical to that of European Americans, or intermediate. Differences emerged against a background of similar reasoning tendencies across cultures in the absence of conflict between formal and intuitive strategies. (shrink)

There is a continuum between prototypical cases of rule use and prototypical cases of similarity use. A prototypical rule: (1) is explicitly represented, (2) can be verbalized, and (3) requires that the user selectively attend to a few features of the object, while ignoring the others. Prototypical similarity-use requires that: (1) the user should match the object to a mental representation holistically, and (2) there should be no selective attention or inhibition. Neural evidence supports prototypical rule-use. Most models of categorization (...) fall between the two prototypes. (shrink)

Many neuroimaging studies of semantic memory have argued that knowledge of an object's perceptual properties are represented in a modality-specific manner. These studies often base their argument on finding activation in the left-hemisphere fusiform gyrus-a region assumed to be involved in perceptual processing-when the participant is verifying verbal statements about objects and properties. In this paper, we report an extension of one of these influential papers-Kan, Barsalou, Solomon, Minor, and Thompson-Schill (2003 )-and present evidence for an amodal component in the (...) representation and processing of perceptual knowledge. Participants were required to verify object-property statements (e.g., "cat-whiskers?"; "bear-wings?") while they were being scanned by functional magnetic resonance imaging (fMRI). We replicated Kan et al.'s activation in the left fusiform gyrus, but also found activation in regions of left inferior frontal gyrus (IFG) and middle-temporal gyrus, areas known to reflect amodal processes or representations. Further, only activations in the left IFG, an amodal area, were correlated with measures of behavioural performance. (shrink)

We advance a model of human probability judgment and apply it to the design of an extrapolation algorithm. Such an algorithm examines a person's judgment about the likelihood of various statements and is then able to predict the same person's judgments about new statements. The algorithm is tested against judgments produced by thirty undergraduates asked to assign probabilities to statements about mammals.

Establishing reasonable, prior distributions remains a significant obstacle for the construction of probabilistic expert systems. Human assessment of chance is often relied upon for this purpose, but this has the drawback of being inconsistent with axioms of probability. This article advances a method for extracting a coherent distribution of probability from human judgment. The method is based on a psychological model of probabilistic reasoning, followed by a correction phase using linear programming.

Some decades ago in his intriguing book on Jonathan Edwards, Perry Miller used to great effect the device of supposing a two-fold biography of Edwards, an external one consisting of the historical record embracing the major events of his life and times, and an internal one aimed at an interpretation of the mind of Edwards and the development of his thought.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Jonathan Edwards's Philosophy of History: The Reenchantment of the World in the Age of EnlightenmentJohn E. SmithAvihu Zakai. Jonathan Edwards's Philosophy of History: The Reenchantment of the World in the Age of Enlightenment. Princeton: Princeton University Press, 2003. Pp. xvii + 348. Cloth, $49.95.Edwards's History of Redemption is the focus of this study by Avihu Zakai—Professor of History at the Hebrew University in Jerusalem. The History is a (...) series of thirty sermons Edwards preached on Isaiah 51:8 "... my righteousness shall be forever... my salvation from generation to generation." For him, it was a "new method in divinity... thrown into the form of a history"—a narrative showing God's sovereignty in redemption "from the fall of man to the end of the world."Zakai gives a comprehensive account of Edwards's view of history meant to highlight his struggle against modern beliefs threatening Christian faith (308; passim). The discussion is not limited to history, but includes most of Edwards's writing from 1720-1750 with emphasis on his opposition to the Enlightenment. Zakai cannot interpret so many works with the accuracy needed; he repeats old errors such as opposing the "head" and "heart" in the Affections and minimizing Edwards's respect for "common morality" in the ethical writings. Zakai is right in saying that Edwards insisted on God's authority over the world and history, but he puts it in such absolutistic terms that he often seems to abandon historical analysis in favor of exhortation.Zakai's best contribution is in his search for the general framework of God's redemption of the "engine" driving history (120ff.; 213ff.). He finds the answer in "seasons" of revival such as the Great Awakening. This is true, but Edwards notes other special events like the Reformation that "promoted the work of redemption" (Works, 9. 272), but are not revivals in the usual sense. For Edwards, special events are of many kinds and are identified by interpretation based on God's Providence. As Miller claimed, interpretation is essential; without it we may have a chronicle of events, but no history. Zakai seems to underestimate this point and the many problems it poses.The book strikes me as one more attempt—George Marsden's recent book, Jonathan Edwards: A Life (New Haven, 2003), is another—to rescue Edwards from "profane" interpreters like Miller who saw that Edwards learned from the Enlightenment even though he challenged many of its ideas. In my view, Edwards can well take care of himself.John E. SmithYale UniversityCopyright © 2004 Journal of the History of Philosophy, Inc.... (shrink)

Scholars of classical philosophy have long disputed whether Aristotle was a dialectical thinker. Most agree that Aristotle contrasts dialectical reasoning with demonstrative reasoning, where the former reasons from generally accepted opinions and the latter reasons from the true and primary. Starting with a grasp on truth, demonstration never relinquishes it. Starting with opinion, how could dialectical reasoning ever reach truth, much less the truth about first principles? Is dialectic then an exercise that reiterates the prejudices of one's times and at (...) best allows one to persuade others by appealing to these prejudices, or is it the royal road to first principles and philosophical wisdom? In From Puzzles to Principles? May Sim gathers experts to argue both these positions and offer a variety of interpretive possibilities. The contributors' thoughtful reflections on the nature and limits of dialectic should play a crucial role in Aristotelian scholarship. (shrink)
