Can the output of human cognition be predicted from the assumption that it is an optimal response to the information-processing demands of the environment? A methodology called rational analysis is described for deriving predictions about cognitive phenomena using optimization assumptions. The predictions flow from the statistical structure of the environment and not the assumed structure of the mind. Bayesian inference is used, assuming that people start with a weak prior model of the world which they integrate with experience to develop (...) stronger models of specific aspects of the world. Cognitive performance maximizes the difference between the expected gain and cost of mental effort. Memory performance can be predicted on the assumption that retrieval seeks a maximal trade-off between the probability of finding the relevant memories and the effort required to do so; in categorization performance there is a similar trade-off between accuracy in predicting object features and the cost of hypothesis formation; in casual inference the trade-off is between accuracy in predicting future events and the cost of hypothesis formation; and in problem solving it is between the probability of achieving goals and the cost of both external and mental problem-solving search. The implemention of these rational prescriptions in neurally plausible architecture is also discussed. (shrink)

By utilizing new information from both clinical and experimental (lesion, electrophysiological, and gene-activation) studies with animals, the anatomy underlying anterograde amnesia has been reformulated. The distinction between temporal lobe and diencephalic amnesia is of limited value in that a common feature of anterograde amnesia is damage to part of an comprising the hippocampus, the fornix, the mamillary bodies, and the anterior thalamic nuclei. This view, which can be traced back to Delay and Brion (1969), differs from other recent models in (...) placing critical importance on the efferents from the hippocampus via the fornix to the diencephalon. These are necessary for the encoding and, hence, the effective subsequent recall of episodic memory. An additional feature of this hippocampalanterior thalamic and the perirhinal–medial dorsal thalamic systems are compromised, leading to severe deficits in both recall and recognition. (shrink)

Uses case studies of evil, the most serious of our moral Problems, to explain why people act with cruelty, greed, prejudice and fanatacism.

The appropriate methodology for psychological research depends on whether one is studying mental algorithms or their implementation. Mental algorithms are abstract specifications of the steps taken by procedures that run in the mind. Implementational issues concern the speed and reliability of these procedures. The algorithmic level can be explored only by studying across-task variation. This contrasts with psychology's dominant methodology of looking for within-task generalities, which is appropriate only for studying implementational issues.The implementation-algorithm distinction is related to a number of (...) other “levels” considered in cognitive science. Its realization in Anderson's ACT theory of cognition is discussed. Research at the algorithmic level is more promising because it is hard to make further fundamental scientific progress at the implementational level with the methodologies available. Protocol data, which are appropriate only for algorithm-level theories, provide a richer source than data at the implementational level. Research at the algorithmic level will also yield more insight into fundamental properties of human knowledge because it is the level at which significant learning transitions are defined.The best way to study the algorithmic level is to look for differential learning outcomes in pedagogical experiments that manipulate instructional experience. This provides control and prediction in realistically complex learning situations. The intelligent tutoring paradigm provides a particularly fruitful way to implement such experiments.The implications of this analysis for the issue of modularity of mind, the status of language, research on human/computer interaction, and connectionist models are also examined.

A scholarly edition of The Clarendon Edition of the Works of John Locke: Some Thoughts Concerning Education by John W. Yolton and Jean S. Yolton. The edition presents an authoritative text, together with an introduction, commentary notes, and scholarly apparatus.

There are many reasons why scientific experts may mask disagreement and endorse a position publicly as “jointly accepted.” In this paper I consider the inner workings of a group of scientists charged with deciding not only a technically difficult issue, but also a matter of social and political importance: the maximum acceptable dose of radiation. I focus on how, in this real world situation, concerns with credibility, authority, and expertise shaped the process by which this group negotiated the competing virtues (...) of reaching consensus versus reporting accurately the nature and degree of disagreement among them.

Newell proposed that cognitive theories be developed in an effort to satisfy multiple criteria and to avoid theoretical myopia. He provided two overlapping lists of 13 criteria that the human cognitive architecture would have to satisfy in order to be functional. We have distilled these into 12 criteria: flexible behavior, real-time performance, adaptive behavior, vast knowledge base, dynamic behavior, knowledge integration, natural language, learning, development, evolution, and brain realization. There would be greater theoretical progress if we evaluated theories by a (...) broad set of criteria such as these and attended to the weaknesses such evaluations revealed. To illustrate how theories can be evaluated we apply these criteria to both classical connectionism and the ACT-R theory. The strengths of classical connectionism on this test derive from its intense effort in addressing empirical phenomena in such domains as language and cognitive development. Its weaknesses derive from its failure to acknowledge a symbolic level to thought. In contrast, ACT-R includes both symbolic and subsymbolic components. The strengths of the ACT-R theory derive from its tight integration of the symbolic component with the subsymbolic component. Its weaknesses largely derive from its failure, as yet, to adequately engage in intensive analyses of issues related to certain criteria on Newell's list. Key Words: cognitive architecture; connectionism; hybrid systems; language; learning; symbolic systems. (shrink)

The first book to present Gilles Deleuze's philosophy in language the nonphilosopher can understand.

E. S. de Beer>'s eight-volume edition of the correspondence of John Locke is a classic of modern scholarship. The intellectual range of the correspondence is universal, covering philosophy, theology, medicine, history, geography, economics, law, politics, travel and botany. This first volume covers the years 1650 to 1679.

Applies Deleuzian theory to an array of physical phenomena, scientific issues, and political events. Life, War, Earth demonstrates how Gilles Deleuze’s ontology of the virtual, intensive, and actual can enhance our understanding of important issues in cognitive science, biology, and geography. The book offers a unique reading of Deleuze’s corpus and a useful method for applying Deleuzian techniques to the natural sciences, the social sciences, political phenomena, and contemporary events.

n 1695 John Locke published The Reasonableness of Christianity, an enquiry into the foundations of Christian belief. He did so anonymously, to avoid public involvement in the fiercely partisan religious controversies of the day. In the Reasonableness Locke considered what it was to which allChristians must assent in faith; he argued that the answer could be found by anyone for themselves in the divine revelation of Scripture alone. He maintained that the requirements of Scripture were few and simple, and (...) therefore offered a basis for tolerant agreement among all Christians, and thepromise of peace, stability, and security through toleration. This is the first critical edition of the Reasonableness: for the first time an authoritative annotated text is presented, with full information about sources, variants, amendments, and the publishing history of the work. Also provided in the editorial notes are cross-references, references to otherworks by Locke, definitions of terms, and other information conducive to an understanding of the text.Though modern interest has focused particularly on Locke's philosophy and political theory, increasing attention is being paid to his religious thought. These different strands cannot be understood properly in isolation from each other: so the broader aim of this edition is to help towards animproved understanding of his religious thought in the context of his work as a philosopher, political theorist, and exponent of religious toleration. In his editorial introduction John Higgins-Biddle investigates how Locke's ideas developed, and offers a critical assessment of the three maincontemporary and subsequent interpretations of Locke's religious thought, all of which are shown to be unsatisfactory.

Much of cognitive psychology focuses on effects measured in tens of milliseconds while significant educational outcomes take tens of hours to achieve. The task of bridging this gap is analyzed in terms of Newell's (1990) bands of cognition—the Biological, Cognitive, Rational, and Social Bands. The 10 millisecond effects reside in his Biological Band while the significant learning outcomes reside in his Social Band. The paper assesses three theses: The Decomposition Thesis claims that learning occurring at the Social Band can be (...) reduced to learning occurring at lower bands. The Relevance Thesis claims that instructional outcomes at the Social Band can be improved by paying attention to cognition at the lower bands. The Modeling Thesis claims that cognitive modeling provides a basis for bridging between events on the small scale and desired outcomes on the large scale. The unit-task level, at the boundary of the Cognitive and Rational Bands, is useful for assessing these theses. There is good evidence for all three theses in efforts that bridge from the unit-task level to educational applications. While there is evidence for the Decomposition Thesis all the way down to the 10 millisecond level, more work needs to be done to establish the Relevance Thesis and particularly the Modeling Thesis at the lower levels.

THIS VOLUME owcs its existence to the suggestion and the persuasive insistence of my friend and colleague Justus Buchler... the unpublished papers dealing with "the theory of history" and “the theory of nature” bulked large enough to form a volume in themselves. Hence the volume appears ...with [these] essays in philosophic analysis of two themes that have for some years been central in my own interests. -/- Each of the two Parts deals with a unified theme, and the two together (...) not only exhibit, it is hoped, a consistent philosophic attitude and approach, but also treat two different aspects of what is a common metaphysical inquiry. Aside from the prologue and the epilogue, none of these papers has appeared in this form before... History and nature together offer the great challenge to the philosophic mind.

[v. 1] From the Middle Ages to the Enlightenment.--v. 2. From the German Enlightenment to the age of Darwin.

This article surveys recent scholarship on Confucian role ethics, examines some of its fundamental commitments, and suggests future directions for scholarship. Role ethics interprets early Confucianism as promoting a relational conception of persons and employs this conception to emphasize how a person's roles and relationships are the source of her ethical obligations and ethical growth. While there is much consensus among role ethic scholars, they disagree over the role of theory in further explicating the view and about the metaphysical basis (...) of relational persons. Strong and moderate versions of role ethics emerge, and the article explores the strengths and weaknesses of both. (shrink)
