Missing from Quartz & Sejnowski's (Q&S's) unique and valuable effort to relate cognitive development to neural constructivism is an examination of the global emergent properties of adding new neural circuits. Such emergent properties can be studied with computational models. Modeling with generative connectionist networks shows that synaptogenic mechanisms can account for progressive increases in children's representational power.

Computer simulations show that an unstructured neural-network model [Shultz, T. R., & Bale, A. C. (2001). Infancy, 2, 501–536] covers the essential features␣of infant learning of simple grammars in an artificial language [Marcus, G. F., Vijayan, S., Bandi Rao, S., & Vishton, P. M. (1999). Science, 283, 77–80], and generalizes to examples both outside and inside of the range of training sentences. Knowledge-representation analyses confirm that these networks discover that duplicate words in the sentences are nearly identical and that (...) they use this near-identity relation to distinguish sentences that are consistent or inconsistent with a familiar grammar. Recent simulations that were claimed to show that this model did not really learn these grammars [Vilcu, M., & Hadley, R. F. (2005). Minds and Machines, 15, 359–382] confounded syntactic types with speech sounds and did not perform standard statistical tests of results. (shrink)

The Page target article is interesting because of apparent coverage of many psychological phenomena with simple, unified neural techniques. However, prototype phenomena cannot be covered because the strongest response would be to the first-learned stimulus in each category rather than to a prototype stimulus or most frequently presented stimuli. Alternative methods using distributed coding can also achieve portability of network knowledge.

Neuroconstructivist modeling can be usefully extended with algorithms that build their own topology and recruit existing knowledge, effectively constructing a hierarchy of network modules. Possible benefits include allowing abilities to emerge naturally, in a way that affords objective study, deeper insights, and more rapid progress, and provides more serious consideration of the implications of constructivism.

How much would you pay to play a lottery with an “infinite expected payoff?” In the case of the century old, St. Petersburg Paradox, the answer is that the vast majority of people would only pay a small amount. The authors seek to understand this paradox by providing an explanation consistent with a broad, process‐level model of human decision‐making under risk.

We highlight methodological and theoretical limitations of the authors' Dirac formalism and suggest the von Neumann open systems approach as a resolution. The open systems framework is a generalization of classical probability and we hope it will allow cognitive scientists to extend quantum probability from perception, categorization, memory, decision making, and similarity judgments to phenomena in learning and development.

Perruchet & Vinter do not fully resolve issues about the role of consciousness and the unconscious in cognition and learning, and it is doubtful that consciousness has been computationally implemented. The cascade-correlation (CC) connectionist model develops high-order feature detectors as it learns a problem. We describe an extension, knowledge-based cascade-correlation (KBCC), that uses knowledge to learn in a hierarchical fashion.

Clark & Thornton present the well-established principle that recoding inputs can make learning easier. A useful goal would be to make such recoding automatic. We discuss some ways in which incrementality and transfer in connectionist networks could attain this goal.

After presenting the major objections raised against standard formulations of the H-D method of theory testing, I identify what seems to be an important element of truth underlying the method. I then draw upon this element in an effort to develop a plausible formulation of the H-D method which avoids the various objections.

This textbook brings the humanities to students in order to evoke the humanity of students. It helps to form individuals who take charge of their own minds, who are free from narrow and unreflective forms of thought, and who act compassionately in their public and professional worlds. Using concepts and methods of the humanities, the book addresses undergraduate and premed students, medical students, and students in other health professions, as well as physicians and other healthcare practitioners. It encourages them to (...) consider the ethical and existential issues related to the experience of disease, care of the dying, health policy, religion and health, and medical technology. Case studies, images, questions for discussion, and role-playing exercises help readers to engage in the practical, interpretive, and analytical aspects of the material, developing skills for critical thinking as well as compassionate care.

Jean-Paul Sartre was one of the most influential thinkers of the twentieth century. Regarded as the father of existentialist philosophy, he was also a political critic, moralist, playwright, novelist, and author of biographies and short stories. Thomas R. Flynn provides the first book-length account of Sartre as a philosopher of the imaginary, mapping the intellectual development of his ideas throughout his life, and building a narrative that is not only philosophical but also attentive to the political and literary dimensions (...) of his work. Exploring Sartre's existentialism, politics, ethics, and ontology, this book illuminates the defining ideas of Sartre's oeuvre: the literary and the philosophical, the imaginary and the conceptual, his descriptive phenomenology and his phenomenological concept of intentionality, and his conjunction of ethics and politics with an 'egoless' consciousness. It will appeal to all who are interested in Sartre's philosophy and its relation to his life. (shrink)

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: -/- The main aim of this review will be to assess the effects of changing practitioner empathy or patient expectations for all conditions. The main objective is to conduct a systematic review of randomised trials where the intervention involves manipulating either (a) practitioner empathy or (b) patient expectations, or (c) both.

Sartre and Foucault were two of the most prominent and at times mutually antagonistic philosophical figures of the twentieth century. And nowhere are the antithetical natures of their existentialist and poststructuralist philosophies more apparent than in their disparate approaches to historical understanding. A history, thought Foucault, should be a kind of map, a comparative charting of structural transformations and displacements. But for Sartre, authentic historical understanding demanded a much more personal and committed narrative, a kind of interpretive diary of moral (...) choices and risks compelled by critical necessity and an exacting reality. Sartre's history, a rational history of individual lives and their intrinsic social worlds, was in essence immersed in biography. In Volume One of this authoritative two-volume work, Thomas R. Flynn conducts a pivotal and comprehensive reconstruction of Sartrean historical theory, and provocatively anticipates the Foucauldian counterpoint to come in Volume Two. (shrink)

The concept of an ecological niche (econiche) has been used in a variety of ways, some of which are incompatible with a relational or functional interpretation of the term. This essay seeks to standardize usage by limiting the concept to functional relations between organisms and their surroundings, and to revise the concept to include epistemic relations. For most organisms, epistemics are a vital aspect of their functional relationships to their surroundings and, hence, a major determinant of their econiche. Rejecting the (...) traditional dualism of organism and environment, an econiche is defined as the reciprocal (dual) of a functionally specified class of organisms (FSTU). From this perspective, an econiche necessarily implies a certain type of organism, and a class of functionally similar organisms implies a special econiche.The econiche concept is also discussed in relation to other ecological terms that reflect the distributional patterns of organisms, such as habitat, and the concept of an empty niche is criticized.

Adam Smith is respected as the father of contemporary economics for his work on systemizing classical economics as an independent field of study in The Wealth of Nations. But he was also a significant moral philosopher of the Scottish Enlightenment, with its characteristic concern for integrating sentiments and rationality. This article considers Adam Smith as a key moral philosopher of commercial society whose critical reflection upon the particular ethical challenges posed by the new pressures and possibilities of commercial society remains (...) relevant today. The discussion has three parts. First I address the artificial separation between self-interest and morality often attributed to Smith, in which his work on economics is stripped of its ethical context. Second I outline Smith’s ethical approach to economics, focusing on his vigorous but qualified defence of commercial society for its contributions to prosperity, justice, and freedom. Third I outline Smith’s moral philosophy proper as combining a naturalistic account of moral psychology with a virtue ethics based on propriety in commercial society. (shrink)

Sartre and Foucault were two of the most prominent and at times mutually antagonistic philosophical figures of the twentieth century. And nowhere are the antithetical natures of their existentialist and poststructuralist philosophies more apparent than in their disparate approaches to historical understanding. In Volume One of this authoritative two-volume study, Thomas R. Flynn conducted a pivotal and comprehensive reconstruction of Sartrean historical theory. This long-awaited second volume offers a comprehensive and critical reading of the Foucauldian counterpoint. A history, theorized (...) Foucault, should be a kind of map, a comprehensive charting of structural transformations and displacements over time. Contrary to other Foucault scholars, Flynn proposes an "axial" rather than a developmental reading of Foucault's work. This allows aspects of Foucault's famous triad of knowledge, power, and the subject to emerge in each of his major works. Flynn maps existentialist categories across Foucault's "quadrilateral," the model that Foucault proposes as defining modernist conceptions of knowledge. At stake is the degree to which Sartre's thought is fully captured by this mapping, whether he was, as Foucault claimed, "a man of the nineteenth century trying to think in the twentieth.". (shrink)

Social influence and social learning are important to the survival of many organisms, and certain forms of social learning also may have important implications for their underlying cognitive processes. The various forms of social influence and learning are discussed with special emphasis on the mechanisms that may be responsible for opaque imitation (the copying of a response that the observer cannot easily see when it produces the response). Three procedures are examined, the results of which may qualify as opaque imitation: (...) the bidirectional control procedure, the two- action procedure, and the do-as-I-do procedure. Variables that appear to affect the emergence of opaque imitation are identified and other complex forms of response copying are discussed. Keywords: bidirectional control procedure; contagion; emulation; imitation; local enhancement; object movement reenactment; observational conditioning; opaque imitation; social enhancement; social facilitation; social influence; social learning; stimulus enhancement; two action procedure.
