  • A Philosophical Investigation of Principlism and the Implications Raised by the Treatment of the Mentally Ill

    A Philosophical Investigation of Principlism and the Implications Raised by the Treatment of the Mentally Ill

    Aporia vol. 24 no. 1—2014 A Philosophical Investigation of Principlism and the Implications Raised by the Treatment of the Mentally Ill BENJAMIN FOSTER Introduction he objective of this investigation is to identify reasonable and relevant problems and issues posed for Principlism by the mentally T ill. Two concepts of Principlism will be presented: a normative con- ceptualization of the bioethical theory and a descriptive conceptualization. In reference to both, two philosophical questions will be asked: can we know the natures of other minds and, if so, how? These two questions have theoretical and practical implications for the treatment of the mentally ill. And, in so far as the questions have implications for the treatment of the mentally ill, they have implications for the bioethical theory of Principlism. There is a lack of concurrence on the meaning, nature, and function of mental phenomena, producing conceptual difficulties concerning the common morality that provides Principlism its normative authority. Similarly, a contradiction appears to arise when one considers the imaginative leap of predicting another’s desires, feelings, and thoughts, a maneuver that professionals participating in the treatment of the mentally ill must perform. There is also significant ambiguity surrounding the concept of mental illness, which produces pragmatic problems when professionals attempt to diagnose and treat an individual in conjunction Benjamin Foster graduated with a degree in philosophy and a minor in biology from the University of Alaska Fairbanks. While there he served as president of the univer- sity’s philosophy club, The Socratic Society. His primary philosophical interests include ethics and epistemology. He currently plans to attend medical school.

    Literature and the Cognitive Revolution: an Introduction

    Literature and the Cognitive Revolution: An Introduction Alan Richardson English, Boston College Francis F. Steen Communication Studies, UCLA Literary studies and the cognitive sciences, pursuing common interests in language, mental acts, and linguistic artifacts, have developed markedly different approaches to similar phenomena of reading, imaginative involve- ment, and textual patterning. Until quite recently, the distance between them has drawn more attention than their possible convergence (Franchi and Güzeldere ). A number of literary theorists and critics, however, have steadily been producing work that finds its inspiration, its method- ology, and its guiding paradigms through a dialogue with one or more fields within cognitive science: artificial intelligence, cognitive psychology, post- Chomskian linguistics, philosophy of mind, neuroscience, and evolution- ary biology. Reuven Tsur () has been developing his ‘‘cognitive poet- ics’’ since the s; the prominent psychoanalytic critic Norman Holland (: ) demonstrated the advantages of attending to the ‘‘more powerful psychology’’ emerging from cognitive neuroscience in ; Mark Turner (: viii) advanced his far-reaching project of a ‘‘cognitive rhetoric’’ in ; and Ellen Spolsky (: ) trenchantly brought a theory of ‘‘cogni- tive instability’’ to bear on literary interpretation in . These and like- minded critics respond to the limitations (or, in Spolsky’s case, missed op- portunities) of poststructuralist conceptions of meaning and interpretation by questioning the reigning models in the field, whether in the interest of Poetics Today : (Spring ).

Barriers to Creativity in Engineering Education: A Study of Instructors and Students Kazem Kazerounian Professor Fellow ASME Perceptions Stephany Foley This paper studies “creativity” in engineering education, by examining the perception of NSF Graduate Fellow instructors and students. We aim to identify factors that impede a creative environment (creativity blockers). The study entails a review of established research in the fields of Department of Mechanical Engineering, psychology and educational psychology to identify factors which create an educational University of Connecticut, environment conducive to creativity. These factors are formalized in the Ten Maxims of Storrs, CT 06269-3139 Creativity in Education, a set of criteria that constitute an educational environment conducive to fostering creativity in students. These maxims form the basis for our work in examining the contemporary engineering education. Extensive surveys are designed, cre- ated, distributed, and statistically quantified to study the perceptions of engineering edu- cators and students, in comparison to nonengineering educators and students.

    The 11th International Conference on Education Research New Educational Paradigm for Learning and Instruction September 29 – October 1, 2010 Cognitive and Neuroscience Research on Learning and Instruction: Recent insights about the impact of non-conscious knowledge on problem solving, higher order thinking skills 12 and interactive cyber-learning environments. Richard E. Clark University of Southern California, USA Abstract There are as least three powerful insights from recent studies of the brain that support cognitive science research findings: First, our brains learn and process two very different types of knowledge; non conscious, automated knowledge and conscious, controllable, declarative knowledge. Evidence also suggests that we believe we control our own learning by conscious choice when in fact nearly all mental operations are highly automated, including learning and problem solving; Second, human beings have a very limited capacity to think during learning and problem solving and when that capacity is exceeded, thinking and learning stop without us being aware. Thus instruction and self managed learning must strive to avoid cognitive overload; and Third, nearly all of our instructional design and cyber learning theories and models fail to account for the influence of non-conscious cognitive processes and therefore are inadequate to deal with complex learning and performance. Evidence for these points will be described and their implications for instruction and the learning of problem solving and higher order thinking skills will be discussed. Models of learning and instruction that appear to help overcome some of these biological and cognitive barriers will be described. In addition, suggestions for new research questions on interactive learning environments that take account of the three insights will also be described.

ISSN: 1756-8757 print / 1756-8765 online DOI: 10.1111/j.1756-8765.2012.01199.x Anthropology’s Disenchantment With the Cognitive Revolution1 Richard A. Shweder Department of Comparative Human Development, University of Chicago Received 25 June 2011; received in revised form 3 November 2011; accepted 28 November 2011 Abstract Beller, Bender, and Medin should be congratulated for their generous attempt at expressive aca- demic therapy for troubled interdisciplinary relationships. In this essay, I suggest that a negative answer to the central question (‘‘Should anthropology be part of cognitive science?’’) is not necessar- ily distressing, that in retrospect the breakup seems fairly predictable, and that disenchantment with the cognitive revolution is nothing new. Keywords: Cognitive revolution; Behaviorism; Anthropology; Jerome Bruner; Roy D’Andrade; Clifford Geertz; Roger Shepard Some of the leaders of the cognitive revolution of the late 1950s and 1960s began parting from the cause almost as soon as it triumphed. Jerome Bruner, for example, who always enjoyed writing essays for both the left hand and the right hand, turned to hermeneutics, the study of law, and the interpretation of narratives (see Bruner, 1979, 1990). Even in the early days of the rebellion Bruner was attentive to language pragmatics, which may be one reason he named his 1960s big tent interdisciplinary center at Harvard University the ‘‘Center for Cognitive Studies’’ and not the ‘‘Center for Cognitive Science.’’ Bruner had just as much interest in the humanistic writings of E. H. Gombrich, Nelson Goodman, and Clifford Ge- ertz as in the latest claims about basic ⁄fundamental⁄universal cognitive processes coming out of experimental labs situated in Cambridge, London, or Geneva.

    The Place of Modeling in Cognitive Science

    The place of modeling in cognitive science James L. McClelland Department of Psychology and Center for Mind, Brain, and Computation Stanford University James L. McClelland Department of Psychology Stanford University Stanford, CA 94305 650-736-4278 (v) / 650-725-5699 (f) [email protected] Running Head: Modeling in cognitive science Keywords: Modeling frameworks, computer simulation, connectionist models, Bayesian approaches, dynamical systems, symbolic models of cognition, hybrid models, cognitive architectures Abstract I consider the role of cognitive modeling in cognitive science. Modeling, and the computers that enable it, are central to the field, but the role of modeling is often misunderstood. Models are not intended to capture fully the processes they attempt to elucidate. Rather, they are explorations of ideas about the nature of cognitive processes. As explorations, simplification is essential – it is only through simplification that we can fully understand the implications of the ideas. This is not to say that simplification has no downsides; it does, and these are discussed. I then consider several contemporary frameworks for cognitive modeling, stressing the idea that each framework is useful in its own particular ways. Increases in computer power (by a factor of about 4 million) since 1958 have enabled new modeling paradigms to emerge, but these also depend on new ways of thinking. Will new paradigms emerge again with the next 1,000-fold increase? 1. Introduction With the inauguration of a new journal for cognitive science, thirty years after the first meeting of the Cognitive Science Society, it seems essential to consider the role of computational modeling in our discipline.
