We use the Newell Test as a basis for evaluating ACT-R as an effective architecture for cognitive engineering. Of the 12 functional criteria discussed by Anderson & Lebiere (A&L), we discuss the strengths and weaknesses of ACT-R on the six that we postulate are the most relevant to cognitive engineering.
Cognition in work teams has been predominantly understood and explained in terms of shared cognition with a focus on the similarity of static knowledge structures across individual team members. Inspired by the current zeitgeist in cognitive science, as well as by empirical data and pragmatic concerns, we offer an alternative theory of team cognition. Interactive Team Cognition (ITC) theory posits that (1) team cognition is an activity, not a property or a product; (2) team cognition should be measured and studied (...) at the team level; and (3) team cognition is inextricably tied to context. There are implications of ITC for theory building, modeling, measurement, and applications that make teams more effective performers. (shrink)
This essay defends the view of G. C. Pande that, contrary to received opinion, "ānanda" (bliss, felicity) is accepted by Śaṅkara (ca. 788-820) as a feature of Brahman consistent with and parallel to sat (being) and cit (consciousness). It also includes a counterargument by B. N. K. Sharma, and in conclusion offers a reasoned judgment of the arguments of Śaṅkara and these two contemporary philosophers.
Wolfhart Pannenberg's eschatological ontology has been criticised for undermining the goodness and reality of finite creaturely differentiation. Drawing on David Bentley Hart's recent ontological proposal, this article explores the critique of Pannenberg's ontology, and offers a defence of Pannenberg's depiction of the relationship between difference and totality, especially as it is presented in his 1988 work, Metaphysics and the Idea of God. In this work, Pannenberg articulates a structured relationship between difference and totality in which individual finite particularities are preserved (...) and affirmed within a coherent semantic whole. Creaturely differences are not sublated or eliminated in the eschatological totality, but they are integrated into a harmonious totality of meaning. This view of the semantic function of totality can be further clarified by drawing an analogy between Pannenberg's ontological vision and Robert W. Jenson's model of the eschatological consummation as a narrative conclusion to the drama of finite reality. (shrink)
This is a review of a book that tries to re-establish mind-body dualism by using (a) empirical research on near-death experiences, placebo effects, creativity, claiming even that parapsychology should become a respected part of science, and (b) Frederic W. H. Myers' (1843-1901) metaphor of the brain as a kind of receiving device that records what the irreducible mind sends as messages. Among other things, we criticize the lack of philosophical clarity about mind-body relation, and question the book's tendency to (...) refer to past and current parapsychological literature as reliable.
