Michael Wheeler: Reconstructing The Cognitive World: The Next Step, Leslie Marsh

Leslie Marsh

Michael Wheeler is the latest in a new wave of philosophical theorists that fall within a loose coalition of anti-representationalism (or anti-Cartesianism): Dynamical –, Embodied –, Extended –, Distributed –, and Situated –, theories of cognition (DEEDS an apt acronym). Against this background, cognition for Wheeler is, or should be, a more ecumenical concept. This ecumenical approach would still be amenable to making theoretical distinctions, the central one being the notion of offline and online styles of intelligence, a distinction that makes conceptual space for another closely related notion, that of propositional knowledge (knowing that) and tacit knowledge (knowing how).


Application Of Microsatellite Dna Markers To Discriminate Maternal And Genetic Effects On Scalation And Behavior In Multiply-Sired Garter Snake Litters, Gordon Burghardt Jan 2007

Application Of Microsatellite Dna Markers To Discriminate Maternal And Genetic Effects On Scalation And Behavior In Multiply-Sired Garter Snake Litters, Gordon Burghardt

Gordon Burghardt

Incomplete knowledge of pedigrees sometimes limits the methods of estimating quantitative genetic parameters (heritability, genetic correlation) in nature and may result in estimates that are inflated by nongenetic sources of variation. North American garter snakes and their allies provide a model system for investigating evolutionary quantitative genetics, but estimates of quantitative genetic parameters in these snakes are mostly based on offspring-dam regression and full-sib analysis, methods that fail to discriminate between maternal genetic, maternal environmental, and direct genetic effects on traits of interest. Using data from the garter snake Thamnophis sirtalis, we demonstrate that microsatellite DNA markers can be used …
