s Friday Special Symposium: Beyond the Perception/Action Dissociation Dissociations and interactions of two visual processing-streams in sensori-motor control The dissociation of visual processing for sensori-motor control (the dorsal stream) and for conscious perception and cognitive processing (the ventral stream) has emerged as one of the important concepts in contemporary cognitive neuroscience. However, motor control processes are able to take into account information from memory and context-dependent representations normally attributed to the ventral stream. This symposium will explore issues related to the integration of these two streams for adaptive motor control. Bernhard Hommel, University of Leiden How we do what we want Voluntary actions are performed to achieve intended goals, suggesting that they are controlled through anticipating the effects they are expected to produce (the ideo-motor principle). According to the two-phase model of voluntary action proposed by Hommel and colleagues (Hommel, 1997; Elsner & Hommel, 2001) performing a movement leads to the automatic integration of its sensory effects and the motor pattern producing them. The resulting action concept, a truly sensorimotor structure, can then be used in the reverse direction: to activate the motor pattern by priming the effect representations. I present old and new evidence supporting this two-phase model from behavioral experiments in adults and infants, and from a PET study.

Bayesian models of child development.
Bayesian models have been applied to many areas of cognitive science including vision, language, and motor learning. We discuss the implications of this framework for cognitive development. We first present a brief introduction to the Bayesian framework. Bayesian models make assumptions about representation explicit, and provide a detailed account of learning. Furthermore, they can provide an a...
متن کاملExplanation-based Mechanisms for Learning: An Interdisciplinary Approach
The significant role of explanation in learning and generalization is ubiquitous and well documented: explanation promotes student learning in educational settings, drives conceptual development in young children, is accorded a central role in theories of conceptual representation, and has a long history in artificial intelligence. Despite this, relatively little is known about the precise mech...
متن کاملConcept Mapping in Science Education Assessment: an Approach to Computer-supported Achievement Tests in an Interdisciplinary Hypermedia Learning Environment
The acquisition of conceptual knowledge is a central aim in science education. In this study, an interdisciplinary hypermedia-media assisted learning unit about hibernation and thermodynamics was developed and evaluated. But the assessment of interdisciplinary knowledge is not trivial. Therefore, concept mapping procedures were used to assess the cognitive effects within this complex knowledge ...
متن کاملSocial learning and traditions in animals: evidence, definitions, and relationship to human culture.
The number of publications concerned with social learning in nonhuman animals has expanded dramatically in recent decades. In this article, recent literature addressing three issues that have been of particular concern to those with both an interest in social learning and a background in experimental psychology are reviewed: (1) the definition as well as (2) empirical investigation of the numer...
متن کاملA Web site in cognitive science.
A Web site (http://web2-pc.uncc.edu/cogsci) has been established to support an interdisciplinary course in cognitive science. The modules include introductory reading material, interactive exercises/virtual laboratory, and pointers to existing material on the Web. Our approach to using the Web in support of instruction differs from distance learning initiatives because it is centered on an inst...
