Semantic Cognition: A Parallel Distributed Processing Approach

摘要: This groundbreaking monograph offers a mechanistic theory of the representation and use semantic knowledge, integrating strengths overcoming many weaknesses hierarchical, categorization-based approaches, similarity-based approach often called "theory theory." Building on earlier models by Geoffrey Hinton in 1980s David Rumelhart early 1990s, authors propose that performance tasks arises through propagation graded signals system interconnected processing units. The representations used performing these are patterns activation across units, governed weighted connections among them. Semantic knowledge is acquired gradual adjustment course day-to-day experience. show how simple computational model proposed exhibits progressive differentiation conceptual paralleling aspects cognitive development seen work Frank Keil Jean Mandler. extend to address acquisition infancy, disintegration dementia, "basic-level" effects their interaction with expertise, findings introduced support idea cognition guided naive, domain-specific theories.
