This groundbreaking monograph offers a mechanistic theory of the representation and use of semantic knowledge, integrating the strengths and overcoming many of the weaknesses of hierarchical, categorization-based approaches, similarity-based approaches, and the approach often called "theory theory." Building on earlier models by Geoffrey Hinton in the 1980s and David Rumelhart in the early 1990s, the authors propose that performance in semantic tasks arises through the propagation of graded signals in a system of interconnected processing units. The representations used in performing these...

What makes people smarter than computers? These volumes by a pioneering neurocomputing group suggest that the answer lies in the massively parallel architecture of the human mind. They describe a new theory of cognition called connectionism that is challenging the idea of symbolic computation that has traditionally been at the center of debate in theoretical discussions about the mind.

The authors' theory assumes the mind is composed of a great number of elementary units connected in a neural network. Mental processes are interactions between these units which excite and inhibit...

Present educational finance policies can be construed to be in violation of the equal Protection Clause of the United states Constitution's Fourteenth Amendment. Assisted by the National Urban Coalition, the authors of this book have compiled a great deal of information and analysis on school services in the state of Michigan--information which may typify such services throughout the country. Their research was conducted initially to serve as evidence in a suit filed by the Detroit Board of Education which alleged dscrimination in the state's distribution of resources to schools: "It may...
