The Impact of Herbert A. Simon

Here, several leading experts in the area of cognitive science summarize their current research programs, tracing Herbert A. Simon »s influence on their own work — and on the field of information processing at large. Topics covered include problem- solving, imagery, reading, writing, memory, expertise, instruction, and learning. Collectively, the chapters reveal a high degree of coherence across the various specialized disciplines within cognition — a coherence largely attributable to the initial unity in Simon »s seminal and pioneering contributions.
