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 each other in parallel rather than sequential operations. In this context, knowledge can no longer be thought of as stored in localized structures; instead, it consists of the connections between pairs of units that are distributed throughout the network. Volume 1 lays the foundations of this exciting theory of parallel distributed processing, while Volume 2 applies it to a number of specific issues in cognitive science and neuroscience, with chapters describing models of aspects of perception, memory, language, and thought.

The contributions to this volume, the sixteenth in the prestigious Attention and Performance series, revisit the issue of modularity, the idea that many functions are independently realized in specialized, autonomous modules. Although there is much evidence of modularity in the brain, there is also reason to believe that the outcome of processing, across domains, depends on the synthesis of a wide range of constraining influences. The twenty-four chapters in Attention and Performance XVI look at how these influences are integrated in perception, attention, language comprehension, and motor control. They consider the mechanisms of information integration in the brain; examine the status of the modularity hypothesis in light of efforts to understand how information integration can be successfully achieved; and discuss information integration from the viewpoints of psychophysics, physiology, and computational theory.
