Perceptual processes in humans and machines, investigatedand simulated by means of the computational approach, arethe subject matter of this volume. Researchers in artificialintelligence, pattern recognition, and psychology discussaspects of vision, speech understanding, sensory-motorcoordination, and their interplay with cognitive andbehavioral functionalities.The papers adopt the computational approach as the basicresearch paradigm. Connectionist models, numerical andstatistical techniques, symbolic (logic-based) formalisms,and hybrid representations provide the formal background tothe research. Some of the papers were prepared for aworkshop held in Trieste, Italy, in October 1992.
