This volume on intersensory perception and sensory integration is the second volume of the series, Perception and Perceptual Development: A Critical Review Series. The topic of the volume is timely, for in recent years, many investigators have noted that information about any natural event is obtained by a perceiver from a variety of sources. Such an observation immediately leads to the question of how this information is synthesized and organized. Of course, the implication that there are several discrete input channels that must be processed has come under immediate attack by researchers...

In recent years, significant, indeed dramatic, advances have occurred in the study of perception. These have been made possible by, and, in fact, in- clude methodological advances such as the development of signal detection theory and the application of linear systems analysis to auditory and visual per- ception. They are reflected in an interest in the study of ecologically valid perceptual problems, e. g., control of locomotion, speech perception, reading, perceptual-motor coordination, and perception of events. At the same time, exciting new insights have been gained to some of the...
