Abstract

This collection of new essays on sensory individuals in unimodal and multimodal perception features contributions by outstanding researchers in the fields of philosophy of perception, experimental psychology, and cognitive neuroscience. The topics investigated include conceptual, developmental, and methodological aspects of object perception, and especially how various sense modalities construct their objects from sensory features and feature bearers. The interdisciplinary approach offered has enabled new directions in research on this subject. As ordered in this volume, the topics of the contributions progress from treating neural sensory processes as primarily unisensory towards approaches that take perceptual processing to be modality-independent, meta-modal, and multimodal. Even within these latter approaches, sensory stimuli, sensory properties, brain activations, and corresponding perceptual phenomenology have often been characterized in a modality-specific way. Thus, it is timely to explore the relation between those processes that are unisensory and those that are multisensory. One of the primary themes of this collection is examining whether the basic building blocks of human perception are best understood as modality-dependent units of different forms or in terms of multimodal perceptual objects. Another theme is the relation between low-level object processing (segmentation and perceptual grouping processes) and high-level object knowledge embracing object concept and object-related expectations. A final theme is the role that perceptual objects play as loci of unification in unimodal and multimodal perception, namely that they enable binding and integration of sensory properties to individual entities or events.
