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 such as the Gibsons. They find it extremely artificial to regard natural information as being cut up and requiring cementing. Nevertheless, the possibility that during ontogene sis, perception involves the integration of separate information has attracted the attention of scholars concerned with both normal and abnormal development. In the case of normal development, a lively controversy has arisen between those who believe perceptual develop ment goes from integration toward differentiation and those who hold the opposite view. In the case of abnormal psychological development such as learning disabilities, many workers have suggested that percep tual integration is at fault. In thinking about the issues raised in this volume, we are particularly indebted to our former teachers and colleagues: Eleanor and James Gibson, T. A. Ryan, Robert B. MacLeod, and Jerome Bruner. We are pleased to acknowledge the secretarial help of Karen Weeks in the preparation of this volume.

This book provides the latest information about the development of intersensory perception -- a topic which has recently begun to receive a great deal of attention from researchers studying the general problem of perceptual development. This interest was inspired after the realization that unimodal perception of sensory information is only the first stage of perceptual processing. Under normal conditions, an organism is faced with multiple, multisensory sources of information and its task is to either select a single relevant source of information or select several sources of information and integrate them. In general, perception and action on the basis of multiple sources of information is more efficient and effective. Before greater efficiency and effectiveness can be achieved, however, the organism must be able to integrate the multiple sources of information. By doing so, the organism can then achieve a coherent and unified percept of the world. The various chapters in this book examine the developmental origins of intersensory perceptual capacities by presenting the latest research on the development of intersensory perceptual skills in a variety of different species. By adopting a comparative approach to this problem, this volume as a whole helps uncover similarities as well as differences in the mechanisms underlying the development of intersensory integration. In addition, it shows that there is no longer any doubt that intersensory interactions occur right from the beginning of the developmental process, that the nature of these intersensory interactions changes as development progresses, and that early experience contributes in important ways to these changes.

The present study investigated the intersensory processing deficit for social stimuli in individuals with ASD compared to age- and cognitive-ability matched typically developing peers. This deficit was theorized to account (at least partially) for cascading impairments in attention and autism symptomatology across development. The primary goal was to isolate the social and linguistic properties of intersensory (audio-visual) processing using a manipulation of temporal synchrony. In Study One, a multi-method analysis of looking time and proportion of efficient gaze patterns using eye-tracking data from a behavioural task was used. Results provided evidence of a difference in intersensory processing specifically for social stimuli in children with ASD that does not appear to be solely attributable to a deficit in processing faces, language, or body movement. The secondary goal of the project was to provide a better understanding of variables that impact and are impacted by intersensory processing. In Study Two the strength and direction of the relationship between intersensory processing and developmental, diagnostic, and attention variables was assessed. Results showed that impaired intersensory processing for social information appears to be associated with cascading consequences across development including some of the core impairments in Autism Spectrum Disorder: disrupted sensory processing, social-communication disability, and slower attentional disengagement. In summary, results of Study One and Study Two are best understood as a specific cognitive-perceptual deficit in social orienting and are consistent with the Intersensory Redundency Hypothesis. The observed intersensory processing differences between groups may be impacted by dysfunctional intersensory integration wherein the most general amodal property, temporal synchrony, is misprocessed at early stages, disrupting selective attention and early social orienting. This impairment impacts the cascading cycle of perception, learning, memory, attention and so on and contributes to core sensory and social-communication impairments associated with Autism Spectrum Disorder.

We perceive and understand our environment using many sensory systems-vision, touch, hearing, taste, smell, and proprioception. These multiple sensory modalities give us complementary sources of information about the environment. This book explores how we develop the ability to integrate our senses.

It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

Research is suggesting that rather than our senses being independent, perception is fundamentally a multisensory experience. This handbook reviews the evidence and explores the theory of broad underlying principles that govern sensory interactions, regardless of the specific senses involved.

In Intersensory Origin of Mind Thorne Shipley proposes a fundamental revision of the core of modern psychology. With a serious respect for the history of science, Shipley shows the profound limits of linear, mechanistic and naively reductionistic accounts of the mind, and proposes instead a sensory rationalist position which builds on the principles of emergent evolution. Combining several diverse perspectives, from the physiological optics of Helmholtz, the perceptual science of Kohler, the visual electrophysiology of Hubel/Wiesel to the theories of Dewey, Polanyi, Cassirer, Chomsky and Piaget, Intersensory Origin of Mind is an ambitious synthesis of sensory science. It will need to be read by anyone with an interest in philosophical psychology, the nature of human consciousness and the origin of mind.

Simple reaction time to stimuli from different sensory modalities presented simultaneously typically is shorter than reaction time to a single stimulus. In this study, auditory, visual, and tactile stimuli were presented in different combinations and at varying stimulus onset asynchronies. Two different types of models for the observed reaction time facilitation effects are developed and tested. Separate activation (race) type models assume that stimulus information in different sensory channels is processed in parallel and independently while coactivation type models allow interactions across different channels. Using Boole's inequality as a test for separate activation models it could be shown that these models cannot predict as much facilitation as observed. A superposition and a diffusion model of coactivation provided a promising quantitative approximation to the data.
