Book excerpt: Auditory and visual speech recognition unfolds in real time and occurs effortlessly for normal hearing listeners. However, model theoretic descriptions of the systems level cognitive processes responsible for integrating auditory and visual speech information are currently lacking, primarily because they rely too heavily on accuracy rather than reaction time predictions. Speech and language researchers have argued about whether audiovisual integration occurs in a parallel or in coactive fashion, and also the extent to which audiovisual occurs in an efficient manner. The Double Factorial Paradigm introduced in Section 1 is an experimental paradigm that is equipped to address dynamical processing issues related to architecture (parallel vs. coactive processing) as well as efficiency (capacity). Experiment 1 employed a simple word discrimination task to assess both architecture and capacity in high accuracy settings. Experiments 2 and 3 assessed these same issues using auditory and visual distractors in Divided Attention and Focused Attention tasks respectively. Experiment 4 investigated audiovisual integration efficiency across different auditory signal-to-noise ratios. The results can be summarized as follows: Integration typically occurs in parallel with an efficient stopping rule, integration occurs automatically in both focused and divided attention versions of the task, and audiovisual integration is only efficient (in the time domain) when the clarity of the auditory signal is relatively poor--although considerable individual differences were observed. In Section 3, these results were captured within the milieu of parallel linear dynamic processing models with cross channel interactions. Finally, in Section 4, I discussed broader implications for this research, including applications for clinical research and neural-biological models of audiovisual convergence.

This book was released on 2014-07-09 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perceptual processes mediating recognition, including the recognition of objects and spoken words, is inherently multisensory. This is true in spite of the fact that sensory inputs are segregated in early stages of neuro-sensory encoding. In face-to-face communication, for example, auditory information is processed in the cochlea, encoded in auditory sensory nerve, and processed in lower cortical areas. Eventually, these “sounds” are processed in higher cortical pathways such as the auditory cortex where it is perceived as speech. Likewise, visual information obtained from observing a talker’s articulators is encoded in lower visual pathways. Subsequently, this information undergoes processing in the visual cortex prior to the extraction of articulatory gestures in higher cortical areas associated with speech and language. As language perception unfolds, information garnered from visual articulators interacts with language processing in multiple brain regions. This occurs via visual projections to auditory, language, and multisensory brain regions. The association of auditory and visual speech signals makes the speech signal a highly “configural” percept. An important direction for the field is thus to provide ways to measure the extent to which visual speech information influences auditory processing, and likewise, assess how the unisensory components of the signal combine to form a configural/integrated percept. Numerous behavioral measures such as accuracy (e.g., percent correct, susceptibility to the “McGurk Effect”) and reaction time (RT) have been employed to assess multisensory integration ability in speech perception. On the other hand, neural based measures such as fMRI, EEG and MEG have been employed to examine the locus and or time-course of integration. The purpose of this Research Topic is to find converging behavioral and neural based assessments of audiovisual integration in speech perception. A further aim is to investigate speech recognition ability in normal hearing, hearing-impaired, and aging populations. As such, the purpose is to obtain neural measures from EEG as well as fMRI that shed light on the neural bases of multisensory processes, while connecting them to model based measures of reaction time and accuracy in the behavioral domain. In doing so, we endeavor to gain a more thorough description of the neural bases and mechanisms underlying integration in higher order processes such as speech and language recognition.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1987. This book is about the processing of information. The central domain of interest is face-to-face communication in which the speaker makes available both audible and visible characteristics to the perceiver. Articulation by the speaker creates changes in atmospheric pressure for hearing and provides tongue, lip, jaw, and facial movements for seeing. These characteristics must be processed by the perceiver to recover the message conveyed by the speaker. The speaker and perceiver must share a language to make communication possible; some internal representation is necessarily functional for the perceiver to recover the message of the speaker. The current study integrates information-processing and psychophysical approaches in the analysis of speech perception by ear and eye.

This book was released on 2017-01-26 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present Research Topic explores closely related aspects of mental functioning, namely an interplay between perception and cognition, interactions among various sensory modalities, and finally, more or less unified conscious experiences arising in the context of these relations. Contributions emphasize a high flexibility observed in perception and may be seen as potential challenges to the traditional modular architecture of perceptual systems. Although the articles describe different phenomena, they follow one common theme - to investigate broadly understood unified experience - by studying either perception-cognition integration or the integration between sensory modalities. These integrative processes may well apply to subpersonal unconscious representations. However, the aim here is to approach phenomenal experience and thus a straightforward way of thinking about it is in terms of conscious perception. Putting together scientific and philosophical concerns, this special issue encourages extending the study of perceptual experience beyond the single sense perception to advance our understanding of the complex interdependencies between different sensory modalities, other mental domains, and various kinds of unifying relations within conscious experience. It exhibits a remarkable need to study these phenomena in tangent, and so, the authors examine a variety of ways in which our perceptual experiences may be cross-modal or multisensory, integrated, embodied, synesthetic, cognitively penetrated, or otherwise affected by top-down influences. The Research Topic comprises theoretical and empirical contributions of such fields as philosophy of mind, cognitive science, psychology, and neuroscience in the form of hypothesis and theory articles, original research articles, opinion papers, reviews, and commentaries.

This book was released on 2017-07-04 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of information from various sensory modalities influences behaviour. It can induce behavioural benefits such as faster reaction times and enhanced detection of noisy signals but may also produce illusions, all of which have been characterized by specific neuronal signatures. Yet, while these effects of multisensory integration are largely accepted, the role of attention in this process is still the object of intense debate. On the one hand, it has been suggested that attention may guide multisensory integration in a top-down fashion by selection of specific inputs to be integrated out of the plethora of information in our environment. On the other hand, there is evidence that integration could occur in a bottom-up manner, based on temporal and spatial correlations, and outside the focus of attention. An extreme example is the multisensory enhancement of neural responses in anesthetised animals. Attention itself is not a unitary construct, and may refer to a range of different selection mechanisms. Therefore, the interplay between attention and multisensory integration can take many forms which explain, in part, the diversity of findings and the disputes in the literature. The goal of this Research Topic is to help clarify the picture by trying to answer the following questions from various perspectives: Under which circumstances does multisensory integration take place without attention?, and, When does attention determine the fate of multisensory integration?

Book excerpt: This book is one outcome of the NATO Advanced Studies Institute (ASI) Workshop, "Speechreading by Man and Machine," held at the Chateau de Bonas, Castera-Verduzan (near Auch, France) from August 28 to Septem ber 8, 1995 - the first interdisciplinary meeting devoted the subject of speechreading ("lipreading"). The forty-five attendees from twelve countries covered the gamut of speechreading research, from brain scans of humans processing bi-modal stimuli, to psychophysical experiments and illusions, to statistics of comprehension by the normal and deaf communities, to models of human perception, to computer vision and learning algorithms and hardware for automated speechreading machines. The first week focussed on speechreading by humans, the second week by machines, a general organization that is preserved in this volume. After the in evitable difficulties in clarifying language and terminology across disciplines as diverse as human neurophysiology, audiology, psychology, electrical en gineering, mathematics, and computer science, the participants engaged in lively discussion and debate. We think it is fair to say that there was an atmosphere of excitement and optimism for a field that is both fascinating and potentially lucrative. Of the many general results that can be taken from the workshop, two of the key ones are these: • The ways in which humans employ visual image for speech recogni tion are manifold and complex, and depend upon the talker-perceiver pair, severity and age of onset of any hearing loss, whether the topic of conversation is known or unknown, the level of noise, and so forth.

Book excerpt: Cognitive neuroscience has grown into a rich and complex discipline, some 35 years after the term was coined. Given the great expanse of the field, an inclusive and authoritative resource such as this handbook is needed for examining the current state-of-the-science in cognitive neuroscience. Spread across two volumes, the 59 chapters included in this handbook systemically survey all aspects of cognitive neuroscience, spanning perception, attention, memory, language, emotion, self and social cognition, higher cognitive functions, and clinical applications. Additional chapters cover topics ranging from the use of top-down cognitive processes in visual perception to the representation and recognition of objects and spatial relations; attention and its relationship to action as well as visual motor control; language and related core abilities including semantics, speech perception and production, the distinction between linguistic competence and performance, and the capacity for written language. Special coverage is also given to chapters describing the psychopharmacology of cognition, the theory of mind, the neuroscience underlying the regulation of emotion, and neuropsychological and neuroimaging evidence that supports the special status of self-knowledge in memory. This handbook provides a comprehensive compendium of research on cognitive neuroscience that will be widely accessible to students, researchers, and professionals working in this exciting and growing field.
