Book Description
Scientists and practitioners alike have long been interested in the nature of linguistic breakdown in individuals with aphasia. Throughout history, the predominant approach to classifying features of this disorder has been one of discrete categorization in a number of domains of processing. There has been an abundance of empirical evidence, however, to support claims that behaviors are more adequately viewed as continuous, and that processing in one domain is correlated to processing in other domains within the linguistic structure. Nonetheless, we continue to discuss functions as being impaired or remaining intact after injury, as if these were discrete states. Moreover, we look for these patterns both within and across domains as a way to try to distinguish one group of aphasic individuals from another. The purpose of this study was to investigate the nature of lexical comprehension in individuals with aphasia. In particular, this work challenges claims that lexical function remains intact in certain populations of aphasics by examining lexical processing under degraded conditions. Two different types of exogenous stressors (low-pass filtering and time compression), and a combination of both were used in order to explore the differential impact on processing in the linguistic domain. These stressors, which are common conditions experienced in real world processing, and have also been claimed to mimic conditions often present in aging adults (hearing loss and cognitive slowing) are particularly interesting to explore in aphasic populations to get a better sense of what processing looks like under typical conditions. Additionally, this work aimed to explore the relationship between lexical and sentential processing in order to better understand the nature of breakdown across linguistic levels. The goal here was to investigate whether or not deficits are present in one domain with a sparing of functions in another. Results suggest that all aphasic individuals, irrespective of classification type, are vulnerable to breakdowns in lexical comprehension as compared to older adults when they are processing in less-than-optimal conditions. Furthermore, there was no evidence for a dissociation between levels of the linguistic system as performance at the lexical level was predictive of performance at the sentence level.

Book Description
Aphasia Rehabilitation: Challenging Clinical Issues focuses on specific aphasia symptoms and clinical issues that present challenges for rehabilitation professionals. These topics are typically not addressed as separate topics, even in clinical texts. This heavily clinical text will also include thorough discussions of theoretical underpinnings. For chapters that focus on specific clinical challenges, practical suggestions to facilitate clinical application and maximize clinical usefulness. This resource integrates theoretical and practical information to aid a clinician in planning treatment for individuals with aphasia.

Book Description
Linguistics and Aphasia is a major study of recent developments in applying psycholinguistics and pragmatics to the study of acquired language disorders (aphasia) and their remediation. Psycholinguistic analyses of aphasia interpret disorders in terms of damaged modules and processes within what was once a normal language system. These analyses have progressed to the point that they now routinely provide a model-based rationalefor planning patient therapy. Through a series of case studies, the authors show how the psycholinguistic analysis of aphasia can be assessed for its effectiveness in clinical practice. Pragmatic approaches to the study of aphasia are of more recent origin. Ruth Lesser and Lesley Milroy evaluate their considerable significance to the study of aphasia and their relevance to practical issues of diagnosis and treatment. Controversial analysis, in particular, offers a fruitful and productive framework within which to assess the functional adequacy of the language used by aphasic speakers in everyday contexts.

Book Description
Speech is multisensory since it is perceived through several senses. Audition is the most important one as speech is mostly heard. The role of vision has long been acknowledged since many articulatory gestures can be seen on the talker's face. Sometimes speech can even be felt by touching the face. The best-known multisensory illusion is the McGurk effect, where incongruent visual articulation changes the auditory percept. The interest in the McGurk effect arises from a major general question in multisensory research: How is information from different senses combined? Despite decades of research, a conclusive explanation for the illusion remains elusive. This is a good demonstration of the challenges in the study of multisensory integration. Speech is special in many ways. It is the main means of human communication, and a manifestation of a unique language system. It is a signal with which all humans have a lot of experience. We are exposed to it from birth, and learn it through development in face-to-face contact with others. It is a signal that we can both perceive and produce. The role of the motor system in speech perception has been debated for a long time. Despite very active current research, it is still unclear to which extent, and in which role, the motor system is involved in speech perception. Recent evidence shows that brain areas involved in speech production are activated during listening to speech and watching a talker's articulatory gestures. Speaking involves coordination of articulatory movements and monitoring their auditory and somatosensory consequences. How do auditory, visual, somatosensory, and motor brain areas interact during speech perception? How do these sensorimotor interactions contribute to speech perception? It is surprising that despite a vast amount of research, the secrets of speech perception have not yet been solved. The multisensory and sensorimotor approaches provide new opportunities in solving them. Contributions to the research topic are encouraged for a wide spectrum of research on speech perception in multisensory and sensorimotor contexts, including novel experimental findings ranging from psychophysics to brain imaging, theories and models, reviews and opinions.

Book Description
This book is a comprehensive overview of the main current concepts in brain cognitive activities at the global, collective (or network) level, with a focus on transitions between normal neurophysiology and brain pathological states. It provides a unique approach of linking molecular and cellular aspects of normal and pathological brain functioning with their corresponding network, collective and dynamical manifestations that are subsequently extended to behavioural manifestations of healthy and diseased brains. This book introduces a high-level perspective, searching for simplification amongst the structural and functional complexity of nervous systems by consideration of the distributed interactions that underlie the collective behaviour of the system. The authors hope that this approach could promote a global comprehensive understanding of high-level laws behind the elementary biological processes in the neuroscientific community, while, perhaps, introducing elements of biological complexities to the mathematical/computational readership. The title of the book refers to the main point of the monograph: that there is a smooth continuum between distinct brain activities resulting in different behaviours, and that, due to the plastic nature of the brain, the behaviour can also alter the brain function, thus rendering artificial the boundaries between the brain and its behaviour.
