This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Auditory localization, the ability to locate sounds, declines with age due to changes in peripheral and central auditory processing. As selective attention is typically preserved in older adults, drawing their attention towards the stimulus before it occurs may improve auditory localization. This study evaluated this hypothesis by precueing younger and older participants towards a likely location of the upcoming target (a broadband noise) with a visual attentional cue. The attentional cues either provided a) correct information about the upcoming target location (valid) b) incorrect information about the upcoming target location (invalid), or c) no information about the upcoming target location (neutral). Participants estimated the targetâ s location on a schematic drawing of the testing environment. Akin to younger adults, older adults made less errors and biases, and faster responses with valid cues. This suggests that older adults can employ selective attention to improve auditory localization, similar to younger adults.

Download or read book The Neural Bases of Multisensory Processes written by Micah M. Murray and published by CRC Press. This book was released on 2011-08-25 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Handbook of Attention written by Jonathan Fawcett and published by MIT Press. This book was released on 2015-11-27 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: An authoritative overview of current research on human attention, emphasizing the relation between cognitive phenomena observed in the laboratory and in the real world. Laboratory research on human attention has often been conducted under conditions that bear little resemblance to the complexity of our everyday lives. Although this research has yielded interesting discoveries, few scholars have truly connected these findings to natural experiences. This book bridges the gap between “laboratory and life” by bringing together cutting-edge research using traditional methodologies with research that focuses on attention in everyday contexts. It offers definitive reviews by both established and rising research stars on foundational topics such as visual attention and cognitive control, underrepresented domains such as auditory and temporal attention, and emerging areas of investigation such as mind wandering and embodied attention. The contributors discuss a range of approaches and methodologies, including psychophysics, mental chronometry, stationary and mobile eye-tracking, and electrophysiological and functional brain imaging. Chapters on everyday attention consider such diverse activities as driving, shopping, reading, multitasking, and playing videogames. All chapters present their topics in the same overall format: historical context, current research, the possible integration of laboratory and real-world approaches, future directions, and key and outstanding issues.

Available in PDF, EPUB and Kindle. Book excerpt: Speech perception has been the focus of innumerable studies over the past decades. While our abilities to recognize individuals by their voice state plays a central role in our everyday social interactions, limited scientific attention has been devoted to the perceptual and cerebral mechanisms underlying nonverbal information processing in voices. The Oxford Handbook of Voice Perception takes a comprehensive look at this emerging field and presents a selection of current research in voice perception. The forty chapters summarise the most exciting research from across several disciplines covering acoustical, clinical, evolutionary, cognitive, and computational perspectives. In particular, this handbook offers an invaluable window into the development and evolution of the 'vocal brain', and considers in detail the voice processing abilities of non-human animals or human infants. By providing a full and unique perspective on the recent developments in this burgeoning area of study, this text is an important and interdisciplinary resource for students, researchers, and scientific journalists interested in voice perception.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of the present thesis is to examine the cognitive control mechanisms underlying auditory selective attention by considering the influence of variables that increase the complexity of an auditory scene. Therefore, technical aspects such as dynamic binaural hearing, room acoustics and head movements as well as those that influence the efficiency of cognitive processing are taken into account. Step-by-step the well-established dichotic-listening paradigm is extended into a realistic spatial listening paradigm. Conducted empirical surveys are based on a paradigm examining the intentional switching of auditory selective attention. Performance measure differences between the repetition of the target's spatial position and the related switch describe the loss of efficiency associated with redirecting attention from one target's location to another. To examine whether the irrelevant auditory information is decoded, interference in the processing of task-relevant and task-irrelevant information is created in the paradigm. Using the binaural-listening paradigm, the ability to intentionally switch auditory selective attention is tested when applying different methods of spatial reproduction. Essential differences between real sources, an individual and a non-individual binaural synthesis are found. As a step towards multi-talker scenarios in realistic environments participants are tested in differently reverberating environments, resulting in highly affected switch costs. Age-related effects are found when applying the binaural-listening paradigm, indicating difficulties for elderly to suppress processing the distractor's speech.

Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, there have been enormous advances in our understanding of the neural mechanisms of selective attention at the network as well as the cellular level. The Oxford Handbook of Attention brings together the different research areas that constitute contemporary attention research into one comprehensive and authoritative volume. In 40 chapters, it covers the most important aspects of attention research from the areas of cognitive psychology, neuropsychology, human and animal neuroscience, computational modelling, and philosophy. The book is divided into 4 main sections. Following an introduction from Michael Posner, the books starts by looking at theoretical models of attention. The next two sections are dedicated to spatial attention and non-spatial attention respectively. Within section 4, the authors consider the interactions between attention and other psychological domains. The last two sections focus on attention-related disorders, and finally, on computational models of attention. Aimed at both scholars and students, the Oxford Handbook of Attention provides a concise and state-of-the-art review of the current literature in this field.

Download or read book Time Will Tell written by Mari Riess Jones and published by Oxford University Press, USA. This book was released on 2019 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention is a central concept in psychology. The term 'attention' itself has persisted, even though it implies a static, insulated capacity that we use when it is necessary to focus upon some relevant or stimulating event. Riess Jones presents a different way of thinking about attention; one that describes it as a continuous activity that is based on energy fluctuating in time. A majority of attention research fails to examine influence of event time structure (i.e., a speech utterance) on listeners' moment-to-moment attending. General research ignores listeners endowed with innate, as well as acquired, temporal biases. Here, attending is portrayed as a dynamic interaction of an individual within his or her surroundings. Importantly, this interaction involves synchronicity between an attender and external events. This emphasis on time and synchronicity distinguishes the author's theory, called Dynamic Attending Theory (DAT), from other approaches to attending which characterize attention metaphorically as a filter, resource pool, spotlight, and so on. Recent research from neuroscience has lent support to Riess Jones' theory, and the goal of this book is to bring this new research as well as her own to the wide audience of psychologists interested in attention more broadly.

Available in PDF, EPUB and Kindle. Book excerpt: Purpose: This study was designed to investigate (1) the effects of age and hearing loss on auditory neural coding, (2) interrelationships between auditory evoked potentials (AEP) taking place at early and later stage of auditory processing, and (3) electrophysiological correlates of age-related declines in speech-in-noise perception. Methods: 30 young normal-hearing adults (YNH, M=21 years), 26 older adults with near-normal hearing (ONH, M=63.9 years) and 26 older adults with hearing loss (OHL, M=72.8 years) participated in the study. AMLR Pa and N1, P2 and N2 of ALLRs were recorded using two-channel electrode system. 500 Hz tone burst and syllable /ba/ were presented in quiet and in babble at the level of 90 Leq (dBA), accompanied by babble at the level of 65 Leq (dBA). Revised Speech Perception in Noise (R-SPIN) test was conducted to measure speech-in-noise perception. Results: ONH listeners demonstrated significantly enhanced Pa and N1 amplitudes and significantly prolonged Pa, P2 and N2 latencies compared with YNH listeners, indicating the effects of aging. OHI group demonstrated significantly prolonged N2 latencies compared with ONH group, indicating the effects of hearing loss. OHI listeners demonstrated significantly enhanced amplitudes and significantly prolonged latencies across all AEP components compared with YNH listeners, indicating that the combined effects may have stronger impacts on age-related changes in AEP morphology. Significant correlations between the amplitudes of Pa and each component of ALLRs were found in ONH and OHI groups, indicating that enhanced Pa amplitudes correspond with enhanced amplitudes of cortical responses in older listeners. Significant correlations between latencies of Pa and each component of ALLRs were found in all groups, indicating that prolonged Pa latencies correspond with prolonged latencies of cortical responses in all listeners. In both ONH and OHI groups, lower R-SPIN-LP scores are significantly correlated with enhanced Pa, P2, and N2 amplitudes and prolonged N2 latencies, particularly for syllable /ba/. Discussion and Conclusions: Interplay between effects of aging and hearing loss may have stronger impacts on morphological changes in the AEP waveforms. Amplitude-based interrelationships reflect age-related changes in a transfer of neural information between subcortical and cortical auditory network. Latency-based interrelationships indicate the association between neural timings at subcortical and cortical levels. Age-related enhancements of Pa, P2 and N2 amplitudes and age-related prolongations of N2 latencies may serve as electrophysiological correlates of age-related declines in SIN perception.

Download or read book Binaural Interference a Guide for Audiologists written by James Jerger and published by Plural Publishing. This book was released on 2018-02-23 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binaural interference occurs when the speech input to one ear interferes with the input to the other ear during binaural stimulation. The first published study on binaural interference twenty-five years ago demonstrated that some individuals, particularly older individuals, perform more poorly with two hearing aids than with one and/or more poorly with binaural than monaural stimulation on electrophysiologic as well as behavioral measures. Binaural interference is relevant to every audiologist because it impacts the successful use of binaural hearing aids and may explain communicative difficulty in noise or other challenging listening situations in persons with normal-hearing sensitivity as well as persons with hearing loss. This exciting new book written by two highly respected audiologists first traces the history of its study by researchers, then reviews the evidence, both direct and indirect, supporting its reality. This is followed by a discussion of the possible causes of the phenomenon and in-depth analysis of illustrative cases. The authors outline a systematic approach to the clinical detection, evaluation and amelioration of individuals who exhibit binaural interference. Suggestions are furnished on improved techniques for evaluation of the binaural advantage in general and on sensitized detection of the disorder in particular. The book ends with recommendations for future directions. Given the adverse impact of binaural interference on auditory function and its occurrence in a significant subset of the population with hearing loss, as well as in some individuals with normal-hearing sensitivity, research on binaural interference only recently has begun to flourish, and adaptation of audiologic clinical practice to identify, assess, and manage individuals with binaural interference has yet to become widespread. The authors intend for the book to provide impetus for pursuing further research and to encourage audiologists to explore the possibility of binaural interference when patient complaints suggest it and when performing audiologic evaluations. The book is intended for practicing clinical audiologists, audiology students, and hearing scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Spoken Word Recognition covers the entire range of processes involved in recognizing spoken words - both in and out of context. It brings together a number of essays dealing with important theoretical questions raised by the study of spoken word recognition - among them, how do we understand fluent speech as efficiently and effortlessly as we do? What are the mental processes and representations involved when we recognize spoken words? How do these differ from those involved in reading written words? What information is stored in our mental lexicon and how is it structured? What do linguistic and computational theories tell us about these psychological processes and representations?The multidisciplinary presentation of work by phoneticians, linguists, psychologists, and computer scientists reflects the growing interest in spoken word recognition from a number of different perspectives. It is a natural consequence of the mediating role that lexical representations and processes play in language understanding, linking sound with meaning.Following the editors' introduction, the contributions and their authors are: Acoustic-Phonetic Representation in Word Recognition (David B. Pisoni and Paul A. Luce). Phonological Parsing and Lexical Retrieval (Kenneth W. Church). Parallel Processing in Spoken Word Recognition (William D. Marslen-Wilson).
