(cont.) However, further results in the third and fourth studies suggested a role for harmonic resolvability in pitch discrimination, inconsistent with the lack of dependence on resolvability of the modified autocorrelation model. In normal-hearing subjects at high stimulus levels and in hearing-impaired subjects, a wider spacing between adjacent frequency components, related to a reduction in frequency selectivity, was required to yield accurate FO discrimination performance. Thus, resolved harmonics may be necessary for accurate FO encoding, and the pitch discrimination deficit associated with sensorineural hearing loss may be related to a reduction in frequency selectivity. These results support spectral or spectrotemporal pitch models that derive FO from resolved harmonics, or a place-dependent temporal model whereby peripheral filter bandwidths limit the range of detectable periodicities. Because spectral processing plays an important role in pitch discrimination, hearing-impaired and cochlear-implant listeners may benefit from hearing-aid fitting procedures and cochlear-implant processing algorithms that emphasize or enhance spectral place cues.

Although pitch has been considered an important area of auditory research since the birth of modern acoustics in the 19th century, some of the most significant developments in our understanding of this phenomenon have occurred comparatively recently. In auditory physiology, researchers are now identifying cells in the brainstem and cortex that may be involved in the derivation of pitch. In auditory psychophysics, dramatic developments over the last few years have changed our understanding of temporal pitch mechanisms, and of the roles of resolved and unresolved harmonics. Computational modeling has provided new insights into the biological algorithms that may underlie pitch perception. Modern brain imaging techniques have suggested possible cortical locations for pitch mechanisms. This timely volume brings together the more recent findings, while emphasizing their relation to the discoveries of the past. It brings together insights from several different methodological areas: physiology, psychophysics, comparative, imaging, etc., in addressing a single scientific problem. Pitch perception can be regarded as one of the main problems of hearing, and the multidisciplinary approach of the book provides a valuable reference source for graduate students and academics.

The International Symposium on Hearing is a highly-prestigious, triennial event where world-class scientists present and discuss the most recent advances in the field of hearing research in animals and humans. Presented papers range from basic to applied research, and are of interest neuroscientists, otolaryngologists, psychologists, and artificial intelligence researchers. Basic Aspects of Hearing: Physiology and Perception includes the best papers from the 2012 International Symposium on Hearing. Over 50 chapters focus on the relationship between auditory physiology, psychoacoustics, and computational modeling.

Pitch perception plays an important role in many complex auditory tasks including speech perception, music perception, and sound source segregation. Because of the protracted and extensive development of the human auditory cortex, pitch perception might be expected to mature, at least over the first few months of life. This dissertation investigates complex pitch perception in 3-month-olds, 7-month-olds and adults - time points when the organization of the auditory pathway is distinctly different. Using an observer-based psychophysical procedure, a series of four studies were conducted to determine whether infants (1) discriminate the pitch of harmonic complex tones, (2) discriminate the pitch of unresolved harmonics, (3) discriminate the pitch of missing fundamental melodies, and (4) have comparable sensitivity to pitch and spectral changes as adult listeners. The stimuli used in these studies were harmonic complex tones, with energy missing at the fundamental frequency. Infants at both three and seven months of age discriminated the pitch of missing fundamental complexes composed of resolved and unresolved harmonics as well as missing fundamental melodies, demonstrating perception of complex pitch by three months of age. More surprisingly, infants in both age groups had lower pitch and spectral discrimination thresholds than adult listeners. Furthermore, no differences in performance on any of the tasks presented were observed between infants at three and seven months of age. These results suggest that subcortical processing is not only sufficient to support pitch perception prior to cortical maturation, but provides adult-like sensitivity to pitch by three months.

This volume will cover a variety of topics, including child language development; hearing loss; listening in noise; statistical learning; poverty; auditory processing disorder; cochlear neuropathy; attention; and aging. It will appeal broadly to auditory scientists—and in fact, any scientist interested in the biology of human communication and learning. The range of the book highlights the interdisciplinary series of questions that are pursued using the auditory frequency-following response and will accordingly attract a wide and diverse readership, while remaining a lasting resource for the field.

The Sense of Hearing is a truly accessible introduction to auditory perception that is intended for students approaching the subject for the first time, and as a foundation for more advanced study. The second edition has been thoroughly revised throughout, and included new chapters on music, hearing impairment, and a new appendix describing research methodologies. In clear and authoritative prose, the fundamental aspects of hearing are addressed. The reader is introduced to the nature of sound and the spectrum, and the anatomy and physiology of the auditory system. Basic auditory processes including frequency selectivity, loudness and pitch perception, temporal resolution, and sound localization are explained. The reader is led to an understanding of the remarkable abilities of the auditory system in a systematic and coherent way. In subsequent chapters, it is shown how complex processes, such as perceptual organization, speech perception, and music perception, are dependent on the initial analysis that occurs when sounds enter the ear. Finally, a chapter on hearing impairment provides an introduction to disorders of the auditory system. The text benefits from 162 original illustrations, including uncluttered diagrams that illuminate auditory mechanisms. An extensive glossary provides definitions of technical terms. The emphasis is on explanation and clarity of style throughout, making The Sense of Hearing an essential resource for students and educators involved in this sometimes challenging field.

The Psychology of Music serves as an introduction to an interdisciplinary field in psychology, which focuses on the interpretation of music through mental function. This interpretation leads to the characterization of music through perceiving, remembering, creating, performing, and responding to music. In particular, the book provides an overview of the perception of musical tones by discussing different sound characteristics, like loudness, pitch and timbre, together with interaction between these attributes. It also discusses the effect of computer resources on the psychological study of music through computational modeling. In this way, models of pitch perception, grouping and voice separation, and harmonic analysis were developed. The book further discusses musical development in social and emotional contexts, and it presents ways that music training can enhance the singing ability of an individual. The book can be used as a reference source for perceptual and cognitive psychologists, neuroscientists, and musicians. It can also serve as a textbook for advanced courses in the psychological study of music. - Encompasses the way the brain perceives, remembers, creates, and performs music - Contributions from the top international researchers in perception and cognition of music - Designed for use as a textbook for advanced courses in psychology of music
