Primate Hearing And Communication

Presents a comprehensive review of nonhuman primate audition and vocal communication. These are obviously intimately related topics, but are often addressed separately. The hearing abilities of primates have been tested experimentally in a large number of species across the primate order, and these studies have revealed both consistent patterns as well as interesting variation within and between taxonomic groups. Recent studies have shed light on how variation in anatomical structures along the auditory pathway relates to variation in auditory sensitivity. At the same time, ongoing studies of vocal communication in wild primate populations continue to reveal new insights into the social and environmental contexts of many primate calls, and the range of known primate vocalizations has increased dramatically with the development of more sophisticated and accessible auditory equipment and software that enables the recording and analysis of higher-fidelity and broader-band recordings, including documenting very high frequency (i.e. ultrasound) vocalizations. Historically the relative importance of primate calls has been evaluated qualitatively by the perception of the researcher, but new methods and approaches now enable a greater appreciation for how signals are used and perceived by the primates in question. The integration of anatomical and behavioral data on acoustic communication and the environmental correlates thereof has significant potential for reconstructing behavior in the fossil record. This confluence of factors and accumulating evidence for the sophistication and complexity in both the signal and its interpretation indicate that a book synthesizing this information across primates is warranted and represents an important contribution to the literature.

Communication is both a prerequisite and manifestation of social organization and in this sense several chapters of this volume are aimed to investigate the way vocal communication serves its ultimate function of maintaining social organization. Although manifold parallels exist to vocal communication in birds, additional mechanisms of vocalization are found in primates. Treating the various psychological, ecological, behavioral, and neurobiological aspects of vocalization this book provides an interdisciplinary approach for the understanding of biocommunication in primates including humans. Conceptual as well as methodological considerations are given in a balanced way. The addition of a comprehensive glossary gives an overview also to nonspecialists in this field.

More than 25 years ago, the first major review of primate communication appeared (Altmann, 1967). Since then, information on the communicative abilities of primates increased rapidly, resulting, 15 years later, in the appearance of the first volume in which signaling systems were analyzed in a broader variety of primate groups within an evolutionary perspective (Snowdon, Brown and Petersen, 1982). Seven years later, the first volume dedicated solely to primate vocal communication appeared (Todt, Goedeking and Symmes, 1988) and another four years later a volume followed in which nonverbal vocal communication in non-human primates and human infants was compared (Papousek, Jurgens and Papousek, 1992). None of these volumes, however, provided information about current technical advances in the field of bioacoustics, especially in digital sound analyzing systems, which offer primatologists, anthropologists and linguists nowadays a variety of rapid methods for analyzing human speech and non-human primate vocalizations in a quantitative and comparative way. Choosing the right method is difficult if a synopsis of these tools is lacking. Furthermore, information was particularly lacking on the natural signaling systems of two important primate groups, the prosimians and the apes. Likewise, new and unexpected insights into the ontogeny and evolution of vocal communication were gained during the past few years by the use of highly sophisticated sound analysis and statistical techniques.

Multimodal approach to primate communication with focus on its cognitive foundations and how this relates to theories of language evolution.

Neurobiology of Social Communication in Primates: An Evolutionary Perspective presents evidence on the neural basis of communicative behavior in primates, reevaluating the relationship between human language and animal communication in view of the linguistic abilities of chimpanzees. This book consists of 10 chapters. Chapter 1 discusses some of the persistent problems in evolutionary neurobiology of primate communication. The effects of brain lesions and stimulation on vocalization in New and Old World monkeys, relation between species differences in peripheral vocal structures and species contrasts in vocal performance, and anatomy and physiology of the nonhuman primate auditory system are reviewed in Chapters 2 to 4. Chapters 5 to 7 examine the effects of electrical brain stimulation on human verbal communication and facial expression, clinical data pertaining to language pathologies, and neural mechanisms of manual and oral control. The last three chapters summarize the materials presented in earlier chapters. This publication is recommended for neuroscientists, behavioral biologists, neurologists, psychiatrists, and students interested in the evolutionary heritage of human speech and language.

The Gestural Communication of Apes and Monkeys is an intriguing compilation of naturalistic and experimental research conducted over the course of 20 years on gestural communication in primates, as well as a comparison to what is known about the vocal communication of nonhuman primates. The editors also make systematic comparisons to the gestural communication of prelinguistic and just-linguistic human children. An enlightening exploration unfolds into what may represent the starting point for the evolution of human communication and language. This especially significant read is organized into nine chapters that discuss: *the gestural repertoire of chimpanzees; *gestures in orangutans, subadult gorillas, and siamangs; *gestural communication in Barbary macaques; and *a comparison of the gestures of apes and monkeys. This book will appeal to psychologists, anthropologists, and linguists interested in the evolutionary origins of language and/or gestures, as well as to all primatologists. A CD insert offers video of gestures for each of the species.
