To determine the influence of the otolith organs on visually perceived direction of space the constant and variable errors of normal persons and deaf persons with bilateral labyrinthine defects during nineteen positions of body tilt within plus or minus 90 degrees of gravitational vertical were compared. The general perceptual pattern was similar for the two groups, although that of the labyrinthine-defective group was found to be more variable, and greater E- and A-effects were manifested during several of the tilt positions. A significantly larger E-effect was observed in those subjects (L-Ds) with little or no ocular counterroll. (Author).

The purpose of the experiment was to study the influence of otolith and nonotolith information in the perception of the visual horizontal during rotation. Five normal men and five men with defective labyrinthine function acted as observers. All measurements were made in a room which could be rotated. Initial, static measurements were made while the men stood erect in the stationary room. Similar measurements were made during rotation while the observer stood on a platform set to the resultant horizontal with head and body aligned with resultant force. Data were also obtained with three other combinations of head and body position. This procedure was designed to produce two situations for the normal men in which otolith and nonotolith information were synergistic and three others in which they were antagonistic. The results showed that the perception of the visual horizontal during rotation in this situation is quite different from that found when the observer is rigidly supported in a chair during rotation. Settings to the visual horizontal during rotation were not systematically related to differences in head and body position nor were there significant differences between the normal and L-D men. The results show that nonotolith information predominates in this experimental situation. Furthermore, the data suggest that the spatial orientation of a pilot strapped in a cockpit may be somewhat different from his spatial orientation when he is standing on a rotating space platform.

Annotation Topics presented were: Ultrastructural features of the two maculae with special emphasis on the neuromediators involved in vestibular signal processing; Review of the physiology of the otolith organs and some fascinating and unexpected roles of these structures in current clinical symptoms; Principal otolith-related syndromes drawing on clinical experience; Development of thoughts on the role of otoliths in movement perception; Clinical and instrumental investigation of otolith function and a critical appraisal for the tests used in vestibulometric practice with emphasis on the experience in eccentric rotatory testing; Use of the subjective visual vertical test, off-vertical axis rotation and click-evoked myogenic potentials as tools for functional investigations of the otolith organs. This volume provides an exhaustive view of the field in vestibulology, not only for neurophysiologists, otologists, neurologists, and kinesitherapists who are specialized in vestibular rehabilitation, but also for geriatrists and specialists in space medicine.

The function of the vestibular system is not as obvious as those of vision, hearing, touch or smell. Vestibular dysfunction, however, is clearly apparent where lesions are present. It is probably for this reason that the vestibular sense was not discovered until the nineteenth century and that clinicians have continued to playa major role in basic vestibular research right up to the present. The relationship between basic and clinical research is certainly stronger in the vesti bular field than in that of tactile sensation, for instance, as testified by the work of clinicians as MENIERE, BREUER, BARANY, DEKLEIJN and FRENZEL. In this respect the situation is similar in vestibular physiology and in endocrinology, and for the same reason. This second part of the vestibular volume of the Handbook of Sensory Physio logy will be of interest to neurologists, otologists, neurosurgeons, ophthalmologists and physiotherapists on the one hand, and psychologists, physiologists, engineers and aviation specialists on the other. For a full understanding of Part 2, it is necessary to have assimilated the basic anatomy, physiology, and biochemistry of Part 1.

This volume was designed to focus on the problems of perception and originally was to have been solely edited by Professor Hans-Lukas Teuber who was a member of the editorial board which initiated production of the Handbook. Accordingly, he issued invitations to a number of researchers III perception asking them to contribute chapters written in a style described III his words: " . . . Ire hope that no author lI'ill feel COl/strained to undertake a major search of the literature: he could In'ite, instead. on an area in which he has been quite actire himse?t~ and II'here most of the issues are immediately obt"ious to him. In this Iray, the IITiting of the chapter should be cnjoyable rather than a chore . . it should result in a personal account of the state of a given area rather than in an encyclopedic treatise . . . the field deserves this sort of summary ret'iell", particularly (f it is pointed toward the future and speeds the convergence of det'elopments in sensory physiology and psychological studies of perception, " With the growing burden of national and international commitments includ ing departmental headship, Professor Teuber felt that it would be wise to share the editorial responsibilities for this volume and accordingly, asked Professors Richard Held and Herschel Leibowitz to co-edit the volume with him in the same spirit as outlined in his invitation to authors. They agreed to help in this task.

Often defined as communication without words, non-verbal communication (NVC) refers to all aspects of a message which are not conveyed by the literal meaning of words. Both written and spoken communication can be nonverbal. The main types of NVC are chronemics, kinesics, paralinguistics, proxemics and semiotics. Culture, gender and social status influence non-verbal communication. NVC also includes object communication and haptics or touch. Paralinguistic mechanisms include intonation, stress, rate of speech, and pauses or hesitations; non-linguistic behaviours include gestures, facial expressions, and body language, among others. This book brings forth new and important research in this field.
