There has been growing acceptance of the insight that the methods so far used in the testing of visual functions have been inadequate when it comes to specific problems and should, therefore, be supplemented with more specialised methods for dynamic testing. As long as two decades ago, large-scale mass screening produced evidence to the effect that visual acuity, so far exclusively determined by means of still samples, was not identical with visual acuity in the ocular pursuit of moving targets (dynamic visual acuity). In other words, vision testing can, at present, provide little informa tion on an individual's capability of identification, appreciation, and judge ment of mobile objects. Spatial, three-dimensional perception of moving targets, hereafter re ferred to as dynamic stereoacuity, is the particular subject on which findings are reported in this article. Findings of that kind are of considerable relevance to everyday life, since many of the phenomena that have to be three-dimensionally perceived in private life and in occupational practice, are in movement. So far, dynamic stereoacuity has never been systematical ly studied and is still a blank space on the maps of ophthalmology and physiology. This is equally true for dynamic stereoscopy in binocular vision as well as for perception on the basis of movement parallax, a phenomenon of differentiated contour displacement within a given field of vision which is also available to the monocular individual under conditions of head or body or object movement within the visual space.

This is the second of two edited volumes from an international group of researchers and specialists, which together comprise the edited proceedings of the First International Conference on Engineering Psychology and Cognitive Ergonomics, organized by Cranfield College of Aeronautics at Stratford-upon-Avon, England in October 1996. The applications areas include aerospace and other transportation, human-computer interaction, process control and training technology. Topics addressed include: the design of control and display systems; human perception, error, reliability, information processing, and human perception, error, reliability, information processing, and awareness, skill acquisition and retention; techniques for evaluating human-machine systems and the physiological correlates of performance. While Volume one is more clearly focused on the domain of aviation and ground transportation, Volume two is concerned with human factors in job and product design, the basics of decision making and training, with relevance to all industrial domains. Part one opens with a keynote chapter by Ken Eason. It is followed by Part two dealing with learning and training, while Part three reflects the rapidly growing area of medical ergonomics. Part four entitled 'Applied Cognitive Psychology' is biased towards human capabilities, an understanding of which is central to sound human engineering decisions. Part five firmly emphasizes equipment rather than its human operators.

The broad and developing scope of ergonomics - the application of scientific knowledge to improve people's interaction with products, systems and environments - has been illustrated over the past 15 years by the books which make up the Contemporary Ergonomics series. Presenting the proceedings of the Ergonomics Society's annual conference, the series embraces the wide range of topics covered by ergonomics. Individual papers provide insight into current practice, present new research findings and form an invaluable reference source. The volumes provide a fast track for the publication of suitable papers from international contributors. These are chosen on the basis of abstracts submitted to a selection panel in the autumn prior to the Ergonomics Society's annual conference held in the spring.

Light Pollution, Urbanization and Ecology presents a comprehensive review of light pollution, including scientific research on the ecological impacts of artificial illumination in urban regions. Chapters cover such topics as general ecological aspects, plants, invertebrate and vertebrate biology, and environmental and landscape architecture aspects of this interesting and important topic.

This is a composition of papers presented at the Annual Conference of the Ergonomics Society. Featured is a broad spectrum of research from many of the leading specialists in fields including consumer ergonomics and organization ergonomics.
