These authors concluded that stereoscopic depth is not to be conceived as a direct physiological phenomenon but as a psychical one, that is, the depth is produced by a psychophysical process. In this experiment, the stereoscopic vision arises solely through the means of imagined prolongations of the halfimages, which then in the usual stereoscopic manner would be referred to horizontally disparate retinal points.

The papers presented in this volume are concerned with ideal and practical techniques for the measurement of each of the selected visual functions and cover the following topics: visual acuity; refractive error; color vision; distance vision; phoria and ocular rotation; accommodative amplitude; night vision; visual fields; intraocular tension; stress tolerance; and clinical and laboratory measurement of visual functions (other than those mentioned)

It begins with an examination of the physiology of eye movement control and then examines the role of eye movements in vision, methods of recording eye movements, the relation of eye movements to the perception of motion, position, and kinds of visual stimuli. Specific fields such as target detection, search and scanning, reading behavior, and highest cognitive processes are examined.

Second, psychophysical applications of human electroretinography are given: rapid developments in human electroretinography during recent decades have greatly increased its value for investigating psychophysical problems. This review of the current status of electroretinography considers the response waveform, recording techniques, and data analysis.

The Department of the Air Force also requested comment on the desirability of routine screening for ocular changes in all its personnel working around microwave devices. Potential hazards of human exposure to microwave radiation are of considerable concern because large numbers of people in the military services and in industry work in the vicinity of microwave generators and also because people may be exposed to radiation from devices such as microwave ovens and diathermy devices used in physical therapy.

Each of these topics is discussed in a separate section of the report; each section focuses on issues related to screening industrial and military visual functions. The report concludes with summary recommendations for research.

The Committee on Vision requested information concerning their in-house research; this report summarizes the results of that survey and describes the type and amount of vision research being done in the military and government laboratories. References cited in this report indude those received as a result of that survey.

On December 11, 1985, the Committee on Vision brought together 14 leading investigators in vision research whose work embodies the integration of some of these newer models and methods. Participants illustrated how new approaches to fundamental visual processes have significantly improved our understanding of.spatial vision, stereoscopic depth perception, color consistency, and color vision.

Others are now using noninvasive techniques (e.g., positron emission tomography) to study local regions of brain activity in alert humans.

Another area of recent progress is the analysis of the spatial mosaic of photoreceptors. The sampling of the visual image by the photoreceptor lattice influences visual acuity and sensitivity.
