Born March 26, 1944 in the city of Derbent, Dagestan ASSR, he graduated from the Faculty of Psychology of Moscow State University. State University (1976), Doctor of Psychology (1985), Professor (1989), Professor (1987) Department of Psychology and knowledge engineering, then the Department of Psychophysiology Psychology Department of Moscow State University, Moscow State University Professor Emeritus (2005). I. - a member of the European Society for Cognitive Psychology (s1989).
Areas of research: general psychology, psychophysics, psychophysiology of visual perception, color vision, discernment of flat configuration, the relationship of emotion and color, visual categorization. PhD thesis "The spherical model of color discrimination `and doctoral thesis," The perception of color (Mechanisms and models) "I. carried out under the supervision of Professor E.N.Sokolova. MI has developed a new model of color vision, based on the large dimensions (above-threshold) color differences. The model is a spherical surface in four-dimensional Euclidean space. Many colors defined basic psychophysical characteristics (hue, saturation, brightness, lightness) are given points on a spherical surface so that each psycho-physical characteristics of the respective one of the three spherical (angular) coordinates of the color point. At the same time, the Cartesian coordinates of the four color dots are neurophysiological mechanisms of encoding the color information in the human visual system. The channels are grouped in pairs: two channels (red-green and blue-yellow) for the transmission of chromatic information that is obtained from the analysis of the spectral composition of light emission, and two (light and dark channels) for transmitting achromatic information that is obtained from the analysis of the intensity of radiation . Each pair of channels forms a coherent system, so that an increase in the activity of neurons of one channel is always accompanied by inhibition of the activity of the neurons of the second channel, and vice versa. The total activity of the channel pairs is always constant and equal to the sum of the squares of the values ??of the individual channels of activity. Such a pair of neurophysiological channels, interconnected by spherical law, is one of the basic mechanisms of the visual system, designed for the analysis of not only the light emission, but also to highlight the configurational characteristics of the image signal for analysis orientation in the frontal plane.
