“…Energy is spent for maintenance in excitation stateof two centers of a brain, and also for ensuring continuous interaction between them (Csikzentmihalyi, 1990). At simultaneous perception of a large number of objects, as show M. Bulatova, I. Utochkin, distortion of individual object perception occurs (Bulatova, Utochkin, 2013). On the other hand, materials of empirical research confirm the fact of automation of attention as main effect of learning.…”

Research objective is to determine dependence of professional multidimensionality on the person'scognitive abilities, to develop an essence and a cognitive orientation of multidimensional thinking, to study cognitive opportunities of memory and attention. The leading method of research is the system analysis of essence of multidimensional thinking. In the work the theoretical materials about multidimensional thinking published in the press, results of the experimental studies connected with detection of functionality of memory, attention and thinking were used. The cognitive basis of professional multidimensionality is made by the multidimensional thinking directed to extraction of new meanings by simultaneous actualization and correlation of several local semantic spaces. Nizhnekamsk office of Gertsen university UNESCO department research associates under the leadership of the author of this article made a contribution to research of cognitive bases of multifunctionality, multitasking and integrity. The results received in article can be used forworking out the technology of the expert's professional self-development based on multidimensional thinking and the advanced cognitive abilities.

We measure the orientation tuning of red-green colour and luminance vision at low (0.375 c/deg) and mid (1.5 c/deg) spatial frequencies using the low-contrast psychophysical method of subthreshold summation. Orientation bandwidths of the underlying neural detectors are found using a model involving Minkowski summation of the rectified outputs of a bank of oriented filters. At 1.5 c/deg, we find orientation-tuned detectors with similar bandwidths for chromatic and achromatic contrast. At 0.375 c/deg, orientation tuning is preserved with no change in bandwidth for achromatic stimuli, however, for chromatic stimuli orientation tuning becomes extremely broad, compatible with detection by non-oriented colour detectors. A non-oriented colour detector, previously reported in single cells in primate V1 but not psychophysically in humans, can transmit crucial information about the color of larger areas or surfaces whereas orientation-tuned detectors are required to detect the colour or luminance edges that delineate an object's shape.
