| Abstract: | In work the features of the biopotentials spatial organization are surveyed at successful and unsuccessful (abandoning or bad quality of a product) implementation of creative imagination in conditions of information over saturation. Two groups of the examinees have taken part in experiments: "professionals" (23 able-bodied examinees--students of faculty of an art graphics) and "nonprofessionals" (34 men, which specialty were not linked to systematic visual imagination). During experiment the examinees should mentally frame a visual object on the basis of two simple graphics units--right angle and diagonal, and after EEG registration to draw it on a paper and to give a title. The total number of units exceeded 7 +/- 2, i.e. the possibility of information processing at a realized level was unreal that reduced in necessity of connection of mechanisms of not realized information processes. Estimated quality of a framed product from the point of view successful and unsuccessful of implementation of the job and conforming to each of these variants of a feature of the EEG spatial organization, which shunted with the help of portable telemeter installation "SIT-EEG" from 24 items convexital surface of a head. Is shown, that at successful performance of the job in comparison with unsuccessful for "professionals" biopotentials spatial organization parameters--spatial synchronization (linear processes) and spatial disorder (the nonlinear processes) strengthen (in relation to a background) in frontal-temporal areas of the right hemisphere and parietal-occipital left ones. For "nonprofessionals" the value of these parameters was enlarged in an inverse direction: in frontal-temporal areas of the left hemisphere and in the right parietal-occipital. At unsuccessful performance of the jobs for "professionals" the body height ofbiopotentials spatial disorder almost in all cortical zones was marked, for "nonprofessionals" of change were weak. The between group differences in all situations for parameters ofbiopotentials coherence and spectral power are found also for "Informational - power" parameter mirroring a level of power expenditures of a brain on implementation of information processes. The obtained data are treated from the point of view ofelectroencephalographic correlates of successful and unsuccessful implementation of the job by "professionals" and "nonprofessionals" for creative imagination in conditions of information over saturation. |
