- Abstract
- The results of two independent researches aimed at revealing of dynamics of neurophysiological (EEG) and psychophysiological (GSR) indices in the process of cognitive activity: 1) different types of conceptual transformations (“vertical” and “horizontal”) ( n = 34); 2) different types of perceptual scanning by the example of reflectivity/ impulsivity cognitive style ( n = 31) (subjects’ age – 17–33) are presented. The higher productivity of conceptual transformations is, the less complex EEG curve is. This can be interpreted as a tendency of energy expenditure decreasing in the observed frequency range. Reflective cognitive style is shown to be more cost-based form of cognitive functioning in comparison with impulsive one. The conclusion that the character of informational – energy ratios while fulfilling different types of cognitive activity depend on factor-mediator – mental efforts is drawn. The reduction of mental efforts results in energy expenditure decreasing, while their growth – in increasing of the last. Thus, informational characteristics of cognitive activity are basic, while energy ones are derivatives.
