There was investigated the influence of motivational complex on efficacy of intellectual activity of children (6-7 years old) measured in directed associative experiment. Three groups of children (n = 34) were distinguished in the study: (1) children which improved results after introducing of external motivation (reward for future success); (2) which made worse results; (3) which didn't change results. Three groups of Ss have different complexes of psychophysiological symptoms including indices of GSR and ECG recorded in the course of verbal activity. High verbal efficiency was correlated both with the indices of GSR and stochastic parameters of ECG as well as with the functional state mobilization. The data obtained is explained in terms of child's extraversion as a typological determinant.
Key words: intellectual activity, motivation, regulation of cardiovascular system, stochastic parameters of regulation, fractal index.
