[Individual typological differences in human behavior under conditions of reward choice assoicated with risk].

[Article in Russian]


A choice between probability (100, 75, 50, 25, 10, 0%) and valuable reward were investigated in adult. In behavioral experiments, adult subjects put in a situation of a choice between greater, but risky prize and smaller, but received always, made the decision according to situational factors and specific features of character such as propensity to risk and care. In a situation of choice of behavioral strategy, subjects could be divided in "inclined to risk" and "careful". Tipologycal differences between groups were the greatest under conditions of 25% probability of getting a valuable reward. Probability prognosis was more efficient in persons "tended to risk", than in "careful" subjects. According to psychological tests, "impulsive" people appeared to be more inclined to risk than to cautiousness. For the group of persons that tended to cautiousness under conditions of 25% probability of getting a valuable reward, synchronism of EEG rhythms in the alpha and beta bands was revealed.
