Research on the decision-making process of individuals with different types of behavioral activation

Objective To explore the decision-making process in different types of behavioral activation (BAS) individuals. Methods According to the behavioral inhibition/activation system scales of China, 27 low BAS, 32 moderate BAS and 26 high BAS individuals were enrolled. Three different kinds of decision tasks (low-risk, high-risk and ambiguity) were programmed with E-Prime, at the same time recorded the scores of earnings, preference selection, decision-making strategy. Results Under low-risk decision, there was significant differences among low, moderate and high BAS groups (low BAS group(54.00±8.15), moderate BAS group(32.63±8.94), high BAS group(27.69±12.12), F=2.240, P 0.05). Under low-risk decision, there were significant differences on stay strategy (low BAS>moderate BAS, high BAS group, F= 3.107, P low BAS group, F=2.309, P 0.05). Conclusion Under the low-risk decision-making, low BAS individuals are easier to get more earnings.Moderate and high BAS individuals are easier to change the decision-making strategy than low BAS individuals.
