个体行为抑制-激活对其风险决策加工策略的影响研究
Behavioral Inhibition and Activation Effect on the Risk Decision -making Process Strategy
摘要
Abstract
Objective To investigate the effect of behavioral inhibition/ activation system( BIS/ BAS)and risk decision - making process strategy. Methods We enrolled 347 healthy people who received physical examination in the Affiliated Hospital of Qingdao University from January 2013 to October 2014. According to the evaluation by BIS/ BAS scale,we selected the subjects that were among both 15% highest BIS scorers and 15% highest BAS scorers and assigned them into high score group (n = 27);we selected subjects that were among both 15% lowest BIS scorers and 15% lowest BAS scorers and assigned them into low score group(n = 25). High - risk decision test and low - risk decision test were conducted on both groups,and gain -loss of decision making,choice preference and strategy pattern were also recorded. Results The two groups were not significantly different in the scores of keeping strategy,abandoning strategy and changing strategy under low - risk decision - making condition (P > 0. 05);the two groups were significantly different in the scores of keeping strategy,abandoning strategy and changing strategy(P < 0. 05)under high - risk decision - making condition;the scores of keeping strategy,abandoning strategy and changing strategy of the two groups under high - risk decision - making condition were significantly different from those under low- risk decision - making condition(P < 0. 05). The two groups were not significantly different in the scores of gain - loss and choice preference under low - risk decision - making condition( P > 0. 05);the two groups were significantly different in the scores of gain - loss and choice preference under high - risk decision - making condition(P < 0. 05);the scores of gain - loss and choice preference of the two groups under high - risk decision - making condition were significantly different from those under low - risk decision - making condition( P < 0. 05). Under low - risk decision - making condition,BIS score was positively correlated with the scores of choice preference and keeping strategy(P < 0. 05),and was negatively correlative with the score of changing strategy(P < 0. 05);BAS score was negatively correlated with keeping strategy( P < 0. 05),but was negatively correlated with the score of changing strategy. Under high - risk decision - making condition,BIS score was positively correlated with the score of abandoning strategy(P < 0. 05),but was negatively correlated with the score of changing strategy(P < 0. 05);BAS score was negatively correlated with the score of abandoning strategy(P < 0. 05),but was positively correlated with the score of changing strategy( P < 0. 05). Conclusion Risk aversion and getting gains are important mechanisms of individual decision,and with the increase of risk,decision - making tends to be more conservative and uncertain. Under low - risk condition,BIS has more significant control effect on individual decision making,with higher strategy stability;under high - risk decision,BAS has more significant control effect on individual decision making,showing higher strategy instability.关键词
