The Information Processing Process Of Risk Decision Making For Self And Others:Evidence From Eye Movement

Risk decision making has always been a hot point in decision making research.How do people behave when facing risky choices,and what mechanism underlies decision making under conditions of risk? In everyday life,we make decisions for others as often as for ourselves.In risky situation,people can benefit directly from a good choice that was made for themselves,and the establishment and maintenance of harmonious social relationships rely on the sensible decisions that people made for others under risk.Researches explore the influence factors and risk preference of risk decision making through experiments.The debate on whether risk decision making is unlimited rationality or bounded rationality has never stop.And the question about how exactly people making decisions have perplexing us all the time.With the deeper research on decision making the study on risk decision making progress has gradually been the key point of the research.This study discussed the information processing process of self-others risk decision making used eye movement technology and try to get explanations for the relative theory of risk decision making.In this study,we designed two experiments to explore the information processing process of risk decision making for self and others.We use the Eyelink 1000 eye-tracking equipment to record.In study1 a,we using 3(decision-makers: self,close friend,stranger)×2(task framework: positive,negative)between-subjects design.In study 1b,we using 3(decision-makers: self,close friend,stranger)× 2(task framework: positive,negative)× 2(calculate difficult: high,low)mixed design to explore the calculate difficult influence on decision-making information processing.In study2 a,we using 3(decision-makers: self,similar others,dissimilar others)×2(task framework: positive,negative)between-subjects design.In study 2b,we using 3(decision-makers: self,similar others,dissimilar others)× 2(task framework: positive,negative)× 2(calculate difficult: high,low)mixed design to explore the calculate difficult influence on decision-making information processing.Through data analysis,the conclusions were as followed:Firstly,in the gain frames,there were shorter fixation time and less fixations for oneself than for friends and stronger.Making decisions for oneself and friends pay more attention on probability.Making decisions for stronger pay more attention on adventure.In loss frames,in the four interest areas,there were no differences in making decisions for oneself and others.Secondly,in the gain frames,there were shorter fixation time and less fixations for oneself than for similar others and dissimilar others.There were no differences for similar others and dissimilar others.In loss frames,there were no differences for similar others.there were shorter fixation time and less fixations for low lose interest area than high probability interest area.Lastly,framing effect had significantly influence on self-others risk decision-making process of information processing.
