The Effects Of Decision Makers' Role Status Change On Decision Making Under Different Experience Conditions

As the decision-making environment becomes more and more complex,individual decision-making are no longer suitable for more difficult decision tasks.In many cases,comparing to individual decision-making,group decision-making can fully consider the overall decision-making context and make better decision-making due to group members' richer experience and knowledge.Dyadic decision-making is the smallest group decision-making and has its own mechanism and influencing factors.However,there are few studies on dyadic decision-making and the research on its influencing factors is very limited.Therefore,this study mainly explores the influence of changes in the role of decision makers on dyadic decision-making in different experience contexts.The study included a total of three experiments.In Experiment 1,both participants did not have experience and were asked to make two rounds of simulated investment decisions under the condition of partners and the condition of the leader and subordinate.The results showed that,under the leader's conditions,the decision-making team had reached an agreement in less round;after the decision maker was assigned to the leader role,he would insist more on his own decision in the decision-making process.In the second experiment,a simulated investment decision was made under the condition that one subject had experience while the other not,and there were three experimental conditions:leader with experience,leader without experience,and no leader.The results showed that participants with experience adhere to their own choices more than inexperienced ones;in the condition of experienced leaders,the decision-making team reached agreement with the least number of rounds;the results of the team's decisions tended to be the results of the leaders' decisions.In the third experiment,two participants underwent a set of simulation investment decisions under the conditions of both had experience.there were three experimental conditions:the leader learned Type I experience,the leader learned Type II experience and a control group without leader.The results showed that when both participants had experience,decision-making team with a leader reached agreement in less rounds the decision-making team without a leader;the results of the team's decisions resembled the experience type learned by the leader.In summary,this study draws several important conclusions:(1)Decision maker's role status influences the dyadic decision-making process and results.When the decision maker is a leader,the probability of changing the initial decision is significantly lower than that of the subordinate.The rounds of reaching agreement in a condition with leader is significantly lower than that in a condition without leader.And the decision-making team' final decision result tends to the leader's result.(2)Decision makers' experience has an impact on the dyadic decision-making process and results.When both participants had experience and both participants had no experience,there was no significant difference in the probability of decision makers changing initial decisions,but when only one decision maker has experience,the experienced participants change the initial decision probability significantly lower than the inexperienced ones.In addition,The rounds of reaching agreement rises in the experiment conditions that neither of the participants has no experience,one of the participant has experience,and both of the participants have experience,in the condition that neither of the participants has experience,decision making team reaches agreement in minimum number of rounds.
