Self-Other Intertemporal Decision Preference And Influencing Factors Of Depression Groups

From the perspectives of neural mechanisms and behavioral outcomes,related theories on depression suggest that depressed groups may have a tendency to be short-sighted.Specifically,in intertemporal decision-making,individuals are more likely to give up long-term interests for immediate gratification.At the same time,depressed individuals have theoretical mental barriers,and have difficulties in perceiving and judging the state of others,which is reflected in the difficulty of inferring the decision-making preferences of others in decision-making.Based on previous studies,this study aimed to further understand the differences in preferences between depressed and healthy groups in making intertemporal decisions for themselves and others in different domains,as well as the related mechanisms that lead to differences in decision-making outcomes.In Experiment 1,we took 110 depressed patients and 100 healthy individuals as research objects,and examined the characteristics of depressed and healthy groups when they make decisions for themselves and others.The results showed that the depressed group showed a higher discount rate and stronger impulsiveness when making decisions for themselves and others,and both the depressed group and the healthy group showed a lower discount rate when making decisions for others than those who made choices for themselves.Condition.In the second experiment,100 depressed patients and 110 healthy individuals were taken as the research objects,and the decision-making domain was extended to the environmental domain to examine whether the differences in intertemporal decision-making between depressed and healthy groups were consistent across domains.On the basis of the first two experiments,the third experiment took 106 depressed patients and 117 healthy individuals as the research objects,and on the basis of examining the decision-making preferences of the two types of subjects,the influence of social exclusion on the degree of depression was investigated,and the perception of time was explored.The role of depression and healthy individuals in intertemporal decision-making,so as to explore the mechanism by which depression affects intertemporal decision-making.The results of the study show that:(1)Compared with healthy groups,depressed groups prefer immediate gratification in intertemporal decision-making,and the delayed discount rate is higher.(2)In the fields of money and environment,the discount rate of the depressed group and the healthy group is higher than that of making decisions for others.(3)The time discount rate of the two groups in the money domain is significantly lower than the time discount rate in the environment domain.(4)Social exclusion has a significant positive impact on the degree of depression.The more social exclusion in daily life,the higher the depression degree of the subjects.(5)The perceived time length of intertemporal decision-making in the depressed group was significantly higher than that in the healthy group.This study examines the difference in intertemporal choice between depressed and healthy individuals,and on this basis,examines the performance of this difference in different domains,enriches the domain-specific content of intertemporal decision-making,and further explores depression Behavioral mechanisms that affect intertemporal decision-making.This result provides a theoretical basis for us to deeply understand the decision-making mode of depressed individuals and to make more targeted decisionmaking suggestions for depressed individuals.
