The Effects Of Stress On Intertemporal Choice

Intertemporal choice referred to the individual at different time weighing and considering balance between the costs and the benefits, and then made judgment and choice.The study of intertemporal choice was first started in nineteenth Century by Philosopher.and until the last century later it attracted extensive attention including sociologists, economists and psychologists.Intertemporal choice was related not only to the person’s health, happiness and wealth, but also affected national and world economic prosperity and well-being.Study on the intertemporal choice can help people to understand in life the reason of unreasonable behavior, and to explore the cause of addiction to smoking, alcohol addiction, pathological gambling, overeating, attention.deficit hyperactivity disorder, such as a series of behavioral disorders and mental illness, fntertemporal choice behavior of individual was affected by many factors,such as emotion, frame effect. This study paid attention to the rate of timeOn the basis of previous studies, this study applied the software of E-primeThrough three experimental system to explore the influence of measurement scenario, time frame for intertemporal choice behavior, and whether the intertemporal choice of individual change under stress conditions.Combined with the subject status and external conditions to examine the intertemporal choice behavior of individual.Pre experiment Objective:Verify the previous study intertemporal choice when the "time inconsistency"phenomenon. Method:60subjects was chose from a University College of physical education, using the time frame2(specific time delay time of VS) single factor within subjects design, through participants’ option calculation time discount rate. Results: Participants in a specific time frame time discount rate was significantly higher than the delay time under the framework of the time discount rate. Conclusion:the dynamic inconsistency "phenomenon does exist" in intertemporal choice of the individual.Study1Objective:To investigate the loss situation whether there would be a "time inconsistency" phenomenon. Method:60subjects was chose from a University College of physical education.distributed to a2(income situation VS loss situation) x2(specific time frame VS delay time frame) of two factors within subjects design, through participants’ option calculation time discount rate. Results:the main effect measurement situation, interaction time frame experiment and measurement scenarios and time frame significantly. Conclusion: loss situation also appeared in intertemporal choice "time inconsistency" phenomenon, the intertemporal choice factors in the loss situation of the impact can not be ignored.Study2Objective:To study the effect of stress state under the condition of different individual intertemporal choice behavior. Method:60subjects chose from a University College of physical education,60subjects, distributed to a2(income situation VS loss situation) X2(specific time frame for the delay time of VS framework X2(VS) stress in normal state) of the three factor randomized design, through participants’ option calculation time discount rate. Results:1)no stress, intertemporal choice behavior of individual does not exist separately from the time frame in the profit and loss situation;2) compared to the normal state, the condition of stress was tested in a loss situation than gain situations are more likely to choose to close small selection;3) income situation under stress, the subjects than in normal condition are more likely to choose to close and small options, and this difference in the loss situation is opposite:participants in a specific time frame than in the delayed framework easier to choose a near smaller options, and this difference does not exist in the losssituation;4) the specific time frame, the subjects in the condition of stress than in normal condition are more likely to choose to close small options, and the delay time frame difference. Conclusion:the stress would affect the intertemporal choice of subjects, and the effect under different conditions of different.In conclusion, the effect of stress state period of individual choice span had significant interaction with the measurement scenarios and time frame, there were also differences impact on the intertemporal choice under different conditions, future research could investigate the neural mechanisms underlying these differences.
