The Influence Of Reward Motivation On Self-control Behavior

People often face such problems in life: knowing that they have established a strict diet plan,but still cannot stand the temptation of food;knowing that their learning goals have not yet been completed,but still could not help but to catch up with the updated television drama series.This series of questions is related to a core concept of psychology: self-control.According to Roy F.Baumeister,who put forward this concept,self-control refers to the ability of individuals to control and transform their own impulses,habits,or automation to match ideals,values,morals,and social expectations,and to maintain longterm goals.Self-control is concerned by the majority of psychological researchers,mainly because of its value in social life.Research shows that if the individual has a high selfcontrol ability,he has good academic performance,a high level of self-esteem,a strong physical quality,and a more harmonious relationship with others;on the contrary,individuals with low self-control ability are faced with Eating disorders,dependence on addiction,and even violence.In self-control studies,dual-task paradigm is the most commonly used experimental paradigm.It is for the subjects to complete two seemingly unrelated self-control tasks and examine the impact of the previous task on the latter task.The basic logic is that if self-control requires energy consumption,then task one will consume the subject's self-control resources,thereby destroying his self-control performance in task two.However,the field of self-control research faces many challenges recently.First,is there a self-depletion effect? Evan Carter did not repeat the results of previous studies in the study.At the same time,23 laboratories engaged in self-loss studies in the world did not obtain satisfactory results.Secondly,after the task one in the dual task paradigm,if the subject is given a certain reward or energy supplement,can it improve the performance of the task two of the subject? Kurzban's research believed that task one consumes subject's blood glucose levels,and that supplementation with glucose can improve task two's performance later,but Gailliot et al.obtained different results.Finally,how does the motivation affect self-control behavior? Muraven et al.believe that providing reward motivation can overcome ego-depletion,but the current experimental evidence does not well explain the mechanism of motivation.In the current study,we aim to explore the above issues.The subjects used in this study were restrained dieters.The characteristics of this groups was they were intended to invest more cognition resources for food clues.The experimental paradigm was a dual task paradigm.Task one was food cue response paradigm.Task two was the classic Stroop paradigm.In Experiment 1,we examined whether the ego-depletion effect exists.Whether the participant consumed self-control in Task 1 had an effect on the performance of Task two.As a result,it was found that the subjects underwent self-control after watching the food pictures and destroyed the performance of task two,indicating that the self-depletion effect did exist.Experiment 2 examines whether incentive motivation affects self-control behavior.The task was the same as experiment one,but the bonus cues were added in task two.As a result,it was found that the participants responded faster to the trials with reward cues.This shows that the incentive incentives compensate for selfdestruction to some extent.Experiment 3 controls the proportion of reward clues on the basis of experiment 2.It was found that task two performed better only when the subjects developed a reward expectation rather than a simple stimulus-response linkage.The research results support the existence of self-depletion effects and further enrich the self-control related theories.The innovation of this research is to explore the internal process of incentive motivation adjustment self-control behavior for the first time through the use of incentive incentives,and this study uses experimental materials which is a picture in real life that easily leads to the failure of individual self-control,making the experiment more ecologically effective,and provides a certain theoretical basis for future prevention and intervention of self-control failure.
