The Influence Of Cognitive Need And Self-control On Advice Taking Under Ego Depletion

To make a right decision,you often need to listen to others' advice.In previous studies advice taking was regarded as the process of interpersonal interaction.That is,advice-taking process is an important analytical processing.In this process,besides personality traits of decision makers and adviosrs,the characteristics of cognitive processing also have a remarkable effect on advice taking.However,only few studies have examined the effect of cognitive processing characteristics on advice taking.According to JAS paradigm,the process of advice taking is ultimately the process of weighting and integrating decision makers' initial decision and others' advice.This process requires some advanced psychological functions,such as analytical processing and self-control.Individuals may resist advices if their self-control are too strong,and lack of self-control will cause them adopt advices without thinking.Therefore,we believe that the process of advice taking is closely related to self-control.Recent studies about self-control and decision-making have found that ego depletion can lead to risk-taking behavior and impulse decision.However,there are few studies about the effects of ego depletion on advice taking.Then,compare with ordinary times,is there any difference of their adoption tendencies when decision-makers estimate suggestions under the condition of cognitive fatigue and insufficient mental energy? H?usser(2016)have studied the effects of sleep deprivation on advice taking,found that people who were deprived of sleep adopted more advice from others than those who had adequate sleep.Sleep deprivation is actually a loss of self-controlled resources.So we speculate that ego-depletion may have some effect on the adoption of recommendations.The studies of ego depletion recovery have found that the negative effect of depletion could be compensated by inducing individual's existing energy and motivation.Therefore,it can be considered that if individual's characters of control resources is different,such as self-control and cognitive need,the impact of egodepletion would be different.In this study,using JAS paradigm,two experiments were designed to investigate the impact of self-control and cognitive needs on advice taking under ego depletion.In experiment 1,the independent variables were ego depletion(yes,no),self-control((high,low)and advisors ability(high,low).In experiment 2,the independent variables were ego depletion(yes,no),cognitive need(high,low)and advisors ability(high,low).The dependent variable was WOA.Self-control and need for cognition to be measured separately using a scale,in which the top 30% of scores are high and the latter 30% are low.The ego depletion in this two Experiment was manipulated by a Stroop task,which require participant to judge whether the color of the word is congruent with its meaning.This task had been consistently proved to be effectively distinguish high and low control resources in previous researches.In the current study,participants assigned to high depletion condition completed 180 trails,which consisted of 100 incongruent trials and 80 congruent trails,whereby those in low depletion condition finished 180 congruent trials.After completing the Stroop task,participants were required to answer three manipulation checks before working on the distance estimation tasks.The results showed that:(1)the ego depletion individuals took more advice than no ego depletion individuals.(2)Individuals with low self-control ability adopted more advice than those with high self-control ability.(3)Individuals with low cognitive need adopted more advice than those with high cognitive need.(4)Decision makers adopted more advice from high ability advisors than from low ability advisors.
