| In real life,people will face many important decisions and judgments,and correct and scientific decision-making will lead to the solution of problems,the development of the cause,the improvement of the quality of life,and even the progress of mankind.However,there is always a decision-making bias that cannot be ignored when people make decisions.The basic anchoring effect is one of the categories.It is ubiquitous in various judgments and estimation tasks.This is because in the uncertain context,the decision maker will approach the anchor value with the estimation result to generate the estimation bias phenomenon.This phenomenon will have a greater impact on people’s lives and work,and even bring about unnecessary problems.In this paper,two studies have been designed on the basis of predecessors’ researches,aiming at exploring the conditions for the occurrence of the anchoring effect and the neural mechanisms during its occurrence.Study 1 discusses the influence of rationality of the anchor value and the familiarity of the problem on the anchoring effect in the task of estimating the number of daily living;and study 2 discusses the anchoring effect of the anchor value in the unfamiliar task context.Impact ERP studies.Research indicates:(1)From the question familiarity point,when the subjects are familiar with the problem,whether the anchor value is reasonable or unreasonable will not lead to the occurrence of the anchoring effect;when the subject is not familiar with the problem and the anchor value is unreasonable,There will be no basic anchoring effect;however,when the subjects are not familiar with the problem and the anchor value is reasonable,the anchoring effect will be generated.(2)From the results of EEG,there are significant differences between P1、N1 and N300 components in reasonable anchor group,unreasonable anchor group,and string group,supporting the choice of-access model. |
