The Relationship Between Estimation Strategy Switch And Central Executive Function

In the field of cognition,many studies have shown that people often use a variety of strategies to perform cognitive tasks,and the performance of their assignment depends on the tactics they use.It also has been found that there is switching cost in the conversion between the two strategies in recent years,but the mechanism is not clear.However,the relationship between the central executive function which play a coordinated role in advanced cognitive processing activities and switch cost of strategies is on the knees of the gods.This research which combined strategy casts paradigm with Stroop paradigm,discussed the stimulus-response interval(the response-stimulus interval,RSI)and inhibition of load effect on the strategy switch with 44 students of Soochow University as the subjects.Furthermore,it was investigated that the relationship between the policy switching cost and the central executive function(inhibition function,switch function and refresh function)under different RSI conditions and inhibitory loads.Finally,we draw the following conclusions.(1)There are still some difficulties in strategy switching cost and policy order in the mixed two digit multiplication estimation problem(SSD effect).It shows that the cost of strategic switching is related to the difficulty of the strategy and the characteristics of the title.(2)The influence of RSI to strategy switch is significant and RSI affects the relationship between strategy switching costs and the central executive function.(3)There are different degrees of correlation between the three sub components of the central executive function(inhibition function,conversion function and refresh function).It explains that the central executive function has obvious pertinence and selectivity to the estimation strategy.The relationship between RD strategy of switching costs and inhibiting function was significantly negative correlation under the condition of 900 ms.RU strategy switching cost significantly associated with the size of judgment task switching cost under the condition of 300 ms.The relationship between RU strategy switching costs and the refresh function of one-back task reaction time was significantly negative correlation under the condition of 600 ms.The relationship between RD strategy of switching costs and inhibiting function showed significant negative correlation under high load conditions and no load conditions.RU strategy switching costs are significantly associated with the conversion function ubder low and high inhibiting load conditions,and under the condition of no load significantly related to refresh function.The influence of the central executive function to estimate strategy switching has obvious pertinence and selectivity.(4)The inhibitory function has an impact on the strategy switching,that is,the different strategies of the different switching load have different cost.It illustrates that the suppression function plays a vital role in the strategy conversion process.This study has important theoretical significance and practical value.It can not only promote the establishment and improvement of the relevant theoretical model of strategy switching,but also provide scientific guidance for classroom teaching.On the one hand,it will promote the comprehensive understanding of the factors affecting the cognitive tasks of mathematical arithmetic.On the other hand,we can design an intervention program for the cognitive difficulties of mathematics learning from the perspective of the central executive function training.
