Research On The Effect Of Coding Mode For Movement Visual Memory Under Signal Detection Theory

In this study,the learning-recognition paradigm was adopted to study movement visual memory by using motion pictures as experimental materials,to explore whether the effects of different coding methods on movement visual memory were different across age groups.For people with different sports experience,as some people have long-term sports experience,it is explored whether their inherent sports experience will have positive influence on the effect of action visual memory.With the continuous implementation of relevant national policies,schools pay more attention to physical education.In China,there are abundant research results on physical education teaching methods.Although there have been a lot of relevant studies on movement memory,there are not many experimental studies on how to integrate coding methods into movement memory.Moreover,there are also few applications of signal detection theory in the field of sports,so relevant theoretical researches are lacking.Through sorting out and analyzing relevant research results,this paper presents domestic and foreign studies on the influence of relevant coding methods on motor memory,and puts forward future prospects.The purpose of this study is to draw the attention of the academic circle to the aspects related to action memory,so as to provide theoretical reference for further in-depth and systematic research.This study is based on the theory of signal detection.In the experiment,the third grade of primary school,the second grade of middle school,the second grade of high school,the college students and the college students majoring in physical education were randomly selected as the experimental group.The total number of subjects is254.Among them,except college physical education students,the rest of the students are ordinary students without sports expertise.The research materials used in the experiment were 150 action pictures taken by ourselves.After screening,a total of 90 pictures were selected as experimental materials.The first category was exercise pictures,with a total of 10 pictures.The second category is a total of 40 action pictures that need to be remembered during the learning stage in the formal experiment,and the remaining 40 pictures are used as interference pictures.Before the experiment,the subjects were told that all the pictures were memorized by overall coding.In the experiment,all participants were asked to memorize the 40 gestures in differentcoding ways.Take a five-minute break after the memory task.The experimental results show that :(1)The memory effect of action pictures in the primary school group under the overall coding condition is better than that under the partial coding condition.The students in the middle school group remembered the action pictures better under the whole.The students in the high school group remembered the action pictures better under the whole coding condition than the action pictures under the part coding condition.There was no significant difference in the memory effect of action pictures between the college normal group and the college sports group under the condition of partial coding and the condition of overall coding.(2)Among the public sports groups of primary school,middle school,high school and university,the indicators of part H,whole H,part d ’,whole d ’,part RT,whole RT,part ACC and overall ACC were affected by age factors and showed significant differences.(3)There was no significant difference in the memory effect of action pictures between the college sports group and the college public sports group.Based on the results,the following conclusions can be drawn :(1)Different coding methods have an impact on students’ action visual memory.The overall coding effect was better for primary to high school students.College students speculate that due to the influence of individual memory habits and experience,there is no significant difference under different coding conditions.Therefore,the favorable processing method for college students’ action visual memory needs to be further demonstrated.However,both the whole coding and the partial coding need to be combined with the whole method and the decomposition method to achieve better teaching effect.(2)Students at different ages have different effect on movement visual memory.Age has certain advantages in motor visual memory learning,and high school is the peak of memory development.(3)The movement visual memory effect of students with different sports experience showed no significant difference.It is speculated that due to negative transfer,the existing motion experience has a negative effect on the formation of new motion pictures.This similarity in experience hinders the acquisition of movement visual memory.
