A Study On The Development Of Action Memory Directed Forgetting In Primary School Students

Directed forgetting is a category of intentional forgetting,referring to its directed and intentional nature.Combing through the previous research results,the research materials are more verbal tasks and picture tasks,but there is little research on the motor materials in people's daily life.In the existing studies on directed forgetting of action memory,there is still a lack of supporting research for primary school students.However,in the study of primary school students,the subjects are mainly from middle and upper grades.There are still different opinions on the stage of directed forgetting,but the majority agree with the stage after middle grades.The thinking of children in the lower grades of primary school is dominated by intuitive action thinking and concrete image thinking,and the traditional research paradigm of directed forgetting may not be applicable to them.Based on the fact that children in lower grades are more sensitive to movement materials and are likely to show directed forgetting earlier,this study adopts the project method paradigm to investigate the characteristics and development trend of directed forgetting of primary school students' action memory through three experiments.In experiment 1,the effects of directed forgetting were studied under the conditions of Verbal task and Subject performed task,and the differences of directed forgetting in the two conditions were compared among the lower-grade students,so as to verify the ability of directed forgetting in the lower-grade students.On the basis of experiment one,experiment two has two subexperiments.They explore the development of directed forgetting under two conditions by studying students in three stages: lower,middle and upper,which mainly discusses the turning point of intentional forgetting ability under two different task conditions.This study has obtained the following conclusions :(1)There is a directed forgetting effect of item method in the lower grades of primary school,but it is only shown in the condition of verbal task,but not in the condition of Subject performed task;(2)From the lower grades of primary school to the upper grades of primary school,the ability of directed forgetting is constantly developed,and the middle and upper grades are in a relatively stable development stage;(3)There are age differences under different task conditions;(4)There is a turning point of directed forgetting under different task conditions.
