Memory Characteristics And Educational Recommendations Of Primary School Students With Different Body Mass Index In Middle And High Grades

A large number of studies have shown that most obese children have varying degrees of psychological problems,which are often reflected in weak self-recognition,low self-esteem,moodiness,and a solitary or extreme personality.Obese children are more likely to be ridiculed by their peers for their obese physique.They will pay more attention to others' perceptions and perceptions of their own,and are sensitive to mood swings.Obesity problems will affect children's positive emotions and cause children to exert a lot of psychological pressure.Serious emotional abnormalities,in turn,act on their physiology,causing them to get fatter and fatter.Obese children's working memory load,hand-brain coordination ability,and problem understanding ability are lower than normal weight children.The cognitive ability of human beings is one of the core issues of psychological research.Memory is the foundation for advanced psychological activities and the basic skills for human life,learning and work.Memories are also important and necessary skills for elementary school students who have been in school for a long time.It can be said that memory is an indispensable factor in learning activities.However,there are few studies on the impact of BMI index on memory,and research on implicit memory has a hot trend in memory research.Therefore,researchers choose implicit and explicit memory as the entry point.This experiment is a two-factor two-level mixing experiment.The independent variables include: picture type(high calorie type/neutral),BMI index(high/normal).The dependent variable is the contribution rate of the subject's automatic extraction and consciousness extraction to the task,that is,the implicit memory score and the explicit memory score.The process of this experiment is completed through two learning stages and one testing stage.In the implicit memory results,consider the P<0.05 of the independent variable picture type(high calorie/neutral),and the main effect of the picture type is obvious.In the results of explicit memory scores,the P<0.05 of the independent variable picture type(high calorie/neutral)was considered significant.In the comparison of picture type factors for the average scores of pupils' implicit and explicit memory,it was learned that the two groups of implicit memory and explicit memory responded to the experimental test of high-calorie pictures,and the average memory level was high.The explicit memory performance,implicit memory,and scores of the subjects on the neutral pictures showed that the high-calorie images had more influence on the subjects' implicit and explicit memory than the neutral images.In a word,this study has reached the following conclusions: 1.The number of obese children is large and the proportion of obese children is about 21.98%.2.For memories of food cues,obese children showed better explicit memory scores than normal-weight children.However,there is no significant difference in implicit memory.3.The difference in the nature of experimental materials affects children's explicit and implicit memory performance.Children have better memories of high-calorie pictures.
