An Experimental Study On Training Working Memory With N-Back Task

The human brain has great plasticity.This plasticity can be achieved in many ways.More and more attention has been paid to changing people's abilities through training.In addition,the study of working memory has gradually shifted from the initial stage of concept presentation to the discussion of the internal mechanism of working memory and the relationship between working memory and other cognitive functions(such as intelligence,selective attention,executive function and psychological theory).However,the current more important research trend is to explore the paradigm of working memory,which is applied to cognitive training,and form the field of working memory training.Research method and purpose:in this study,the Dual N-Back task will change from a working memory paradigm to a training task.The core of this study is to test the improvement of the subjects' ability after training for about one month.Ability here refers to the effect of transfer,which is measured by the breadth of working memory span tasks and specific intelligence test scores.The results showed that the visual spatial span of the trained subjects were not improved compared with those of the untrained and untrained subjects.But the intelligence test scores were improved.In a word,working memory can indeed improve the ability of measurement.Research conclusion: the human brain does have plasticity and can be partially controlled by humans.The correlation between N-Back task and working memory span task was low.
