N-Back based working memory contents to improve cognitive function

Abstract

Cognitive function damage can cause various problems such as work performance requiring concentration and independent daily life as well as social life which requires interpersonal relationship. In the cognitive function area, the working memory is a function to recreate only the information necessary for the external information and the memory of the past, and utilize it appropriately for the daily life behavior, thus working memory training helps improve the cognitive function of the elderly or children with weakened cognitive function. This paper employed an n-back method, one of the frequently mentioned methods in working memory training studies recently, as the basic program of research and established working memory training contents. This content is designed not only to select the difficulty level and four basic n-back training methods by visual (location, color) or auditory (alphabet, number) stimulation, but also to make training by creating n-back based functional game which can induce user's interest.
