Study on intuition by EEG phase synchronization relevant to proficiency during factorization

Abstract

Little is revealed on the mechanisms underlying cognitive expertise such as perception and intuitive understanding.In this paper,using the factorization task as a mental arithmetic task,we focus on the brain activity in experts relevant to intuitive understanding of equation patterns.We record response times to get the solution to equations and EEG signals in perception of equations.According to quick response times,we evaluate intuitive understanding of equation patterns in factorization.We assess each subject's proficiency in factorization with a paper test.We examine if increase of EEG phase synchronization is concerned with only expert intuitive understanding.As the result of the study,a relevance between each subject's proficiency in factorization and EEG phase synchronization in intuitive understanding of equation patterns was observed.
