The central issue of this paper is to review the possible relationships between the constructs of critical thinking and executive functions. To do this, we first analyse the essential components of critical thinking from a psychological and neurological point of view. Second, we examine the scope of the cognitive and neurological nature of executive functions. Third, we propose a model for comparing or mapping between the most important processes of both constructs. Fourth, we offer some conclusions on the relational path between the two concepts based on the studies reviewed and suggest possible lines of investigation that will undoubtedly facilitate the understanding of shared features and key differences between critical thinking and executive functions.
