Vaibhav Tyagi has published research on cognitive load in binumeracy. The title of the original research paper is "Notational usage modulates attention networks in binumerates".
“Hindu-Arabic numbers (used in English) share a set of common features with Hindu-Nagari numbers (used in Hindi). This study investigated the effect of differential usage of these number notations on the brain and found an increased cognitive load when processing less used Hindu-Nagari numbers.”
