Abstract
Thajus Asirvatham raises important points. The first concern is about an outcome measurement used in the study to assess executive function. As he indicated, the Trail Making Test Part B (TMT-B) is one of conventional neuropsychological assessments, focusing on evaluating executive function itself rather than functionally assessing it. Nevertheless, the reason why the TMT-B was used is that one of the purposes of the study was to measure cerebral blood flow during executive functioning. The Korean version of the Executive Function Performance Test (EFPT-K) is a top-down performance assessment [3]. Since the EFPT-K requires participants to complete some tasks, measurements of cerebral blood flow using a functional near-infrared spectroscopy during the tasks might be inappropriate due to noise [4].
