fNIRS examination of mental workload changes during N-back tasks (Conference Presentation)

Paper Abstract

Working memory (WM) is part of the short-term memory storage in human brain. N-back is a WM task to assess mental workload on the prefrontal cortex (PFC). In this work, we studied how mental workload changes in an N-back task over the length of the experiment. We focused on two task levels of two- and three-back. Examining both hemodynamics and behavioral data (correct answers), we found a significant difference between 2-back and 3-back tasks and a significant difference between the beginning and end of the 3-back task.
