Changes in efficiency and involvement based on adaptive target find and scan performance and fNIRS measures from channels 2, 7, and 12 per Group and Session. The four quadrants generated by the efficiency (E) = 0 and involvement (I) = 0 lines represent combination of high efficiency (HE) or low efficiency (LE) and high involvement (HI) or low involvement (LI). Circles on the graphs reflect mean, while error bars represent standard deviation
