Kurzfassung
Flying an aircraft puts high cognitive demands on the pilot. If the demands exceed the pilot’s cognitive resources, this may lead to errors and severe, if not fatal, consequences. A continuous and objective assessment of mental workload could indicate when to provide assistance to the pilots, even before performance declines. A viable candidate for such an assessment is functional near-infrared spectroscopy (fNIRS). In the present study, we used fNIRS to assess mental workload changes in a flight task. 35 participants completed a 40-minute simulated flight with an incorporated adapted n-back task: The participants had to perform course corrections in accordance with the n-back task in four difficulty levels (0- to 3-back). We assessed n-back performance and oxygenation changes in the dorsolateral prefrontal cortex. Our results show that performance in the n-back task was stable between the 0- and 1-back conditions, then decreased linearly with each higher n-back level. fNIRS data showed a decrease in deoxygenated hemoglobin (Hbr) with increasing n-back level. More precisely, using Hbr, we could discriminate all n-back levels apart from the two highest. We conclude that while fNIRS was not sensitive to higher levels of demand where performance already showed a steady decline, it was indeed sensitive even to slight elevations of cognitive demand that did not yet impair performance. In consequence, fNIRS is a promising method for mental workload assessment and its application in the aviation domain.
