People with high self-control have increased performance and neural efficiency in temporally uncertain vigilance tasks
Proceedings of the Human Factors and Ergonomics Society ... Annual Meeting(2023)
摘要
The vigilance decrement, the decline in behavioral adaptability seen after sustaining attention over time, has been a monumental problem in the applied sciences for the past 70 years. Trait selfcontrol is a measure of the general capability to regulate one’s own cognitive resources. In the present study, participants performed a 24-minute vigilance task that was either synchronous (temporally regular) or asynchronous (temporally irregular). We empirically investigated the effects of self-control, watch period, and event asynchrony on performance and neural resource expenditure through functional near-infrared spectroscopy (fNIRS). Here we demonstrate that trait self-control indexes an operator’s capability to prevent making false alarms. Additionally, we elaborate on the functional role of self-control in optimizing right parietal resource usage and subsequently, resilience against the vigilance decrement. Finally, we discuss theoretical and practical implications for Neuroergonomics practitioners.
