Neurofeedback Training for Cognitive Optimization: Effects on Performance and Workload in a Simulation Task

SessionCEDM2: Attention Management in Dynamic Environments

DescriptionThis research investigates the impact of Focus Index (FI)-based neurofeedback (NF) training on the performance and cognitive workload during high-stakes decision-making search and shoot tasks. Neurofeedback has been proven to enhance attention and decrease stress by allowing self-regulation of brain activity. Its efficacy in dynamic high-pressure situations, however, has not been explored. In the experiment conducted for this research, forty volunteers were divided into two groups at random: an NF group and a control group. The NF group provided real-time visual feedback of attentional engagement during training sessions. Both groups were tested pre- and post-training on search and shoot tasks, with performance measures of number of enemies defeated, bullets fired, and survival time. Subjective workload was measured using the NASA-TLX, and data were analysed using mixed-design ANOVAs. The NF group showed significantly larger performance improvements and lower mental and effort-related workload ratings than the control group. EEG-based feedback also showed enhanced attentional self-regulation after NF training. These findings indicate that FI-based NF training can improve performance and cognitive efficiency under time pressure. This method has strong potential as a neuroadaptive tool for enhancing focus, decision-making, and workload management in military and other high-stress operational environments.
