    "title": "Task Resolution Time Estimation through Cognitive Load: An EEG Study of Chess Players",
    "subtitle": null,
    "abstract": "Assessing attention is essential for optimizing performance. This study identifies a single-channel EEG biomarker based on cognitive load to estimate Task Resolution Time (TRT). Thirty-seven chess players were recorded with an 8-channel EEG headset while solving chess problems under two conditions: distracting noise (65 dB) and ambient noise (40 dB). Participants were grouped by chess expertise (ELO rating), and cognitive load was measured via theta (4-8 Hz) power on the C4 channel. EEG signals underwent preprocessing with a bandpass filter, Artifact Subspace Reconstruction (ASR), and Independent Component Analysis (ICA). Power estimation (Welch) was normalized to a resting 30-second Eyes Open (EO) period. TRT analysis indicated shorter engagement times and slightly lower performance in novices under noise, while experts remained relatively stable, possibly due to better cognitive resilience. This biomarker could be further integrated into portable EEG systems for real-time neurofeedback in educational and workplace settings.",
