The BCIT Mind Wandering dataset comprises electroencephalography (EEG), eye tracking, and vehicle performance data collected during prolonged simulated driving tasks designed to assess fatigue-related biomarkers and driver performance under different cognitive load conditions. Participants performed 30-minute driving scenarios with three types of background audio (task-relevant, non-task-relevant, and internal focus) while responding to vigilance tasks and managing vehicle perturbations. This dataset extends prior driving research by incorporating extended time-on-task measurements and novel audio manipulations to investigate the relationship between brain activity, mind wandering, and driving performance.

The BCIT Baseline Driving dataset comprises extended time-on-task EEG recordings from subjects performing a 60-minute simulated driving task across three research sites. Designed to assess fatigue-related performance degradation through novel EEG biomarkers, the study collected high-density EEG data (64 or 256 channels) synchronized with objective driving performance metrics including steering corrections, lane position, and reaction times to vehicle perturbations. This dataset serves as a foundational resource for investigating the neurophysiological correlates of driver fatigue and developing predictive algorithms for fatigue detection.

The BCIT Basic Guard Duty dataset comprises EEG, eye-tracking, and behavioral data collected during a sustained vigilance task in which participants verified replica identification cards against reference images. Subjects performed ten 5-minute blocks of the guard duty task with varying ID presentation rates (1-25 per minute) while seated in a driving simulator. This dataset provides multimodal neurophysiological and performance measures of cognitive fatigue and attention during a realistic security screening task.

The BCIT Calibration Driving dataset comprises electroencephalography (EEG) recordings collected during a standardized 15-minute driving simulator task designed to establish baseline, non-fatigued performance metrics. Participants controlled vehicle steering on a simulated straight road while responding to lateral perturbations, with data collected across three sites: Army Research Laboratory (Aberdeen, MD), Teledyne Corporation (Durham, NC), and Science Applications International Corporation (Louisville, CO), using 64- or 256-channel Biosemi EEG systems. This calibration dataset serves as the foundational component for fatigue-related driver performance prediction algorithms within the broader BCIT neuroimaging program.

This dataset comprises scalp EEG recordings from 23 healthy young adults performing a modified Sternberg working memory task. Participants selectively memorized sequences of letters while ignoring distractors, maintained them during a delay period, and responded to probe letters via button press. The study investigates source-resolved EEG brain dynamics underlying working memory encoding, maintenance, and retrieval processes, with auditory feedback provided for response accuracy.

The Advanced Guard Duty dataset comprises EEG, eye tracking, and behavioral data collected during a sustained vigilance task involving verification of replica identification cards. Subjects performed a 50-minute guard duty task organized into ten 5-minute blocks with varying ID presentation rates (1-25 per minute) and verification criteria. This dataset provides neurophysiological and performance measures of cognitive workload and fatigue in a realistic security screening scenario.

The BCIT Auditory Cueing dataset comprises EEG, eye-tracking, and vehicle performance data collected during a prolonged simulated driving task designed to assess driver fatigue and cognitive state. Subjects performed two 45-minute driving conditions with either random or predictive auditory cues preceding lateral vehicle perturbations, while continuous measurements of steering behavior, reaction times, and subjective fatigue scales were recorded. This dataset extends prior driving research by examining the relationship between neural biomarkers and fatigue-related performance decrements in a controlled, high-frequency perturbation environment.
