EEG recordings from 25 college-age participants performing a probabilistic reinforcement learning task with affective feedback (Experiment 2). The dataset was collected to examine how the Reward Positivity (RewP) event-related potential is sensitive to affective liking of feedback stimuli. Data were acquired circa 2019 at the University of New Mexico.

EEG recordings from 13 healthy participants performing a copy-spelling task with a visual 6x7 matrix ERP speller. The speller was designed for learning from label proportions (LLP), an unsupervised, calibrationless classification approach for ERP-based brain-computer interfaces. Two stimulus sequences with different target/non-target ratios allowed LLP to reconstruct mean target and non-target responses without labeled data. In the original online study, 84.5% of characters were spelled correctly on average without prior calibration.

Raw 64-channel EEG, electrocardiography, photoplethysmography, pupillometry and behavioral data from 86 participants during 4 minutes of eyes-closed rest and a digit span serial recall task. Participants memorized or passively listened to auditory digit sequences of 5, 9, or 13 items. The dataset supports work on cognitive load discrimination, event-related and oscillatory dynamics during encoding and maintenance, and links between working memory, central and peripheral physiology.

EEG recordings from participants receiving laser stimuli of calibrated intensity to evoke pain. After individual calibration to the energy level yielding an average rating of 7, each participant received 10 laser stimulations and rated pain intensity and unpleasantness on a 0-10 numeric rating scale. The dataset supports research on pain perception and related neural responses.

Multimodal dataset of 29 participants watching six educational videos under two conditions: an attentive session with intentional learning and subsequent factual questions, and a distracted session with a silent backward-counting task. Recordings include EEG, EOG, ECG, gaze, pupil size, blinks, saccades and head position. Questionnaires (stimulus knowledge questions and the ASRS adult ADHD checklist) are provided. The dataset supports research on attention and learning from video.
