This dataset contains EEG, physiological (ECG, PPG, respiration) and behavioural recordings from 103 healthy adults aged 21-45, collected in 2022-2023 as part of a larger study. Participants completed an 8-minute eyes-closed resting state, followed by the Illusion Game. In this task they made perceptual judgements about the Ebbinghaus, Müller-Lyer and Vertical-Horizontal illusions, with task difficulty and illusion strength varied. The data are intended for investigating individual sensitivity to visual illusions as a general factor.

Preprocessed stereotactic EEG (SEEG) high-gamma power (50-100 Hz) from 16 patients with pharmaco-resistant epilepsy performing a probabilistic instrumental learning task with reward and punishment conditions. Data cover 248 bipolar derivations in the anterior insula, dorsolateral prefrontal cortex, lateral orbitofrontal cortex and ventromedial prefrontal cortex, time-locked to outcome. The derivative release supports information-theoretic analyses showing dissociable reward and punishment subsystems in the human frontal cortex.

EEG recordings from participants performing two reversal learning tasks that differ in reinforcer type: monetary reward versus avoidance of an aversive loud white noise burst. In the reward task, positive feedback meant a gain of 10 cents and negative feedback meant no gain. In the punishment task, positive feedback meant the noise burst was successfully avoided and negative feedback meant the noise was delivered. Noise intensity was titrated per participant to match the motivational value of the 10 cent reward.

Simultaneous EEG-fMRI dataset from 18 participants who played two games (a face game and a maze game) during wakefulness in a 3T MRI scanner. One game was randomly assigned to be won (reward) and the other lost (no reward). Participants then slept in the scanner with 64-channel EEG for 1-2 hours. A classifier trained on game-session data was applied to sleep-session fMRI to examine reward-biased spontaneous neural reactivation, and memory for both tasks was tested the next day.

EEG recordings from 54 community participants classified as light or heavy drinkers performing an affective-state reinforcement learning task involving alcohol imagery. The dataset supports investigation of reward-related neural responses, such as the reward positivity, in relation to drinking behavior. Data were collected between 2019 and 2021.

EEG recordings from fourteen healthy participants performing a covert spatial attention task across three sessions. The study tested real-time feedback of alpha power lateralization (α-LI) versus sham feedback in a single-blinded crossover design. It examined whether such neurofeedback leads to behavioral improvements in attention.

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.

This dataset contains EEG, physiological, and behavioural recordings collected in 2020 from 44 healthy adults aged 21-40. It includes eyes-closed resting-state recordings and two tasks: a spontaneous deception task (a gambling game with self-reported dice-roll predictions) and a cognitive control task battery. The battery covers processing speed, response selection, response inhibition, and conflict resolution.

EEG recordings from 25 college-aged participants performing a probabilistic reinforcement learning task with affective feedback. Data were collected around 2018 in the CRCL at the University of New Mexico to examine how the Reward Positivity is influenced by affective liking of feedback. Additional scripts are included to clarify stimulus triggers and support secondary analyses.
