EEG dataset from 53 participants (N=39 used for stimulus-locked ERP analyses) performing a bilateral change-detection task to study how perceptual grouping by color repetition affects visual working memory (VWM). The design isolates neural correlates of individuation encoding, maintenance, initial comparison, percept-memory comparison, and late decision-making using the N2pc, CDA, N2, and FN400 ERP components. Conditions varied the number of items, color repetition, and spatial proximity of repeated items.

This dataset contains simultaneous EEG and facial EMG recordings examining symmetry perception and associated affective responses. Participants viewed visual patterns and, after stimulus offset, reported whether each pattern was regular (symmetric) or random. It supports investigation of neural and psychophysiological correlates of the processing of visual symmetry.

This dataset contains 124-channel EEG recordings from 13 participants who imagined and perceived stimuli from three modalities: visual pictorial, visual orthographic, and auditory. Stimuli came from three semantically dissimilar categories (guitar, flower, penguin). Raw, pre-processed, and epoched versions of the data are provided to support research on semantic decoding from EEG.

A collection of electroencephalography (EEG) recordings from 15 students (8 male, 7 female, aged 21-23) performing essay-writing tasks. The task was designed to assess cognitive conditions such as creativity, memory, and critical thinking under different generative AI interaction conditions. The dataset supports studies of brain connectivity during student learning processes with Gen-AI.

A motor imagery EEG dataset from 54 healthy participants performing binary left/right hand grasping imagery across two sessions on different days. Recordings were made with 62 EEG channels plus 4 EMG channels at 1000 Hz. The data belong to a larger multi-paradigm BCI collection (MI, ERP, SSVEP) used to investigate BCI illiteracy and variation in decoding performance across subjects and sessions.

EEG dataset recorded while participants performed a visual working memory task in virtual reality using a head-mounted display. Memory items (a bowl, cup, plate and teapot) were cued by either a virtual avatar or a stick, with cues that were spatially valid or invalid. Participants were probed on item location and item status. The dataset includes raw and processed EEG, behavioral data, event codes and analysis code.

EEG dataset from 146 participants (98 with Parkinson's disease and 48 controls) performing a cross-modal oddball task collected between 2017 and 2021. Each trial presented simultaneous visual and auditory pre-cues, either standard or oddball, followed by a directional arrow GO cue requiring a response. The dataset supports investigation of midfrontal neural activity and cognitive dysfunction in Parkinson's disease.

EEG dataset from Experiment 1 of a study on whether capacity for movement is an organisational principle in visual object representations. Twenty-four participants viewed images of moving or non-moving, natural or artificial objects, completing a time-pressured aliveness classification task and a passive RSVP viewing task with a fixation-colour detection response. The release includes raw BrainVision EEG, preprocessed EEGLAB and CoSMoMVPA data, decoding results, analysis code, and 400 CC0 stimulus images.

EEG recordings from 23 participants performing a passive viewing task with partially occluded and subsequently uncovered scenes containing game pieces on a game board. Conditions varied the number of initially visible pieces (4 or 32) and the number of pieces revealed after the occluder was removed (0 to 32). The dataset supports investigation of neural responses to object numerosity in occluded and uncovered visual scenes.
