EEG dataset from 19 participants performing a visual P300 speller-like paradigm to assess how visual stimulus properties affect evoked responses and classification accuracy. Each participant completed three sessions with conditions varying the number of stimuli (4 to 9) and the flash type (standard flash versus a superimposed yellow smiling cartoon face). Recordings comprise 382 files from eight electrodes sampled at 256 Hz, with markers encoding trial phases and activated symbols.
An EEG dataset of a perception and mental imagery task. Participants viewed an image for 6 seconds in response to an auditory prompt, then closed their eyes and imagined the same image for 6 seconds. A further prompt sound started the next trial. The recordings can be used to study neural correlates of visual perception versus imagery and to develop decoding methods.

EEG recordings from twenty participants who learned three temporal intervals (short, medium, long). Two randomly interleaved subtasks were used: a Production task, in which participants produced a target interval, and a Perception task, in which they judged whether a computer-generated interval was correct. Visual feedback (checkmark or x) followed both tasks. The dataset supports investigation of temporal scaling of human scalp-recorded potentials.
EEG dataset investigating the neural time course of spontaneous face perception, including face pareidolia. Participants viewed 300 images of human faces, illusory faces, and matched non-face objects presented centrally at 3.75 Hz while performing an orthogonal target detection task. The study also involved behavioural tasks (odd-one-out dissimilarity, face-likeness ratings, and face/object categorisation) using the same stimuli.
