EEG dataset from a picture-word interference (PWI) picture-naming experiment conducted at the NeuroCognition Laboratory at San Diego State University. Participants named line drawings preceded by English distractor words that were semantically related, identical in name, or unrelated to the picture, while EEG and verbal responses were recorded. The dataset supports investigation of the neural correlates of lexical access and semantic interference during speech production.

Human EEG recordings from 20 participants viewing rapid sequences of overlaid oriented grating pairs while detecting a target grating of a specific orientation. Feature-based attention was manipulated by cueing one of two gratings by colour, and temporal expectation was manipulated by making stimulus onset timing predictable or unpredictable. The dataset supports investigation of the time-course of attention effects dissociated from temporal expectation and target-related processes.

EEG recordings from participants performing three near-threshold visual detection tasks that differed in cue information: a no-cue task, a noninformative cue task (50% validity), and an informative cue task (100% validity). The dataset was collected to study how prestimulus alpha-band activity relates to perception of near-threshold visual stimuli. It is shared in BIDS format.

EEG dataset investigating anticipatory neural differences between attention and expectation. The recordings were collected by a research group led by Maria Ruz and are organized in BIDS format. The dataset is mirrored on NEMAR from OpenNeuro (ds004502).

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.

EEG dataset of a visual oddball (P300) task from the PURSUE project, collected in 2017 and 2018 from participants at three primarily undergraduate institutions in Southern California, Massachusetts, and Virginia. The task design follows the ERP CORE paradigm, and the dataset includes participant demographic information such as race.

EEG dataset from a visual working memory experiment in which participants judged whether a probe grating was rotated clockwise or counterclockwise relative to a memorized orientation. Color cues either predicted a 90° segment of possible orientations or gave no information about orientation. The dataset supports investigation of how diffuse predictions stabilize and reshape neural codes during memory encoding.

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.

EEG recordings from 33 participants who each completed both a visual and an auditory surprise task, with task order counterbalanced. The dataset supports investigation of electrophysiological markers of surprise-induced failures of visual and auditory awareness. Data from participants excluded at various analysis stages are included up to the stage of processing they reached.

EEG recordings from participants viewing object and word stimuli presented in rapid serial streams at 5 Hz to the left visual field, the right visual field, or centrally. Participants performed an orthogonal red target detection task while stimuli were shown. The dataset supports investigation of the temporal dynamics of visual object coding within and across the cerebral hemispheres, particularly for objects in peripheral vision.
