EEG dataset from forty participants who read an interactive story containing decision points. On each trial participants saw an item, made a yes/no decision, and received correct or incorrect feedback. The design compares a narrative condition, with story context at item onset and after feedback, against a nonnarrative condition with no such context. It is intended for studying how narrative context affects reward and feedback processing.

This dataset contains behavioral events and intracranial EEG recordings from a delayed free recall task in which participants studied visually presented word lists, solved arithmetic distractor problems, and then freely recalled the words. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. Monopolar and bipolar recordings are provided with subject-specific electrode montages, MNI/Talairach coordinates, and brain region annotations.

This dataset contains EEG/ERP recordings from a randomized controlled trial comparing forward span training, backward span training, and no-intervention control groups on working memory. Recordings were collected at pre-, mid-, and post-test while participants performed a distractor version of the change detection task, and behavioral data were collected from additional change detection and suppress tasks. The data support analyses of working memory maintenance and interference control, indexed by Kmax and contralateral delay activity (CDA).

This dataset contains EEG recordings from 34 participants (one session each) who viewed 242 object images, 121 challenge and 121 control images, selected from comparisons between human behavioural performance and AlexNet. The study examines adaptive recruitment of cortex-wide recurrent processing during visual object recognition. The derivatives folder contains outputs of the decoding analyses, including time-resolved decoding accuracy matrices for object identity (.npz).

This dataset contains 64-channel EEG recordings and behavioural ratings from participants who read and evaluated 210 short English-language texts: 70 Haiku, 70 Senryu, and 70 non-poetic control texts. Each text was rated on aesthetic appeal, vivid imagery, being moved, originality, and creativity. This first of two BIDS datasets includes 47 participants whose recordings passed technical validation. Psychometric questionnaire data and resting-state EEG are also provided.
