{"schema_version":"0.4.0","doc_type":"dataset","dataset_id":"on007955","name":"EEG and autonomic responses during emotional word association","description":"This dataset comprises synchronized electroencephalographic (EEG), autonomic physiological, and behavioral recordings acquired during an emotional word association task. Participants performed a lexical task involving fear-related concepts, selecting or generating words in response to prompts while neural activity, autonomic responses (electrodermal activity, blood volume pulse, interbeat interval, and skin temperature), and behavioral events were recorded. The dataset includes 8-channel EEG data sampled at 250 Hz alongside physiological signals from an Empatica E4 wristband, with semantic similarity measures between consecutive word responses. This is the enriched version of OpenNeuro dataset ds007955 with additional analysis and documentation. Note: Physiological data for participant 7 are unavailable due to a data acquisition error with the Empatica E4 recording system; EEG and behavioral data remain available for this participant.","source":"nemar","recording_modality":["EEG"],"bids_version":null,"license":"CC0","authors":[{"name":"Manuel Cebral-Loureda","name_type":"Personal","orcid":"0000-0001-6359-2427","affiliations":[{"name":"Tecnologico de Monterrey, School of Humanities and Education","identifier":null,"scheme":null}]}],"keywords":[{"term":"EEG"},{"term":"emotion recognition"},{"term":"word association"},{"term":"Autonomic Nervous System","subject_scheme":"MeSH","value_uri":"http://id.nlm.nih.gov/mesh/D001341"},{"term":"electrodermal activity"},{"term":"physiological signals"},{"term":"fear-related concepts"},{"term":"semantic similarity"},{"term":"lexical task"},{"term":"OpenBCI"},{"term":"Empatica E4"},{"term":"Emotions","subject_scheme":"MeSH","value_uri":"http://id.nlm.nih.gov/mesh/D004644"},{"term":"Fear","subject_scheme":"MeSH","value_uri":"http://id.nlm.nih.gov/mesh/D005239"}],"related_identifiers":[{"identifier":"https://github.com/nemarDatasets/on007955","identifier_type":"URL","relation_type":"IsDescribedBy"},{"identifier":"https://nemar.org/dataexplorer/detail?dataset_id=on007955","identifier_type":"URL","relation_type":"IsDescribedBy"},{"identifier":"10.3389/fnhum.2024.1319574","identifier_type":"DOI","relation_type":"IsReferencedBy"},{"identifier":"10.1080/23311983.2025.2591387","identifier_type":"DOI","relation_type":"IsReferencedBy"},{"identifier":"10.3389/fnhum.2026.1692599","identifier_type":"DOI","relation_type":"IsReferencedBy"},{"identifier":"10.18112/openneuro.ds007955.v1.0.0","identifier_type":"DOI","relation_type":"IsDerivedFrom"}],"contributors":[],"dates":[],"rights":[{"rights":"CC0","rights_uri":null,"rights_identifier":"CC0","rights_identifier_scheme":"SPDX"}],"language":null,"funding":[{"funder_name":"SECIHTI","award_number":"CF-2023-G-583","award_title":"Ciencia de Frontera 2023","funder_identifier":null,"funder_identifier_type":null,"award_uri":null}],"tasks":["wordassociation"],"datatypes":["eeg"],"sessions":[],"sessions_count":null,"demographics":{"subjects_count":9,"age_min":null,"age_max":null},"data_summary":{"total_files":94,"size_bytes":30811181,"size_human":"29.4 MB","recording_count":9,"recordings_unavailable":0,"total_recording_duration":1619.9560000000001,"recording_duration_range":{"min":152.112,"max":241.76},"channel_count_range":{"min":8,"max":8}},"signal_defaults":{"sampling_frequency":250,"power_line_frequency":60,"reference":"Linked earlobes (A1/A2)","recording_type":null,"channel_system":"10-20","placement_scheme":null},"provenance":{"latest_snapshot":"v1.0.0","publish_date":"2026-06-17 13:34:51"},"external_links":{"dataset_doi":"10.82901/nemar.on007955","github_url":"https://github.com/nemarDatasets/on007955"},"extensions":{"nemar":{"versions":[{"version":"v1.0.0","doi":"10.82901/nemar.on007955.v1.0.0","created_at":"2026-06-17 13:34:51","manifest_url":"/on007955/v1.0.0/manifest.json"}],"bids_index":{"version":"v1.0.0","subjects":{"sub-01":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-02":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-03":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-04":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-05":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-06":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-07":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-08":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}},"sub-09":{"sessions":[],"modalities":{"eeg":{"tasks":{"wordassociation":{"runs":[]}}}}}}},"pipeline_stage":"enriched","data_complete":null,"bytes_present":null,"recordings_measured":9}}}
