Words ranged from 1 - 14 letters long and sentences ranged from 6 – 12 words long. Words were presented with a height of 80 and width of 40, the fovea visual angle ranged from .75 – 6.21 degrees, with the largest peripheral visual angle of 15.18 degrees. Conditions consisted of 30 subject-verb agreement violations, 30 semantic violations, 30 double (subject-verb agreement + semantic) violations, 30 word-order violations, and 60 control (correct) sentences. Sentences were presented in an RSVP with flankers design, with three words presented at a time in the middle of the screen, each word appeared in the middle of the screen for a duration of 400ms before appearing to slide to the right and be replaced by the next word in the sentence. There was no ISI for this task to eliminate the words from appearing to flash at the participant instead of sliding.\u0000\u0000","bids_version":"1.8.0","sessions_count":null,"publish_date":null,"embedding_dirty":0,"license_tier":"public","zarr_status":null,"zarr_converted_at":null,"zarr_store_count":null,"zarr_index_etag":null,"zarr_source_commit":null,"archive_status":"ready","archive_size":5836473228,"archive_retry_count":0,"records_status":"ready","archive_skip_reason":null,"zarr_errors":null,"zarr_failure_count":null,"zarr_deterministic":null,"zarr_failed_at":null,"num_dataset_citations":0,"num_datapaper_citations":0,"n_channels":32,"electrode_system":"10-10","has_hed":0,"hed_version":"8.1.0","is_exemplar":0,"bytes_present":6670898551,"data_complete":1,"withdrawn_at":null,"withdrawn_reason":null,"archive_complete":1,"archive_absent_files":0,"archive_declared_files":331,"zarr_pool_breaks":null,"total_recording_duration":null,"recording_duration_min":null,"recording_duration_max":null,"recording_count":null,"recordings_unavailable":null,"recordings_measured":null,"channel_count_min":null,"channel_count_max":null,"sampling_frequency":500,"power_line_frequency":60,"eeg_reference":"Left Mastoid","placement_scheme":"custom","sweep_stamps":"{\"enrichment_updated_at\":\"2026-09-08 21:09:40\",\"metadata_updated_at\":\"2026-09-08 21:09:53\",\"records_checked_at\":\"2026-09-08 21:10:54\",\"archive_checked_at\":\"2026-09-08 21:14:18\"}","participants":64,"num_citations":0,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"nemarAdmin","owner_github":"nemarAdmin","file_size_formatted":"6.22 GB","zarr_data_failures":null,"zarr_index_url":null,"attestation_deposit_type":null,"attestation_key_status":null,"attestation_deidentified":null,"attestation_no_duplicate":null,"attestation_upstream_source":null,"attestation_accepted_at":null}}
