Data sharing

• Files in the data directory contain continuous and epoched single trial EEG data kept under project personnel control and may be shared only under IRB approved protocol modification and data sharing agreements.

• Files in the other directories contain stimuli, data processing routines, and deidentified summary measures that may be viewed without restriction according to the terms of the licences.

Experimental Stimuli

The EEG stimuli are scraped from the corresponding ERPSS scenario files

Normative data

• The single trial responses are scraped from lightly reformatted copies of KAD's original Excel worksheets and saved as rows x columns text table.

• The response counts, proportions, and related measures are computed from the tabular text and stored as a list of YAML maps, one per experimental item.

EEG experiment HDF5 data files

• udck19 Experiment 1 mkdig/eeg_1_arquant are converted from copies of binary files in ~kadelong/Exps/arquant

• udck19 Experiment 2: mkdig/eeg_2_arcadj are converted from copies of files in ~kadelong/Exps/arcadj

• udck19 Experiment 3: mkdig/eeg_3_yantana are converted from copies of files in kadelong/Exps/Yantana

Raw and single trial epochs

All raw and single trial epochs are time-locked to the ARTICLE

This means the noun is the following word in all eeg_1 (arquant) and eeg_3 (yantana) epochs.

In eeg_2 (arcadj) the noun is the following word for trials with where noun event codes end in 1, 2, 3, 4, 5 and have item_id of the form

iNNN_2_a__NA_noun
iNNN_2_an_NA_noun

The noun is two-words downstream for the article+adjective+noun trials where noun event codes end in 7, 8 and item_id is of the form
