464,798,300 rows (estimated) across 24 tables. Row counts are fast estimates from the query planner statistics.

Table	Rows (est.)	Description
affective_task_event	14,586	Events from the individual and team affective tasks.
audio_vocalics	0	OpenSMILE acoustic features extracted from each participant's microphone audio during the Minecraft missions; each row is one analysis frame. Beyond the identifying columns below, the table has one column per OpenSMILE low-level descriptor (LLD) from the ComParE feature set (e.g. `f0final_sma`, `jitterlocal_sma`, `shimmerlocal_sma`, and the `audspec_rfilt_sma[]` and `mfcc_sma[]` families) together with their first-order delta (`*_de`) coefficients.
data_validity	3,060	Table with information about which participants were involved in the tasks, and whether the data from the EEG, fNIRS, and eye tracking modalities are valid. In most cases, when an experimenter stepped in to replace a participant (e.g., for a no-show participant), they did not wear fNIRS/EEG devices, and in some cases, they did not wear the eye tracker either. Not all groups completed all the tasks, and for some tasks, the data is missing. In cases such as these, the table simply omits rows for which we do not have data.
eeg_device	120	Table with a mapping between station and EEG device id used in each experiment.
eeg_raw	320,700,928	Table with raw EEG data.
eeg_sync	0	Table with EEG data synchronized to a main clock with fixed frequency. The start and end timestamps of the main clock spans across all the tasks in the experiment. Each remaining column is one EEG electrode, named for its 10-20 montage position (see the documentation for the electrode montage figure).
ekg_sync	0	Table with EKG data synchronized to a main clock with fixed frequency. The start and end timestamps of the main clock spans across all the tasks in the experiment.
finger_tapping_task_observation	99,875	Observations from the baseline finger-tapping task.
fnirs_raw	6,837,054	Table with raw fNIRS data.
fnirs_sync	0	Table with fNIRS data synchronized to a main clock with fixed frequency. The start and end timestamps of the main clock spans across all the tasks in the experiment. Each signal column is one source-detector (S#-D#) channel; `_hbo` columns are oxyhemoglobin and `_hbr` columns deoxyhemoglobin concentrations (see the documentation for the optode montage figure).
gaze_raw	129,968,696	Table with raw Gaze data.
group_session	40	Table with group session IDs.
gsr_sync	0	Table with GSR data synchronized to a main clock with fixed frequency. The start and end timestamps of the main clock spans across all the tasks in the experiment.
minecraft_mission	51	Metadata about the Minecraft missions.
minecraft_testbed_message	5,856,114	Messages sent over the testbed's message bus during missions.
modality	3	Modalities for physiological data.
participant	114	Table with participant IDs.
ping_pong_competitive_task_observation	647,242	Observations from the competitive ping-pong tasks.
ping_pong_cooperative_task_observation	323,806	Observations from the cooperative ping-pong tasks.
post_game_survey	96	Each participant's responses to the REDCap "Post Game Survey", administered at the end of the group session. Items capture emotions felt during the game, impressions of the AI agent and of the other team members, and teamwork/decision-making ratings. Numeric items use the small Likert/slider scales noted per column.
rest_state_task	0	Start and stop times of the baseline rest-state task, during which participants sat quietly while physiological signals were recorded.
screen_capture	346,502	Table with screen capture data.
station	4	During the group session, each participant is seated at one of four iMacs, labeled 'lion', 'tiger', 'leopard', and 'cheetah'. The 'cheetah' station is only used in the competitive ping pong task, when an experimenter steps in to play against the participant seated at the 'leopard' station.
task	9	The different tasks that take place during a group session.
