data_validity

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.
