Dataset for the EEG study of colocation in sighted and blind infants

Behavioural data

data_gori_colocationEEG_behav_unisensory.txt.

Orienting responses and reaction times (RT) are reported, based on the scoring of two independent naive raters,  for each trial of each subject(participant_id), group (SVI/S), posture (Uncrossed/Crossed), and sensory condition (Tactile only, Auditory only).

Trial is the trial number, condition is the sensory condition, audio and tactile respectively refer to the side of the stimulated hand, response_status reports if the response is defined or undefined, trigger is the trigger denoting the stimulation in the EEG recording, response modality reports if the modality used by subjects to respond/not to respond to stimuli (hand, eye, both hands, no motion), group is if the subject was a sighted (S) or a severely visually impaired (SVI) infant, age is the age expressed in months, RT_rater1, RT_rater 2 and RT are respectively the RT assigned by the two raters and the merge of the two estimations (for RTs, the mean), the same organization for response_side, and for response_modality (for those variables, when the estimation of the two raters did not agree, the merged classification was set to unknown, that is uncertain/undefined).

EEG data

EEG data of the study in BIDS format.

conditions are coded as follows: posture (u=uncrossed, c= crossed), hand stimulated with audio (l=left, r=right, n=none),  hand stimulated with touch (l=left, r=right, n=none), onset/offset of the stimuls, respectively 1/2; e.g. onset auditory stimulus not presented and tactile stimulus presented to left hand in uncorssed posture:  u-an-tl-1.
