Eyetracking, sound localization latency in infants and young children

Gaze intercepted AOI and time stamps for each sample were sent from the eye-tracking system to the presentation system by a low latency network connection. The time stamps from the presentation and eye-tracking systems were synchronized off-line by subtracting the minimum difference between the two systems from the eye-tracking system time stamps and adding a system latency (sound card buffer and eye tracker processing) of 19 ms. The collected eye-tracking data was stored in a text files and a compiled
