Hi everyone,
In eye-movement tracking studies with babies, it is sometimes difficult to get a perfect calibration. I wonder if there are well-established criteria, thresholds or recommendations for excluding calibrations.
Any input - tutorials, method reviews or drawn from researchers' own experience would be very helpful.
Second, has anyone experienced slighted shifted calibrations (i.e. experimenter perceives that the baby is looking at the right target but the ET maps the eye-mvt with a shift, e.g. to the right direction probably due to issue with the initial calibration)? Are there ways to correct those or shall the participants' data be discarded?
