The effects of age and gender on the parameters A and b of the fits of the cumulative distributions to the logistic function. There were statistically significant effects of gender and age on the likelihood that the subjects in a group looked in the same direction (smaller A for older and male subjects); and there was a small, non-significant effect of age on the variability of direction of gaze (smaller b for younger subjects). Note that the ordinate axis for the upper panel (A) is logarithmic, since the fit and subsequent statistics were done to a, (loge A). Error bars indicate SEM.
