In the male group, these relationships were somewhat weaker but still highly significant: the correlation between fusion and flicker was 0.302 ( p = 0.023) and between fusion and average it reached 0.776 ( p < 0.001), comparable to the correlation between flicker and average (r = 0.792, p < 0.001).
Although statistical analysis has indicated that these differences are significant, they were at the limit of significance ( p = 0.049).
Flicker frequencies were not correlated with age in any of these groups, although we observed a statistical trend across men (r = 0.229, p = 0.086), while in the group of women r = 0.020, p = 0.888.
As in other studies, RTs exhibited a strong overall correlation with age, highlighting a clear trend of slower responses as participants aged [ 43 , 63 ].
