This table shows the means and standard deviations as well as the medians and ranges across subjects of our 18 oculometric measures under dominant and non-dominant eye viewing along with parametric (t-test) and non-parametric (Wilcoxon test) comparisons. p-values with an asterisk indicate t-tests for which the normality criterion was not met. Bolded p-values indicate significant effects (p < 0.05).
