Mean reaction times, accuracy scores (in % errors) and their standard deviations in the left and right visual field of the visual half field tasks.

The mean (and standard deviation) lateralization index is calculated based on formula 1 (see main text). Cohen’s d is provided as effect size measure of the visual half field differences and is based on the means, standard deviation and correlation of both visual half fields. For the dichotic listening task, the means and standard deviations of left and right ear matches are reported instead of reaction times.
