Choice of analysis pathway dramatically affects statistical outcomes in breaking continuous flash suppression

Abstract Breaking Continuous Flash Suppression (bCFS) has been adopted as an appealing means to study human visual awareness, but the literature is beclouded by inconsistent and contradictory results. Although previous reviews have focused chiefly on design pitfalls and instances of false reasoning,...
