A major issue in psychology concerns the nature of unconscious processes and how they differ from conscious processes. Research on this issue has relied on various types of methodology and provided various results with sometimes contrary implications on the extent and limits of unconscious perceptual processes. In this talk I will provide an overview of the functional and neurophysiological characteristics underlying continuous flash suppression (CFS), masking and crowding. I will also present experimental studies from our group directly comparing the strength of nonconscious influences obtained across these three methods. I will argue for the necessity of rigorous comparisons between the different methods employed to prevent perceptual awareness.
