![]() ![]() In this article, we want to re-examine this debate in the light of recent advances in the characterization of blindsight and associated phenomena. From these studies, two main opposing models of the underlying mechanisms have been established: (a) blindsight is perception without consciousness or (b) blindsight is in fact degraded vision, two views that mirror more general theoretical options about whether unconscious cognition truly exists or whether it is only a degraded form of conscious processing. This phenomenon hence presents a unique opportunity to study consciousness and perceptual consciousness, and for this reason, it has had an historical importance for the development of this field of research. Blindsight types differentially impact objective and subjective perception, patients can report having no visual awareness whilst their behaviour suggests visual processing still occurs at some cortical level. ![]() Blindsight regroups the different manifestations of preserved discriminatory visual capacities following the damage to the primary visual cortex. ![]()
