The chapter ranges broadly over a number of topics, and summarizes the empirical findings on D. B. of 1986. It discusses issues that arose when blindsight research first emerged. These include stray light and other artefacts, with the appropriate controls that have been applied. The question of whether blindsight is degraded normal vision, together with other relevant research, is considered. The question of response criteria in signal detection terms is aired. Neural pathways and levels are reviewed together with a discussion of the differential physiological and anatomical properties of striate vs. non-striate pathways. A definition of blindsight is advanced, followed by a discussion of the importance of addressed issues of awareness in biology and for practical aspects of empirical research. The chapter ends with a discussion of the importance of ‘commentary keys’ for neuropsychological research and the underlying ‘commentary system’.

Keywords:   stray light, striate pathway, non-striate pathway, response critera, signal detection, degraded vision, commentary keys, commentary system
