2. Do you think that even sighted people benefi t from the visual pathways that give blindsighted people the ability to respond to visual information? Have you ever, for example, reacted to something that you “saw” without being consciously aware that you saw it? We have noted the important distinction between sensation and perception, and we have examined the processes that underlie both of them. We’ve seen how external stimuli evoke sensory responses and how our diff erent senses process the information contained in those responses. We also have focused on the physical structure and internal workings of the individual senses, including vision, hearing, balance, smell, taste, and the skin senses, and we’ve explored how our brains organize and process sensory information to construct a consistent, integrated picture of the world around us.
