A recent paper in Experimental Brain Research from Emory neuroscientist Krish Sathian and colleagues demonstrates that congenitally blind study participants displayed superior verbal, but not spatial abilities, when compared to their sighted counterparts. This may reflect both greater reliance on verbal information, and the recruitment of the visual cortex for verbal tasks.
Sathian’s team has also been investigating, through brain imaging studies, whether the visual cortex is involved in the processing of metaphors (2016 SFN abstract) in the congenitally blind. They previously showed that blind study participants were better at identifying rotated objects by touch. Read more
