Although statistical graph comprehension has been investigated in cognitive psychology, it has not been reported in cognitive neuroscience. The study designed an experimental condition, i.e., a statistical graph (SG), and two control conditions, i.e., a text (ST) and a statistical graph with text (SGT), where the ST is a verbal description of the information from the SG, and the SGT is a mixed graph + textual description. We used fMRI to analyze the brain activity of 36 normal subjects while they passively view the statistical information presented in any of SG, ST, and SGT. The results indicate that statistical graph comprehension requires the involvement of both ventral and dorsal streams, with more dependence on the ventral stream than the dorsal.
