An evolutionary explanation of graph comprehension using fMRI

Abstract

Evolution has equipped Homo sapiens with a wide range of inherent abilities. One of those abilities is comprehending graphical representations. We claim that comprehension is only inherent if the representation has an analogy in the evolutionary environment. We test this using a fMRI study to show that certain graphs activate the visual cortex and others do not. Furthermore those that activate the visual cortex result in greater accuracy.
