Reading is a practically important example of inference and language, and a leading researcher on
dyslexia has recently reviewed the current state of knowledge of how brains manage to read. Maryanne Wolf points out that literacy is a recent development in human history, going back only about five thousand years, to the Sumerians. There is no evidence that the brain evolved special functions to support reading; rather, reading is like many other cultural developments in using neural mechanisms that evolved for other reasons. Wolf describes how successful reading requires interactions among several brain areas, including occipital, temporal, and frontal regions. Difficulties in reading can arise because of problems with particular areas, such as the angular gyrus, but also because of interactions between or among different areas. Neural explanations of reading ability and dyslexia are still sketchy and provisional, but the prospects for further advances in the understanding of these and other features of language use appear strong.
