A trio of researchers from Aston University, the University of Cambridge and Royal Holloway University of London has mapped the neural process that occurs during conversion of symbols that are read to understanding what they mean. In their paper published in Proceedings of the National Academy of Sciences, Jo Taylor, Matthew Davis and Kathleen Rastle describe fMRI studies they carried out with volunteers and what they learned from them.
Processing occurs in the brain when converting given symbols to meaningful information. The first time a reader encounters an acronym on Twitter, for example, they learn it, and from then on, the conversion happens naturally. In this new effort, the researchers sought to learn more about what actually happens in the brain when that conversion occurs.
To better understand the conversion process, the researchers asked 24 English-speaking volunteers to learn to read and recognize words in an unfamiliar symbolic language. Each of the words were assigned meanings that correlated with words (nouns) they knew in English. Next, each of the volunteers was asked to submit to fMRI scans as they read the words that they had learned in their training classes.
