Here we investigated how music reading experience modulates visual spans in language reading. Participants were asked to identify music notes, English letters, Chinese characters, and novel symbols (Tibetan letters) presented at random locations on the screen while maintaining central fixation. We found that for music note reading, musicians outperformed non-musicians at some peripheral positions in both visual fields, and for English letter reading, musicians outperformed non-musicians at some peripheral positions in the RVF but not in the LVF. In contrast, in both Chinese character and novel symbol reading, musicians and non-musicians did not differ in their performance at peripheral positions. Since both music and English reading involve a left-to-right reading direction and a RVF/LH advantage, these results suggest that the modulation of music reading experience on visual spans in language reading depends on the similarities in the cognitive processes involved.
