“…Moreover, dyslexic readers have been reported to not show the typical leftward asymmetry of the planum temporale (e.g., Hynd, SemrudClikeman, Lorys, Novey, & Eliopulos, 1990;Larsen, Høien, Lundberg, & Odegaard, 1990), although reports have been inconsistent (for a review, see Heim & Keil, 2004). Structural abnormalities of the planum temporale and surrounding areas have further been associated with other developmental speech and language disorders like specific language impairment (e.g., Badcock, Bishop, Hardiman, Barry, & Watkins, 2012) or stuttering (e.g., Foundas et al, 2004). We therefore interpret the significant positive relationship between left superior temporal gray matter volume and subsequent changes in reading proficiency as evidence for preexisting neurostructural differences, which might be associated with differences in general linguistic abilities.…”
