Motor Skills
Among adolescents, A-SOD have demonstrated stronger bimanual (Barbeau et al., 2015) and eye movement skills (Takarae et al., 2004) than A-NoSOD matched for IQ, age, and gender. Uniquely, A-SODs’ motor problems dinot relate to their perceptual reasoning scores (Barbeau et al., 2015). This could suggest that motor problems may interfere with their speech rather than their nonverbal intelligence. Bimanual coordination may suggest stronger communication across the brain’s hemispheres and regions (Gooijers & Swinnen et al., 2004). ASODs’ better eye movement skills may suggest developmental catch-up in part through flexible visual scanning (Kelly, Walker, & Norbury, 2013).
