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).
