  1. Note. n = 56 for typical development, n = 29 for mild condition, and n = 27 for moderate/severe condition. A r of |.1| is a small effect, |.3| is a medium effect, and |.5| is a large effect [51].
  2. *p-value (one-way) < .017.
  3. a n = 45 for typical development, n = 27 for mild, and n = 24 for moderate/severe.
