Note. GMFCS = Gross Motor Function Classification System; TACL-4 = Test for Auditory Comprehension of Language–Fourth Edition; SS = standard score; CP = cerebral palsy; TD = typically developing; F = female; M = male.

^a GMFCS rating: I = no/mild impairment, V = severe impairment.

^b TACL-4 standard score: M = 100, SD = 15.
