Note. CELF–R = Clinical Evaluation of Language Fundamentals—Revised; NRT = Nonword Repetition Task; CLPT = Competing Language Processing Task; IQ = intelligence quotient; SLI = specific language impairment; E = expressive language impairment; ER = expressive and receptive language impairments.

^aFor nonverbal IQ, either the Leiter International Performance Scale—Revised or the Columbia Mental Maturity Scale was used.

^bExpressed in years;months.days.

^cThis child would not repeat any nonwords.
