Note. The performance IQ is calculated from the Picture Completion, Digit Symbol Coding, and Matrix Reasoning subtests of the Wechsler Adult Intelligence Scale–Third Edition (Wechsler, 1997) using the approach from Sattler and Ryan (1999). The Modified Token Test (de Renzi & Faglioni, 1978; Morice & McNicol, 1985) scores are the group mean percentage correct. Spelling is the number of words spelled correctly of the 15 words presented from Fidler, Plante, and Vance (2011). Word Definitions is the group mean standard score for the subtest from the Clinical Evaluation of Language Fundamentals–Fourth Edition (Semel et al., 2003). DLI, developmental language impairment; TL, typical language.
