Note. SLI = specific language impairment; AM = age-matched group; VM = vocabulary-matched group. K-ABC II SS = Nonverbal scale of the Kaufman Assessment Battery for Children - Second Edition Standard Score (Kaufman & Kaufman, 2004); PPVT-III SS = Peabody Picture Vocabulary Test—3rd Edition Standard Score (Dunn & Dunn, 1997); EVT SS = Expressive Vocabulary Test Standard Score (Williams, 1997); EVT-RS = Expressive Vocabulary Test Raw Score; BBTOP WI = Bankson-Bernthal Test of Phonology Word Inventory Standard Score (Bankson & Bernthal, 1990); CASL-SC SS = Comprehensive Assessment of Spoken Language Sentence Completion Subtest Standard Score (Carrow-Woolfolk, 1999); CASL-PC = Comprehensive Assessment of Spoken Language Paragraph Comprehension Subtest Standard Score; CASL-A RS = Comprehensive Assessment of Spoken Language Antonyms Subtest Raw Score. SPELT-III SS = Structured Photographic Expressive Language Test—3rd Edition Standard Score (Dawson, Stout, & Eyer, 2003); SPELT-P RS = Structured Photographic Expressive Language Test-Preschool Raw Score (Werner & Kresheck, 1983). Bus Story- I RS = Renfrew Bus Story Information Units Raw Score (Cowley & Glasgow, 1994); Bus Story - L RS = Renfrew Bus Story Sentence Length Raw Score; NWR-PPC = Nonword Repetition Percent Phonemes Correct (Dollaghan & Campbell, 1997).

SPELT-III administered only to 4- and 5-year olds (n = 92).

SPELT-P administered only to 3-year olds (n = 33).

Due to technical problems scores for the NWR task are not available for all participants, SLI n = 30, AM n = 32, VM n = 37.
