Note: Values for CELF-P expressive, receptive, and composite scores are reported in standard scores with a mean of 100 and an SD of 15; values for CELF-P subtests are reported in standard scores with a mean of 10 and an SD of 3; WPSSI-R scores are reported in standard scores with a mean of 10 and an SD of 3. NS-LI = nonspecific LI; LI = language impairment; TD = typically developing controls; LNIQ = low nonverbal IQ; CELF-P = Clinical Evaluation of Language Fundamentals–Preschool; WPSSI-R = Wechsler Preschool and Primary Scale of Intelligence–Revised.
