Table 1.
Mean Study 1 characteristics for younger and older subgroups of children in the Language Impaired (LI) and Typically Developing (TD) groups: age at testing, Verbal IQ (VIQ), Performance IQ (PIQ), CELF-R Expressive Language (ELS) and Receptive Language (RLS) scores. Standard scores have a mean equal to 100 with a standard deviation equal to 15.
