Congratulations Kendra, Pedro Antonio, Ana and Blanca! In their new JSLHR article, these smarties show that overt subject pronoun use in monolingual child Spanish-speakers can identify those with DLD/SLI with high degrees of sensitivity and specificity. Overt subject pronoun use in switch-reference contexts identifies 84% of DLD kids, by itself. Add in MLUw and you get 100% of kids with DLD.
Excellent use of variationist morphosyntactic research techniques with spontaneous production data from atypical language development.
