Abstract
Substantial evidence points to the presence of subtle weaknesses in the nonlinguistic cognitive processing skills of children with primary (or specific) language impairment (PLI). It is possible that these weaknesses contribute to the language learning difficulties that characterize PLI, and that treating them can improve language skills. To test this premise, we treated two nonlinguistic cognitive processing skills, processing speed and sustained selective attention, in two Spanish–English bilingual children with PLI. The study followed a single-subject multiple baseline design, with both repeated measures and standardized pre- and post-testing as outcome measures. Results from the repeated measures tasks showed that both participants made gains in nonlinguistic cognitive processing skills as well as in Spanish and English. These results both replicate and extend prior work showing that nonlinguistic cognitive processing treatment can positively affect language skills in children with PLI.
