Note. CLPT = competing language processing task; GJLSPT = grammatical judgment listening span task; NRT = nonword repetition task; SWMT = spatial working memory task; AWM = Auditory Working Memory subtest of the Woodcock-Johnson–3. Subscripts indicate significant pairwise differences (p < .01) between the group within that column and the other groups indicated.
