Peabody Picture Vocabulary Test (PPVT; Dunn & Dunn, 2007) standard scores provided. List length (average of last 2 correctly recalled) provided for forward and backward digit and block span tasks. Percent correct for whole nonwords, syllables, and phonemes provided for nonword repetition task. Diadochokinetic (DDK) rates are presented as number of syllables per second. No significant group differences found on these tasks (all <i>p</i>s > .05). <div><br></div><div>Steinberg Lowe, M., & Buchwald, A. (2017).
