In this module Cate discusses using dynamic assessment using repetition of nonwords, sentences and syllables (Dollaghan & Campbell, 1998) to help confirm Alex’s diagnosis of developmental apraxia.
Alex’s variable productions and distortion during non-word repetition indicate that apraxia is indeed the likely diagnosis. Cate considered other possible diagnoses (selective mutism and second language acquisition) before confirming apraxia as the source of Alex’s communication difficulty. As with previous modules, Cate indicates where the information gathered would go in the final evaluation.
