Grammar in Boys With Idiopathic Autism Spectrum Disorder and Boys With Fragile X Syndrome Plus Autism Spectrum Disorder

Conclusions Despite being similar on mean length of utterance, there were group differences on grammatical performance. The sentence imitation task had good convergent validity with a norm-referenced assessment of grammar for the third-person singular and past tense probes and therefore could be an inexpensive and valid tool to use clinically for these populations. Future research should continue to refine this task, particularly for the probes with high rates of unscorable responses (i.e., “be” and “do”).
