iv. Qualify as at risk for persistent language disorder by meeting two out of three criteria (STUDY 1 AND 2).
Score at or below the 10th percentile on the MacArthur-Bates Communicative Development Inventory-III (CDI-III) Sentences section using sex-specific norms. For children over 37 mos., score must be less than or equal to the 10th percentile equivalent for 37 mos.
AND
- Score at or below the 10th percentile on the CDI-III Vocabulary section using sex-specific norms. For children over 37 mos., score must be less than or equal to the 10th percentile equivalent for 37 mos. The child must also produce at least 10 different words on either the CDI-III or CDI-Words and Sentences (CDI-WS long form).
OR 3. Score at or below -1.25 standard deviations on the Expressive Communication scales of the PLS-5 (STUDY 2).
v. Meet cognitive inclusion criteria.
- Score greater than or equal to 70 standard score (-2 SD) on the Cognition subtest of the DAYC-2 (STUDY 1)
- Score greater than or equal to 30 t-score (-2 SD) on the Visual Reception scale of the Mullen (STUDY 2).
vi. Have no parent reported disabling developmental or acquired disorders/impairments that might significantly affect their performance beyond speech-language disorders (e.g., ASD, cancer, stroke, legal blindness, intellectual disability, Down Syndrome, traumatic head injury, cerebral palsy, seizures, or a genetic condition associated with neurodevelopmental disability other than DLD; STUDY 1 AND 2).
vii. Pass the Modified Checklist for Autism in Toddlers-Revised with Follow-Up screener (STUDY 1 AND 2) OR the Screening Tool for Autism in Toddlers and Young Children (STUDY 2).
c. DLD+ASD Group (STUDY 2) i. 2;6-4;0:0 at the start of testing ii. English dominant (at least 80%) iii. Pass hearing screening at 25 dB in both ears across 500, 1000, 2000, and 4000 Hz OR no parent-reported diagnosed hearing loss (or no concerns if the child has not been tested).
iv. Have received ASD diagnosis from a healthcare professional prior to beginning the study.
v. Qualify as at risk for persistent language disorder by meeting two out of three criteria.
Score at or below the 10th percentile on the MacArthur-Bates Communicative Development Inventory-III (CDI-III) Sentences section using sex-specific norms. For children over 37 mos., score must be less than or equal to the 10th percentile equivalent for 37 mos.
AND
