Primary Outcome Measures

Name	Time	Method
Emergence of intraverbal responses	Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks)	The goal of intervention is the mastery of 80% of evaluated intraverbal responses (2 for each target, 18 total).
Change in Mean Length of Utterances (MLU) during manding	Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks)	The mean length of utterances (MLU) during manding will be evaluated in a 10 minute probe. The goal of intervention is to increase of MLU to an average of 3 words per mand.
Acquisition of noun-verb and color-shape combinations during tacting	Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks)	The goal of intervention is mastery of 80% of evaluated noun-verb and color-shape targets.

Secondary Outcome Measures

Name	Time	Method
Change in Macarthur Bates-Communicative Development Inventory (CDI) Score	Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks)	The Macarthur Bates-Communicative Development Inventory (CDI) is completed by a parent/caregiver and evaluates current word use . A higher score indicates the use of more words.
Observe overall improvements in pragmatic language within social/play interactions with parents/caregivers, as measured on the Direct Observation of Spoken Language (DOSL).	Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks)	A goal of the intervention is to observe an increase in spontaneous mands, an increase in spontaneous tacts, as well as an increase in intraverbal responses.
