| Label | Type | Description | Intervention Names |
|---|---|---|---|
| One Baseline Session | Experimental | Designated for participants #1 and #2. Participants complete 1 Baseline Session followed immediately by 12 weeks of standard treatment. Standard treatment will require the participant to attend clinic-based treatment sessions for 1 hour per day, 3 days per week, for 12 weeks. Standard treatment will consist of 3 components: mand training, matrix training, and stimulus equivalence training. |
|
| Two Baseline Sessions | Experimental | Designated for participants #3 and #4. Participants complete a Baseline Session followed by a 12 week wait period before repeating a Baseline Session followed immediately by 12 weeks of standard treatment. Standard treatment will require the participant to attend clinic-based treatment sessions for 1 hour per day, 3 days per week, for 12 weeks. Standard treatment will consist of 3 components: mand training, matrix training, and stimulus equivalence training. |
|
| Three Baseline Sessions | Experimental | Designated for participants #5 and #6. Participants complete a Baseline Session followed by two repetitions of the Baseline Session (each 12 weeks apart) and 12 weeks of standard treatment immediately following the third session. Standard treatment will require the participant to attend clinic-based treatment sessions for 1 hour per day, 3 days per week, for 12 weeks. Standard treatment will consist of 3 components: mand training, matrix training, and stimulus equivalence training. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Mand Training | Behavioral | The mand training component of treatment will consist of behavioral principles designed to increase the participant's Mean Length of Utterances (MLU) when manding. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Mean Length of Utterances (MLU) during manding | 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. | Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks) |
| Acquisition of noun-verb and color-shape combinations during tacting | The goal of intervention is mastery of 80% of evaluated noun-verb and color-shape targets. | Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks) |
| Emergence of intraverbal responses | The goal of intervention is the mastery of 80% of evaluated intraverbal responses (2 for each target, 18 total). | Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks) |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Macarthur Bates-Communicative Development Inventory (CDI) Score | 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. | Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks) |

| Matrix | Behavioral | The matrix training component of treatment will consist of behavioral principles designed to teach labeling of noun-verb and color-shape combinations using matrix training. |
|
| Stimulus Equivalence Training | Behavioral | The stimulus equivalence training component of treatment is designed to examine the emergence of untrained skills following the training of relational skills. |
|
| Observe overall improvements in pragmatic language within social/play interactions with parents/caregivers, as measured on the Direct Observation of Spoken Language (DOSL). |
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. |
| Baseline (Up to 24 Weeks), End of Standard Treatment (Up to 36 weeks) |
