Autism Spectrum Disorder
Conditions
Brief summary
The goal of this research is to explore abilities to learn word meanings from overheard conversations in children with ASD (and, as a control, typically developing children). Specific Aim 2 (Experiment 2): Determine whether children with ASD can learn from addressed and overheard teaching via videoconferencing. The investigators will use a similar procedure to Study 1, except that both overheard and directed teaching will take place on video.
Interventions
New words are introduced with the child as a bystander rather directly taught.
New words are introduced directly to the child by an experimenter.

Outcome results
Proportion of Time During Which Children's Eye Gaze is Directed Toward the Target Object
Children's eye gaze is recorded as they look at images. The proportion of time during which gaze is directed to an image of the targeted word is the dependent measure.
Time frame: immediately after viewing 3-minute interaction
Population: Not all enrolled participants were analyzed because of exclusions due to, e.g., experimenter error or children paying insufficient attention.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| ASD - Addressed | Proportion of Time During Which Children's Eye Gaze is Directed Toward the Target Object | 0.42 proportion of time | Standard Deviation 0.35 |
| ASD - Overheard | Proportion of Time During Which Children's Eye Gaze is Directed Toward the Target Object | 0.44 proportion of time | Standard Deviation 0.33 |
| TD - Addressed | Proportion of Time During Which Children's Eye Gaze is Directed Toward the Target Object | 0.49 proportion of time | Standard Deviation 0.34 |
