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.

the duration of study participation (approximately 10 minutes)
Our experimental paradigm involves presenting children with videos of everyday child-friendly actions during a 10-minute interaction. There is no risk of Serious Adverse Events or All-Cause Mortality during the session.

| The primary statistical analysis involves asking whether children's preference to look at the target is significantly greater in one condition and/or group than the other. Mixed-effects regression analyses are used with the proportion-empirical-logit transformed-of target looking as the dependent measure, participant as random effect, and condition and group and their interaction as fixed effects. | Regression, Linear | 0.22 | This is the p-value for the simple effect of group. | Other |
