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 1 (Experiment 1): Subaim 1a: Identify child characteristics associated with learning from overhearing. In a prior study, the investigators found that 13 children with ASD were able to learn the meanings of novel words that they heard used in a conversation involving two adults. In the current study, the investigators aim to study a larger sample to identify what child characteristics are associated with good learning in an overhearing situation as compared to a situation in which the child is directly taught the new word. Subaim 1b: Assess retention and generalization of words learned from overhearing. The investigators will re-test children on their knowledge of the word meanings after a 10-minute delay to see if they both retain the word meanings and can generalize the new words to new situations.

Study Groups

Addressed

Children participate in an interaction with an experimenter who uses the word to be learned.

Group Type: EXPERIMENTAL

Addressed Speech

Intervention Type: BEHAVIORAL

New words are introduced directly to the child by an experimenter.

Overheard

Children observe while an experimenter uses the word to be learned in an interaction with another experimenter.

Group Type: EXPERIMENTAL

Overheard Speech

Intervention Type: BEHAVIORAL

New words are introduced with the child as an observer rather directly taught.
