The current study investigated whether young children with autism spectrum disorder (ASD), like typically developing children, associate novel labels with unfamiliar objects—a word-learning constraint known as mutual exclusivity. Unlike previous studies of children with ASD, we utilized an eye-gaze paradigm that provided information about children’s looks to familiar and unfamiliar images in real time. Participants were 21 typically developing toddlers and 21 toddlers with ASD matched on nonverbal cognition. Each trial of the eye-gaze task presented two objects: one familiar and one unfamiliar. In the Real Word condition, children heard a familiar label (e.g., Find the book). In the Nonword condition, children heard a novel label (e.g., Find the dofa). Children in both groups looked significantly more at the target images after noun onset than at baseline, suggesting that children treated the familiar words as labels for the familiar objects and the novel words as labels for the unfamiliar objects. Research is needed to determine whether children with ASD have difficulty using mutual exclusivity to retain new words, despite good initial performance.
