Children with autism spectrum disorders vary considerably in their language abilities, but even verbally proficient children have difficulty with two aspects of language: pragmatic inference, which uses context to understand the meaning of a sentence, and prosodic comprehension, which uses speakers' tone to understand the feelings, attitude and information they wish to convey. Dr. Snedeker and her colleagues are examining in real time the processes that occur as children understand language. Rather than ask children to point at pictures or answer questions, Snedeker and colleagues use a computer to track children's eye movements as they listen to sentences while viewing a corresponding scene. The timing and direction of the children's gaze provide clues to how they process information in a sentence. Snedeker's team has found that eye movements can also be used to measure complex grammatical processes. The researchers plan to track eye movements to determine whether highly verbal children with autism can also use prosody and pragmatics to guide language comprehension.
