Abstract
This study examined the utility of eye tracking research technology to measure speech
comprehension in 14 young boys with autism spectrum disorders (ASD) and 15 developmentally
matched boys with typical development. Using eye tracking research technology, children were
tested on individualized sets of known and unknown words, identified based on their performance
on the Peabody Picture Vocabulary Test. Children in both groups spent a significantly longer
amount of time looking at the target picture when previous testing indicated the word was known
(known condition). Children with ASD spent similar amounts of time looking at the target and
non-target pictures when previous testing indicated the word was unknown (unknown condition).
However, children with typical development looked longer at the target pictures in the unknown
condition as well, potentially suggesting emergent vocabulary knowledge.
