Looking while listening (LWL) tasks track eye movements while children view images (e.g., a dog and a ball) and hear an auditory prompt (e.g., "Find the ball"), allowing researchers to measure receptive language in populations who may be difficult to test with traditional measures. However, LWL tasks often result in high levels of missing data and accurately measuring receptive language in autistic children remains a challenge. We analyzed data from 18 autistic children ages 2-5 years and examined whether adding visual movement of the named image improved LWL accuracy compared to a static condition. This study also investigated whether receptive language abilities on a standardized assessment moderated the effect of condition (i.e., static vs. movement) on LWL accuracy. There was evidence of comprehension in both conditions, although children showed faster recognition in the static compared to the movement condition. Standardized language abilities did not moderate the effect of condition on LWL accuracy. However, as standardized receptive language scores increased, accuracy increased. Findings indicate that the visual movement manipulation in the current study did not improve accuracy compared to traditional static images within the LWL task. These results also suggest a continued need to refine LWL tasks in order to improve LWL methodology and refine receptive language measures for autistic children.
