Reading Goals and Executive Function in Autism: An Eye-Tracking Study.

The sources of reading comprehension difficulties in people with autism spectrum disorder (ASD) are still open to discussion. We explored their ability to adapt reading strategies to different reading goals using eye-tracking technology. A group of participants with ASD, and intelligence-, receptive oral language- and reading skills-matched control peers, read three stories under three different reading goals conditions: read for entertainment; read for study; and read fast and search information for a previously presented question. Each text required participants to answer comprehension questions. The ASD group was less accurate in question answering. The control group was faster in reading questions, displayed more fixations on the text, and reported to be more confident in question answering during reading for study compared to reading for entertainment. These differences between reading goals were not observed in the ASD group. The control group adopted and was aware of using different reading strategies according to different reading goals. In contrast, the ASD group did not change their reading behavior and strategies between entertainment and study reading goal condition, showing less of a tendency to adopt deep-level processing strategies when necessary. Planning, as measured by Tower of Hanoi, was the only executive task that predicted individual differences in text reading time across conditions. Participants with better planning ability were also able to adapt their reading behavior to different reading instructions. Difficulties in adjusting the reading behavior according to the task, evaluating own performance and planning may be partly involved in reading comprehension problems in ASD. LAY ABSTRACT: The control group read questions faster, reported to be more confident in question answering during reading for study compared to reading for entertainment, and were aware of using different reading strategies according to different reading goals. In contrast, the autistic group did not change their reading behavior and strategies according to the reading goal. Difficulties in adjusting the reading behavior according to the task, in evaluating own performance and in planning may be partly involved in reading comprehension problems in autism.
