To the Editor: Dr. Klin et al. (1) presented evidence for abnormalities in the visual behavior of autistic subjects in filmed social interactions. They reported that autistic subjects looked more at objects, and when looking at faces, they fixated mostly on mouths instead of eyes. We studied the fixation patterns of autistic children shown faces and objects as well, but in static conditions, and did not find any abnormalities in fixation parameters (2, 3). Dr. Klin et al. suggested that their results were the reflection of a core social deficit. However, we feel that a different interpretation is warranted, given the fact that visual abnormalities were not seen with the static stimuli used in our studies.
