Effects of labeling and pointing on object gaze in boys with fragile X syndrome: an eye-tracking study.

摘要: We examined the visual processing of a social learning stimulus and ways in which attention was distributed to objects as well examiner's face during word under conditions that varied only presence or absence label. The goal current study, then, evaluate effects differentially providing pointing labeling exposure novel target object males with fragile X syndrome (FXS) (n=14, ages 4.33-10.02), autism spectrum disorder (ASD) (n=17, 4.04-10.4), typical development (TD) (n=18, 2.05-5.33). In particular, present study distracter were presented video stimuli. An eye-tracker captured gaze stimuli they shown order examine way children FXS, ASD, TD their toward examiner objects. Results indicated no group showed increased compared object. However, results revealed participants FXS significantly objects, whereas ASD both similar amounts relative Furthermore, act at found increase when there all groups. Together, these findings suggest cues like those employed word-learning task, video, may relate context- task-dependent are distinct from expected live interaction.
