简要总结
The purpose of the study is to evaluate a 2-3 day treatment probe targeted to improving social gaze behavior in children with fragile X syndrome (FXS). The investigators will use the principles of Applied Behavior Analysis (ABA) to shape appropriate social skills. Importantly, the investigators propose to examine the effects of this treatment probe on brain and behavior.
