This a novel intervention to train the speed and accuracy of attention orienting and eye movement. The training is designed to target attentional behaviors that have been shown to be impaired in autism, including attention orienting, disengagement and shifting, and a restricted attentional field. Because eye movement and attention are tightly linked, eye movement deficits in ASD parallel those found in spatial attention. Eye movements provide a marker for attention and the proposed training is designed to improve speed, accuracy and flexibility of eye movement and attention simultaneously. Training uses a series of entertaining video games to gradually shape behavior using visual and auditory feedback provided in real time. The investigators plan three levels of outcome measures for pre- and post-training to test the effectiveness of the intervention (direct tests of attention and eye movement; tests of improvement in attentional and visual monitoring and speed and accuracy of response in a simulated environment; tests of behavior in an actual social environment). The investigators will conduct clinical trials with control conditions (e.g., standard video games without training elements) with a small sample of ASD children aged 9-15. If this initial work is successful, the long term goal is to develop a readily available inexpensive eyetracker-based system for home use that is suitable for a broad age range of ASD children and adults.
