It's actually a spectrum of disorders, a spectrum that ranges, for instance, from Justin, a 13-year-old boy who's not verbal, who can't speak, who communicates by using an iPad to touch pictures to communicate his thoughts and his concerns, a little boy who, when he gets upset, will start rocking, and eventually, when he's disturbed enough, will bang his head to the point that he can actually cut it open and require stitches.
它事实上是一整个谱系发生了失调， 自闭症谱系有很多种表现形式： 比如，13岁的贾斯丁， 他不能说话， 只能利用 iPad 与人交流， 通过触碰图像 来表达他的想法和担忧。 另一位得了自闭症的男孩 在难过时会不断摇摆晃动， 要是足够心烦了， 他会撞自己的头， 一直撞到头破血流，需要进行缝线。
