Mid technology in the treatment of autism and related pervasive developmental disorders involves electronic devices used to aid communication. Many individuals who have autistic disorder never develop speech. However, many do have the capacity to receptively understand language. Mid technology provides the means of expressive language that the autistic individual lacks. Common devices used to help an individual express himself include a tape recorder as well as devices created especially for communication. The Voice in the Box is an augmentative communication device that contains recorded messages that correspond to buttons with images on them. The individual uses the icons on the buttons to determine what message he wants to play.
