Incidental teaching focuses on child-initiated interactions. (Hall, 2013) Incidental teaching is used to increase skills of individuals with autism spectrum disorders. (Hall, 2013) A study done by Hart and Risley (1975) looked at the incidental teaching process used at the preschool age to aide in teaching language. Incidental teaching has been the most frequent strategy that has been used to teach language. When using incidental teaching a child’s request may be verbal or nonverbal. Examples include reaching for an object that is out of one’s reach, requesting food or a toy or calling an adult’s name. There is a series of decisions that an adult can use to respond to the child’s request. These choices include: if the occasion should be used for incidental teaching: if so then a choice regarding the language behavior that is obtained from the child, and then a choice has to be made concerning the cue that will be used to initiate instruction, the cur could be focus of attention by itself, or in addition to the focused attention a verbal cue as well. If the individual does not respond to the cue, then a choice concerning the degree of prompt to be used, the “fullest degree: a request for imitation; medium degree: a request for partial imitation, or minimal degree: a request for the terminal language behavior.” (Hart & Risley, 1975) This study was performed on boys and girls between the ages of four years old to five years old. The baseline procedures ensured that the children had a variety of vocabulary for use in sentences. The sentences that they were taught was “I want x so I can y.” The second step of the procedure was the use of incidental teaching of compound sentences directed to teachers. After thirty-six days of school, the incidental teaching began to occur when the children needed assistance in trying to get different preschool materials.
