Examined were the home verbal environments of three multiply handicapped language impaired children (3, 6, and 8 years old). Each child wore an FM transmitter-microphone for 3 1/2 consecutive days. Prliminary analysis of the acoustic data was in terms of actual data time, parental lesson time, and number of engaged (verbal interactions) and unengaged times in the natural environment. Descriptive analysis was then performed along four dimensions: an overview of the household, the vocal controls directed to the child, the vocal movements displayed by the child, and the non-vocal movements displayed by the child which were the setting for engagements. Two major conclusions were that each child spent the major portion of the day unengaged thus limiting the opportunities for the establishment of verbal behavior; and that the nature and functions of the engagements which did take place were unlikely to enhance the establishment of verbal behavior. The results underscored the need for parent education programs. (DB)
