University of California, Los Angeles
The University of Iowa Twenty single-subject investigations on early language interventions were reviewed. Treatments included direct reinforcement of verbalization and various training procedures including mand-model and time delay, and have generally been successful. Quantitative synthesis procedures utilizing a percentage of non-overlapping data outcome metric suggested that specific generalization training procedures were associated with stronger outcomes than were "train and hope" methods or assessments of spontaneous generalization. Implications for training and future research are discussed.
