Self-monitoring and generalization were observed as eight preschool children progressed in management programs for their developmental phonological disorders. Changes in the production of target and non-target sounds and behaviors presumed to reflect self-monitoring were tallied as they occurred concurrently in conversational speech samples. With some notable exceptions, generalization data for target and non-target sound changes were consistent with linguistic patterns reported in the literature. Self-monitoring behaviors were observed to vary in type, frequency, and point of onset in relation to generalization data. A consistent observation across children was that self-monitoring behaviors neither always nor only occurred in temporal association with generalization. Alternative hypotheses concerning the occurrence of self-monitoring behaviors in stimulus and response generalization are considered.
