The acquisition of obligatory-do

The auxiliary verb obligatory-do is used in forming questions, negative and emphatic sentences. Currently there is no test or norms established for the acquisition of obligatory-do. The purpose of this study was to establish age trends, via elicited imitation for the acquisition of obligatory-do according to the sentence type in which it expressively occurs i.e., negative sentences, emphatic sentences, interrogative reversals and wh-questions. This study addressed the following question: At what ages do children expressively demonstrate, via elicited imitation, the auxiliary verb obligatory-do in negative sentences, emphatic sentences, interrogative reversals and wh-questions? A secondary question was: In what manner does age and MLU, mean length of utterance, of 25 utterances correlate with the acquisition of obligatory-do?
