Interrogatives in dialogue: case study of mother and child 16-19 months.

Question-answer sequences were examined within the dialogues of a mother-infant dyad. Mother and male infant were observed at the infant's ages of 16, 17, 18, and 19 months. The structure, content, and function of the mother's questions were analyzed in conjunction with the child's contingent responses. The child exhibited an increase in overall responsiveness to his mother's questions for the period observed. In terms of question structure and content, at about 17 months the mother began to ask more of those questions to which the child responded with a higher percentage of relevant-appropriate responses. In terms of question function, no single systematic pattern of change occurred in the frequencies of various question functions and responses. It was concluded that the present data describe a process of simultaneous change in the direction of greater congruency between mother and child behaviors, although further research is needed to determine the generalizability of the present results.
