Tag construction: structure and function in child discourse.

Abstract

ABSTRACTA distinction has been drawn between tag questions which occur within the same temporally defined turn and those in a second turn by the same speaker. A TAG CONSTRUCTION has been defined as a MATRIX CLAUSE (any syntax) and a TAG FORM (reduced interrogative in elliptical constructions; or interrogative expression in stereotypical constructions) produced WITHIN THE SAME TURN. The discoursal functions of tag constructions include requests for information, agreement, permission, compliance, responsiveness and attention. Although stereotypical tag constructions emerge earlier in development than elliptical tag constructions, from the beginning stereotypical tag constructions perform the same discoursal functions as the grammatically more complex elliptical constructions as well as additional ones. Tag constructions are less effective than canonical questions in obtaining turn transfers. This relative ineffectiveness may be due to either the post-positioned clearance signal or the fact that the listener feels less compelled to respond when the speaker seems to have an expectation as to what the response to the request should be.
