On the L1-acquisition of the pragmatics of discourse like

This study analyzes the L1-acquisition of discourse like and its pragmatic functions in American English based on the Home-School Study of Language and Literacy Development component of the Child Language Data Exchange System (CHILDES). The data show that discourse like is already present in the speech of 3- and 4-year-old children and that even very young children employ like to perform distinct pragmatic functions with specifying uses being dominant until age 8;5. The analysis also shows a notable increase in discourse like as children mature, mainly driven by an increase in attention-directing like, the dominant function of discourse like among children older than 8;5. Conditional inference trees show that the use of discourse like by children is affected by a child’s age, the situation type and the frequency of discourse like in caregivers’ input. Children younger than 7;10 use discourse like only rarely in formal contexts as well as in informal contexts if their caregivers do not use discourse like frequently. However, children use discourse like substantially more if they are older than 7;10 or, in informal contexts, when their caregivers use discourse like frequently. The changes in frequency and the functional shifts in the use of like around the ages of 7 to 9 is interpreted to show that peers become more important as linguistic role models when children enter school. The results thus substantiate research which suggests that the pragmatic and social meanings of discourse markers are learned alongside linguistic constraints rather than after the form has been acquired.
