Children use whole-part juxtaposition as a pragmatic cue to word meaning

When parents label novel parts of familiar objects. they typically provide familiar whole-object terms before offering novel part terms (e,g.. "See this cup? This is the rim."). Such whole-part juxtaposition might help children to accurately interpret the meaning of novel part terms, but it can do so only if they recognize the conjunction as a potential cue to part meaning. Two studies examined (a) whether 3- to 4-year-olds use whole-part juxtaposition to accurately interpret novel part terms and (b) how the), might do so. Study 1 confirmed that children indeed use juxtaposition to guide learning of novel part terms. Furthermore. 2 control conditions clarified that children's use of juxtaposition was not simply due to memory effects. such as the facilitation of lexical access, nor to recognition of the grammatical frame that typically accompanies juxtaposition. Study 2 revealed that children readily use juxtaposition in a novel, gestural format. Such flexibility in recognizing and utilizing novel variants of juxtaposition strongly suggests that pragmatic understanding lies at the heart of children's sensitivity to whole-part juxtaposition.
