“To produce language, speakers must decide what they want to say and how they want to say it – that is, they must formulate a preverbal message and a corresponding utterance. At the sentence level, the formulation process involves several steps. For example, when asked to describe a picture of a dog chasing a mailman, speakers must select referential terms from a range of potentially suitable nouns (e.g., man or mailman to refer to the patient in this event) and must select one out of a range of suitable syntactic structures (e.g., active, passive, or intransitive constructions). Numerous production studies have see more shown that the

availability of lexical and structural information can influence selection processes as well as production speed (e.g., Bock, 1986a, Bock, 1986b and Smith and Wheeldon, 2001). Questions about the relative contributions of words and structures to grammatical encoding have inspired a number of hypotheses about interactions between these processes ( Bock, 1982, Bock and Griffin, 2000, Hartsuiker et al., 2008 and Pickering and Branigan, 1998) and have led to the development of detailed production models (e.g., Chang et al., 2006 and Kempen and Hoenkamp, 1987). Differences between models reflect different assumptions about the division of labor between lexical and structural processes

in the shaping of sentence form (Bock, 1987a). On the one hand, lexicalist accounts propose that structure building has a lexical source (e.g., Bates & MacWhinney, O-methylated flavonoid 1982): retrieving a word provides access to structural information stored with this word at the lemma level and thus triggers the assembly of a syntactic structure. On the other hand, abstract structural accounts posit that structures can also be built by lexically-independent structural procedures (Bock, 1986a): when preparing their utterances, speakers may first generate an abstract structural framework and then retrieve the necessary words in the order required by these structures. Experimental work testing these accounts is found in the production (Bock, 1986a and Bock, 1986b, and others) as well as acquisition (Fisher, 2002 and Tomasello, 2000) literature. Here we take the position that debates about the relative timing of lexical and structural encoding are also important for explaining how speakers formulate and map preverbal messages onto language. Namely, production processes can be divided into two large classes, one concerned with encoding of individual elements of a message (non-relational processes) and the other concerned with encoding the relationships between them (relational processes). The distinction applies both to sentence-level and message-level encoding.
