This chapter focuses on psycholinguistics of language production. It provides empirical evidence for and against the two-stage model of language production, which assumes separate levels for functional (semantic and syntactic) processing, as well as for positional processing. The chapter also discusses the results of studies supporting the existence of lexically independent structure building operations in language production in addition to lexical representations. It also contends that lexically independent structural processes often receive a straightforward interpretation as abstract constructions in a Construction Grammar framework.
