Preposition stranding vs. pied-piping - the role of cognitive complexity in grammatical variation

Abstract

Grammatical variation has often been said to be determined by cognitive complexity. Whenever they have the choice between two variants, speakers will use that form that is associated with less processing effort on the hearer’s side. The majority of studies putting forth this or similar analyses of grammatical variation are based on corpus data. Analyzing preposition stranding vs. pied-piping in English, this paper sets out to put the processing-based hypotheses to the test. It focuses on discontinuous prepositional phrases as opposed to their continuous counterparts in an online and an offline experiment. While pied-piping, the variant with a continuous PP, facilitates reading at the wh-element in restrictive relative clauses, a stranded preposition facilitates reading at the right boundary of the relative clause. Stranding is the preferred option in the same contexts. The heterogenous results underline the need for research on grammatical variation from various perspectives.
