Previous research focusing on direct object/subject garden path sentences, as in “While Anna dressed the baby played in the crib”, has provided evidence for the influence of multiple syntac-tic and non-syntactic factors on disambiguation. The present study sheds light on the role of a textual parameter that has received little attention in the literature: line breaks. In a self-paced reading study, participants were presented with multiline texts containing locally ambiguous optionally transitive verbs positioned before a line ending. By manipulating transitivity status, we investigated whether the intransitive analysis would be promoted – compared to the more commonly entertained transitive parse – as a function of the line break triggering early closure. Furthermore, we explored whether the presence of syntactically incomplete lines – as opposed to complete ones – preceding the verb region would cause readers to refrain from early closure due to an expectation of structural incompleteness. While results provided support to the first hy-pothesis, we found inconclusive evidence for the second. More specifically, no facilitation in reading rate was observed for either interpretation when the reader was primed with structurally incomplete lines; rather, an irregular reading pattern emerged in such contexts. Nevertheless, there was some evidence to suggest that when the parser operated on a prediction of structural incompleteness only to be proven false, comprehension was impacted. Further research is needed to confirm whether this is indeed a consequence of prediction error.
