Seeing events vs. entities: The processing advantage of Pseudo Relatives over Relative Clauses.

• Pseudo Relative (PR) availability modulates Relative Clause (RC) attachment in French. • Tense mismatch forces RC-parse, lowering acceptability of locally ambiguous strings. • RC-disambiguation leads to longer fixation durations at critical region. • No effects of tense manipulation in globally unambiguous RCs. • No main effect/interaction in English, a language which disallows PRs. We present the results of three offline questionnaires (one attachment preference study and two acceptability judgments) and two eye-tracking studies in French and English, investigating the resolution of the ambiguity between pseudo relative and relative clause interpretations. This structural and interpretive ambiguity has recently been shown to play a central role in the explanation of apparent cross-linguistic asymmetries in relative clause attachment (Grillo and Costa, 2014; Grillo et al., 2015). This literature has argued that pseudo relatives are preferred to relative clauses because of their structural and interpretive simplicity. This paper adds to this growing body of literature in two ways. First we show that, in contrast to previous findings, French speakers prefer to attach relative clauses to the most local antecedent once pseudo relative availability is controlled for. We then provide direct support for the pseudo relative preference: grammatically forced disambiguation to a relative clause interpretation leads to degraded acceptability and greater processing cost in a pseudo relative environment than maintaining compatibility with a pseudo relative.
