Information structure and scope interactions: disjunction wide scope induced by focus

In this paper we investigate the scopal reading of disjunctions in French negative sentences with pre-schoolers. We posit that the French disjunctor “ou” does not fit the traditional disjunction PPI/non-PPI dichotomy according to which a wide scope is taken by a PPI disjunction and a narrow scope when the disjunction is not a PPI. We hypothesized that focus could be a succesful scopal manipulator. Using Truth Value Judgment Tasks (TVJT), we tested French pre-schoolers' scopal reading of negated disjunctions in a neutral prosody condition and with prosodic focus on the disjunctor in a between subject design. We found that as predicted, prosodic focus often enduced participants to adopt a disjunction wide scope reading whereas a disjunction narrow scope reading was favored in the neutral prosody condition. This confirmed our hypothesis that focus can manipulate disjunction scope paramaters. It also shows that, when the disjunction is focalised, children have access to the disjunction wide scope reading earlier than previously thought. Finally, we can conclude that the distinction between PPI-disjunctor vs. non-PPI disjunctor languages needs to be more fine-grained
