Young Romance speakers can structure their sentences by dislocating multiple constituents to the left periphery, resulting in non-canonical word orders. Production data, however, show that this ordering is rigid: only SOV sequences are attested, an observation reminiscent of Superiority. The first goal of the paper is to replicate this observation in comprehension; the second is to derive the Subject-over-Object pattern in terms of Intervention, with the additional assumption that only nested chains count as interveners. Three experiments are reported here. Experiment 1 and Experiment 2 show that SOVs interpretations are systematically favored over OSV and that not only Number features, but also a [+Topic] feature help to overcome intervention. Experiment 3 addresses a potential confound related to the clitic. These results integrate existing intervention-based accounts, traditionally built on relatives, providing not only new evidence coming from matrix clauses, but also investigating the role of information-structure features.

对意大利左翼外围多重运动优势的观察：对嵌套依赖的干预效果和信息结构特征的作用

年轻的罗曼语使用者可以通过将多个成分错位到左边缘来构建句子，从而导致不规范的词序。然而，生产数据表明这种排序是严格的：只有 SOV 序列得到证明，这一观察让人想起优越性。本文的第一个目标是在理解中复制这一观察结果；第二个是根据干预推导主体优于客体模式，并附加假设只有嵌套链才算作干预者。这里报告了三个实验。实验 1 和实验 2 表明，SOV 解释在系统上优于 OSV，并且不仅数字特征，而且 [+主题] 特征都有助于克服干预。实验 3 解决了与附加词相关的潜在混淆。这些结果整合了传统上基于亲属的现有基于干预的账户，不仅提供了来自矩阵条款的新证据，而且还调查了信息结构特征的作用。
