This paper shows that Bosnian/Croatian/Serbian (BCS), like Slovenian, has three distinct strategies for subject-predicate agreement when the subject consists of conjoined noun phrases: (i) agreement with the maximal projection, a Boolean Phrase (&P); (ii) agreement with the conjunct that is closest to the participle; (iii) agreement with the conjunct that is hierarchically the highest. In order to test the initial hypothesis that there are three agreement strategies, a controlled experimental study of the morphosyntactic agreement between conjoined subjects and participles in BCS was conducted, consisting of three experiments: an oral-production experiment, a written-production experiment, and an acceptability-judgment task. The experiments showed a high presence of default agreement and closest-conjunct agreement. Of the preverbal conjoined phrases, 50% elicited default masculine agreement, while 95% of postverbal conjoined noun phrases elicited closest-conjunct agreement. However, the bulk of the analysis was focused on the possibility of treating highest-conjunct agreement (HCA) as a legitimate agreement strategy. The agreement forms in the preverbal-subject (SV) examples showed HCA 7% of the time. Moreover, acceptability-judgment results showed that scores for HCA examples ranged between 2 and 3 (1 = weakly acceptable; 5 = strongly acceptable). Last-conjunct agreement (LCA) for postverbal-subject (VS) examples, on the other hand, occurred only in 1% of the examples in the corpus, and these examples were mostly rated weakly acceptable by native speakers (1.5/5 on average). For this reason, they were classified as performance errors, eliminating LCA as an agreement strategy. The overall results go against Bošković (2009), who does not acknowledge HCA as a legitimate strategy, but they confirm the findings of Marušič, Nevins, and Badecker (2015).

波斯尼亚语/克罗地亚语/塞尔维亚语连体主语分词一致的语法*

本文表明，波斯尼亚语/克罗地亚语/塞尔维亚语 (BCS) 与斯洛文尼亚语一样，在主语由连体名词短语组成时具有三种不同的主谓一致策略：(i) 与最大投影一致，布尔短语 (&P)；(ii) 与最接近分词的连词一致；(iii) 与等级最高的合词一致。为了检验最初的假设存在三种一致性策略，我们对 BCS 中连体主语和分词之间的形态句法一致性进行了对照实验研究，包括三个实验：口语产生实验、书面产生实验和可接受性判断任务。实验表明默认一致性和最接近连接一致性的高度存在。在动词前连词短语中，50% 引起默认阳性同意，而 95% 动词后连词短语引起最接近连词同意。然而，大部分分析都集中在将最高联合协议 (HCA) 视为合法协议策略的可能性。动词前主语 (SV) 示例中的协议形式显示 HCA 有 7% 的时间。此外，可接受性判断结果显示 HCA 示例的分数介于 2 和 3 之间（1 = 弱可接受；5 = 强烈可接受）。另一方面，词后主语 (VS) 示例的最后连词 (LCA) 仅出现在语料库中 1% 的示例中，并且这些示例大多被母语人士评为弱可接受（平均 1.5/5 ）。因此，它们被归类为性能错误，取消 LCA 作为协议策略。总体结果与 Bošković (2009) 背道而驰，Bošković (2009) 不承认 HCA 是一种合法策略，但他们证实了 Marušič、Nevins 和 Badecker (2015) 的发现。
