In this article we examine language processing and development in Catalan or Spanish-speaking children with SLI, focusing on the study of the verb. We analyse the key initial phase of its process of acquisition and aim to define common features of the SLI group that distinguish them from children with normal language development. We intend to identify more precisely the kind of delay shown by these children in a language with a rich verb morphology, in terms of both structure and chronology. The sample comprised 18 Catalan-Spanish bilingual pre-school children, assigned to three groups of six; an SLI group and two control groups, one matched for age and the other matched for MLU-w. Developmental data were obtained by recording situations of spontaneous speech at two different time points. Certain differences were found between groups in verb production. Production of verb inflection by children with SLI was only partial at the first evaluation; they maintained the same percentage of errors after a year. The patterns of correct and incorrect verb forms found in Catalan and Spanish do not corroborate the EOI hypothesis, but they support the Surface Hypothesis, given that the number of errors is not particularly high. This suggests the presence of limitations in subjects' processing ability, linked to the typological characteristics of the specific language being learnt.
在本文中，我们研究了患有特定语言障碍（SLI）的加泰罗尼亚语或西班牙语儿童的语言处理与发展情况，重点关注动词的研究。我们分析了其习得过程的关键初始阶段，旨在确定SLI组与正常语言发展儿童相区别的共同特征。我们打算更精确地确定这些儿童在一种具有丰富动词形态的语言中，在结构和时间顺序方面所表现出的延迟类型。样本包括18名加泰罗尼亚语 - 西班牙语双语学前儿童，分为三组，每组六人；一个SLI组和两个对照组，一个按年龄匹配，另一个按平均语句长度（MLU - w）匹配。通过记录两个不同时间点的自发言语情境来获取发展数据。在动词产出方面，各组之间发现了某些差异。SLI儿童在首次评估时动词屈折变化的产出仅为部分情况；一年后他们的错误率保持不变。在加泰罗尼亚语和西班牙语中发现的正确和错误动词形式模式并未证实“早期产出指标”（EOI）假设，但支持“表面假设”，因为错误数量并不特别高。这表明受试者的处理能力存在局限性，这与所学特定语言的类型特征有关。
