be susceptible to attrition if a) the corresponding property in the L2 input can be processed with sufficient success to be fully acquired in the L2, and b) the property shares enough similarity in the L1 and L2 for the L2 property to be incorporated into the L1 grammar. This predicts that attrition principally occurs "for aspects of the L1 grammar which share featural properties to a significant degree, but where differences nevertheless obtain" (Hicks and Dominguez, 2019:160). While this prediction appears to be supported by the existing literature, the only property which has been extensively investigated is pronouns, and to date very little is known about other grammatical features (Schmid, 2020). While the AvA model claims that grammatical attrition is dependent upon 'extensive' input from an L2 (Hicks and Dominguez, 2019:154), it makes no specific prediction about the role length of residency plays in L1 grammatical attrition. Schmid (2019:291) has recently argued that the role played by length of residency in the context of attrition has long been under investigated and that there is extremely little evidence on how attrition might progress during the first years following migration. This is because most attrition studies to date have focused on participants with a substantial length of residency in the L2- speaking country (e.g. a minimum residency length of 10 years in Cuza, 2010; 15 years in Dominguez and Hicks, 2016). My study addresses these two significant empirical gaps identified in the L1 attrition literature; testing grammatical properties which have previously received little or no attention, and pinpointing the duration of L2 exposure necessary to engender grammatical attrition. I will test for grammatical attrition among native Spanish speakers who have emigrated to Portugal after childhood: Iverson (2012) has shown the L1-Spanish/L2-Portuguese language combination to be favourable to grammatical attrition in a case study of an attriting Chilean-Spanish speaker living in Brazil for 30 years. My study will recruit groups of participants living in Portugal for varying lengths of time, paying particular attention to the first few years following migration. The participants will undertake experimental language production and comprehension tasks designed to reveal their L1 knowledge of a set of specifically selected grammatical properties exhibiting differences between Spanish and Portuguese. Quantitative analysis will compare their results to those of monolingual Spanish controls in Spain to determine if L1 grammatical attrition has in fact occurred, at what length of exposure to the L2, and for which grammatical properties. Providing important new data focusing on significant gaps in our understanding of L1 grammatical attrition, this research will demonstrably benefit the academic community in language acquisition and linguistic theory, as new understanding of the nature of attrition will advance our understanding of the cognitive architecture of the human language faculty itself (Hicks and Dominguez, 2019; 2020).

如果a）L2输入中的相应属性可以足够成功地被处理以在L2中被完全获取，并且B）该属性在L1和L2中共享足够的相似性以使L2属性被合并到L1语法中，则该属性容易受到损耗。这表明，磨蚀主要发生在“母语语法的某些方面，这些方面在很大程度上共享特征属性，但仍然存在差异”（Hicks and Dominguez，2019：160）。虽然这一预测似乎得到了现有文献的支持，但唯一被广泛研究的属性是代词，到目前为止，对其他语法特征知之甚少（Schmid，2020）。虽然AvA模型声称语法磨蚀取决于来自L2的“广泛”输入（Hicks and Dominguez，2019：154），但它没有具体预测居住时间在L1语法磨蚀中的作用。Schmid（2019：291）最近认为，长期以来一直在调查居住时间在自然减员中所起的作用，并且很少有证据表明自然减员在移民后的头几年可能会如何发展。这是因为迄今为止的大多数流失研究都集中在在L2语言国家居住时间较长的参与者（例如，Cuza的最低居住时间为10年，2010年; Dominguez和Hicks的最低居住时间为15年，2016年）。我的研究解决了这两个显着的经验差距，确定在L1的摩擦文学，测试语法特性，以前很少或根本没有得到关注，并查明L2曝光的持续时间必要的产生语法摩擦。我将测试童年后移民到葡萄牙的西班牙语母语者的语法磨蚀：Iverson（2012）在一个案例研究中表明，L1-西班牙语/L2-葡萄牙语的语言组合有利于语法磨蚀，该案例研究是一个在巴西生活了30年的智利-西班牙语母语者。我的研究将招募在葡萄牙生活不同时间的参与者群体，特别关注移民后的头几年。参与者将进行实验性的语言生产和理解任务，旨在揭示他们的L1知识的一组具体选择的语法属性表现出西班牙语和葡萄牙语之间的差异。定量分析将他们的结果进行比较，在西班牙的单语西班牙语控制，以确定是否L1语法磨损实际上已经发生，在什么长度的曝光L2，以及哪些语法属性。这项研究提供了重要的新数据，重点关注我们对L1语法磨蚀理解的重大差距，将明显有利于语言习得和语言理论的学术界，因为对磨蚀性质的新理解将促进我们对人类语言能力本身认知结构的理解（希克斯和多明格斯，2019; 2020）。
