This report addresses the lack of progress in the field of Second Language Attrition (L2A). Review of L2A history and literature show this to be cause by lack of appropriate data. Five criteria for appropriate data are suggested and a corpus of L2A data (57,000 words, spoken Spanish) which meets the criteria is presented. The history of the corpus is explained in detail, including subject selection, instruments and methods of collection, and markup -- XML was used to annotate the corpus with nineteen categories of speech errors, adapted from Nation's (2001) "Learning Vocabulary in Another Language." An example analysis of how the corpus can be used for L2A research is provided with step-by-step instructions on writing scripts for data extraction and post-processing in the Perl language. Source code is included in the text. Complete beginners tutorials on the XML and Perl languages are included in the appendices. The report also introduces a website, developed specifically to host the corpus, where researchers may register, download the corpus and share work they have done with the corpus. All files used in the example project, as well as this report, are available for download at the website. Findings from the example analysis support Plateau Phases, the Regression Hypothesis and suggest the Threshold Hypothesis does not apply to marked forms. This shows the corpus to be of great value to the L2A research community.

Three adults volunteered to participate in this project. The data collection was carried out through open interviews, which allowed the construction of the narratives about their life stories marked by immigration and the passage of a productive and receptive bilingualism to a loss situation in which subjects see the former domain of a language decline in several ways, reaching a strictly receptive use of a previously spoken language. The narratives were analyzed through the perspective of sociocognitive and sociopragmatic theories in order to investigate the phenomenon of losing a language due to social contexts and factors. The loss of a language, caused by external factors, is a phenomenon that has to do mainly with two contexts which are essential to speakers linguistic and communicative evolution: family and school contexts. This paper examines these contexts in life stories narrated by speakers, filtered by their subjectivity and by the interpretations these speakers gave to the phenomenon of losing, although partially, a language. / Utilizando narrativas, este texto trata da perda de línguas em falantes que, por razões externas (sociais), passaram por um processo de perda linguística e comunicativa. Três indivíduos adultos ofereceram-se para participar deste projeto, cuja coleta de dados foi realizada mediante entrevistas abertas, construindo narrativas de histórias de vida marcadas pela imigração e pela passagem de um bilinguismo produtivo e receptivo a uma situação de perda em que os sujeitos veem o domínio anterior de uma língua diminuído de várias formas, chegando até a um uso estritamente receptivo da língua falada anteriormente. As narrativas são analisadas do ponto de vista teórico do Sociocognitivismo e da Sociopragmática, com o fim de investigar o fenômeno da perda de uma língua a os contextos e fatores sociais envolvidos nesse processo. A perda de uma língua, causada por fatores externos, é um fenômeno que tem a ver, sobretudo, com dois contextos que são muito importantes na evolução linguística e comunicativa dos falantes, o contexto familiar e o escolar. Este texto examina esses contextos nas histórias de vida narradas pelos falantes, filtrados pela subjetividade dos falantes e das interpretações que eles dão ao fenômeno da perda, ainda que parcial, de uma língua.
