本研究以西班牙语学习者口语语料库为研究对象，探讨了西班牙语过去时态形态的任务变异性。来自三个不同水平的60名西班牙语（英语L1）学习者（每组20人）和15名母语者完成了三项交际任务（引导式访谈，基于图片的叙事和历史人物描述）和一项实验任务，所有这些任务都旨在调查习得时体在L2西班牙语。将数据转录到CHAT中，并使用专门创建的交互式编码程序进行分析和编码，该程序与CLAN程序结合使用（MacWhinney 2000）。结果表明，在出现和准确使用过去时态形态跨任务的显着差异。一个额外的分析表明，较少控制的任务鼓励更先进的功能的一些实例，这表明，并不是所有的任务类型都同样成功地引出了一系列的时体形态对比理论上相关的二语习得研究的时体。
This cross-sectional study investigates task variability focusing on the use of Spanish past tense morphology in a spoken learner corpus. Sixty L2 learners of Spanish (English L1) from three different proficiency levels (20 per group) and fifteen native speakers completed three communicative tasks (a guided interview, a picture-based narrative, and a historical figures description) and an experimental task, all designed to investigate the acquisition of tense and aspect in L2 Spanish. Data were transcribed in CHAT, and analysed and coded using a specially created interactive coding program that works in combination with the CLAN program (MacWhinney 2000). Results demonstrate significant differences in the emergence and accurate use of past tense morphology across tasks. An additional analysis showed that the less controlled tasks encouraged few instances of more advanced features, suggesting that not all task types are equally successful at eliciting the range of tense-aspect morphological contrasts theoretically relevant for SLA research on tense and aspect.
