迄今为止的研究普遍支持任务前计划对语言产出有积极影响的说法，特别是在流利性和复杂性方面。然而，在准确的语言使用方面，人们发现了混合的结果（例如Ellis 1987; Crookes 1989）。这些变量结果的一个原因可能是，研究有不同的任务条件是否允许时间或鼓励仔细的在线规划（即制定和监测的讲话计划）。本研究旨在探讨任务前计划和在线计划对二语口语产出的影响。实验结果表明，任务前计划提高了语法复杂性，而任务后计划对准确性和语法复杂性有积极的影响。任务前计划者也比在线计划者产生了更流利和词汇多样的语言。这些发现有助于我们进一步了解规划和第二语言口语输出之间的相互关系，也是明显的教学相关性，因为它们表明了任务条件，以促进准确性，复杂性和流畅性，在独白语音生产。
Research to date lends general support to the claim that pre-task planning impacts positively on language production, especially where fluency and complexity are concerned. However, mixed results have been found for accurate language use (e.g. Ellis 1987; Crookes 1989). One reason for these variable results may be that studies have differed in whether the task conditions allowed time for or encouraged careful on-line planning (i.e. formulation and monitoring of speech plans). The present study was designed to investigate the effects of both pre-task and on-line planning on L2 oral production. The results show that pre-task planning enhances grammatical complexity while on-line planning positively influences accuracy and grammatical complexity. The pretask planners also produced more fluent and lexically varied language than the on-line planners. These findings help to further our understanding of the interrelationship between planning and L2 oral output and are also of obvious pedagogic relevance, as they indicate the task conditions needed to promote accuracy, complexity and fluency in monologic speech production.
