刺激贫乏论是语言习得研究中最有争议的论点之一。在这里，我们遵循以前的方法挑战贫困的主要语言数据的假设，专注于辅助（AUX）前置在复杂的极性疑问句的具体问题。我们开发了一系列的语料库分析的儿童导向的讲话表明，有间接的统计信息有用的正确的辅助前置极性疑问句，这些信息是足够的语法和不合语法的概括之间的区别，即使在没有直接证据。我们进一步表明，有简单的学习设备，如神经网络，能够利用这种统计线索，产生一个偏向正确的AUX问题相比，他们的不符合语法的同行。研究结果表明，刺激贫困论的基本假设可能需要重新评估。
The poverty of stimulus argument is one of the most controversial arguments in the study of language acquisition. Here we follow previous approaches challenging the assumption of impoverished primary linguistic data, focusing on the specific problem of auxiliary (AUX) fronting in complex polar interrogatives. We develop a series of corpus analyses of child-directed speech showing that there is indirect statistical information useful for correct auxiliary fronting in polar interrogatives and that such information is sufficient for distinguishing between grammatical and ungrammatical generalizations, even in the absence of direct evidence. We further show that there are simple learning devices, such as neural networks, capable of exploiting such statistical cues, producing a bias toward correct AUX questions when compared to their ungrammatical counterparts. The results suggest that the basic assumptions of the poverty of stimulus argument may need to be reappraised.
