在自然界,刺激贫乏是普遍存在的,是不言而喻的道理。语言刺激是贫乏的,甚至是缺乏的。大量句法、音系和形态证据,尤其是由基因导向的语法规则的结构依赖性表明,刺激贫乏是儿童语言习得过程中的自然现象,语言不是学会的。各种反对刺激贫乏论的观点,误解了刺激贫乏论及其内在逻辑,低估了语言的复杂性,也缺乏有效的、严肃的理由。 In nature, it is self-evident that stimulating poverty is ubiquitous. Language stimulation is poor, even lacking. A large number of syntactic, phonological and morphological evidence, especially the structural dependence of gene-driven grammar rules, show that impaired learning is a natural phenomenon in children’s language acquisition and language is not learned. Various arguments against stimulus leanism misunderstood stimulating leanism and its inherent logic, underestimating the complexity of language, and lacking valid and serious reasons.
