Hierarchical structures are rapidly and flexibly built up in the domains of human language and music. These domains require a tree-building capacity – “dendrophilia” – to dynamically infer hierarchical structures from sensory input (or to hierarchically structure output), based on subunits stored in a lexicon. This dynamic process involves a crucial class of abstracta overlooked in the target article.

动态分层认知：音乐和语言需要更多抽象类型

层次结构在人类语言和音乐领域迅速而灵活地建立起来。这些领域需要建立树的能力——“树突癖”——根据存储在词典中的子单元，从感官输入（或分层结构输出）动态推断层次结构。这个动态过程涉及到一个关键的类别抽象的在目标文章中被忽略。
