We present a new dorsal-ventral stream framework for language comprehension which unifies basic neurobiological assumptions (Rauschecker & Scott, 2009) with a cross-linguistic neurocognitive sentence comprehension model (eADM; Bornkessel & Schlesewsky, 2006). The dissociation between (time-dependent) syntactic structure-building and (time-independent) sentence interpretation assumed within the eADM provides a basis for the division of labour between the dorsal and ventral streams in comprehension. We posit that the ventral stream performs time-independent unifications of conceptual schemata, serving to create auditory objects of increasing complexity. The dorsal stream engages in the time-dependent combination of elements, subserving both syntactic structuring and a linkage to action. Furthermore, frontal regions accomplish general aspects of cognitive control in the service of action planning and execution rather than linguistic processing. This architecture is supported by a range of existing empirical findings and helps to resolve a number of theoretical and empirical puzzles within the existing dorsal-ventral streams literature.
我们提出了一个新的语言理解的背-腹流框架,它将基本的神经生物学假设(Rauschecker 和 Scott,2009)与跨语言神经认知句子理解模型(eADM;Bornkessel 和 Schlesewsky,2006)统一起来。eADM 中假设的(时间依赖的)句法结构构建和(时间独立的)句子解释之间的分离为理解中的背侧和腹侧流之间的分工提供了基础。我们假设腹侧流执行时间独立的概念图式的统一,以创建越来越复杂的听觉对象。背侧流参与元素的时间依赖组合,既支持句法结构,又与动作联系起来。此外,额区在动作规划和执行方面完成一般的认知控制,而不是语言处理。这一架构得到了一系列现有实证研究结果的支持,并有助于解决现有背-腹流文献中的一些理论和实证难题。
