Dynamic collaboration of reading neural pathways driven by the processing demands
Abstract: Constructing unified cognitive and neurophysiological models is the central problem in the cognitive neuroscience of word reading. The cognitive models agree that reading is the collaborative outcome of phonological and semantic processing pathways, and studies of cognitive neuroscience have also shown that reading results from a dynamic collaboration between dorsal and ventral neural pathways. To systematically clarify this dynamic collaboration mechanism within the reading network, the latest developments in neurological function and physiological basis was integrated into the following three aspects. Firstly, it points out that the underlying processing demand is the essence of the dynamic collaboration of dorsal/ventral neural pathways. Subsequently, it further clarifies that the processing demand drives the division of labor between dorsal/ventral neural pathways at different orthographic depths. Finally, it delves into the exploration of how processing demand forms the dynamic collaboration between neural pathways shaped by language experience. In conclusion, the essence of the division and collaboration between neural pathways might be driven by processing demand under the specific task. It might become a universal cross-language word reading model.
