Interesting and related: Noam Chomsky, in his work as linguist, has stated that what reaches the ear (or the eye in this case) is not what reaches the mind. What this means is that we experience language as if it was linearly ordered, when at the cognitive level (in the mind) language is actually hierarchically organized. This means that the underlying structure of language has to interface with the sensory-motoe systems in order to transform the hierarchical structure into a linear one. This is why we sometimes also struggle putting our thoughts into words, because in that interface there is a change in structure that doesn't always preserve the 'original' (hierarchical) structure
