Parallel Architecture is a theory of the mental representations involved in the language faculty. These representations are organized in three orthogonal dimensions or levels: phonology, syntax, and semantics, correlated with each other through interface links. Words are encoded in all three levels and serve as part of the interface between sound and meaning. In the representation of an entire sentence, the words are spread out across the combinatoriality of the three levels. An important requirement for a theory of language is that it must offer an account of how we can talk about what we see. It is proposed that conceptual structure in language interfaces with a level of physical space – which in turn interfaces with visual, haptic, and proprioceptive perception, and with the planning of action. Thus, the basic principles of the Parallel Architecture for language can be extended to major aspects of mental function. (#38684)
