Relational network theory suggests a neurologically plausible organization of information applicable to both linguistic and non-linguistic information. The theory explains the access of linguistic information throughout multiple strata, from phonetic to conceptual and perceptual. The linguistic information system is represented as a relational network, a network of interrelationships. A stimulus, or a sequence of stimuli (e.g. speech sounds), triggers nodes in the network, activating corresponding pathways, activating one or more lexemes and corresponding concepts. Stimulation of a conceptual node can activate other conceptual nodes, as well as perceptual nodes, and connectivity is restricted in neither a bottom-up nor a top-down direction; thus lexemes can be activated by stimulation from both conceptual and phonemic nodes. Information is accessed in a bi-directional and stratum-independent manner.
