Relational network theory

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 a phonemic stratum to a conceptual stratum. The linguistic information system is represented as a relational network, a network of interrelationships. A stimulus, or a sequence of stimuli (e.g. a string of phonemes), triggers a node in the network, activating corresponding pathways (known as lines) and the intersecting nodes and consequently activating the lexeme and the corresponding sememe. Stimulation of a conceptual node can activate other conceptual 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.
