Along with physical brain structures, researchers also believe that the function of language comprehension is supported by a type of mental storage system that includes various aspects of language called the mental lexicon. This suspected mental lexicon stores information including word meanings (semantic info), how words can be combined to form sentences (syntactic info) and details of different forms and sound patterns of words (Gazzaniga, Irvy, & Mangun, 2018). With this storage system, the human brain can quickly process word-form activations based off of intended input or output (lexical access), select best matches from the storage device to match input or output (lexical selection), and integrate words into full sentences in order to develop coherent communication in the form of language, or lexical integration (Gazzaniga, Irvy, & Mangun, 2018).
