According to several linguists, neurocognitive research has confirmed many standards of language learning, such as: " learning engages the entire person ( cognitive, affective, and psychomotor domains ), the human brain seeks patterns in its searching for meaning, emotions affect all aspects of learning, retention and recall, past experience always affects new learning, the brain's working memory has a limited capacity, lecture usually results in the lowest degree of retention, rehearsal is essential for retention, practice does not make perfect, and each brain is unique " ( Sousa, 2006, p. 274 ).

The correlation between damage to certain specific brain areas ( usually in the left hemisphere ) and the development of specific types of aphasia makes it possible to deduce ( albeit very roughly ) the location of a suspected brain lesion based only on the presence ( and severity ) of a certain type of aphasia, though this is complicated by the possibility that a patient may have damage to a number of brain areas and may exhibit symptoms of more than one type of aphasia.
