Sentence Production

In sentence production, as in comprehension, the mapping between thematic and grammatical roles and the construction of syntactic structure must be included in the processing stages. The processing stages in sentence production include the message level stage, in which a conceptual representation of the sentence is formed, two stages of linguistic encoding, and an arti-culatory stage. Thematic role relations between actions and entities are assumed to be represented at the message level. At the first level of linguistic encoding (termed the functional level), the message level information is used to select lexical representations

(i.e., semantic-syntactic lexical representations) and to construct grammatical relations among these lexical representations based on the thematic role and other semantic information in the message. The prosodic structure of the sentence is also encoded during this stage. Prosodic factors such as word stress (the emphasis given to words) and intonation (using pitch to signify different meanings) are important methods of varying speech to facilitate communication. The second level of linguistic encoding (called the positional level) creates the syntactic structure for the sentence in terms of word order, function words, and grammatical markers (e.g., plural markers and past tense inflections). The phonological forms for the content words are also retrieved at this stage. Once the phonological representations have been retrieved, plans for articulation can be formed.

We have all been there: turning to the refrigerator if feeling lonely or bored or indulging in seconds or thirds if strained. But if you suffer from bulimia, the from time to time urge to overeat is more like an obsession.
