Human language processing can be viewed as human processing of information. With a system, program, and options being necessary for information processing analysis, terms correlative with computer science should not be understood as an attempt to draw close a correspondence, as natural language remains a scope of skill unmatched by artificial parsing. Therefore, human neurophysiology shall be the primary  reference for the following discourse to conclude with the role of feedback in human language command.

Live organisms have been observed to use DNA-encoded information, for growth and sustainment. These genetic codes have been compared to programs (Young, 1984), where a program may be understood as a systematic plan for an automatic solution of a problem (Webster’s Encyclopedic Unabridged Dictionary of the English Language, 1989). Further, biological organisms have been posited to depend for activity on development and continued renewal of own internal structures (Young, 1984). Therefore, a problem as for the hitherto defined program can be comprehended as the task of homeostasis uphold to require substance selection and exchange within an environment.

The systemic selection and exchange to concern the single cell as well as complex structures such as human beings, a biological program may be exemplified by a DNA pattern for active protein production. Importantly, even basic programs of cellular activity can be claimed to rely on feedback for enactment (Vander et al., 1985), feedback to be defined here as returning of part the output of a system to be reintroduced as input (Webster’s Encyclopedic Unabridged Dictionary of the English Language, 1989).

Positive and negative feedback processes have been recognized, where the former, also known as regenerative feedback, aids the input, whereas the latter opposes it, hence the alternate term “inverse feedback”. As elementary cellular functioning accrues into schemata that allow learned behaviors, total and integrated patterns of human activity can be argued to build on feedback for their formation, effectuation, and permanence.

The role of feedback in controlling automatic operations was promoted by Norbert Wiener, who insisted that feedback processes appertained also with neuroscience. Within the perspective, feedback productiveness can be understood as a closed-loop capability over open-loop sequences (Puppel, 1988, 1996). The capacity would act in natural language, as a function of the human nervous system. The system shall be studied for feedback phenomena in cellular, intercellular, and interschematic dimensions.

For a competent insight into natural language, the inquiry shall include human communication as an interplay of intra-individual and inter-individual qualities. Psycholinguistics to constitute the framework for the intended quest, reliance on feedback shall be examined in language acquisition, use, and deficit. A principled occurrence to become affirmed in neurophysiological as well as psychological aspects of human living, dependence on feedback can be acknowledged to approximate a drive, the relevant instinct being that for self-preservation. In the view to human information processing, feedback would have the role of an initiating, mediating, and modeling factor.
