Prerequisite for logical and scholarly ability, human language processing can be viewed as human processing of information. Terms as a system, program, and option being necessary for analysis of information processing phenomena, notions correlative with computer science need not imply 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 comprehend 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). The task of homeostasis uphold, to require substance biological selection and exchange within an environment, can serve an example of a problem for programs as hitherto defined.
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, aid the input, whereas the latter oppose it, hence the alternate term “inverse feedback”. Elementary cellular functioning to accrue into schemata that allow learned behaviors, integrated patterns for human activity shall be argued to build on feedback for formation, effectuation, and permanence.
Norbert Wiener insisted that feedback processes appertained with neuroscience, based on the role in controlling automatic operations. Neurophysiologically and psychologically, 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 to be that for self-preservation. In the view to human information processing, feedback would have the role of an initiating, mediating, and modeling factor.
 Human information processing: natural, biological and psychological operating on sense-data, with or without alteration to source or initial content.
 The Latin pars orationis meant a part of speech.
 Primary: first in development and fundamental. The discourse begins with reference to neurophysiology and continues with language psychology.
 Homeostasis: internal balance or relative equilibrium.
 Problem: a context that requires action or resolve, which does not have to imply perplexity or trouble, especially within information frameworks.
 Systemic: regarding system properties in a live structure. Please discern systemic from systematic, regular, measured.
 Schema, plural schemata, from Greek schema, form, shape, figure. Here, a schema is a biological structure, as a neural pattern or compound neural connectivity to act in accord. Please discern the use from schematic, as inflexible, mechanical, or mathematical.
 Psycholinguistics: a study of psychological factors in speech and language to regard learning, use, and deficit, inclusive of the biological background.
 Principled: expressive of a principle as a strong regularity of natural, unconditioned occurrence.
 Drive: a natural, unconditioned need or urge by a live organism, to originate in an instinct. The sense does not follow Freudian uses.
