The concept of low-level functions was first introduced in Germany through a contribution by Professor Martin Ptok (“ Auditory processing and perception disorders and dyslexia ”, Hessisches Ärzteblatt 2/2000, pp. 52–54). Ptok shows the hierarchical structure of the language from the low-level level to the phonetic , phonological , lexical-semantic and morphological-syntactic level to the spelling level. He shows that this hierarchical structure also means that the competence at each level is dependent on all levels below.

Indications of such a dependency within the lower three levels can be found in a study by N. Buller "Basic auditory processing skills and phonological awareness in preschool age" - lecture at the 1st annual meeting of the Society for Aphasia Research and Treatment in Bielefeld November 1st - 3rd 2001: Here the connection between low-level disorders and the phonological level was clarified for the time being. "The results presented here indicate that as early as preschool age one for the acquisition of written language correlates relevant poor phonological awareness with impaired basal auditory processing." At her reference to the "for the acquisition of written language relevant phonological awareness" refers Buller to Professor W. Schneider , who has demonstrated the importance of phonological awareness for learning to read and its trainability in longitudinal studies and has thus proven the associated relationship between levels 3 and 5 of the above Ptok model.

A therapy model for dyslexia, dyslexia or LRS, which is based on this hierarchical acquisition of linguistic competence and extends the concept of low-level functions in vision and motor skills, has now become known as the Warnke procedure .
