摘要:AbstractWe focus on language processing and language modelling in the mother tongue and its dependence on “category width” cognitive style, and on social distance without social power. For this purpose, a transaction/sequence model was formulated and the data - requests in a given social situation were collected and applied. The C-W Scale and association rules analysis were used. The research was carried out at the university of Constantine the Philosopher in Nitra. The results indicate that a narrow categoriser uses only one simple expressive factor to manifest politeness at the beginning or in the middle of a request, while a broad categoriser uses more expressive factors and uses them at the beginning, in the middle and at the end of a request.
