Just as the educational level of the people influences the way they use their language, likewise, the way of expressing themselves of the individuals changes according to the situations: the same person will be expressed in a way in a family meeting and another in a job interview. These variations in the use of language that are directly related to social factors are, precisely, those studied in sociolinguistics.
Anthropological linguistics: the need to study the indigenous societies and languages of aboriginal peoples led to the emergence and development of anthropological linguistics: a discipline that examines the languages of the remains of peoples in relation to their society and particular cultures.
Psycholinguistics: due to the close link that exists between language and thought, it is important to study the mental processes involved in this relationship, since this allows a better knowledge of the way in which human thought and cognition processes work. In addition to the above, psycholigistics is concerned with examining the mental and linguistic mechanisms involved in the acquisition of the mother tongue or a second language.
