Which of the following are the two basic psychological functions of intra-personal communication? Choose the correct answer from the options given below.

The two basic psychological functions of intra-personal communication are internalising culturally organised ways of thinking and regulating one's own mental activity.

Internalisation means the individual takes in shared, culturally shaped patterns of thought and makes them part of the inner self.

Regulation means the person uses inner speech to plan, monitor and steer his or her own mental processes.

Promotion of leader-centric speech is an external, persuasive aim and no function of talk within the self.

Orientation towards enhancing social disorders is a harmful outcome, never a basic psychological function.

Inner speech, in Vygotsky's sense, thus both absorbs culture and governs one's own thinking.
