Human activity can be realized in two forms: “mental” activity or internal activity and practical objective or external activity (Leont’ev, 1981). The fundamental and primary form of human activity is external and practical. This form of activity brings humans into practical contact with objects thus redirecting, changing and enriching this activity. The internal plane of activity is formed as a result of internalizing external processes. “Internalization is the transition in which external processes with external, material objects are transformed into processes that take place at the mental level, the level of consciousness” (Zinchencho & Gordon, 1981, p.74).
