Affective fields are constantly a major target for social canalization efforts. Specific activity contexts are used for the promotion of generalization of feeling beyond the given here-and-now context. The “social others” of the developing person suggest how the present situation can—or should—relate to the ways of being in general. In Chap. 10 , we have covered two major domains of cultural psychology—how language is limited (yet important) semiotic regulator of the personal-cultural domains, and how the multi-layered internalization/externalization process guarantees relative autonomy of the person in any state of his or her relationship with the social environment. Similarly, the non-isomorphic relation between ontogenesis, mesogenesis, and microgenesis guarantees relative buffering of each level against excessive events at the adjacent ones. The person as subjective agent—the maker of one’s own personal world through relating to its social guidance (canalization)—is enabled through the socially constructed systems of semiotic mediation.
