The idea that social interaction involves trade in attention and other valued resources is the central insight of:

A) symbolic interactionism
B) exchange theory
C) norm of reciprocity
D) rational choice theory
E) dramaturgical analysis

The idea of trade in valued resources is the core concept of exchange theory, which suggests that social interactions are based on individuals exchanging resources that they perceive to be valuable. Symbolic interactionism focuses on how individuals create and interpret symbols, while the norm of reciprocity refers to the social expectation that favors should be reciprocated. Rational choice theory emphasizes that individuals make choices based on self-interest, while dramaturgical analysis suggests that social interactions can be seen as performances on a stage. Overall, exchange theory is the best fit for the description of trade in valued resources.
