This chapter continues our discussion of the properties of interdependence situations. It first considers the two conditions that affect how people can go about using their outcome controls to select among the various pairs of outcomes made possible in a situation. These are the response conditions – the sequential-temporal structure that governs when and in what order the behavioral responses possible in a situation can be exercised, and information conditions, which affect what the persons know and can communicate to each other. This chapter describes how we distinguish and represent those conditions.

Then we briefly consider the determinants of a situation and the question of its “reality.” Finally, we turn our attention to the “person factors” that enter into the interaction in particular situations. These are the interpersonal attitudes and values that people bring to and express through their interdependence. It will be recalled that our overarching model is that interaction is jointly determined by the situation and by the “person factors” of the two persons. In the Atlas's entries describing various important kinds of situation, we consider both the “person factors” relevant to each one and some of the patterns of interaction generated by partners for whom those particular factors are operative.

Recalling Eamon and Kyoko, we know that to accomplish their coordination task of removing the log that blocked their way, it was necessary for them to lift their respective ends at the same time.
