concepts in this dimension include, 1) Situational Selection, or the "movement from one situation to another, bringing partners to a new situation that differs from the prior situation in terms of behavioral options or outcomes" (Van Lange & Balliet, 2014, p. 71), as well as what Axelrod coined 2) "The shadow of the future" (Van Lange & Balliet, 2014, p. 79), or long term strategy of cooperating in anticipation of future reciprocal rewards from the other individual in future interactions. Information availability. Information availability focuses on the amount of information individuals have concerning the other individual's motives, potential iteration outcomes, and the potential future opportunities any given interaction may bring about. This dimension suggests that misunderstanding is often rooted in low levels of information availability. An example of this would be if person A has certain information about the goals and motivations of person B, person A's actions will be effected differently than if that information was uncertain. Principle of transformation (what people make of the situation) Transformation is a psychological process through which individuals consider possible outcomes that result from both their action and the action of others, and weigh these outcomes against possible actions and courses of actions (Rewards and costs). Rewards and costs Interdependence theory stipulates that an ideal relationship is characterized with high levels of rewards and low levels of costs. Rewards are "exchanged resources that are pleasurable and gratifying," while costs are "exchanged resources that result in a loss or punishment." There are different types of rewards and costs discussed in this theory. This theory distinguishes between four types of rewards and costs. These types are as follows: emotional, social, instrumental, and opportunity. Emotional Emotional rewards and costs are the positive and negative feelings, respectively, that are experienced in a relationship. These types of rewards and costs are especially pertinent to close relationships. Social Social rewards and costs are those related with a person's social appearance and the ability to interact in social environments. Social rewards deal with the positive aspect of a person's social appearance and the enjoyable social situations in which one must engage. On the other hand, social costs are those that relate to the negative aspect of a person's social appearance and the uninteresting social situations to which a person must attend. Instrumental Instrumental rewards and costs deal with activities and/or tasks in a relationship. Instrumental rewards are those that are
