Therefore, communication is not only influenced by situational conditions and initial reactions but the "...social-historical context in which the interaction is embedded".

However, the decision about accommodation is not always necessary.

Imagine the encounter of two strangers, they may have a random small talk and simply say goodbye.

states that prior to acting, we attempt to assess the rewards and costs of alternate courses of action", and that we tend to choose whatever course of action will bring greater rewards and less costs.

Although most often convergence can bring forth rewards, there are some occasions when it can also bring forth costs such as "increased effort to converge, a loss of perceived integrity and personal (and sometimes group) identity".

Causal attribution process The causal attribution theory "Suggests that we interpret other people's behavior, and evaluate the individual themselves, in terms of the motivations and intentions that we attribute as the cause of their behavior" It applies to convergence in that convergence might be viewed positively or negatively depending on the causes we attribute to it: "Although interpersonal convergence is generally favorably received, and non-convergence generally unfavorably received, the extent to which this holds true will undoubtedly be influenced by the listeners attributions of the speaker's intent." Giles and Smith provide the example of an experiment that they conducted amongst French and English speaking Canadians to illustrate this.

In this experiment, when individuals believed that the person from the different group used language convergence to reduce cultural barriers, they evaluated it more positively than when they attributed it to the pressures of the situation.

Most of the time, the accommodation made according to those norms are perceived socially appropriate.

For instance, when a young person talks to the seniors in his family, he should avoid using jargons among his generation to show respect and communicate more smoothly.

When two people who speak different languages try to have a conversation, the language they agree to communicate with is more likely to be the one used by the higher status person.

This idea of "salient social membership" negotiation is well illustrated in the situation of an interview as the interviewee usually makes all efforts to identify with the interviewer by accommodating the way he speaks and behaves so that he can have more chance to secure the job.

The last assumption puts emphasis on social appropriateness and norms. expectations of behaviors that individuals feel should or should not occur in a conversation".
