A Japanese psychologist by the name of Sakai observed participants partaking in dissonance-reducing behaviors. Sakai also had a fellow group member of the participant observe the dissonance-reducing behavior. The observer then indicated how enjoyable he or she thought a boring task was. These results suggest that Japanese observers
a. attended to what their fellow group members said, and ignored the task itself.
b. have no internally based attitudes; those are a Western cultural phenomenon.
c. experience dissonance on behalf of fellow members of their group.
d. wanted to show solidarity with the experimenter by saying the task was enjoyable.

Experience dissonance on behalf of fellow members of their group

Explanation:

From the above, Sakai chose a group memeber from the participants to observe the dissonance reducing behaviour and then she indicated about how she felt about the tasks, this shows her indications are representative of the group under study as they correspond with the participants view of the task.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
