Keeping track of needs in communal and exchange relationships.

Keeping track of needs in communal and exchange relationships was investigated in two experiments. In both, subjects could check to see if another person needed help. The first experiment tested the hypotheses that When there is no opportunity for the other to reciprocate in kind, keeping track of the other's needs will be greater if the person desires a communal relationship with the other than if the person desires an exchange relationship with the other. If the person desires an exchange relationship with the other, keeping track of the other's needs will be greater when an opportunity for the other to reciprocate in kind exists than when it does not. If a communal relationship is desired, the existence of an opportunity for the other to reciprocate in kind will not influence keeping track of the other's needs. The results of the first experiment supported all three hypotheses. The second experiment tested and found support for the hypothesis that even when nothing can be done to help the other, keeping track of the other's needs will be greater if a communal relationship is desired with the other than if an exchange relationship is desired.
