Abstract
Current socioecological models suggest that the structure of female-bonded primate groups is predicated on the need for coalitionary support in compet itive interactions. Social grooming is thought to be the means by which fem ales ensure support from other individuals, either by the direct exchange o f grooming for aid or by using grooming as a means of strengthening social bonds. Since these relationships are valuable, they must be regularly servi ced and must be repaired if they become damaged. We question this position and show that empirical evidence to support these theoretical arguments is lacking. We then go on to present a new framework in which the inconsistenc ies regarding grooming and relationship negotiation are interpreted in the context of individual decision-making processes. In this framework, primate groups represent biological markets in which individuals either trade groo ming in a reciprocal manner for the direct benefits that grooming itself of fers, or exchange it for tolerance by more powerful animals. A number of te stable predictions are derived from this hypotheses. The need for socioecol ogical studies to focus on the dynamics of individual relationships rather than using summary measures is emphasized since only a detailed knowledge o f serial interaction will provide the key to understanding the complexities of individual decision-making processes.
