     Primate reconciliation studies have often relied upon an operational definition that compares the latency between conflict and the first affiliative post-conflict (PC) event with that of a control period (MC), categorizing dyads as either "dispersed" or "reconciled." Using this "PC-MC Method" (de Waal & Yoshihara, 1983), species with low social tolerances are often reported to also have low conciliatory tendencies (Thierry, 2000). However, members of an intolerant society may still benefit from repairing damaged relationships, and while a conflict may compel opponents to initially disperse, some dyads may postpone reconciliation rather than abandon it altogether. To reveal these "initial dispersal, delayed reconciliation" events, it is necessary to have an operational definition that does not rely on latency. Alternatively, one can compare a dyad's series of reconciliations interactions in the period following the First Affiliative Post-Conflict (PCFA) event with "Affiliative Matched Control" (MCA) periods, using equivalently-lengthed segments of baseline behavior that follow control-period event-markers (i.e. spontaneous affiliation that does not follow conflict). This "PCFA-MCA Method" was employed with free-ranging rhesus monkeys, a species characterized by low social tolerance and conciliatory tendency. Pearson correlations [a=0.05] using initial data from 19 adult females (84h) revealed non-significant PCFA increases in affiliative duration and frequency, including PCFA's following prolonged separation. While preliminary, these data suggest that the PCFA-MCA may reveal flexibility in post-conflict strategies that facilitate relationship repair while minimizing physical cost.
