Precise time-matching in chimpanzee allogrooming does not occur after a short delay
Schematic illustration of the data collection method, consisting of continuous all-occurrence sampling of grooming events within vicinity of a designated focal animal (for scan of actual datasheet, see ref. , p. 32).
The original reason for designing the data sheet this way was to record the occurrence of polyadic grooming cliques: chimpanzees often groom within larger gatherings of individuals, which causes clusters of polyadic grooming , , such as triads (e.g. A → B ↔ C), quartets (e.g. A → B ↔ C ← D), or larger. Polyadic grooming is not the topic of the current paper, but the data sheets were usable for the analysis of dyadic grooming.
