A wildlife biologist designed an observational study to compare the social grooming behaviours of adult chimpanzees in two different sanctuary environments: Enclosure A (highly enriched) and Enclosure B (standard enrichment). The sample consisted of 16 pairs of adult chimpanzees.
The observation took place from a dedicated viewing platform overlooking the enclosures. Each pair was observed covertly for 15 minutes by two trained researchers who independently recorded grooming interactions.
Additional context: The researchers employed these two trained observers to independently record the grooming and social contact behaviours of each chimpanzee during the sessions.
