title: Ultradian behaviour cycles in a village community of Colombian Indians.
abstract: The daily activities observed in a Colombian village community of contemporary hunting and gathering people were analysed with respect to their time structure. Short term cycles of about 2 hours could be detected in both individual and common behavioural patterns. These behaviour cycles of individual group members appear to have been synchronised by social interaction. From temporal variations of individual activities a common ultradian time frame emerged.
