This project investigates individual flexibility and differences in early human communicative behaviour, focusing on the role of gestural and vocal communication in the coordination of social actions. We will use an integrated multimodal approach to assess differences between individuals, age groups and cultural backgrounds. Social interactions will be recorded in day-care centres in Germany and in BaYaka Mbendjele villages in Congo Brazzaville, with focal children between the ages of 1.5 and 2 years or 3 and 4 years. By providing new insights into the communicative plasticity of human children, we aim to better understand the influence of socio-environmental factors on the development of multimodal communication in human children. In later stages of the project, comparisons with several great ape species will provide a better understanding of the evolutionary trajectory of hominin behaviour and communication.
