Joint and individual tool making in preschoolers: From social to cognitive processes.

Tool making has been proposed as a key force in driving the complexity of human material culture. The ontogeny of tool‐related behaviors hinges on social, representational, and creative factors. In this study, we test the associations between these factors in development across two different cultures. Results of Study 1 with 5‐to‐6‐year‐old Turkish children in dyadic or individual settings show that tool making is facilitated by social interaction, hierarchical representation, and creative abilities. Results of a second explorative study comparing the Turkish sample with a sample of 5‐to‐6‐year‐old children in New Zealand suggest that tool innovation might be affected by culture, and that the role of cognitive and creative factors diminishes through social interaction in tool making.
