 ToM nativism is compatible with the possibility that the development of ToM modules is shaped by environmental input. There are versions of modular ToM theory that emphasize the role of the developmental environment in shaping children’s ToMs. However, such versions of modularism hold that children are pre-set to acquire mentalistic concepts automatically through a process of triggering and tuning when appropriately stimulated (Segal 1996; Scholl &amp; Leslie 1999).
